Wetlands are among the most productive ecosystems in the world. Urban wetlands are increasingly affected by population growth and developmental activities. A buffer region of 60 m from the Bolgoda lake boundary was gazetted as an Environmental Protection Area (EPA) by the Central Environmental Authority in 2009 as it is the largest freshwater wetland in Sri Lanka. This study attempts to quantify the land use changes during the period of 2001 to 2019 using GIS and to identify the 'hot spots' where a significant change in land use occurred. Land use/land cover (LULC) changed in the Bolgoda wetland area disproportionately. The greatest proportion of loss of natural area was observed in dense vegetation, where a 63.35 % decrease was apparent from 2000 to 2019. In contrast, the residential and commercial areas increased and in 2019 the change reached 49.62 % and 68.57 %, respectively. Hotspots were identified at Grama Niladhari divisions that belong to Kesbewa and Bandaragama DS divisions with the largest change in LULC. Thus, the results of the investigation provide vital information for the conservation and sustainable use of wetland resources in a rapidly expanding urban landscape.

Introduction Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a rare entity with distinct clinico-pathological features accounting for 5% of all Hodgkin lymphomas. Its optimal management is still debated, including the place of therapeutic abstention, and the role of rituximab. With the aim to report the management of the disease in a large series of patients (pts), we performed a retrospective study describing the characteristics of NLPHL at diagnosis, the therapeutic strategies, outcomes and the risk of late complications, including secondary malignancies. Methods We retrospectively analyzed adult pts with NLPHL treated in the Lymphoma Study Association (LYSA) centers between 1974 and 2012. Survival analysis were made according to the log-rank regression model. We also performed a competing risk analysis in order to better assess the risks of death, progression and secondary malignancies. Results 314 pts, out of a total of 366 were retained for further analysis. Median age at diagnosis was 38 years. Most pts (82.5%) presented with localized, Ann Arbor stage I-II disease. Watchful waiting (WW) was the most frequent attitude at diagnosis, and concerned 114 pts (36%), mainly with localized disease (104 pts). 200 pts received a treatment, which comprised chemotherapy +/- rituximab for 68 pts (34% of pts with treatment), radiotherapy for 63 pts (31.5%), combined modality treatment (CMT, chemotherapy +/- rituximab followed by radiotherapy) for 40 pts (20%), and rituximab alone for 28 pts (14%). Among 155 pts with localized disease who received initial treatment, radiotherapy alone was delivered to 62 pts (42 with stage I, 20 with stage II disease), mainly on the cervical, supra-clavicular or axillar areas. The radiotherapy fields included the mediastinum in 7 localized pts treated by CMT. Among 55 pts with disseminated disease receiving initial treatment, chemotherapy +/- rituximab was administered to 32 pts. Most of them received anthracycline-based chemotherapy, and ABVD-derived chemotherapies were the preferred regimens with 19 pts; 8 pts received CHOP-like regimens. With a median follow-up of 55.8 months, 112 pts relapsed or progressed. Among them, 37 pts (33%) received chemotherapy +/- rituximab, 27 pts (24%) radiotherapy alone, 19 pts (17%) rituximab alone, 7 pts (6%) CMT, and 2 pts rituximab + radiotherapy. WW concerned 19 pts (17%) at first relapse/progression. The overall response rate (ORR) for the whole population was 83%, with 200 pts (79%) reaching CR or CRu, 3 months after diagnosis. The CR/CRu rate according to the different treatment modalities were 95% for radiotherapy alone, 89% for rituximab alone, 87% for chemotherapy +/- rituximab and 91% for CMT, respectively. In localized disease, 40 pts had persistent CR/CRu after radiotherapy alone. In disseminated disease, 45 pts who attained CR/CRu after chemotherapy +/- rituximab did not subsequently relapse. The median PFS for the whole population was 112.1 months. There was no impact of Ann Arbor stage on PFS, but the attitude at diagnosis had a powerful impact. Compared to WW, the risk of progression was significantly reduced for pts treated by radiotherapy alone (Hazard ratio: 0.345 [95% CI: 0.196; 0.610], p = 0.0002), chemotherapy +/- rituximab (HR: 0.476 [0.266; 0.855], p = 0.0129), or CMT (HR: 0.292 [0.148; 0.577], p = 0.0004), but not with rituximab alone. The risk reduction remained significant for pts who had complete surgical resection of the initial lesions and received any additional treatment vs pts who were just watched after surgery (HR: 0.344 [0.122; 0.974], p = 0.0444). The estimated OS at 72 months is 96.9%. OS was not different according to the attitude at diagnosis, including WW. 10 pts died, 1 due to lymphoma progression, 5 of secondary malignancies and the remaining 4 of accident or unknown causes. The competing risk analysis model confirmed that the risk of relapse/progression was significantly reduced with radiotherapy in stage I-II pts (HR : 0.474 [0.277; 0.812]), and with a treatment combining chemotherapy +/- rituximab +/- radiotherapy in the whole population (HR: 0.388 [0.234; 0.643]). Conclusion Our study supports the use of radiotherapy in localized disease, and of treatments combining chemotherapy +/- rituximab +/- radiotherapy, to improve disease control in adult patients with NLPHL. Disclosures No relevant conflicts of interest to declare.


As successful tourism firms invest heavily in marketing to defend or improve their competitive position, they increasingly need to measure their marketing performance. Previous studies related to tourism have largely focused on financial and operational performance, but the marketing perspective has been largely overlooked. Drawing on an in-depth investigation involving 12 hotel chains, 8 travel agencies and 8 tour operators, this study provides an overview of the state-of-the-art marketing performance measurements among some of the leading tourism firms in Italy. Several issues and unanswered questions are also identified.


Different Chinese translations are required for the multiple meanings of legitimacy.Translators shall give up nomenclatural anticipation of "100% correspondence "or "all meanings included"in Chinese translation. As a key word or key term in political philosophy,legitimacy can be translated as"hefaxing""zhengdangxing",and so on. However,"hefaxing"is not proper because it is also the translation of "legality"; "zhengdangxing"is not proper because it is also the translation of"justness"and"justification". The basic meaning of legitimacy is that regime or government is accepted and admitted by people,so "kenrenxing"or "renshouxing"is the most appropriate translation.


A new identification and indexing for the phase BaAl2Ti5O14 were accomplished using an X-ray diffraction technique. The new lattice parameters for the tetragonal lattice structure are: a0=9.990 × 10-10 m and c0=12.264 × 10-10 m, with a corresponding volume 1.224 × 10-27 m3. The data provided by the Joint Committee on Powder Diffraction Standards are inconsistent both in lattice parameter values and Miller indices. The X-ray powder diffraction pattern of BaAl2Ti5O14 was indexed using the LSUCR (least-squares unit cell refinement) computer program.


The microscopical pattern of rest-budding in UV or peroxide treated yeast cells was studied in strains of different ploidy. UV-irradiation caused in all investigated strains a very similar pattern, i.e. by a given effective dose, measured by the macroscopical survivals, approximately the same final frequencies of more than one and also of more than three cells in a clone could be observed in all investigated strains. It seems possible to explain these results by a non-strain-depending dose reduction factor of 2.2: 1 for the frequency of more than one cell, and 1.2: 1 for the frequency of more than three cells, both related to the commonly used macroscopical survival frequency curve. The dose reduction by photoreactivation was approximately 2: 1 and caused a corresponding shift of the microscopical pattern. After treatment with organic peroxides the microscopical pattern in haploid strains was very similar to that after UV-treatment, although there was no photoreactivation. In diploid strains there is a characteristical different pattern with nearly none rest-budding even in a strain produced by self-diploidization. These results are discussed in their bearing on possible inactivation mechanisms


Summary form only given. We have observed indirect, picosecond heating of solid targets from high intensity (>1017 W/cm 2), ultrashort pulse (500 fs) laser pulses. The study was performed on foil targets consisting of 1000 Aring Al and 12.5 mum Ti. The targets were illuminated from the aluminum side to eliminate direct laser heating of the Ti foil. Time-resolved measurements of the Ti Kalpha (2.749 Aring) were made using a sub-picosecond X-ray streak camera interfaced to a von Hamos crystal spectrograph. In addition to the time-resolved Ti Kalpha data, a spherical crystal, X-ray imaging spectrometer was fielded to determine the emission region of the Ti Kalpha and an electron spectrometer was used to observe the non-thermal electron distribution. Finally, the spectrally resolved backscattered laser light was observed to help determine if laser-driven instabilities produce the hot electrons. The data will be presented along with a preliminary interpretation of the results

A case of mediastinal hemangiopericytoma is presented.Hemangiopericytoma is a rare tumor and in Japan there have been only 210 cases since Ohta first reported it in 1913. This tumor consists of pericytes and shows a characteristic pattern with reticulin staining. Although these tumors can exist in any part of the body, most of them occur in the lower extremities and retroperitoneal space.Tumors in the mediastinum are extremely rare. CT and angiography are useful in diagnosis. The best treatment for this tumor is surgical removal. Radiation therapy and chemotherapy are not effective. The survival rate in these patients is inversely proportional to the size of the tumor. In our case, the patient has survived one year without disease.


