Recently, demands for developing offshore plants are increasing. Accordingly, the amount of orders of offshore plants exceeds 50 percent of total shipbuilding contracts of shipyards in South Korea. Also, occurrence rates of incidents in building offshore plants are increasing. In this respect, it is required that a safety management system is built for each shipyard or offshore plant building project. But, since task processes are similar regardless of the type of offshore plant that is built and shipyards, potential hazard factors and work process information could be commonly reusable. In this regard, we defined the information in XML formats and proposed a framework of the safety management system based on XML.


The analysis of autopoiesis as a tool for texture identification is presented in this paper, and a new computational model of autopoiesis, the T-SCL model, is proposed. This model makes use of an internal space, the A-space, as autopoietic processing domain. Computer simulations of the T-SCL model are shown and analyzed. Finally, a Texture Retrieval System based on the use of an autopoietic-agent is shown as a demonstrating example of the here proposed model.


Measurements are presented of absolute sputtering coefficients S for polycrystalline Au bombarded by 45‐keV ions with Zion ranging from 2 to 79. Low‐fluence results taken with chemically etched Au surfaces represent the first complete set of S values taken under the nearly ideal sputtering conditions of vanishingly small ion fluence and undamaged target surface. The results confirm unambiguously the smooth monotonic increase in S with Zion as predicted by sputtering theory. High‐fluence results are also obtained which are representative of implanted‐target surface conditions. These results exhibit the periodic variation of S with Zion as seen in past sputtering investigations.


Research on minimal unsatisfiable formulas and its subclasses is an active topic that begins to spring up in recent years.The splitting of formulas in minimal unsatisfiable formulas remains minimal unsatisfiability and some properties of the subclass are very useful for induction proofs based on the splitting technique.In this paper,it proposes a subset MAX﹢of constructing recursively minimal unsatisfiable formulas and proves that the method is complete and sound,at last it gives a structural example.


Traffic volume is a critical piece of information in traffic engineering and transportation planning. The observed values, however, are usually not precise; and hence, adjustment is necessary for them to satisfy various physical constraints, e.g. inflow = out-flow at every junction, in order to make them presentable. We propose a procedure that adjusts the observed values so that they meet the basic physical principle, such as the conservation of flow, given the subjective information about the characters of the observed values Adjustment is based on fuzzy optimization in which the observed values and basic knowledge about the relationship among the observed volumes are considered fuzzy. Fuzzy linear programming is used to find the adjusted values based on the max-min principle. The method is applied to estimate transit ridership at individual stops.


Modern high-performance computing (HPC) systems are typically accessed through interactive Linux shell sessions. Comprised of login and compute nodes, the system is accessed by researchers who will first access a login node and be provided a bash shell session. By default, bash shell histories are recorded up to a certain number of commands. Since 2013, Arizona State University HPC clusters have enabled a login-sourced shell utility to enable session histories to be recorded to a hidden user home directory. These HPC shell histories are typically utilized to help diagnose researcher issues as they arise and have proved to be invaluable in that respect. However, these histories may have additional value by being able to provide characterizations of how researchers engage with HPC systems, or perhaps be leveraged to foster collaboration or improve the HPC research cycle. This study documents a novel analysis of these prospective datasets by training two different machine learning methods on typical shell behavior as to detect a masquerading user.


A method was developed to measure transpiration rates and apparent water-vapor permeability coefficients (P' H2O ) of detached fruit using an analytical balance equipped with a humidity chamber, wide-range humidity-generating and sensing devices, and a datalogger. The system was designed to monitor weight changes with time and, hence, weight loss of individual fruit during exposure to specific relative humidities (RHs) and temperatures. Weight loss has corrected for loss due to respiratory exchange of O 2 and CO 2 before calculating P' H2O [...]

In this study, a nanostructured scaffold was designed for bone repair using hydroxyapatite (HA) and gelatin (GEL) as its main components. Nanopowders of HA were synthesized, and together with GEL, used to engineer a 3-dimensional nanocomposite combining 3 techniques of layer solvent casting, freeze-drying, and lamination. The results show that the scaffold possesses a 3-dimensional interconnected homogenous porous structure with a porosity of 82% and pore sizes ranging from 300 to 500 μm. It has also been shown that mechanical indices are in the range of spongy bones. Cultured osteoblast-like cells (SaOS-2) have shown an excellent level of cell attachment, migration, and penetration into the porosities of the nanocomposite scaffold. Here, we have shown that by a combination of widely available methods with simple experimental operations, nano-HA powders can be synthesized and used to make 3-dimensional HA/GEL nanocomposites in any desired shape, with mechanical properties comparable to spongy bone.


Background. Non-attendance in general practice has received increasing attention over the past few years. Its relationship with access to health care has been recognized. Missed appointments have serious clinical and economic consequences.
Study objectives: This study aims to identify the reasons for missing appointments in general clinics in Alwazarat health care center during the period from December 2010 to March 2011. Methods: All eligible patients who missed appointments to general clinics, in Alwazarat center and controls who show up for their appointment, were enrolled in the study using quasi-randomization for sample selection. On the same day of missing the appointment three clerks were assigned by the doctor in-charge of the center to assist in data collection. A structured phone interview was conducted with patients enrolled in the study and the control group using a validated questionnaire.

Results: The demographic factors associated with missing appointments were: female gender, younger age group and poor socioeconomic status. The important top five causes for missing appointments were: difficulty booking an appointment, work commitment, long distance travel, unavailability of transportation, visiting another health care facility. Among the group who missed appointment, the impact of missing appointment on health care service was unknown.

Conclusion: Knowledge of the factors that are associated with missed appointments facilitates the prospective identification of patients at risk of missing appointment and helps the continuous quality improvement for future planning which may include program modifications, and formulation of strategies to reduce the risk and rate of non-attendance.


The importance of accelerator R/D for particle physics research is emphasized and the dire necessity for finding new, economically efficient accelerating methods and technologies is pointed out.


A Thesis Submitted in Partial Fulfilment for the Degree of Master of Arts in Literature of Kenyatta University March, 2017.


The multi-parallel chopper system is commonly used in modern MW-level wind turbine converters. Even though the chopper is usually considered as robust and reliable, the semiconductor module can suffer critical junction temperature in extreme fault ride through (FRT) events. This paper proposes a method to monitor and identify if the individual chopper is functioning, degraded, or failed by means of collecting and comparing the parallel semiconductors' temperatures during FRT events. A simulation model is created in PLCES, the accuracy of which is further validated by a dedicated experimental setup including an infrared camera. The proposed method is verified by PLECS simulations.

Agricultural development in India depends primarily on the monsoon. Its auspicious beginning, nationwide spread and appropriation is essential to kharif crops. An Anand station is selected to the study the variability on a smaller period of the scale based on Nakshatras, which have an average period of 13-14 days. These daily rainfall data are recorded manually during 1958 to 2017 (60 years) are used to analyze Nakshatra-wise rainfall distribution in Anand (Middle Gujarat). It can be concluded that rainfall in Punarvasu and Pushya nakshatra is more assured than other nakshatra while it is the least assured in Magha and Purva nakshatra. Rainfall during June–July especially during Ardra and Uttarashadha nakshtra found positive 5% significant which is beneficial for paddy crop and while other nakashatra were non-significant with Pushya, Ashlesha. This knowledge will help in providing good knowledge having blend of experiences of old people and novel ideas of young generations for acceptability to farmers.

Team innovation and performance are a major concern for management. Paradoxical leadership can assist in sharing and obtaining knowledge from team members to enhance innovation and management needing to develop innovative team behaviour to share information amongst team members to improve innovation. The purpose of the current study is the mediating role of team perspective between paradoxical leadership, innovative work behaviour and team innovation. The sample size consists of 73 team members of University Departments at Qadisiyah. The 5 point Likert scale was used to obtain responses and PLS (AMOS) 3.0 was used to analyse the response. The study findings show that the role of paradoxical leadership needs to improve in assisting knowledge sharing and team innovation . However, team members have a strong sense of innovative work behaviour to share and obtain information from other members to enhance their sense of innovation. This study conducted was conducted at the University departments of . Respondents were taken from a large area. The study also suggests that team learning behaviour and a highperformance work system can assist the team perspective to enhance team innovation.


