This thesis presents results from a systematic study undertaken to establish the influence of sulphur dioxide (SO2 and O2) content on the critical water content required to initiate substantial levels of internal corrosion during the transport of supercritical CO2 for Carbon Capture and Storage (CCS) applications.
An assessment of both the general and localised corrosion behaviour of X65 carbon steel in water-containing CO2 environments is presented. Firstly, autoclave experiments were conducted in environments where the CO2 phase was either saturated or under-saturated with water. Such an approach enabled identification of the minimum water content in the system, below which no general or localised attack was observed.
Later, corrosion experiments were performed containing supercritical CO2 and the presence of 0, 50 and 100 ppm SO2 with a low level of O2 (20 ppm). The results highlights that reducing water content is a more favourable option compared to reducing SO2 content to minimise corrosion in the system as high corrosion rates can be observed in the absence of SO2 if water content is high enough, but below a minimum water content (~500 ppm), both general and localised corrosion is minimal despite the presence of 100 ppm SO2.
Analysis of corrosion products formed on the steel surface is performed using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray spectroscopy (EDX), Transmission Electron Microscopy (TEM), Raman spectroscopy. Only FeCO3 was detected on the surface without SO2 and O2, whilst both FeCO3 and FeSO3.3H2O were identified on the surface of the carbon steel samples exposed to the environments containing 2 and 100 ppm SO2 and 20 ppm O2. The localised corrosion rates were determined by surface profilometry measurement.
The most important observation from this work is that the key degradation mechanism in all experiments was localised corrosion. Not only was the combination of SO2 and O2 shown to influence pitting severity, but the pitting rates recorded were nearly one order of magnitude greater than the uniform corrosion rate determined from mass loss measurements. The increase in SO2 content was shown to influence the shape of pits as well as their overall depth. In particular, the work highlights the importance of adopting a systematic approach when determining pitting behaviour of carbon steels exposed to impure dense-phase CO2.


Objective To explore the effects of cryotherapy on the angiogenesis and VEGF protein expression of glioma, and the correlation between VEGF protein expression and microvascular density. Methods Mouse experimental models with G 422 glioma were established. Experimental mice were randomly divided into control group and freezing group. MVC and VEGF protein expression were detected by immunohistochemical staining at different time after the freezing. Results MVC and VEGF protein expressions in freezing group were decreased. The lowest value was detected in 2 or 3 days after freezing. The value increased slowly after that. There was no change in MVC and VEGF protein expressions at different time in control group (P0.05), suggesting a positive correlation between VEGF protein expression and MVC(r=0.87, P0.01). Conclusions Cryotherapy can considerably reduce the density of neovascularizations around the glioma and the VEGF protein expression, thus inhibiting the growth of glioma from the perspective of blood vessel formation.


Khairu Ummah appears in surah 3:110 associated to the society on which Prophet Muhammad lived. This term shows that there is a supreme concept of the highest level of civilization since the society of that period is considered as an excellent civilization. There are several requirements to fulfil in order to reach the status of khairu ummah, those are the promotion of virtue, prevention of vice, and Iman in Allah. However, those requirements are very general thus it is necessary to decipher specific aspect to reach one of them. In another surah, Al-Hujuraat (49), Allah detailly explains the major features of the Mu'minun (those who believe). Of the features is Tabayyun, appears in the sixth verse in the context of incoming information. Examining the semantic concept of Tabayyun is a step to reveal the specific aspect to gain the status of the ideal Ummah. This work is deciphering the concept of Tabayyun according to the Qur'an through two main approaches: Semantic analysis and Composition examination. These both methods are conducted by two distinguished contemporary scholars, Toshihiko Izutsu and Hamiduddin Al-Farahi, to find the philosophical meaning of a particular term from the Qur'an. Eventually, it is concluded that the Tabayyun definition is an important high-level social ethics that only true believer can perform it. The absence of Tabayyun leads not only to a wrong decision but to a major conflict in society even the disintegration of it.


In the Remote Sensing Center we are solving problems within the framework of the state plan of technical development, "Aerospace research of the environment of Czechoslovakia." For measurements in situ we are using Spectroradiometer LI-1800. This device enables to measure spectral reflectance in the range of wavelengths from 300 nm to 1100 nm. It means that visible and near infrared (NIR) regions of spectra are covered. LI-1800 can be used to measure under laboratory conditions or in situ. Under laboratory conditions it has been used to measure more than 100 samples of typical soils. We correlate our measurements with main pedologic factors. In cooperation with the Slovak Academy of Sciences we measure in situ spectral reflectance of the different soil types simultaneously with overflight of the Landsat Thematic Mapper. For purposes of observation of negative effects of open-cast coal mining on the surrounding environment, we have measured spectral reflectance of the forests. There are great differences between healthy and damaged trees, especially at the NIR spectral region. We are looking for dumps with rock-oil waste and its influence in water. In cases of ecological breakdown caused by leaks of rock-oil and its products, we measure reflectance of the vegetation. We use our Spectroradiometer onboard a helicopter, too. In this case we can simultaneously take photographs and measure reflectance. We derived a relationship between optical density of photographs on different spectral regions and spectral reflectance.

An in-line high efficient polarizer, composed of tapered fiber on the Au thin film, is theoretically proposed and experimentally demonstrated. The protocol is based on the high efficient adiabatic conversion of transverse magnetic mode from tapered fiber into surface plasmon (SP) and attenuates quickly in metal film. On the contrary, the transverse electric polarized light is influenced hardly in the whole process. The polarization extinction ratio higher than 500:1 (≈27 dB) is obtained in our experiment. Our demonstration offers a potential way to manipulate the polarization of light in integrated circuit and may inspirit more attention to surface plasmon based devices for polarization controlling.


The conventional IMU dynamic test system method has two shortcomings,no uniform time marker and low efficiency.To resolve these questions,a dynamic test system based on the xPC kernel is designed.As for this test system,firstly,the general design and the flow design are finished.Then the key techniques are studied,which mainly includes the design of the test control platform software and the realization of the parameter download,the design of the IMU communication module,the design of the three axis table data communication module,the design of the software used for the read-time data save and display,and so on.The test system can ensure that the data acquisition is finished in the same read-time clock.Long term test indicates that the sample frequency of this test system can achieve 1 kHz without error in 10 minutes,so it is proved the validity of the system.


