Eco-economy is an assumption which is beneficial to earth and it is uphold the environment forever.It has been a new tide for many countries to carry out sustainable development.Based on the in-depth analysis on double challenges of eco-environmental vulnerability and poverty against the development of Ningxia in the new decades,the author put forwards the unconventional sustainable development strategy: "eco-economic development strategy",under which Ningxia could break the vicious circle of eco-environmental vulnerability and poverty,and achieving its sustainable development goal.The author especially discusses the connotation and routes of the eco-economic development strategy and gives some countermeasures and policy suggestions to promote the sustainable development in Ningxia.


Legal regulation status when rendering medical aid to HIV-infected patients has been analyzed. In this field, two main spheres of legal regulation are to be pointed out: the organization of medical follow-up and treatment of HIV-infected patients and special measures for providing HIV-infected citizens with medical aid. Lately, a number of new documents regulating the organization of specialized medical aid to HIV-infected patients has been accepted, the international approach to medical and social support to these patients rendered by a multidisciplinary team of specialists has been introduced into practice. Besides, in the nearest future, the legal regulation in this field of medical activity will need further improvement. The implementation of the Law of the Republic of Belarus «On preventing the spread of diseases threatening the health of the population, human immunodeficiency virus» will result in some new problems. More detailed regulation of interdisciplinary interaction when organizing multidisciplinary team activity and palliative aid to AIDS patients is needed as well.


We introduce the notion of a near-inverse of a non-decreasing sequence of positive integers; near-inverses are intended to assume the role of inverses in cases when the latter cannot exist. We prove that the near-inverse of such a sequence is unique; moreover, the relation of being near-inverses of each other is symmetric, i.e. if sequence g is the near-inverse of sequence f, then f is the near-inverse of g. There is a connection, by approximations, between near-inverses of sequences and inverses of continuous strictly increasing real-valued functions which can be exploited to derive simple expressions for near-inverses.


A foreland-basin sequence resulting from accretion of a terrane to a continental passive margin ideally should be unconformity bounded, with a shallowing-upward pattern, like the classic Flysch to Molasse sequence of Alpine foreland basins. The basal unconformity is cut as the peripheral bulge associated with lithospheric flexure migrates cratonward ahead of the basin and the advancing overthrusts. The shallowing occurs because sediment supply at first is low – early stages of accretion near the continental slope generate little or no topography above sea level; later stages result in significant tectonic uplift, and much sediment is shed into the foreland, filling the basin. The upper unconformity is cut as lithospheric bending stresses are relaxed following overthrusting, and reduction of the flexural load on the lithosphere through erosion and (or) tectonic denudation of the overthrusts causes regional uplift or basin "rebound". Actual sequences show differences from this idealized version in that (i) ...


Simple Summary Studies on the evolution of Neotropical primates are currently based on molecular cytogenetics. Recent technological advancements have provided new capabilities and opportunities to explore novel mechanisms of evolutionary dynamics. We analyzed the genomic instability and variability in two species of Ateles by characterizing the spontaneous frequencies of sister chromatid exchange (SCE) along chromosomes (genomic) and specifically within telomeres. Our analyses support the hypothesis that regions of Ateles chromosomes susceptible to recombination events represent fragile sites and evolutionary hot spots. Therefore, we propose SCE analyses as a valuable indicator of genome instability in non-human primates. Abstract There are extensive studies on chromosome morphology and karyotype diversity in primates, yet we still lack insight into genomic instability as a key factor underlying the enormous interspecies chromosomal variability and its potential contribution to evolutionary dynamics. In this sense, the assessment of spontaneous sister chromatid exchange (SCE) frequencies represents a powerful tool for evaluating genome stability. Here, we employed G-banding, fluorescence plus Giemsa (FPG), and chromosome orientation fluorescence in situ hybridization (CO-FISH) methodologies to characterize both chromosome-specific frequencies of spontaneously occurring SCE throughout the genome (G-SCE) and telomere-specific SCE (T-SCE). We analyzed primary fibroblast cultures from two male species of Ateles living in captivity: Ateles paniscus (APA) and Ateles chamek (ACH). High frequencies of G-SCEs were observed in both species. Interestingly, G-SCEs clustered on evolutionary relevant chromosome pairs: ACH chromosomes 1, 2, 3, 4, and 7, and APA chromosomes 1, 2, 3, 4/12, 7, and 10. Furthermore, a statistically significant difference between the observed and expected G-SCE frequencies, not correlated with chromosome size, was also detected. CO-FISH analyses revealed the presence of telomere-specific recombination events in both species, which included T-SCE, as well as interstitial telomere signals and telomere duplications, with APA chromosomes displaying higher frequencies, compared to ACH. Our analyses support the hypothesis that regions of Ateles chromosomes susceptible to recombination events are fragile sites and evolutionary hot spots. Thus, we propose SCE analyses as a valuable indicator of genome instability in non-human primates.


As software grows in size continuously, traditional monolithic architecture is difficult to upgrade and update. As a more flexible architecture, microservices consist of smaller pieces or services that are loosely coupled and can be deployed independently. More and more IT companies are adopting microservices architecture. However, migrating to microservices is still a big challenge due to the lack of a more systematic methodology on microservices identification. Most existing studies on microservices identification are mainly based on refactoring the system module rather than considering the actual functional requirements. Therefore, we propose a microservices identification approach based on the problem frames to address this challenge, which considers real-world requirements. It relies on the merging process with the problem diagram, where the problem domain is processed, and the causal chain is obtained by searching the problem diagram. Subsequently, we calculate the correlation degree of the domains in the problem diagram. Then, based on the calculated correlation, we implement a clustering algorithm for the problem domains and get the categorization result of the problem domains which is the initial microservice candidate. The developers can consider each category of the problem domain as a microservice by converting the problem domains into the microservices. Finally, a case study verifies the validity of our proposed approach.


This paper discussed about design, fabrication and characterization of pH transducer on printed circuit board (PCB). The main objective is to explore the possibility of pH transducer by using interdigital capacitor (IDC) on PCB and to study the performance of interdigital capacitor on PCB. The transducer can be used to sense the pH value for a solution. The term interdigital refers to pattern of fingers that is resembled by the shape and relative position of the electrodes. This transducer was fabricated by using PCB in order to prepared a lower cost pH transducer compared to the commercialize pH transducer. In addition, the result produces the capacitance changes over the time is 0.0189 µF/s. Moreover, the percentage of drift test is about 39.6% and the hysteresis is about 0.086µF and 0.895 µF. The results show that a good correlation coefficient was observed in sensitivity test. The correlation coefficient for sensitivity test is about 0.65. As long as the value of correlation coefficient is above 0.5 the transducer is good.


We often speak about learner autonomy in higher education as something that is first and foremost what we want students to attain. This is often translated into the notion of independent or self-directed learning. The step-change from school education to the first year of higher education is often considered as a transition point in this direction. However, the educational process is not exclusively an independent solitary activity, but rather involves learning with and from others, or learning communities as they are now sometimes called. Knowledge and skills are developed with respect to public criteria in ways through which understanding can be displayed and assessed. It is also the case that we want students to develop themselves vis-à-vis what they learn, to move beyond considering education as a process of straightforward knowledge acquisition to one of change and growth. This may be considered in terms of professional socialisation, personal development or some combination of both through the development of graduate attributes. However, often the goal of the first year in Scottish higher education is to provide students with a disciplinary grounding that can enable them to then later move towards greater independent learning. For all the recent focus on personalisation of learning, much of the curriculum and pedagogy in the first year is perhaps still devoted to knowledge acquisition. The aim of this paper is to consider the challenges in building learner autonomy through the first-year curriculum such that students can begin to relate their personal relationship with knowledge to that of wider public criteria.


This paper describes design procedure of a centrifugal blower using the program of Excel. Basic input variables for the impeller design are flow rates, rotating frequency of an impeller and pressure rise. Euler equation is introduced to determine design variables including a velocity triangle. The size of impeller and the number of impeller blade are determined by Cordier's correlation and slip factor of Stodola, respectively. In the design of a volute casing, a spiral equation having a exponential term is applied. Design program of a centrifugal blower using Excel has been constructed and tested for understanding the effect of design variables on the geometry of a blower.