Representative Agent Equilibrium Models (RAEMs) are standard, still very popular, simplifying yet powerful, theoretical frameworks. They match by simulation a growing number of empirical moments but their ability to t actual data is still quite poor. This study provides a formal setup to analyze what is systematically wrong with these models and how to potentially ameliorate them. Unsurprisingly RAEMs do not work during bad times, characterized by very high levels of market frictions, medium-high information asymmetry, medium-low market demand where aggregate expectations are not rational. Perhaps less obviously and more generally, the probability of RAEMs failures is found counter-clyclical and always quite high, with market frictions being more problematic during recessions and information asymmetries during normal times. The main contribution of this paper is to give a novel, uni ed and constructive explanation for this ndings: the tension of RAEMs in matching the unconditional risk premium makes them over-estimating the risk premium in bad times (and potentially under-estimating it in normal times). This is because in bad times investors are over-optimistic and require a too low compensation for bearing the market risk while in normal times they are over-pessimistic. Equilibrium models featuring informational ambiguity can accommodate this new facts. *Olin Business School, Washington University in St. Louis, Email: email@example.com.

AbstractThe small areas of white metallic pigment seen on the south wall of J. M. Whistler's 'Peacock Room' in the Freer Gallery of Art are platinum; this has been used, with a yellow-brown ground, to overpaint a preceding layer of silver which, in one place only, is over a preceding layer of gold. The yellow metallic pigment is confirmed as gold and the blue colour of the south wall and elsewhere is based on Prussian blue. On a separate wood panel a green was tentatively identified as copper resinate, and iron-oxide-based pigments appear to be present. In all areas investigated a white, used as a ground and in admixture, was essentially lead white and calcium carbonate. The significance of these results is discussed briefly.


This paper describes fundamental logical and arithmetical calculations carried out on the molecular level using DNA solution. In our approach specific mapping of logic signals into DNA strands is assumed. Appropriate DNA sequences are applied to represent both logic states. The design and operation of a molecular flow-cell has been described in detail. The XOR logic gate is considered. The implementation of a Moore's automaton realizing for sample graph has been presented, where growing size of input and output alphabet as well as number of states results only in increasing number of components while the design methodology remains the same. It has been mentioned that lab-on-a-chip type devices that allow automation of sequential DNA processing can realize the functionality of molecular flow-cell. Such flow-cells may play an important role in construction of future computing hardware.


Field experiment was conducted during 2015 cropping seasons to evaluate of row intercropping Maize with Common Bean. The experiment was laid out in randomized complete block design with four replications. The results  showed that the yields of maize and haricot bean  from  the  treatment ( one Maize: two Common bean ,one Maize: one common bean, maize sole and Common bean sole)  produced  55.6q/ha:17.2q/ha ,43.3q/ha: 26.4q/ha and61.1q/ha 27.2 q/ha  yield ,respectively.  Therefore one maize: one Common bean of row intercropping was superior to other intercropped treatments. The LER and MAI indicating the practice of intercropping of one Maize with one Common bean was more advantageous than the conventional monoculture crop. Even if significant yield difference was not observed for sole maize and haricot bean among the treatment, one maize intercrop with    two   common bean proportion with LER of 1.54 and MAI of 12,609   and one maize mix one Common bean proportion with LER of 1.68 and MAI of 15559 Proved to be best than planted at sole indicating the practice of   one maize with one haricot bean intercropping was more advantageous and profitable than the conventional monoculture crop .


Introduction: Enhancing nursing students' critical thinking is a challenge faced by nursing educators. This study is aimed at determining the effect of clinical concept mapping using nursing process on discipline based critical thinking of 4th year nursing students. Methods: In this quasi-experimental study, a convenient sample of 32 nursing students participated. They were randomly assigned to two groups. The control group was involved just in the usual clinical practice, while the experimental group participated in a one day workshop on clinical concept mapping using nursing process during their usual clinical practice. They were also asked to provide at least two clinical concept maps during their clinical practice. On the 10th week of their clinical practice a post-test was done using a specially designed package consisting of fourteen vignettes and three open response opportunity for measurement of seventeen dimensions of critical thinking in nursing (under two categories of cognitive critical thinking skills and mind habits). Students of both groups were required to write about how they would use a designated critical thinking habit or skill to act in a certain way. The students' responses were evaluated by two raters based on identification of critical thinking, justification and quality (appropriateness of the responses with regard to their level of education) of the student's response. The mean scores of both groups were compared by Mann-Whitney test. Results: Result of the study revealed a significant difference (p<0.001) between the two groups' cognitive critical thinking scores: Experimental group mean score (20.14±13.62) vs the control group mean score (6.41± 6.52).The results also revealed a significant difference (p<0.005) in the scores of mind habits: Experimental group mean score (23.68±20.58) vs the control group mean score(6.30± 5.51). Two groups of study were also significantly different from each other in 11 out of 17 dimensions of critical thinking (p<.01). Conclusion : Teaching and application of clinical concept mapping leads to improvement of critical thinking abilities in nursing students. However, further studies are recommended to generalize this result to nursing students in their earlier stage of education.


The problems of a possible curvature dependence of surface tension and its effect on the general scenario of nucleation processes are investigated. It is shown that practically all particular expressions for the curvature dependence of the surface tension of droplets (and bubbles) in one-component vapors (liquids) proposed so far may be obtained from one general ansatz for the Tolman coefficient by assigning appropriate values to two parameters. Moreover, criteria are given for determining the conditions under which the results can be extended to multicomponent systems. Based on these results it is shown that the account of a curvature dependence of surface tension may indeed result in significant variations of the work of formation of critical clusters, although a number of attempts made so far in determining this effect can be considered only as approximations. However, in contrast to earlier expressed opinions we show that at present no convincing evidence exists allowing a conclusion that the account of a curvature dependence of surface tension may lead to qualitative changes of the scenario of nucleation processes as characterized first by Gibbs and used as a starting point in practically all theories of homogeneous nucleation.


Abstract Translation of long sentences in English is a complex problem in machine translation. This work briefly introduced the basic framework of intelligent machine translation algorithm and improved the long short-term memory (LSTM)-based intelligent machine translation algorithm by introducing the long sentence segmentation module and reordering module. Simulation experiments were conducted using the public corpus and the local corpus containing self-collected linguistic data. The improved algorithm was compared with machine translation algorithms based on a recurrent neural network and LSTM. The results suggested that the LSTM-based machine translation algorithm added with the long sentence segmentation module and reordering module effectively segmented long sentences and translated long English sentences more accurately, and the translation was more grammatically correct.

Archival recovery, especially of memory threatened by dictatorships or totalitarian regimes, is always a pressing task. The recovery of the Edgar Leuenroth archive at the Universidade Estadual de Campinas, considered the most valuable set of documents on the workers' movement during its unionization phase, involved many intellectuals and institutions. To accompany the reasoning and life-paths of those who realized the sheer importance of this archive and endeavored to preserve it is a worthwhile pursuit.