The transition process of high school students to university education and college life is quite challenging. Therefore, this process should not be unguided, as this research paper suggests, in order to equip the high school students with the necessary skills and background to enable them to go through this phase successfully. There should thus be a strategy or programme for the teachers and the administrative staff to be implemented in the high schoolsto achieve


CARCELY A WEEK passes that we do not read in the S medical literature or in the public press, of some new breakthrough in cancer research. On the other hand, some recent studies, such as that of Drs. Bailar and Smith,' have presented a much more sober picture. They studied the overall progress against cancer in the United States from 1950 to 1982 and found that between 1962 and 1982 crude mortality rates increased by 25% and ageadjusted mortality rates increased by 8.7%. From 1973 to 198 1 the crude incidence rate for cancer rose by 13%, and the age-adjusted rate by 8.5%, while 5-year survival rates rose from 38.5 to 40. I%, a 4.2% increase. Adjusted rates for expected mortality from other causes rose from 46.8% to 49.2%, an increase of 5.1%. This slight rise in overall mortality was mainly due to increased mortality in males and by an epidemic of lung cancer, and was slightly ameliorated by a decrease in the mortality due to colorectal, stomach, and cervix cancers. Bailar and Smith concluded that "we are losing the war against cancer, notwithstanding progress against several uncommon forms of the disease, improvements in palliation, and extension of the productive years of life," and "that some thirty-five years of intense effort focused largely on improving treatment must be judged a qualified failure." If we examine whether we are winning or losing the war against cancer, the truth, as usual, lies between the two extremes2 The rocket-like speed with which scientific data are being accumulated on all aspects of cancer is not reflected in the apparently Pony Express speed with which we are affecting cancer as an illness or as a cause of death. Neither view is entirely accurate either in terms of what is really happening or in its description. The Pony Express that began in April 1860 looked like a rapid method of communication until the first telegraph message was sent from San Francisco to Washington 1.5 years later; what was quite a significant accomplishment has become, therefore, synonymous with a lack of progress. The research that put Neil Armstrong on the moon in 1969 also has a longer history than is generally appreciated. Cen-


This study addressed a discrepancy between theories of program choice and observed audience behavior. It found that expected patterns of choice are significantly enhanced when viewing groups are constant over time.


Microvascular reconstruction of maxillary composite defect after oncologic resection has improved both esthetic and functionai aspect of quality of life of the cancer patients. However, a lot of patients had prior surgery with radiation and/or chemotherapy as a part of comprehensive cancer treatment. Sometimes it is nearly impossible to find out adequate recipient vessel for maxillary reconstruction with microvascular anastomosis. Therefore long pedicle of the flao is needed to use distant neck vessels located far from the reconstruction site such as ipsilateral transverse cervical artery or a branch of contralateral external carotid artery. For this reason, although we know the treatment of the choice is osteocutaneous flap, it is difficult to use this flap when we need long pedicle with complex three dimensional osseous defect. Vascular option for these vessel-depleted neck patients can be managed by a soft tissue reconstruction with long vascular pedicle and additional free non-vascularized flap that is rigidly fixed to remaining skeletal structures. For this reason, maxillofacial reconstruction by vascularized soft tissue flap with or without the secondary restoration of maxillary bone with non-vascularized iliac bone can be regarded as one of options for reconstruction of profound maxillofacial composite defect resulted from previous oncological resection with chemoradiotherapy.


Silver nanoparaticles with different shapes and sizes were prepared by injecting silver nitrate acetonitrile solution into the heated benzaldehyde.Then nanosilver-fullerene composite was formed by the same procedure except benzaldehyde was displaced by the mixture of benzaldehyde and C_60 xylene solution.The as-synthesized products were identified by X-ray diffractometry(XRD), transmission electron microscopy(TEM),high-resolution transmission electron microscopy(HRTEM),Fourier transform infrared spectroscopy(FT-IR).The formation mechanisms of silver nanoparaticles and nanosilver-fullerene composite were discussed.


Deadwood moisture affects multiple functions of downed logs in forest ecosystems. They include provision of habitats for xylobionts, additional water stores and organic carbon stocks. In contrast to Northern American forests, little is known about moisture variability in downed logs of important tree species within the Temperate Zone of Europe. Therefore, our study aimed at elucidating this variability according to species, site and decay class (DC). Measurements were taken by TDR during two vegetation periods in eight Carpathian natural forests representing distinct site conditions, ranging from xerothermophilous to subalpine. Downed logs of Quercus spp., Abies alba Mill., Fagus sylvatica L., and Picea abies L., belonging to various DCs, were selected and instrumented with TDR probes. Species and DC‐specific TDR calibration showed the importance of intrinsic wood porosity. The course of deadwood moisture consisted of drying during the early decay stage, except for A. alba and F. sylvatica, and an intense water reabsorption at later decay stages. Average moisture for all species and sites displayed seasonal trends, reflecting the occurrence of precipitation clusters and dry periods, as well as short‐term fluctuations. Cross‐spectral analysis revealed that both sapwood and heartwood participated in wetting and drying processes, but only after reaching an advanced stage of decay. New findings can be applied in interpreting, modelling and predicting deadwood water stores, habitat properties and respiration. Copyright © 2011 John Wiley & Sons, Ltd.


China's so-called political practice. To sum up, whatever perspective we take in reading The China Model, be it a critique of democracy, a meritocratic theory based on political practice, or a Confucianist approach, Bell's argument fails for similar reasons. First, he ignores existing literatures that are crucial in challenging his theory, or in other words his real theoretical enemies, which gravely damages the credibility of his theory; second, his understanding of the political practice of China is ill-founded or maybe even conjectural. What adds to the predicament of Bell's theory is that his treatment of the Western democratic trajectory as a precedent of China's democracy is largely incoherent. Taking all these problems into consideration, his argument for a three-layered political system with meritocracy at the central level is fundamentally unsuccessful.


A field experiment was conducted during Kharif, 2016 and 2017 in sandy clay loam soils of experimental field at Banaras Hindu University, Varanasi, Uttar Pradesh to find out the effect of leaf colour chart based nitrogen and weed management practices on yield attributes, yield and economics of direct seeded rice. The experiment was laid out in split plot design with four main plot treatments and five sub plot treatments which were replicated thrice. It was found that superior performance of rice in terms of yield attributes and yield was observed with application of nitrogen @ LCC < 5 (N4). Among weed management practices, maximum Weed control efficiency, yield, gross returns, net returns and B: C ratio was recorded with application of pyrazosulfuron @ 20 g a.i ha (PE) fb bispyribac @ 25 g a.i ha at 1520 DAS (W4) which was comparable with two hand weedings at 20 and 40 DAS (W1) while weedy check (W0) recorded lowest weed control efficiency, yield and yield attributes and economics.


