Drawings by Carlo Maratti in public Italian collections: an evaluation and clarification.
The third centenerary of the death of Carlo Maratti, the celebrated painter who was born in Camerano (near Ancona) in 1625 and died in Rome on 15 December 1713, is an occasion to present a comprehensive view and retrace the provenance of the Maratti drawings to be found in Italian public collections. In fact, the artist was a skilled draughtsman, and his drawings were consistently sought after by collectors and dealers all over Europe from the beginning of the 18th century. As a result, most of these works ended up in the most celebrated collections: the Royal Library at Windsor Castle in Great Britain, the Accademia de Belles Artes San Fernando in Madrid, as well as the Dusseldorf Kunstmuseum and the Louvre in Paris.
Though fewer, there are a number of interesting nuclei in Italy within the most important collections. The Istituto Nazionale per la Grafica has many drawings attributed to Maratti, including some high–quality originals from the Corsini collection, which were assembled in 1728 by Neri Maria Corsini thanks to the acquisition of Cardinal Gualtieri's library. Of equal interest is a study belonging to the biographer Nicola Pio. Indeed, the Istituto has in its safe–keeping a complete volume of drawings and numerous books of prints.
The Gabinetto Disegni e Stampe degli Uffizi in Florence is no doubt the most important collection of drawings and prints in Italy. Even if there was nothing signed by Maratti within the prestigious collection assembled by Cardinal Leopoldo de' Medici, several studies by Maratti have entered the Uffizi collections as parts of subsequent acquisitions. Within the core of the Michelozzi collection (apart from the Resta Codex with drawings by other artists in Maratti's circle), there are two studies, never published, for an engraving depicting Beato Toribio in Prayer. In the Ignazio Hugford collection there are two more noteworthy folios. All of these drawings were aquired at the end of the 18th century by Pelli Bencivenni, the director at that time of the Gallerie in Florence. The largest increase in the number of 17th–century Roman drawings at the Uffizi may be attributed to the legacy of the sculptor Emilio Santarelli, who died in 1866. However, of the 74 sheets attributed to Maratti, only three are originals by the artist. All three are high–quality, even if art historians are able to identify the subject matter and destination of only one of these.
Finally, the author cites a further four drawings: two studies preserved in the Galleria Portatile, the celebrated Codex Resta in the Biblioteca Ambrosiana in Milan; another study for the Beato Toribio in the Gallerie dell'Accademia in Venice, and, lastly, a splendid folio given to the Civici Musei d'Arte in Reggio Emilia by Giulio Ferrari. The latter was a preparatory drawing for the face of a night clock that Cardinal Antonio Barberini gave to the French king Louis XIV between 1660 and 1665.


Applying New Structure, Layout And The speculation and invention of Left-Handed Meta Material (LH MTM) has sparked the interest of many researchers globally. This material is said to have simultaneous negative parameters or double negative parameters (DNG Parameters) of the permittivity and permeability that led to the reversal of multiple theories and laws. Besides, it has the ability to improve the gain of antenna due to its focusing effect from its negative refractive index (NRI) characteristics. Nowadays, conventional microstrip antennas have low gain and directivity compared to other antennas available in the market nowadays. However, this type of antenna is still being used due to its ease of fabrication, light weight characteristics, just to name a few. Therefore, as a mean to make this type of antenna more worthwhile, the integration of LH MTM to this type of antennas was studied through simulations and experiments to prove the hypothesis of the focusing effect. As of the structure design, the combination of the Square Rectangular Split Ring and the Thin Wire Structure was used for fabrication purposes on an FR-4 Board using the Wet Etching Technique. From the simulation done, the gain of the antenna had increased 1.2 dB. This has proven that the focusing effect of the LH MTM really enhance the gain of the antenna. On the other hand, the Return Loss (S11) was improved by 9.62 dB and 12.29 dB in the simulation. Therefore, we could also conclude that LH MTM also contributes to the betterment of the matching of the antenna. Lastly, more alternative designs of LH MTM should be explored in the future and a parameter study should be done to further understand this peculiar LH MTM.


This work deals with compressibility evaluation of mechanically activated Nb and Al powder mixtures by high-energy ball milling. Milling time and quantity of stearic acid, added as a process control agent (PCA), were varied. Starting powders and milled mixtures were characterized by SEM and laser diffraction analysis. A universal testing machine was used for the compressibility tests carried out in a steel cylindrical die. Sample compressibility data from the various conditions of milling were compared from each other. Compressibility was seen to decrease by increasing milling time and quantity of PCA. A new compaction equation could be further provided, showing better fitting to the data of this work when compared to the equation from previous reported models.


The propagation of waves in periodic media is restricted to allowed bands of energy or frequencies separated by forbidden gaps. We propose a discrete variable representation, based on Bloch functions, that is suitable for the calculation of band structures in one-dimensional systems. The solutions are obtained by a single diagonalization without any integration. The method only needs the values of the potential at grid points. Applications to the standard Kronig-Penney and Mathieu potentials, and to the nonanalytical case of a soft Coulomb potential, show that very good accuracy is achieved with moderate grid sizes.


"If you could choose, how would you like the Intensive Care Units (ICUs) to be?" The Humanization of Intensive Care movement (Proyecto HU-CI) arose after we asked this simple question in our blog, receiving suggestions from more 10,000 people (1). Created in Spain on February 2014, the Humanization of Intensive Care movement is an international research project that seeks, using evidence-based medicine, to answer that same question, thus creating a paradigm shift in the way we deliver our care toward a more friendly and human-centered model (2). Although many may be surprised and feel a contradiction toward this humanistic model, is an essential skill in health professionals that should have never been lost. When professionals are face with the reality of being patients or a family member of critically ill patient, it is then, when they appreciate how it works. "Yet many professionals cite lack of humanistic care as a cause for burnout, an epidemic among health professions today" (3). Displaying kindness and concern for all the individuals that are part of the healthcare environment, not only patients and its families, is a necessity and the path toward building an excellent healthcare system. We will not be able to cure all people, but surely, we can improve the care we provide by focusing on the dignity of people. The professional and technical development of the ICUs is remarkable. Proof of this is the high survival statistics that support its excellent results (4). Nevertheless, humanistic aspects of care have not developed as effectively as technological advancements, thereby affecting these three relevant groups (patients, families, healthcare personnel). In many places, the organizational and architectural characteristics of the ICUs create hostile environments for all: that is why humanization must also require structural changes (5). Humanizing means, "everything that has to be done to promote and protect health, cure diseases and guarantee an environment that favors a healthy and harmonious life on a physical, emotional, social and spiritual level in people." "Talking about humanization demands the intrinsic dignity of every human being and the rights that derive from it, and this makes it a necessity of vital importance and transcendence"(6). Humanizing also involves individualizing care by paying attention to what patients and family members need, even if they do not agree with the manner in which we deliver care and turning this into a clinical process, where attitude is fundamental. Humanizing is also understanding and accepting that professionals are fallible and vulnerable and that we need to be contemplate since we are the cornerstone to humanize healthcare. Care requires professional competence and training, but also individuality, emotion, solidarity, sensitivity, and ethics. It requires excellent social and communication skills, empathy, active listening, respect, and compassion to others. However, historically, healthcare professionals have curricular flaws in their training of "human tools," the so-called "soft skills." Through a multicenter and international collaborative research, Proyecto HU-CI aims to evaluate different areas and carry out the implementation of the corresponding improvement actions. These areas of improvement and research (Fig. 1) were identified through active listening and shared reflection on the opinions thousands of healthcare professionals (1). This initiative generated an ICU Humanization plan (7) where each item is explained below, was recognized as a paradigm shift in the healthcare model (8) and has laid the foundations for the ICU Manual of Good Practices in Humanization (9), including 160 actions to transform the healthcare management model (Table 1).

