The corrosion behaviors of AZ81 magnesium alloy with minor Gd addition have been researched in this paper. The results show that with the minor addition of 0.5-1% Gd, the microstructure of AZ81 magnesium alloy is obviously refined, and the spotted, high-melting point phase Al-Gd intermetallic compounds is found in AZ81 magnesium alloy. The corrosion behaviors of AZ81 alloy decreases obviously with the increase of Gd addition. When the content of Gd is 1%, AZ81 magnesium alloy exhibits the lowest corrosion rate. The corrosion rates of AZ81+Gd magnesium alloy in 3.5% NaCl solution are always higher than those in 0.5%NaCl solution. Introduction Magnesium alloys have been widely used in the fields of automobile manufacturing, aerospace industries and electronic industry, because of their advantages of low density, high specific strength and good recycling potential. Corrosion is another key concern which restricts the wide spread applications of Mg alloys as a structural materials. AZ81 exhibits excellent corrosion resistance due to the high percentage of Al in the Mg-Al series alloy. When the alloy modification takes place to improve its high temperature performance, microstructure changes are inevitable. These additions may introduce various thermally stable intermetallics in the microstructure. Since the corrosion behaviors of AZ81 magnesium alloy is highly sensitive to microstructure, these intermetallics definitely play an important role in the properties [1-5]. On the other hand, poor corrosion resistance of magnesium alloys is a main reason of limiting their further applications. Among the Mg alloys, Mg-Al alloy is the commercially used magnesium alloy for automotive application. In the as-cast AZ series alloys, the addition of rare earth (RE) elements is believed to be a beneficial method to improve their corrosion resistance. Attempts have been made to change the microstructure of Mg-Al alloys by introducing thermally stable intermetallics through addition of special alloying elements and thereby improving its corrosion performance [6-10]. In this work, the influence of minor RE elements Gd additions on the corrosion behaviors of AZ81 Magnesium alloy is studied immersion in 0.5 and 3.5% NaCl solutions. Experimental Pure metallic Mg, Al, Zn and Mg-22 wt.% Gd master alloy are used as raw materials in this work. The researched alloy is designed as AZ81-xGd where x was the content of RE elements Gd, and x=0.5 and 1respectively. These AZ81 alloys are prepared in an induction melting furnace with an Al2O3 crucible under the gas protection of mixed atmosphere of CO2 and SF6. The mold is metallic materials. The as-cast AZ samples are machined and heated for solution treatment at 415 °Cfor 14 h with the protection of MgO powder, and then quenched in hot water. Artificial aging treatments are completed at 225°C for 12 h. Specimens for immersion corrosion tests are cut into coupons, 4-5 mm in thickness and 14-15 mm in diameter, ground with 400 grit water proof abrasive paper and 1200 grit metallographic papers, washed in distilled water, degreased with acetone and immediately immersed in 0.5 wt% and 3.5% NaCl solution. The immersion tests time is 8 hours at 25±2oC with no stirring. The corrosion products are removed by immersion in the distilled water at room temperature for 15 min, International Conference on Materials, Environmental and Biological Engineering (MEBE 2015) © 2015. The authors Published by Atlantis Press 977 and the materials loss is determined by electronic balance. The corrosion rate can be calculated by the following formula: CR=365×24×1000(G0-G)/(ρSt) (1) where CR is the corrosion rate (mm/a), G0 is the weight of metallic samples before immersion corrosion test (g), G is the weight of metallic samples after immersion corrosion test (g), ρ is the density of AZ81 magnesium alloy (1.8g/cm), S is the area of matellic samples (mm), and t is the immersion time of corrosion test and 8h in this experiments. Scanning electron microscopy (SEM) and Olympus optical (OM) are used to characterize the morphologies of corrosion morphologies after immersion corrosion test. Results The microstructure of as-cast AZ81 magnesium alloy with minor Gd addition is shown in Fig. 1. It can be shown that microstructure of as-cast AZ81 magnesium alloy consists of α-Mg solid solution containing Al, Zn elements, and a lot of β-Mg17Al12 phase eutectic. This eutectic is divorced in matrix. Lamellar kind of precipitation can be found in the vicinity of much Mg17Al12 phases, which may be occur from supersaturated eutectic α-Mg solid solution decomposing into lamellar Mg17Al12 phases. Fig.1 The microstructure of as-cast AZ81 magnesium alloy with Gd addition (a) AZ81; (b) AZ81+0.5%Gd; (C) AZ81+1%Gd The microstructure of AZ81 magnesium alloy after solution and aging treatments with minor Gd addition is shown in Fig. 2. It can be seen that the Mg17Al12 phases in AZ81 magnesium alloy after solution and aging treatment are distributed in the grain interior and at the grain boundaries and have granular and rod-like morphologies (see Fig. 2a). With the addition of 0.5-1% Gd, the microstructure of AZ81 magnesium alloy is remarkably refined, and the spotted, high-melting point phase Al-Gd intermetallic compounds is found in the alloy. A small amount of Mg17Al12 phase remains in AZ81+0.5% Gd alloy (see Fig. 2b). With the increase in Gd content, a large number of blocky Al-Gd intermetallic compounds are formed and tended to segregation (Fig. 2c). The possibility of forming metallic compounds should be predicted by the electronegativity difference between two elements and the solidification reaction kinetics. The larger the electronegativity differences between two alloy elements, the stronger the higher possibility of forming metallic compounds. The electronegativity difference between Al and Gd is higher than that between Al and Mg. This indicates that Al–Gd compounds can be formed more easily than Mg17Al12 compounds, and so Mg17Al12 phases decrease with the addition of Gd. Blocky Al–Gd compounds formed in the microstructure.

Bone implants are long term solutions for bone loss. Currently, two issues have been identified as reducing the long term stability of bone implants. The first issue is stiffness mismatch between the implant and the surrounding bony structure. The current materials used for manufacturing bone implants are much stiffer than the surrounding host bone. The second issue concerns bone-implant integration; the fact is that the bone needs an appropriate surface on which to attach and accept or deliver a load. Additive manufacturing techniques using Nitinol may provide the ability to fabricate bone implants with predetermined pore size and stiffness. This work brings the concept of stiffness tailoring to reality, taking advantage of additive manufacturing technique to fabricate engineering porosity to modify the stiffness. Based on the simulation and test results, it is shown that implants can be made with the stiffness in the range of the stiffness of the bone. The same capabilities can be used to affect a rough surface onto which bone is more likely to attach.Copyright © 2014 by ASME

The relevance of the issue under investigation is conditioned by an increase of the ecological burden on the environment due to the continuous increase of plastic waste, a significant proportion of polypropylene. One solution to this problem is the involvement of recycled polypropylene to obtain plastic products based on composites filled with rice husk. It makes it possible to reduce the prime cost of finished products, regulate their physical and mechanical properties, and reduce the volume of difficult-to-decompose synthetic polymers that end up in waste. The key property of polypropylene, which changes during its filling with rice husk, is moisture absorption, which contributes to a change in the strength characteristics of the polymer composite and accelerates its aging under the influence of environmental factors. In this regard, this research aims to identify the patterns of the influence of absorbed moisture and natural aging on the physical and mechanical properties of polymer composites based on recycled polypropylene filled with rice husk. The leading approach to the study of this issue is laboratory tests on the saturation of polymer composites with water of different temperatures and duration of exposure and testing materials during long-term natural aging under the influence of environmental factors. The key factor characterizing the change in the physical and mechanical properties of materials, in this case, is the elasticity modulus, elongation, and tensile stress at the break during stretching of the prototypes. The materials of the paper are of practical value for the processing of secondary thermoplastic polymers, as well as the development of biodegradable polymer composites.

The compiler automatically generated from action-semantics directed compiler generators first translates a source program to its action denotation, and then to a target code. To improve the efficiency of the target code, it is essential to transform the action denotation into the proper one leading to a better target code. In this paper, an automatic action transformation based on partial evaluation is presented, along with methodology to analyze action semantics equations, allowing necessary analyses to be performed at compiler-generation time before source programs are given.