This mixed-methods study, with an emphasis on quantitative data collection, shed light on the impact of independent choice in a Sustained Silent Reading (SSR) program on students' comprehension and feelings about reading. It used one Ninth Grade General Level English class, approximately 21 students overall, in which they received the SSR intervention. Data was collected through surveys, released SOL reading comprehension questions, interviews, and teacher observations. The findings showed that students who participated in SSR with an emphasis on independent choice in reading material made minimal gains in reading comprehension, and ultimately, positively increased students' perceptions of reading. In an effort to counter the National Reading Panel's (2000) finding that SSR had no impact on student comprehension and encouraging students to read is not reflected in student achievement. INDEPENDENT CHOICE, SSR, & COMPREHENSION 3 Reading has become a mundane skill that gets shoved into backpacks, obligatorily written in agenda books, and pushed under beds. With such a push from standardized assessments and measurements, students do not see the importance or relevancy of reading in their everyday lives. In my time as an English student and teacher, I have encountered such phrases as, "Why do we need to read this?" "Why can't we read something interesting?" "Why can't the curtains just be blue?! Why does it have to mean he is sad?!" While they may seem like exclamations from students who simply do not want to do work or those that hate being stuck in the monotonous routine of school, these questions actually offer a strong insight into the role of reading in the classroom. Due to my personal interest in English, I have developed a fascination with finding the hidden significance behind making the curtain mean something more or explaining the symbolism behind the green light in The Great Gatsby. Mottel (2011) stated that, "for students who don't care about the green light or what it means, it could be torture, especially if this is a question that is gathered with 30 other questions on a worksheet, back and front" (p. 33). Reading has become a chore; the same texts are taught each year; the same standardized tests measure comprehension. With the looming presence of high-stakes testing, reading has become "read this passage and answer the following questions" with no regard for student interest or opinion. Yoon (2002), Ivey and Johnston (2013), and Kasten and Wilfong (2007) all acknowledged that student engagement and motivation to read are impacted when the materials are relevant to students' lives. Students appreciate when they are given a choice; they appreciate when something is personally relatable. One way to give students this sense of autonomy in their learning is through the implementation of a Sustained Silent Reading (SSR) program in which INDEPENDENT CHOICE, SSR, & COMPREHENSION 4 students have, for the most part, complete independent choice in their readings. Generally, SSR programs allowed students to read a book for a set amount of time either at the beginning or end of a class period. The idea was to give students a chance to read for "fun" and develop a stronger relationship with the reading process. However, SSR, for the most part, has been an effective way to encourage reading and thereby reading achievement. According to the National Reading Panel (2000) report, fluency in reading is the gateway to student comprehension of texts. The report compared the impact of Guided Oral Reading (GOR) and the implementation of Sustained Silent Reading (SSR) in the classroom, finding that SSR had no influence on students' reading comprehension and encouraging reading had no effect on reading achievement (National Institute, 2000). Because of such findings, GOR became the primary mode of reading instruction; therefore, placing an emphasis on fluency measurements. The measurement of fluency is defined as "the ability to read a text quickly, accurately, and with proper expression" (National Institute, 2000, p. 3-1), and ultimately, it "has been described as the 'most neglected' reading skill" (National Institute, 2000, p. 3-1). Due to this neglect of fluency, and the success of GOR, silent reading has been placed on the backburner as a mode for promoting reading and comprehension. In spite of the National Reading Panel's findings, silent reading has drawn much debate about whether or not these methods are an effective measure. Most research viewed the ability to read expressively and with speed as the critical components of fluency and mastery of reading skill; however, it has also served as a catalyst for studies on the impact of SSR in the classroom. While students' reading comprehension skills are a vital component of reading in the classroom, the National Reading Panel's (2000) findings highlighted an issue with most reading comprehension measurements. INDEPENDENT CHOICE, SSR, & COMPREHENSION 5 Therefore, the research question is as follows: What impact, if any, does independent choice in a Sustained Silent Reading program have on student comprehension and overall feelings about reading? The purpose of this research is to determine whether full independent choice in a Sustained Silent Reading (SSR) program promotes positive feelings about reading and thereby influences students' comprehension due to engagement and motivation to read.


A new geometry-based stochastic scattering model (GBSSM) for wideband multiple-input-multiple-output vehicle-to-vehicle (V2V) channels is proposed in this paper. The proposed GBSSM with cross-polarized antennas combines three-dimensional two cylinders to model the stationary scatterers and two-dimensional multirings to imitate the moving scatterers. The channel realization by using the channel matrix in this paper is much more straightforward and concise to study the channel characteristics compared with the too complicated analytical solutions available so far. Because V2V propagation channels are nonstationary, the time-varying channel properties and parameters are further investigated based on the proposed GBSSM and realized channels, which can be used in the link and system-level simulations in V2V radio systems.


AIM
To evaluate prognostic value of 24-h monitoring of blood pressure (BPM-24) for assessment of structural changes in arterial walls in patients with essential hypertension living in West Siberia.

MATERIAL AND METHODS
In the course of 5-year prospective study we made two extended clinical and device examinations with use of BPM-24 and ultrasonic measurements of arterial intima-media complex (IMC) in 160 patients (mean age 48.97+/-8.18 years).

RESULTS
An independent significant correlation was found between initial drop of the circadian index (CI) of blood pressure, systolic blood pressure (SBP)/diastolic blood pressure (DBP) at night (r = 0.24/0.22, p = 0.012/0.024) and thickness of IMC in 5 years (r = -0.28/-0.30, p = 0.004/ 0.002). The risk of increased thickness of arterial wall in the group with abnormal CI was 1:4. There was no relationships between IMC increase and baseline office blood pressure (r = 0. 18/0.12, p = 0. 057/0.188). In evaluation of office BP effects on progression of arterial atherosclerosis insignificant correlation coefficients for SBP/DBP were obtained (r = 0. 18/0.18, p = 0. 150/0.149) contrary to BPM-24 parameters: mean circadian SBP (r = 0.22, p = 0.046) and heart rate (r = 0.23, p = 0.038), SBP temporal index for 24 hours (r = 0.24, p = 0.035).

CONCLUSION
. BPM-24 parameters are more significant predictors of structural changes in arterial wall than standard office blood pressure. This allows calculations of possible risk of such changes.

The inspection of surface hardness of the hardened steel is important in keeping the quality of automobile parts, etc. The permeability of hardened steel decreases when the hardness is increased. Therefore, the surface hardness evaluation is possible by detecting the difference of the magnetic characteristic using the electromagnetic inspection method. However, the surface hardness inspection is not easy, because the relative permeability and conductivity of the hardened steel are usually nonuniform compared with that of the normal steel. In this paper, the technique for reducing the effect of the nonuniformity of the permeability and the conductivity on the large magnetic noise, and measuring the surface hardness is examined using three-dimensional edge-based hexahedral finite element method. In addition, the experimental verification is also carried out.

Talk about the rich arsenal of decorative and artistic variations in the traditional living architecture, consider the symbolism originated in the traditions. The decorative equipment of residential buildings is determined by the indicator of the quality and originality of the glorification of the national culture, which will support the relevance of the development of cultural development and illumination of symbols. About the formulation of architectural and artistic plastics of facades and a look through the prism of architectural symbolism, about reading the information code embedded in symbols, is known in the monographs of A.O. Kadurinа. The creation of links between elements of ornamental motifs, as well as visual and morphological regularities - in the scientific works of I.A. Yurchenko. Problems of ethnic self-identification in the multicultural space and the root of art methods in the architectural design of the middle ground - the article of O.M. Tyurikova. Purpose of the article: to conduct a detailed and comprehensive analysis of symbol complexes in the traditional architecture of central Budzhak: the tree of the world, symbols of fertility and status. The image of the tree of the world and the symbols of natural elements (sun, water, earth, midwife) immediately formed a group of symbols of the universe (65.2%). Prior to the symbols of fertility (28.3%), the following are included: fruit, steams, wheat, grapes, kits, garlands of leaves, kits and fruits, vases with kits and fruits. Status symbols (6.5%): heraldic lines, cartouches with initials and the date the house was built. People's majstri introduced the first and most important ideas of the establishment of the world, the greatness of the ministers of Vsesvit, as well as the power of natural forces. The presentation of the decorative and artistic features of various symbols and symbols in the traditional architecture of central Budzhak encourages design with elements of ethno-art traditions. The location of the symbols (the tree of peace, symbols of fertility and status), both on the house itself and in the middle of the estate, is determined by the idea, meaning, as well as constructive and compositional features.


Charley is ambivalent and patchy, yet compelling in its incompleteness. A discussion of what the power of pragmatic thought and discourse might mean, or, as might be the case, whether it would have any relevance at all, for a character that doesn't fit the classic Frank Bascombe prototype (intellectually gifted, emotionally articulate, and existentially troubled male) would have made the book more inclusive and interesting. Both Knapp's and McGuire's books, and the University of Iowa Press's New American Canon series, are part of the growing interest in recent American fiction, and in writing that, while having been widely reviewed and critically acclaimed, has not yet been the subject of critical analysis. The series' focus on contemporary 'realist' writing (pragmatist realism of Ford in McGuire's book, capitalist realism in Alison Shonkwiler and Leigh Claire La Berge's edited collection, regional cosmopolitanism in Violet America, and the fiction of the ordinary everyman in Knapp's work) rethinks the realism-experimentation debate that has evolved: it is not just a question of whether fiction is a mirror to reality, but a critical, and even slightly sceptical, appraisal of whether fiction can be trusted to find meaning in the ordinary environment and show us the best way to live now.