Recently the law of Environment has been created. So a mayor, in his town, the Perfect, in his department, can impose some obligations on the citizens about the fight against ragweed.


the sulphate of baryta. This result we can count upon with infible certainty. Given as a purgative, we cannot be sure of its action, although its power should be as certain and definite in the human frame as in the test-tube. The reason that we cannot be sure of its action as a remedy is because of differences in the conditions under which it is acting. It is our business to find out these -conditions, so that, when we, meet them again, we may know how to meet them. For there is an invariable relation between cause and effect, as invariable as the relation between an unchecked falling stone and the earth. We are, as I have said, just learning in medicine the paramount importance of tracing effects to their true cause. We may laugh at the credulity of the Middle Ages; when the way to cure a sword-wound was to apply a salve to the sword; when the only reason for the pestilence was the eccentric advent of some wandering fiery comet. But it is only with our own day that we improve upon the knowledge of our fathers; that, disdaining witchcraft, and spells, and delusions, and charms, and fables, we begin to see that the laws under which our bodies live are as immutable as the laws which govern Jupiter and the Pleiades; that, when we break them, we must suffer the penalty; that every infraction has its penalty. We learn that there is no such thing as an effect -without a cause; we learn, too, that the penalty for breaking one law will not attend the violation of another. It would be absurd to say that if a child killed a. fly it would have a pain in the stomach, and yet the time has been when such a statement would have been logical according to the accepted logic of medicine. The child may kill a fly-the child may have a pain in the stomach; but the pain does not result from the deed. The deed may lead to the pain in this, that the child may have to go dinnerless as a punishment for cruelty, and may gorge itself with green apples to supply nature's needs. But the penaltywould be for eating unripe fruit, not for killing flies. In the same way, an unrighteous community given to cheating, lying, and profane speech may be visited by an epidemic. But the epidemic would come, not as the penalty for broken scriptural commandments, but as the penalty for broken sanitary laws, the penalty for impure water, imperfect drainage, or communication with an infected district. The violation of scriptural laws may lead to buildings being scamped, to imperfect drains, and a polluted water-supply. But simple repentance for these sins will not stop the epidemic until the sanitary laws are observed. The laws of nature admit of no exception and no excuse. The rain falls alike on the just and the unjust. If a viaduct break and a train be thrown into the river or the valley, the good and the bad alike suffer. Good and bad alike suffer, because, whatever respect they may have shown to moral laws, in this case they have offended the law of gravity-a law which exacts their lives or 4eir limbs as its penalty. If a man swallow poison, the poison will do its work, whether the act of taking was a conscious or an unconscious act. This knowledge has enabled us to avert danger from ourselves and from those who, like children, would, in their ignorance, swallow the bright and tempting berry merely because it was pleasing to the eye, unconscious of the deadly principles lurking in its core. It is only within a short time that we have learned that men may become dull, listless, unable to command their faculties, because of the poisonous fumes from a fireplace or a stove, or the impalpable powder that floats from the arsenical paper decorating the walls. We know that the green tracery which scatters garlands and vines over our modern walls may be as death-dealing, because of this 'unseen arsenical presence, as the fumes of carbonic acid gas. We know that a whole district may fall under the terrible scourge of typhoid fever because the water-supply has found some contamination. We know that dinnerguests may be affected by scarlet fever because of ices composed of milk which contained the virus of that disease.* The laws of nature are independent of our fancies. We must conform to them, or suffer the penalty of disobedience and neglect. Ignorance will not prevent disease. A physician's fancies as to the cause of a disease, or the nature of a remedy, will not check it. It is only by knowing as a truth, by patient study and investigation, the exact causes of disease, that we can avoid it. It is only by knowing these causes, the value of the remedies which will affect them, and the conditions of the human frame under which these remedies can have their full influence, that we can effect a cure. How this is to be done, is the subject to which I propose to address myself in the next lecture.


(172 words) Consider a situation where a single member of a haploid population possesses a duplicate copy of a gene whose presence is vital for the survival of the organism, and where the duplicate is fully linked to the original gene's locus. Any copy of the gene is subject to mutations which destroy its function. Preservation is said to occur if eventually the entire population consists of individuals descended from the initial single duplicate. This event can be compared to a situation where a single individual carries a selectively neutral gene variant, in which the probability of preservation is just the reciprocal of the population size. The system is modelled by a finite state-space Markov process which in turn is approximated by a diffusion process. An explicit expression for the ratio of probabilities of preservation of a gene duplicate to that of a neutral variant on the gene is derived, and asymptotic methods are used to show that in the high-mutation limit this ratio approaches two. This is in excellent agreement with simulation studies.


After intensive chemotherapy, the emergence of cells with drug resistant and/or stem cell features might explain frequent relapses and the poor outcome of patients with acute myeloid leukemia (AML). Herein, we first uncovered that the adrenomedullin receptor CALCRL is overexpressed in AML patients compared to normal cells and preferentially in the immature CD34+CD38- compartment. Then, we demonstrated its role in the maintenance of leukemic stem cell function in vivo (Figure A). Moreover, CALCRL depletion strongly affected leukemic growth in xenograft models and sensitized to chemotherapeutic agent cytarabine in vivo. Accordingly, we showed that ADM-CALCRL axis drove BCL2 pathway, cell cycle and DNA integrity in E2F1-dependent manner, and high OxPHOS status that we previously described as a feature of minimal residual disease after chemotherapy (Farge et al., 2017). Moreover, CALCRL expression predicted the response to chemotherapy in vivo in mice (n=10 Patient Derived Xenografts; Figure B) and in patients. Further, using the combination of limiting dilution assays, single cell RNA-seq analysis of primary AML samples at diagnosis and relapse and before and after transplantation in NSG mice, we revealed the pre-existence of a chemoresistant leukemic stem cell sub-population harboring a CALCRL gene signature (Figure C-D). All of these data highlight the critical role of CALCRL in stem cell function and metabolism. They also identify this receptor as a new druggable marker of chemoresistant leukemic stem cell population and a promising therapeutic target to specifically eradicate them and overcome relapse in AML.

Measurement of the maximal inspiratory mouth pressure (PImax) is a simple, reproducible, and non-invasive method frequently used for estimation of the inspiratory muscle strength. The aim of the study was to assess the PImax values in well-trained representatives of the endurance sports and to determine the basic relationships between these values and age, training experience, somatic indices and aerobic capacity of the tested subjects. Overall, thirty female and thirty-five male elite junior and senior representatives of the endurance sports were included in the investigation. PImax and maximal oxygen uptake (VO2max) were estimated in all the subjects. In the female athletes the obtained mean PImax values (11824 cm H2O) were significantly lower than the respective values estimated in their male counterparts (14325 cm H2O). Of all the tested relationships significant correlation was detected only between PImax and VO2max in the females (r=0.475) and only between PImax and the body mass index (BMI) in the males (r=0.501). Since the published values of PImax vary greatly depending, among other factors, on the studied population, methods and techniques of the measurement and motivation of the tested subjects it is suggested that each laboratory elaborate its own reference values. The results indicate that in the female and in the male athletes the inspiratory muscle strength is not related to the body size. On the other hand, the detected correlation between PImax and BMI in the males may suggest a possible relationship between the inspiratory muscle strength and the total muscle mass. Presumably, endurance training in the well- trained individuals can not enhance any more the inspiratory muscle strength or the described relationships are indirect and depend on the intersexual differences.

Introduction System development for Internet and WEB environments has become the knew trend of the software engineering. Internet and WEB are the largest scale platform available nowadays. The usage of the WEB as a platform to deploy information systems provides to its users an extremely easy and universal access. Several kinds of users can benefit from the system features independent of their location. Electronic patient records (EPR) can make use of this WEB characteristics to provide global access to patient information. EPRs integrate different views of patient information while supporting different tasks of health care, performed by a number of health professionals[ I]. This work intends to present the principal aspects involved in a WEB-based electronic patient records development. This aspects are being identified during the development phases of a project to construct and deploy a medical record system in a WEB-based environment, presently in course at the UFPE/Brazil.

This paper fuses ideas from computational geometry, network theory and linear systems theory in order to develop a new tool for piecewise linear systems analysis. Specifically system models with piecewise linear functions such as saturation, relay and dead zones are represented as directed connected node graphs that capture information concerning the system's global dynamics. Logic, such as rules within a rule-based controller, can also be mapped into the node graph of the system, thus showing the interaction between the logic and the system dynamics. The node graph is reminiscent of a phase portrait in that it gives a graphical representation that can aid analysis and potentially design. Unlike the phase portrait, the method is applicable to system models of more than two states. As a consequence, piecewise linear systems of arbitrary order may be studied and their stability patterns revealed.<<ETX>>


Summary:  Purpose: Determination of epilepsy etiology in population‐based studies is difficult because of the high cost of diagnostic tests. However, cost‐effectiveness may be proven if preventive public‐health strategies can be established from the test results. We report an epilepsy population‐based study using clinical and laboratory techniques.