According to previous research, people with ASD may prefer to see or execute the details instead of the overall image. This could support a greater preference for images with angular shapes to curved images. The improved perceptual functioning model (EPF) postulates an increased local perception of low level in people with ASD. The presence of the vertices of the angular forms can maximize the salience of the form and facilitate the representation of the object in people with ASD. Method: The sample was composed of six people, who

The use of Cartesian grids is proposed to treat domain integrals encountered in the numerical solution of Poisson equations with boundary integral equations.Traditionally,domain integrals are treated by using internal cells,which makes the algorithm stable and accurate but takes much human labor.By introducing Cartesian grids,the time for data preparation is greatly reduced while keeping all merits of using internal cells.This is because cells have nothing to do with the handling of boundary conditions and the construction of related shape functions in the boundary type methods,but are only for evaluation of the domain's influences on the boundary unknowns.Techniques of using Cartesian grids are developed and combined with the newly developed boundary-type numerical method,the boundary point method,to solve the Poisson equations.Several numerical examples are presented to show feasibility and accuracy of the proposed algorithm.The effects of the relation between spacing of Cartesian grids and the support of the boundary points on accuracy are investigated in the computations.


This paper describes the road haulage association (rha) and gives details of the road transport industry in the UK. In 1984 1675 million tonnes of goods were carried by road, 20545 million were spent on road freight conveyance, nearly 98% of the overall total of road and rail, the structure and operation of motorized road haulage in the UK, its place in international freight transport and the process of harmonisation of vehicle weights and dimensions within the eec. The role of the lorry in the community and attitudes to the lorry are discussed as is the present road network and need for more motorways. The author ends by looking at the future and stresses the need for the industry to participate fully in practical attempts to reduce any ill-effects of the lorry in towns and cities. The trend is for haulage operations to become an integral part of the chain between the producers of raw materials and the consumer. Haulage operations are becoming more sophisticated providing flexibility and speed of delivery with the help of increasing technology such as computers.

Adolescents' mental health issue has become an imperative focus of the youth development. According to WHO (World Health Organization) report, adolescents with mental health issues are more susceptible to social isolation, discrimination, stigma (which can impair their willingness to seek care), academic challenges, risk-taking behaviors, physical ill-health, and human rights abuses. Hence, we need to take efficient, customized, and collective actions to protect adolescents from further deterioration and solve their mental problems in a timely and specific approach. Out research team strives to investigate the antecedent, solution, mechanism for the youth mental health wellbeing. The projects has last two years and keep on collecting more quantitative and qualitative evidence and implications for establishing a universal-design, person-centered, and evidencebased digital therapeutics for youth development towards Post COVID-19 new normal.


Summary 1. When whole blood from polonium-injected rats or dogs was centrifugally fractionated, it was found that approximately 90% of the polonium was associated with the red blood cells. 2. Isolation of hemoglobin from similar blood indicated that the polonium was associated with this portion of the red blood cell. Fractionation of hemoglobin into globin and heme indicated that almost all of the polonium was associated with the globin. Measurement of the affinity of major red blood cell components for polonium demonstrated that globin had as much affinity as lysed whole red cells, while heme residue had practically none. 3. Chemical methods which rely on a change in hydrogen ion concentration for the isolation of polonium containing red blood cell components were not satisfactory.


We are undertaking a large galaxy survey centred on distant bright quasars in the form of the VLT LBG Redshift Survey (VLRS) to probe the intergalactic medium (IGM) of z ~ 3 galaxies. At present the VLRS survey consists of 9 fields in total, with spectroscopic observations of ~3,000 Lyman break galaxies (LBGs) taken with VLT VIMOS. We have also made the photometric observations of Lyman-alpha emitters (LAEs) in the deep imaging fields of the VLRS, taken by using Subaru Suprime-Cam, and aimed at studying the clustering properties of LAE galaxies. In this research, we use data from 7 fields to conduct the auto-correlation function of LAEs. We find the correlation length of with a slope ofwhich are in agreement with those of previous observations. Keywords : galaxies, evolution, high-redshift


Hepatitis C virus is among the most common cause of viral hepatitis which considered as a major public health problem worldwide. This study was aimed to determine the prevalence of hepatitis C (HCV) antibody among patients attending Sokoto Specialist Hospital, using Acon ® Laboratory Inc, test kits, after the patients were advised on the need to know their status Of the 300 blood samples tested, 8 (2.7%) was positive for the presence of hepatitis C. Demographic variables (Occupation, Sex, Marital status and education) and risk factors (History of blood transfusion, history of sexual transmitted diseases, intravenous drug abuse and presence of tribal mark or tattoos) appeared not associated (p> 0.05) with the prevalence of HCV antibody. However, there is urgent need to take public health measures to reduce disease burden and transmission, by routine screening of all for HCV infections.

AIM:To study the expression of metastasis suppressor gene KAI1 mRNA in osteosarcoma tissue and osteosarcoma cell lines,and the relationship between it and the biological behavior of the tumor cells.METHODS:RT-PCR was used to detect KAI1 mRNA in 18 cases of resected fresh osteosarcoma samples and three cultured osteosarcoma cell lines.The proliferative rate,the adhesive and invasive abilities of the 3 cell lines were detected.The results were treated by analysis system of images and analyzed with t test.RESULTS:The relative amount of KAI1 mRNA in osteosarcomas with lung metastasis was 0.80±0.50,while that was 1.48±0.64 in osteosarcomas without lung metastasis,the former was significantly lower than the latter(P0.05).However,KAI1 mRNA had no corelation with the recurrence of osteosarcoma.The expression of KAI1 mRNA in U2-OS was highest(P0.05),while the proliferation rate,the adhesive and invasive ability of U2-OS were the lowest among the 3 cell lines(P0.01).CONCLUSION:The metastasis suppressor gene KAI1 might take part in influencing the lung metastasis of osteosarcoma,which might be caused by inhibiting the tumor cell proliferation,adhesion and invasion.


We have investigated the spin Seebeck effect (SSE) generated by current induced-heating in ultra-thin yttrium iron garnet film (20 nm) covered by an 8 nm thick Pt layer. By passing current in the Pt layer, an out-of-plane temperature gradient is established that, in turn, generates an out-of-equilibrium magnons population. The resulting pure spin current is detected using the inverse spin Hall effect (ISHE) measured in the Pt electrode. A lock-in detection scheme is used to separate the SSE signal from other magneto-galvanic effect. Indeed, the SSE signal is obtained as the second harmonic voltage response, while spin Hall magnetoresistance (SMR) is measured as the first harmonic response to the ac excitation current. Interestingly, the amplitude of the SSE in such thin YIG film is comparable to what has been reported for much thicker films.We have investigated the spin Seebeck effect (SSE) generated by current induced-heating in ultra-thin yttrium iron garnet film (20 nm) covered by an 8 nm thick Pt layer.

OBJECTIVE
To study the pathological changes and morphological features of cellular response on the implanted posterior chamber intraocular lens (IOL) in rabbits and discuss the mechanism of postoperative intraocular inflammatory response.

