Air Pollution Tolerance Index (APTI) is an important tool to screen out plants, based on their tolerance or sensitivity level to different air pollutants. The present study has been conducted to evaluate APTI of four different plant species around polluted and unpolluted industrial site in Sfax, Tunisia. In order to determine the susceptibility level of the selected plant species, it has used four physiological and biochemical parameters like leaf relative water content, ascorbic acid content, chlorophyll content, and leaf pH to compute the APTI values. The results of the study reveal that among the four studied plant species, Olea europaea (APTI = 20.09) and Phoenix dactylifera (APTI = 17.10) are the most tolerant species, whereas Ficus carica (APTI = 8.87) and Morus alba (APTI = 7.49) are the most sensitive ones. The present study suggests that the most tolerant species, i.e., olive and date palm, can be planted in polluted sites for both air pollution abatement and aesthetic improvement. While, the sensitive species, namely common figand white Mulberry, help indicating air pollution and should be utilized as bio-indicators.


ABSTRACT In sub-Saharan Africa, the high cost of synthetic fertilisers and the need to produce higher quality crops have necessitated research on alternative nutrient inputs. The effects of soil amendments with poultry manure + Tithonia diversifolia compost at 10, 20, 30 t ha−1 (PMC10, PMC20, PMC30), cow dung + T. diversifolia compost at 10, 20, and 30 t ha−1 (CDC10, CDC20, CDC30) poultry manure (PM) at 10 t ha−1 (PM10), cow dung (CD) at 15 t ha−1 (CD15), and T. diversifolia (TT) at 10 t ha−1 (TT10) on growth, yield and quality of okra was investigated in a field trial in Abeokuta, Nigeria in 2011 and 2013. Treatments were arranged using a randomised block design with three replicates. The highest numbers of leaves per plant (14) were recorded in the treatments with PMC20 and PMC30 in 2011 and 2013, respectively. Application of PMC20 significantly reduced the number of days to 50% flowering compared with the control. In 2011, the potassium concentration in okra leaves and the nitrogen concentration in okra pods were highest for plants grown in soil amended with PMC30. The uptake of phosphorus was highest for plants treated with CDC20 (1.26 g m−2) and with TT10 (0.65 g m−2) in 2011 and 2013, respectively. All treatments resulted in significant increases in the yield of pods compared with the control. PM and CD used either in their original forms or composted with Tithonia diversifolia improved the growth and yield of the okra and the nutrient concentrations of the pods.

The purpose of this empirical study was to investigate if stress exists among nurses, and if it exists how do they experience it and how do they cope whit it. The nurses also got to define the word stress. Karasek and Theorells demandcontrollmodell were used as a theoretical framework. The result of the study answers our research questions and gives us a good insight how the nurses experience stress and how they cope with it. The result shows that 56 of 60 nurses indicated that they experience medium to high level of stress a couple of days a week or more often and that it affects their work. Since not many superiors offers their nurses any stress coping many nurses have to handle their stress on their own. Most of them define stress as something negative were they no longer have any control over the situation.


The crest of a steep, symmetric gravity wave is shown to be closely approximated by the expression \[ x+iy = \frac{\alpha +\gamma i\chi}{(\beta + i\chi)^{\frac{1}{3}}}, \] where x, y are co-ordinates in the vertical plane, χ is the complex velocity potential and α, β, γ are certain constants. This expression is asymptotically correct both for small and for large values of |χ|; and the free surface agrees with the exact profile calculated by Longuet-Higgins & Fox (1977) everywhere to within 1·5 per cent. The pressure at the surface is constant to within 5 per cent.


The reconstruction and monitoring of visibility over marine environments is critically important because of a lack of observations. To travel safely in marine environments, a high quality of visibility data is needed to evaluate navigation risk. Currently, although visibility is available through numerical weather prediction models as well as ground and spaceborne remote sensing platforms and ship measurements, issues still exist over the remote marine environments and northern latitudes. To improve visibility prediction and reduce navigational risks, gridded visibility data based on artificial neural network analysis can be used over marine environments, and the problem can be regarded as an air quality prediction problem based on machine learning algorithms. This new method based on artificial intelligence techniques developed here is tested over the Indian Ocean. The mean error of the inferred visibility from the artificial neural network analysis is found to be less than 8.0%. The results suggested that satellite-based optical thickness and numerical model-based reanalysis data can be used to infer gridded visibility values based on artificial neural network analysis, and that could help us reconstruct and monitor surface gridded visibility values over marine and remote environments.


AIM
To retrospectively investigate the risk factors and time to occurrence of genitourinary (GU) toxicity after radiotherapy for localized prostate cancer.

PATIENTS AND METHODS
The study included 320 patients. The radiotherapy planning target volume encompassed the prostate with a 1-cm margin in the transverse plane and a 1-cm margin (Group A) or a 1.5-cm margin (Group B) in the longitudinal plane. Incidence rates, risk factors and time to occurrence of GU toxicity were evaluated.

RESULTS
After a median follow-up of 38.2 months, the rate of late grade 2-3 GU toxicity was 5.9% and the median interval was 18.3 months. The wider longitudinal margin was the single significant independent factor. The 2-year cumulative incidence rates of late grade ≥2 GU toxicity were 2.8% and 7.5% in Group A and B patients.

CONCLUSION
A wider radiotherapy margin increased the risk of GU toxicity and led to earlier occurrence.


The research and study of medieval Hebrew manuscript fragments has a long tradition in the Czech lands. The leading figures of the Czech Enlightenment, Josef Dobrovský and Fortunat Durych, devoted attention to such fragments within the context of Bible Criticism and worked closely in this field with German and Italian Hebraists. At the beginning of 2000, work began at the Jewish Museum in Prague under the supervision of Olga Sixtova on preparations for a comprehensive catalogue of Hebrew manuscripts in the collections of archives, libraries and museums in the Czech Republic. It was not until the beginning of 2004 that work began on the systematic research into Hebrew manuscript fragments. So far, 396 fragments have been found as part of the research; 218 of these were found in Prague libraries and archives. Keywords: Czech Republic; medieval Hebrew manuscript fragments


Iron oxides currently attract considerable attention due to their potential applications in the fields of lithiumion batteries, bio-medical sensors, and hyperthermia therapy materials. Magnetite (Fe3O4) is a particularly interesting research target due to its low cost, good biocompatibility, outstanding stability in physiological conditions. Hydrothermal synthesis is one of several liquid-phase synthesis methods with water or an aqueous solution under high pressure and high temperature. This paper reports the growth of magnetic Fe3O4 particles from iron powder (spherical, <10 μm) through an alkaline hydrothermal process under the following conditions: (1) Different KOH molar concentrations and (2) different synthesis time for each KOH molar concentrations. The optimal condition for the synthesis of Fe3O4 using Fe powders is hydrothermal oxidation with 6.25 M KOH for 48 h, resulting in 89.2 emu/g of saturation magnetization at room temperature. The structure and morphologies of the synthesized particles are characterized by X-ray diffraction (XRD, 2θ = 20°–80°) with Cu-kα radiation and field emission scanning electron microscopy (FE-SEM), respectively. The magnetic properties of magnetite samples are investigated using a vibrating sample magnetometer (VSM). The role of KOH in the formation of magnetite octahedron is observed.


Quantitative electroencephalography was used to determine differential neuropharmacological effects of barbiturates in chronic schizophrenic men and nonpsychotic male volunteers. The effects of oral pentobarbital and intravenous thiopental were compared in the two groups. The schizophrenic patients were relatively refractory to the sleep‐inducing effect ot the pentobarbital and showed attenuated responses to this drug in their electroencephalograms in comparison with the nonpsychotic subjects. The patients also showed quantitative electroencephalographic changes consistent with the clinical definition of greater !activation" after the thiopental. Both of these findings suggest that these patients, at least in the experimental setting, tend to be more !alerted" or !overstimulated" than the nonpsychotic subjects.


ABSTRACT Endocrine-disrupting compounds (EDCs) areconsidered as an emerging group of trace contaminants detected in the environment worldwide. Bisphenol A (BPA) is one of these toxic pollutants that arereleased mainlyfrom industries and can cause serious health and environmental problems.Thus, in this study, titanium dioxide and zirconium dioxide particles were deposited on pumice, and then the efficiencies of O3/nTiO2/H2O2 and O3/nZrO2/H2O2on BPA removal were studied under different operational conditions. The results showed thatBPA removal efficiency was increased by increasing the pH, contact time, catalyst dosage and concentration of H2O2 and maximum removal efficiency for both studied processes was ≈100% at optimum conditions, i.e. pH of 11, are action time of 30 min, catalyst dosages of 4 g/L for O3/nTiO2/H2O2 and 12 g/L for O3/nZrO2/H2O2, H2O2 concentration of 2 mmol/L for O3/nZrO2/H2O2and 5 mmol/L for O3/nTiO2/H2O2, and initial BPA concentrations of 20 mg/L.Increasing the catalyst dose to a certain level, increases the production of hydroxyl radicals, which, in turn, increases the degradation of BPA. The pumice XRD pattern coated with TiO2 and ZrO2 nanoparticles shows the main and derivative elements of pumice, including pyroxene, magnetite feldspar mica, and SiO2.FTIR spectra for TiO2 and ZrO2 nanoparticles showed that the peaks at 455 and 457 cm−1 are related to the C-N-C bands in amine functional groups. We found that the studied integrated catalytic ozonation processes (COP)have high efficiency in removing BPA, therefore it can be used as asuitable and effective methods for removal of such organic pollutants from aqueous solution.