Introduction Orotracheal intubation becomes a challenge for the anesthesiologist when the glottis is not visualized with direct laryngoscopy. Videolaryngoscopes emerged as an alternative in these situations, but the costs of these devices restrict their popularization. Doubts remain as to whether low-cost devices would be safe and effective, such as the 3D printing Open-Source video laryngoscope. Aim To analyze the 3D printing Open-Source video laryngoscope for orotracheal intubation for general anesthesia in its the rate of achieving, glottis visualization time, intubation time and its correlation with the order of execution. Methods Clinical, prospective, analytical study of a questionnaire carried out after the procedure. Statistical analysis was performed using Spearman's correlation, Kruskal-Wallis test, and chi-square test. Results There was a total of 64 uncomplicated orotracheal intubation procedures with an overall success rate of 93.8%. Mean time for viewing the glottis (16.4"), mean times of endotracheal intubation with Mallampati I (26.5"), ll (33.7"), lll (57.3"), lV (38.5") were obtained with no statistical significance (P 0.170) and overall mean time of orotracheal intubation (36.4") with a moderate negative correlation of –0.36 across the orotracheal intubation execution order. Conclusion In the analysis of endotracheal intubation with the 3D printing Open-Source video laryngoscope a high success rate was demonstrated without any complications. The time to obtain endotracheal intubation tends to reduce with subsequent experiences and learning, but it is more than twice the time required to adequately visualize the glottis and the Mallampati classification was not a relevant time predictor. Keywords: Orotracheal intubation; Videolaryngoscopy, Airway management

Investigations on the host specificity of plerocercoids of Schistocephalus solidus were carried out using the technique of surgically transferring plerocercoids from the body cavity of Gasterosteus aculeatus to various other fish. Plerocercoids survived in all cases when transferred from G. aculeatus to other G. aculeatus; when tranferred to Pungitius pungitius the worms survived for long periods but failed to grow. Plerocercoids transferred to Coitus gobio, Nemacheilus barbatula, Phoxinus phoxinus, Salmo trutta, Coregonus clupeoides, Perca fluviatilis, Rutilus rutilus and Esox lucius always died within 2–10 days after being transferred. Electron-microscopic examinations of the tegument of plerocercoids transferred to new hosts showed: in G. aculeatus normal appearance throughout the experiment; in P. pungitius degeneration of the microtrichs after 6 days; and in S. trutta complete destruction of the tegument in 7 days. Plerocercoids of the genus Diphyllobothrium survived the transfer from Gasterosteus aculeatus to Salmo trutta and continued to grow in their new host. Infection of fish with S. solidus by feeding infected copepods and by aspetic injection of procercoids into the body cavity of the fish were also tried. Gasterosteus aculeatus became infected using both these methods but it was not possible to infect Pungitius pungitius.

I entered the Church of Scientology on a crisp winter's afternoon. My ears, on the church's behalf, were burning. Within the previous month the South Australian Opposition leader had resigned after a Scientology-linked scandal, prosecutors in France had relaunched a long standing action to have the church banned, Wikipedia had halted an 'edit war' between Scientology and its critics, Scientology's leader had denied accusations of being a violent psychopath, and Jodhi Meares and Peaches Geldof had reportedly joined up. Scientology was in the news. Scientology is always in the news. The sign outside the church offered the 'Free Personality and IQ Test', Scientology's traditional welcome mat. I affected the nervous curiosity of somebody I imagined would want to take such a test. But I came to learn, not to ridicule. An hour later I left the building; I had been propelled on a path towards becoming a Scientologist, and I might even have already become one.

We present results of an analysis of the structural and kinematical properties of a sample of elliptical-like objects (ELOs) identified in four hydrodynamical self-consistent simulations run with the DEVA code (Serna, Domínguez-Tenreiro, & Sáiz). Star formation has been implemented in the code through a simple phenomenological parameterization, which takes into account stellar physics processes only implicitly through the values of a threshold gas density, ρg, thres, and an efficiency parameter, c*. The four simulations operate in the context of a Λ cold dark matter cosmological model consistent with observations, resolve ELO mass assembly at scales up to ≃2 kpc, and differ in the values of their star formation parameters. Stellar masses, projected half-mass radii, and central line-of-sight velocity dispersions, σlos, 0, have been measured on the ELO sample and their values compared with data from the Sloan Digital Sky Survey. For the first time in self-consistent simulations, a good degree of agreement has been shown, including the Faber-Jackson and the Dn-σlos, 0 relations, among others, but only when particular values of the ρg, thres and c* parameters are used. This demonstrates the effect that the star formation parameterization has on the ELO mass distribution. In addition, our results suggest that it is not strictly necessary, at the scales resolved in this work, to appeal to energy sources other than gravitational (as, for example, supernovae feedback effects) to account for the structure and kinematics of large elliptical galaxies.


In 1961, Richard and Mary Bunge discovered and reported the phenomenon of spontaneous myelin repair using an animal model of demyelination [1]. Only four years later, the same possibility was observed in specimens from patients diagnosed with multiple sclerosis (MS), what would eventually be the starting point of a true scientific revolution – the demonstration that the human central nervous system (CNS) may be able of spontaneous self-repair [2]. Since then, over the past decades, some speculation has been produced about the possibility of developing new drugs that could enhance or improve spontaneous remyelination in MS. Although difficult, this goal seems to be getting closer and new therapeutic agents are being developed to fill this gap in MS care, accompanying an increasingly deep understanding of the biology of remyelination.


The braking system is one of the most important and complex subsystems of railway vehicles, especially when it comes for safety. Therefore, installing efficient safe brakes on the modern railway vehicles is essential. Nowadays is devoted attention to solving problems connected with using high performance brake materials and its impact on thermal and mechanical loading of railway wheels. The main factor that influences the selection of a friction material for railway applications is the performance criterion, due to the interaction between the brake block and the wheel produce complex thermos–mechanical phenomena. In this work, the investigated subjects are the cast–iron brake shoes, which are still widely used on freight wagons. Therefore, the cast–iron brake shoes – with lamellar graphite and with a high content of phosphorus (0.8–1.1%) – need a special investigation. In order to establish the optimal condition for the cast–iron brake shoes we proposed a mathematical modelling study by using the statistical analysis and multiple regression equations. Multivariate research is important in areas of cast–iron brake shoes manufacturing, because many variables interact with each other simultaneously. Multivariate visualization comes to the fore when researchers have difficulties in comprehending many dimensions at one time. Technological data (hardness and chemical composition) obtained from cast–iron brake shoes were used for this purpose. In order to settle the multiple correlation between the hardness of the cast–iron brake shoes, and the chemical compositions elements several model of regression equation types has been proposed. Because a three–dimensional surface with variables on three axes is a common way to illustrate multivariate data, in which the maximum and minimum values are easily highlighted, we plotted graphical representation of the regression equations in order to explain interaction of the variables and locate the optimal level of each variable for maximal response. For the calculation of the regression coefficients, dispersion and correlation coefficients, the software Matlab was used.


The global warming expected from climate change might be prevented by a restriction on carbon emission. This mitigation can be realized by several market friendly or discretionary institutional ways. A market friendly pricing of externalities is the carbon emission tax. The EU emphasizes the importance of environmental sustainability in relative outstanding extent in global comparison. The EU has been an initiator of international cooperation for the mitigation of climate change and has essential role in the creation of the Kyoto Protocol for example. The international cooperation can cope more easily with quantitative regulations like permit trade (namely quota trade), since taxation is part of sovereign fiscal policy. But therefore, green taxation is absolutely a national and a little bit single market responsibility to foster the mitigation. Therefore, it is important to check carbon tax practices of EU countries, whether are they so enthusiastic in national competence level as in global representation. As it is written by O'Hara (2009), "[...] global warming hypotheses have been a contested terrain as advocates sparred with critics, resulting in controversy and analysis, but no firm resolution either way at the level of public debate. All this has suddenly changed in the light of the 'global warming' thesis gaining the upper hand. The influence of [...] publication of the IPCC Report (2007a,b,c,d), the Stern Review (2007), the UNDP Report (2007), and the Garnaut Report (2008) [...]have meshed with the election of more moderate governments in several continents to


In the ISCHEMIA trial, patients with chronic coronary syndromes (CCS) and moderate or severe ischemia had no significant difference in combined ischemic events with an initial invasive compared with a conservative strategy [1]. Coronary computed tomography angiography (CCTA) was part of the pre-randomization workup of ISCHEMIA and is gaining popularity over ischemia testing or initial invasive coronary angiography (ICA) as the initial diagnostic strategy for CCS [2].