Keith Jordan: firstname.lastname@example.com We encounter a paradox here—that the Surrealists were, on the one hand, progressive and radical, on the other fixed within the world-view of their time. Though bounded by prevailing cultural concepts—evolutionism, psychoanalysis, primitivism—they continually problematized them...Yet while disavowing the discourses of evolutionism and aesthetic primitivism they constructed in their place equally problematic discourses of the fantastic, the magical and the mythical. Though their radicalism enabled them to stand outside some of the dominant bourgeois ideologies of European modernist society, they never broke totally free of the boundaries of their own (largely French) race, language and culture.1


1911 L cancer has surpassed breast cancer as the leading cause of death for females in developed countries, according to a report issued by the American Cancer Society (ACS) that was performed in collaboration with the International Agency for Research on Cancer. The disease has long been the leading cause of death in women in the United States, but this statistic is new for developed countries worldwide. "Since lung cancer takes so long to develop in the body, this data really reflects smoking trends that started 3 decades ago," says Lindsey Torre, MSPH, an epidemiologist with the ACS and lead author of the report. "In the US, for example, smoking rates have been declining for a while, so the lung cancer mortality rate is beginning to plateau." In areas in which the tobacco epidemic has occurred more recently (such as China, Indonesia, and parts of Africa), lung cancer rates are likely to increase for at least the next several decades unless interventions can make progress in smoking cessation and prevention, according to the report. "Because the epidemic is relatively young in developing countries, there is still time to intervene," Torre says. "It's not definitely a given that it's going to happen." The finding was reported in the recent "Global Cancer Statistics, 2012" article, which appeared in CA: A Cancer Journal for Clinicians, and the 3rd edition of the consumer publication Global Cancer Facts & Figures, published by the ACS, which both were released on World Cancer Day on February 4, 2015.1 The analysis is based on 2012 worldwide estimates of cancer and mortality produced by the International Agency for Research on Cancer for their GLOBOCAN series. The previous analysis focused on data from 2008. Developed countries include all regions of Europe plus North America, Australia and New Zealand, and Japan, whereas developing countries include all regions of Africa, Asia (except Japan), Latin America, the Caribbean, Melanesia, Micronesia, and Polynesia. The results are not surprising, but "very worrisome and point to a need for action on a number of fronts," says Suresh S. Ramalingam, MD, a lung cancer specialist and director of the division of medical oncology at Emory University in Atlanta, Georgia. Torre says that one reason why developing countries have higher numbers of deaths is their proportionally larger share (82%) of the global population. The good news, according to her and other experts, is that lung cancer is one of the most preventable cancers that can, in many cases, be avoided by eliminating smoking initiation and increasing smoking cessation in current smokers. To do so requires a comprehensive tobacco control program that includes raising the price of tobacco products through excise taxes, banning smoking in public places and tobacco sales to minors, limiting tobacco advertising and promotion, using counteradvertising, and providing treatment and counseling for smokers. The hope is that if more countries adopt such efforts, particularly countries in the early stages of the tobacco epidemic such as India and China, lung cancer incidence and mortality rates could be significantly impacted.


Obstetrics and Gynaecology in General Practice: the primary care handbook and aide memoire — this is a really useful publication which overviews obstetrics, gynaecology and family planning as it applies to practising primary health care professionals. The approach is straightforward, aiming to give the reader a rapid reference and aide memoire during consultation with women. It offers a bird's-eye view of conditions important to primary care and consequently is not designed as a comprehensive text. It is clearly written in a style of writing that captures the reader.


FTIR spectra of Rhodamine575 dye in powder form and in different solvents are reported. Positions of some of the observed FTIR bands show noticeable change in solvents. The bands, which shift, have contributions from the vibrational motion of nitrogen atoms of the ethylamine groups, oxygen atom of the carboxylic group attached to the phenyl ring and oxygen atom of the Xanthene ring.


Several quantitiative methods of urine microscopic examination for bacteriuria and pyuria on a blood cell counting‐chamber have been found reliable for the diagnosis of urinary tract infection (UTI). However, no one technique has become popular or widely used because of laborious procedures associated with the method. We investigated the usefulness of microscopic examination of uncentrifuged urine on disposable counting‐chambers.


Fertility trends in the United Kingdom and in 13 other developed countries from 1966 to 1986 are analyzed using data from official national and international sources. Specifically "trends in overall and age-specific fertility rates and in the proportion of births occurring outside marriage in the United Kingdom during the twenty-year period 1966 to 1986 are compared with the equivalent trends in the constituent countries of the United Kingdom in nine of the larger countries of Western Europe and in the U.S.A. Japan Canada and Australia." (EXCERPT)


Src-homology region 2 (SH2) domains, by binding to tyro- sine-phosphorylated sequences, mediate specific protein-protein interactions important in diverse signal transduction pathways. Previous studies have shown that activated forms of the A b 1 tyrosine kinase, including P210""' of human chronic myelogenous leukemia, require the SH2 domain for the transformation of fibroblasts. To determine whether SH2 is also required for Bcr/Abl to transform hematopoietic cells, we have studied two SH2 domain mutations in P210-m: a point mutation in the conserved FLVRES motif (P210/R1053K), which interferes with phosphotyro-sine-binding by SH2, and a complete deletion of SH2 (P210/ ASH2). Despite a negative effect on intrinsic Ab1 kinase ac- tivity, both P210 SH2 mutants were still able to transform and soft agar colony growth in fibroblasts: transformation of hematopoietic factor-depen-dent cell lines to growth factor independence:* transformation of bone marrow cells in vitro: and induction of leukemia in mice.Ia1'


This paper reports that slurry pumps with replaceable cast liners have been merged with API-610 pump design criteria. At one refinery these types of pumps were getting more than six years of life on the wear liners, while the pervious pumps with hard coatings typically lasted six months. In August 1990, the National Petroleum Refiners Association (NPRA) held its Cat Cracker Seminar as a forum to discuss maintenance and mechanical problems. One of the questions on the agenda under Rotating Equipment was: What coatings and materials are being used for slurry pump internals, i.e., case, wear rings, impeller, liners, etc. A lengthy discussion ensured, highlighting the fact that many users were having widely varying degrees of success (acceptable pump life) with their cat cracker slurry pumps; mostly less than desirable.


We examine 25 years of Statistics Canada data on university undergraduate enrolment and gradation rates from 1979 to 2004 by employing field-specific indices of association that measure the under- or overrepresentation of women in a particular field relative to the gender composition in all fields. Our findings reveal patterns of convergence and divergence but, most consistently, of steadiness with respect to gender integration. An overall index of association for undergraduate enrolment indicates that over 25 years gender segregation has decreased by only 5 percent. The comparable figure for degree completion is 13 percent. Spectacular increases in enrolment and completion by women have not been translated into gender integration within most fields of study, suggesting that different structures of opportunities within higher education continue to perpetuate gender inequities in the labour market.

A Three-layer gas pipe is analyzed by using developed program MULTICOAT and the results are
compared with experiments. The MULTICOAT is developed by using Excel and verified by comparing the
results with the commercial program ANSYS. The three-layer gas pipe is manufactured at high temperature
and then falls down room temperature. Therefore, three-layer gas pipe has thermally induced residual stresses.
In this case, there is a quite possibility of destroying the pipe and a fatal accident. In order to analyzing the
residual stress, the pipe is divided into many rings and each ring has constant material properties. And an
analysis of behavior of pipe is based on an assumption of a generalized plane strain(GPS) that all the rings are
free to extend or contract in the axial direction. The calculated results become the base to make the
international standard and extend of pipe's durability and stability.


Online physician reviews (OPRs) critically influence the patients' consultation decisions on physician rating websites. The increasing number of OPRs contributes to the challenge of information overload. The worth of development needs to be explored further. Based on the OPRs collected from RateMDs and Healthgrades, and Plutchik's wheel on human emotions framework, the purpose of this study was to examine the impact of emotional intensity (positive and negative) incorporated in OPRs on review helpfulness (RH). The proposed model was empirically tested using data from two physician rating websites and applying a mixed-methods approach (text mining and econometrics). The results suggested that anger, disgust, and fear (negative emotions), while joy, anticipation, and trust (positive emotions) significantly contributed to the perceived RH. Moreover, the patient's disease severity moderated the association between negative emotions (anger and disgust), or positive emotions (joy and trust) and the perceived RH. Anger incorporated in an OPR has a more negative impact on perceived RH for severe diseases than the mild diseases. The findings contributed to the significance of emotions in OPRs from an innovative perspective and provided practical insights for health rating platform owners to help patients in expressing their emotions more precisely.