This paper is a progress report of the first phase of a project which essentially seeks to replicate previous studies using the successful/unsuccessful design in an attempt to: (1) corroborate the surface/deep structure cenclusion which has become an essential component of an understanding of problem-solving; (2) examine more closely the nature of the categorization procedure and how it is applied; (3) reexamine the similarity of keywords identified by subjects; and (4) extend the research into another content area, enhancing the generalizability of the conclusions. Included are results of a pilot study of how geneticists i.e. biologists categorize genetics problems. Findings (based on five faculty responses) show that: biology faculty members apparently have a detailed mental organizational structure for genetics problems; genetics problems are apparently mentally organized by these individuals in a hierarchical system; the self-report of at least one subject suggests that this organization plays a signficant role in problem-solving; genetics principles used by faculty subjects to organize genetics problems appear to be very similar in most cases; the organizations produced were based on "deep structure"; and the keywords identified by subjects are closely tied to the organization scheme being used.

At the present time the Department of the Environment recommendation for the green light interval is 30 or 40 seconds, this time remaining fixed for all flow rates. A computer simulation study is described, which was carried out to determine whether or not there was a case for varying this signal setting according to the different levels of pedestrian and vehicle flows occurring during the day. Graphs are presented of total vehicle flow rate (veh/h) against total pedestrian flow rate (ped/h) for a range of conditions. From this work it is suggested that there is a case to be made for designing a pelican crossing to be sensitive to the size of pedestrian and vehicle flow rates. However, the curves indicate that the results are not highly dependent on pedestrian flow rates, and that as a compromise measure, it would be possible to use vehicle flow rate alone, as at most traffic signal situations, in order to vary the length of the green light interval. /TRRL/


In this work we show that the classification performance of high-dimensional structural MRI data with only a small set of training examples is improved by the usage of dimension reduction methods. We assessed two different dimension reduction variants: feature selection by ANOVA F-test and feature transformation by PCA. On the reduced datasets, we applied common learning algorithms using 5-fold cross-validation. Training, tuning of the hyperparameters, as well as the performance evaluation of the classifiers was conducted using two different performance measures: Accuracy, and Receiver Operating Characteristic curve (AUC). Our hypothesis is supported by experimental results.


Reported speech is a crucial part of news articles, which frequently rely on quotations to report on the perspectives and opinions of direct participants in the narrated events. The ability to accurately extract and organize these quotations is highly relevant for text mining applications aiming to reduce human intervention in media monitoring, help journalists in fact-checking, or aid media scholars and general users to browse the news. Several previous studies have addressed the extraction of reported speech from news articles, although often addressing only direct quotations and/or using relatively simple methods relying heavily on hand-crafted features. This article extends these previous studies in several directions, evaluating the application of modern deep learning methods for quotation extraction (i.e., for delimiting occurrences of direct, indirect, and mixed quotations), attribution (i.e., for assigning quotations to the corresponding authors, as mentioned in the surrounding text), and classification (i.e., for assigning quotations to numerical scores encoding emotional valence and intensity). Particularly innovative aspects include the use of Nested-LSTMs, as opposed to more common RNNs, or the association of quotations to emotional valence and intensity. Experimental results show that relatively simple neural architectures, based on RNNs, can achieve very good results in all three aforementioned tasks, outperforming previously reported results.


The trouble with Outcome-Based education is that it is an idea ahead of public education's ability t o deliver. A research-derived knowledge base for implementing OBE remains lacking. Conversely, the philosophy now underlying OBE is shown to be surreptitiously loaded with a value orientation previously rejected by a sizeable proportion of the public While originally intended to be a neutral and objective approach to educational accountability, OBE is now a vehicle that promotes the mandatory learning of specific values-oriented content. Highly amenable to biblical teachings, OBE is regrettably an anathema to many Christian educators.

Higher-education institutions are seeing an increasing interest in entrepreneurship education across the disciplines, engineering programs included. With a parallel growing emphasis on work-integrated learning opportunities for students, a unique opportunity is presented with an Entrepreneurial Work-Integrated Learning (EWIL) pedagogy, where entrepreneurship education is delivered through the application of work-integrated learning pedagogy. Supervised Entrepreneurial Work-Integrated Learning (sEWIL) is a particular modality of EWIL, where engineering students learn about entrepreneurship through participation in a start-up working environment, where students directly observe and participate in the entrepreneurial working environment. sEWIL offers students an authentic real-world learning environment where tacit entrepreneurial knowledge is acquired, knowledge that cannot be taught through in-class traditional teaching practices. Through purposeful reflection, engineering students are confronted with the question of their professional and personal identities and their compatibility to the start-up working environment, whether as entrepreneurs or as working engineering professionals. The sEWIL pedagogy is presented and discussed through a work-integrated learning quality framework.


Rank Pneumo has worked with the Center of Optics Manufacturing to design a multiple-axis flexible machining center for spherical lens fabrication. The OPTICAM/SM prototype machine has been developed in cooperation with the Center's Manufacturing Advisory Board. The SM will generate, fine grind, pre-polish, and center a spherical lens surface in one setup sequence. Unique features of the design incorporate machine resident metrology to provide RQM (Real-time Quality Management) and closed-loop feedback control that corrects for lens thickness, diameter, and centering error. SPC (Statistical Process Control) software can compensate for process drift and QA data collection is provided without additional labor.


Industry interest of itaconate Itaconic acid is well known as a precursor for polymer synthesis and has been involved in industrial processes for decades. Itaconate was first identified in 1836 as a molecular product of citric acid distillation. In 1931, it was reported that itaconate could be synthesized in vivo by an Aspergillus species (subsequently named Aspergillus itaconcus) isolated from dried salted plums. This has spurred the development of emerging metabolic engineering strategies and process optimization technologies to enhance itaconic acid production. Today, itaconic acid has a huge world market and feeds into the preparation of industrial polymers and bioactive compounds in the personal care, agriculture, pharmaceutical, and medicine sectors. Research into more efficient methods of biomanufacturing itaconate is extremely active, because it represents a sustainable alternative to traditional crude oil- based polymers.

The article discusses the shortcomings of EU policy regarding cross-border asset recovery. The identified problem is a disjointed approach to the overlapping objectives of criminal proceedings: gathering evidence and securing assets for future confiscation. In the current EU legal framework, the process of recovery of assets, understood as a sequence of functionally related activities, lacks the continuity necessary to be effective. EU cross-border cooperation instruments in criminal matters do not meet the needs of this process, as they relate to separate investigative measures. Problems in this field have been indirectly reflected in the practice of Eurojust and the ejn. The article proposes a change in the perception of the initial phase of the asset recovery process, where the objectives of identifying and locating financial assets are combined with their provisional securing. This takes place under one mechanism of cross-border cooperation (an eio), prior to issuing a regular freeze or seizure order.

In this paper, global synchronization in arrays of coupled networks with two time-varying delay coupling is investigated. Based on Lyapunov functional, we derive two synchronization conditions of these new complex network models by using linear matrix inequality(LMI). Due to two time vary delay, it can seen clearly from our results that the synchronization states change. Finally, a numerical example is given to illustrate the theoretical results.


Weathered soils contaminated with commercial-grade Aroclor 1260 from three sites in Canada were used to investigate the polychlorinated biphenyl (PCB) phytoextraction potential of nine plant species (Festuca arundinacea, Glycine max, Medicago sativa, Phalaris arundinacea, Lolium multiflorum, Carex normalis, and three varieties of Cucurbita pepo ssp. pepo) under controlled greenhouse conditions. The soils used varied in PCB concentration (90–4200 μg/g) and total organic content (0.06–2.02%). Greenhouse experiments controlled for PCB volatilization through the use of a vented enclosure and by isolating the contaminated soils with parafilm. After 8 wks, PCB concentrations of 47–6700 μg/g were observed in root tissues. Although PCB concentrations in shoot tissues were lower (<1–470 μg/g), the absolute amounts of PCBs observed in shoot tissue were significant (1.7–290 μg) once shoot biomass was accounted for. Congener signatures indicated that tetra-to hexa-chlorobiphenyls contributed the largest proportions to shoot tissues, but hepta-to nona-chorobiphenyls were also present in measurable amounts. Overall, the results indicate that varieties of C. pepo were more effective at extracting PCBs from soil than other plants screened. The evidence suggests that this was mainly due to root uptake of PCBs and tranlocation to the shoots, rather than volatilization of PCBs from soil. All plants screened showed signs of stress in the most highly contaminated soil (4200 μg/g), but not in the two lower PCB contaminated soils (250 and 90 μg/g, respectively). No detectable decreases in soil PCB concentrations were observed in these short-term greenhouse experiments, but the results suggest that this may be achievable through multiple plantings.