Background: Respiratory complications have been the main cause of death after a resection of esophageal cancer. This retrospective study was conducted to investigate the effect of thoracic epidural analgesia on respiratory complications after a resection of esophageal cancer. Methods: This study enrolled two groups of patients undergoing an esophageal resection during a 7-year period. The first group (control group) was comprised of 105 patients in whom thoracic epidural analgesia was not used. The second group (epidural group) was comprised of 121 patients in whom thoracic epidural analgesia was done routinely. The latter group received an initial bolus of 0.1% bupivacaine 10 ml with 2 mg of morphine at the end of surgery and an infusion of 2 ml/hr of the solution comprised of 0.1% bupivacaine with 0.2 mg/ml morphine for 3 days. The incidence of respiratory complications and the duration of ventilator care and ICU stay were investigated by reviewing of charts. Results: There were no significant differences in the incidence of respiratory complications and the duration of ventilator care and ICU stay in both groups. Conclusions: The results of this study suggest that the routine use of thoracic epidural analgesia did not reduce the incidence of respiratory complications after resection of esophageal cancer.


This is Presents experimental results of a force tracking controller for a quarter-car suspension system. The active suspension system was decomposed into two loops. At the main loop, the desired force signal is calculate by using a standard LQ design process. The Time Delay Control(TDC) design technique is then used to design the force controller such that the desired force signal is achieved in a robust manner when actuator or other plant uncertainties are present. The ADAMS controls module was used to realize the joint simulation of ADAMS and MATLAB, of which the results showed that the TDC strategy is reasonable and feasible.


The author links the spreading of the cult of St. Peter on the Piast lands with the specific political-cultural situation of the newly emerging state organism. It was a situation when the choice of an appropriate patron was in fact a tactic measure with far reaching consequences. The article presents a logical sequence of historical developments which would eventually lead to entrusting the state to the protection of this special saint. The author also mentions the active cult of the saint and focuses on the image of the sword of St. Peter, referring in this context to a miniature from the "Gniezno Codex" with a representation of the scene in the Garden of Olives.


Aseel, a popular breed of native chicken, characterized by its pugnacity, fighting strength and royal gait is being used to create crosses for domestic chicken production. However, information on its growth models is scanty. An experiment was conducted to evaluate different non-linear models and to find out best fitting model in Aseel, being maintained at Central Avian Research Institute, Izatnagar, Bareilly. Data on body weights from 12-weeks of age to 20-weeks of age at biweekly intervals were recorded on a random bred single-hatched flock. Owing to the non-linear characteristic of growth, three non-linear models namely, Gompertz, Bertalanffy and Logistic models were evaluated. Goodness of fit for all the models were checked using coefficient of determination (R2), adjusted coefficient of determination (Adj-R2), mean square error (MSE), mean absolute error (MAE) and Akaike information criterion (AIC). The Bertalanffy model most accurately characterized the growth trend in males, females and pooled sex data. The study revealed that this model may be used to ascertain the average body weights in Aseel chicken under random mating. The investigation has generated baseline data on growth modelling of random bred groups and may be used in similar investigations on other native chicken breeds.


The thickness of the material can be thinned because arch cut-and-cover tunnel has the support mechanism by the axial force, and the ground reaction force due moderate deformation can be expected thereby making it be dynamically advantageous, therefore the arch cut-and-cover tunnel has become more widely used. An important characteristic of the arch cut-and-cover tunnel is that the thickness of the material can be thinned because precast arch type has the support mechanism by the axial force. However, there is a different stress state surrounding the structures between normally excavated tunnels and cut-and-cover tunnels, it should be considered at designing. Therefore, finite element method was carried out to examine the mechanical behavior of the precast arch cut-and-cover tunnel considering construction procedure.


Carrier aggregation was introduced to Long Term Evolution Advanced in order to improve the performance especially in terms of a higher peak data rate. When employed, sets of user equipment will have a set of serving cells, which includes a Primary cell (PCell) and Secondary cells (SCells). For inter evolved Node B (eNB) handover, target eNB is selected only consider the channel condition of the PCell. Thus, a suitable set of serving cells cannot be selected. In order to address this problem, this paper proposes three handover methods considering channel conditions for multiple cells. Methods 1 and 2 adjust the handover margin according to the difference in channel conditions between the PCell and SCells for the serving eNB. Method 3 decides handover based on equivalent channel conditions for the PCell and SCells in both the serving eNB and neighboring eNBs. Simulation results show that the proposed methods provide higher cell-edge throughput and a much smoother handover at the cost of a slightly increased number of handovers.


Fedorov P., Grabic R., Fedorova G., Cosson J., Boryshpolets S., Dzyuba B. (2017): Development and application of LC/HRPS for quantification of adenine nucleotides, creatine phosphate, and creatine in sturgeon spermatozoa. Czech J. Anim. Sci., 62, 67–74. The objective of this study was to investigate the applicability of liquid chromatography coupled with high resolution product scan (LC/HRPS) mass spectrometry for simultaneous quantification of adenine nucleotides, creatine phosphate, and creatine levels after fixation of sturgeon sperm by perchloric acid. This approach has been used for the determination of adenine nucleotides, creatine, and creatine phosphate in biological tissues, but no applications to sperm cells have been reported to date. The results of method validation showed that specific correction factors for the calculation of macroergic phosphate content in sperm cells extracted by perchloric acid should be used to get accurate concentration values. The proposed LC/HRPS method is beneficial for the analysis of adenine nucleotides because it allows simultaneous quantification of all target analytes at low concentrations in a single run. This is an advantage compared to conventional methods based on colorimetric or chemiluminescent assays and even compared to sophisticated methods based on high resolution nuclear magnetic resonance.


About Taking CriticismPamela email@example.com was originally published as a blog post at https://scatter.wordpress.com/2018/06/07/about-taking-criticism/AbstractThis essay is about constructive ways for responding to criticism about how your style as a person of power or privilege may be hurting others in your teaching or advising. Along the way it addresses the broader problems of taking criticism in general and of cultural differences in interaction styles. The punchline is about trying to be who you are (no personality transplants) in a way that respects both yourself and others and helps make your environment feel inclusive for more marginalized people. Sections discuss five issues: (1) Pay attention to issues of power and privilege. (2) Let people know you are open to criticism, including suggestions for classroom strategies. (3) Respect cultural and personal differences in interaction style and look for ways to communicate across these differences with attention to have this interacts with issues of power and privilege. (4) Learn general principles of taking criticism, including staying calm, listening for understanding, asking for time to think and reflect on critiques. (5) Pay attention to the problem of destructive criticism, including destructive relationships and bad classroom dynamics. The conclusion emphasizes that including formerly marginalized groups inevitably produces cultural conflict. Openness to criticism is a way forward for bridging differences in cultural and personal styles.


Graphene has been reported to show polarization-dependent optical absorption in the visible spectral range, that it shows more absorption for s-polarized light than p-polarized light. We study further on it and demonstrate that this unique property can be utilized to design a fiber optic sensor, which works in a similar way of surface plasmon resonance (SPR) fiber optic sensor. However, they are based on different mechanisms. Numerical simulation reveals that graphene layer of 5 nm is appropriate for the fiber optic sensor to achieve its best sensing performance, with a high sensitivity from 1700 to 6900 nm/RIU (refractive index unit).

Waste heat can be directly converted into electrical energy by performing the Olsen cycle on pyroelectric materials. The Olsen cycle consists of two isothermal and two isoelectric field processes in the electric displacement versus electric field diagram. This paper reports on the electrical energy generated by lanthanum-doped lead zirconate titanate (8/65/35 PLZT) subjected to the Olsen cycle. The material was alternately dipped into a cold and a hot silicone oil bath under specified electric fields. A maximum energy density of 888 J l−1/cycle was obtained with a 290 µm thick 8/65/35 PLZT sample for temperatures between 25 and 160 °C and electric fields cycled between 0.2 and 7.5 MV m−1. To the best of our knowledge, this is the largest pyroelectric energy density experimentally measured with multiple cycles. It corresponded to a power density of 15.8 W l−1. The electrical breakdown strength and therefore the energy and power densities of the material increased as the sample thickness was reduced from 720 to 290 µm. Furthermore, a physical model for estimating the energy harvested by ferroelectric relaxors was further validated against experimental data for a wide range of electric fields and temperatures.