METHODS
9 adult pigmented rabbits were divided into three groups. IOLs were extracted on days 1, 7 and 14 after IOL implantation. Pathological changes on IOLs were observed with light microscopy and scanning electron microscopy, and the number of inflammatory cells on IOLs were counted. The data were analyzed by using analysis of variance of SAS software.

RESULTS
There were inflammatory cells distributed over the entire IOL surface. In the mean time this study had clearly shown that morphological transformation of macrophages into spindle-shaped fibroblast-like cells took place on IOL, and phagocytic particles were in the cytoplasm of fibroblast-like cells, epithelioid cells and macrophages on the IOL.

CONCLUSIONS
The phagocytic ability of fibroblast-like cells, epithelioid cells and macrophages is relatively strong, and besides macrophages and eosinophils, there were many lymphocytic clusters on the IOL, suggesting that an active immune response exist on the IOL surface.


Objective To study the preparation method and quality standard of chemical reference of Juemingzi(Semen Cassiae)-rubrofusarin-6-O-β-gentiobioside,and lay a material foundation for controlling quality of crude Juemingzi and its relevant products.Methods Crude Juemingzi was extracted with 30% alcohol,and reference of rubrofusarin-6-O-β-gentiobioside was isolated and prepared by using solvent method,silica gel and C18 reversed phase column chromatography.The structure was determined by ultraviolet spectrum(UV),mass spectrum(MS),1H-NMR and 13C-NMR and the purity was detected by using thin layer chromatography(TLC) and high performance liquid chromatography(HPLC).The condition of TLC was silica G thin layer plate and 3 different developing solvent systems.The procedure of HPLC was performed on SunFire C18 column(150 mm×4.6 mm,5 μm),mobile phase was acetonitrile-0.1% of phosphoric acid solution(22∶78),flow velocity was 0.1 mL/min,and detection wavelength was 210-400 nm.The homogeneity was checked by using HPLC.Results The yield rate of rubrofusarin-6-O-β-gentiobioside was 0.39%,and the result of TLC examination showed totally single and round spots.The purity was over 98.00% after HPLC determination,and result of variance analysis on the homogeneity showed FF0.05(14,30),which was appropriative.Conclusion The isolated and prepared method of rubrofusarin-6-O-β-gentiobioside is simple and feasible,and its purity and homogeneity are in accordance with the demands of chemical reference.The method can meet the needs of the quality control of crude Juemingzi and its relevant products.

With the developing trade, the customs issue has become more and more on the agenda in the international arena. Over time, various treaties and agreements have been made between the states on customs in order to make trade better as a result of changing conditions. With these treaties and agreements, it has been ensured that international trade is carried out in a healthy way. After signing these treaties and agreements, the Republic of Turkey has started to implement various practices regarding customs. In line with the needs of the country, providing exemption from customs duty for products to be brought from abroad is one of these implementations. Between 1929 and 1950, tax exemptions at Turkish customs were mainly about the tools and equipment to be supplied from abroad in order to develop the industry in the country. While the exemption practices continued in this way, a change occurred in the Turkish political life as of 1950. After the Democrat Party emerged as the first party in the general elections in 1950, the Democrat Party took its place in power. The Democrat Party followed different policies from previous administrations for the development of many fields such as political, social, economic, education, culture and health during its stay in administration. As a result of these policies, the party has brought about changes in many areas during its 10-year period in power without interruption. One of the areas where change took place was customs. Although the new administration has basically acted on the purpose of developing and progressing the country in customs duty exemption practices, like the previous administration, it has done so by taking into account the principle of establishing closeness with western states while continuing the exemption practices in line with the needs of the country. In this study; during the 10-year rule, the customs tax exemption practices of the Democrat Party Governments, in which areas these applications were made and which countries benefited from these exemptions will be tried to be examined in the light of the documents of the Republic Archives, taking into account the political, economic and social conditions of the period.


Effective postoperative pain relief is an essential component of the peri-operative care of the surgical patient. Opioids are commonly employed analgesics for managing postoperative pain. The present study was aimed to compare the efficacy and safety of nalbuphine and fentanyl for postoperative pain relief in short surgical procedure. Sixty patients, scheduled for various short surgical procedures belonging to ASA I & II assigned randomly into two groups (n=30). Group N and Group F received nalbuphine 0.25 mg\kg and fentanyl 1.5 ug\kg respectively before 5 minutes of induction of anesthesia .The patient observed for postoperative analgesia, recovery criteria and side effects. Patients who received nalbuphine had significantly lower pain sores at 1 hour (p<0.05) and 2 hours (p<0.05) and required significantly (p<0.05) less postoperative analgesia. Duration of post operative analgesia was longer in group N than group F. No significant differences were found in recovery from anesthesia. No significant side effects were found among two groups. Freedom from controlled drug act regulations and improved analgesia without respiratory depression, nalbuphine, make it more suitable for day case surgeries.


Objective To have an understanding of the characteristics with or without suicidal ideation among suicide attempters as a first step in psychological crisis intervention strategies.Methods Suicide attempters of emergency department of 4 tertiary general hospitals in Shenyang during the same period were interviewed.They were assessed with questionnaires on Beck scale for suicide ideation(BSS) and diagnosed with a structured psychiatric examination based on DSM-Ⅳ criteria.Results There were no significant difference in sex,age,years of education between the two groups(P0.05).However,there were significant differences in the interval they had considered this time suicide before acting,the main aim of the self-harm,the degree of thinking to die,the attitude to the suicide and so on between the two groups(P0.01).Conclusion There are substantial differences between suicide attempters with and without suicidal ideation.


Abstract In 2015, a new method made it possible to determine shared genetic influences across phenotypes on a scale far greater than ever before. Linkage Disequilibrium Score Regression (LDSR) allows estimation of genetic correlation, revealing the magnitude and direction of shared genetic effects between pairs of phenotypes. Genetic correlation results for a particular phenotype—such as schizophrenia—are similar to epidemiological results. They reveal fundamental information relevant to patterns of comorbidity—but are even more informative because the cause (polygenic variation) is known. Here we report genetic correlation analysis of schizophrenia with 172 diverse phenotypes (psychiatric, medical, personality, and metabolic). This was an analytic study design, which leverages large-scale data resources. In all, approximately 1.5 million individuals participated in the genome-wide association studies (GWAS) that make these analyses possible. We used linkage disequilibrium score regression (LDSR) as implemented in LDHub, and report results with original values, Bonferroni correction, and Benjamani-Hochberg false discovery rates to address multiple testing. The main outcomes and measures are genetic correlations between schizophrenia and 172 phenotypes. As has been previously published, there are positive genetic correlations between schizophrenia and other psychiatric disorders; the strongest genetic correlation is with bipolar disorder (rg = 0.8312, se = 0.0369,  = 2.3e-112). Novel findings reveal genetic effects shared between schizophrenia and the personality traits of neuroticism (rg = 0.1815, se = 0.067,  = .0065) and openness to experience (rg = 0.2108, se = 0.075,  = .0046), the latter of which contradicts epidemiological observations. All other genetic correlations were consistent with epidemiological evidence. Findings suggest that long recognized comorbidity between various immune processes and schizophrenia, and also cigarette smoking and schizophrenia, are at least partly due to shared genetic influences. In the future, the pattern of genetic correlation results for each phenotype—a "genetic correlation profile"—will be common knowledge. These results provide a reasonable first draft of the genetic correlation profile for schizophrenia. They affirmatively answer long-standing questions about the possibility of shared genetic effects on immune, metabolic, and other classes of phenotypes, with schizophrenia. These results also clarify reading of the epidemiological literature, highlighting the lower than average body mass index of individuals prior to developing schizophrenia and prior to taking antipsychotic medications. Results that initially appear surprising may prove to be most useful. These results suggest tractable hypotheses that may lead to major cross-trait discoveries and to reconceptualization of underlying biological processes.