 To analyse whether the results of the ISCHEMIA trial had a sizeable impact on the diagnostic algorithm for CCS by analysing trends in referral to ICA and/or revascularization.

 ICAs performed in CCS patients between November 2019 and February 2022 at a high-volume centre were analysed. Two groups were defined based on procedure date: i) pre-ISCHEMIA, including ICAs performed before March 2020 (date of trial publication); ii) post-ISCHEMIA, including ICAs performed ≥3 months (i.e., blanking period) after trial publication. The primary outcome was the incidence of referral to ICA by CCTA. Secondary objectives included referral to ICA or revascularization by ischemia testing, referral to revascularization by CCTA, and referral by CCTA to ICA that did not require further intervention.

 A total of 2,365 patients qualified for the analysis, of which 487 (20.6%) and 1878 (79.4%) in the pre-ISCHEMIA and post-ISCHEMIA groups, respectively. There were no notable differences in baseline characteristics between groups. The primary outcome occurred more frequently in the post-ISCHEMIA group (73.5% vs 32.5%, p<0.01). Referral to ICA by ischemia testing was lower in the post-ISCHEMIA group (31.6%, vs 52.5% p<0.01), while referral for revascularization by CCTA was more frequent (8.3% vs 12.0% p<0.01). There were no significant differences in referral to revascularization by ischemia testing (3.4% vs 3.0%, p=0.73) and referral by CCTA to ICA that did not require further intervention (60.3% vs 60.8%, p=0.90).

 At two years from publication, the ISCHEMIA trial seems to have impacted significantly on the decision-making algorithm for patients with CCS. The frequency of referral to ICA and revascularization by CCTA considerably increased, paralleled by decreased referral to ICA by ischemia testing.

We present a series of two-phase (oil and gas) drainage and imbibition relative permeability (kr) curves at near-miscible (IFT=0.04 mN/m) conditions. An equilibrium mixture of methane/n-Butane at 38°C and 1840 psia was used as the oil and gas in the unsteady-state coreflood experiments which were carried out to obtain the kr curves. A high-permeability (1000 mD) and a lower permeability (65 mD) cores were used in the experiments and both water-wet and mixed-wet wettability conditions were examined. The results show that the present of immobile water saturation in water-wet cores could improve oil relative permeabilities and reduce gas relative permeabilities in both imbibition and drainage directions. The results show that despite a very low gas-oil IFT, there is still significant hysteresis between imbibition and drainage cycles for both the oil and gas relative permeabilities in the 65md core. The results help us better understand the impacts of some of the important parameters of multiphase flow through porous media on kr curves and their hysteresis especially in low IFT gas-oil systems and mixed-wet rocks. Obtaining accurate kr and kr hysteresis is extremely important for predicting the performance of gas injection in oil reservoirs.


In a real-time database system for detection of critical events,On co-scheduling of periodic update and application transactions with fixed priority assignment for real-time monitoring meeting the deadlines of the application transactions and maintaining the quality of the real-time data objects are two critical issues in ensuring the effectiveness of performing the real-time monitoring tasks. Unfortunately, these two goals conflict with each other and are difficult to be achieved at the same time. To address this update and application transaction co-scheduling problem, in this paper, we propose a fixed priority scheduling algorithm called Periodic Co-Scheduling (PCS). PCS uses periodic update transactions to maintain the temporal validity of real-time data objects. It judiciously decides the priority order among all the update and application transactions so that the constructed co-schedule can satisfy the deadline constraints of all the application transactions while maximizing the qualities of the real-time data objects. The effectiveness of the PCS algorithm is validated through our extensive simulation experiments.


We demonstrate reliable and durable (>100 write/erase cycles) bipolar resistive electrical switching of silver tetracyanoquinodimethane (AgTCNQ) based memories by incorporating a dedicated SiO2 "switching layer" and limiting the on state current by a current compliance. Switching back to the off state required voltages of opposite polarity with higher current intensity; keeping the same current compliance level typically prevented—and exceptionally lead to time delayed—off switching. Simultaneous growth and dissolution of the conductive channels could be observed during the on to off transition. All of these findings give further evidence that the switching mechanism involves electrochemical processes.


This article presents the fascinating personality of Berti Eckert (born in Gorizia in 1915) who, after a distinguished career as student and rabbi in Italy, immigrated to Palestine in 1938 with the first Italian aliat ha noar. In 1941 he founded the kibbutz Yavne in Israel and since 1952 he has been involved in a number of Jewish educational missions in Italy. Through a series of unpublished letters and biographical writings from 1929 to 1951 the life of Berti Eckert and his brothers - Massimilano, Elvira and Sidonia - in Italy and in Palestine is reconstructed during the crucial and dramatic experiences during the Nazi-Fascist domination. Through the story of Berti Eckert and his entourage we can see mirrored the complex path taken in the first part of 20 th century in the framework of assimilation, Zionism, Fascism and religious repossession, in different ways and times, by the entire Italian Jewish society.

Coherent backscattering and other phenomena of multiple-scattering of light have found a wide range of applications from the studies of wave diffusing in random media, in acoustics, random lasers, characterization and calibration of nano-scale materials, in magneto-optical traps to the planetary astronomy, with the observance of the opposition effect. With the high dependence on the coherent properties of light and the internal structure of the probing sample the coherent backscattering have the ability to detect morphological changes at the intra-cellular level. The technique has the potential to be so specific that it will revolutionize the currently used procedures for melanoma and pre-cancer detection. In current report a coherent backscattering experiment has been performed using a modified Michelson interferometer experimental setup with a He-Ne laser upon a phantom material.


Globalization that matches the nature of shipping companies has to be a key factor for their organizational structure and operation. A growing number of them, to exploit the benefits of international integration of capital markets, have adopted a more specific organizational structure trying to implement corporate governance mechanisms. Meanwhile, the majority of maritime firms, particularly with headquarters in Greece, continue to operate in a traditional basis, since the family capitalism still holds the scepters. This article aims to assess the role of corporate governance as a determinant of the operational and financial performance of maritime business, raising questions for further investigation. It reviews the literature on corporate governance practices, focusing on maritime firms trying to analyze the effects of corporate governance in their financial performance. Research on corporate governance in the shipping sector, despite the growing stream of related studies, remains still understudied. This is the reason why empirical findings of the reviewed studies should be treated with caution, since the theoretical framework in corporate governance is still under investigation in shipping. Further research needs addressing all major subsystems of a maritime firm, so as their impact on governance structures of maritime business to be evaluated and measured.


The traverse route from Zhongshan Station to Dome-A is one of the most important expedition routes of ITASE Project.China carried out 3 inland traverses during the 1996/1997, 1997/1998, 1998/1999 austral summer field seasons.The field team reached inland 300 km, 500 km and 1100 km away from Zhongshan Station respectively.Some ice motion stakes were set up, occupied and reoccupied along the route by GPS technology.It showed that the ice along the traverse route flowed with an 8-25 ma-1 velocity to the northwest, the direction of the bottom of Lambert Glacier Basin.They coincide with the results along the eastern section from LGB59-70 of the LGB route deduced by Australia in both values and directions.Furthermore, the directions of the horizontal flow are perpendicular to the surface topography contour.The much larger velocity at the point of LT980 with an approximate value of 100 ma-1 was probed.It was caused by a 15 km wide trough on the bed beneath this point.


We are working on a common information model called UNIWBS which uses the work breakdown structure concept. UNIWBS is intended to support project information integration and project planning and control as well. By using the UNIWBS, we are also developing a conceptual knowledge-based expert system called DYNAPACK for generating planning, design, and construction work packages. DYNAPACK will be a testbed to support timedependent project information evolution.