Grenville age rocks are recognized in eastern North America from Newfoundland to Georgia and are part of a globe encircling belt. Whole rock Pb-U-Th isotope systematics permit recognition of distinct lead isotopic reservoirs that may reflect juxtaposition of different crustal blocks. Pb isotopic analyses of over 80 samples of basement rocks from PA to GA define at least two distinct groups. Group 1 includes rocks from VA, Md, and Pa, while Group 2 includes rocks from GA and NC. Initial Pb isotopic compositions of the basement rocks of the Virginia Blue Ridge (of Group 1) are used as a reference for comparing all other isotopic ratios. These reference isotopic values are Pb-206/Pb-204: 16.63--18.64, Pb-207/Pb-204: 15.38--15.58, Pb-208/Pb-204: 33.52--39.51. The isotopic deviation in percent (Delta 207/204, Delta 208/204) show a remarkable separation of the basement massifs into separate U-Th-Pb provinces. For example, Delta 207/204 and Delta 208/204 values for other Group 1 rocks range from [minus]4.4 to 3.6 and [minus]30.9 to 11.1 respectively. Rocks of Group 2 have a higher percent deviation from the reference. For example, the Carvers Gap Gneiss of NC has a Delta 207/204 range of 4.63--13.25 and a Delta 208/204 range of 91.78--414.78. Limited published lead isotopic datamore » for other Grenville age basement massifs from Newfoundland to Texas have similarities and differences in terms of their time-integrated Th/U and U/Pb relative to the reference values presented here. The use of Pb isotopes to determine source region characteristics for crustal provinces has far reaching implications. Differences between juvenile crust and reworked older crust, leading to similarities or differences in reservoirs can be used as a method for determining the accretionary history of distinct terranes during the Grenville Orogeny.« less


The efficacy of marine protected areas (MPAs) may be reduced when climate change disrupts the ecosystems and human communities around which they are designed. The effects of ocean warming on MPA functioning have received attention but less is known about how multiple climatic stressors may influence MPAs efficacy. Using a novel dataset incorporating 8.8 million oceanographic observations, we assess exposure to potentially stressful temperatures, dissolved oxygen concentrations, and pH levels across the California MPA network. This dataset covers more than two-thirds of California's 124 MPAs and multiple biogeographic domains. However, spatial-temporal and methodological patchiness constrains the extent to which systematic evaluation of exposure is possible across the network. Across a set of nine well-monitored MPAs, the most frequently observed combination of stressful conditions was hypoxic conditions (<140 umol/kg) co-occurring with low pH (<7.75). Conversely, MPAs exposed most frequently to anomalously warm conditions were less likely to experience hypoxia and low pH, although exposure to hypoxia varied throughout the 2014–2016 marine heatwaves. Finally, we found that the spatial patterns of exposure to hypoxia and low pH across the MPA network remained stable across years. This multiple stressor analysis both confirms and challenges prior hypotheses regarding MPA efficacy under global environmental change.

Subjects and methods: A cross-sectional study was conducted to determine whether a spot urine protein/creatinine ratio (UPr/UCr) provides accurate quantitation of 24hour urinary protein excretion (24-h Prot) in outpatients with primary glomerulonephritis and different levels of renal function. Patients were classified into three groups according to creatinine clearance (ml/min) and into five categories according to morning UPr/UCr. Correlation between 24-h Prot and UPr/UCr was calculated according to the three levels of renal function. The Bland and Altman method was used to assess agreement between 24-h Prot and UPr/UCr. Limits of agreement were obtained calculating the mean difference between 24-h Prot and morning UPr/UCr ± 2SD. Sensitivity and specificity were determined for different renal function levels and UPr/UCr cut-off values. Results: High correlation coefficients (r=0.91, 0.95 and 0.98) were observed in patients with normal, reduced and severely reduced renal function. Differences and variability between 24-h Prot and UPr/UCr tended to increase with higher proteinuria levels, and this trend was observed for the three levels of renal function. The best UPr/UCr cut-off values to detect abnormal or nephrotic proteinuria were 0.3 and 2.6, respectively. Conclusions: Correlation and agreement between UPr/UCr and 24-h Prot is good for all renal function levels, but shows more marked differences as urinary protein excretion increases. Morning UPr/UCr has good sensitivity and specificity for diagnosis of 24-h Prot, even in patients with reduced renal function.


Tea polyphenol (TP) in the low-grade green tea could inhibit Ganoderma lucidum to grow, but the low concentration TP might induce Ganoderma lucidum to produce polyphenol oxidase (PPO). When PPO decomposed the polyphenol during fermentation process, the effect of the polyphenol on Ganoderma lucidum growth was reduced, extracellular metabolic products were accumulated, the ratio of polyphenol and amino acid was declined and the concentration of tea pigment was raised. Consequently, it was of great importance to study the metabolic control further. In this work, using orthogonal test, the effect of different compositions of fermentation medium on Ganoderma lucidum producing PPO in the low-grade green tea was evaluated and the best medium compositions were as follow: sucrose 2.5%, peptone0.25%, low-grade green tea2.5%, KH2PO40.2%. It was also found that the best fermention coditions were pH 5.0, 200 rmin-1, 30 , inoculum volume 10%, cultivating liquor 20%, cultivating time 7 d, and in these optimized conditions the enzyme activity might arrive at 95 UmL-1.


The RF power expander for extending the RF signal over a wide range of power with improved efficiency is the main expander (20) for extending the RF signal over the first range of power and having a power saturation level below the maximum of the wide range of power. ). A plurality of auxiliary expanders 21, 22, 23 are biased to continuously provide an extended output signal after the main expander 20 reaches saturation. It is connected in parallel with the main expander 20 with each of. The input signal is provided to the main expander 20 and the plurality of auxiliary expanders 21, 22, 23 via a signal separator 32 and the main expander 20 and the plurality of auxiliary expanders 21, 22,. The output for receiving the extended output signals from 23 includes a resistive load R / 2. The separated input signal is applied to the main expander 20 through a 90 degree transformer 30, and the output of the auxiliary expanders 21, 22, 23 is passed through the 90 degree transformers 24, 25, 26. Applied to the output rod 28. When operating prior to saturation, the main expander 20 transfers power to a load of 2R, the main expander 20 transfers current to a load that is half the current at full power and the expander is saturated do.


Casual readers of the Western press might be surprised to discover that in spite of the steady stream of negative reports about Russian political apathy and fatalism, the Russian environmental movement is alive and active. Environmental organizations working on issues from nuclear safety to local parks can be found in each of the Russian Federation's eighty-nine constituent regions. In the decade since the Soviet Union's collapse, these organizations have weathered a number of inauspicious social, economic, and political changes and have developed strategies to survive and continue their activism. Many Russian environmental organizations owe their ability to continue to operate, and indeed proliferate, to Western foreign assistance, primarily in the form of competitive grant programs designed to foster the development of civil society and democratization in Russia; at the same time, other small groups have developed survival strategies based on resources in their local communities. In this article I assess the role of Russian environmental organizations from the perspective of their contribution to the development of civil society in post-Soviet Russia. Drawing on the social scientific literature on civil society, I consider environmental groups' role as civic associations that serve as intermediaries between the state and society, transmitting ideas and information, influencing government policymaking, and encouraging citizen participation in the public sphere. In narrowly focusing on the intermediary role of the organizations, I refer only briefly to the substantive goals and achievements of Russian environmentalists in their efforts to limit environmental degradation, conserve ecosystems, and strengthen environmental policies. Although Russian environmentalists have faced a number of obstacles, they have developed the movement's organizational base and continue to articulate a greener vision of Russia's future. To clarify environmentalists' contribution to civil society development in Russia, I separate environmental groups into two broad categories: professionalized environmental organizations that emulate Western advocacy NGOs, and grassroots citizens' initiatives. (1) This distinction captures the difference between two classes of environmental groups that have been subject to different, albeit overlapping, opportunities and incentives, and that have formed different relationships with Russian state and societal actors. I will demonstrate that the differences between the two categories can be traced to two related factors: the groups' resource bases and their relations with Russian government institutions and officials. Foreign assistance donors and scholars most often have focused on professionalized organizations when assessing civil society development in Russia. (2) I argue that while professionalized environmental organizations bear a closer resemblance to Western advocacy NGOs, they are not very effective in an intermediary role. Environmental groups at the grassroots level are often overlooked because of their small size and scant resources, yet they may prove to be more sustainable and more effective at encouraging participation, generating social trust as the basis for future cooperation and participation, and fostering Russian civil society the long term. Professionalized environmental organizations are characterized by their reliance on external sources of funding, primarily foreign grants. Partly as a result of their reliance on foreign funds, however, professionalized organizations generally lack ties to their natural constituency--the Russian population--and therefore have a weak claim to representing the public. As relatively isolated elite organizations, they have had a low impact on public participation. While foreign funding provides the professionalized organizations the independence to challenge government policies on issues such as freedom of information, transparent policymaking, and government accountability, they also have been singled out as targets of government repression, a countermeasure made easier by their weak societal support. …


Introduction Fire disaster preparedness (FDP) comprises pre-fire disaster actions and activities taken to prepare and respond to fire disasters in the built environment. They are also sets of pre-incident actions taken in readiness to improve the capability to responding to a fire disaster and thus seeking to minimise the scale of the fire disaster (Ayonga, 2016; Nestory, 2017). FDP is an ongoing process of planning, organising, training, evaluating, equipping, exercising and improving methods and systems to sustain effective and efficient coordination, collaboration and enhancement of competence to respond to fire disasters. (Stikova, 2016; Agyekum, Ayarkwa and Opoku, 2017). Studies have stressed how vital FDP is to the built environment and equally to the society at large (Nouban and Yunusa, 2020). This is because, economically, socially and environmentally, prevention and preparedness are far better and cheaper than response and recovery operations (Westcott, Ronan, Bambrick and Taylor, 2017). Hence, the need for proactive rather than retroactive actions in order to avert disasters in the built environment.