Simple Summary This research evaluated the influence of dehulling on the nutritional quality of Lupinus albus seeds and the effect of their utilization in the feed of laying quails on the live performance and quality of eggs. The dehulling of lupine seeds led to an improvement in nutritional value as a result of the increase in the protein and crude fat content and the reduction in crude fiber. The use of dehulled lupine seeds in the diet of laying quails improved the performance response and quality of eggs, compared with the use of whole seeds, with the results being similar to those obtained for the quails of the control group. The presence of lupine seeds in quail feed improved the fatty acids (FA) profile of yolk lipids by increasing the polyunsaturated FA proportion to the detriment of saturated FA. The quality of the yolk fats lipidic indices became more favorable to consumer health as a result of an increase in the FA proportion, with a corresponding hypocholesterolemic effect, and also as a result of a decrease in the atherogenic and thrombogenic index values. Abstract Lupinus albus seeds from low-alkaloid varieties are a valuable alternative source of protein for reducing the dependence on soybean meal for the feeding of monogastric animals. Therefore, the aim of this research was to evaluate the dehulling influence of lupine seeds (L. albus, cv. Amiga) and the effect of their use in the laying quails feed on live performance and egg quality. A total of 200 laying quails (Coturnix japonica), with an age of 10 weeks, were randomly assigned to five experimental groups (five replicates/group). Each group was randomly assigned to one of five dietary treatments: the control group (C) diet was based on soybean meal, while the experimental groups received either 200 g/kg (WLS20) or 250 g/kg (WLS25) of whole lupine seeds in their diets, or 200 g/kg (DLS20) or 250 g/kg (DLS25) of dehulled lupine seeds in their diets. The results show that by dehulling the lupine seeds, the nutritional value of the seeds increased. The use of dehulled lupine seeds in the diet of laying quails did not affect the live performance (egg production, feed intake, feed conversion ratio), yolk cholesterol content, and physico-chemical quality indices of the eggs, compared with control. The presence of dehulled lupine seeds in the diet improved the nutritional quality of the yolk lipids because of the increase in the content of polyunsaturated fatty acids. Thus, the lipid quality indices of the yolk became more favorable to consumer health because of an increase in the h/H ratio (hypocholesterolemic/Hypercholesterolemic FA) and a decrease in the atherogenic index and thrombogenic index values. The higher content in carotenoids also contributed to the higher nutritional quality of the eggs obtained by lupine utilization. In conclusion, dehulling of lupine seeds had a positive influence on the nutritional quality of the seeds, the live performance of quails, and the quality of eggs.

That one can go no further in a search for meaning does not imply that there is no further that can be gone. The biological basis of psychoanalysis does not provide a legitimate conceptual escape hatch when one reaches personal limitations in psychological inquiry.


Adequate soil sampling with the implementation of quality control guaranties high accuracy outputs of chemical analysis of the sampled soil. Mining and Metallurgy Institute Bor, as accredited scientific institution, sampling the soil from various locations according to the previously established sampling plan and to the standards ISO 18400-101 and 180400-104. The standards define the sampling scheme. Control of compulsory monitoring of sampling quality is done by ISO 18400-106 standard. Monitoring the quality control of the sampled soil, means formation of Trip blanks and Field blanks. Developed quality control plan monitors the status of the mentioned blanks, which considers the initial chemical composition of the zero blank, its way of packing and transport to the place where sampling occurs, preservation and storage as well as chemical analysis on specific elements. During 2019, Mining and Metallurgy Institute conducted quality control after every sampling on 6 locations. Comparative chemical analysis of the blanks after the sampling, started with zero blank, resulted in non-existence of cross contamination of the sampled soil. Conclusion is that the sampling was implemented according to the given procedures and standards.


This document describes how the Federation of European Laboratory Animal Science Associations (FELASA) accreditation addresses both the Directive 2010/63/EU and the related European Commission guidance document. The four EU Functions and beyond: FELASA accredits courses that fulfil the requirements of Functions A, B, C and D as defined by EU Directive, Article 23, as well as for designated veterinarians and specialists in laboratory animal science. Modularity and mobility: Cohesive courses for Functions and for very specific topics are accredited, but flexibility and mobility are possible: a researcher can start his/her training with one FELASA accredited course and complete other modules with another. A course organizer will deliver a FELASA certificate relating to the successfully completed modules. Accreditation process: The process consists of two major steps: (1) a review of full course documentation provided by the applicant will lead, if successful, to FELASA accreditation. The course is posted on the FELASA website as 'FELASA accredited' and the course provider can deliver FELASA certificates upon successful completion of the course; (2) successful accreditation is followed by an on-site course audit. In the case of a negative outcome of the audit, FELASA accreditation is withdrawn, the course is deleted from the list of FELASA accredited courses and FELASA certificates cannot be issued. To ensure that quality is maintained, continuation of accreditation requires regular revalidation.


Teak (Tectona grandis L.f.) is a highly valued timber species raised in plantations throughout the tropics. Clonal Seed Orchards (CSO), established through grafts of selected trees are considered to be channels of genetically improved seed and starting point for domestication. India has over 1000 ha of CSOs but seed production from them has been too low to make any impact on the new plantations or advancing the breeding cycle. Genetic improvement of teak has not moved beyond the first generation orchards during the last 50 years.


We investigate the thermodynamics of the one-dimensional $t\ensuremath{-}J$ model using transfer matrix renormalization group algorithms and present results for quantities like particle number, specific heat, spin susceptibility, and compressibility. Based on these results we confirm a phase diagram consisting of a Tomonaga-Luttinger liquid (TLL) phase for small $J/t$ and a phase-separated state for $J/t$ large. Close to phase separation we find a spin-gap (Luther-Emery) phase at low densities consistent with predictions by other studies. At the supersymmetric point we compare our results with exact results from the Bethe ansatz and find excellent agreement. In particular we focus on the calculation of correlation lengths and static correlation functions and study the crossover from the nonuniversal high-$T$ lattice into the quantum critical regime. At the supersymmetric point we compare in detail with predictions by conformal field theory and TLL theory and show the importance of logarithmic corrections.


Predicting the council candidate becomes difficult due to the large number of criteria that must be known and identified. The best candidate should be chosen from among the candidates because he or she will play an important role in the organization or institution. It is critical to find the right and best candidate these days because people see and judge the outcome from the candidate in a short time with the help of social media. Perhaps the organization and institution require the best candidate criteria because they will manage and organize the community around them. This study focuses on how to prioritize council candidates using Analytic Hierarchy Process (AHP) for determine the criteria and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) for prioritize the student council candidate. This proposed framework based on MultiCriteria Decision Making (MCDM) will be used to recommend and assist students in selecting the best candidate for student council. The three criteria chosen were grade point average (GPA), Age, and Semester. Based on the results of the questionnaire and a review of the literature, these criteria were developed. The three criteria were then used to determine the most important criterion for selecting the student council. The AHP weight is used to determine and prioritize the most important criteria. TOPSIS was used to select the most qualified student council candidate. The findings show that GPA is the most important criteria in selecting the best candidate, and the TOPSIS findings support the AHP findings. Keywords—Analytic hierarchy process (AHP); technique for order of preference by similarity to ideal solution (TOPSIS); multicriteria decision making (MCDM); student council

Quantitative measurements of the absorption strength of the Si IV (1400 A) and C IV (1550 A) resonanIVe doublets have been made from OAO-2 far-ultraviolet spectra of 118 O- and B00-type stars for both doublets we note a large increase in the absorption equivalent width with luminosity classification, the increase amounting to a factor of 2 to a factor of 2 to 3 between dwarfs and supergiants. In the case of the Si IV line for stars cooler than spectral type BO.5 the observed luminoisity effect is roughly consistent with the predictions of static NLTE models. However, for the static O stars the static models predict a decrease in equivalent width with increasing luminosity. The differences between theory and observation are associated with the effects of mass outflow.The observations include a number of B stars with peculiar visual spectra.exhibits. The various peculiar stars observed appear to have normal Si IV and C IV line strengths.For a group of rapidly rotating stars the C IV line appears marginally stronger than expected on the basis of MK classification, while Si IV appears normal.