In order to deal effectively with the problem of narcotics addiction, it is necessary to determine precisely what harms we wish to control. To protect the public from the violent crime that seems to be associated with drug addiction, it may be appropriate to resort to the model of "civil commitment," to provide compulsory treatment to those drug users who are thought likely to inflict harm on others as a result of their addiction. On the other hand, to protect the user from drugs which are harmful only to him, it may be appropriate to resort to the regulatory model by which we control the distribution of other hazardous consumer goods. Neither interest is well served by the criminal model on which we now rely. Language: en

The article focuses on the admissibility of limiting constitutional rights of citizens when checking the information about their disappearance. In accordance with clause 12 of the Instruction on the procedure of consideration of applications, crime reports and other information on incidents involving disappearance of citizens approved by Order No. 38/14/5 of 16.01.2015, upon receiving an application about disappearance of a person, all circumstances related to the event of his/her disappearance (time, place, method etc.), information characterizing his/her personality and psychoemotional state, the circle of his/her relationships and contacts are investigated in detail. Due to the necessity to identify a  ircle of the missing person's relations and contacts, the problem arises about the investigator's access to the protected by the Constitution of the Russian Federation secrecy of telephone conversations, in particular the information in the memory of the mobile phone of the missing person. In accordance with article 23 of the Constitution of the RF, everyone has the right for secrecy of correspondence, telephone conversations, postal, Telegraph and other messages. The limitation of this right is allowed only based on a judicial decision. It appears that the inspection of information contained in the mobile phone of the missing person may be made only on the basis of a judicial decision, due to the impossibility to have the owner's voluntary consent.


The purpose of this study is (1) to explain the use of grammatical cohesion in the aspects of reference, substitution, ellipse, and inner conjunction; (2) explain the quality of the use of grammatical cohesion markers in the Singgalang newspaper. The object of this research is the Singgalang newspaper with a total sample of 20 Singgalang newspapers. Samples were taken randomly from Singgalang newspapers in 2018 and 2019. The methods and techniques of data collection are language methods. The technique used is the library method by dividing the discourse into several sentences to be grouped and analyzed based on the cohesion aspects, then proceed with the basic tapping technique followed by the note-taking technique. The results showed that out of 212 paragraphs with 602 pairs of sentences with grammatical cohesion, there were markers of grammatical cohesion from the dominant to the least used, namely (1) reference (54.82%), (2) conjunction (32.89%) , (3) ellipsis (5.81%), and (4) substitution (3.65%). From the research data, there are 48.00% accuracy in using markers of grammatical cohesion and 52.00% inaccuracies in the use of markers of grammatical cohesion.


In this paper, an efficient digital predistortion (DPD) architecture utilizing over-the-air (OTA) feedback is presented to linearize phased array transmitters. It places one additional observation antenna (OA) in the far field to capture the combined signal of the array outputs and uses the combined signal to build a nonlinear model that describes the joint nonlinear distortions of all the power amplifiers (PAs) in the phased array. Then, a corresponding DPD model is extracted by the typical indirect learning method to linearize the phased array. After introducing this DPD architecture, the relationship between the OA position and the performance of the extracted DPD model is specifically explored, and two significant results are found. First, when the OA is perfectly colocated in the main beam direction, the DPD coefficients extracted with an arbitrary steering angle for the phased array are also applicable to any other steering angle. Second, when the OA is not perfectly placed in the main beam direction, the linearization performance for the extracted DPD coefficients will degrade as the OA placement mismatch increases, and the phased array has an optimum steering angle at which the OA placement mismatch has a minimal influence on the DPD performance. Based on the above two results, a new DPD training strategy is proposed, which extracts only one set of DPD coefficients by making the phased array point at the optimum steering angle. The advantages of the proposed strategy are that the OA can be placed in a relatively wide range of positions and that the extracted coefficients will be applicable to any other steering angle. The two results and the proposed DPD training strategy are verified by simulations, which are conducted on a $1\times 4$ uniform linear array (ULA) and a $4\times 4$ uniform rectangular array (URA).


In late 2006, ground-based photometry of η Car plus the Homunculus showed an unexpected decrease in its integrated apparent brightness, an apparent reversal of its long-term brightening. Subsequent Hubble Space Telescope (HST)/WFPC2 photometry of the central star in the near-UV showed that this was not a simple reversal. This multi-wavelength photometry did not support increased extinction by dust as the explanation for the decrease in brightness. A spectrum obtained with the Gemini Multi-Object Spectrograph on the Gemini-South telescope revealed subtle changes mid-way in η Car's 5.5 yr spectroscopic cycle when compared with HST/Space Telescope Imaging Spectrograph (STIS) spectra at the same phase in the cycle. At mid-cycle the secondary star is 20–30 AU from the primary. We suggest that the spectroscopic changes are consistent with fluctuations in the density and velocity of the primary star's wind, unrelated to the 5.5 yr cycle but possibly related to its latitude-dependent morphology. We also discuss subtle effects that must be taken into account when comparing ground-based and HST/STIS spectra.

Background and Objective: Increasing the intensity of training is one of the factors that improve the athletic performance. Evaluation of psychological and biochemical factors is believed to be beneficial for evaluating the effectiveness of training schedule. Previous studies have shown that there are various responses to the training intensity due to the level of athlete's fitness and the kind of training. This study was done to investigate the effect of intensive training on salivary level of cortisol , test osterone, αamylase and mood of elite adolescent wrestlers. Materials and Methods: This quasi-experimental study was performed on fifteen adolescent wrestlers of Iranian national team during 2009. The subjects were under extension training for three weeks. The saliva samples were taken prior, first, second and third weeks of training to determine cortisol, testosterone and α-amylase level of salivary samples. Also, the Brahms questionnaire was used to assess the mood profile before and after the training. Data were analyzed using SPSS-14, ANOVA and student t-tests. Results: There was no significant differences of salivary cortisol (7.69±0.75, 8.1±0.93 ng/ml), testosterone (82.3±0.89, 64.2±1.7 ng/ml), α-amylase (98.81±1.35, 84.2±1.5 U/ml) level and mood (16.4±3.28, 20.08±2.91) of subjects prier and after training. Conclusion: This study indicated that the intensive training do not alter salivary hormons level and mood of elite adolescent wrestlers.

Abstract : LPI radar is a class of radar systems that possess certain performance characteristics that make them nearly undetectable by today's digital intercept receivers, This presents a significant tactical problem in the battle space To detect these types of radar, new digital receivers that use sophisticated signal processing techniques are required This thesis investigates the use of cyclostationary processing to extract the modulation parameters from a variety of continuous-wave (CW) low-probability-of- intercept (LPI) radar waveforms, The cyclostationary detection techniques described exploit the fact that digital signals vary in time with single or multiple periodicities, because they have spectral correlation, namely, non-zero correlation between certain frequency components, at certain frequency shifts, The use of cyclostationary signal processing in a non-cooperative intercept receiver can help identify the particular emitter and can help develop electronic attacks, LPI CW waveforms examined include Frank codes, polyphase codes (Pt through P4), Frequency Modulated CW (FMCW), Costas frequencies as well as several frequency-shift-keying/phase-shift-keying (FSK/PSK) waveforms It is shown that for signal-to-noise ratios of OdB and -6 dB, the cyclostationary signal processing can extract the modulation parameters necessary in order to distinguish among the various types of LPI modulations.


Several design of corrugated carton boxes for ceramics vase have been developed by using single and double wall corrugated carton with different gramature 1251125/125,15011501150 and 150112511251150. The evaluation is made by comparing their characteristic through the physical test such as compression, drop and vibration test. The result shows that the single wall corrugated board with gramature 15011501150 have good physical characteristic. With regard to the economic point of view, the gramatur 15011501150 single wall corrugated board is recommended for packaging of cearamics vase, especially for export.