With the development of artificial intelligence (AI) and 5G technology, the integration of sensing, communication and computing in the Internet of Vehicles (IoV) is becoming a trend. However, the large amount of data transmission and the computing requirements of intelligent tasks lead to the complex resource management problems. In view of the above challenges, this paper proposes a tasks-oriented joint resource allocation scheme (TOJRAS) in the scenario of IoV. First, this paper proposes a system model with sensing, communication, and computing integration for multiple intelligent tasks with different requirements in the IoV. Secondly, joint resource allocation problems for real-time tasks and delay-tolerant tasks in the IoV are constructed respectively, including communication, computing and caching resources. Thirdly, a distributed deep Q-network (DDQN) based algorithm is proposed to solve the optimization problems, and the convergence and complexity of the algorithm are discussed. Finally, the experimental results based on real data sets verify the performance advantages of the proposed resource allocation scheme, compared to the existing ones. The exploration efficiency of our proposed DDQN-based algorithm is improved by at least about 5%, and our proposed resource allocation scheme improves the mAP performance by about 0.15 under resource constraints.

Social determinants have a fundamental impact on oral health, which includes oral health care habits. Caregivers can be a key factor to develop them in their children. Objective: Understand the oral health care practices of caregivers and children aged 2 to 5 years in their homes, recognizing their experiences, achievements, and difficulties. Design: Qualitative study obtained in in-depth interviews with 20 caregivers, attending family health centers in the Santiago Metropolitan Region. Results: Caregivers feel responsible for their children's oral health care, while fathers and children seem to have a more passive role than the mother. They value dental care at CESFAM, but they are worried about their future long-term care. Oral health is related to aesthetics and better job opportunities. The primary teeth are essential, but permanents are more relevant; however, they do not believe that they remain in mouth for life. Caregivers handle correct information about oral health care. They hope that their children will not live negative dental experiences. Conclusion: The clinical and educational dentistry strategies should consider the children's social environment, and working as a teamwork with caregivers. It is relevant to conduct further studies on how social determinants affect oral health. Vol. 13(2);


In 1967, the world-renowned African American choreographer Katherine Dunham moved to East St. Louis to open the Performing Arts Training Center (PATC), which offered free classes in dance, music, theater, and other art forms. This article examines why Dunham's center flourished during the late 1960s and early 1970s and argues that her success lay in forging a middle path between liberal policymakers, who funded the PATC, and the city's Black Power youth, who were her primary constituents. She understood the language of both the "culture of poverty" and the cultural revolution; she found common ground between the two by championing African diasporic performing arts education as a means of individual and community improvement. Although Dunham's middle-ground approach had its limitations, the PATC bettered the lives of many East St. Louis residents and can serve as a model for urban arts programs today.


Osteoporosis is one of the major health problem affecting postmenopausal women. Estrogen deficiency results in an increase in bone turnover, lead to bone resorption and an increase risk of fracture. The aim of this study was to evaluate the effects of Platycodon grandiflorum A. extract (PG) in bone metabolism in ovariectomized estrogen-deficient rats. Two groups were surgically ovariectomized (OVX). The third group was sham operated. Sprague-Dawley female rats were randomly assigned to the following groups : sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with PG at 50mg/kg body wt (OVX-PG50) The Platycodon grandiflorum extracts were orally administrated at 1mL per day. The ovariectomy caused a decreasing in the levels of collagen content in bone, cartilage and skin tissues. However PG group, supplementation with Platycodon grandiflorum extract, were increased the level of collagen content in bone, cartilage and skin tissues than OVX-control group. PG group had a higher content of pyridinoline in collagen than OVX-control group. Alkaline phosphatase activity on serum were decreased after supplemented with the PG extract. These results might be expected that Platycodon grandiflorum is believed to be possible protective effects in postmenopausal bone loss.


During Aug.-Oct.1994 and Nov-Dec.1995, the studies on the fragmentation of habitats used by Elliot^s pheasant were done in Shuiwu, Xiaobeilong and Yancun of Kaihua County, western Zhejiang with field observation and measurement. The index of the fragmentation (F) and its formula were produced in this paper. The fragmentation of the habitats, used by Elliot^s pheasant was measured with this index. The results showed that the habitat fragmentation and loss would cause the loss of habitats used by Elliot^s pheasant.


The optimal design of a twenty-five bar space truss commonly involves multiple loading conditions acting on 4 node elements in the linear elastic model. In this paper, we describe the behavior of the truss system with our experimental loading conditions on five node elements subject to minimum displacement and stresses that are used to formulate the constrained nonlinear optimization problem. Numerical computations are developed with the objective of mass minimization and the best structural design is selected by applying the interior point method with the guidance of Matlab Optimization Toolbox. Our numerical results show the optimal values of cross-sectional areas, material densities, and internal forces which satisfy the minimum weight design. These results provide the appropriate mass to the experimental data and allow substantial changes in size, shape, and topology.


Cu-rich CuInSe2 is known to phase segregate into a surface phase of CuxSe and near-stoichiometric CuInSe2. In both epitaxial CuInSe2 films grown by molecular beam epitaxy as well as in polycrystalline CuInSe2 films, growth under Cu-rich conditions is known to lead to improved crystalline quality with significantly lower concentrations of point and extended defects. To examine details of the interaction of CuxSe and the CuInSe2 matrix, we have grown CuInSe2 films under Cu-rich growth conditions on GaAs(001) substrates by molecular beam epitaxy at 450°C and have investigated the as-grown films by high resolution x-ray diffraction and transmission electron microscopy. In addition the behavior of the CuxSe surface phase under thermal effects has also been investigated.