Poly(amido-amine)s (PAAs) are synthetic tert-amino polymers obtained by stepwise polyaddition of primary or secondary aliphatic amines to bis(acrylamide)s. Linear polymers are produced during the polymerisation of both primary mono(amine)s and secondary bis(amine)s. Under non-selective conditions primary bis(amine)s usually give crosslinked products upon reaction with bis(acrylamide)s, i. e., they react as tetrafunctional monomers. Furthermore, end-functionalised PAAs can be used to prepare block or graft copolymers, as well as crosslinked resins. PAAs can therefore be regarded as macromonomers as well. Generally, PAAs are soluble in water, chloroform, lower alcohols, dimethyl sulfoxide and other polar solvents (although amphoteric PAAs can only be dissolved in water). PAAs are degradable in aqueous solution by means of hydrolytic cleavage of the amidic bonds in their main chain that are activated by the tert-amino groups present in ?-position. A vast library of PAA structures has now been reported that are suitable for numerous material and biomedical applications. Here we review the synthesis, characterisation and current biomedical uses of PAAs. Their use as heavy-metal-ion-complexing polymers, and polymers for heparin neutralisation in solution, fabrication of heparin-absorbing resins and heparinisable materials is discussed. As amphoteric PAAs are biocompatible and biodegradable polymers that moreover display intelligent stealth properties, they are currently under development as PAA/anticancer conjugates and non-viral vectors for intracytoplasmic delivery. The potential of this unique chemistry is reviewed.


STANDARDIZED PATIENTS—WILL THE QUESTIONS NEVER END? Moderator: Craig Scott, PhD Using Standardized Patients to Assess Medical Students' Professionalism ´ LIE, JOHANNA SHAPIRO, JOHN BOKER, and STEPHEN RADECKI MICHAEL D. PRISLIN, DESIREE The subject of professionalism is currently engendering great inter- est within the medical education community. Concern exists that conditions within the health care delivery environment threaten established standards of professional behavior, and, perhaps more insidiously, that the medical education experience itself may be negatively influencing the development of physicians' profession- alism. 1–3 As a consequence, much energy has recently been directed toward defining competencies that reflect professionalism and in creating corresponding curricula that will foster learning in this domain. 4–6 However, having instruments that can accurately measure the attainment of professionalism remains an elusive goal. 7–9 This study examines the utility of standardized patient-based assessments of professional characteristics. Comparisons are made with other mea- sures of professionalism, such as faculty evaluation, performance on a written self-reflective exercise, and student-reported participation in community service activities. Method This study was conducted at the University of California, Irvine (UCI), College of Medicine. Participants were students completing the year two patient–doctor course during the 1999–00 academic year. This course represents the second segment of a vertically in- tegrated four-year course sequence in professional skill develop- ment. The year two segment focuses on patient–physician com- munications, physical diagnosis, and the development of basic clinical reasoning skills. Eight core clinical modules are linked to topics concurrently being taught in the year-two pathology, path- ophysiology, and pharmacology courses. Each module begins with a standardized patient interaction, followed by generation of learn- ing issues within small tutorial groups. Mid-module activities in- clude topical didactic presentations and physical diagnosis instruc- tion. Each module concludes with a wrap-up session in which the diverse learning activities are tied together through small-group dis- cussion of the original learning issues. These discussions typically feature a heavy emphasis on patient–physician communication and professional behavior. Assessments of students occurring during the course consist of a written final examination, structured written evaluations completed by the faculty group leaders, and an appraisal of clinical skills. The clinical skills appraisal for 1999–00 consisted of a three-station standardized-patient–based examination. The cases were a patient presenting with fatigue, a patient presenting with upper gastroin- testinal and chest discomfort, and a patient presenting with tran- sient neurologic deficits. The first two cases each entailed 25 minutes and the third case entailed 35 minutes of patient contact. Each station required students to perform a history and physical examination. In addition, students performed a rapid computer- based literature search following the initial encounter with the neu- rology case, written and oral clinical presentations following the fatigue case, and a written reflective essay, pertaining to students' reactions to a poem describing a 39-year-old man experiencing an acute myocardial infarction and sudden death, following the upper gastrointestinal and chest pain case. Each standardized patient en- counter included assessments of history and physical exam perfor- mance based on a checklist and assessments of communication S90 skills and professionalism using a rating scale. The rating scale for communication skills used in this study was a modification of the Communications Skills Form developed at East Tennessee State University by Forrest Lang, MD, to assess patient-centered com- munications as evaluated by standardized patients. It is based upon an instrument developed by the American Board of Internal Med- icine to assess patients' satisfaction. The rating scale includes six items relating to communication that are reported here as the cu- mulative communication score; a single item relating to overall professional competence; and a single item relating to overall stan- dardized patients' satisfaction. The professionalism scale used for this study was constructed based upon the work of Arnold and colleagues, 9 and consisted of three items: one that allowed stan- dardized patients to rate students' knowledge and competence, one that rated students' integrity, and one that rated students' altruism. Taken together, these three items are reported as the cumulative professionalism score. The specific rating scale items for commu- nication and professionalism are presented in List 1. Both the communication and the professionalism rating instru- ments used five-point Likert scales with the following specific an- chors: 5—outstanding; 4—very good; 3—good; 2—needs improve- ment; 1—marginal. Therefore, the maximum achievable scores were: cumulative communications—30 points, cumulative profes- sionalism—15 points, professional competence—5 points, and overall satisfaction—5 points. Standardized patients received de- tailed verbal and written instructions on how to complete the com- munication scale, including descriptive anchors for performance at varying levels of competence, and were observed rating perfor- mances using practice tapes before participating in the examina- tion. In terms of the specific professionalism items, the standardized patients were instructed to respond based upon their own personal perceptions of the students. Fourteen standardized patients were used during the course of the examination: seven for the fatigue case, three for the chest-discomfort case, and four for the neurology case. Faculty evaluations of students' performances during the patient– doctor II course were based on an 11-item rating scale in which one item assessed whether the student ''demonstrates professional behavior.'' This evaluation also used a five-point Likert scale in which five represented outstanding, four represented above ex- pected, three represented at expected, two represented below ex- pected, and one represented problematic performance. Hence the maximum possible score for faculty professionalism ratings was five points. Evaluating faculty received verbal instructions regarding evaluating students' performances during faculty development ses- sions. Evaluation of the professionalism item focused on students' citizenship and academic honesty, team participation, and inter- actions with standardized patients during the interview sessions. The essay was scored by one of the study's authors for emotional content and problem-solving capacity using a modification of a method described by Pennebaker and colleagues. 10 Subscale scores relating to empathy and positive coping attitudes were used as mea- sures reflecting students' expressions of professional attributes. The scores students received represented a sum of these two subscales. Students' descriptions of their participation in community ser- vice activities were elicited by means of a written survey distributed at the conclusion of the skills-appraisal exercise. Participation was scored as ''did'' or ''did not'' participate. A CADEMIC M EDICINE , V OL . 76, N O . 10 / O CTOBER S UPPLEMENT 2001


This article analyzes the behaviour of the USD/EUR exchange rate based on four major models. Using the mean absolute percent error (MAPE) as a criterion, the extended Mundell‐Fleming model performs best, followed by the PPP model using the relative PPI, the monetary model, the PPP model using the relative CPI, and the UIP model. The widely used log‐log form in the PPP model based on the relative PPI or CPI can be rejected at the 5% level. The insignificant coefficients or unexpected signs of some variables in the monetary and other models may pose some challenges in applications.


The yield stress of a magnetorheological suspension is calculated from two different approaches. The first one is based on a mesoscopic description of the structure taking only into account the shape anisotropy of the strained aggregates. The second one is based on a microscopic approach where the interparticle forces, due to the application of the field, are calculated numerically by taking into account the magnetostatics between the particles inside the aggregates. We show that the macroscopic description well applies to suspensions of nonmagnetic particles in a ferrofluid and that a layered structure, consisting of parallel slabs of magnetizable materials should have a yield stress much higher than a structure made of cylindrical aggregates. On the other hand the microscopic approach is appropriated for the description of suspensions of particles of high permeability. In this case, the yield stress is mainly determined by the rupture between pairs of particles and, consequently, it strongly increases with the angle between the line of centers of the pair undergoing the rupture and the field.