The management of thyroid carcinoma patients suspected of recurrent disease by different diagnostic modalities and some discordance between them presents considerable problems. The purpose of this study is to determine the roles of FDG-PET and other conventional diagnostic modalities, such as thyroglobulin (Tg), thyroglobulin antibody (Tg-Ab), I-131 WBS, US, CT and MRI in the management of these patients. Methods: Forty thyroid carcinoma patients who underwent FGD-PET studies are included in this study. Whole-body images were acquired 1 h after intravenous injection of 370 MBq (10 mCi) FDG using a PET scanner. Results of FDG-PET studies were evaluated by histopathology, CT or MRI, and follow-up of Tg levels in 2 years clinical follow up period. Results: Sixteen patients had positive findings on PET, which were proven to be true-positive in 15 patients, whereas 1 patient had false-positive finding. 24 patients had negative scans. These were true-negative findings in 12 patients, whereas the remaining 12 patients had false-negative results, 6 of them had positive I-131 WBS. Cervical US was the only test which determined cervical lymph node metastases in two patients with TSH-stimulated Tg ! 0.2 ng/ml. Tg levels of all true negative cases were less than 5 ng/ml. FDG-PET revealed metastatic foci in two patients with very high TgAb levels and negative I-131 WBS. Conclusions: FDG-PET is a valuable diagnostic tool in patients with differentiated thyroid cancer who present with increased Tg levels of 1 5 ng/ml and negative 131 I scans. Elevated TgAb levels are also an indicator of recurrent disease and FDG-PET is also very useful in these patients. US is the most sensitive method to detect local recurrence and lymph node metastases at an early stage and should be performed at all routine check-ups. Thyroid Cancer


Several hours before his assassination in 1948, Mahatma Gandhi submitted his proposal for revisions in the party constitution of the Indian National Congress. He suggested that the Congress dissolve, since partisanship appeared to him wrong, and convert itself into a Lok Sevak Sangh, an apolitical people's service association. The Congress did not in the event obey the testament, but no one thought the proposal funny or outrageous. More recently, a General Secretary of the Congress reiterated the non-partisan point of view underlying this proposal when he questioned whether the role of an opposition party was meaningful in India, and when he supported the idea of "a common national programme acceptable to all political parties, on the basis of which the administration of the country could be carried on." "The Panchayat system in India," the Secretary said, "was essentially based on this very principle of synthesis rather than antithesis. Economically underdeveloped countries like ours can hardly afford the luxury of opposition only for the sake of opposition."


The photoanode of a dye-sensitized solar cell (DSC) utilizing Ti-mesh electrode is fabricated for high-efficiency, low-cost solar cell application. Ti-mesh electrode replaces transparent conducting layer (TCO). The TCOless DSC is composed of a glass/dye sensitized TiO2 layer/Ti-mesh electrode/electrolyte/metal counter electrode. The Ti-mesh electrode with high conductivity can collect electrons from the TiO2 layer and allows the ionic diffusion of I−/I3− through the mesh hole. Thin Ti-mesh(≈40 μm in thickness) electrode material is processed using the rapid prototype method. Both the photocurrent (6.02 mA/cm2) and fill factor (0.303) are low, and these can be further improved by controlling the pore size and thickness of the mesh, and the contact between the TiO2 particles and the Ti-mesh metal, respectively.


We investigate the origin of the matching effect observed in disordered superconducting NbN thin films with a periodic array of holes. In addition to the periodic variation in electrical resistance just above the superconducting transition temperature Tc0, we find pronounced periodic variations with magnetic field in all dynamical quantities that can be influenced by flux-line motion under an external drive, including the magnetic shielding response and the critical current, which survives in some samples down to temperatures as low as 0.09Tc0. In contrast, the superconducting energy gap Δ, which is a true thermodynamic quantity, does not show any periodic variation with magnetic field for the same films. Our results show that commensurate pinning of the flux-line lattice driven by vortex–vortex interaction is the dominant mechanism for the matching effects observed in these superconducting anti-dot films, rather than a Little–Parks-like quantum interference effect.


Phosphorous (P) is essential to bone growth and maintenance; however, little research has focused on the genetic mechanisms controlling P utilization. Thirty-six pigs from two sire lines known to differ in bone structure (heavier-boned, HB, and lighter-boned, LB) were assigned to three diets (P adequate, P repletion, or P deficient). After 14d, bone marrow and intact radial bones were collected. Based on dietary treatment, we observed differences between these lines in growth rate, bone integrity, and gene expression within bone marrow. In HB, but not LB pigs, the P deficient diet caused a decrease in weight gain (P<0.01). For both lines, P deficiency caused a reduction in radial bone strength (P<0.01), but HB P deficient animals had greater (P<0.10) bone integrity than LB P deficient pigs. In HB, but not LB pigs, dietary treatment affected the expression of CALCR (P<0.05), VDR (P<0.04), IGFI (P<0.11), and IGFBP3 (P<0.06). There was also a trend of increased IL6, TFIIB, and SOX9 expression with P deficiency in HB, but not LB, pigs. A trend of increased expression of OXTR was seen in P deficient animals in both genetic backgrounds. Expression of RAN KL, BG LAP, 0 PG, ARAF I, and JG FBP 5 was not affected by genetic background or diet. These data suggest that HB pigs were more responsive to dietary P restriction than LB pigs. Differences in growth rate, bone integrity, and gene expression within the bone marrow suggest a difference in the homeorhetic control of P utilization between these genetic lines. Linkage analysis of the VDR HpyCH4IV polymorphism in the Berkshire x Yorkshire intercross family mapped VDR to pig chromosome Sq. The genes that were differentially expressed based on genetic background and dietary treatment interaction were then examined for single nucleotide polymorphisms (SNPs). We identified SNPs in CALCR, VDR, JGFBP3, and OXTR genes, and PCR restriction fragment length

Abstract The Delphi Technique was used to identify those conditions which are most likely to encourage full participation in non‐formal education (NFE) programmes. A panel of experts in international development education was selected for the study. Panelists were asked to rate the importance of individual conditions drawn from the programme development, economics, sociological, political and psychological literature. These experts were also encouraged to identify further critical conditions. The results of the study indicate that the participants believed that if we are to attract full participation at the village level in NFE programmes, then it is essential that we 1. adopt a user‐centred approach which truly identifies local needs, 2. provide a clear linkage between participation and the fulfilment of personal needs, and 3. use outside experts as facilitators rather than dictators. Of the five groups of conditions reviewed political conditions were seen as being of primary importance.

This study aims to clarify the provisions of the liability of the moral person in the electoral publicity crimes in the Jordanian House of Representatives Electoral Law No. 6 of 2016, and to clarify the problems of implementing the criminal sentences issued against him. The study indicated that the Jordanian legislator did not stipulate any substantive or procedural rules concerning the penal liability of the moral person for the electoral crimes in the House of Representatives Electoral Law No. 6 of 2016 relying on the general rule stated in Article 74 of the Jordanian Penal Code No. 16 of the year 1960 and its amendments, which established the penal liability of the private moral persons and excluded the public moral persons i.e. the governmental department or official or public institution. The study concluded that the liability of the moral person in the electoral publicity crimes is subject to the general provisions included in the general section of the Penal Code and the Code of Criminal Procedure concerning the general procedural rules applicable to the natural person that are in line with the nature of the moral person, which constitutes a legislative deficiency as its adoption is not sufficient to establish of the penal liability of the moral person in the electoral publicity crimes, without creating an integral procedural system for prosecuting the moral person when he commits the electoral publicity crimes.


This study shows that phase shifting using a single reference beam enables determination of fractional fringe orders at any point on the test surface. When applied to the assessment fo the detected unbond, this simple technique gives a more accurate estimation of the unbond depth than conventional holography


The Vehicle Routing Problem with Time Windows (VRPTW) is an important problem in logistics. The problem is to serve a number of customers at minimum cost without violating the customers' time window constraints and the vehicle capacity constraint. The m-VRPTW is a variant of the VRPTW in which a limited number of vehicles is available. A feasible solution to m-VRPTW may contain some unserved customers due to the insufficiency of vehicles. The primary objective of m-VRPTW is to maximize the number of customers served. In this paper, we propose a two-stage algorithm for the m-VRPTW. The algorithm first maximizes the number of customers served with an Ejection Pool to hold temporarily unserved customers. Then it minimizes the total travel distance using a multi-start iterated hill-climbing algorithm with classical and new operators including Generalized Ejection Chains. The experimental results showed consistently good performance of the algorithm when compared with other methods.


We consider the 1d Schr\"odinger operators with random decaying potentials where the spectrum is pure point(sub-critical case). We show that the point process composed of the rescaled eivenvalues, together with those zero points of the corresponding eigenfunctions, converges to the Poisson process.


Maize is one of the most important staple foods and the basis of diet for Ethiopian's. The present study was conducted to compare the effectiveness of traditional (Gombisa and Sack) and of hermetic bag storage methods concerning quantitative and qualitative losses after 0, 2, 4 and 6 months of storage. The design was arranged in 3x4 factorial fashions. Quality of maize grains (variety: Bako Hybrid-661) stored in the three storage types (Gombisa, Sack and Hermetic Bag) for 6 months studied was in Bako, Ethiopia. Nutritional quality values (total protein, total fat, total fiber, total ash, and utilizable carbohydrate) the samples were analyzed for grain quality deterioration over time. Crude protein, Crude fat, Crude fiber, Crude Ash and total carbohydrate contents was influenced significantly (P<0.05) by storage type in Gombisa. Total protein, total fat, total fiber, total Ash and utilizable carbohydrate contents was significantly (p<0.05) influenced by storage periods. Initially total protein was high 8.9% and dropped significantly to 6.2% in Gombisa in six months of storage periods. Maximum value of total ash was recorded at initial and dropped significantly to 1.1% at the end of six months. The study shows maize grains quality losses in Gombisa and Sack might be due to relative humidity, temperature, moisture content were suitable for storage insects infestation and fungal contamination. As a result of this research, the Hermetic bag was determined to be more appropriate for maintaining grain quality for longer.