Runoff from flood-irrigated perennial pastures generally contains higher phosphorus (P) and nitrogen (N) concentrations than the irrigation water applied to the pastures. We examined the sources of P and N that could contribute to these elevated nutrient concentrations in runoff. The first experiment compared P and N losses in runoff from pasture cut to different residual pasture masses. Flow-weighted P and N concentrations and loads were about 100% higher from pasture cut to 47 mm above ground than from pasture standing at 155 mm. These results indicated that severely defoliated pasture may be a significant source of nutrients when flood irrigated. In the second experiment, pastures were defoliated at a single grazing with different stocking intensities and the flow-weighted P and N concentrations in runoff were determined during 4 successive flood irrigation events. Nitrogen and P concentrations in runoff after the first irrigation following defoliation were higher at the highest stocking intensity. However, the effect of the grazing on nutrient concentrations in runoff declined in subsequent irrigation events. A regression model fitted to the P data indicated that there was a significant linear increase in P concentrations with stocking density and a significant non-linear decline in concentrations with successive irrigations. A similar relationship for TKN concentrations in runoff at each stocking density over the 4 irrigation events was not found. An inconsistency of the TKN concentrations of the supply water between irrigation events possibly helped to mask a similar relationship between N concentrations in runoff and stocking density over the 4 irrigation events. We postulate that both animal excreta and the pasture itself can contribute to elevated nutrient concentrations in flood-irrigation runoff.

Feed lectins are one of the etiological factors contributing to the occurrence of gastroenteritis in piglets. In this study, a comparative analysis of various methods for neutralizing lectins in the feeds of weaned piglets was carried out: heat treatment and the addition of lectin-specific carbohydrate glucosamine. The causative role of lectins in the development of gastroenteritis and their negative impact on animals was confirmed by general and biochemical blood tests. The paper presents the positive effect of neutralization of feed lectins on production indicators and the incidence of gastroenteritis. It has been established that the use of 0.1 g of glucosamine per 1 kg of feed is the optimal dose, which reduces the incidence of gastroenteritis by 8%, reduces the duration of the disease by an average of 0.5 days and animal mortality by 2%.


Hydrogen-hydrogen pairing is explored in the low hydrogen concentration metal hydride YHo.z, using extended Huckel tight-binding calculations. A comparison with Hz molecular complexes, where close H-H contacts occur, allows us to explain why through-space pairing must be ruled out in YHo.* An orbital explanation of the Switendick criterion is given. Compared to various possible occupation sites, the through-atom coupling observed in YHo.z might be favored because of Peierls distortion effects. This preference appears to be sensitive to the nature of the metallic host and the hydrogen concentration.


The article views the theoretical background for studying the universal concept and fundamental categories in the natural language. This problem is considered in the context of classical and modern linguistic traditions. The perspectives of the guestion under discussion are outlined.


79 post-tracheostomy patients were clinically ana-lyzed in our intensive care unit from May 1988 to August1991.32.9% of the patients developed secondary pul-monary infections which were more frequent in patientswith adult respiratory distress syndrome,craniocerebraland spinal injuries.The predominant pathogens culturedwere highly respiratory distress syndrome,craniocerebraland spinal injures.The predominant pathogens culturedwere highly resistant gram-negative bacilli.The patientswho received mechanical ventilations were more oftenpredisposed to pulmonary infections than those who didnot(P0.01).Proventive administration of antibioticsdid not appear to influence the incidence of pulmonary in-fection(P0.05).The effective antibiotics and preven-tive measures were disussed.


For near- and far-field microwave imaging purposes, array of circular resonant slots can be utilized to sample the electric field at a given reference plane. In general, the sensitivity of such an array is impaired by the existing mutual coupling between the radiating elements or in this case circular slots. The mutual coupling problem imposes a design tradeoff between the resolution of the array and the overall system sensitivity and dynamic range. In this paper, the mutual coupling between circular resonant slots in conducting ground plane is investigated both numerically and experimentally. In particular, the mutual coupling in the E- and H-plane configurations of two identical slots is studied.


Electrical and electronic equipment installed on military platforms must have very low electromagnetic emission and good immunity for the whole operational frequency range. Reverberation Chambers (RC) are tools for sensitive emission measurements and immunity tests against strong electromagnetic fields, at a lower cost than other techniques. Method of RC should be suitable for testing Military's electronic devices such as radio or radar system. However, RCs must be large for tests at low frequencies; for example, at 80 MHz are conventional RC must have dimensions up to 7 m by 15 m by 8 m. For military concern, the lowest operation frequency can be as low as 2 MHz (underwater communication can be lower). Conventional RCs can only be used above a certain frequency, the lowest usable frequency (LUF), as they require a minimum mode density (number of modes per frequency interval) in order for the stirrer to perform effectively and alter field distributions. Technique of MIMO RC [1, 2] can make RCs usable down to much lower frequencies; it can mean the dimensions of the chamber can be up to 6 times smaller. However, the composite Q-factor of RCs can be rather low at low frequencies, and this affects the sensitivity, and ultimately usability of an RC. This paper studies the possibility to increase composite Q-factor when RC is used at lower frequencies than conventional method.


The eternal domination problem requires a graph be protected against an infinitely long sequence of attacks at vertices, by guards located at vertices, with the requirement that the configuration of guards induces a dominating set at all times. An attack is defended by sending a guard from a neighboring vertex to the attacked vertex. We allow all guards to move to neighboring vertices in response to an attack, but allow the attacked vertex to choose which neighboring guard moves to the attacked vertex. This is the all-guards move version of the "foolproof" eternal domination problem that has been previously studied. We present some results and conjectures on this problem.


"The Chinese 'word,' or ideogram, for red is based on things everyone KNOWS." (Pound 1960:22). Concrete poetry, going beyond the application of ideogrammic process as practiced by Pound, introduces space into the ideogram as a substantive element of poetic structure. In that way a new rhythmic, spatial-temporal reality is created. Traditional linear rhythm is destroyed. If we were to put this in Joycean terms (see Part I of Ulysses), we would say that concrete poetry results from the interaction of the verbal, from the ineluctable modality of the visible and the ineluctable modality of the audible, in a very short space of time through very short times of space. Joyce, like Pound, does not use the blank space of the page as an element of composition. He achieves in each of his famous metaphorwords a small verbivocovisual ideogram, to use his own terminology: silvamoonlake.1 This example also illustrates that "panaroma of all flores of speech," which Joyce began in Ulysses, and realized completely in his work of maximum complexity, Finnegans Wake. With reference to spatial achievements, one must cite above all the last, impressive work of Mallarme, Un Coup de D~s (1897). This is the first poetic work consciously and structurally organized according to space-


The end of the Pleistocene (~75-15 ka) is a key period for the prehistory of the Nile Valley. The climatic fluctuations documented during this period have led human populations from the Middle and Late Palaeolithic to adapt to a changing Nile. In particular, the global shift to more arid conditions regionally translated into the expansion of the Sahara, the lowering of sea levels and the desiccation of some major eastern African lakes. These climatically-induced environmental changes influenced the behaviour of the Nile – although how exactly is still debated – and its role as an ecological refugium for human populations living in its vicinity. Genetic and fossil evidence highlight a strong population substructure in Africa during this period, suggesting the alternation of phases of major dispersals of modern humans within the continent, as well as out-of and back-into Africa, with phases of relative isolation of populations, which might be linked to the creation of environmental refugia during the climatic fluctuations of this period. Understanding to what extent the technological variability observed in north-eastern Africa between 75,000 and 15,000 years ago is linked to environmental changes and/or possible contacts between different human populations is critical in this context. The best-preserved evidence for past human behavior are archaeological assemblages, most often lithic assemblages. However, the use of different terminologies, whether they refer to cultural or techno-typological entities, hampers any systematic comparison between the Nile Valley on one hand and neighbouring regions on the other hand. An outcome of this practice is the artificial 'isolation' of the north-eastern African record from its neighbouring regions. This monograph groups together chapters presenting updated reviews and new data on regional archaeological, palaeoenvironmental, palaeoanthropological and geological records from north-eastern Africa, North Africa, the Levant and eastern Africa for the period ranging from 75,000 to 15,000 years ago. While north-eastern Africa, and the Nile Valley in particular, is generally considered as one of the main possible routes of migrations out of Africa, few recent studies allow the data from this region to be viewed from a macro-regional perspective. This book allows the exploration of topical issues, such as modern humans' capacity for adaptation, particularly in the context of climate change, as well as population interactions and human dispersals in the past, taking a multidisciplinary approach.