Objective:Explore the expression and its clinical significance of Eag1 potassium channel,hypoxia inducible factor-1α(HIF-1α) and vascular endothelial growth factor(VEGF) in different cervical lesion tissues. Methods:The expression of Eag1,VEGF and HIF-1α were measured in 40 cases of chronic cervicitis,40 cases of cervical intraepithelial neoplasia and 100 cases of cervical cancer by SP immunohistochemiscal method. The relationship between clinical pathological factors and cervical cancer was discussed. Results:Immunohistochemistry showed that the expressions of Eag1,HIF-1α and VEGF protein in cervical squamous cell carcinoma tissues were significantly higher than the chronic cervicitis group and the cervical intraepithelial neoplasia group( P 0. 01). The expressions of Eag1,HIF-1α and VEGF in non-keratinizing squamous cell carcinoma were higher than the keratinizing squamous cell carcinoma group( P 0. 05). The expressions of Eag1,HIF-1α and VEGF in the stage of Ⅱb and above were higher thanⅠ ~ Ⅱa period( P 0. 05). These three protein expressions in the lymph node metastasis of cervical squamous cell carcinoma were higher than which without it( P 0. 05). These three protein expressions before radiotherapy in cervical squamous cell carcinoma were higher than the post-radiotherapy group( P 0. 05). The expressions of Eag1,HIF-1α and VEGF in cervical squamous cell carcinoma were positively correlated. Conclusion:Eag1,HIF-1α and VEGF protein expressions play important roles in the development of cervical carcinoma. And they are closely related with each other. Eag1,HIF-1α and VEGF can be used to predict prognosis in cervical squamous cell carcinoma.

Based on the mass conserving boundary condition,a numerical model for cavitation of radial grooved face seals was developed.To achieve the objectives the steady,incompressible,polar coordinate Reynolds equation,including centrifugal effects and the cavitation,was discretized using the control volume finite method and solved numerically by Gauss-Siedel relaxation iterative.The block-weight approach was implemented to deal with non-coincidence of mesh and radial groove pattern in numerical method.The model was used to investigate the effects of working condition and structural parameters on cavitation area.The results indicate that rupture of oil film located where the thickness increased,and the seal dam could prevent cavitation.Cavitated area increased with the increment of rotary speed,by contraries,cavitated area decreased with the increment of groove depth.Cavitated area was dependent on hydrostatic and hydrodynamic effects in radial and circumferential direction.


Recent systematic surveys providing massive datasets of white dwarf stars show that there is still a deficit of a factor of 2.5 in the ratio of white dwarfs showing helium absorption lines to those with hydrogen absorption lines in the temperature range 30 000 K T eff < 45 000 K. Since all white dwarfs have to evolve through this temperature range along similar sequences in the color-magnitude diagram, this implies that most of the helium atmosphere white dwarfs evolve into hydrogen atmosphere hot DA stars in that temperature range and then back again to helium atmosphere white dwarfs. I describe possible scenarios for this chameleon-like disguises of white dwarfs with helium dominant atmospheres and a new kind of pulsating white dwarfs predicted to appear near the lower end of the temperature range 45 000–30 000 K from these scenarios. Recently searches have discovered a pulsating DA white dwarf, WD1017−138, in the predicted temperature range. This discovery opens the possibility of a direct test of the explanation for the deficit of helium atmosphere white dwarfs at these temperatures by asteroseismic probing of the atmospheric layers of the hot DAV stars.


Two problems concerning strain effects on isolated donor states in Si and Ge are treated. One is a modulation of the hyperfine coupling between the donor electronic and nuclear spins which gives rise to a cross relaxation rate T x -1 ( Δ m s =±1, \(\varDelta m_{I}{=}{\mp}1\)). For Raman process (double-phonon process) T x -1 is shown to depend on the temperature as T -7 . For P-donor in Si the calculated value of T x is approximately 1.5×10 4 second at T =2.16°K, which is in good agreement with the experiments of Honig and Stupp. For single-phonon process the calculation shows that T x is sensitive to static strains in the crystal, which has been confirmed in the experiments of Wilson and Feher. The other problem treated is the effects of strong external stresses on Ge donor spin-resonance lines. The electronic g -tensor, the single-phonon relaxation rates T s -1 and T x -1 , and an inhomogenous broadening effect are derived for several orientations of the stress and the magnetic field. It is shown that b...


The influence of water activity (aw) on the formation of phase bright, heat stable, and dipicoiir.ic acid-containing spores of Bacillus cereus T from stage III to stage IV forespores has beer. investigated. Decreasing aw levels reduced the rate of sporulation and the number of forespores which lysed was determined by the aw-controlling solute used. The limiting aw value for ir.e formation of mature spores was about 0·95 for glucose, sorbitol and NaCl whereas it was about 0·91 for glycerol. The development of refractility. the synthesis of dipicolinic acid, and acquisition of heat stability were affected equally by decrease in aw during sporulation. With the range of aw value where spores could be formed NaCl and glycerol had no signifcant: influence on the D value of the resulting spores whereas at all aw levels, when sorbitol was use: as the aw-controlling solute, the heat resistance was greater than in the basal medium. It Is suggested that the aw of the sporulation medium determines the quantity of spores rather than. the spore properties.


In this paper, we discuss the properties of mixed graphs whichvisualize causal relationships between the components of multivariatetime series. In these Granger-causality graphs, the vertices, representing thecomponents of the time series, are connected by arrows according to theGranger-causality relations between the variables whereas lines correspondto contemporaneous conditional association. We show that the concept ofGranger-causality graphs provides a framework for the derivation ofgeneral noncausality relations relative to reduced information sets by performingsequences of simple operations on the graphs. We briefly discussthe implications for the identification of causal relationships. Finally we provide an extension of the linear concept to strong Granger-causality.


Directional solidification of lamellar eutectic has been studied both theoretically and experimentally. This process has been modeled through comparing it with directional solidification of an array of cells in binary alloys and developing of the Saffman-Taylor viscous fin-gerinig in a Hele-Shaw cell in an unitied framework. A coupling relation among the solute diffusion, the thermal transfer and the capillary effect of the growing interface has been derived. The well known scaling law λ 2 V = const can be derived from this relation. Directional solidification of regular Al-Al 2 Cu eutectic and irregular Al-Si eutectic has been investigated experimentally, the coupling relation has been verified. The solidifying interface profile and thermal transfer effect of solidification have also been discussed.


Abstract BACKGROUND Diffuse intrinsic pontine glioma (DIPG) constitutes 80% of pediatric brain stem tumors with a median survival of 12 months. The PI3K/AKT/mTOR pathway is a key oncogenic driver of this tumor. Targeting the chromatin dysregulation through HDAC inhibition, demonstrated benefit in vivo and vitro studies. We completed the first study as a multi-targeted therapy using SAHA and temsirolimus in pediatric DIPG. METHODS After receiving institutional IRB approval, we enrolled 6 patients on this phase I study using a 3 + 3 statistical design. Patients were divided into stratum 1 and stratum 2, based on newly diagnosed or relapsed DIPG respectively. Stratum I patients received radiation therapy concurrently with vorinostat, followed by maintenance therapy with vorinostat and temsirolimus for 10 cycles (28 day cycle), while in stratum II patients received vorinostat and temsirolimus for 12 cycles. Neuroimaging including diffusion tensor imaging were evaluated where feasible. RESULTS Three patients were enrolled in each of the stratum. One patient in stratum 1 completed therapy, 2 other demonstrated progressive disease (PD) after 4th and 1st cycle of maintenance therapy respectively. In stratum 2 all patients progressed 2 months after the start of therapy. However no dose-limiting toxicity (DLT) was noted. The patient in stratum 1 who completed therapy, remained free of PD 21 months after diagnosis with continued improvements in the volume of enhancing and T2 hyperintense disease. CONCLUSION Although no significant benefit was seen as compared to historical controls during this study, no dose limiting toxicity was noticed with this treatment.


ALTERATIONS in chromosome numbers, due to the duplication of a single chromosome or an entire haploid genom, are wellknown phenomena in Crepis, as in many other plants. A condition less frequently found is that in which fragmentation or translocation, or a combination of both, occur, producing a new chromosome number. Two plants of C. sibirica have been found in which such a change occurs in one of the chromosomes bearing a satellite, the D-chromosome. These plants were both taken from a single culture. A third plant from the same culture showed the normal genom for this species. The root-tips were taken from the plant in the rosette stage and fixed in chromacetic formalin, using the formula given by Hollingshead and Babcock (1930) as solution I. The chromosomes of C. sibirica consist of five pairs, in one of which the members bear small satellites (Fig. 1). The satellited chromosomes are only ones having a small proximal arm.


375 early pregnancy cases accepted mifepristone tablet and/or misoprostol tablet in groups at different methods and doses. In 115 cases,in which 52 cases amenorrhea ≤34d,accepted single 600mg mifepristone (group Ⅰ) and 110 cases,in which 20 cases amenorrhea ≤34d, accepted mifepristone 600mg and misoprostol 600mg (group Ⅱ). The complete abortion ratio in groups Ⅰ and Ⅱ was 88.0% and 94.1% respectively (P0. 05). The another 150 cases accepted different doses of mefepristone and misoprostol 600μg in three groups and there was no significant difference in the complete abortion ratio.