Designing a chip set for a new processor architecture like the IA-64 requires handling multiple aspects. They include implementing the processor interface; providing sufficient I/O bandwidth for servers; supporting accelerated graphics port (AGP) graphics; and providing sufficient memory bandwidth for the processor, I/O, and graphics. This article provides an introduction to the memory, I/O, and graphics subsystems of Intel's Itanium processor chip set and discusses several aspects of the processor bus.


In MANETs, majority of performance studies are carried out via simulations, where node mobility and radio propagation models play a crucial role. However, popular simulation tools, like NS-2 and GloMoSim, use simplistic random mobility patterns and free space radio propagation models. Such simplification ignores many crucial details in environment where movements are not random and obstacles are common. To have a better understanding of MANET protocols, there is a need for a tool that can generate more realistic mobility scenarios and provide better radio propagation model. This paper presents EGRESS, which is built on top of NS-2 and consists of two major components: SGT and ORPM. SGT is a tool that generates node movements in an urban environment with buildings and pathways. ORPM is an obstructive radio propagation model, which enhances the existing radio models in NS-2 by taking into account obstacles in a 3D environment. We believe EGRESS is the first open source tool that provides such integrated and more realistic features for simulating urban environment. Our simulation results show that using more realistic scenarios can have a significant impact on network topology and performance of routing protocols


A new formula has been derived to describe the energy spectrum of sputtered atoms from a target material bombarded by light ions. We assume that sputtered atoms bombarded by low-energy light ions are mainly primary knock-on atoms which are created by large-angle backscattered light ions. The escape processes of recoil atoms are estimated on the basis of the Falcone-Sigmund model. The new formula has the dependence on the incident energy of a projectile. We have compared the new formula with simulation results calculated with ACAT code for a Fe target material bombarded by 50 eV, 100 eV and 500 eV D + ions. Good agreements are found for 50 eV and100 eV D + ions.


Reproducibility—the ability of independent researchers to obtain the same (or similar) results when repeating an experiment or test—is one of the hallmarks of good science (Popper 1959). Reproducib...


Introduction: Lymphangioma are rare vascular malformation that results from maldevelopment of primitive lymphatic sacs. They are most frequently found in the neck and axilla, while intra-abdominal and mediastinal lymphangiomas are uncommon. Atypical site of cystic hygroma in pediatric age group are usually difficult to diagnose clinically but can be diagnosed easily by ultrasound. The aim of the study was to evaluate the result of the intralesional bleomycin for macrocystic lymphatic malformation (LM) presenting at atypical site Material and Method: All patients of LM of other than head& neck, axilla and abdomen presenting in pediatric age group were included in the study. Mainstay of diagnosis was ultrasound and was supplemented by CT scan wherever required. All patients were managed with intralesional bleomycin (ILB) and surgical excision was done only if primary therapy failed. Result: Total 15 cases of LM presenting at atypical sites were included in the study. Series include two case of cystic hygroma of breast, 4 cases of cystic hygroma of anterior chest wall, two case of substernal LM, three cases of LM of parotid gland, one case of inguinal region cystic hygroma and 4 cases involving submandicular area. Complete resolution was observed in 13 out of 15 cases, and two cases had less than 50% reduction in size and were managed with surgical excision after second session of ILB. Conclusion: Aqueous Intralesional bleomycin is a cost effective alternative to surgery even at rare sites of LM which provide better aesthetic outcome, and avoids complication associated with surgery.

Multirate fast-convolution (FC) processing can be used for realizing low-complexity filter banks (FBs) and transmultiplexers (TMUXs). The main advantage of the FC-based realizations when compared with the polyphase FBs is the increased configurability, that is, the number of subchannels, their bandwidths, and the center frequencies can be adjusted independently. In general, FC-based FBs are linear periodically shift-variant systems. In this brief, novel matrix representations for the FC synthesis and analysis FBs are first derived. These representations give all the shift-variant impulse responses of the FC-based FBs. Then the TMUX optimization criteria are expressed using these representations. Two examples are included to demonstrate the performance of the optimized designs as well as to illustrate the flexibility of the resulting FC-based TMUXs.


FOR MORE THAN A DECADE, advocates of precision air weapons have argued that wars can be won by selectively taking out an enemy's leaders, its communication systems, and the economic infrastructure of its major cities. Before the Persian GulfWar, Air Force Chiefof Staff General Michael Dugan promised to end the war in days by targeting Saddam Hussein directly. Later, in Kosovo, General Michael Short, commander of allied air forces in Europe, ordered air power to "go for the head of the snake." And last year, in the Iraq war, Secretary of Defense Donald Rumsfeld sponsored a "shock and awe" air campaign against the Iraqi leadership. Whether it helps kill enemy leaders, isolate them from their troops, or make them vulnerable to overthrow by local groups, precision air power is advertised as a force that can win wars on its own. Decapitating the enemy has a seductive logic. It exploits the United States' advantage in precision air power; it promises to win wars in just days, with few casualties among friendly forces and enemy civilians; and it delays committing large numbers of ground troops until they can be welcomed as liberators rather than as conquerors. But decapitation strategies have never been effective, and the advent of precision air weaponry has not made them any more so. No doubt, precision technology has increased the accuracy of bombing. Today, 70 to 8o percent of guided munitions fall within


The output elasticities of irrigation water are high inelastic for every crop, indicating that reductions in water supply would have relatively small effects on crop production. This article reports estimates of Cobb-Douglas and quadratic production functions for 13 irrigated crops in the 17 Western States Returns to scale, the output elasticity of irrigation water, and the marginal rate of substitution between water and land are estimated for each crop J-tests, used to test statistically which, if either, functional form is a correct specification, do not reject the Cobb-Douglas specification for four crops (barley, grain sorghum, potatoes, and rice) and do not reject the quadratic specification for three crops (cotton, dry beans, and potatoes).


Awarming climate leads to increases in evaporation and, therefore, increases in precipitation, as is evident by the overall trends experienced in the United States. Precipitation has increased at an average rate of 0.2 inches per decade, and trends vary geographically, with some areas experiencing a 30% increase in precipitation since 1901 (Figure 1) (1). In the context of climate change, more frequent and more intense precipitation events are anticipated. Therefore, defining the impact of precipitation on respiratory health is imperative to protect patients and communities. In this issue of the Journal, Nassikas and colleagues (pp. 698–704), in the Project Viva prebirth cohort study, demonstrate an association between increased precipitation and airway inflammation (2). Adolescents with asthma and those sensitized to outdoor allergens had an exaggerated response, suggesting that these groups are more susceptible to increases in precipitation. Precipitation comes in many forms, and much of the increase seen in the United States is due to extreme single-day precipitation events.When looking over the past century, 9 of the top 10years for extreme one-day precipitation events have occurred since 1996 (3). Pollen and aeroallergens are also increasing in the settings of more atmospheric carbon dioxide and longer growing seasons. Ragweed, an aeroallergen commonly attributed to asthma exacerbations, is also increasing in the United States. The Environmental Protection Agency reported an increased ragweed pollen season by 6–21days in 10 of 11 pollen stations from a study looking at central United States (4). Pollen has been identified as a key trigger in thunderstorm asthma—a phenomenon defined as the occurrence of asthma attacks occurring immediately after a thunderstorm (5). Extreme health consequences have been demonstrated in epidemic events, as occurred inMelbourne, Australia, in 2016, which resulted in 3,400 excess asthma emergency visits shortly after a thunderstorm (6). In their study in this issue of the Journal, Nassikas and colleagues take a broader view to deepen our understanding beyond specific storms and asthma exacerbations by studying airway inflammation and lung function and considering the temporality of respiratory responses to increases in precipitation. Nassikas and colleagues studied 1,019 adolescent patients from a prospective prebirth cohort who had routine fractional exhaled nitric oxide (FENO) testing, a validated marker of type 2 inflammation, and spirometry between 11 and 17 years of age. Twenty-six percent of the cohort had asthma, and 58% of those tested were sensitized to aeroallergens. Regression models were used to evaluate the association between moving averages of precipitation over 1, 2, 3, and 7days and FENO and lung function. Ultimately, after controlling for pollution and humidity, they found that, across all study participants, a 2-mm increase in precipitation over the 7-day moving average resulted in 4.0% higher FENO and that the relationship was exaggerated in the asthma group with 5.8% higher FENO for a 2-mm increase in precipitation in a 3-day moving average. In addition, the group with asthma had significant associations between precipitation and lung function, with a 12-ml lower forced expiratory volume in 1 second and a 16-ml lower forced vital capacity per 2-mm increase in precipitation over a 2-day moving average. Among those sensitized to outdoor allergens, the relationship between precipitation and FENO was amplified compared with that for individuals who were nonsensitized. The finding that individuals sensitized to outdoor allergens and those with asthma have a significant increase in airway inflammation after precipitation events is consistent with the risk factors previously reported as associated with thunderstorm asthma. D'Amato and colleagues reviewed the evidence and reported in 2018 that patients with 1) allergic rhinitis, 2) those with open-air exposure who were not taking an inhaled corticosteroid (asthmatic or not), or 3) those with a sensitization to outdoor allergens were the most likely to require medical care after a thunderstorm (7). However, not all thunderstorms lead to asthma exacerbations. Different meteorological and air quality conditions exist in thunderstorms, and these suggest pathways that may drive inflammation and changes in lung function. Most thunderstorms provoking asthma have outflow boundaries, air that flows outward in front of a storm and can sweep up dust, dirt, pollen, grasses, and fungi (8). The contents of the outflows may provoke sensitized or susceptible individuals. Additionally, storms associated with cold fronts and outflow boundaries may also impact airways because of temperature. In 1996, Celenza and colleagues demonstrated that rapid drops in temperature, or cold fronts, are associated with thunderstorm asthma epidemics; however, not all of these epidemics have cold fronts: Studies that only examine average temperature may not detect the impact of temperature swings (9). Prior work suggests that large temperature swings—which can be captured as diurnal temperature range, or the difference between the maximum and minimum daily temperature—are associated This article is open access and distributed under the terms of the Creative Commons Attribution Non-Commercial No Derivatives License 4.0.