First to modernize among the non-Western countries, Japan undertook the unprecedented task of establishing Western-style universities on an entirely different historical background and of promoting in them scientific research. In the Heian period, a system of training imperial officials created in imitation of a Chinese example, included the fields of mathematics, astronomy and medicine. The Meiji government, with the political changes of 1881, adopted a German form of nationalism rather than democracy, and prepared for the coming establishment of the constitution. The history of Japan as a modern country is influenced by the Russo-Japanese War, the Sino-Japanese War and the First World War, which took place within intervals of ten years. The establishment of Kyoto Imperial University was expressly intended to oppose the monopolistic position of the Imperial University in Tokyo. Thus, a hierarchy is often apt to be established among the university researchers.Keywords: Heian period; Kyoto Imperial University; Meiji government; Russo-Japanese War; Sino-Japanese War


The study explores the use of the marketing strategy concept, guided by the idea of the original definition of strategy. This definition limits the number of organizational levels where the concept might apply. This restriction affects the application area of the label "strategic" in the marketing function. The study is based on logical reasoning associated with the original content of strategy and with the state of facts in the real world of business. The reasoning used in the study is similar to the reduction at absurdum approach, used in mathematics. Key-words: strategy, marketing strategy, strategic marketing 1. Strategy as a label for something important "Strategy" and "strategic" are words that enjoy an intense use during the last years. They are used in the most surprising contexts, starting with scientific claims of a particular field and ending with the usual ones associated with current activities marked by banality. In many standard cases the use of the term could be quite excessive. The benign consequence of this is the creation of vague formulations associated to the main concept. But more serious is the possibility to create some confusion related to the basic concepts of strategy that refer to or used in any form the label "strategic." The attribute "strategic" showed an expansion in the common language so spectacular that it is natural concern that a misuse of the label occur. This feeling is accentuated by the fact that the label "strategic" is only used as a beacon for what is intended to be perceived as important. Rumelt (2011) says that the use of this label became a verbal tic. There is an avalanche of strategic "stuff", management, resources, projects, decisions, and many otherswhich might create the idea that the lack of such labeling creates frustration to the ones involved in these "stuff", thus getting this particular attribute becomes an implicit objective of their work. Does the label fit in all cases? 1 Transilvania University of Braşov, email@example.com

We deal with a singular nonlocal fractional differential equation with Riemann-Stieltjes integral conditions. The exact iterative solution is established under the iterative technique. The iterative sequences have been proved to converge uniformly to the exact solution, and estimation of the approximation error and the convergence rate have been derived. An example is also given to demonstrate the results.


The effects of ascorbate (vitamin C) and azidothymidine (AZT) were examined on HIV expression in permanently infected and reporter cell lines. In T-lymphocytic HXB cells, constitutively producing moderate to high levels of virus, ascorbate suppressed HIV production and reduced the yield of infectious virus released into the culture supernatant. AZT, which has been reported to block de novo infection of freshly infected cells, did not inhibit constitutive virus production in HXB cells. In latently infected ACH-2 T-cells, producing low basal level of virus, exposure to phorbol ester (PMA) caused about 10-fold increase in virus production. Pre-treatment of ACH-2 cells with ascorbate followed by PMA stimulation resulted in a dose-dependent reduction in the extracellular level of HIV reverse transcriptase activity. AZT treatment did not suppress HIV activation in PMA-stimulated ACH-2 cells. In mixed cultures of uninfected HLCD4-CAT and infected HL2/3 cells, ascorbate did not affect virus-induced (taX-mediated)...

The aim of the study was to examine the effectiveness of the Discovery Learning Module on Geometry (D-Geometry Module) in improving reasoning skills, communication, and self-confidence in mathematics among secondary school students. The research design was a quasi-experimental with a non-equivalent control group with pre-test and post-test design, where 128 students were grouped according to gender and the group of the intervention as well as a traditional group. Mathematical reasoning skills, communication, and self-confidence instruments were administered towards the students involved. Two-way MANOVA analysis showed that there was a main effect of the grouping. The finding showed that the integration of learning theories and discovery learning in Geometry could improve students' reasoning, mathematical communication, and self-confidence. Students' engagement is more dominant through the Discovery Learning Module rather than traditional learning. Therefore, the D-Geometry module should be used as a teaching resource for teachers, students, and curriculum-2013 (K-13) to facilitate classroom instruction. https://doi.org/10.26803/ijlter.19.3.1 2

AIM
Smoking is harmful to human health. However, the relationship between smoking and blood pressure (BP) has not been consistent. This study aimed to analyse nurses' smoking behaviours and their relationship with BP.

METHODS
This cross-sectional study recruited 128 009 nurses in 11 cities in China. They were surveyed with questionnaires including BP measurements. The main contents of the questionnaire included smoking status and other factors that might be associated with hypertension. Multiple linear regression analyses and binary logistic regression analyses were used to analyse the data.

RESULTS
The results showed there was a significant difference in the smoking rate among nurses with different characteristics (P < 0.05). For both male and female nurses, smoking was associated with increased diastolic BP and mean arterial pressure, but only with increased systolic BP of male nurses. The prevalence of hypertension among male and female nurses was not related to smoking.

CONCLUSION
Despite a relatively low overall smoking rate, rates among some groups are high. Different cities, hospitals, and departments can combine local data and conditions to formulate targeted tobacco control measures to improve nurses' physical and mental health.

A simple stability indicating HPLC method was developed and validated for determination of moxifloxacin hydrochloride in the presence of its induced degradation products. The drug was subjected to stress stability studies including acidic, alkaline and oxidative stress conditions, and the stressed samples were analyzed by the proposed method. The developed method utilized Symmetry C18 column (250 × 4.6 mm, 5 im) in an isocratic separation mode. The mobile phase consisted of methanol: 0.2 % triethylamine (pH 2.5 with orthophosphoric acid), (35: 65, v/v) at a flow rate 1.5 mL/min with UV-detection at 290 nm. The proposedmethod was validated according to the International Conference on Harmonization (ICH) guidelines. The method was applied for determination of moxifloxacin hydrochloride in pure powder and in its pharmaceutical formulations.


Objective: Postoperative radioiodine remnant ablation (RRA) represents an adjunctive therapeutic modality in patients with differentiated thyroid cancer (DTC). The impact of late versus early RRA on the outcome of DTC is currently unclear. The aim of the study was to evaluate the outcome of patients with DTC according to RRA timing Design: Retrospective study Patients: 107 TNM stage 1 DTC patients were divided into two groups. In group A (n=50) RRA was administered in less than 4.7 months (median 3.0 (range 0.8-4.7), while in group B (n=57) in more than 4.7 months (median 6 (4.8-30.3) after thyroidectomy. Remission was achieved when stimulated serum Tg levels were undetectable, in the absence of local recurrence or cervical lymph node metastases on the neck ultrasound. Results: All patients underwent near-total thyroidectomy. The mean age at diagnosis was 49.3 years (range: 18-79 years). There were no statistically significant differences in the histological subtype, the TNM stage, the dose of radioiodine and the time of follow-up, between the two groups. After the RRA treatment, 44 group A patients (88%) were in remission and 6 (12%) in persistence, while in group B 52 (91.2%) were in remission, 1 (1.8%) in persistence and 4 (7%) in recurrence. At their latest follow up (median 87.3 (23.3A cc ep te d A rt ic le This article is protected by copyright. All rights reserved. 251.6 months), all patients were in remission, either as a result of further iodine radioiodine therapy (in 11 patients) or watchful monotoring . Conclusions: The timing of RRA seems to have no effect on the long-term outcome of the disease. Therefore, urgency for radioiodine ablation in low risk thyroid cancer patients is not recommended. Introduction Thyroid cancer is the most common endocrine malignancy with a 2.4-fold increase in incidence over the past 30 years . It is considered an indolent cancer, with a 10-year survival rate over 95% 5, . Despite the generally good prognosis of thyroid carcinoma, about 5% of patients develop metastatic disease, exhibiting a more aggressive course, with a worse prognosis and increased risk of mortality. Standard treatment for well-differentiated thyroid cancer is total or subtotal thyroidectomy followed in many occasions by radioiodine administration, depending on the risk stratification of each patient. The goal of the first dose of radioiodine administration after total thyroidectomy is the ablation of thyroid tissue remnants (RRA) in order to achieve an undetectable serum thyroglobulin level and to irradiate any neoplastic focus in order to decrease the risk of disease recurrence 11, 12 The rising incidence of DTC recorded in recent years, especially of small low-risk thyroid cancer , has led to an increased demand of medical facilities for radioiodine administration. However, due to strict regulations for radioactive protection, in many European countries and Japan radioiodine is administered in a limited number of centers and patients are confronted with delays in receiving their treatment after thyroidectomy. It has been demonstrated that a delay of initial radioiodine administration until more than 180 days after total thyroidectomy in DTC patients with metastases resulted in poor survival , but it is currently unclear whether early RRA offers any benefit compared to late RRA with A cc ep te d A rt ic le This article is protected by copyright. All rights reserved. regard to final outcome in patients with minimal disease, which represent the vast majority of newly diagnosed patients 4, 9, . The aim of our study was to evaluate whether the time interval between surgery and RRA has an effect on the final outcome of patients with early stage well differentiated thyroid cancer.