In this paper, we introduce an open-source model "MOVESTAR" to calculate the fuel consumption and pollutant emissions of motor vehicles. This model is developed based on U.S. Environmental Protection Agency's (EPA) Motor Vehicle Emission Simulator (MOVES), which provides an accurate estimate of vehicle emissions under a wide range of user-defined conditions. Originally, MOVES requires users to specify many parameters through its software, including vehicle types, time periods, geographical areas, pollutants, vehicle operating characteristics, and road types. In this paper, MOVESTAR is developed as a simplified version, which only takes the second-by-second vehicle speed data and vehicle type as inputs. To enable easy integration of this model, its source code is provided in various languages, including MATLAB and C++. A case study is introduced in this paper to illustrate the effectiveness of the model in the development of advanced vehicle technology.


THE EXPERIMENTAL ASPHALTIC CONCRETE PAVEMENTS CONSTRUCTED IN DELAWARE TO EVALUATE THE CHANGES IN THE ASPHALT AND THE PROPERTIES OF MIXTURES DURING CONSTRUCTION AND IN SERVICE DESCRIBED. TWO EXPERIMENTAL ASPHALTS FROM SPECIFIC SOURCES, EACH LAID OVER A RIGID (OLD PORTLAND CEMENT CONCRETE) AND A FLEXIBLE (OLD SURFACE TREATMENT) BASE, WERE USED. THE PRESENT REPORT INCLUDES DATA FROM THREE SERIES OF SAMPLES, THOSE TAKEN DURING CONSTRUCTION AND THOSE TAKEN AFTER ONE AND TWO YEARS OF SERVICE. COMPARISON OF RESULTS OBTAINED BY THREE DIFFERENT LABORATORIES-BUREAU OF PUBLIC ROADS, ASPHALT INSTITUTE, AND DELAWARE STATE HIGHWAY DEPARTMENT-ALSO IS PROVIDED. AT PRESENT, NO SPECIFIC CONCLUSIONS CAN BE DRAWN, BUT LABORATORY TESTS INDICATE THAT DIFFERENCES IN BEHAVIOR OF THE SAME ASPHALT AT VARIOUS LOCATIONS IN THE ROAD MAY BE AS GREAT AS OR GREATER THAN DIFFERENCES IN THE ASPHALTS FROM THE TWO CRUDE SOURCES USED IN THIS STUDY. OTHER THAN MINOR REFLECTION CRACKING FROM THE CONCRETE BASE ON THE RIGID SECTIONS, NO DETERIORATION IN THE PAVEMENTS HAS BEEN NOTED AT ANY LOCATION. /AUTHOR/


Abstract The simultaneous determination of cadmium and lead in cigarette smoke was achieved using a unique impaction-graphite furnace atomic absorption spectrometry system (I-GFAAS), and in inert cigarette parts (whole, tobacco, filter, and paper) using conventional graphite furnace atomic absorption spectrometry (GFAAS) following digestion using a previously established microwave digestion method. Results showed that in both the whole cigarette and the smoke there was about a factor of two in lead compared to cadmium concentrations, typically 17.56 compared to 31.94 mg/g for whole cigarette and 13.41 to 25.72 ng/m3 for cigarette smoke.


Have you been hearing a lot about individualized instruction lately? Have you tried some form of individualization in your classroom? Has it "worked"? Considerable attention has been given this idea in current curriculum reform in elementary school mathematics. Words such as "diagnosis," "prescriptions," "contracts," "I PI," "continuous progress," and so on, are heard often, and many schools are using what they call individualized mathematics programs. The essence of many individualized programs is portrayed in the following partial description of the IPI (Individually Prescribed Instruction) program developed at the University of Pittsburgh (1970):


THE INTRAPERITONEAL injection of a large volume of isotonic glucose solution was I used by Schecter and coworkers (1) and Darrow and Yannet (2) in a study ofJ L the distribution of electrolytes in the various body fluid compartments. Thisdilution of the ascitic fluid leads to a rapid transfer of electrolytes contained in theextracellular fluid into the peritoneal cavity, followed by a transfer of water into theintracellular compartment to restore osmotic equilibrium between it and the extra cellular compartment. Since the rate at which this electrolyte is shifted is greaterthan that at which glucose is absorbed from the peritoneal cavity, there is a tempcrary but severe concentration of the extracellular fluid volume. The plasma must actas the intermediary in this transfer, yielding electrolyte and water from itself to theascitic fluid, replacing it in turn from the various parts of the interstitial fluid, so thatthere is always a tendency for a disproportionate decline in plasma volume.


A significant volume expansion exhibited by high‐capacity active materials upon lithiation has hindered their application as Li‐ion battery anode materials. Although tremendous progress has been made in the development of coating methods that improve the stability of high‐capacity active materials, suitable coating sources that are both strong and economical to use are yet to be discovered. Pitch is reported here as a promising coating source for high‐capacity anodes owing to the high mechanical strength and low‐cost process. Using in situ transmission electron microscopy, it is found that pitch can withstand the severe volume expansion that occurs upon Si lithiation owing to its high mechanical strength, originating from the long‐range graphitic ordering. Notably, pitch‐coated silicon nanolayer–embedded graphite (SG) exhibits superior capacity retention (81.9%) compared to that of acetylene‐coated SG (66%) over 200 cycles in a full‐cell by effectively mitigating volume expansion, even under industrial electrode density conditions (1.6 g cc−1). Thus, this work presents new possibilities for the development of high‐capacity anodes for industrial implementation.


To evaluate the effectiveness of chlormadinone acetate (CMA) for preventing premature LH surge in patients with normal ovarian reserve compared to cetrorelix.

 In progestin-primed ovarian stimulation (PPOS) than GnRH antagonist (GnRH-ant), the incidence of premature LH surge was significantly lower, without significant difference in oocyte maturation rate.

 The GnRH-ant protocol is one of the conventional protocols which has some disadvantages including increased premature LH surge rate and cancelation rate. In recent years, the PPOS protocol has attracted attention as a new ovarian stimulation using progestin as an alternative to GnRH analog for suppressing a premature LH surge, however its efficacy is still controversial. In addition, many studies have investigated the reproductive outcomes of PPOS using medroxy-progesterone acetate or dydrogesterone; however, there are few reports of CMA, an oral progestin, which is inexpensive and widely used in Japan.

 This retrospective cohort study was performed in a reproduction center between March 2018 and October 2020 which included 977 Japanese patients with normal ovarian reserve undergoing PPOS with CMA (n = 299), or GnRH antagonist (GnRH-ant) with cetrorelix (n = 608) in their first IVF cycle at the reproduction center. In subgroup analysis, pregnancy outcomes after frozen embryo transfers (FET) between PPOS (n = 284) and GnRH-ant (n = 579) were also compared.

 The inclusion criteria were patients aged < 40 years and AMH ≧ 1.1 ng/mL, who underwent autologous oocyte retrieval in their first IVF cycle with freeze-all strategy. The primary outcome was the incidence of premature LH surge, the secondary outcomes was oocyte maturation rate. To reduce the impact of treatment bias and potential confounding factors, we conducted logistic regression models with inverse-probability-of-treatment weighting (IPTW).

 After IPTW, baseline clinical data were well-balanced between the two groups, including age, AMH, BMI, the duration, type, and cause of infertility, antral follicle count, the history of recurrent spontaneous abortion, and previous IVF attempts. The premature LH surge rate was significantly lower with PPOS (3.1%) compared to GnRH-ant (20.1%) (odds ratio, 0.21; 95% confidence interval, 0.11–0.36). No significant differences were found in total gonadotropin dose (2400IU for PPOS vs 2400IU for GnRH-ant, p = 0.136), the number of oocyte retrieval (n = 15 vs n = 15, p = 0.484), oocyte maturation rate (78.8% vs 77.8%, p = 0.275), fertilization rate (73.0% vs 72.0%, p = 0.412), viable embryo rate per oocyte retrieval (40% vs 40%, p = 0.890), and good quality blastocyst rate (72.0% vs 69.6%, p = 0.092). However, the good quality day-3 embryo rate was significantly lower with PPOS (37.2% vs 49.1%, p < 0.05). There were no differences in the incidence of moderate-to-severe OHSS (0.3% vs 0.7%, p = 0.481). In FET cycles, the pregnancy outcomes, such as implantation rate (43.1 % vs 51.9 %, p = 0.013) and clinical pregnancy rate (46.5% vs 54.7%, p = 0.027) were significantly lower with PPOS, however, no significant differences were found in ongoing pregnancy rate (75.6% vs 80.5%, p = 0.325), and live birth rate (72.4% vs 79.5 %, p = 0.142).