An overemphasis on English competence in the age of global economy is causing excessive enthusiasm for English learning in Korea. This "fever" fuels an abnormal increase of private education, which in turn results in a malfunction of public education. The excessive enthusiasm for English has also affected the National Curriculum: It has recently set a purely practical goal for English education for the nation, ignoring its important function of general education. This article argues that any foreign language education should include the purpose of broadening the students' horizons, and criticizes the present bias of English education toward vocational training. It contends that the National Curriculum for English subject should be a balanced syllabus for general education as well as for practical skills. Three goal areas are suggested for a balanced curriculum: Communications, Comparative Languages and Comparative Cultures. Each of these closely interrelated areas has the dual purpose of teaching knowledge and skills. Knowledge-and-skills goals are likely to motivate the students to learn English as a Foreign Language more effectively than the single goal of learning English for practical skills. Finally, regarding the supply of fluent English users needed for global business and other professional fields, universities and international companies could provide intensive programs that focus on English for Specific Purposes for those secondary school graduates who want to engage in such fields.


Long-term,effective measurements of 222 Rn progeny are often based on measurements of the 222 Rn concentration.Assuming equilibrium between the 222 Rn and its progeny,the 222 Rn progeny concentration can be found by measuring the 222Rn gas concentration. However,this method is limited for the measurements of the 220 Rn progeny concentration because the 220 Rn progeny concentrations are not uniform or vary with time.The proportions between 220 Rn and its progeny are only valid after a long time range.This article summarizes a broad range of research data from laboratory and field measurements to analyze the indoor distribution of 220 Rn and its progeny and give a relationship between the equilibrium factor and the distance from the wall,and validates the applicability of using equilibrium factors between 220 Rn and its progeny to evaluate 220 Rn progeny concentrations at long time ranges.


Salinity is one of the most abiotic factors which adversely affected the crop yield due to limits the growth and production of crop in arid and semi arid regions in the world. Seedling establishment is a most critical stage that determined the crop production at later stages, thus it must necessity to study the effect of salt stress on germination and early seedling parameters. Present investigation aimed to assess the effect of salt stress on germination and early seedling parameters of fenugreek. Fenugreek (Trigonella foenum-graecum L.) is a winter season seed spices crop, commonly known as Methi and moderately tolerant to salinity. We took ten genotypes of fenugreek grown under five salinity levels viz., 0.0, 40, 80, 120 and 160 mM NaCl salinity induced by supplementing 0.0, 584.4, 1168.8, 1753.2 and 2337.6 mg NaCl in 250 ml double distilled water, respectively. Results showed that the mean value was found maximum in the control and minimum at higher salinity level for most of characters. Higher reduction was found at higher salinity levels for most of the characters viz., plumule length, radicle length, seedling length, plumule to radicle length ratio, plumule fresh weight, radicle fresh weight, plumule dry weight, radicle dry weight and seedling vigour index but lower reduction in germination percentage. Based upon the rank totals of a genotype over different salinity levels S1, S2, S3 and S4 (Sm) and characters, the genotype RMt-303 was found to be most desirable followed by UM-385, RMt-143 and RMt-305. The comparison between mean of different genotypes in control (S0) versus Sm (mean of S1, S2, S3 and S4) for each character also revealed that overall mean was highest in control as compared to the overall mean of salinity levels for all the characters.

Abstract This article presents new data from a number of Germanic languages concerning the agreement patterns found in copular clauses that contain two nominais; in both clauses with specificational readings (such as The problem is your parents) and those with what are here termed readings of assumed identity (such as If I were you or In my dream I was you). It is argued that the specificational sentences involve asymmetric equative structures where one nominal is interpreted as in a concealed question, and that the cross-linguistic differences in agreement patterns found in the languages considered follow from the copula lexicalizing either Tense or a lower head.


Background: An acute kidney injury (AKI) is a recognized complication in patients with ST elevation
myocardial infarction (STEMI) by several mechanisms and it adversely affects morbidity and mortality on
long-term bases (1, 2, and 3). Few studies have investigated which patients with STEMI are at risk of developing
AKI (6), and this study is aiming to do this assessment.
Patients and Methods: We enrolled patients with STEMI who were admitted to the CCU. KDIGO
definitions was utilized to search for development of AKI in these patients throughout their stay in the
CCU (their baseline serum creatinine was measured and traced daily thereafter; and their urine output was
monitored). Common epidemiological and some relevant medical parameters were recorded for all patients.
Results and conclusion: low baseline systolic blood pressure, ejection fraction % and estimated glomerular
filtration rate (eGFR); in addition to use of diuretics; are the major risk factors for the development of AKI
in the setting of STEMI.


This paper presents preliminary results of a semi-automatic methodology to extract three parameters of a dynamic model of speech rhythm. The model attempts to analyze the production of rhythm as a system of coupled oscillators which represent syllabicity and phrase stress as levels of temporal organization. The estimated parameters are the syllabic oscillator entrainment rate (alpha), the syllabic oscillator decay rate (beta), and the coupling strength between the oscillators (w0). The methodology involves finding the  combination that minimizes the distance between natural duration contours and simulated contours generated using several combinations of the parameters. The distance between natural and model-generated contours was measured in two ways by comparing: (1) plain or overt syllable to syllable duration and (2) relative change along both contours.We applied this methodology to read speech produced by five speakers of the state of Ceará (CE) and eight speakers of the state of São Paulo (SP). Mean w0 and alpha values are compatible with the view that Brazilian Portuguese is a mixed-rhythm language. Results from two bayesian hierarchical regression models do not suggest a difference between SP and CE speakers, but indicate a difference between the two methods, with the relative change method generating lower alpha values and higher w0 values, and the reverse for the plain duration method.


A scheme for the entanglement swapping of entangled states with continuous variable is presented, in which the bipartite maximally entangled coherent state serves as the quantum channel.With the help of the idea of teleportation,using beam splitter and phase-shifter,entanglement swapping of tripartite entangled coherent state can be realized.In this scheme,the entanglement swapping is failure only for one measurement process.The failure probability is very small.The detail results show that the probability and the minimum of total average fidelity for successful swapping an arbitrary tripartite entangled coherent state is nearly 1 when the mean number of photons is larger than 2.


Pointlike plasma bullets have been reported in atmospheric plasma jets below 50 kHz. This paper presents 10-ns images of both pointlike and striplike plasma bullets generated at frequencies between 80 and 394 kHz. The striplike plasma bullets are always present, whereas the pointlike ones are suppressed at sufficiently high frequencies. Abel-converted images show that the pointlike plasma bullets have a long tail of 4.5 cm extended to the anode region.

In the Anthropocene, the interplay between human and natural systems has become deeper and more complex than ever. This has increased the normative urgency of sustainability integration, exposing two main gaps. First, a knowledge gap between the new context and the conceptual frameworks available to understand its impact on how we perceive and deal with sustainability integration as a response to those changes. Second, an institutional gap between the structure and aims of current institutions – which include the Sustainable Development Goals - and the demands and challenges of the new Anthropocenic context. This thesis begins by developing a conceptual framework to investigate whether and how change towards sustainability integration is happening at the ideational, normative, and institutional level. It then puts the framework to the test and addresses three main research questions. First, how can we study and explain which models of sustainability integration are prevalent in the Anthropocene? Second, which models of sustainability integration are prevalent and why? Third, how do institutions such as the SDGs influence the prevalence of different models of sustainability integration? The results show a generalised prevalence of the balanced model of integration over the ecocentric model. The ambiguous relationship observed between the SDGs and different models of integration is also likely to affect their ability to fulfil their ambitious claims.

Each day, thousands of youth experience bullying and as many of 70% of all youth report having experienced bullying, either directly or indirectly (Cantor, 2005). For Gay, Lesbian, Bi-sexual, Transgender and Questioning (LGBTQ) youth, the chances of experiencing bullying are much higher than for youth in the general population (Russell, Horn, Kosciw, & Saewyc, 2010). Although many youth serving organizations have begun to address the issue of bullying with bullying prevention programs, there is a deficit of information and a lack of inclusion of prevention efforts that specifically address LGBTQ youth. This article address the role of youth organizations in creating safe and inclusive environments for all youth, with specific attention paid to resources and strategies for inclusive environments for LGBTQ youth.