Two unusual patients with erythema elevatum diutinum (EED) are reported. The first presented with large skin‐coloured nodules on the feet, whilst the second patient had smaller, purpuric and ulcerated nodules on the hand which contained calcium pyrophosphate crystals. This patient also had polycythaemia rubra vera and an IgA gammopathy. The wide clinical spectrum of EED is reviewed.


Plots were direct seeded on 17 Feb., in Rockdale soil. Each plot was a single row on 6-ft centers, 15-ft long. Normal cultural practices were followed using white on black plastic mulch and overhead irrigation. There were four replications per treatment in a randomized block design. Treatments were applied weekly from 25 Mar. to 20 May, for a total of nine applications except DPX-H524-16 which was only applied the last 7 weeks. Treatments were applied with a tractor mounted sprayer with five nozzles per row, 250 lb/in2, and in 100 gal of water per acre. on 3 May, the total numbers of leafmines and live larvae per leaf (third fully-expanded leaf from terminal were counted from 10 randomly selected plants per plot. On 10 May, the total numbers of pinworm mines per leaf (fourth fully expanded leaf from terminal) were counted from 10 randomly selected plants per plot. Adult southern green stink bug counts were taken on 10 May by shaking 3 row-ft of plants over a white cloth and counting the stink bugs on the cloth. Mature green to ripe fruit were harvested on 24 May. The percentage of fruit damaged by southern green stink bug was determined by examining 25 randomly selected fruit per plot. The leafminer and pinworm populations were normal, but the southern green stink bug population was unusually high.


El Niño typically peaks in boreal winter, and the associated equatorial Pacific sea surface temperature (SST) signal dissipates before subsequent summer. Its impact, however, outlasts until boreal summer in the Indo-western Pacific, featuring basin-wide Indian Ocean warming and tropical Northwestern Pacific cooling accompanied by the Pacific-Japan (PJ) teleconnection pattern with an surface anomalous anticyclone (AAC) extending from the Philippine Sea to the northern Indian Ocean. Two formation mechanisms have been proposed for these climate anomalies in post-El Niño-Southern Oscillation (ENSO) summer. One hypothesis invokes the wind-evaporation-SST (WES) feedback in the tropical Northwestern Pacific, while the other points to inter-basin feedback between the Indian Ocean and tropical Northwestern Pacific. Based on a coupled model experiment, we propose an ocean-atmosphere coupled mode that synthesizes the two mechanisms. This Indo-western Pacific Ocean capacitor (IPOC) mode evolves seasonally from spring to summer under seasonal migration of background state. In spring, the WES feedback is operative in association with the tropical Northwestern Pacific cooling, while in summer the Indian Ocean warming and the inter-basin interaction maintains the AAC. While the IPOC mode is independent of ENSO in mechanism, ENSO can drive this mode in its decay phase. This excitation, however, has undergone substantial interdecadal modulations, depending on ENSO amplitude and persistence of Indian Ocean warming. The ENSO-IPOC correlation is high after the mid-1970s and at the beginning of the 20th century, but low in between. Air-sea


Using a 2.5-dimensional ideal MHD model in Cartesian coordinates, weinvestigate the equilibrium properties of coronal magnetic flux ropes in backgroundmagnetic fields that are completely closed. The background fields are produced by adipole, a quadrupole, and an octapole, respectively, located below the photosphereat the same depth. A magnetic flux rope is then launched from below the photo-sphere, and its magnetic properties, i.e., the annular magnetic flux φp and the axialmagnetic flux φz, are controlled by a single emergence parameter. The whole sys-tem eventually evolves into equilibrium, and the resultant flux rope is characterizedby three geometrical parameters: the height of the rope axis, the half-width of therope, and the length of the vertical current sheet below the rope. It is found thatthe geometrical parameters increase monotonically and continuously with increasingφ p and φz: no catastrophe occurs. Moreover, there exists a steep segment in theprofiles of the geometrical parameters versus either φp or φz, and the faster thebackground field decays with height, the larger both the gradient and the growthamplitude within the steep segment will be.

Abstract Electrokinetic potential (zeta potential) for selected 21 polymer foils was studied. The results on zeta potential are supplemented with contact angle measurements (goniometry) and with the results on surface roughness measured by atomic force microscopy (AFM). Zeta potential was determined using two approaches: streaming current and streaming potential at pH=6.0-6.2. Two electrolyte solutions with KCl (concentrations 0.001 and 0.005 mol/dm3) and KNO3 (0.001 mol/dm3) were used in the experiments. Zeta potential was shown to depend on surface chemistry, polarity, roughness and morphology of the polymer foils.


Objective: Cytokeratins are epithelium-specific intermediate filaments. Their altered expression is evident in various benign, hyperplastic and neoplastic lesions. This review provides an in-depth description of cytokeratin expression patterns in odontogenesis; normal development, hyperplastic/benign and malignant lesions or conditions. Materials and methods: Cytokeratin expression can be studied by numerous techniques like immunohistochemistry, immunofluorescence and in situ hybridization. Results: The variable expressivity of cytokeratins is a subject of continuous deliberation and ongoing research. This paper gives an in-depth analysis of cytokeratin expression in a variety of epithelial tissues. Conclusion: Cytokeratins are universal indicators of epithelium specificity. An alteration of expression can be well understood by means of a proper understanding of their normal presence.


Presentation of Case A 23-year-old man with asthma was admitted to the hospital because of an increased cough with pulmonary infiltrates. There was a history of mild asthma since childhood, which was managed occasionally with short courses of prednisone. More recently, the patient required medication for asthma approximately once a year for exacerbations that were provoked by upper respiratory tract infections or by swimming and that were treated with a corticosteroid inhaler. He had never required admission to a hospital because of wheezing. He had a chronic morning cough productive of scanty clear secretions. The patient was well otherwise until . . .


The reactions of S(IV) with Fe(III) in the presence of tetraethylenepentamine(T) have been investigated at pH = + 3.6-4.2 Fe(lII) is bound by the amine in a tridentate fashion (Fe(TH )5 +) with the two terminal primary amino groups remaining in the protonated form. The species Fe(1H )5 + under~oes sulp~te s~bs~tution to yield Fe(TH2XS03)3+. The rate and activation parameters fo/the formanon ~d. dissociation of the sulp~to complex are reported. Reduction of Fe(lII) by the coordinated sulphite IS slow. The redox reactton reveals the existence of two isomers of Fe(TH XSO )3+ in which ~O~is bonded trans-or cis to the coordinated H20 (axial or equatorial). From the 2 reactivity trend it IS presumed that the coordinated sulphite in the trans isomer reduces Fe(III) centre faster (by a factor of 10) than the same in the cis isomer. The product distribution experiments show that SOdime rises to Sp~besides being oxidised to SO~by Fe(III). 3


When electrolysis is performed using deuterium and a palladium cathode, more heat can be generated than can be explained by chemical processes, implying that deuterons are fusing but without the typical products of hot fusion (a phenomenon called LowEnergy Nuclear Reactions, LENR, or cold fusion). Fusion between deuterons usually requires temperatures of 100 MK to overcome the repulsive Coulomb forces. Here it is shown that a theory called quantised inertia predicts that in cracks in the metal with diameters less than 28 nm, the temperature is 27,000 K and mutual sheltering by the deuterons can produce an attractive radiation recoil force strong enough to push them together through their Coulomb barriers. This offers a potential explanation for cold fusion or LENR.

To solve the continuous and compact wavelet neural network(WNN)'s slow convergence speed problem,the Levenberg-Marquardt(LM) algorithm is proposed to improve the WNN,and in order to overcome the LM-WNN's shortcomings that it has too fast convergence speed,which make it easily trapped in local minimum points and platform,simulated annealing(SA)algorithm is used to optimize the parameters of the wavelet neural network,which results a group of approximate solution.The approximate solution is put as the initial value of weights and threshold matrix of the LM-WNN,to ensure that the LM-WNN converge to the global minimum point.Apply the SA-LM-WNN in analog circuit fault diagnosis problem,simulation results show that the algorithm can quickly converge to the global minimum,and the simulation effect is good.