This works presents the research on painting technology and techniques of selected panel paintings by Anton Möller (1563/5-1611) and the paintings attributed to his workshop and circle of his artistic influences such as Isaac van den Blocke (before 1589-after 1924) and Hermann Han (1580-1627/8). Gdańsk's painting of the turn of the 16th and 17th centuries was a combination of technology and techniques derived from local traditions influenced by northern trends: German and Dutch, as well as their assimilated Italian art. The results of performed analysis revealed that the works Painting works by Anton Möller... BOŻENA SZMELTER-FAUSEK, JUSTYNA OLSZEWSKA-ŚWIETLIK * This article was based on interdisciplinary research carried out as part of research projects of Ministry of Science and Higher Education No. N 10503731/3704 (cat. no. of paintings 1–4, 17), National Science Center NN105430940 (cat. no. 1–4, 17), MNiSzW No. NN 204370340 (cat. no. 5–10, 12, 14–16, 18–23). 134 BOŻENA SZMELTER-FAUSEK, JUSTYNA OLSZEWSKA-ŚWIETLIK by Anton Möller had a great influence on the development of the painting workshop in Pomerania. The white ground and grey imprimatura and colorful ground characteristic for the Gdańsk artist were identified, among others, in the Gronau epitaph and works by Hermann Han and Isaac van den Blocke. Artists working in this area could be influenced by the painting school of Anton Möller, and they could draw technical achievements directly from the Netherlands. The dominant pigments in Möller's painting palette are lead white, lead-tin yellow, red and yellow iron pigments of natural origin, cinnabar, minium, organic red pigment, smalt, natural azurite, iron umber, charcoal. Anton Möller and Isaac van den Blocke as the only Gdańsk artists used natural ultramarine in their paintings. Anton Möller's work distinguishes the use of bright colors similar to Italian and Flemish paintings. The artist in some way experimented with color. He used various colors of mortar, imprimatura, and underpainting to achieve the desired effect, including a white imprimatura for illuminating the surface of the painting or a pink gound layer for painting the sky. The composition of the painting was underpainted with brown paint that gave a warm tint. When painting garments, especially red, he used strong contrasts of shimmer, where the vivid red was assembled with a plane painted red with the addition of a large amount of lead white. These treatments were supposed to give the impression of luminosity, which brings even closer the way of color compositions with Italian painting. Anton Möller applied the principles of technology and painting techniques typical of the turn of the 16th and 17th centuries in European art and belongs to a group of outstanding artists active in Gdańsk. Abstrakt Anton Möller na tle gdańskiego warsztatu malarskiego ostatniej ćwierci XVI i pierwszej połowy XVII w. Praca przedstawia badania techniki i technologii wybranych obrazów sztalugowych Antona Möllera (1563/5–1611) i obrazów przypisanych do jego warsztatu i kręgu jego oddziaływania artystycznego, jak dzieła Isaaca van den Blocke (przed 1589–po 1924) i Hermanna Hana (1580–1627/8). Gdańskie malarstwo przełomu XVI i XVII w. było połączeniem technologii i techniki wywodzącej się z tradycji lokalnej pozostającej pod dużym wpływem trendów północnych: niemieckich i niderlandzkich, oraz asymilowanych przez nich osiągnięć włoskiej sztuki malarskiej. Przeprowadzone badania gdańskiego malarstwa ostatniej ćwierci XVI i pierwszej połowy XVII w. wykazały, że twórczość Antona Möllera miała duży wpływ na kształtowanie się warsztatu malarskiego na terenie Pomorza. Białą zaprawę i szarą imprimaturę oraz barwne zaprawy charakterystyczne dla gdańskiego artysty zidentyfikowano między innymi w epitafium Gronau i obrazach Hermanna Hana oraz Isaaca van den Blocke. Artyści działający na tym terenie mogli być zarówno pod wpływem gdańskiej szkoły malarstwa, Antona Möllera, jak i mogli czerpać techniczne osiągnięcia bezpośrednio z Niderlandów. Dominujące pigmenty w palecie malarskiej Möllera to biel ołowiowa, żółcień cynowo-ołowiowa, żółte i czerwone pigmenty żelazowe pochodzenia naturalnego, 135 PAINTING WORKS BY ANTON MÖLLER... cynober, minia, czerwony pigment organiczny karmin, smalta, azuryt naturalny, umbra żelazowa, czerń roślinna. Anton Möller i Isaac van den Blocke jako jedyni artyści gdańscy zastosowali w swoich obrazach ultramarynę naturalną. Twórczość Antona Möllera wyróżnia zastosowanie jasnej kolorystyki zbliżonej do malarstwa włoskiego i flamandzkiego. Artysta w pewien sposób eksperymentował z kolorem. Wykorzystywał różne kolory zaprawy, imprimatury i podmalowania do osiągnięcia zamierzonych efektów, między innymi białą imprimaturę do rozświetlenia powierzchni obrazu, czy różową zaprawę do namalowania nieba. Kompozycję obrazu podmalowywał brązową farbą, o ciepłym odcieniu, która nadawała ciepły koloryt. Malując szaty, szczególnie czerwone, stosował silne kontrasty światłocieniowe, gdzie żywą czerwień zestawiał z płaszczyzną namalowaną przy użyciu czerwieni z dodatkiem dużej ilości bieli ołowiowej. Zabiegi te miały wywołać wrażenie świetlistości, co jeszcze bardziej zbliża sposób kompozycji barwnych z malarstwem włoskim. Antona Möller stosował zasady technologii i techniki malarskiej typowej dla przełomu XVI i XVII w. w sztuce europejskiej i należy do grona wybitnych artystów działających w Gdańsku. Anton Möller was born in 1563/1565 in Königsberg and he died in 1611 in Gdańsk. He is one of the leading artists of Pomerania region of the end of the 16th and the first half of the 17th century. He mainly painted works presenting biblical and allegorical scenes on the background of the buildings of Gdańsk. His paintings were primarily intended for exhibiting in public buildings as well as in churches. As a painter, he ran a painting workshop that was significant in Pomerania and which contributed to the formation of one of the most important artistic centres in Gdańsk. Other artists who also had a significant influence on the artistic formation of painting workshops in Pomerania were: a Dutch Hermann Han (1580–1626/1627), born in Gdańsk, who, apart from Gdańsk, also maintained a workshop in Chojnice, as well as two artists from the Netherlands: Hans Vredemann de Vries (1527–1604) – an architect, interior decorator and a painter and Isaac van den Blocke (before 1589–after 1624), a painter and a member of the Flemish family from Mechelen. At the turn of the 16th and 17th centuries the Gdańsk painting was a combination of techniques derived from the local tradition, which were strongly influenced by northern trends in paintings: German and Dutch, and the assimilated achievements of Italian painting1. 1 Willi Drost, Danziger Malerei vom Mittelalter zum Ende des Barock.

The selection of works was determined by the choice of representative works but also by their availability and the consent of individual institutions. The most significant works were chosen, allowing for a thorough and precise characterization of painting technology and techniques. The list of works and examination results are included in tables 1. and 2. The order of works in the table was done according to the date of completion.

After rejecting the null hypothesis in the analysis of variance, the next step is to make the pairwise comparisons to find out differences in means. The purpose of this paper is threefold. The foremost aim is to suggest expression for calculating decision limit that enables us to collect the test and pairwise comparisons in one step. This expression is proposed as the ratio of between square for each treatment and within sum of squares for all treatments. The second aim is to obtain the sampling distribution of the proposed ratio under the null hypothesis. This sampling distribution is derived exactly as the beta distribution of the second type. The third aim is to use beta distribution of second type and adjusted p-values to create adjusted points and decision limit. Therefore, reject the null hypothesis of equal means if any adjusted point falls outside the decision limit. Simulation study is conducted to compute type I error. The results show that the proposed method controls the type I error near the nominal values using Benjamini-Hochberg'adjusted p-values. Two applications are given to show the benefits of the proposed method.


Background: Toxoplasma gondii is a single-celled parasite commonly found in mammals. Diagnosis of toxoplasmosis largely depends on measurements of the antibody and/or antigen and Toxoplasma-derived DNAs due to the presence of tissue dwelling quiescent cysts and latent infection of the parasite. As a major surface antigen of T.gondii tachyzoites, SAG1 is a key marker for laboratory diagnosis. However, at present, there are no methods available for SAG1 detection using aptamer-based technology.Methods: Recombinant truncated SAG1(r-tSAG1)of Toxoplasma WH3 strain (type Chinese 1) was prokaryotically expressed and subjected to the synthetic oligonucleotide library for selection of nucleic acid aptamer which targets the r-tSAG1, with systematic evolution of ligands by exponential enrichment (SELEX) strategy. The screened specific aptamer-2 was used in direct enzyme-linked aptamer assay (DELAA) to detect native SAG1 obtained from tachyzoite lysates, mouse sera of acute infection, and human sera that had been verified to be positive for ToxoDNAs by PCR amplification. Results: The soluble r-tSAG1 protein was obtained from E.coli lysates by using 0.01M Tris-Cl in PBS, and was purified and identified by immunoblotting, and then labelled with biotin. The screened aptamers were amplified by PCR, followed by DNA sequencing. The results showed that the aptamer-2, with the highest affinity to nSAG1 among the four aptamer candidates, has a higher specificity and sensitivity when used in detection of nSAG1 in the sera of both animals and humans when compared with the commercial Toxoplasma circulating antigen testing kit.Conclusions: A new direct enzyme-linked aptamer assay (DELAA), with aptamer-2 as the recognition probe, was developed for detection of native SAG1 protein secreted by T.gondii. With increased sensitivity and specificity, stability during storage, easy and cheaper production, the aptamer-based technique is considered as a efficient method for the diagnosis of active and reactivated toxoplasmosis.

In this paper, two numerical methods are proposed for solving distributed-order fractional Bagley-Torvik equation. This equation is used in modeling the motion of a rigid plate immersed in a Newtonian fluid with respect to the nonnegative density function. Using the composite Boole 02BC &#xs rule the distributed-order Bagley-Torvik equation is approximated by a multi-term time-fractional equation, which is then solved by the Grunwald-Letnikov method ( GLM ) and the fractional differential transform method ( FDTM ). Finally, we compared our results with the exact results of some cases and show the excellent agreement between the approximate result and the exact solution.