The existing nonuniformity correction methods generally have the defects of image blur, artifacts, image over-smoothing, and nonuniform residuals. It is difficult for these methods to meet the requirements of image enhancement in various complex application scenarios. In particular, when these methods are applied to dim small target images, they may remove dim small targets as noise points due to the image over-smoothing. This paper draws on the idea of a residual network and proposes a two-stage learning network based on the imaging mechanism of an infrared line-scan system. We adopt a multi-scale feature extraction unit and design a gain correction sub-network and an offset correction sub-network, respectively. Then, we pre-train the two sub-networks independently. Finally, we cascade the two sub-networks into a two-stage network and train it. The experimental results show that the PSNR gain of our method can reach more than 15 dB, and it can achieve excellent performance in different backgrounds and different intensities of nonuniform noise. Moreover, our method can avoid losing texture details or dim small targets after effectively removing nonuniform noise.


Using the resonance-enhanced multiphoton-ionization technique, we have identified the n $^{2}\mathrm{P}_{1/2}$(7\ensuremath{\le}n\ensuremath{\le}20), $^{2}\mathrm{P}_{3/2}$(7\ensuremath{\le}n\ensuremath{\le}23), and $^{2}\mathrm{F}_{5/2,7/2}$(5\ensuremath{\le}n\ensuremath{\le}21) Rydberg states following photodissociation of TlI. The $^{2}\mathrm{P}_{1/2,3/2}$ spin-orbit splitting can be resolved and well compared to its theoretical counterpart with an accuracy of \ifmmode\pm\else\textpm\fi{}3.5%. In terms of photoionization-cross-section prediction, we have also satisfactorily interpreted the discrepancy for the relative ionization intensity, via the respective intermediate $^{2}\mathrm{P}_{3/2}$ and $^{2}\mathrm{P}_{1/2}$(n\ensuremath{\le}11) doublets, from their statistical weight.

In order to decrease the fuel consumption, an important way is increasing the bypass ratio of the turbofan engine. Unfortunately, as the bypass ratio becoming higher, turbofan would suffer Spool-Speed Mismatching Issue (SSMI). This paper proposed a design innovation of high bypass ratio turbofan, which comprised an additional Tip-Driving Fan (TDF), aiming to solve the SSMI problem. At first, this paper presented TDF turbofan concept which comprised a high bypass ratio fan and an air-turbine at the tip of the fan. Then the advantages of TDF and its potential were analyzed, based on the discussion of the SSMI and typical designs to solve it, for instance the Geared Turbofan. Secondly, thermodynamic and aerodynamic analyses for TDF were performed and some basic equations and principles were discussed, such as: energy loss, Load factors with different spool rotating speed, matched velocity setting of fan and air-turbine. Finally, the TDF blades, the key components of this new design was preliminarydesigned and the flow field was numerically simulated. The parameter research showed that a prototype turbofan which applied the TDF obtained higher bypass ratio, 25, than its original value 5.3.


Corrosion is the leading cause of failures of subsea pipelines in the U.S. Gulf of Mexico. Third-party incidents, storms, and mud slides are additional principal causes of offshore pipeline failures. These are among the major conclusions of an analysis of 20-year pipeline-failure data compiled by the Minerals Management Service, U.S. Department of Interior. For small size lines, the failures due to external corrosion were more frequent during the period studied than internal corrosion. In medium and large-size lines, failures due to internal corrosion were more frequent than those due to external corrosion. Also, the majority of corrosion failures occurred on or near the platform and among the small-size pipelines. The motivation for the study described in this article was to perform a more in-depth evaluation of the pipeline failure data for the Gulf of Mexico than reported earlier, using an extended data base for the period 1967-87, and to compare the results with those reported earlier. The study results presented in this article provide an improved basis for an assessment of the safety of pipelines and for further improvements to current pipeline design, inspection, maintenance, and construction procedures.


Between March, 1986 and September, 1989, nonvalved conduits were used in 9 patients, ages ranging between five and seventeen years. Cardiac pathologies were atrioventricular and ventriculoarterial discordance with ventricular septal defects (VSD) and pulmonary stenoses (PS) in 5, transposition of great arteries (TGA) + VSD + PS in 1, and double-outlet left ventricle (DOLV) + VSD + PS in 3. Pulmonary obstruction was valvular in 1, valvular and infundibular in 7. There was 1 patient with pulmonary atresia. Valveless conduits 16-22 mm in diameter were used between the pulmonic ventricle and the pulmonary artery. All patients recovered from operation and remained well, except 1 with DOLV who died with severe arrhythmias the third postoperative day. During the mean follow-up of 32 ± 11.8 months 1 patient died of acute cardiac failure in the ninth month and all other patients were asymptomatic without needing reoperations. These results have been encouraging for the use of nonvalved conduits in complex congenital cardiac anomalies.


Introduction: Chronic obstructive pulmonary disease is one of the leading causes of death. Restless Legs Syndrome is associated with many systemic diseases. RLS is found in many patients with COPD. There is paucity of data on this topic from India.Aim: The aim is to find the prevalence of RLS in COPD patients and its distribution in study population with respect to various demographic and clinical characteristics. Correlation between severity of RLS and COPD severity was also aimed to be evaluated.Setting and design:Prospective, observational study conducted in a tertiary care institute over a period of 12 months. Materials and methods:After fulfilling the inclusion criteria the patients were categorised according to the severity of COPD using the GOLD guidelines. Diagnosis and severity of RLS was evaluated using IRLSSG criteria. Prevalence and association of RLS with COPD and its demographic and clinical characteristics was evaluated. Results:A total of 294 patients were taken which included 229(77.9%) males and 65 females (22.1%).Mean age was 62.05 ± 10.32 years. Smoking was a more common risk factor among the patients (85.7%). 110 patients were diagnosed with RLS. A statistical significant association was found between duration of COPD and RLS (p value =0.001) and also between severity of COPD and RLS (p value=0.001). A significant positive correlation (r=0.395, p value= 0.001) between severity of COPD and RLS. Forty two (87.5%) patients with definite RLS had stage D COPD. Degree of obstruction of airways showed a statistical significant association with prevalence of RLS (p value=0.001). Conclusion: RLS showed increased prevalence in COPD patients making it crucial to screen all the COPD patients for symptoms of RLS and if required to treat the symptoms, thus improving the quality of life.


Background Lesion scores on procurement donor biopsies are commonly used to guide organ utilization. However, frozen sections present challenges for histological scoring, leading to inter- and intra-observer variability and inappropriate discard. Methods We constructed deep-learning based models to recognize kidney tissue compartments in H&E stained sections from procurement biopsies performed at 583 hospitals nationwide in year 2011-2020. The models were trained and tested respectively on 11473 and 3986 images sliced from 100 slides. We then extracted whole-slide abnormality features from 2431 kidneys, and correlated with pathologists' scores and transplant outcomes. Finally, a Kidney Donor Quality Score (KDQS) incorporating digital features and the Kidney Donor Profile Index (KDPI) was derived and used in combination with recipient demographic and peri-transplant characteristics to predict graft loss or assist organ utilization. Results Our model accurately identified 96% and 91% of normal/sclerotic glomeruli respectively; 94% of arteries/arterial intimal fibrosis regions; 90% of tubules. Three whole-slide features (Sclerotic Glomeruli%, Arterial Intimal Fibrosis%, and Interstitial Fibrosis%) demonstrated strong correlations with corresponding pathologists' scores (n=2431), but had superior associations with post-transplant eGFR (n=2033) and graft loss (n=1560). The combination of KDQS and other factors predicted 1- and 4-year graft loss (discovery: n=520, validation: n=1040). Finally, by matching 398 discarded kidneys due to "biopsy findings" to transplanted population, the matched transplants from discarded KDQS<4 group (110/398, 27.6%) showed similar graft survival rate to unmatched transplanted kidneys (2-, 5-year survival rate: 97%, 86%). KDQS ≥ 7 (37/398, 9.3%) and 1-year survival model score ≥ 0.55 were determined to identify possible discards (PPV=0.92). Conclusion This deep-learning based approach provides automatic and reliable pathological assessment of procurement kidney biopsies, which could facilitate graft loss risk stratification and organ utilization. Translational Statement This deep-learning based approach provides rapid but more objective, sensitive and reliable assessment of deceased-donor kidneys before transplantation, and improves the prognostic value of procurement biopsies, thus could potentially reduce inappropriate discard and stratify patients needing monitoring or preventative measures after transplantation. The pipeline can be integrated into various types of scanners and conveniently generates report after slide scanning. Such report can be used in conjunction with pathologists' report or independently for centers lacking renal pathologists.