The article describes the relationship between the organisation of local government in Poland and its competences and responsibilities in the field of ensuring public safety and order to the residents of local communities - municipality, district and province. On the example of selected statutory solutions, it can be stated that at the lowest local government level, the local authority is obliged to a large extent - using or in cooperation with the Police and other institutions independent of the authority - to ensure the safety of residents. It also has basic legal instruments for this. At the provincial and national level, these responsibilities were primarily taken over by the State.


Since the 1980s, a great attention has been paid to the advanced technique remote sensing in China, especially to development of satellite programs for marine environment. On September 7, 1988, China launched her first polar orbit satellite FY-1A for meteorological and oceanographic application (water color and temperature) and second satellite FY-1B two years later. In May 1999, China launched her second generation of environment satellite FY-1C with higher sensitivity, more channels and stable operation. The special ocean color satellite HY-1 has been in the orbit on May 15, 2002, whose main purpose is detection of marine environment of China Sea. HY-1 is a first Chinese ocean color satellite which was launched as a piggyback satellite on FY-1 satellite using Long March rocket. On the satellite there are two sensors, one is the Chinese Ocean Color and Temperature Scanner (COCTS), the other is CCD Coastal Zone Imager (CZI). The technique systems of ocean color remote sensing have been developed by Second Institute of Oceanography (SIO), State Oceanic Administration (SOA), in 1997 and by National Satellite Ocean Application Service (NSOAS) in 2002. Those systems include the functions of data receiving, processing, distribution, calibration, validation and application. SIO has capability to receive and process the FY-1 and AVHRR data since 1989. It is also a SeaWiFS scientific research station authorized by NASA, USA, to freely receive SeaWiFS data Since September 16, 1997. NSOAS has capability to receive and process the data of HY-1, AVHRR, MODIS and Geo satellite. In the recent years, some local algorithms of atmospheric correction and inversion of ocean color are developed for FY-1C , SeaWiFS and HY-1 to improve the accuracy of the measurement from satellites efficiently. The satellite data have being applied in monitoring marine environment, such as the spatial distribution of chlorophyll, primary products, suspended material, transparency and yellow substance, red tide detection and coastal current study.


We propose a new framework for the quantitative assessment of SAR despeckling techniques, based on physical-level simulation of SAR images corresponding to canonical scenes. Thanks to the simulator, we can generate multiple SAR images of the same scene which differ only in the speckle content, and, hence, a true multilook SAR image, with an arbitrarily large number of looks, to use as "speckle-free" reference. Based on this concept, we select a small set of canonical scenes and, for each of them, a suitable set of objective measures which account for speckle suppression and image feature preservation. We gain insight into the system reliability by comparing the indications it gives for some sample despeckling filters with those obtained by expert visual inspection of the filtered images.


This article presents a method and a tool for estimating a global time base from local event traces. These event traces result from monitoring parallel and distributed systems of arbitrary topology, where the processors are working on a common application. The method relies on stability properties of physical clocks and on the causality relationships of cooperating processes. The tool copes with arbitrary communication structures, event trace formats, and any number of different clocks.


Simple, operational tools are required for forest managers to quantify the effects of soil fertility on tree growth and ecosystem sustainability leading to precise, sustainable forest management. The simplified process-based 3-PG model (Landsberg, J.J., and Waring, R.H., For. Ecol. Manage. 95: 209–228, 1997) provides a useful framework for operational prediction of forest growth. However, no simple objective method for relating the effects of available soil nutrients to the model fertility parameter fertility rating (FR) is yet available. The present study aimed to compare several general modeling approaches for the estimation of FR values from soil relative nutrient contents (RNCs) to maximum nonlimiting values, measured in the whole soil profile, at continuous inventory plots of Eucalyptus globulus Labill. in several locations under different parent materials in northwestern Spain. The modeling approaches tested provided good predictions of FR values from RNCs. In particular, using the minimum value of ...


A nanocomposite comprised of Fe3O4 magnetic nanoparticles(MNPs) and multi-walled carbon nanotubes(MWCNTs) was synthesized,and used as adsorbent in the determination of 16 PAEs in water samples by magnetic solid phase extraction(MSPE) and quantification by gas chromatography-mass spectrometry(GC-MS).The synthesis nano material was characterized by Fourier transform infrared spectroscopy.The factors affecting the extraction efficiency,such as type and amount of elution solvent,desorption time,adsorption time and pH value of water sample,were investigated.The optimized conditions were as follows:elution solvent:1 mL toluene-acetone(1 ∶4);desorption time:1 min;adsorption time:3 min;pH of water sample:5.0-7.0.The detection limits(S/N=3) for 16 PAEs were in the range of 0.035-0.255 μg/L and the quantitation limits(S/N=10) were 0.115-0.845 μg/L.The developed method was successfully applied in the analysis of 16 PAEs in tap water,lake water and river water.The recoveries at 3 spiked levels ranged from 87% to 112% with RSDs of 1.3%-11.9%.The results demonstrated that the MSPE method could be rapidly and effectively used in the monitoring of trace PAEs contaminants in water sample.


The anti-hepatitis B virus (HBV) activity of (-)-cis-5-fluoro-1-[2-(hydroxymethyl)-1,3-oxathiolan-5-yl]cytosine (524W91) in cultures of primary human hepatocytes was examined. 524W91 was anabolized to the active 5'-triphosphate in these cells. HBV replication was equally inhibited in cultures incubated with 524W91 when the drug was added 24 h preinfection, at infection, or 24 h postinfection. 524W91 inhibited HBV replication by 50% at less than 20 nM in human hepatocytes.

Oxidative aging causes hardening of asphalt binders and, consequently, contributes to deterioration of asphalt pavements. Non-load related cracking of asphalt pavements (i.e., transverse and block cracks) is related to original properties and hardening of the asphalt binder. In recent years, researchers have proposed new indices derived from Superpave Performance Graded (PG) testing to identify changes in asphalt cracking susceptibility with aging. These indices include the parameter G′/(η′/G′) and the difference between continuous low temperature binder grade measured via Superpave creep stiffness and m-value (ΔTc). This study aims to develop interrelationships between tests allowing choice selection for the determination of simpler parameters that could be used for specification tests of asphalt binders. Two simpler asphalt binder indices for cracking resistance are investigated by means of Dynamic Shear Rheometer (DSR), Bending Beam Rheometer (BBR) and Single Edge Notched Bending (SENB) tests results. At intermediate temperatures, the slope of the |G*|-frequency curve obtained from a simple frequency sweep test is proposed as an alternative approach to directly calculate the durability parameter G′/(η′/G′). At low temperatures, results indicated a direct correlation between failure energy at fracture obtained from SENB and ΔTc. To confim the validity of these indices and the changes at molecular level, Gel Permeation Chromatograph (GPC) results are presented to indicate that asphalts with higher content of large molecular size (LMS) molecules are likely to crack. Limits for specifcations for the slope of |G*|-frequency curve and ΔTc can be derived based on testing a wide range of binders and field experience.


A high-performance implementation of a Java Virtual Machine1 requires a compiler to translate Java bytecodes into native instructions, as well as an advanced garbage collector (e.g., copying or generational). When the Java heap is exhausted and the garbage collector executes, the compiler must report to the garbage collector all live object references contained in physical registers and stack locations. Typical compilers only allow certain instructions (e.g., call instructions and backward branches) to be GC-safe; if GC happens at some other instruction, the compiler may need to advance execution to the next GC-safe point. Until now, no one has ever attempted to make every compiler-generated instruction GC-safe, due to the perception that recording this information would require too much space. This kind of support could improve the GC performance in multithreaded applications. We show how to use simple compression techniques to reduce the size of the GC map to about 20% of the generated code size, a result that is competitive with the best previously published results. In addition, we extend the work of Agesen, Detlefs, and Moss, regarding the so-called "JSR Problem" (the single exception to Java's type safety property), in a way that eliminates the need for extra runtime overhead in the generated code.