Public transportation such as a bus is often used to travel to various places in Indonesia. Each bus will only stop at each bus stop transit. However, the bus stop transit in Indonesia, especially at Bandung city, is not friendly to disable person like visually impaired people. In this research, a smart public transportation bus stop transit is designed and implemented, which can inform the identities of the next arrival bus through sound and text display. This research purposed to provide a device which gives a natural movement for the visually impaired in using public transportation and reducing the dependence on other people in doing daily activities in their lives. This system is using NRF24L01 as a sender and receiver the data between bus and the bus stop transit. According to the testing result, this system can transmit the information about 30 meters from the bus stop transit. The delay occurs around 2–3 seconds for a single coming bus, and 5–6 seconds to the bus which arrived into the bus stop platform at the same time.


This study is to gain an understanding and develop a test rig for high-rise building isolation for ground motion in vibration and noise phenomenon in Malaysia. In this study a 7-storey high rise building structure with actual scale will be developed. There are three types of simplify structure base such as a pure force, rigid body and short resonant beam. These bases will be connected to the ground structure of building via a single isolator. The outcome of this study is to express the frequency averaging energy transmission or the peak amplitude transmission to the ground structure motion in terms of approximate source and isolator mobility formulae. Theoretical predictions will be compared with experimental measurements. It is useful to predict an energy transmission from ground motion from building, more profound understanding and greater confidence on the approach will not be gained unless measurements can be made. The methods called frequency domain acceleration data and structural frequency response information will be used in this study. These methods are chosen because there is energy input to the structure at a single isolator, and then the energy will be transmitted through an isolator using acceleration at the top and bottom. The energy then will be absorbed by finite resonant structure using accelerations at one, two or four points. By right, after completing this study and experiment, the response on ground isolator of high-rise building can be understood in depth.


Bismuth molybdate (Bi2MoO6) nano-particles (NPs) were synthesized using bismuth nitrate, ammonium molybdate, citric acid and ethyl cellulose by a simple sol−gel method. The structure, morphology, opto-magnetic and photocatalytic properties of the obtained powder were characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, high resolution scanning electron microscopy (HRSEM), energy dispersive X-ray (EDX), ultraviolet−visible diffuse reflectance spectra (DRS), photoluminescence (PL) spectra and vibrating sample magnetometer (VSM) techniques. The XRD, FT-IR and EDX results indicate that the resultant powder is pure and single phase crystalline Bi2MoO6 with orthorhombic structure. The HRSEM image shows that the morphology of obtained powder consists with well defined nano-particles structure. The VSM results show superparamagnetic behavior of the obtained nano-particles. The photocatalytic activity of Bi2MoO6 nano-particles was performed. The addition of TiO2 catalyst enhances the photocatalytic activity of Bi2MoO6 nano-particles. The catalysts Bi2MoO6, TiO2 and mixed oxide catalyst Bi2MoO6−TiO2 nano-composites (NCs) were tested for the photocatalytic degradation (PCD) of 4-chlorophenol (4-CP). It is found that the PCD efficiency of Bi2MoO6−TiO2 NCs is higher than that of pure Bi2MoO6 and TiO2 catalysts.


Mitotic and degenerate cell counts were made on the eye and brain of frog tadpoles exposed to three different doses of α rays and the results compared with those already known for a small dose of γ rays. Whereas with the lowest α-ray dose the relation between mitosis and degeneration does not differ from that which would be expected to follow a relatively small dose of radiation, after the two larger α-ray doses degeneration far exceeds this amount. It would seem that α rays cause the degeneration of potential dividing cells in considerable numbers.


This article offers an alternative grouping of Latin verbs that is more informative than the traditional four conjugations. By considering the "behavior" of the stem vowel in the present, perfect and supine systems as a coherent unit, four "inflectional profiles" emerge that cut across the conjugations. In the three-part structure of a verb form—a stem plus a tense-mood-aspect marker plus a personal or declensional ending, summarized as S-T-E— the main grammatical "action" takes place in the verb stem as it "crosses the border" into the tense markers. 0A few notions of basic phonetics account for whatever changes take place in the stem at that point. The familiar infinitive equipped with a superscript serves as a single "smart" principal part to encapsulate a verb's complete inflection at a glance. This holistic endeavor redefines "regular" to include more of the facts and to highlight useful relationships that textbooks leave unspoken. If one accepts a slight step into abstraction, apparent exceptions and irregularities turn out to be completely regular.


The Λ-Σ0 mixing in neutron star matter is discussed in three theoretical models: the G-matrix theory, the relativistic mean field theory and the QCD sum-rule approach. The mixing of 2~8% at the critical baryon density of Λ appearance(2.3 times of the normal nuclear density) is predicted in the G-matrix theory. The second and third models give smaller mixing, 0.2~1.0% and < 0.25%, respectively. Since the G-matrix theory is the most dynamical model among the three, the mixing of 2~10% at 2~3 times of the normal density may be realistic.

oise sources which are incorporated into built-up assemblies, such as fans, compressors, motors, pumps etc, are clearly responsible for the noise of the assembly but are not the sole factor in the process of noise generation. Two additional signifi cant factors play role in the fi nal noise of the assembly: the way the noise source is implanted into the structure, comprising its orientation, structural and other coupling etc. the way the structure further modifi es the noise input from the source before it reaches the listener's ear. Under the action of noise generating components the assembled structure often amplifies the overall noise. Typical examples of products which generate noise in this way are HVAC installations, household appliances, outdoor machinery, computation equipment etc. In these and similar products noise is transmitted to the surroundings as a direct air-borne noise, structure-borne noise (via feet, supports, etc) and frequently fl uid-borne noise (via ducts, pipes, etc). The latter two noise mechanisms are rarely dealt with in industrial conditions.


School mix and distribution of immigrant students in the italian schools - The way immigrant students are distributed in the Italian schools appears unequal, both at regional and at local level, and also in the single schools and classes. The article reflects upon the consequences of such phenomenon and on the strategies to be carried out in order to prevent the building of "separate classes", mostly attended by students whose citizenship is not Italian. The article takes into account the ways distribution is carried out in several European countries - and in particular the case of the carte scolaire in France -, analising the policies of orientation of enrolments and the risks of school apartheid. For what concerns Italy - where there is a variety of situations because of the liberalisation of accesses - the risk of an unequal distribution and of an -inner segregation- is confirmed, which could be emphasized by special measures in favour of immigrants. Finally, the article introduces the reasons for the school mix and the debate on the consequences of heterogeneity in class, which is linked to a greater equity but not necessarily to a lower scholastic achievement, as long as it is supported by measures of complex instruction, differentiated didactic, intercultural prospective, and a planning at local level based on the pact between school and territory.