This chapter provides an overview of select trends, ideas, themes, and figures associated with humanism in the Americas, which comprises a diversified set of peoples, cultural traditions, religious orientations, and socio-economic groups. In acknowledging this rich tapestry of human life, the chapter emphasizes the impressive variety of developments in philosophy, the natural sciences, literature, religion, art, social science, and political thought that have contributed to the development of humanism in the Americas. The chapter also features modern usages of humanism that originated in the English-speaking world in the nineteenth century. In this context, humanism is best viewed as a contested site in which its meanings, usages, and rhetorical power reflect a wide range of ideological allegiances that include positive and negative connotations. The complex, layered processes of colonization that are a part of the history of the Americas will also inflect the varied usages and connotations of humanism.


Expensive special equipments are often employed to evaluate the performance of low voltage battery, because of the loss voltage of test terminal and line. In the present paper, an economic method was proposed to evaluate fuel cell performance using the booster power supply and electronic load with remote sense. The testing method was deduced theoretically and applied to study the performance of the direct methanol fuel cell . According to the results, it was found that the method was economic applicable and feasible.


textabstractIn radiotherapy of pelvic cancers, the X-ray dose to be delivered to the tumour is
limited by the tolerance of healthy surrounding tissue. In the past, with orthovoltage
equipment, skin tolerance was the main limiting factor. With the introduction of
megavoltage equipment, it became possible to deliver a higher radiation dose to
deep-seated lesions, but inevitably also to neighbouring normal tissues. As a result,
local cure rates were increased, but so was the number of complications.
In recent years we encountered a number of serious complications of irradiation of
pelvic organs. It was in particular in cases of ovarian cancer where a higher dose of
irradiation was applied that these distressing complications were frequent. This experience
led to a more conservative irradiation protocol in these cases, resulting in a
marked fall in the number of complications. In cervical and endometrial cancer the
damage never was as extensive as in the ovarian cancer group. At present many
patients who have to ondergo pelvic irradiation, however, will have transient or
longer lasting symptoms caused by the irradiation.
Modern radiotherapy necessitates the acceptance of a calculated risk of complications
in order to achieve a better cure rate. To calculate these risks, one has to know
the radiation dose-effect relationship of normal tissues. In quantitative terms these
risks are insufficiently known. The normal tissues most at risk when treating pelvic
tumours are the bladder, the ureters, the rectum, the sigmoid colon and the small intestine.
In this study we limit ourselves to the bowel.
The literature regarding postirradiation bowel complications is very confusing. In
the first place no two authors used the same criteria for what they consider to be
bowel complications. Some authors only include severe complications like stenoses
of the bowel and fistulas, in particular those that require surgical intervention (5, 8).
Other authors include patients with diarrhea and/ or malabsorption, whereas a third
group will include ill defined situations that necessitate long-term hospitalization.
It is clear that in this way severe and mild complications are often mixed. The result
is that in different series the incidence of severe gastro-intestinal complications
varies as much as from I to 15"7o (l-12).lt is to be noted that in these studies damage to the small intestine form only a minority. Another drawback of the reported studies
is that all were retrospective. In addition when patients appear to have a recurrence
of their tumour in parallel with radiation damage, they are often excluded
from further evaluation.
In view of the rarity of the severe postirradiation bowel syndromes, a prospective
study of these complications would require a very large number of patients. This
type of study has never been undertaken.


Objective: To investigate the effect of Compound Chinese Traditional Medicine Feiyanning (FYN) on the side population (SP) of lung cancer cells, and to explore its possible mechanism.Methods: The proliferation of lung cancer A549 cells treated with 0, 50, 100, 200, 300, 400, 500 μg/mL FYN or 0, 1, 2, 3, 4, 5, 6, 7 μg/mL cisplatin for 24, 48 and 72 h was detected by CCK-8 assay. The apoptosis of lung cancer A549 cells treated with 200 μg/mL FYN, 3 μg/mL cisplatin, and in combination was detected by FCM. The content of SP in A549 cells treated with 100, 200, 300, 400, 500 μg/mL FYN and 3 μg/mL cisplatin was also detected by FCM. The expression level of ATP-binding cassette transporter sub-family G member 2 (ABCG2) in A549 SP and non-SP cells was detected by Western blotting. Furthermore, the effects of 200 μg/mL FYN and 3 μg/mL cisplatin on the expression of ABCG2 in A549 SP cells were also detected by Western blotting. Results: Both FYN (50-500 μg/mL) and cisplatin (1-7 μg/mL) inhibited the proliferation of A549 cells in a dose- and time-dependent manner (all P < 0.05). FYN (200 μg/mL) induced the apoptosis of A549 cells (P < 0.01), but the apoptosis rates in 200 μg/mL FYN group was lower than that in 3 μg/mL cisplatin group (P < 0.01), while the apoptosis rate in 200 μg/mL FYN + 3 μg/mL cisplatin group was higher than that in 3 μg/mL cisplatin group (P < 0.05). FYN (100-500 μg/mL) down-regulated the percentage of SP in A549 cells in a dose-dependent manner (all P < 0.01). The expression level of ABCG2 in A549 SP cells was higher than that in non-SP cells (P < 0.01), and 200 μg/mL FYN down-regulated the expression of ABCG2 in A549 SP cells (P < 0.01). Conclusion: FYN can inhibit the proliferation of lung cancer cells, and induce apoptosis. Moreover, FYN can down-regulate the percentage of SP in lung cancer cells, and the potential mechanism may be related to inhibiting the expression of ABCG2. DOI:10.3781/j.issn.1000-7431.2018.11.195

AbstractBACKGROUNDReallocation of economic resources between generations and genders has important con- sequences for economic growth and inequality. Unpaid work is a relevant component of intergenerational transfers, but is invisible to traditional accounts. Time use data can complement accounts of monetary transfers.OBJECTIVEThe main goal of this article is to provide estimates of life cycle profiles of consumption and production of unpaid activities. These profiles can be used to evaluate transfers of time by age and sex.METHODSWe use data from the Multinational Time Use Study (MTUS) to estimate profiles of time allocated to unpaid productive activities, by age, sex and household structure, for selected European countries. The unpaid working time is then distributed, with a statistical model, to those age groups that benefit from it, in order to estimate age-specific consumption profiles of time.RESULTSWe observe large transfers of time from females to males, and from adults to children. Life course trajectories are qualitatively similar across countries, but with significant variations in levels. Differences in profiles by household structure may be associated with incentives or disincentives for particular fertility choices in different social and institutional settings.CONCLUSIONSThis article quantifies household production and non-market transfers. It offers insight into the underestimation of the economic contribution of women.COMMENTSThis article provides some descriptive findings that could be incorporated with other re- search pursued by scholars in the National Transfer Accounts (NTA) project to monetize the value of time and include it in standard transfer accounts.(ProQuest: ... denotes formula omitted.)1. IntroductionA large quantity of goods and services are produced by household members for their own consumption, without involving market transactions. Despite the economic and so- cial importance of unpaid work, these productive activities are largely invisible to stan- dard national economic accounts. Consequently, traditional measures of intergenerational transfers typically ignore household production, and thus underestimate the overall value of goods and services produced over the life cycle, in particular, the economic contribu- tion of women.Recently, there have been some efforts to evaluate the extent of household production, and to integrate it into national accounts (e.g., Abraham and Mackie 2005; Anxo et al. 2007; Donehower and Mejia-Guevara 2012; Sambt and Malacic 2012). The increasing availability of harmonized time use surveys has made possible comparative analyses of non-market activities. The estimation of time transfers between generations and genders is intended to create a map of new and partially unexplored territories. The results of this line of research would complement traditional studies of intergenerational market-based transfers between generations and across countries.In this article, we estimate household production and consumption of unpaid work, by age and gender, in a comparative perspective. The profiles that we obtain and the patterns that we document are relevant to address questions such as: to what extent do women contribute more than men to household production? What is the age direction of intergenerational time transfers? How much time do people spend on providing care for their children or elderly parents? How much does the time investment in children vary across countries?2. Data and methodsWe use data from the Multinational Time Use Study (MTUS) to estimate age- and sex- specific profiles of time consumption and production. MTUS includes a collection of time use surveys that have been harmonized to allow for comparative analyses. Large samples of micro data, with information on the allocation of time to various activities of daily life, are available for several European countries. …

Regioselective partial hydrogenation of tricyclopentadiene (TCPD) was achieved with a high turnover number of 10 000 by catalysis with a N-heterocyclic carbene−palladium complex. Copolymerization of ethylene and the partially hydrogenated product, dihydrotricyclopentadiene (HTCPD), was realized using a catalytic system of [8-(η5-C5Me4)-2-Me(C9H8N)-κN]TiMe2 (C9H10NH = 1,2,3,4-tetrahydroquinoline) activated with (Ph3C)+[B(C6F5)4]−. The copolymer was unambiguously characterized through the analysis of one- and two-dimensional NMR spectra. The monomer reactivity ratios, rethylene and rHTCPD, determined through the Fineman−Ross plot, were 2.8 and 0.025, respectively, indicating negligible successive insertion of two HTCPD. A nearly alternating copolymer with a HTCPD content of 45 mol % was obtained with a satisfactory activity (4.7 × 106 g/(mol Ti h)), of which Tg was 177 °C, significantly higher than that of norbornene/ethylene copolymer at the same cycloolefin content. Tensile stress−strain curves indicated ...