635 Background: HER2-overexpressing or triple-negative [ER(-)/PR(-)/HER2(-)] breast cancers are associated with increased risk of brain metastases. The mechanisms leading to metastasis in each subtype are not well known. Methods: We introduced the wild-type HER2 gene into MDA-MB-231-luc-D3H2LN (231-Luc) cells, which are triple-negative breast cancer cells, and established HER2-expressing (63.2%) cells as 231-Luc-HER2 cells. We investigated the tumor formation following orthotopic inoculation and brain metastasis following intracardiac injection into nude mice. Metastasis was detected by bioluminescence imaging and confirmed in H&E staining and immunohistochemistry of vimentin and HER2 expressions. Flow cytometry analysis was used to detect the proportion of CD44+/CD24- cells, a maker for stem-like breast cancer cells. Results: 231-Luc-HER2 cells formed larger tumors in orthotopic xenograft models compared to 231-Luc cells, however, no significant difference was observed in proliferation in vitro. Neither ...


The effects of river works and harbor constructions under tidal flow conditions are determined using numerical and physical models. For the harbor extension Altenwerder, now be- ing under construction, and the reconstruction of the Hansahafen both in Hamburg, Germany, dif- ferent designs of harbor geometries were analyzed with respect to flow characteristics and sedi- mentation conditions. A comparison of the results reveals a good agreement of the flow condi- tions between numerical and physical models.

In the first part, an experimental identification method of impact force is developed where the relation between force histories and strain responses is determined experimentally. By employing this relation, the impact force is identified for CFRP laminated plates involving impact damages under a drop-weight impact test. It is shown that the identified force history agrees well with the experimental one even when the impact damage is induced. Next, the impact damage monitoring method is proposed. When the information on the maximum impact force is obtained, the occurrence of the impact damage can be predicted easily from the shape of force history, and the damage size can also be estimated using the experimental relation between the damage size and the maximum impact force. Thus, structural health can be evaluated automatically, by monitoring the impact force from the sensor response in real time, and great improvement of the structure safety becomes possible.


Schistosomias is a prevalent parasitic disease in tropical and sub-tropical areas, which comes in the second place in terms of socioeconomic and public health burden. Around 600 million people in 74 countries are infected yearly, predominantly in the developing world. The aim of this work was to assess the efficiency of three extracts from Carica papaya (methanol, ethanol and butanol extracts) Original Research Article Aly et al.; JPRI, 32(11): 31-41, 2020; Article no.JPRI.58620 32 for their molluscicidal and anti-schistosomal activities. The LC50 of methanol, ethanol and butanol extracts of Carica papaya against B. alexandrinea were 180, 499.3 and 509.1 mg/L while the respective LC90 values were 220.3, 700.6, 769.6 mg/L respectively. The effect of these extracts on Biomphalaria alexandrina snails and larval stages of Schistosma mansoni, for miracidia the LC50 of methanol, ethanol and butanol extracts of Carica papaya against miracidia were 3.4, 15.4 and 8.1 mg/L, respectively, while the respective LC90 values were 8.4, 38.2, 11.2 mg/L, and for cercariae the LC50 of methanol, ethanol and butanol extracts of Carica papaya were 2, 20 and 4 mg/L, while the respective LC90 values were 13.5, 80.5, 18.5 mg/L respectively was evaluated, in addition to flowcytometric analysis of CD4, CD25, FOXP3 and TGF-β levels during S. mansoni infection in mice. The in-vivo results showed that the three extracts have variable potential against snails and miracidia and cercariae of S. mansoni. The mortality rate in B. alexandrina snails for methanol, ethanol and butanol extracts of Carcia papay were 86%, 45% and 64%, respectively. While it was 83%, 35% and 66%, respectively in miracidia and 92%, 40% and 70%, respectively in cercariae. The results indicated that methanol extract from Carica papaya recorded higher activity against snails, miracidia and cercariae. The levels of CD4, CD25, FOXP3 regulatory T (Treg) cells were decreased significantly (p<0.001) in infected mice compared to healthy controls. However, there was a significant (p<0.001) increase in levels of TGF-β. A significant increase in the levels of CD4, CD25, and FOXP3 Treg in Carica papaya treated group compared to infected control group, with a significant (p<0.001) decrease in TGF-β level than infected group. In conclusion, methanol extract was more effective at concentration of LC50 180 and LC90 220.3 than ethanol and butanol extracts of Carica papaya therefore controlling B. alexandrina snails by methanol extract is a promising way as it is an eco-friendly strategy in rural areas of developing countries, where schistosomiasis is endemic. Moreover, the increased immune defense mechanism in treated group with the same extracts is a promising target for new immune modulatory strategies against schistosomiasis.


Aspect of social conflict that needs to be considered is violence arising from social conflict. Conflict management aims at preventing how violence does not occur and conflict parties can handle and resolve their conflicts without using violence. Government Regulation Number 2 Year 2015 concerning Act Implementing Regulation Number 7 2012 concerning Handling Social Conflict was made to protect and provide a more optimal sense of community security. Government regions in preventing conflicts optimize peaceful dispute resolution through deliberation for consensus and can involve participation of the society.


The map area lies at the north of Halls Bay, Notre Dame Bay in the Central Mobile Belt of Newfoundland, i.e., at the northeastern extremity of the Appalachian mountain system. -- The map units consist of a south-dipping, south-facing pile of Ordovician pillow lavas, pyroclastics and volcaniclastic sediments approximately 17,000 feet in thickness. There is a lateral facies change from predominantly pyroclastics with minor lava tongues in the northwest to predominantly lava with intercalated discontinuous lenses of pyroclastics in the southeast. -- The pyroclastics and volcaniclastic sediments are mainly intermediate-composition reworked tuffs with common agglomeratic horizons. There are minor lenses of acid pyroclastics and pseudo-iron formation. -- The flows vary from massive, glassy pillow basalt, crystalline pillow basalt and associated pillow breccia with rare intercalated pyroclastics or sediments at the base to highly vesicular and porphyritic pillowed andesites with numerous and in places thick intercalated pyroclastic lenses. Chemically the flows form two distinct chemical groups corresponding to the stratigraphic level in the pile thus suggesting a general but consistent differentiation sequence from the lower basalts to the upper andesites. The chemistry and stratigraphy suggest that the succession is of island-arc affinity rather than oceanic affinity. -- Each type or group has a mineral assemblage characteristic of the lower greenschist facies epidotite, chlorite, actinolite, calcite, albite; however, the originally igneous mineralogy can generally be recognized. -- A shallowing environment is suggested by the presence of shallow water limestone and limestone breccias and current bedded greywackes near the top of the sequence. However, the recurrence of pillow-lavas and reworked tuffs above this unit suggest either not a completely emergence or a resubmergence. -- The early gabbro, diabase and andesite type intrusions predate the regional, probably Acadian deformation and are probably genetically related to the volcanism. The Long Island pluton and quartz-feldspar porphyries are post-deformation. -- One phase of regional deformation is represented by a locally or zonally developed steep, generally E-W penetrative cleavage. This cleavage is obscured and/or intensified by faulting in the southern area of Long Island. Small scale folds, angular relationships and cleavage-bedding relationships combined with stratigraphic tops suggest that the sequence occupies the south limb of a west plunging anticline. Kink bands fold the earlier fabric but are restricted to fault zones and may be related to faulting. Similarly minor local crenulations of the first cleavage seem to be related to intrusions.

Interventions for resilience to stress can be effective but are typically time intensive. With contemporary life demands, effective, brief interventions may be advantageous. Methods: This single arm, mixed methods study evaluated the effectiveness of a 1-day resilience to stress training course. Thirty community participants were surveyed at baseline and 1-month. Qualitative interviews were conducted between 30-68 days postintervention according to a grounded theory approach. Quantitative measures included perceived stress scale (PSS), public health surveillance well-being (PHS-WB), rand medical outcome survey (MOS) SF-36, health, and productivity questionnaire (HPQ), work productivity and activity impairment (WPAI) and brief cope scale (BCS). Participants had a mean age of 53-years (SD=9) and were largely female (57%), caucasian (79%), married (83%), and employed (80%). Generalized estimating equations and paired sample t-tests were used to analyze quantitative data. Results: Participants self-reported improvement at 1-month on the PSS (moderate or high 100% vs. 50%, p<0.001), PHS-WB (29.8 vs. 31.5, p=.04), SF-36 subscales role limitation due to physical health (44.1 vs. 69.0, p=.002), vitality (55.2 vs. 63.6, p=.008), emotional well-being (70.9 vs. 78.0, p=0.001), and social functioning (76.0 vs. 87.9, p=0.003). Qualitative analysis suggested participants used the course as an opportunity to build a framework for action. Critical ideas triggered a recalibration of perspectives and reference points (i.e., mindsets) opening the way to updating routinized decisions and harnessing new ways of behaving in service of resilience. Embedding changes in behavior were swift for some or a gradual process of pragmatic adaption for others. Conclusions: Our pilot findings suggest that brief one-day interventions may facilitate personal reform and may enhance resilience and psychological well-being. Longer follows-ups to determine sustainability are also required.