Background: Although the number of colorectal operations performed laparoscopically has increased, it has not yet surpassed the number of laparotomies. The purpose of this single centre study was to determine, using various parameters and following well-structured and standardized surgical and post-operative procedures the safety and clinical outcomes of laparoscopic colorectal resections performed in a regional hospital by a team of surgeons supervised by a specialized in laparoscopic colorectal surgery. Through this process, it was given the opportunity to evaluate the impact of the learning curve by comparing their performance. Methods: From 2012 to 2021, a total of 234 patients with pathology in the colon and rectum underwent laparoscopic colorectal resection. Patients' case records and histopathology reports were examined for predefined parameters, statistically analysed and compared.Results: The type of operation had a significant effect on operative time (p<0.001). When the duration of operation was correlated to the number of hospitalization days, a significant positive association was found (r=0.173, p=0.012). The patient's age showed to affect operative time in a proportional way (p=0.004), while the reverse is true for the number of days after 1st surgery (p<0.001). A reduction in operative times was observed for both the specialized and non-specialized surgeons (r=-0.315, p<0.001, rs=-0.324, p<0.001), with a larger decline for specialized surgeon (r=-0.322, p<0.001, rs=-0.360, p<0.001). Conclusions: Taking into consideration all the parameters, it is our belief that through the framework we have implemented, any surgeon can complete uneventfully the learning curve of laparoscopic colorectal surgery, even in a regional hospital.


The Covid-19 epidemic has made Malaysian consumers between the ages of 19 and 30 were highly dependent on social media. This is due to the fact that all activities, including employment and education necessities, are conducted online on social media platforms like Facebook and WhatsApp. This research propose that the negative or positive use of social media are depending on the personality of the user. Neuroticism, Extraversion, Openness, Conscientiousness, and Agreeableness are the five primary personalities according to The Big Five Personality Theory. This study examines the use of social media during the Covid-19 pandemic. There were 200 respondents who voluntarily engaged in this survey. The study found that Neuroticism increased by 0.814% based on time spent on social media, whereas Extraversion increased by 0.905%. In addition, the survey found that male respondents have a higher Neuroticism score (m=5.378) than female respondents (m=4.639), and that male respondents utilise social media more (m=5.781) than female respondents (m=5.574). To conclude, high institutions such as the government, universities, teachers, and students can benefit from this research regarding the negative health effects of excessive social media use.

Defects in sandwich structures are often inevitable and can originate both from manufacture and use. An important defect type is debonding, i.e. areas with weak or no adhesion between skin and core. In a sandwich structure debondings can arise in production when an area between skin and core has not been wetted properly resulting in a lack of adhesion. In use, damages from loads e.g. impact might result in formation of a debond crack. With debonds present the structure might fail under loads significantly lower than those for the intact sandwich structure. In order to improve the damage tolerance of sandwich structures an increase in the toughness between skin and core is necessary [1]. It is believed that the microstructure of the interface between skin and core can have a large effect on the fracture toughness. It has been shown that the presence of a mat with random oriented and loosely packed fibers between the core and the laminate facilitates the formation of large scale fiber bridging, resulting in a significant increase in crack resistance [2]. The formation of large scale fiber bridging results in a fracture process zone with length several times the skin height. To characterize the crack growth resistance the J integral is deployed since it is valid for handling fracture with large fracture process zone. By analytical derivation the J integral is determined for the special sandwich specimens used in the tests [3]. The aim of the current work is to establish a more fundamental understanding of sandwich fracture and mechanisms taking place during fracture. Several conditions have an influence on the fracture mechanisms and nominal fracture toughness e.g. mode mixity of the loading, skin lay-up, resin type and core density. In the experimental part of this study we measure the fracture toughness of the skin/core interfaces for one material combination by loading specimens under different mode mixities. Observations during experiments are used to identify mechanisms related with variation in fracture toughness for the different mode mixities. Specimens are manufactured by an industrial partner, with materials and thicknesses similar to those used in structural components. The sandwich consists of 2.5 mm thick glassfiber/polyester skins and 20 mm thick PVC foam core with density 80 kg/m. A teflon film strip is placed between skin and core during manufacture to have a well defined start crack. The build-up configuration of the skins is (0/90, Unifilo®, ±45, CSM), where the CSM (chopped strand mat) laminae is located next to the core. The Unifilo and CSM laminaes consist of continuous fibers oriented randomly. The biaxial mat (0/90 and ±45) is 0.7 mm thick and has an area density of 600 g/m. The Unifilo and CSM laminaes are 0.7 mm and 0.4 mm thick respectively and have an area density of 450 g/m and 300 g/m respectively. The overall dimensions of the sandwich specimens are 25 mm thick, 30 mm wide and 450 mm in length. The test method is based on loading the sandwich specimen by uneven bending moments, see Figure 1. By varying the moments the ratio between tangential and normal crack opening displacement can be varied in the full mode mixity range. The loading by moments has the advantage that stable crack growth is accommodated because the J integral value is independent of the crack length. The moments are applied by vertical forces acting on two horizontal arms attached to the top of the specimen. The forces are applied by a roller/wire system mounted in a tensile test machine. Figure 1. Test specimen loaded by uneven bending moments As the load exceeds a critical value crack growth is initiated and the right skin separates from the core. Because of the thin skin and increasing crack length large rotations occur, which is critical for the accuracy of the test. The rotations are reduced by adhering a 2 mm thick aluminium strip to the right skin. The stiffening of the skin is taken into account in the analytical derivation of the J integral. Stiffening of the skin furthermore has an effect on the fracture behaviour if mechanisms as fiber bridging occur because the reduced rotation elongates the fracture process zone (see Figure 2). Figure 2. Failure process zone with and without stiffening of the skin Hereby the spatial material variation is reduced since the fracture process takes place over a larger area and a more homogenous behaviour is measured.


Novel alternatives to the conventional single crystal diamond Schottky metal-intrinsic-p + (m-i-p + ) diode is presented in this work. The conduction mechanism of the device is analysed and structural modifications to enhance its performance are proposed. The periodic inclusion of highly p + doped thin δ-layers and p + spots in the intrinsic voltage blocking layer of the diode drastically improves the forward performance of these devices enhancing the forward current of the device by a factor of 10 - 17 with a maximum forward current density of 40 A/cm 2 for a 2 kV device.


The curtain coating process has been used for years in certain industries such as photo film and PSA. In papermaking, curtain coating is commonly used for specialty papers such as thermal paper, ink jet papers and carbonless paper. This process offers interesting perspectives for printing and writing coated paper grades. But it is very demanding and its requirents are different from the traditional ones, regarding coating colour components and preparation. Successful curtain coating can be associated with modification of surface tension and extensional properties of coating colours. The measurement of dynamic surface tension coating colours at short life time becomes therefore necessary to evaluate the efficiency of surfactants.


The Fourier transform infrared spectra of individual conodonts with various CAI values indicate definite changes in conodont francolite during diagenesis. Steady decarbonation can be observed in the increasing intensity of the band with the wavenumber 2340 an-1, which is assigned to trapped molecular CO2. Carbon dioxide originates from decomposing CO2-3-ions occupying the B-site in francolite. Furthermore, the intensity of the water-deformation band at 1644 cm-1 decreases with higher CAI values. These changes of intensity can be quantified by calculating the maximum extinction (Emax) for the corresponding absorption maxima and correlated with the CAI. Unaltered conodonts have a relative variable water 'content' and very little CO2. Up to a CAI value of 4 conodont francolite continuously expells water and carbon dioxide is trapped. Conodonts with CAI = 5 have similar water 'contents' to CAI = 4 conodonts, but decarbonation continues to take place during this stage of diagenesis.