Stochastic computing (SC), an unconventional computing paradigm that operates on stochastic bit streams, gains more and more attention recently because of the low area and power consumption of its computing core. SC relies on stochastic number generators (SNGs) to generate input stochastic bit streams. An SNG is composed of a random number source (RNS) and a comparator. However, conventional SNGs, which use linear feedback shift register (LFSR) as the RNS, consume much more area and power than the SC core, offsetting the small area and the low power advantages of the SC core. To mitigate this issue, some emerging devices, such as memristor and spintronic devices, were proposed to build SNGs. However, due to the large process variation in fabricating these devices, these SNGs are unreliable: their output probabilities could have a large error than the desired values. In this paper, we propose a general method to design reliable SNGs that use emerging device-based RNS's. Experimental results showed that our design is effective in improving the reliability. Keywords—stochastic computing; novel nanoscale devices; stochastic number generator (SNG)


Plant disease resistance is one of the most desirable traits for agricultural production, especially in the present time of fear over food production and crop security. Disease plays an important role in crop production and quality of products. The one key factor of food security and production is plant disease resistance. Several resistance gene(s) are reported from the same host range to overcome against disease resistance. These resistance (R) genes are not durable in many cases because of rapid changes in the pathogen population to overcome the resistance that they confer. For diagnosing such type of situation, continuous search of durable resistance sources from across the genera/species are desirable. Second type of resistance that is nonhost resistance has been described as inaccessibility. Nonhost resistance is regarded as a robust protection against pathogenic microorganisms because of its durability. The mechanisms of nonhost resistance could also be exploited to improve the resistance in a range of crop plants. Recently several components of nonhost resistance have been identified but such resistance is one of the least understood phenomenons in the area of plant microbe interaction. Molecular mechanism of nonhost resistance is not fully understood. Though, nonhost resistance will help biologist to engineer the plants for more durable resistance against important plant diseases. Therefore, non-host resistance seems to be one avenue under consideration for significant improvement of agriculture production in future.


1 Abstract: This paper examines whether the mandatory adoption of IFRS/IAS in the European Union is beneficial in terms of the information content of earnings. The informational relevance of earnings was reflected by the level of information asym- metry measured by the cost of capital and the financial analysts' forecasts. So, the article purpose is to study the impact of IFRS adoption on the cost of capital and on the financial analysts' forecasts. Using an unbalanced panel data of firm—year observations spanning from 2002 to 2012, we hypothesize and empirically find the following. First, IFRS adoption represents a key determinant of information asymme- try reduction, as it contributes significantly to the decrease in the capital cost for the post-IFRS period. Second, the adoption of these international standards has signifi- cantly contributed to the improvement of financial analysts' forecasts reflected by an enhancement of the forecasts properties, a decrease in dispersion and error. The results contribute to the literature dealing with the additional informational content stemming from IFRS mandatory adoption. The originality of this study consists pri- marily in the use of a long analysis period which eliminates any bias relating to the period of learning and understanding of IFRS and any bias related to the financial crisis started in 2007 and secondly in the use of two measurements of information asymmetry which makes the results obtained more robust.


Univariate methods for diagnosing nutritional status such as the sufficiency range and the critical level for garlic crops are very susceptible to the effects of dilution and accumulation of nutrients. Therefore, this study aimed to establish bivariate and multivariate norms for this crop using the Diagnosis and Recommendation Integrated System (DRIS) and Nutritional Composition Diagnosis (CND), respectively. The criteria used were nutritional status and the sufficiency range, and then the diagnoses were compared. The study was performed in the region of Alto Paranaiba, MG, Brazil, during the crop seasons 2012 and 2013. Samples comprised 99 commercial fields of garlic, cultivated with the cultivar "Ito" and mostly established in Latossolo Vermelho-Amarelo Distrofico (Oxisol). Copper and K were the nutrients with the highest number of fields diagnosed as limiting by lack (LF) and limiting by excess (LE), respectively. The DRIS method presented greater tendency to diagnose LF, while the CND tended towards LE. The sufficiency range of both methods presented narrow ranges in relation to those suggested by the literature. Moreover, all ranges produced by the CND method provided narrower ranges than the DRIS method. The CND method showed better performance than DRIS in distinguishing crop yield covered by different diagnoses. Turning to the criterion of evaluation, the study found that nutritional status gave a better performance than sufficiency range in terms of distinguishing diagnoses regarding yield.

In AML the translocation t(12;13)(p13;q12) results in the ectopic expression of the homeobox gene Cdx2 and the expression of the ETV6-CDX2 fusion. We have recently shown that myeloid leukemogenesis is induced by the ectopic expression of the proto-oncogene Cdx2 and not by the ETV6-CDX2 fusion gene in a murine model of t(12;13) AML. To characterize the contribution of different Cdx2 motifs to the transforming capacity of the gene we generated different mutants, inactivating the DNA binding homeodomain (N51S-Cdx2), or the PBX1-interacting motif (W167A-Cdx2), or deleting the N-terminal portion of Cdx2 (N-Cdx2). Expression of Cdx2 and the different mutants were induced in primary murine bone marrow cells by retroviral gene transfer, using an MSCV based retroviral construct with an IRES-YFP cassette. Expression of Cdx2 and the W167A-Cdx2 mutant significantly increased primary colony formation (3-fold) (n=3;p In vivo all mice transplanted with cells expressing Cdx2 or the W167A-Cdx2 mutant developed transplantable AML. However, in Cdx2 leukemic mice > 90% of the cells co-expressed Gr-1 + and Mac1 + , whereas in W167A mice 40% of the leukemic population were Gr-1 + only. The N51S mutant induced a distinct leukemia phenotype with 90 % Gr-1 + /c-Kit + . We extended structure-function analyses, inactivating the phosphorylation site (S60) in the Cdx2 transactivation domain, previously shown to be regulated by the MAPK family. We confirmed that oncogenic Cdx2 is phophorylated at the N-terminal in primary BM cells by Western blotting using a P-Cdx2-S60 specific antibody. S60 position mutation slightly reduced the hematopoietic activity of wild-type Cdx2 . Incubation with the MEK1 inhibitor PD98059 inhibited phosphorylation, decreased the frequency of CFU-S 8fold (n=7; p Cdx2 transfected blasts in vitro . In contrast, the p38 inhibitor SB2059 did not prevent phosphorylation and was unable to antagonize Cdx2 induced transformation. These data demonstrate that the transforming activity of Cdx2 and the phenotype of Cdx2 induced leukemias is depending on the functional integrity of distinct Cdx2 domains. Furthermore, our data link the oncogenic potential of Cdx2 directly to the MAPK signaling, opening the possibility to counteract Cdx2 associated leukemogenesis by kinase inhibitors.

This paper explores how upper secondary school (middle high school) students experience information literacy through resource-based school projects. It aims to understand whether these students have developed improved information literacy competencies after being exposed to various projects during their lower secondary grades. It also examines how, or in which direction of the "Three Directions Model" the students experience information literacy in their project journey. The research participants comprise of a group of seven students from a selected school in Shah Alam, Selangor. The research employs focus group interview data collection technique with the students. The findings show that the students in general have progressed in knowledge and various learning competencies as a result of repeated project work experiences. However, their mastery of fine information literacy skills was still low as information literacy models and literatures were not embedded in their project work instructions. It is recommended that information literacy models be clearly incorporated into project work instructions to assist the students to develop fine and detail information literacy skills. The findings are hoped to provide baseline information on information literacy development in learning contexts where information awareness is still low.


The hypothesis has been set down that at pressures ianging from 0.4 x 1 0 1 ~ to at least 3-6 x I O ~ * dynes/cm.8 (the latter being the pressure at the Earth's centre) the compressibility K-' of a substance at temperatures of the order of those in the Earth's deep interior is essentially independent of its chemical composition. A simple form of the hypothesis to the effect that K and dk/dp (where p denotes pressure) change continuously and smoothly throughout the Earth below a depth of 1000 km. has been discussed in relation to seismic data. The hypothesis entails an abnormally large density gradient in the lowest zoo km. of the Earth's mantle, and in the Earth's inner core, and that these two regions are not chemically homogeneous. It entails that the density near the Earth's centre lies between about 16 g./cm.8 and 20 g./cm.8 (apart from a possible accumulation of even denser material very close to the centre). The hypothesis in its simplest form would require the Earth's density to be a little higher in the region above the 1000-km. level than the figures given in a previous model. The hypothesis would entail that the inner core is solid, capable of transmitting S waves at a speed not less than about 4.9 km./sec. and probably less than 6.0 km./sec.