In‐line probing (Regulski, E.E. and Breaker, R.R., (2008) Methods Mol. Biol. 419, 53) provides a straightforward method for probing RNA structure. We have used this technique to characterize the human mitochondrial tRNAAla and four tRNA mutants associated with mitochondrial pathologies, including MERFF (myoclonic epilepsy with ragged red fibers), ophthalmoplegia, and mitochondrial myopathy. Our data suggests that two of these mutants, C5650T and A5628G, adopt abnormal secondary structures at room temperature, which may lead to reduced aminoacylation levels. This work was supported by Carleton College and the Howard Hughes Medical Institute.


Community pharmacies can only be owned by pharmacists, as enforced in the Law 16/1997, 25 th April (Regulation of Community Pharmacy Services). Nevertheless, the continuity right allows a unique exception, which can also comprise the titular reservation (a special situation). A concise summary of the origin and development of this rule is presented. The situation in Spain nowadays is characterized as highly variable mainly due to the fact that autonomic governments are responsible for the pharmacy ordinance.


Neural style transfer draws researchers' attention, but the interest focuses on bitmap images. Various models have been developed for bitmap image generation both online and offline with arbitrary and pre-trained styles. However, the style transfer between vector images has not almost been considered. Our research shows that applying standard content and style losses insignificantly changes the vector image drawing style because the structure of vector primitives differs a lot from pixels. To handle this problem, we introduce new loss functions. We also develop a new method based on differentiable rasterization that uses these loss functions and can change the color and shape parameters of the content image corresponding to the drawing of the style image. Qualitative experiments demonstrate the effectiveness of the proposed VectorNST method compared with the state-of-the-art neural style transfer approaches for bitmap images and the only existing approach for stylizing vector images, DiffVG. Although the proposed model does not achieve the quality and smoothness of style transfer between bitmap images, we consider our work an important early step in this area. VectorNST code and demo service are available at https://github.com/IzhanVarsky/VectorNST.

A modified version of the first-order logic of probability presented in (Halpern 1990) - with probability on possible worlds - makes it possible to formulate an alternative characterisation of fuzzy sets. In this approach, fuzzy sets are no longer seen as primitive entities with an intuitive justification, but rather as structured entities emerging in a suitable logical framework. Some fuzzy techniques of practical relevance are shown to be encodable in this way. In addition, the resulting approach leads to a clearer epistemological analysis in that it clarifies the purposive nature of the kind of uncertainty that can be modelled by fuzziness.


Three parameterizations DOPS1, DOPS2, and DOPS3 (named after the Department of Physics Shimla) of the Relativistic Mean Field (RMF) model have been proposed with the inclusion of all possible self and mixed interactions between the scalar-isoscalar (\sigma), vector-isoscalar (\omega) and vector-isovector (\rho) mesons up to quartic order. The generated parameter sets are in harmony with the finite and bulk nuclear matter properties. A set of Equations of State (EOSs) composed of pure hadronic (nucleonic) matter and nucleonic with quark matter (hybrid EOSs) for superdense hadron-quark matter in \beta-equilibrium is obtained. The quark matter phase is calculated by using the three-flavor Nambu-Jona-Lasinio (NJL) model. The maximum mass of a non-rotating neutron star with DOPS1 parameterization is found to be around 2.6 M$\odot$ for the pure nucleonic matter which satisfies the recent gravitational wave analysis of GW190814 Abbott et al.,(2020) with possible maximum mass constraint indicating that the secondary component of GW190814 could be a non-rotating heaviest neutron star composed of pure nucleonic matter. EOSs computed with the DOPS2 and DOPS3 parameterizations satisfy the X-Ray observational data and the recent observations of GW170817 maximum mass constraint of a stable non-rotating neutron star in the range 2.01 \pm 0.04 - 2.16 \pm 0.03 M\odot and also in good agreement with constraints on mass and radius measurement for PSR J0740+6620 (NICER) Riley et al., L27 (2021)}, Miller et al., (2021). The hybrid EOSs obtained with the NJL model also satisfy astrophysical constraints on the maximum mass of a neutron star from PSR J1614-2230 and Demorest et al., (2010) .We also present the results for dimensionless tidal deformability, ${\Lambda}$ which are consistent with the waveform models analysis of GW170817.

Copper-catalyzed reaction of arenethiols (I) with aryl iodides (II) and bromides (IV) proceeds with thioether formation and concomitant ortho-hydroxylation of the thiol-derived aryl ring.


Although it is well known that vertebrates universally use the chromatophore to control their body color patterns, the difference of chromatophore types within vertebrates were observed: mammals have one single chromatophore type while fish could possess six types of chromatophores. To better understand the molecular mechanisms underlying the chromatophore diversity in fish, the genomic resources and data of four fish species, Cynoglossus semilaevis, Danio rerio(zebrafish), Oreochromis niloticus and Paralichthys olivaceus, including whole-genome sequence, annotation, and transcription data, were exploited. A total of 61 pigmentation-related genes were identified in all studied species and classified into six groups including the Mcr gene family group, which plays the most important role in melanocortin system. The numbers of each pigmentation-related gene family members are similar across all four species, except Mc3r gene is only found in zebrafish genome. Comparative analysis of pigmentation-related genes structures and phylogenetic analysis provide a clear orthologous relationship for all Mcr genes. For Danio rerio and Cynoglossus semilaevis, using the skin samples from different developmental stages, the transcriptome analyses revealeda diverse expression pattern across all pigmentation-related genes and Dbh and Hbxd3a genes highly co-expressed with multiple pigmentation-related genes. The STRING analysis of pigmentation-related proteins in zebrafish demonstrates that five proteins, corticotrophin releasing hormone, oxytocin-like protein, opioid receptor (delta), prepronociceptin α and β have strong interactions with pigmentation-related proteins. This work provides a better understanding of compositions of pigmentation-related genes in four fish species and provides insights on the far-reaching genetic mechanism of chromatophore-controlled pigmentation.


structures of polymer electrolyte membranes and catalyst layer binders and the distribution of water therein are important for designing new ion-conductive ionomers for polymer electrolyte fuel cells. To aid the understanding of the in-plane water distribution, neutron re fl ectometry (NR) was carried out on a Na fi on ® fi lm with a thickness of 150nm formed on a 20-nm Pt layer deposited on Si(100) with a native SiO 2 layer. By means of ambient pressure X-ray absorption spectroscopy at room temperature in air, the Pt substrate was found to be metallic. For NR, the temperature was set at 80°C and the relative humidity at 30, 50 and 80%, simulating the conditions for power generation. Clear NR modulation was obtained under each condition. NR data were fi t very well with a 3-sublayered model parallel to the substrate with di ff erent densities of Na fi on and water. The in fl uence of the Pt substrate was observed not only at the Na fi on/Pt interface, but also on the thin- fi lm structure. The water uptake in a Na fi on fi lm on Pt also di ff ered from that on SiO 2 . At 80°C, the surface of the Pt substrate was proposed to be oxidized, and the Na fi on/Pt interface was found to contain water, in contrast to the interface observed at room temperature.


The objective of the Regional Fisheries Programme for West Africa (PRAO-Guinea) is to increase sustainable manner all of the wealth generated by the exploitation of fishery resources in the countries of West Africa, by: (i) reducing illegal fishing (ii) developing the capacity of countries to govern and sustainably manage their fisheries, and (iii) increasing the value and profits from fishery products and the share of that value captured by these countries. Some of the negative impacts include: fisheries and related activities; fish processing; management of infrastructure and services; storage and handling of fuels or other products; repair and maintenance of ships and artisanal canoes; effluent disposal; disposal of solid waste; public access; fisheries management; drinking water deficit; lack of sanitation; etc.


Any subset of reality can potentially be interpreted as a computer, so when we speak about a particular computer, we are merely speaking about a portion of reality we can understand computationally. That means that computation is only identifiable through the human experience of it. User interface is ultimately the only grounding for the abstractions of computation, in the same way that the measurement of physical phenomena provides the only legitimate basis for physics. But user interface also changes humans. As computation is perceived, the natures of self and personhood are transformed. This process, when designers are aware of it, can be understood as an emerging form of applied philosophy or even applied spirituality.