Our previous quantum‐mechanical calculations, by an all‐valence‐electrons method (PCILO) taking into account simultaneously the σ and π electrons of the system, on the conformation energy maps of the glycyl and alanyl residues are extended to the evaluation of these maps and of the stereochemical rotational states of the aromatic residues, phenylalanyl, tyrosyl, histidyl, and tryptophanyl in dipeptides. Calculations on model compounds are used for the predetermination of the side‐chain rotational angles χ1 and χ2 which are then used as selected parameters for the evaluation of the conformational energy maps as function of the backbone rotational angles Φ and ψ. The theory predicts that the most stable conformation for these aromatic residues should occur in the same region, around Φ = 200, ψ = 140°, in which it was predicted to occur for the glycyl and alanyl residues and which was completely overlooked by most of the previous "empirical" computations. Recent experimental work by a group of Russian authors using NMR and infrared techniques seems to confirm the theoretical result for the alanyl and phenylalanyl residues. The paper indicates also the secondary local minima which appear for the different residues. The theoretically allowed general conformational area for the four aromatic residues, within the reasonable value of 5 kcal/mole above the deepest minimum, is somewhat larger than the similar area allowed by the "hard sphere" empirical calculations. Practically all available representative experimental points from the study of small molecules and of the proteins lysozyme and myoglobin fall within the allowed area, the agreement being better with the results of the quantum mechanical calculations than with those of the "hard sphere" approximation. The values of the side‐chain rotational angles χ1 and χ2 and of their allowed combinations agree less satisfactorily with experiment, the experimentally observed combinations being more varied than the theoretically allowed ones. These last ones having, however, been predetermined on studies with model compounds, this situation is not astonishing. It is proposed to refine these results by a minimization with respect to the four parameters Φ, ψ, χ1, and χ2 involved.


This paper presents a 3D mathematical model for transfer and transform of water contaminants in reservoir, describes the discrete methods and the compute process of using an element-free collocation method. By these models and methods, the water quality conditions of Miyun reservoir area, the quantified description of three dimensions concerning the distribution and change of diversified contaminants are obtained within the assigned time. The distributions of total nitrogen and total phosphorus of the reservoir area in 2003, 2004 and 2005 are simulated and forecasted by the boundary conditions in 2003, so the main development trend is shown. It is found through calculation that: The contribution of the bed mud with regard to total phosphorus is comparatively marked. On the whole, the influence factor of the bed mud in the reservoir area and other comprehensive factors to total phosphorus are quite great. The influence of the living things or other function in the surface water of the Chaohe River valley in the east of the reservoir on the total phosphorus is comparatively conspicuous. Within the reservoir area in spring, summer and autumn, the concentration distribution of total nitrogen is basically in the trend of a slow progressive decrease, but the concentration of total phosphorus increases progressively. It is just contrary in autumn, winter and spring, the concentration of total nitrogen increases and the concentration of total phosphorus decreases. On the whole of the year's development, the total nitrogen is basically in a steady state, and the total phosphorus is in the increasing trend with years, but the kind of the trend is not conspicuous.


Solving the Hamilton-Jacobi-Isaacs (HJI) equation, commonly used in H∞ optimal control, is often referred to as a two-player differential game where one player tries to minimize the cost function while the other tries to maximize it. In this paper, the HJI equation is formulated online and forward-in-time using a novel single online approximator (SOLA)-based scheme to achieve optimal regulation and tracking control of affine nonlinear continuous-time systems. The SOLA-based adaptive approach is designed to learn the infinite horizon HJI equation, the corresponding optimal control input, and the worst case disturbance. A novel parameter tuning algorithm is derived which not only achieves the optimal cost function, control input, and the disturbance, but also ensures the system states remain bounded during the online learning. Lyapunov methods are used to show that all signals are uniformly ultimately bounded (UUB) while ensuring the approximated signals approach their optimal values with small bounded error. In the absence of OLA reconstruction errors, asymptotic convergence to the optimal signals is demonstrated, and simulation results illustrate the effectiveness of the approach.


This study has investigated the box-section beam under torsion. Eight beams made of Dendrocalamus asper were laminated and bonded with 268g/m 2 of urea formaldehyde. The beams were then cool-pressed by 2MPa for 4 hours. The section size of the beams are 80mm, 120mm, and 160mm with 15mm, 20mm, and 25mm of thickness. The results showed that the maximum shear stress occured in the range of 4.39Mpa to 10.13 MPa with a mean of 6.50 MPa. Shear modulus of beam occured in the range of 690.68MPa to 1072.28 MPa with the mean of

Abstract It is clear that changes in [Ca2+]i due to Ins(1,4,5)P 3 release is one of the earliest events observed in lymphocytes when they are activated. Although its role as a second messenger and regulator of some early events involved in lymphocytes activation is well established, the involvement of Ca2+ in downstream events during immune response remains to be determined. There is also indirect evidence to suggest that increase in [Ca2+]i may play a role in processes involved in intrathymic development to established self tolerance. It is likely that more progress will be made in the coming years to provide answers to some of these issues.


The Franklinian margin composite tectono-sedimentary element (CTSE) in North Greenland is dominated by Neoproterozoic - lowermost Devonian sedimentary strata that include early syn-rift through passive margin TSEs of mixed carbonate and siliciclastic facies. The sedimentary successions are well exposed in much of northern Greenland, but locally were strongly affected by the Ellesmerian Orogeny, resulting in a fold and thrust belt that deformed the northernmost exposures. An exposed palaeo-oilfield attests to the petroleum potential of the basin. Several formations have good source potential and several others have good reservoir properties. Palaeo-heat flow indicators show that temperatures increase to the north, where much of the basin is over-mature. Because of the remoteness of the area and the restricted locations where petroleum potential is likely to remain, the basin is not currently a target for exploration.


The difficulties faced by EFL/ESL students when asked to pro duce a piece of writing are often due to an inadequate understanding of how texts are organized. To facilitate effective writing therefore, teachers have to familiarize students with the rhetorical structures which are an important part of the meanings of texts. This article focuses on an important type of written discourse, the argumentive essay, and proposes a preliminary descriptive frame work of its rhetorical structure. Presenting research results, the author shows that a "categories analysis" can clarify the structure of written texts and provide pedagogically useful materials. A case is argued for the importance of explicit linguistic knowledge in deve loping writing skills and some implications for teaching strategies are drawn.