In this study, the deterioration of a reinforced concrete structure due to alkali-aggregate reaction was estimated by using ultrasonic methods. Tests were carried out for concrete with reactive bronzite andesite crushed stone and total equivalent na2o of 6 kg/m3. The specimens were cured in the chamber with 40 deg c and 100% relative humidity for two months after the age of 14 days. The pulse velocity was measured during the accelerating curing period, and after the age of 10 months, the spectral analysis of ultrasonic pulse waves transmitted through concrete was applied to estimate the deterioration. The pulse velocity of test specimens decreased abruptly with compressive strength and modulus of elasticity because of deterioration due to the reaction. On the other hand, the velocity of concrete core slightly decreased due to the residual expansion after sampling the core, and then it increased to more than the velocity of the test specimen because the silicate gel formed by the reaction may be filled in the cracks. It is easy to estimate the deterioration due to the reaction by the ultrasonic pulse velocity method and the spectral analysis of ultrasonic pulse waves transmitted through concrete proposed in this study.(a) for the covering abstract of the conference see IRRD 811982.


Polypyrrole (PPY) microbelts are synthesized via the absorbent cotton template for the first time. PPY microbelts are characterized by Fourier transform infrared spectroscopy. The stability, the morphology and electrical conductivity of such microbelts are evaluated by means of scanning electron microscope, thermo-gravimetric analysis and four-probe conductivity. A possible mechanism for the formation of PPY microbelts are proposed. The conductivity is measured, and the conductivity variation mechanism of the PPY microbelts with the pyrrole monomer concentrations is analyzed.

Sport is a natural medium for bringing together people of different backgrounds throughout the world. If grounded in ethics and if participants follow the rules and cooperate, sport can be a conduit for world harmony (Sport great for human bonding, 2010).As international relationships are developed through sport, those relationships can help support larger global endeavors in pursuit of a better world. If international sport based relationships are grounded in Mill's utilitarianism that calls for actions resulting in the most long-term happiness for the most amount of people (Mill, 1863/1969) those relationships are well positioned to transition to the domain of governmental politics, where meaningful attempts to resolve large world issues can be addressed, under the same utilitarian premise. In pursuit of a better world, identifying common groundamong the many differences held by people throughout the world is a magnanimous challenge. Beauchamp's (1982) practical suggestion that common sense, habits, and past experience are most helpful when attempting to select actions that will determine long-term happiness. Moving beyond sport and transferring the application of Beauchamp's practical utilitarian approach to larger global conflicts, can help guide governments as they engage in the necessary politics, to move toward improving global problems in the interest of world harmony.

In conclusion, the animated video of the LCM instructional materials is very valid and practical.


Nitrites concentration and activity of peroxide oxidation of lipids (POL) in erythrocytes of healthy males of different age groups have been studied. Minimal concentration of nitrites in erythrocytes has been detected in 22-35 y.o. age group. With age growing (30-50 y.o. age group), nitrites concentration increases and stabilizes. Maximal concentration of POL products has been detected for males of age 22-35, minimal one of age 44-50. Additional study of activity of superoxyddismutaze allowed assuming presence of latent deficiency of antioxidant protection in erythrocytes of persons of 36-50 y.o.


We report an unusual in-field behaviour of
SrEr_22O_44
for a magnetic field applied along two high-symmetry directions, the a
and c axes. This geometrically frustrated magnet hosts two
crystallographically inequivalent Er ions, Er1 and Er2, that are both
located on triangular zigzag ladders, but only one site, Er1, forms a
long-range magnetic order at low temperatures in a zero field. We follow
the sequence of peculiar field induced states in
SrEr_22O_44
with detailed single-crystal magnetisation and neutron diffraction
experiments. On application of an external field along the
cc axis,
the long-range antiferromagnetic order of the Er1 ions is rapidly
destroyed and replaced, in fields between 2 and 5 kOe, by a state with
shorter-range correlations. The change in correlation length coincides
with a fast increase in magnetisation during the metamagnetic transition
above which a long-range order is reestablished and maintained into the
high fields. The high-field ferromagnet-like order is characterised by
significantly different magnetic moments on the two Er sites, with the
Er1 site dominating the magnetisation process. For the field applied
parallel to the a axis, in the field range of 4 to 12 kOe, the planes of
diffuse magnetic scattering observed in zero field due to the
one-dimensional correlations between the Er2 moments are replaced by
much more localised but still diffuse features corresponding to the
establishment of an up-up-down structure associated with a one-third
magnetisation plateau. Above 14 kOe, a ferromagnet-like high-field order
is induced following another phase transition.
For this direction of the field, the Er2 moments dictate the succession
of transitions while the Er1 moments remain significantly less
polarised. A complete field polarisation of both Er sites is not
achieved even at 50~kOe for either field direction, reflecting the
strongly anisotropic nature of magnetisation process in
SrEr_22O_44.

The present invention provides an apparatus and a method for highly reliable data communication with simplified construction.


The common approaches to sample a signal generally follow the well-known Nyquist-Shannon's theorem: the sampling rate must be at least twice the maximum frequency presented in the signal. A new emerging fleld, compressed sampling (CS), has made a paradigmatic step to sample a signal with much less measurements than those required by the Nyquist-Shannon's theorem when the unknown signal is sparse or compressible in some frame. We call a compressed-sampling fllter (CSF) one for which the function relating the input signal to the output signal is pseudo- random. Motivated by the theory of random convolution proposed by Romberg (for convenience, called the Romberg's theory) and the fact that the signal in complex electromagnetic environment may be spread out due to the rich multi-scattering efiect, two CSFs via microwave circuit to enable signal acquisition with sub-Nyquist sampling have been constructed, tested and analyzed. Afterwards, the CSF based on surface acoustic wave (SAW) structure has also been proposed and examined by the numerical simulation. The results have empirically shown that by the proposed architectures the S-sparse n- dimensional signal can be exactly reconstructed with O(S logn) real- valued measurements or O(S log(n=S)) complex-valued measurements with overwhelming probability.


The dependence on polarization of the performance of a microfiber coupler based temperature sensor is experimentally investigated. The optical microfiber coupler based temperature sensor has a diameter circa 2 μm and can sense temperature in the range from 100°C to 1000°C, with an average sensitivity of 18.9 pm/°C. It is shown that different polarization states of the input signal have a significant influence on the proposed temperature sensing accuracy, with an estimated peak error of 63°C at 1000°C.