Human capital introduction investment is a kind of investment with high risk.In order to avoid the investment misplay and to insure an expected investment income,enterprises must evaluate the investment feasibility before they introduce human capital.With the guidance of the theory of feasibility study,an feasibility evaluation index system of human capital introduction investment in enterprises that consists of three aspects—the feasibility of the quality of human capital,the feasibility of the interior environment of enterprises and the feasibility of the investment benefit—is constructed in this thesis,and the steps of the feasibility evaluation of human capital introduction investment are put forward on the basis of the multilevel grey evaluation method,and an application example is showed.

Coleoptera is the most species-rich order among the Insecta and although only 4% of its species are aquatic, it is an abundant group in the freshwater environments. This work aims to expand knowledge of the group primarily in lotic systems. Are proposed identification keys for larvae and adults of 17 families of aquatic Coleoptera known from the state, to assist researchers who are unfamiliar with the identification of this group. All material studied was collected in Sao Paulo, Brazil as part of the BIOTA/FAPESP Program.


little mutilation one may imply as compared with another operation. But while wve admit the necessity and admire the wisdom of reforming the body politic to yet higher states of efficiency, the human body endowed with the power of growth, development, ancl restoration-is self-productive and self-protective; wlherefor-e we need not interfere with its oranisation otherwise than so far only as our assistance is solicited by the shortcomings of its own operations and the failure of its own resources. The subjection and adaptation of all therapeutics-in time, kind, and deree-to the operation and requirements of this self-restorative power (of Nature) confer a truly conservative character on the practice alike of medicine and surgery; and, by ever referring us, as medical practitioners of whalltever denomination, to clinical observation of the natural courses and tendencies of injurie3 and diseases, rule our art from the suire and commanding grouid of pwahology. To this elnd, diagnosis and etiological knowledge, each of the earliest and most exact character, are obviously subservient.


To observe the effect of gastric filling on the images of hepatic scintigraphy, we performed hepatic scintigraphy using colloid in twenty patients both in the fasting state and after meal, and made the visual comparison of both images. We found that gastric filling could cause some of the following changes in individual patients. 1) In the anterior view, the distance between the liver and the spleen increased and the interlobar notch of the inferior hepatic border was obliterated. The spleen was displaced downwards, its radioactivity in the upper medial part was reduced, and its upper pole was laterally displaced. 2) In the posterior view, the left lobe of the liver was separated from the spleen and the distance between the liver and the spleen increased. 3) In the right lateral view, the notch separating the right and the left lobes of the liver was well demarcated. 4) In the left lateral view, the spleen was separated from the liver and the distance between the liver and the spleen increased. The shape of the spleen was also changed. In case of the follow-up study, above changes should make one consider the possibility of the effect of gastric filling.


Internet-enabled technology can be empowering for victims of domestic violence, by providing them with education, information and expanded networks of social support, technology use can also become a source of vulnerability for women and girls. Instead of being empowered by technology, some women are being driven away from women's refuge in Canberra, cited in Francis, 2015.
it by the rise of both cyber misogyny and digital domestic violence. When female victims are pushed offline their ability to participate effectively in a digital society and economy is severely undermined and women as a group are further excluded from positions of influence in the public sphere. Increasingly, enabling women and girls to take control of their 'real' lives and relationships, requires encouraging them to take control of their digital lives and relationships, through mastering new communication technologies in cultural and political contexts.


Learning a new language depends on so many factors such as learners, teachers, environment, purpose of learning or teaching, and more importantly textbooks. Textbooks are a key component in most language programs. For most teachers, textbooks provide the foundation for the content of lessons, the balance of the skills taught, as well as the kinds of language practice the students engage in during class activities. This paper aims to evaluate the authenticity of the Iranian English textbooks at high school level. It is based on Dougills' textbook evaluation checklist. According to the feedback received from the teachers' and the students' responses, the home-made textbooks lack the authenticity of natural English in terms of content and presentation. They are short in the variety and attractiveness in the passages. The materials are not generally presented from the easy to hard order and they are mainly void of cultural and communicative points.


Half of Bosnia and Herzegovina's (BH) population lives in rural areas. Agricultural production is a backbone of the rural economy and generates significant economic value for the country. BH is highly vulnerable to climate change, which poses a significant development challenge given the climate-sensitivity of the agricultural sector, the share of agriculture in the total economy, the number of people employed in the sector, and the closely related socio-economic issues of food security. BH has experienced serious incidences of extreme weather events over the past two decades, causing severe economic losses. Based on available data and currently available climate projections, exposure to threats from climate change will continue to increase. The review paper presents the current state of the BH agricultural sector and the impact of potential climate change on agricultural systems. It proposes policy options to optimize opportunities and mitigate consequences of possible climate change in the agricultural sector. Development of policy and research capacity should include harmonisation and centralisation of domestic agricultural policies, carrying out a vulnerability assessment and strengthening the public and private extension systems. Further technological development should include improvements in weather and climate information systems, crop development, irrigation and water management.


Certain unique characteristics of the Indian bookbuilding process allow us to study the timing and subscription pattern of different investor groups and to dissect underpricing into two distinct components: one relating to pre-listing, set by the underwriter and the other from the post-listing period, which is determined by the market. Our results show the presence of sequential learning among IPO investors. Retail and Non-institutional investors follow the Institutional investors' subscription patterns when bidding for shares. The transparency of the bookbuilding process in the Indian IPOs helps alleviate the winner's curse problem for the non-institutional and retail investors. We also show that market underpricing is primarily driven by the unmet demand of the non-institutional investor groups. This insight is unprecedented in the IPO literature.

Krumbiegel, A.: Socialization of Gentianella campestris ssp. baltica at the east bank of the Muritz Lake (Mecklenburg-Western Pomerania) and near Ballenstedt at the north rim of the Harz Mountains (Saxony-Anhalt). – Hercynia N.F. 41 (2008): 219 -238. Gentianella campestris ssp. baltica is a strongly endangered species both in Germany and in Europe. The reason therefore is the intensive land use which caused the decrease of suitable sites. The remaining places of occurrence in Eastern Germany are concentrating in the Harz Mountains and the northern Harz Mountains foreland (Saxony-Anhalt). In Mecklenburg-Western Pomerania the species only occurs with few individuals in the Muritz National Park on the Spukloch enclosure. The site conditions at the northern Harz Mountains erection zone and at the eastern bank of the Muritz Lake are very different. The investigation of the phytosociological behaviour of Gentianella campestris ssp. baltica at the different sites shall contribute to a better knowledge about the species. Whereas lake sand partly with embedded peat is common on the Spukloch enclosure, which is a terrace of the Muritz Lake, Gentianella campestris ssp. baltica grows on withering substrates of Cretaceous sandstone near the Gegensteine (erection zone of the northern Harz Mountains rim). Two small partial populations of Gentianella campestris ssp. baltica are known on the Spukloch enclosure at present. They show a very broad range of phytosociologically different species. Molinietalia species, indicating moisture and changing moisture conditions, respectively are remarkable at the one place. On contrary, Festuco-Brometea species, indicating dry conditions are of interest at the other place of occurrence. Nardo-Callunetea, Molinio-Arrhenatheretea, Arrhenatheretalia, Brometalia erecti, Arrhenatherion and Cynosurion species add the species inventory on both sites. The phytosociological characterization of Gentianella campestris ssp. baltica on the Spukloch enclosure is difficult because of the very different accompanying species. The vegetation can be classified as poor Arrhenatheretalia basal community most likely and as Festuco rubrae-Cynosuretum cristati R. Tx. in Buker 1942, respectively. The moister place also shows a very diverse species composition, so that it can be characterized as Molinion-Cynosurion-Arrhenatherion mixed stand. The spatial adjacencies to the Parnassio palustris- Molinietum caeruleae suggests the belonging of Gentianella campestris ssp. baltica to this assoziation, too. However, this must still become confirmed with specific releves. Gentianella campestris ssp. baltica occurs on dry stands around the Gegensteine at the north Harz Mountains rim. Its sites are characterized by Festuco-Brometea-, especially Mesobromion- as well as Nardo-Callunetea-species, and other common species of anthropo-zoogenic heaths and lawns with higher abundance. One of the three stands (Schierberge) can be classified as a transition between Arrhenatherion elatius and Galio-Agrostidetum Mahn 1965 with respect to the rather high amount of Arrhenatheretalia- and Molinio-Arrhenatheretea species. Secondly Gentianlla campestris ssp. baltica occurs within grass rich Euphorbio-Callunetum Schub. 1960 em. Schub. 1995 below the rock formation of the Gegensteine. At the third place (between Gegensteine and Schierberge) the species grows very scattered in denser and higher vegetation (Festuco rupicolae-Brachypodietum pinnati Mahn 1959 em. Schub. 1995). A comparison between Ellenberg indicator values and such values, determined by means of the accompanying species of the releves showed both rather good correspondency (temperature, [light, continentality]) and clear differences (moisture, soil reaction) based on the average of al 20 vegetation releves. The ascertained fertility value (3,5) clearly shows the species' preference of poor stands, however an Ellenberg indicator value of fertility does not exist. Gentianella campestris ssp. baltica is a therophyte. Thus it depends on of scattered, low vegetation which allows annual reproduction from seed. This is illustrated by the one place of occurrence on the Spukloch enclosure, where Gentianella campestris ssp. baltica grows on a cattle track. Similar conditions on principle exist below the rock formation of the Gegensteine, where the grassland and heath are partly mown very near to the ground including soil damage. Extensive grazing or (occasional) mowing for nature protection purposes therefore contributes to conservation or facilitation of the species. Key words: endangered species, poor grassland, Molinion alliance, dry heaths, indicator values, extensive land use