 This was a retrospective cohort study conducted in a single center. The participants in this study were limited to Japanese ethnicity. The results need to be validated across different centers and other ethnicities.

 This is the first report assessing the reproductive outcomes on PPOS using CMA, widely used in Japan. The PPOS with CMA significantly suppressed the premature LH surge rate compared to GnRH-ant protocol, without decrease in oocyte maturation rate.

We predict a spatially varying mode population to appear in a ballistic quantum channel formed in the two-dimensional electron gas of a gated GaAs/AlGaAs heterostructure due to pumping by a THz field. If a resonant coupling between two modes is suddenly switched on at the entrance, Rabi oscillations in the mode population will arise. We propose to use an array of gates in order to simulate a moving quantum point contact for detecting mode population oscillations since they discriminate between different modes. By consecutively activating them we expect to see both photovoltaic effects and photoconductive effects that can easily be distinguished from noise.

IN previous experiments (Kovacs and David, 1963) we demonstrated in agreement with Byrom's (1938) results that in oestrone pretreated rats administration of posterior pituitary extracts (Piton, Organon) induces focal renal cortical necrosis of hypoxic origin. Piton by itself in the doses applied does not evoke any appreciable morphological change. Hence, it seemed justified to assume that oestrone pretreatment increases the sensitivity of the renal vessels to the vaso-constrictive effect of Piton. This opinion has also been supported by the investigations of Lloyd (1959), Lloyd and Pickford (1962) and Deis, Lloyd, and Pickford (1963) who found that in rats and dogs being under the effect of oestrogens, the vasopressor action of vasopressin becomes more intensive. Subsequently using Sapirstein's 86Rb method (1956, 1958) it could be observed that in oestrone pretreated rats one hour after Piton administration the renal blood flow diminished considerably (Kovacs, Csernay and David, 1964). Therefore our data suggest that in oestrone pretreated animals Piton induces a prolonged spasm in the renal vessels which evokes a long lasting renal hypoxia and so tubular necrosis develops. Considering that there is a close correlation between the pituitary and renal function it seemed worth while to examine whether the removal of the pituitary influences the development of tubular necrosis caused by hormones. The present paper reports the results of these experiments.


A fuzzy control scheme for self-steering of a sailboat is presented in this paper sc that the sailboat can automatically sail along the desired course and at the highest speed. First, the dynamic characteristics of the sailboat including the aerodynamic and hydrodynamic forces itre studied. Then the control algorithm is developed as two subsystems for achieving speed control and course control. The object of speed control is to reach the f'astest speed of the sailboat (the scl-callcd velocity made good) for any sailing direction by adjusting the sail angle. A fuzzy relation between the sail angle and the apparent wind direction is obtained to determine the sail angle after thtdetailed consideration of propulsion effectiveness generated from the lift and drag forces acting on the sail under differnt apparent wind directions. While the course control will be achieved by adjusting the rudder angle to correct for the heading error and to compensate for the yawing moment caused by the aerodynamic force on the sail. A fuzzy course controller is formulated with heading error and yaw rate a s inputs, rudder angle change rate as outputs, and a set of linguistic rules among them. Part of the rudder angle ir determined based on fuzzy inference for compensating the yawing moment from the sail. Nonlinear computer simulation shows that the sailboat can indeed maintain at the highest possible speed and follow the course command with desirable response.

Electronic commerce has been future to be the new driver for economic growth and also touches all aspects of economic life and presents a series of critical issues. It includes the collection of numerous elements of technologies, e- commerce infrastructure, some of the business operation and policy etc. All these elements need to work together as smooth as possible to find the maximum benefits to customers. Most importantly, e-commerce requires new skills and forms of industrial organization. The SMEs sector plays an important role in its contribution to the growth of national economy in the terms of monetary values. This paper's focus is not on small medium enterprises; it is depend upon barriers for any businesses adoption to electronic business. This study was therefore initiated to identify the barriers to adoption of e- commerce technologies from the various points of views. The barriers found, as a result from overview on various literature that are presented and related to previous research in this area. Keyword- E-Commerce Barriers, E-Commerce Adoption Barriers, Literature Review on E-Commerce, Small and Medium Enterprises (SMEs).


The aim of the study was to evaluate the responsiveness of the Short Form Health Survey, the EuroQol 5 Dimension questionnaire, and the Charing Cross Venous Ulcer Questionnaire (CXVUQ) to venous ulcer healing. Participants had health‐related quality of life measured at baseline and 12 weeks. Standardized response means were calculated to assess the responsiveness of the instruments to change in an ulcer state (healed vs. unhealed). Three hundred and sixty‐eight participants completed the questionnaires at baseline and 360 at 12 weeks. One hundred and ninety‐three participants (54%) had healed at 12 weeks. The standardized response means ranged from −0.01 to 0.47 for Short Form Health Survey, 0.10–0.31 for EuroQol 5 Dimension questionnaire, and −0.21 to −0.92 for CXVUQ. Differences between healed and unhealed participants at 12 weeks were significantly different for three of the eight domains on Short Form Health Survey and on all domains for the CXVUQ. There were no significant differences between the groups on the EuroQol 5 Dimension questionnaire scales. CXVUQ was more responsive than the generic instruments to change in ulcer status over 12 weeks for measuring health‐related quality of life of patients with venous ulceration.


Urbanization is both a landscape process and a demographic process. Most people are familiar with the changes on the landscape that have occurred on both local and global scales, and virtually all of us have experience with the profound changes in the neighborhoods, towns, and cities where we have lived. Such large-scale urbanization has occurred in all developed and most developing nations. In addition to these widespread landscape changes, demographic changes to the world's human population have reached the point where now more than half of the 7.3 billion people on the planet are urban dwellers.1 This trend toward urbanization is projected to continue, with increasingly fewer people living and working in rural environments. Along with these changes to our demographic profile come different experiences, attitudes, and opinions about how we view our place in nature.2


Two primary areas are investigated in this study; 1) a single subject replication of Shelton and Elbert (1967 a&b), in which generalization from a voiceless sound /s/ to its voiced cognate /z/ is tested; 2) a reversal of the Shelton and Elbert (1967 a&b) procedure with a single subject to determine if training on a voiced phoneme /z/ will generalize to its voiceless cognate /s/. A third area of interest will be to see if any change will occur on the phoneticallydissimilar sound /r/ in either subject.


Various theoretical models of the formation of spatial structures in a reaction system containing compounds with hydroxyl and isocyanate functional groups were considered as dependent on the kinetics and mechanism of the reagent association and the formation of urethane group. It was shown that inhomogeneous concentration distribution in the system arises when the reaction involves heteroassociates of the reagents. A difference of the local reaction rate of the polyurethane formation from volume-average reaction rate, caused by the inhomogeneous associate distribution, may result in the microheterogeneity of polyurethane and structure properties frequently observed in practice.


Electrochemistry has been introduced as a powerful tool in order to prepare new organometallic reagents for functionalizing of mesoporous silica. Preparation of the reagents was based on electrochemical oxidation of dihydroxybenzene derivatives in the presence of 3-(trimethoxysilyl)-1-propanethiol as a nucleophile. The mechanisms of electrochemical reactions were studied by voltammetric studies. Mesoporous silica SBA-15 was also synthesized in this work through sol-gel hydrothermal method using Genapol PF-10 as structure directing compound. The prepared mesoporous silica was characterized by FT-IR analysis and Barrett–Joiner–Halenda (BJH) pore size and Brunauer–Emmett–Teller (BET) surface area measurement methods using N2 adsorption–desorption isotherm. Finally, the organometallic reagent was covalently grafted on the surface of mesoporous silica. Functionalizing of this material with the new reagent was confirmed by Fourier transform infrared (FT-IR) spectroscopy. The functionalized mesoporous silica by new reagent can be utilized in biological applications.


In this paper we consider the relationship between contractualism and primary health care policy. The methodology includes interviews with the main actors (managers and health care professionals) and analysis of the contract documents. Based on the author's PhD dissertation, the paper will examine how politicians use contracts to pass on health policy priorities to primary health care centres. We will also explore the results and contradictions of this process with the aim of finding out the effects of contractualism on health policy.


Ever since the days of Sir Thomas More and Robert Owen, people have been engaged in studying and predicting the future. Today's futurist has refined the art to such a high degree that futures studies have important implications for business strategic planning.