Percival Everett has published almost thirty books of fiction in forty years, and The Trees is his 22nd novel. It revisits ideas from Everett's earlier works while asking questions that, in some ways, tie his oeuvre together—these questions can be linked to temporality and history, problematic literary ideas such as post-postmodernism, and both racialised trauma and the flawed cultural concept of the postracial. In this article, I argue that The Trees specifically problematises claims of the postmodern end of history by suggesting that African American literary narrative can productively reckon with a history of mistreatment by literally digging up the past and actively (impossibly) changing it.


This work explores the use of an optimal transport misfit function combined with the coupled acoustic-elastic wave equation for transcranial ultrasound computed tomography. This approach utilizes full-waveform inversion together with a starting model derived from reverse time migration. Source encoding is additionally used to reduce the overall computational cost of the full-waveform inversion reconstruction process. The cycle skipping effects which are accentuated due to the inexact knowledge of the skull geometry can be effectively mitigated using this optimal transport approach. This strategy is validated using an in silico inversion of a numerical brain phantom.


Background. In heart transplantation, myocardial apoptosis during hypothermic storage contributes to graft dysfunction. On the other hand, hepatocyte growth factor (HGF) has been reported to be an antiapoptotic factor in the heart. Therefore, we assessed whether the administration of recombinant human HGF (rh-HGF) prevents apoptosis in the prolonged preserved myocardium, resulting in an improvement in the cardiac function of the graft. Methods. Isolated rat hearts were subjected to 4 hr (group A), 6 hr (group B), and 8 hr (group C: without rh-HGF vs. group D: with 100 &mgr;g of rh-HGF) of hypothermic storage followed by 60 min of normothermic reperfusion (n=5 in each group). Results. Compared with non-HGF-treated hearts (group C), HGF-treated hearts (group D) showed a significantly higher recovery rate of left ventricular developed pressure (38±5% vs. 58±6%, P<0.01) and maximum dp/dt (53±7% vs. 74±4%, P<0.01) and a lower rate of TUNEL-positive cardiomyocytes (7.8±6.0% vs. 25.3±8.9%, P<0.05) after 60 min of reperfusion. Western blot analysis revealed that c-Met/HGF receptor expression was stronger in the HGF-treated myocardium than in the non-HGF-treated myocardium after 8 hr of storage and was associated with a weaker expression of caspase-3 and a stronger expression of Bcl-xL after 60 min of reperfusion. Conclusion. The administration of rh-HGF before storage improved cardiac function after prolonged myocardial preservation by preventing apoptosis through the c-Met/HGF receptor. Thus, the addition of rh-HGF in the storage solution may be a promising strategy for prolonged heart graft preservation.

This study demonstrates the first synthesis of novel organic/inorganic ternary nanohybrids of tin(IV) prophyrin (SnPor), Ag nanoparticles (AgNPs), and reduced graphene oxide (RGO) by an environmentally friendly phtotcatalytic process using SnPor as a photocatalyst for the reduction of both GO and AgI. The nanohybrids exhibit high photocurrent generation as a result of the photosensitization effect of SnPor and surface plasmon resonance excitation in the AgNPs. Furthermore, in the activity test, the nanohybrids show good catalytic activity in the degradation of rhodamine B under the irradiation of visible light (?>400 nm) and in the reduction of 4-nitrophenol. The detailed mechanism is discussed in the article.


Automotive manufacturers require improved part load engine performance to further improve fuel economy. For a swing vane VGS (Variable Geometry Stator) turbine this means a more closed stator vane, to deal with the low MFRs (Mass Flow Rates), high PRs (Pressure Ratios) and low rotor rotational speeds. During these conditions the turbine is operating at low velocity ratios. As more energy is available at high pressure ratios and during lower turbocharger rotational speeds, a turbine which is efficient at these conditions is desirable. Another key aspect for automotive manufacturers is engine responsiveness. High inertia designs result in "turbo lag" which means an increased time before the target boost pressure is reached. Therefore, designs with improved performance at low velocity ratios, reduced inertia or an increased swallowing capacity are the current targets for turbocharger manufacturers.To try to meet these design targets a CFD (Computational Fluid Dynamics) study was performed on a turbine wheel using splitter blades. A number of parameters were investigated. These included splitter blade merdional length, blade number and blade angle distribution.The numerical study was performed on a scaled automotive VGS. Three different stator vane positions have been analysed. A single passage CFD model was developed and used to provide information on the flow features affecting performance in both the stator vanes and turbine.Following the CFD investigation the design with the best compromise in terms of performance, inertia and increased MFP (Mass Flow Parameter) was selected for manufacture and testing. Tests were performed on a scaled, low temperature turbine test rig. The aerodynamic flow path of the gas stand was the same as that investigated during the CFD. The test results revealed a design which had similar performance at the closed stator vane positions when compared to the baseline wheel. At the maximum MFR stator vane condition a drop of −0.6% pts in efficiency was seen. However, 5.5% increase in MFP was obtained with the additional benefit of a drop in rotor inertia of 3.7%, compared to the baseline wheel.Copyright © 2014 by ASME


The Rome Statute has made a compromise between the jurisdiction of the International Criminal Court (ICC) and the authority of U.N. Security Council, which indicates a nexus of equality and cooperation as well as a moderate restriction. Such a compromise, while mirroring the reality of international community and reflecting the separation and interaction of the judicatory function of the ICC and the political function of the U.N. Security Council, has its realistic rationality.

We showed previously that, after spinal cord injury (SCI), tumor necrosis factor-α (TNF-α) may serve as an external signal, initiating apoptosis in neurons and oligodendrocytes. To further characterize the apoptotic cascade initiated by TNF-α after SCI, we examined the expression of TNF-α, inducible nitric oxide (NO) synthase (iNOS), and the level of NO after SCI. Western blots and reverse transcription polymerase chain reactions showed an early upregulation of TNF-α after injury. A peak TNF-α expression was observed within 1 h of injury. By 4 h after injury, the expression of iNOS and the level of NO were markedly increased in the injured spinal cord. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling (TUNEL)-positive cells were also first observed in the lesioned area 4 h after SCI. The largest number of TUNEL-positive cells was observed between 24–48 h after SCI. Injecting a neutralizing antibody against TNF-α into the lesion site after injury significantl...


Traditional cultural expression (TCE) is an artistic heritage that is developed and maintained by the community or by individuals reflecting the traditional artistic expectation of the community. Traditional Cultural expression is one of the indigenous/traditional knowledge systems, the protection of which as creativity has been debated for the last four decades and still remains an unsettled and challenging issue to date. With the advent of new technologies, this matter has come to the surface raising not only as a legal matter but also, as a political concern in the context of international organizations. This study tried to analyze the necessity of granting protection for indigenous knowledge/indigenous TCE.
The researcher tried to analyze data from various literature, WIPO, ARIPO, and OAPI. Moreover, the researcher tried to analyze international and domestic legal regimes whether they protect TCE or not. Protection of TCE has not reached an agreement at the international level and it is also highly neglected in Ethiopia. There is no clear law that protects TCE in Ethiopia. Even at the policy level, there is no clear policy document that aspires for the protection of the indigenous knowledge system.
For sustainable economic development, Ethiopia shall enact indigenous customary law or sui generis legal regime for the protection of indigenous artistic and cultural knowledge

Finally, the speed and gait stability of the robot underwater and land are analyzed through lots of experiments.


Optimization of cultivation condition of recombinant E. coli DH5 alpha/pDH-B2m and the condition suitable for expression of recombinant mature peptide of human bone morphogenetic protein-2 was carried out in 500 mL shaking flasks and then transferred to NBS Bioflo IV, a 20 L DO feed-back fed-batch culture system, to obtain rhBMP-2. The results indicate that keeping dissolved oxygen at 40% and controlling nutrient feeding rate with DO feed back strategy can obtain theoretically 3.59 g recombinant mature peptide of hBMP-2 per liter of broth, the final cell density OD600 reaches 57(22.8 g dry cell weight/L), and the expression of rhBMP-2 amounts to 30% of the total protein in E. coli.