It has been widely believed that the exchange rate depreciation of local currency results in an increase of domestic inflation. This notion is based on the assumption that depreciation of local currency will give the economy's competiveness a boost in international trade which in turn will increase overall demand and inflation. Additionally, some prices set on the international market will increase directly in terms of local currency after such a depreciation. The purpose of this article is to verify the hypothesis that local currency depreciation has a negative impact on inflation in Poland through the credit channel, i.e. foreign currency denominated loans. In Poland a significant open foreign exchange position is related to households' exposure to foreign currency loans (particularly Swiss franc mortgages). Taking this into consideration the depreciation of the Polish zloty results in lower demand from households indebted in foreign currencies and imbalances in the banking system. The hypothesis was verified through observation of the dependence between the share of foreign currency loans and core inflation in 2015-2016 for Poland and comparable economies. Observation of data in most of the countries confirms the hypothesis that the higher the share of foreign currency loans, the lower the core inflation (in the environment of local currency weakness). The article enriches economic science with an analysis of an open foreign exchange market position and its impact on inflation as potential tool for government and central bank policy. An analysis of the entire open foreign exchange position of the economy, including an analysis of the international trade channel could provide important findings in the area of optimal portfolio building in the foreign exchange market and can have possible regulatory implications. Introduction Inflation in Poland from January 2013 until January 2017 was below the inflation target set by Narodowy Bank Polski (NBP – the Polish central bank). Low inflation/deflation was believed to be influenced by global factors – a low inflation environment in the world, subdued economic growth and lower raw materials prices. Concurrently, the Polish zloty in the course of recent years was relatively weak, particularly in relation to developed countries' currencies. According to mainstream economics' theory, depreciation of local currency increases domestic inflation. This is the result of a direct increase in import prices and an aggregated demand increase for domestic goods and services stemming from a competiveness boost. However, the impact of local currency depreciation on inflation may be different when the economy has a significant position in the foreign exchange market, for example due to loans denominated in foreign currencies. The purpose of this article is to verify the hypothesis that local currency depreciation has a negative impact on inflation in Poland through the credit channel, i.e. foreign currency denominated loans. 56 EXCHANGE RATE AND INFLATION IN POLAND. THE IMPACT OF FOREIGN EXCHANGE LOANS Marcin Pieńkowski The correlation between the share of foreign currency loans and core inflation was observed in 2015–2016 for Poland, comparable economies (non-euro members of the European Union located in Central Europe) and the euro area. This observation will be used to verify the hypothesis. The chosen time period followed the decision of the Swiss National Bank to resign from defending the 1.2 level of the Swiss franc against the euro, after which the Swiss franc strengthened considerably. The article enriches economic science with a consideration of the open foreign exchange market position and its impact on inflation as a potential tool for government and central bank policy. Apart from the introduction, the article consists of: a literature overview concerning the exchange rate pass-through effect on inflation, a describing potential impact of foreign currency loans on inflation with example of Poland, an observation of comparable countries data and the conclusion.

Abstract: On the basis of generally surveying the ecological, social and economic conditions and water budget theory, in this paper the water consumptions of all the industries in Wuqi County, Shaanxi Province in 2015 are predicted, and the carrying capacity of water resources in the county in the future is assessed by calculating the index of water resources balance. The results show that, according to the current industrial structure and development trend, the water consumptions of agriculture, animal husbandry, woodlands and grasslands, industry, and general life in Wuqi County in 2015 will be 2.954×107 m3, 1.2×105 m3, 1.1063×108m3, 7.38×106 m3 and 1.96×106 m3 respectively, the total water consumption will be 1.4963×108m3 and occupy 78.7% of the total volume of available water resources, and the water demands will be basically satisfied. Based on the consideration of maintaining vegetation growth and avoiding occurrence of dry soil layer, the minimum ecological water consumption of woodlands will be 2.8612×108m3, the index of water resources balance will be-1.5, and the carrying capacity of water resources will not be able to satisfy the scale of ecological and economic development in the future. The proportion of water consumptions of forestry, agriculture and industry will occupy 98.62% of the total water consumption, which reveals that the shortage of water resources in the county will mainly occur in the ecological regeneration and the economic development under the conditions of extensively regenerating vegetation in the Loess Plateau and energetically developing economy in northwest China. Therefore, the purpose of researching the carrying capacity of water resources in the county should be based on the consideration of solving the contradiction between the ecological environment regeneration and economic development so as to rationally redistribute water resources and achieve the maximum ecological benefits and economic returns.


COMPETENCIES AND BEHAVIORAL PROBLEMS IN TRANSYLVANIAN PREADOLESCENTS Evelin Petric, PhD Student1 Susana Farcas, PhD Student1 Anna Veres, PhD Student1 Dr. Stefan Szamosközi, Prof.2 1 Babeș-Bolyai University, Evidence-based assessment and psychological interventions-, Romania 2 Babeș-Bolyai University, Department of Applied Psychology -, Romania Introduction • In a previous longitudinal study, a relationship was found between social competence and behavioral problems in preschool children [3]. • Externalizing behavior refers to confused relationships with peers and poorer social competence [4]. • According to previous research, social skills and school performance are related to problematic behaviors, and these three are referred to as subdomains of social competences.

Topological photonic systems, with their ability to host states protected against disorder and perturbation, allow us to do with photons what topological insulators do with electrons. Topological photonics can refer to electronic systems coupled with light or purely photonic setups. By shrinking these systems to the nanoscale, we can harness the enhanced sensitivity observed in nanoscale structures and combine this with the protection of the topological photonic states, allowing us to design photonic local density of states and to push towards one of the ultimate goals of modern science: the precise control of photons at the nanoscale. This is paramount for both nanotechnological applications and fundamental research in light matter problems. For purely photonic systems, we work with bosonic rather than fermionic states, so the implementation of topology in these systems requires new paradigms. Trying to face these challenges has helped in the creation of the exciting new field of topological nanophotonics, with far-reaching applications. In this article, we review milestones in topological photonics and discuss how they can be built upon at the nanoscale.

Software development is rapidly growing at a global level. It requires a lot of technical knowledge and a well-structured skill set. Due to these and other factors, software development projects contain elements of uncertainty. Risks can also be defined as the possibility of the occurrence of an event which may either have a positive or negative impact on the result. Risk management is one of the most important functions of management strategies. In project management, risk management plays an important role in preventing and mitigating risks that have the potential to adversely affect the specified outcomes. Artificial neural network-based training algorithm is used to predict the risks in agile software development project. They help project managers in decision making and predicting the risks involved in the projects with respect to the resources, techniques and other constraints involved.


In a number of texts throughout his career, Thomas Aquinas identifies different senses of the term 'esse'. Most notably, he notes that according to one sense, the term signifies the act of existence (actus essendi), which he famously holds is really distinct from essence in all beings other than God. Perhaps surprisingly, he also notes on a number of occasions that according to another sense, the term 'esse' can signify that very principle that he says is distinct from the act of existence, namely, essence. In light of Aquinas's semantic theory, this paper investigates how he coherently holds within his metaphysical system that this term 'esse' can signify in different ways both essence and the act of existence. More broadly, what it shows is how, for Aquinas, the metaphysician can look to the modes of signification (modi significandi) of terms and as well as their modes of predication (modi praedicandi) to draw careful conclusions about the modes of existence (modi essendi) of real beings. These considerations reveal that in Aquinas's view, although the grammarian and logician in their way are also concerned with these semantic modes, it is not their job to employ them to discern the various senses of the term 'being' or the fundamental modes of being. In the end, this is a task for the metaphysician.


The new fluctuation-assisted mechanism for nucleation and crystallization in the isotactic polypropylene/poly(ethylene-co-octene) alloy has been studied. We found that the liquid–liquid phase separation (LLPS) had a dominant influence on the crystallization kinetics through the nucleation process. After LLPS, the nucleation of crystallization mainly occurred at the interface of the phase-separated domains. It is because that the concentration fluctuations of the LLPS induced the motion of polymer chains and possibly some segmental alignment and/or orientation in the concentration gradient regions through interdiffusion, which could assist the formation of nuclei for crystallization. In other words, the usual nucleation energy barrier could be overcome (or at least partially) by the concentration fluctuation growth of LLPS in the unstable regions. This could be viewed as a new kind of heterogeneous nucleation and could be an addition to the regular nucleation and growth mechanism for crystallization. © 2008 Wiley Periodicals, Inc.

Intelligent vehiclesmustmake real-time tactical level decisions todrive inmixed trafc environments. Since repeatable testing of different algorithms in rare and potentially dangerous situations is necessary, we have developed a custom simulator for this task. SHIVA (Simulated Highways for IntelligentVehicle Algorithms)mirrorsmanyaspects of the Carnegie Mellon Navlab [26, 13] system, enabling algorithms developed in simulation to be implemented on the robot with minimal modication. Realistic sensor models encourage developers to create algorithmsthat will work on real robots. Incremental development is facilitated through hierarchies for vehicles, sensors and reasoning objects. An integrated simulation and animation environment provides interactive graphical debugging capabilities.


Vanadyl-phthalocyanine (VOPc) films were prepared on KBr substrate by MBE. They were characterized with RHEED, optical absorption spectra in visible and infrared regions (UV/VIS) and SEM. The thickness of prepared films is above 100 nm. The second and third harmonic generations (SHG and THG) of films were also measured by a Maker fringe method using a Nd·YAG laser. From these results, it was concluded that films are epitaxy films. We also estimated that the SH intensity of VOPc films are about 20 times higher than that of a Y cut quartz crystal and the third-order susceptibility χ(3) of VOPc film is about 3 times greater than the value reported recently by Fang et al.