The aerodynamic performance results indicate that the fan adiabatic efficiency was highest with nominal tip clearance (about 91.8% at design speed) and decreased as fan tip clearance increased. Differences in fan efficiency between tip clearance configurations was small below 77.5% fan design speed, about 0.5% maximum, and got larger as fan speed increased, to around 1% maximum at 100% fan design speed. The decreases in efficiency are due to a lower blade loading and higher temperature rise over the outer 20% of the blade span; the mechanism is the tip leakage flow from pressure to suction surface of the fan blade, which increases as the fan tip gap increases. Farfield acoustic results show that changes in the noise level are primarily aft-radiating and are on the order of 1 to 5 dB in fan broadband noise level as measured for the rotor-alone configuration (which had no stators). There were very small changes in noise level with tip clearance for the 54-vane Baseline Outlet Guide Vane configuration. Small changes in noise were also seen for the other two Outlet Guide Vane configurations tested - the 26-vane radial Low Count Outlet Guide Vanes and the 26-vane aft swept Low Noise Outlet Guide Vanes. The rotor alone acoustic results suggest that tip clearance changes induce broadband noise changes at the fan tip, but that the noise differences are masked by the rotor wake/stator interaction noise generated with the Outlet Guide Vanes installed. The magnitude of the rotor/stator interaction tones showed small increases with increasing fan tip gap at fan speeds below transonic, indicating slightly stronger interactions with the larger tip vortex wakes that formed with larger tip gaps. The broadband levels, for the most part, only showed the effect of Outlet Guide Vane geometry on the magnitude of the noise as the tip gap changed. The Laser Doppler Velocimetry flow field results show that the flow downstream of the tip of the blades changes very little with changes in the tip clearance when operating at the approach condition. At both the cut-back and take-off speeds, significant changes in the tip flow occur with changes in the tip clearance. Since these changes in the tip flow are not *

Wear and degradation as exhibited by degassing of three commercially available perfluoroalkylpolyethers, A, straight chain with acetal linkage (OCF2CF2)p(OCF2)q;B, straight chain without acetal linkage (CF2CF2CF2O)n; C, branched chain (CFCF3CF2O)m, were evaluated at 0.025 mis under 1 to 300 N at 10−5 Pa in a four-ball configuration using 440C and Si3N4 balls, Φ:6.35 mm, as test specimens. A quadrupole mass spectrometer having a mass range of 1 to 200 amu was employed to analyze gaseous products released from the sliding surfaces. Disregarding the gas released, Oil C showed slightly better wear characteristics than B, but far better than A when tested with a 440C ball on 440C balls. Taking gas evolution into account, Oil B carried the highest load; the initial degassing was detected at the Hertzian pressure of 1 GPa for A, 2 GPa for B, and 1.75 GPa for C when using 440C balls, and at 1.5 GPa for A and 2.75 GPa for C when using Si3N4 balls. Oil B evaluated with Si3N4 balls did not evolve gases even at 2.75 ...


the statement that 'the experience of the nameless mystery as both origin and goal is the a priori condition of all categorial knowledge . . . not merely a marginal phenomenon at the end of the road' (p. 237). It might have been better perhaps to leave it at that instead of using paradoxical language about this experience. A short piece, 'An Investigation of the Incomprehensibility of God in St Thomas Aquinas', adds the further bafflingcomplication of 'an ontological self-communication of God to the created intellect which is not the result of direct vision but its ontological condition' (p. 250). But it ends finely: 'Freedom and love can be seen as identical in origin with the intellect (given the 'ordo' between them), and the intellect only achieves its own fullness of being when in hope and love, in a freedom which properly belongs to it, it surrenders itself to incomprehensibilityas to its own beatitude'.

The current paper is a part of a master dissertation carried out at the Open University of Cyprus.
Starting from an individual to a multinational corporation level we are looking to find, understand and define
the purpose, the need and the impact of managing the impressions made. We argue that strategies may vary
regarding the type of business. We suggest that anybody has an opinion as soon as they identify the brand.
This opinion is disseminated and collectively can be seen as reputation. The progress in communication is
implying bigger social influence between the people, trends are changing fast. We are presenting different
tools to find these insights, which perform Online Reputation Management (ORM), free, paid or open
source. Using theory from social science and technological facts, we discuss possible caveats. Finally we aim
to use python scripts in order to collect, preprocess and analyze real data to see it in practice through the
prism of a real business entity.


Since Gyungan stream is included in the protected zone of the water supply source of the Metropolitan area in Korea, the water quality needs to be continuously managed. Therefore, a measure is required that can inhibit the flow of water pollutant into the water body and facilitate the ecological restoration of riparian vegetation. A field survey was conducted on the hydrological characteristics of the landscape elements established on the downstream catchment of the Gyungan stream, the result of which showed that the paddy field and urbanized area can be regarded as point pollution sources. The upland field can be regarded as a non-point pollution source. In order to improve the water quality in the Paldang lake, we first recommended creating a riparian vegetation belt. We also suggested introducing a treatment wetland and an artificial plant island to places in which the creation of a riparian vegetation belt is not ensured. We recommend creating a treatment wetland equipped with diverse functional groups. For creating the plant island, we recommend Zizania latifolia and Typha orientalis , which showed the highest productivity among aquatic plants. The former could be introduced around the outlet of a paddy field and the estuary of tributaries, while the latter could be introduced to a water body directly sourced from mountainous land.


In order to further improve the safety performance of lithium ion batteries,cyclohexylbenzene(CHB)was investigated to be an overcharge protection additive for non-aqueous liquid electrolyte in lithium ion batteries.Proved by overcharge of batteries,cyclic voltammetry tests and battery power capacity measurements in this research,certain conclusions were obtained.When the external potential ranges from 4.3 V to 5 V,CHB(2.5% or 5% by mass)in the system of electrolyte 1 mol·L-1LiPF6/EC+DEC+DMC(1∶1∶1 by volume)can produce the conductive polymer film,creating the short-circuit between the positive and negative electrodes and causing self-discharge.Therefore the cell's potential can be controlled between 4.5-4.8 V,and the lithium ion batteries can be much safer when overcharged.Meanwhile,during the normal charge-discharge process of the battery system,the addition of the proper weight percentage of CHB does not have negative effect on the capacity character of lithium-ion battery.All these advantages promise CHB to be an ideal overcharge protection additive in lithium ion batteries.