In applications ranging from video reception to telecommunications and packet communication to aircraft control, tasks enter periodically and have fixed response time constraints, but missing a deadline is acceptable, provided most deadlines are met. We call such tasks "occasionally skippable". We look at the problem of uniprocessor scheduling of occasionally skippable periodic tasks in an environment having periodic tasks. We show that making optimal use of skips is NP-hard. We then look at two algorithms called Skip-Over Algorithms (one a variant of earliest deadline first and one of rate monotonic scheduling) that exploit skips. We give schedulability bounds for both.


Abstract We compare the geometric concept of strict convexity of open subsets of Rn with the analytic concept of 2-strict convexity, which is based on the defining functions of the set, and we do this by introducing the class of 2N-strictly convex sets. We also describe an exhaustion process of convex sets by a sequence of 2-strictly convex sets.


The term" electronic-services" or as it was renamed e-services have become recently more interested by even the ordinary people. Assessing its levels is considered to be an important criteria for estimating the e-performance of all types and levels of organizations and then to rearrange all countries over the world into such a hierarchy measure or reasonable map showing their economical , scientific , and development ranks among others. Reaching to the maturity stage of e-services model however, means improving its quality and developing its delivery manner and moreover, converging to more people of community. The aim of this study is to evaluate the Iraqi experience in terms of e-services trying to assess its stage in the shadow of the maturity model along with its type and to identify the challenges that face its way toward achieving its goals. Moreover this study suggested some solutions to decrease the effects of its challenges and to improve the Ministry of Science and Technology (the sponsor of e-Government project) performance technically and economically. Most of the Information, figures , and facts have been gained from the printed lectures that have been offered through the Iraqi e-government training of trainers courses by UNIP specialized experts which have been held in Jordon on 2011.Those lectures have been very useful documents and was a good source of evaluating criteria supporting our assessment.


This research outlines the concept of resurrection from the ancient Hebrew Torah to Rabbinic Judaism and Christianity according to authoritative and linguistically accurate scriptures accompanied by English translations. Although some contemporary scholars are of the opinion that resurrection is vaguely portrayed in the Hebrew Torah, our research into the ancient texts offers quotes and provides proofs to the contrary. With the passing time, the concept of the resurrection grew even stronger and became one of the most important doctrines of Judaism, enjoined as one of the thirteen articles of faith by Maimonides in the Mishnah. Imitative of the Jewish concept of God reaching out to save Israelites from gehenna, Jesus' crucifixion and death for the sins of the world, resurrection on the third day, descend into the hells and subsequent rise into heavens became the essential foundation of Christianity, with Christ's resurrection as the impetus for the resurrection of those who believe in him. According to this Pauline theology, Christian faith is based upon the resurrection of Jesus and the hope for a life after death.


BackgroundHyperthermia is one of the most common therapy for tumor, in which temperature monitoring is essential. Invasive temperature monitoring is mostly used in clinic at present, which leads to limited points under monitoring and extra hurt to patients. Therefore, noninvasive temperature estimation is a key and tough problem in hyperthermia. In this paper, a noninvasive temperature estimation method for hyperthermia based on B-mode ultrasonic image with wavelet transform and texture analysis is proposed.MethodsAnimal tissue both in vitro and in vivo(pig kidneys in vitro and rabbit kidney in vivo) were taken as experimental materials. Ultrasound images and temperature data were collected from radio frequency ablation experiment under approved protocol. Image subtraction and wavelet transform were performed on the ultrasound images to enhance the change during ablation, after which texture features were extracted to analyze the relationship with temperature.ResultsTexture features hybrid entropy and energy extracted from gray-level gradient co-occurrence matrix of ultrasound images processed had higher linear correlation with temperature than traditional gray value method. From in vitro and in vivo experiments, the linear correlation coefficients obtained between hybrid entropy and temperature were 0.979±0.028 and -0.935±0.037, respectively, and those between energy and temperature were 0.932±0.056 and -0.915±0.034, respectively. In addition, the slopes of linear model obtained in vitro were relatively consistent, while those under in vivo condition had certain individual differences.ConclusionsThe results demonstrated that texture features hybrid entropy and energy of ultrasound image processed with the method proposed in this paper can be used for temperature estimation with a smaller error because of high linear correlation with temperature both in vitro and in vivo. Compared with most previous research which only based on biomaterial in vitro, the in vivo experiment conducted in this paper verified the feasibility of the noninvasive temperature estimation method proposed in practice.


13C NMR contact shifts induced by the 2,2,6,6,‐tetramethylpiperidine nitroxide radical (TMPN) were measured for N,N‐dimethyl‐para‐substituted benzamides and N,N‐dimethyl‐β‐bromo‐ and ‐α,β‐methylacrylamides. The shifts were linear functions of radical concentration, cr. It was found that N‐methyl group anti to the carbonyl group is a better acceptor site than the syn‐N‐methyl group and that there is a relationship between Δδ/dcr and the non‐planarity of molecules of amides with an s‐skew conformation. The electrostatic potential of amide molecules obtained from MNDO calculations was used to predict the stereospecific interaction with radicals.

The occurrence of the Old English negative particle ne 'not' preceding a bare infinitive rather than a finite verb is a largely neglected or overlooked phenomenon. It is attested in constructions with uton 'let's' and in conjoined clauses with omission of the finite verb (Mitchell 1985). This article discusses evidence gathered mainly from the York–Toronto– Helsinki Parsed Corpus of Old English Prose , showing that it is a phenomenon that needs to be taken seriously in descriptions and analyses of Old English. It is argued that the factor shared by the two constructions is the lack of an available finite verb for ne to attach to. It is also found that the use of ne for the purpose of negative concord appears to be more variable with infinitives than it is with finite verbs. Whether attachment of ne to a non-finite verb in the absence of a finite one is restricted to bare infinitives is difficult to determine because of the limited evidence relating to other non-finite forms, but there are some indications that use of ne may have been possible with present participles. Finally, some implications that the ne + infinitive pattern has for the formal analysis of Old English are discussed.


Identifying the native language of a person by their text written in English (L1 identification) plays an important role in such tasks as authorship profiling and identification. With the current proliferation of misinformation in social media, these methods are especially topical. Most studies in this field have focused on the development of supervised classification algorithms, that are trained on a single L1 dataset. Although multiple labeled datasets are available for L1 iden-tification, they contain texts authored by speakers of different languages and do not completely overlap. Current approaches achieve high accuracy on available datasets, but this is attained by training an individual classifier for each dataset. Studies show that joint training of multiple classifiers on different datasets can result in sharing information between the classifiers, leading to an increase in the accuracy of both tasks. In this study, we develop a novel deep neural network (DNN) architecture for L1 classification; it is based on an adversarial multitask learning method that integrates shared knowledge from multiple L1 datasets. We propose several variants of the architecture and rigorously evaluate their


The aim of this article is to reevaluate some elements of literature on Central Asian regionalism through the prism of contemporary regionalism theories elaborated by international epistemic community of regional scholars. Firstly, it will briefly present contemporary regionalism as a phenomenon and a discipline. It will then advance an analytical framework of regional order. The second part will give a short introduction of post-Soviet and Central Asian regionalisms. It will then argue that the analytical framework presented on the first section should be applied to Central Asian case to make sense of regionalism processes there. As a conclusion, I will argue that we should move from "Central Asian regional integration debate" to discussions around "Eurasian integration space."