Law, and therefore courts, can only make sense of collective agency in terms of constituted power that is power exercised in conformity with law. However, constituent power, insofar as it purports to create a new legal order, cannot act in conformity with the existing legal order. Constituent power can only be understood as lawful, therefore, if it is understood retroactively, from the perspective of the new legal order. This article considers the ICJ's treatment of the constituent power of 'the People' in the Kosovan declaration of independence, and the Supreme Court of Canada's consideration of the Quebecois legal right to secede. Considering the literature on constituent power and the ontology of 'the People', this article suggests that democracy and the rule of law offer a partial solution to the paradox of constituent power. It introduces John Searle's ontology of 'institutional facts', arguing that the nature of the constituent entity can be understood as a 'status function' created by a 'Declaration'. It concludes by considering the limits to the justiciability of constituent power.

Possibilities for the preparation of substituted ketones by catalytic dehydrogenation of corresponding secondary alcohols were explored using a ZnO–Cr2O3 catalyst at 370–400°C. It was found that addition of about 1 wt% of sodium to the catalyst increases the yield of the ketone because the competitive dehydration of the alcohol is suppressed. Further improvement of the process was achieved by adding 20 wt% of water to the alcohol feed, which inhibited catalyst deactivation. Preparative experiments were conducted and 1-methoxy-2-propanone, 1-methoxy-2-butanone, 1-phenoxy-2-propanone and 2-methoxy-1-cyclohexanone were obtained.

Question: We provide a method to calculate the power of ordinal regression models for detecting temporal trends in plant abundance measured as ordinal cover classes. Does power depend on the shape of the unobserved (latent) distribution of percentage cover? How do cover class schemes that differ in the number of categories affect power?

Methods: We simulated cover class data by "cutting-up" a continuous logit-beta distributed variable using 7-point and 15-point cover classification schemes. We used Monte Carlo simulation to estimate power for detecting trends with two ordinal models, proportional odds logistic regression (POM) and logistic regression with cover classes re-binned into two categories, a model we term an assessment point model (APM). We include a model fit to the logit-transformed percentage cover data for comparison, which is a latent model.

Results: The POM had equal or higher power compared to the APM and latent model, but power varied in complex ways as a function of the assumed latent beta distribution. We discovered that if the latent distribution is skewed, a cover class scheme with more categories might yield higher power to detect trend.

Conclusions: Our power analysis method maintains the connection between the observed ordinal cover classes and the unmeasured (latent) percentage cover variable, allowing for a biologically meaningful trend to be defined on the percentage cover scale. Both the shape of the latent beta distribution and the alternative hypothesis should be considered carefully when determining sample size requirements for long-term vegetation monitoring using cover class measurements.


Spalangia endius and Muscidifurax raptor multiparasitized house fly pupae. However, S. endius tended to avoid ovipositing in pupae parasitized by M. raptor , whereas M. raptor did not avoid pupae parasitized by S. endius . Behavioral observations indicated that both species could, in some cases, discriminate and subsequently refrain from ovipositing on an already parasitized pupa, but only after drilling into the puparium. Multiparasitism decreased as the time after initial parasitization increased. These findings indicate that the parasitoids use cues, possibly venom, inside the puparium for host discrimination. Multiparasitism should be accounted for in laboratory studies on the reproductive potential of these parasitoids. Furthermore, our results indicate that where these two species are mass released simultaneously, multiparasitism may commonly occur.


Abstract: Forest condition in Europe is monitored under the International Co-operative Program on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests). The focus of the program is to provide an overview of the status of forest ecosystems in Europe with respect to air pollution and contribute to the understanding of the relationship between pollution and forest health. Crown condition parameters, i.e., defoliation and discoloration, are used as the principal indicators of forest condition within the ICP Forest network. Crown condition assessments have been successful in disproving the "forest die-back" hypothesis. However, there are a number of limitations associated with this approach given the current monitoring objectives. Data from crown condition assessments indicate that stand age and country differences explain most of the variation in crown defoliation. It is difficult to clearly discern the effects of air pollution from other site and stress factors. The results do however indicate the role of meteorology and other factors. A better understanding of the relationships between forest condition and air pollution may be achieved if more specific, quantitative response variables are selected. However, we suggest that the original focus of the program on air pollution effects may need to be re-evaluated.


This essay examines how and why Blackwood's Edinburgh Magazine represented Wordsworth as a great poet in the period from 1818 to 1822, in the context of the complex relationship between the Romantic "myth" of genius and the operations of the literary marketplace in the early nineteenth century. A number of strong commercial and ideological reasons contributed to the magazine's support of the poet: for example, its opposition to the Edinburgh Review, and its desire to put forward an account of poetic genius as, ideally, a locus of timeless, orthodox values, rather than a dangerous, transgressive force which threatened the sociopolitical status quo. The second part of the article focuses on the third of John Wilson's "Letters from the Lakes" (1819), a panegyrical account of Wordsworth as both private gentleman and solitary genius. But it is argued that Wilson had ambivalent feelings about his fellow "Lake Poet." He sought both to improve Wordsworth's cultural status, and to offend him by publicizing his private life, thus imbricating him in the contemporary culture of "personality" which the poet so deplored.


Greenhouse gas emissions and energy controls of industrial activities have become a main focus of the Taiwanese government, and because the cost of electricity is rising rapidly nowadays, adopting energy conservation measures to achieve cost savings and sustainable operation is essential for industries. In the textile industry, the energy consumption of A/C systems is second only to that of the manufacturing equipment. This study presents the life cycle costs and payback period by replacing old A/C systems with evaporative cooling systems. Based on the analysis, this study concludes that with evaporative cooling systems using only 10% to 15% of the energy used by A/C systems, the average payback period is less than 0.25 years despite the low electricity tariff in Taiwan. This suggests that for either the short term or the long term, evaporative cooling systems are an economical measure for the textile industry.


The aim of this research is to compeer the optimum conditions for etching CR-39 by using two kind of etchant solution NaOH+H2O, KOH+H2O with various normality and various etching time after irradiated with 3 MeV α-Particles from an 241 Am source during (3 min) by calculation bulk etch rate VB , track etch rate VT , etch rate ratio V, track length L, and length growth rate dL/dt.

Background: Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare autosomal dominant disorder driven by missense mutations in ACVR1. This results in inappropriate activation by activin-A. FOP is characterized by progressive heterotopic ossification and painful soft tissue inflammatory events known as flare-ups. Garetosmab, an investigational, fully human monoclonal antibody against activin-A, prevents formation of new heterotopic ossification lesions in FOP. Here we describe the impact of garetosmab on flare-up events in the LUMINA-1 study (NCT03188666). Methods: This was a post hoc analysis of phase 2 LUMINA-1, a randomized double-blind placebo-controlled study that evaluated the safety and efficacy of garetosmab 10 mg/kg/every 4 weeks intravenous vs placebo in adult patients with FOP over 28 weeks (Period 1), followed by a 28-week open-label treatment period (Period 2) and subsequent open-label extension (Period 3). Patient-reported flare-ups were collected via a patient diary and severity of symptoms was reported as mild, moderate, or severe. Clinician-reported flare-ups were collected as adverse events. Results: In Period 1, there was a significant reduction in the proportion of patients reporting one or more flare-ups (35% vs 71%, p=0.032) and clinician-reported flare-ups (10% vs 42%, p=0.039) with garetosmab vs placebo, respectively. The overall number of patient-reported flare-ups (13 vs 34) and mean days experiencing new flare-ups (42.6 days vs 65.4 days) were also reduced with garetosmab vs placebo, respectively. Most flare-ups occurred in the back in garetosmab-treated patients, and most flare-ups occurred in the lower extremities and back for those on placebo. Pain was the most frequent symptom among both cohorts. Flare-up associated joint stiffness and severity of flare-up associated symptoms were nominally reduced at both patient and flare-up level of assessment in those treated with garetosmab. No patients reported severe swelling or severe decrease in movement. One patient reported severe pain and joint stiffness in the garetosmab cohort. In Period 2, there were significant reductions in the proportion of patients experiencing flare-ups (68% vs 14%, p=0.0002) and number of patient-reported flares (31 vs 11) among those who crossed over from placebo in Period 1 to garetosmab. Patients who continued on garetosmab through Period 2 maintained a sustained reduction in number of flare-ups (12 vs 6) and proportion of patients experiencing flare-ups (33.3% vs 22.2%). Reductions were maintained through the open-label extension. Conclusions: Patients treated with garetosmab experienced significant and sustained reductions in the frequency, duration, and severity of flare-ups. The ability of garetosmab to reduce flare-up events may provide a clinically meaningful benefit for patients with FOP. Presentation: Sunday, June 18, 2023


Pascal's triangle is the most famous of all number arrays full of patterns and surprises. It is well known that the Fibonacci numbers can be read from Pascal's triangle. In this paper, we consider the Fibonacci p-numbers and derive an explicit formula for these numbers by using some properties of the Pascal's triangle. We also introduce the companion matrix of the Fibonacci p-numbers and give some identities of the Fibonacci p-numbers by using some properties of our matrix.