Diode clamped multi-level inverter (DCMLI) gains more and more attention in fields of high power and voltage due to its simple structure, high quality output wave and ability to decrease the rated voltage of switch devices. But there exists the problem of capacitor voltage unbalance, and when the number of level increases, the space vector modulation (SVM) algorithm becomes more difficult to apply. This paper introduced a universal fast SVM algorithm based on 60° coordinate, which can easily get the three nearest vectors around the reference vector and their dwelling time. All redundant space vectors can be obtained quickly without lookup table through the rule for the distribution of space vector. The switching principle and output sequence of vectors are also analyzed. Based on the fast algorithm, capacitor voltage balance under different power factors is studied by using two methods: selecting redundant vectors dynamically and selecting vector sequence dynamically. Furthermore, this paper analyzes the cause of capacitor voltage unbalance under high power factor load in general sense, and puts forward a practical way to solve this problem for five level DCMLI. Simulation results verify the validity of the algorithm proposed in this paper.

In the framework of Network Function Virtualization (NFV), we address in this work the design and sizing of Cloud-RAN architectures. We concretely investigate the execution time of software-based Base Band Units (BBUs) on multi-core systems. Since Cloud-RAN requires a real-time behavior, we use parallel programming techniques in order to minimize the runtime of BBU functions. For an efficient utilization of computing resources, we investigate the relevance of resource pooling where a global scheduling algorithm allocates processing units to runnable BBU-jobs. We specifically examine the gain that can be obtained when applying data parallelism on the channel decoding BBU-function which is the most expensive one in terms of processing time. Performance results show a significant reduction in the runtime of PHY functions which enables the deployment of a fully centralized Cloud-RAN architecture.


ABSTRACT The purpose of these notes is to provide examples of large-scale geometry problems that have the potential to promote constructive struggling in high-school geometry classrooms. These problems are suitable for being explored in a dynamic geometry environment. The notes also contain brief sketches of solutions to the two problems.


Being situated in a semi-enclosed Mediterranean lagoon, the Port of Taranto represents a transport, industrial and commercial hub, where the port infrastructure, a notorious steel plant, oil refinery and naval shipyards coexist with highly-dense urban zone, recreation facilities, mussel farms, and vulnerable environmental sites. A Single Buoy Mooring in the center of the Mar Grande used by tankers and subsea pipeline that takes oil directly from tanker to refinery are assumed to stay at risk of accidental oil spills, despite significant progress in technology and prevention.

The oil spill model MEDSLIK-II (http://medslik-ii.org) coupled to the high resolution Southern Adriatic Northern Ionian coastal Forecasting System (SANIFS http://sanifs.cmcc.it Federico et al., 2017) is used to model hypothetical oil spill scenarios in stochastic mode. 15,000+ hypothetical individual spills are generated from randomly selected start locations: 50% from a buoy and 50% along the subsea pipeline 2018–2020. Individual spill scenario is based on a real crude oil spill caused by a catastrophic pipeline failure happened in Genoa in April 2016 (Vairo et al., 2017). The model outputs are processed statistically to represent quantitively: (1) timing of the oil drift; (2) hazard maps in probability terms at the sea surface and on the coastline; (3) oil mass balance; (4) local-zone contamination assessment.

The simulations reveal that around 48% of the spilled oil will evaporate during the first 8 hours after the accident. Being transported by highly variable currents and waves, the rest is additionally exposed to multiply reflections from sea walls and concrete wharfs that dominate in the study area. As a result, the oil will be dispersed almost isotropically in the Mar Grande, indicating a rather moderate or small level of concentrations over the minimum threshold values (French McCay, 2016).

We have concluded that at a probability of 50%, the first oil beaching event will happen within 14 hours after the accident. The most contaminated areas are predicted on and around the nearest Port berths, on the coastlines of the urban area and on the tips of the breakwaters that frame the Mar Grande openings. The remote areas of the West Port and Mar Piccolo are expected to be the least contaminated ones.

Results are applicable to contingency planning, ecological risk assessment, cost-benefit analysis, and education.

This work is conducted in the framework of the IMPRESSIVE project (#821922) co-funded by the European Commission under the H2020 Programme.

The Nb3Sn technology plays a crucial role in developing high-field superconducting magnets. The new-generation Nb3Sn cable greatly contributes to bring the magnetic field produced by the superconducting dipole magnets to the 16 T level; nevertheless, its mechanical properties are largely variable, making it difficult to predict the mechanical behavior of the magnet structure. For this reason, an extended experimental campaign on specimens made from a stack of ten Nb3Sn cables was launched at CERN. The ten-stack can be considered a representative sample of the magnet coil because it is produced following the same construction process: curing, reaction, and impregnation. The experimental campaign consists of compression tests along the three sample directions at room temperature and multiple loading and unloading cycles were performed as it occurs for real magnet coils. A dedicated test bench was designed to measure the vertical and lateral deformations of the sample. This work presents the stress–strain relationships, focusing on the cable-stack stiffness, which strongly depends on the stress level in each loading direction. Moreover, the transverse–longitudinal strain relationships give further information about the complex behavior of the Nb3Sn cable-stack, because the rearrangement of the conductors occurs during the test. A new analytical methodology is proposed to predict the nonlinear behavior of the Nb3Sn composite cable.


In response to gibberellic acid, aleurone layers isolated from dormant barley (Hordeum distichum L. cv. Triumph) kernels produced significantly less alpha-amylase than aleurones from non-dormant kernels. Light microscopical investigations using the dye acridine orange as well as electron microscopical studies showed that the relatively low alpha-amylase production by aleurones from dormant kernels appears to be due to the majority of the cells remaining quiescent after GA3 incubation. The cells that did show ultrastructural signs of GA3-induced activation occurred in clusters that spanned all three cell layers of the dormant aleurone. These cells showed a characteristic ultrastructure, which was different from that described previously for GA3 incubated non-dormant aleurone layers. Dictyosomes, which are extremely difficult to visualise in non-dormant barley aleurone, were abundant. The presence of alpha-amylase in the Golgi could be demonstrated by immuno-gold labelling in these cells. Remarkably, most endosperm-facing aleurone cells in the activated clusters showed no cell wall degradation. This cytodifferentiation pattern could be mimicked in aleurone cells from non-dormant grains by imbibition of the grains in abscisic acid (ABA) prior to GA3 incubation. These data support the notion of heterogeneity of aleurone cells with respect to GA3 sensitivity, and suggest that ABA is involved in the impaired GA3 response of aleurone cells from dormant barley. © 1997 Academic Press Limited.

Deep learning has proven to be a landmark computing approach to the computer vision domain. Hence, it has been widely applied to solve complex cognitive tasks like the detection of anomalies in surveillance videos. Anomaly detection in this case is the identification of abnormal events in the surveillance videos which can be deemed as security incidents or threats. Deep learning solutions for anomaly detection has outperformed other traditional machine learning solutions. This review attempts to provide holistic benchmarking of the published deep learning solutions for videos anomaly detection since 2016. The paper identifies, the learning technique, datasets used and the overall model accuracy. Reviewed papers were organised into five deep learning methods namely; autoencoders, continual learning, transfer learning, reinforcement learning and ensemble learning. Current and emerging trends are discussed as well.


A novel and rapid method to prepare 123 superconductor powder based on microwave processing is reported. A mixture of the nitrates of Y, Ba, and Cu in 123 stoichiometry when subjected to microwaves of frequency 2.45 GHz for 240 s resulted in an appreciable quantity of tetragonal 123 phase. Annealing for a period of 4 h at 940°C in flowing oxygen formed a superconductor having a Tc of 91 K. Sintered pellets of the powder formed by microwave processing have shown transport Jc of 105 A/cm2.


Dry Eye Syndrome is a common disease in the western world, with effects from uncomfortable itchiness to permanent damage to the ocular surface. Nevertheless, there is still no objective test that provides reliable results. We extend our method for the automated detection of dryness signs to include the breakup time (BUT), analysis of the degree of thinning of the tear film and detection of meniscus induced dryness, the last two have not been previously addressed. Our motivation is to help the clinician to automatically detect and analyze various signs related to dry eyes. The method has been tested on over 100 videos taken from 30 different patients. When compared to an analysis done by a specialized optometrist, our method is demonstrated to provide an accurate estimation for the BUT and the extent of the disease.


We investigated the phonon-limited electron mobility in rectangular silicon nanowire metal-oxide-semiconductor field-effect transistors (Si NW MOSFETs) using the Kubo-Greenwood formula. Although cross-sectional electrostatics has been actively investigated, the cross-sectional distribution of the spatially resolved mobility has not been studied yet. In this paper, we discuss the corner effects based on spatially resolved mobility analysis. Taking into account the subband composition for local electrons, we could study the cross-sectional spatially resolved carrier transport. A strongly confined Si NW MOSFET showed that mobility hardly fluctuated in the cross-sectional distribution with strong volume inversion. On the other hand, a less-confined Si NW MOSFET showed that the corner mobility was lower than the side mobility; therefore, our result could imply that the corner effects were not positive for improvement in mobility.