ABSTRACT

Refactor the traditional marine engine room simulator (MERS) and a corresponding marine engine room (MER) three-dimensional (3-D) visual simulation system is integrated with it. The whole virtual MER scene is modeled by using 3D-Max and rendered by using Vray. Optimization methods including texture mapping and level of detail (LOD) technique are adopted to improve the user overall experience. Aiming at the enormous amount of interaction entities in MER, behavior modeling is adopted to classify all the interaction entities into several types and corresponding general interaction scripts are designed. Optimize the traditional 3-D picking algorithm by taking the horizontal occupation percentage of the picked-up object's bounding sphere in the final rendering graphics to improve the pick accuracy.To enhance the practicability of the training system developed in this paper, auxiliary functions including navigation, information display and MER virtual panoramic map are developed to facilitate the training process. At last, an automatically evaluation function based on fuzzy comprehend evaluation method is developed to substitute the traditional manual evaluation. The MER 3-D visual simulation system developed in this paper has been applied in the education, training and evaluation tasks in several maritime colleges and training institutions in China.


There is an inherent contradiction in the existing system of mass education, where each class period is devoted to a new subject every student comes to class with their individual interest, but the teacher does not consider these differences and teaches everyone the same. The author calls this fundamental contradiction of the existing educational system and offers a resolution of this contradiction.

A variety of challenges are being faced nowadays of network intrusion which is continually increasing. These are due to vulnerabilities in software, hardware, and network protocols. Therefore, stronger IDS is required; ML and DM have further strengthened the IDS technology. At the same time threat has also become more sophisticated. Now overfitting and structured optimization techniques are used in IDS. In this paper, we proposed a deep neural network-based IDS. The DL based system monitors the traffic coming from authentic and non-authentic sources. It classifies and segregates malicious traffic with accuracy up to 99.78used for experimentation and comparative analysis with previous techniques shows encouraging results.

Across the last few chapters, we have seen various layers of evidence affirming the political influence of implicit attitudes among individual citizens. By necessity, these efforts have centered on the psychological processes behind implicit attitudes. Yet by focusing on the inner recesses of the mind, the fact that individuals are embedded within a larger social structure has been minimized, if not eliminated, from our investigations so far. This can potentially give the wrong impression about implicit attitudes. At its worst, it insinuates that implicit biases like these are strictly a matter of individual predisposition or temperament, mostly, if not completely, divorced from the social landscape in which he or she is inserted. This chapter endeavors to correct this omission by shedding light on the social foundations of implicit attitude: a feat I accomplish by centering on the role of race. Race has often been at the center of America's politics and institutions (e.g., Marx 1998; McClain and Stewart 2005). At America's inception, for example, race was used to systematically exclude black Americans from the nation through active denial of citizenship (Smith 1997). This policy continued through the Civil War until passage of the 14th Amendment, which broadened the definition of citizenship to include this group. Yet in spite of constitutional reforms, informal institutions and practices (e.g., Jim Crow) sustained many of the same attitudes, norms, and practices that had thrived under de jure racial exclusion. Race continued to matter. In fact, even today, nearly five decades after the 1964 Civil Rights Act officially ended discriminatory practices like housing segregation and voter fraud, race still matters. For many individuals, their outcomes continue to be profoundly shaped by whether they happen to be black or not, as evidenced by the starkly higher rates of incarceration and poverty within the larger African American community, for example (Brown-Dean 2007; Conley 1999). Of course, this is not to say that American race relations have not genuinely changed. Progress has been made – and is being made – on many, if not all, of these fronts. We are definitely not the nation of yesteryear. But to focus exclusively on aggregate improvements in the standing of African Americans is to risk missing an enduring but critical insight about black individuals. Even in the face of collective progress, race continues to leave an indelible imprint on many aspects of their personal lives.


A method to prepare soluble intramolecularly crosslinked copolymers (microgel) by radical copolymerization of vinyl monomer and divinyl compound was developed. Methyl methacrylate (MMA) and p-divinylbenzene (p-DVB) was copolymerized in the presence of a high concentration of transfer agent (CBr4) in benzene. As the ratios of p-DVB and CBr4 to MMA increased, the number average molecular weight decreased and the structure of the microgel became tighter. The soluble polymer was obtained with very high conversion (70—88%). It was confirmed by the characterization of fractionated product that about 50% of the soluble polymers were intramolecularly crosslinked copolymer. The reactivity ratio r (=k13/k12) (M1 = MMA, M2 = p-DVB, M3 = pendant double bond) was not constant throughout the course of all the reactions, and became progressively small with time. rM (k11/k12), however, was always constant (0.27). This can be explained if we assume that the intramolecular crosslink is more rapidly formed than that of the intermolecular and a large amount of loops are formed at the early stage of copolymerization.


This research examines the personal narratives of two contemporary non-native artists living and working on the island of Oahu, Hawaii. Issues related to narratives, power structures, artistic processes, insider/outsider dynamics, Hawaiian culture, island life, surfing, and the researcher's own experiences are woven together to formulate realizations surrounding alternative knowledge systems and the power of multiple or hidden narratives to the practice of art education.


In order to understand the spatial distribution of stress tensors of initial geostress field and to identify its relationship with the cavern group arrangement for hydropower plant site in high geostress region of deep valley,a new method and an operation procedure for obtaining a quantitative and fine numerical initial geostress field based on the coupling of 3D initial geostress calculation model and the structural calculation model containing excavation details were proposed considering the evolution process of river valley,using the space analysis method of stress tensor and the multi-core parallel computing technique. Then,the initial geostress field distribution at Jinping I hydropower station was identified with the method and verified against the field phenomenon of deformation and failure. The underground cavern groups of Jinping I hydropower station were found to be in the stress transitional region near the deep valley with the high geostress levels and the large stress variations and the high initial geostress environment was thus formed. The average principal stress ratio is about 1.9–2.5 and the rock strength-stress ratio is about 1.5–3.0 in this transitional region. Under the high initial 3D geostress,the low strength-stress ratio and the high principal stress ratio,the deformation and the failure and the depth of unloading relaxation of the surrounding rock during the construction of the underground powerhouse cavern groups were found to be larger than the ones of the cavern groups of the same size in other projects. The locations and distributions of the stress induced deformation and failure confirm the reasonability of the initial 3D geostress field obtained and also verify that the above proposed quantitative model of geostress field is correct and feasible. On this basis,a method of layout design for the underground powerhouse cavern groups located in high geostress area was proposed,considering the three-dimensional geostress,the strength to stress ratio and the structure characteristic,etc. The proposed design method reflects the load characteristics of caverns,the structure characteristics and the bearing capacity of surrounding rock. Using the above design method,some principles and procedures are put forward from a qualitative point of view,which includs how to determine the location of the main cavern,the longitudinal axis,the cavern spacing and type,etc.


This paper studies the optimal duration of unemployment insurance (UI) benefits in a basic job search model where a risk neutral UI agency can not monitor the search effort of risk-averse workers. Social assistance payments are taken as exogenous by the unemployment agency which chooses optimally the level of UI benefits, the date of their exhaustion and the level of the financing tax. So, due to possible finite values of the duration of unemployment benefits, the resulting agency's problem brings nonstationarity complexities that are usually deemed intractable in models where utility and search costs functions are nonlinear. We then propose a new strategy, based on the study of the geometric properties of the set of constraints, and explicit formal conditions, with very general utility and search costs functions , for obtaining a zero, positive or infinite optimal duration of UI.


The effect of magnetic force on nonlinear energy harvesting performance is discussed theoretically and experimentally in this paper. A kind of nonlinear magnetic coupled piezoelectric energy harvester (NMPEH) is designed. The bidirectional screw is used to adjust the relative location of the tip magnets and external magnets to get different nonlinear magnetic forces. It is well known that the nonlinear magnetic force will influence the broadband energy harvesting performance. In order to describe the nonlinear dynamic behavior of the NMPEH, harmonic balance method is employed and its excitation test are performed at different accelerations over the range of 5-30Hz. It is also found that the analytical solutions match well with experimental output voltage. The nonlinear energy collector under the influence of symmetric magnetic force studied in this paper can not only reduce the resonance frequency of the system, but also increase the vibration amplitude of the cantilever beam, thus increasing the power obtained from the vibration environment.The effect of magnetic force on nonlinear energy harvesting performance is discussed theoretically and experimentally in this paper.