Allergen-specific immunotherapy (SIT) is the only known causal treatment of allergic diseases. The safety and efficacy of SIT have been demonstrated in humans in many clinical trials, which showed the essential role of SIT in preventing new allergies and asthma. However, SIT is not effective in all allergic individuals and is not equally effective in the treatment of various hypersensitivities to different allergens. For this reason, there is a strong need for research in the field of new SIT modalities to increase its effectiveness and safety. They include recombinant allergens or hypoallergenic variants that show the ability to activate T lymphocytes but decrease IgE binding, diminishing the anaphylaxis risk of the treatment. Growing evidence on different T cell subset functions provides new concepts on the safer and more effective vaccination strategies.


GRAPHICAL ABSTRACT ABSTRACT Rational design of title ligands led to the creation of high effective catalysts and perspective luminescent materials. However, novel ligands showed unpredicted properties like spontaneous formation of macrocyclic molecules, unique reversible slitting of macrocycles on to the smaller cycles, rapid interconversion of the isomers catalyzed by both acids and transitional metals, bridging behavior of usually chelating ligands and the unexpected high influence of dangling substituents on N-atoms on to the catalytic and luminescent properties of P-complexes.


In respondents' opinion, the main cause of crisis in Russian science is the decrease in the value of government financing as well as backward material and technical facilities, outflow of personnel, and decline of social prestige of the scientific profession. The present state of R-D institutions is assessed also negatively. One of the indications of unfavourable situation is the outflow of specialists from R-D institutions. The main reason of departure is a low rate of salary (78 per cent of respondents). Other most important reasons are an unstable situation of R-D institutions (43 per cent) and decline of the social status of scientists (22 per cent). To some extent the existing discontent with earnings is compensated by a wider range of sources of income for R-D representatives with a higher qualification. Most opportunities, besides primary employment, are possessed by doctors of science. It refers practically all possible sources of income both within the country and abroad, especially such as grants, contracts, agreements, teaching, publications, and travel expenses. Less opportunities are available for candidates of science and quite little for researchers without an advanced degree. In the respect of anticipated unemployment, R-D professionals are a more vulnerable part of the economically active population. Probability of losing job for grounds not depending on an employee, assessed by Russian scientists, is higher and their confidence in finding a new job for their specialty is lower than the average for all categories of employees. Approximately one in seven does not identify oneself with any of the social groups. Slightly less than half of respondents rank themselves among the middle class or higher. A considerable divergence is found in the distribution of selfassessments of Russian scientists' social position in this country and positions of specialists of the same qualification in other countries. In Russia they are on the average twice lower than abroad. The indicator of confidence in the future is also very low.

We analyze the flat space limit of 3-point correlators in momentum space for general conformal field theories in even spacetime dimensions, and show they exhibit a double copy structure similar to that found in odd dimensions. In even dimensions, the situation is more complicated because correlators contain branch cuts and divergences which need to be renormalized. We describe the analytic continuation of momenta required to extract the flat space limit, and show that the flat space limit is encoded in the leading singularity of a 1-loop triangle integral which serves as a master integral for 3-point correlators in even dimensions. We then give a detailed analysis of the renormalized correlators in four dimensions where the flat space limit of stress tensor correlators is controlled by the coefficients in the trace anomaly.


What happened last autumn, when it was considered that problems for a single player the hedge fund Long Term Capital Management might create grave difficulties for the financial system in the United States, highlighted risks of a new type. The LTCM case can be seen both as an extreme example of what could happen in Sweden's financial markets and as a serious reminder that the continuous development of financial markets is liable to give rise to new risks. The suspension of payments in Russia and its consequences should likewise lead us to reflect on the risks in the system.

Non-invasive cognitive neuroimaging studies based on functional magnetic resonance imaging (fMRI) are of ever increasing importance for experimental and computational neurosciences. This was made possible mainly due to the availability of fast and reliable functional MRI protocols in which the brain's own hemoglobin content is used as the nature's own contrast agent. Such fMRI based cortical activation maps however, provide only the localization information of the brain, leaving its pattern of connectivity elusive. The explanatory power of the current functional MRI studies could be greatly expanded therefore, if the same MRI framework could be utilized to assess the pattern of neuronal connectivity in vivo. To this end, we have performed simultaneous fMRI and diffusion tensor imaging (DTI) based fiber reconstructions in order to elucidate the organization of large-scale neural networks governing specific cortical functions, such as the object recognition along the ventral stream. The methods developed in this study have the potential to lay foundation for in vivo functional neuroanatomy that can provide data fore more empirically-motivated neural network models in future.


In the situation of CPU and memory overcommit, it is inevitable that some NUMA nodes will be overloaded or hotspotted and become hot nodes, leading to the VM application performance degradation in virtualized NUMA (vNUMA) systems. However, the virtual machine monitor (VMM) can not be aware of the NUMA feature and the distribution array of hot memory pages amongst NUMA nodes effectively. Aiming at eliminating the hot nodes and load imbalance in a vNUMA system, this paper proposes a hot-page aware scheduling optimization method (HASO) and implements a HASO scheduling system. At first we monitor the NUMA node load state, find the hot nodes in which we choose the hot VMs that cause the node hotspots. Then, we predict the distribution of future hot memory pages of the hot VM, and evaluate the cost of migrating the hot pages between NUMA nodes. At last, the hot pages of hot VM with minimized migration cost are migrated to idling nodes, so as to eliminate the hot node and improve the VM application performance. In contrast to the default scheduling mechanism of VMM, our HASO scheduling method can not only improve the memory intensive benchmark cg by up to 27.06% and the benchmark stream by up to 15.63%, but also balance the load of NUMA nodes.

Peritoneal disseminations from lung cancer are difficult to detect during the patient's clinical course. Therefore, complications of this condition are unclear. We report a case in which peritoneal dissemination from lung cancer complicated appendicitis.


The flexural bearing is used for micro-machining and precision applications where low displacement is involved. It offers the advantage of almost frictionless, vibration free and maintenance free operation. The bearing element is deformed to provide desire relative motion between the surfaces. They are made up of deformable bodies called flexure. These flexures are to be designed for required displacement. However the analytical procedure for analysis of the flexure is not available. Hence, an alternative approach of using FEA is applied for design of flexure analysis. In this work flexure having different size and shape such as triangular, square, rectangular and elliptical are analyzed. The analysis of all the above shapes with various thicknesses for least axial, maximum radial stiffness and equivalent stresses is made. Later the results have been analyzed to choose optimum design of flexure.


The design for a confocal beam-scanning microscope with a unique optical configuration for the rapid acquisition of spectrally resolved images is presented. The novel aspect of the optical configuration is the location of the detection device, which is placed in an intermediate position between fully descanned detection and nondescanned detection (direct projection). This placement allows for the practical implementation of spectrally resolved confocal imaging. The device is demonstrated by the spectral resolution of a sample of fluorescently labeled microbeads.