In this research the boundary controllability (boundary control) of three-dimensional micropolar elastic media using mathematical tool has been demonstrated. The advantage of the boundary control laws for boundary controllability problems was investigated. These control laws are simple and linear. For boundary control, the boundary observability for the dual system was utilized. For ordinary differential equations (ODEs), this method is standard but for the distributed parameter systems the proofs of the problem are based on a series of inequalities and mainly the boundary observability of dual system.


Internal combustion engines play a significant role in environmental pollution. In large cities, they are one of the main sources of toxic substances released into the atmosphere. One of the main tasks, along with improving the economic performance of diesels, is to reduce the toxcity of their exhaust gases. For these purposes, it is necessary to study the operation of diesels using alternative fuels. However, their use usually requires significant changes in the design of engines compared to diesels running on petroleum fuel. To study the main performance properties of ethanol-fuel emulsions as a substitute for petroleum fuels in the conditions of expanding the raw material base of automobile fuels and simultaneously reducing their negative impact on the environment, the Vyatka agricultural Academy continues to study the impact of alcohol use in diesels when they are fed using emulsions. The article presents the results of the research.


This paper concentrates on methods and techniques used to develop operational scenarios for orbital missions, including development of models to analyze alternatives, modification of tools and refinement of techniques for future missions. Many of these tools and techniques have been derived from previous tools, techniques and experience from the Orbital Maneuvering Vehicle (OMV) program. Results from use of these tools show the current Cargo Transfer Vehicle nominal mission scenario, with 95 discrete events defined for the CTV mission from the NLS Heavy Lift Launch Vehicle (HLLV) to Space Station Freedom (SSF).


This paper introduces a principal concept of MIMO bit division and presents its performance with corresponding simulation results. When multiple antenna technique is applied to enhance the spectral efficiency, the original data stream should be divided in a proper way. We found that the way of dividing original data stream, if it is not cooperating well with the originally structured system, may lead to performance degradation. The key idea is dividing the original data bit stream without causing an undesired change of bit order at the output of bit-to-cell demux.. Keywords—MIMO, MIMO bit division, DVB-T2, UHDTV.


Let D(Ω,Φ) be the affine homogeneous Siegel domain of type II, whose Silov boundary N is a nilpotent Lie group of step two. In this article, we develop the theory of wavelet analysis on N . By selecting a set of mutual orthogonal wavelets we give a direct sum decomposition of L2(D(Ω,Φ)), the first component A0,0 of which is the Bergman space. Moreover, we study the Radon transform on N , and obtain an inversion formula R−1 = (π)−2dLRL which is an extension of that by Strichartz [R. S. Strichartz, L harmonic analysis and Radon transforms on the Heisenberg group, J. Funct. Anal. 96 (1991), 350–406.]. We devise a subspace of L2(N) on which the Radon transform is a bijection. Using wavelet inverse transform, we establish an inversion formula of the Radon transform in the weak sense.


This article proposes a new approach for the use of poverty scoring in combination with credit scoring to classify borrowers using two axes: poverty level and creditworthiness.


Bcl-2 protein is an anti-apoptotic molecule overexpressed in many cancers 1 investigated both for its potential prognostic and therapeutic role. 2 – 6 Primary cutaneous follicle centre lymphoma (PC-FCL) represents 50 – 60% of all the cases of cutaneous B-cell lymphoma. 2 At immunohistochemistry PC-FCL expresses germinal centre markers such as Bcl-6, CD20 and CD79a. Although most cases lack BCL-2 expression, cases featuring BCL-2 expression both at mRNA and surface expression levels have been described. 2,7 – 10 However, it is not known whether BCL-2 + PC-FCL cases are associated with a higher risk of relapses. The present paper aims to evaluate whether Bcl-2 immunohistochemical expression correlates with a higher risk of cutaneous relapses in PC-FCL. We performed a retrospective search from the databases of the cutaneous lymphoma tertiary services of the Dermatology Units of Florence and Bologna. We selected all cases with a proven diagnosis of PC-FCL made between 01/01/2000 and 30/12/2019 with ade-quate clinical and histological data. We retrieved 128 patients, 77 males, 51 females, with a median age at diagnosis of 55 years. Median follow-up data were 126 months (range 12 – 384 months,). Sixty-nine (54%) lacked BCL-2 expression, 20 had a scarce (more than 10 but less than 50%) expression of BCL-2 (16%), 11 (8%) displayed more than 50% and up to 75% of the neoplastic infiltrate with an expression of the BCL-2 molecule, 26 (20%) had a positivity > 75% (Fig. in all cases.

After the road network in Tanzania had deteriorated, the Integrated Roads Project for 1990-2000 was set up. This was an ambitious programme to rehabilitate a large part of the road network, and formulate a maintenance regime, using the concepts of the World Bank's Road Maintenance Initiative. The current organisation of the Department of Roads still needs improvement. In 1994, the Management Action Group was established to address weaknesses and facilitate improvements. Its progress and plans are discussed here. Its work in human resource development is concerned with maintaining a staff database, including records of job descriptions and training, designing incentive schemes, providing professional development, and raising public awareness about the protection and safe use of roads and their furniture. Its work on institutional reform focuses on creating an autonomous road agency or authorities, and modernising road network legislation. Its work on systems development includes road network classificiation, and road inventory and condition database, and specific management systems. Its work on commercialisation is concerned with contractors and contracts. Although significant progress has been made since 1990, there is still considerable scope for improving the Tanzanian road network. For the covering abstract, see IRRD 890379.


Multimedia retrieval approaches are classified into three categories: those using textual information, and those using low-level information and those that combine different information extracted from multimedia. Each approach has its advantages and disadvantages as well to improving multimedia retrieval systems. The recent works are oriented towards multimodal approaches. It is in this context that we propose an approach that combines the surrounding text with the information extracted from the visual content of multimedia and represented in the same repository in order to allow querying multimedia content based on keywords or concepts. Each word contained in queries or in description of multimedia is disambiguated by using the WordNet in order to define its semantic concept.


This paper examines optical sensors that utilize the resonant modes within a Gires-Tournois interferometer. The sensor uses leaky wave type resonances present in structures composed of purely dielectric layers at the total internal reflection surface of a prism. This structure and experiment aims to test the refractive index sensitivity of the resonant structure which is due to the redistribution of the incident fields when the incident light is coincident with a resonance condition of the leaky wave structure.


A national survey of patient doses for diagnostic X ray radiographs is planned in Taiwan. Entrance skin doses and organ doses for all installed X ray machines will be investigated. A pilot study has been carried out for the national survey to develop a protocol for the dose assessment. Entrance skin doses and organ doses were measured by thermoluminescence dosemeters and calculated by Monte Carlo simulations for several X ray examinations. The conversion factor from free air entrance absorbed dose to entrance skin dose was derived. A formula for the computation of entrance skin doses from inputs of kV p , mA.s, source to skin distance, aluminium filtration, and generato rectifying was constructed Organ doses were measured using a RANDO phantom and calculated using a mathematical phantom. All data will be passed to the Atomic Energy Council for developing a programme of national survey and regulatory controls for diagnostic X ray examinations.


As CMOS device is scaling down significantly, the sensitivity of Integrated Circuits (ICs) to Single Event Upset (SEU) radiation increases. The Sensitivity of ICs to  soft errors emerge as reliability threat which motivates  significant interest in the development of various techniques both at the device and circuit level for SEU hardness in SRAM memories. To facilitate the scaling the concept of underlap Gate-Source/Drain (G-S/D) was suggested in the literature. L un is one of the sensitive geometrical parameter considered to differ from 1 nm to 5 nm in a SEU radiating environment. The effect of Gate-Source/Drain underlap (L un ) on soft error performance in 30 nm Junctionless Transistor (JLT) based on 6T-SRAM cell has been examined through extensive mixed mode-device and circuit simulations using TCAD. The critical dose observed in JLT based 6T-SRAM with L un ranging from 1 nm to 5 nm to flip the cell is given by Linear Energy Transfer (LET) between 0.05 to 0.06 pC/µm. The simulation result analyzes electrical and SEU radiation parameters to study its impact on JLT based 6T-SRAM cell.


Ernest Hemingway is one of the greatest American novelists. His For Whom the Bell Tolls, a novel on Spanish Civil War, is generally regarded as "his most ambitious artistic endeavor and a heroic epic of the 20th century American literature". The protagonist, Jordan, is a brave, unselfish, and stressful fighter for fascist, who is the more mature epitome of Ernest Hemingway in the reality. It is an example of application of "meta-fiction". Both of their views on war change from being pessimistic to being optimistic; both Hemingway and Jordan are the heroes of "Grace under Pressure" and both of them start to care for the society and love others.


The utility model discloses inner hole taper measuring equipment, which comprises a first length measuring device for acquiring the diameter of a bottom circle of a large end of a taper hole of a test piece, a second length measuring device for acquiring the diameter of a bottom circle of a small end of the taper hole of the test piece, a third length measuring device for acquiring the height of the taper hole of the test piece, and a taper calculating device calculating out the taper of the taper hole by utilizing the diameter of the bottom circle of the large end of the taper hole, the diameter of the bottom circle of the small end of the taper hole, and the height of the taper hole. In the inner hole taper measuring equipment, the diameter of the bottom circle of the large end of the taper hole of the test piece, the diameter of the bottom circle of the small end of the taper hole, and the height of the taper hole are respectively acquired through the length measuring devices, and then the corresponding taper is calculated out by the taper calculating device through using the three numerical values; and as the error introduced by the length measuring equipment is smaller than the error introduced by the traditional taper measuring equipment, the accuracy of the inner hole taper measuring equipment disclosed by the utility model is higher than the accuracy of the traditional taper measuring equipment.


The recent characterization of a von Wille-brand factor cleaving protease, now called ADAMTS13, was a major breakthrough in understanding the pathogenesis of thrombotic thrombocytopenic purpura (TTP). Congenital deficiency of ADAMTS13 causes chronic relapsing TTP, and acquired antibodies that


In this paper, we recall the principle of interference comparator for comparing end standards and using an additive polarization interferometer. Then, the length difference between two samples can be interpreted by the phase difference between two rectilinear vibrations which are polarized on two perpendicular directions. This phase difference is measured by the means of phase modulation. Owing to these concepts a display was imagined to assure the differential measure of thermal expansion. It is allowing to compare elongations of one sample and one standard. As the samples are magnetic materials measured under variable directions and force magnetic fields, it results a conception of interferometer taking account of sizes and characteristics of thermal expansion chamber. The assembled described display is allowing to show variations of optical phase with 10-8 relative uncertainly in terms of length differential variation.


In most network management systems, the Intrusion Detection System (IDS) is utilized to detect and prevent suspicious activity. IDS fundamental concept is to use feature values from the capture function of the network packet to classify when an action is irregular. The bulk of conventional classification algorithms, however, are unable to classify unfamiliar behaviors. As a classification algorithm for IDS, the algorithm proposed in this paper would combine clustering, classification, and metaheuristic algorithms to create a high-performance classification algorithm named search economics with k-means support vector machine (SEKS) and search economics with the intrusion detection system (SEIDS). The IDS technique might improve the attack detection accuracy rate by combining methods for unsupervised learning and classification. SEKS and SEIDS are two phases that can be separated from the proposed system. In addition, the suggested algorithm's hybrid methodology aims to improve the accuracy of detecting abnormal activity in such a system, reduce the classification algorithm's processing time, and allow the IDS in a network context to detect unfamiliar and novel variant assaults. In terms of accuracy, the suggested approach beats all previous classification methods examined in this research.


The in vitro activities of temafloxacin (A63004) and lomefloxacin (SC-47111; NY-198) were compared with those of seven other antibiotics against 146 isolates of bacterial enteric pathogens, including Campylobacter jejuni and Campylobacter coli. Ciprofloxacin was the most active drug against the Salmonella, Shigella, Yersinia, and Vibrio spp. tested. Lomefloxacin, temafloxacin, and difloxacin were the most active drugs tested against Campylobacter spp. (MIC for 90% of strains, 0.125 to 0.25 micrograms/ml).


Fundamental construction in public security grass roots is a necessary construction to improve the total forces. In the process, the construction should be connected with the practice to avoid one-sided awareness, single modal of work, free police resources allotment; moreover, target of the construction should be in accordance with the practice and the actual bearing capacity of the police; and also form and content of the construction have to be mixed to render the construction scientific, pragmatic; finally, the theoretical research and the practical analysis should grow up together to push the construction completely.


We study the relativistically expanding electron- positron pair plasma formed by the process of vacuum polar- ization around an electromagnetic black hole (EMBH). Such processes can occur for EMBH's with mass all the way up to 6 10 5 M. Beginning with a idealized model of a Reissner- Nordstrom EMBH with charge to mass ratio =0 :1, numerical hydrodynamic calculations are made to model the expansion of the pair-electromagnetic pulse (PEM pulse) to the point that the system is transparent to photons. Three idealized special rel- ativistic models have been compared and contrasted with the results of the numerically integrated general relativistic hydro- dynamic equations. One of the three models has been validated: a PEM pulse of constant thickness in the laboratory frame is shown to be in excellent agreement with results of the general relativistic hydrodynamic code. It is remarkable that this precise model, starting from the fundamental parameters of the EMBH, leads uniquely to the explicit evaluation of the parameters of the PEM pulse, including the energy spectrum and the astrophys- ically unprecedented large Lorentz factors (up to 6 10 3 for a 10 3 M EMBH). The observed photon energy at the peak of the photon spectrum at the moment of photon decoupling is shown to range from 0.1 MeV to 4 MeV as a function of the EMBH mass. Correspondingly the total energy in photons is in the range of 10 52 to 10 54 ergs, consistent with observed gamma-ray bursts. In these computations we neglect the pres- ence of baryonic matter which will be the subject of forthcoming publications.


Dissociative‐electron‐attachment cross sections for the production of OH−, O−, and H− from water vapor have been determined. These cross sections are discussed within the framework of resonance scattering theory. The relatively low cross sections for the production of OH−, 1.2, 0.85, and 0.85× 10−21 cm2 molecule−1 for maxima of 6.4, 8.4, and 11.2 eV, suggest that the atoms in the H2O− complex are loosely bound together and behave as essentially independent entities. All of the negative ions from H2O appear to be produced from three different electronic states of the molecule. Results from this study are used to draw a hypothetical potential energy diagram for H2O.


Ultrasonic motor's characteristics could change a lot in vacuum,as lacking of air.This paper described the motor's mechanical characteristics both in normal and vacuum condition with three friction materials,agglomerated-PTFE,unagglomerated-PTFE and epoxy-colophony.The max torque goes up in vacuum expect sepoxy-colophony,and the max speed all goes down.To find the reason,this paper give the dynamic friction coefficient's experiment and finded it increasing up in conventional,standing wave and travelling wave from normal to vacuum except sepoxy-colophony.Then,this paper tested the transient characteristics in vacuum,and finded the starting time and starting voltage grow up when the vacuum' degree went up to 10-2Pa.At last,this paper give the acoustic levitation force's numerical and fined it is about 1% in preload,which deserted the affect of acoustic levitation force in vacuum.The most factors which affecting the motor's mechanical characteristics are dynamic friction coefficient and the starting and run-time resistance.


In this paper we consider a single server queueing model with working vacation and multiple working breakdowns. When on vacation, the server works at a different pace. Disturbances occur in the server due to multiple breakdowns. In working breakdowns server works at a different rate. During the time of interruption caused by working vacation and working breakdowns, the main server can find many implementations in operation. Both the server's lifespan and the time it takes to repair it are considered to be exponentially dispersed. Also, we have considered balking and reneging behaviours of customers. The stationary queue length distribution is computed using a matrix-analytic technique. Using Genetic Algorithm (GA) we optimize the cost function. The predicted length of a busy period, the expected length of a working vacation period, the expected length of a working breakdown period, the mean waiting time, and the average delay are all established. We compute numerical results to verify the analytical point of view. The effect of individual parameters is investigated using sensitivity analysis.


We propose a converging algorithm allowing to reconstruct phase shifts in a broad range of momenta using low-energy scattering data and information about bound states (if supported by the potential).


Chittagong, the major port city of Bangladesh is seriously and violently vulnerable for landslide from geological and geographical point of view for many specific reasons. Along with the steep slope, slope cutting, natural weathering and antecedent rainfall causes for landslide of the city during the rainy season caused by thunderclap of heavy storms. This paper presents a quantitative analysis of slope instability problem of the Chittagong city by technical and mathematical analysis of Geotechnical properties of the region from laboratory measurement and modeling the selected vulnerable slopes using a different slope stability technique for circular slicing methods. The soil samples collected from the selected locations which show that the soils are medium to very fine sand consisting of medium to fine grains ranging from 37 to 57% with a tiny amount of silt and clay instance ~7%. Very low cohesive strength was observed for loose and dry samples. Angles of internal friction from 13° to 40° were determined while slope angles from 50° to 80° or more are measured distinctly. This steepness of the slopes is caused for landslide evident from the mathematical modeling. Most of the slopes beyond the friction angle of the slope will fail if the soil will be loosened. Modeling results also show that water pressure builds up within the soil of the slopes were mainly responsible for failure from the natural setting. To protect the slope from failure, the adequate supports have to be suggested which could enable to save the lives and properties of the vulnerable area of the city.

Evaluation of the effective acoustic pressure field of a continuous wave, optimum spaced, point source, annular cylindrical array for underwater pipeline inspection is featured in this paper. A section of the array comprised of m×n elements is selectively energized to illuminate the region to be tested and a similarly grouped set of remaining array elements function as receivers. A steady half‐power beamwidth and sidelobe levels were obtained for a radius of the array greater than 40λ. The portion of the energy reflected or reradiated from the contours of the pipeline and captured by the point source elements being nominally small can be neglected for all practical purposes. Effective acoustic pressure is computed as the Fourier transform of the impulse response of the array elements hmn(r,t) determined using the Green's function approach. The total effective acoustic pressure over the contour of the pipeline is the sum of the weighted contributions from all radiating set of elements. A good focusing effe...


In this study, detection of 20 FITC‐derivatized amino acids using an MEEKC‐LIF was demonstrated. In order to achieve good separation for hydrophobic amino acids, the MEEKC method was employed and detection limits were obtained in the range of 0.32–2.2 nM, which is comparable to previous reports on amino acid analyses. Furthermore, a significant reduction in the reaction time from 1 h for conventional derivatization to 3 min for the microwave‐assisted derivatization was observed and achieved, as opposed to the traditional pretreatment of real sample due to its complexity prior to the analysis of amino acid content. Finally, this microwave‐assisted derivatization MEEKC‐LIF method successfully determined amino acids in beverage, food, and biological samples (rat brain) with good recovery.


Effects of NaCl on relative growth, ion uptake and root tip structure were examined in four rice (Oryza sativa L.) cultivars with different salt sensitivity. Experiments were conducted to find the differences among the cultivars in salinity responses during seedling and more developed stages. NaCl was applied with nutrient solution at concentrations of 0, 25 and 50 mM for 7 days after germination or from 7th day after germination. Growth inhibition by salinity was more prominent in seedling stage than in developed stage. Root was more sensitive than shoot. Based on the growth, the order of sensitivity was IR24>Nipponbare>Nona Bokra>Pokkali. Sensitive cultivars IR 24 and Nipponbare accumulated high amount of Na and absorbed low amount of K and maintained higher Na/K ratios in roots and shoots under both stages than tolerant cultivars Nona Bokra and Pokkali. Relative growth of rice cultivars was negatively and significantly correlated with Na content and Na/K ratios in roots and shoots under both stages. SEM observation revealed that the root cap tissues proliferated and more layered and extended to the basal part of root tip regions. Effects on root cap structures were more prominent in early seedling stage than in developed stage.


Organizational strategies determine with which other businesses a firm will interact. However, organizational strategies are in part implemented through the interactions of the two businesses' boundary-spanning personnel. This paper uses Fiske's Relational Models Theory (Fiske, 1992, 2004) to develop an analysis of the interplay between the macro- and micro-level dimensions of business-to-business interactions. The analysis provides insights into the nature of an exchange that evolves through the macro- and micro-interactions which occur in organizational exchanges as they change over time.

The millisecond‐timescale, high‐efficiency modulation of upconversion luminescence via ultraviolet laser‐induced photochemical reduction of graphene oxide is reported. The luminescence tuning is achieved by combining a thin film of graphene oxide with lanthanide‐doped upconversion nanoparticles. The recovery of the graphene‐like structure through the photochemical reduction of graphene oxide is accompanied by a variation in the absorption coefficient of the as‐synthesized nanocomposite, which enables super‐quenching of the luminescence emission from the upconversion nanoparticles under near‐infrared laser excitation with values of up to ≈90%. Further, the instantaneous reduction in the emission intensity upon ultraviolet laser irradiation allows a 106‐fold decrease of the time for fast modulation of upconversion luminescence from up to tens of minutes down to milliseconds at microwatt‐level laser power. Optical patterning is successfully produced in the nanocomposite and individual pixels are retrieved distinctly with high spatial resolution through upconversion luminescence emission quenching by reduced graphene oxide. This method offers a superior avenue for controlling upconversion luminescence with high contrast, fast reaction speed, and low power consumption.


Conditions were studied under which aggregated complexes of histone F1 with DNA display a circular dichroic spectrum of nonconservative type characterized by two intense negative maxima at 269 nm and 209 nm. It was found that the intensity of the longwave band depends directly on the content of guanine plus cytosine and inversely on the molecular weight of DNA. The same type of dependence was found for DNA's of eukaryotic and bacterial origin. It appears that the formation of the nonconservative spectrum which can be ascribed to a certain structural form of DNA is caused by orientation of the DNA molecules in the aggregated complex and by specific interactions of the bases of the guanine–cytosine pair. The possible mechanism of formation of nonconservative dichroic spectrum is discussed with respect to special properties of guanine.


Abstract Durable materials for Nzi traps were tested in three applied settings based on promising formats that were tested first in Canada. Experiments were conducted at Cape Cod, Massachusetts, United States of America at the site of a major tabanid control programme and at two challenging tropical locations (Sudan and Philippines) where mechanical transmission of trypanosomiasis occurs. At Cape Cod, royal blue–painted plywood Nzi traps caught up to 19 times as many tabanids as greenhead box traps used locally did. Fabric Nzi traps caught up to six times more horseflies, Tabanus spp. (Diptera: Tabanidae), than a box trap did and twice as many horseflies than a popular commercial trap, the Horse Pal® did. A home-dyed phthalogen turquoise cotton trap also performed well. In the Philippines, it caught 2.5 times as many Tabanus as a standard phthalogen blue cotton trap did. Durable phthalogen blue Sunbrella acrylic and Top Notch polyester traps with various types of netting performed well at all locations.


An efficient hybrid method is presented to predict the shielding effectiveness of rectangular metallic enclosures with the finite thickness apertures on the front panels. The model is mainly divided into three regions: the half free space, slot waveguide and rectangular cavity respectively. The mode-matching technique and mixed potential integral equation based on the method of moments are applied to this model. The numerical results are validated by comparisons with those obtained by means of measurement. Furthermore, this method has been extended to account for the effects of finite thickness apertures and multiple apertures as well. The results of the shielding effectiveness varying with the thickness of apertures and multiple apertures have been given in this paper. Then the conclusions could be claimed that with the thickness of the apertures growing, the shielding effectiveness improves, and when a fixed area is divided into some small apertures, the shielding effectiveness can be improved too.

We exploit and clarify the use of random matrix theory for the calculation of the entanglement entropy of free Fermi gases. We apply this method to obtain analytic predictions for R\'enyi entanglement entropies of a one-dimensional gas trapped by a harmonic potential in all the relevant scaling regimes. We confirm our findings with accurate numerical calculations obtained by means of an ingenious discretization of the reduced correlation matrix.

The condition of the tourism sector in Bali during the COVID-19 pandemic tends to stop completely. This must  has an impact on theBali's economic growth and surely, it's not the right time to push the tax collecting for the government, particularly feom the tourism sector. In fact, the Indonesia's tax authority has issued a regulation regarding the policy of providing tax incentives during the Covid-19 pandemic. This study tried to assert the effectiveness of the tax incentives, especially for the income tax. The research was conducted using qualitative methods with interviewing the fiscuss and field observations. The results of the study indicate that the percentage of the MSME taxpayers in the tourism sector, who utilize the tax incentives, reaches about 43.10%. The main reason,why the achievement is so shirt, are because taxpayers feel burdened with reporting administrative requirements.


Power Quality measurements have been performed in two Norwegian MV networks which both have a limited amount of distributed generation connected. The measurements indicate that the generation units do not cause power quality problems. The results are however not directly transferable to networks with higher share of distributed generation.


The lack of knowledge, perceptions and wrong attitudes in society about drugs causes irrational use of drugs. This research aims to assess the perceptions, knowledge and attitudes of non-health students about medicine at the University of Muhammadiyah Magelang. The design of this study used a cross sectional survey with a questionnaire as a research instrument. The sampling technique used is convenience sampling. A total of 107 respondents were used in this study. Perceptions, knowledge and attitudes of non-health students of the Universitas Muhammadiyah Magelang are good. However, the provision of information and education still needs to be done continuously so that non-health students' knowledge of medicine increases.


Morphological analysis is always considered as an important task in natural language processing (NLP). Lemmatization is a major morphological operation that finds the dictionary headword/root of a surface word. In context sensitive languages, the context of a surface word plays a key role to find its lemma. So far, a limited number of neural lemmatizers have been developed for in-context lemmatization and these models account the entire sentence as context. In this research, we hypothesize that a limited context is sufficient for lemmatization and thus, make use of the convolutional neural network to accomplish the task. Our proposed BLSTM-CNN lemmatizer is evaluated on four languages, two Indic (Hindi and Marathi) and two European (French and Spanish) ones. The experimental results show that consideration of smaller context indeed achieves better performance over the approaches considering whole sentence as context in determining lemmas of surface words.