Respirometric mineralization studies of 2,4,6-trinitrotoluene (TNT) were conducted with microorganisms isolated from a site contaminated with munitions waste in Illinois. Nine aerobic bacterial species were isolated under a carbon- and nitrogen-limited condition and tentatively identified as: one Pseudomonas species; one Enterobacter species; and seven Alcaligenes species. Experiments were performed using each of the nine organisms individually and with a consortium of all nine bacterial species. The aerobic microorganisms were cultured in a sterile nutrient solution with glucose and 20 mg/L TNT. Mineralization was determined using uniformly ring-labeled {sup 14}C-TNT in a respirometer that trapped the evolved CO{sub 2}. Biodegradation behavior was characterized based on oxygen consumption, distribution of {sup 14}C activity, and high-performance liquid chromatography (HPLC) analysis of TNT and its transformation products.


Spaceborne profiling lidar missions such as the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) are collecting direct elevation measurements, supporting the retrieval of vegetation attributes such as canopy height that are crucial in forest carbon and ecological studies. However, such profiling lidar systems collect observations along predefined ground tracks which limit the spatially complete mapping of forest canopy height. We demonstrate that the fusion of ICESat-2 along-track canopy height estimates and ancillary Landsat and LANDFIRE (Landscape Fire and Resource Management Planning Tools Project) data can enable the generation of spatially complete canopy height data at a regional level in the United States. We developed gradient-boosted regression models relating canopy heights with ancillary data values and used them to predict canopy height in unobserved locations at a 30 m spatial resolution. Model performance varied (R2 = 0.44 − 0.50, MAE = 2.61–2.80 m) when individual (per month) Landsat data and LANDFIRE data were used. Improved performance was observed when combined Landsat and LANDFIRE data were used (R2 = 0.69, MAE = 2.09 m). We produced a gridded canopy height product over our study area in eastern Texas, which agreed moderately (R2 = 0.46, MAE = 4.38 m) with independent airborne lidar-derived canopy heights. Further, we conducted a comparative assessment with the Global Forest Canopy Height product, an existing 30 m spatial resolution canopy height product generated using GEDI (Global Ecosystem Dynamics Investigation) canopy height and multitemporal Landsat data. In general, our product showed better agreement with airborne lidar heights than the global dataset (R2 = 0.19 MAE = 5.83 m). Major differences in canopy height values between the two products are attributed to land cover changes, height metrics used (98th in this study vs 95th percentile), and the inherent differences in lidar sampling and their geolocation uncertainties between ICESat-2 and GEDI. On the whole, our integration of ICESat-2 data with ancillary datasets was effective for spatially complete canopy height mapping. For better modeling performance, we recommend the careful selection of ICESat-2 datasets to remove erroneous data and applying a series of Landsat data to account for phenological changes. The canopy height product provides a valuable spatially detailed and synoptic view of canopy heights over the study area, which would support various forestry and ecological assessments at an enhanced 30 Landsat spatial resolution.

The ability to accurately estimate end-to-end network latencies is extremely important for many services, from overlay network formation to Edge computing and 5G. Research in Network Coordinate Systems (NCS) has over the years focused on providing such estimates while conserving network resources by avoiding excessive probing. However, Internet latencies are inherently unstable and estimates produced by existing NCS's are shown to quickly become obsolete. In this paper, we devise TSMF, a novel NCS method based on an ensemble of Time-Series Forecasting and Matrix Factorization (MF). Fusing the two approaches results in a model that takes advantage of the low-rank structure of end-to-end latencies and temporal correlations with past measurements. In addition, TSMF can forecast future end-to-end latencies which has been impossible using existing NCS approaches. Our results demonstrate that TSMF outperforms Euclidean and MF-based NCS's with up to 6× less relative error in predicting end-to-end latencies. We also demonstrate the accuracy of TSMF in forecasting future end-to-end latencies, and its consequent suitability for services such as web-service recommendation.


The objective of this study was to evaluate the applicability of a HSPF (Hydrological Simulation Program-Fortran) model for runoff estimation in the Namgang dam watershed. Spatial data, such as watershed, stream, land use, and a digital elevation map, were used as input for the HSPF model, which was calibrated and validated using observed runoff data from 2004 to 2015 for three stations (Sancheong, Shinan, Changchon) in the study watershed. Parameters for runoff calibration were selected based on the user's manual and references, and parameter calibration was done by trial and error. The R2 (determination coefficient), RMSE (root-mean-square error), NSE (Nash-Sutcliffe efficiency coefficient), and RMAE (relative mean absolute error) were used to evaluate the model's performance. Calibration and validation results showed that annual mean runoff was within a ±5 % error in Sancheong and Shinan, whereas there was a14% error in Changchon. The model performance criteria for calibration and validation showed that R2 ranged from 0.80 to 0.92, RMSE was 2.33 to 2.39 mm/day, NSE was 0.71 to 0.85, and RMAE was 0.37 to 0.57 mm/day for daily runoff. Visual inspection showed that the simulated daily flow, monthly flow, and flow exceedance graph agreed well with observations for the Sancheong and Shinan stations, whereas the simulated flow was higher than observed at the Changchon station.


Complete high-speed quantum key distribution (QKD) systems over fiber networks for campus and metro areas have been developed at NIST. The systems include an 850-nm QKD system for a campus network, a 1310-nm QKD system for metro networks, and a 3-user QKD network and network manager. In this paper we describe the key techniques used to implement these systems, including polarization recovery, noise reduction, frequency up-conversion detection based on PPLN waveguide, custom high-speed data handling and network management. A QKD-secured video surveillance system has been used to experimentally demonstrate these systems.


The urban population in India is projected to grow faster than its overall population by 2030. This rapid increase in population will create pressure on the economy as well as on the education system. With the changing time, psychology of students is also changing. Today, attending hours of face-to-face lectures in schools/colleges in today's dynamic scenario is passe. And this can be suspected as a major reason of dropouts Government schools. Time has come. Teaching needs to be changed. There is a growing need for teachers to make their classes more dynamic as to suit the demand of today's youth. Another problem which is faced in Indian education system is the shortage of education institutes and faculty. This limitation can be overcome if the learning resources can be provided on cloud and the relevant technology can be made accessible to everyone. Technology, therefore has the capability to address all these issues. Prime Minister Narendra Modi's emphasis on the Digital India campaign aims to ensure better connectivity and maximize the potential of India's youth. Growing penetration of internet and increasing smartphone penetration along with a strong thrust from the Government are accelerating the transformation of India's education system. World is being digitized and therefore, the need of the hour is to make the youth of today, technology friendly. The key to success is in catching them young. In this paper, factors affecting the e-learning quality for Management students of Delhi NCR also derived. The exploratory factor analysis was conducted and five critical factors for the successful implementation of e-learning for management students were derived. These five critical factors were termed as Utilitarian factors, Facilitating conditions, Progress tracking, Content quality and Hedonic factors.


The paper presents the results of the study of applicability of time-frequency correlation functions to solving the problems of internal combustion engine fault diagnostics. The proposed methods are theoretically justified and experimentally tested. In particular, the method's applicability is illustrated by the example of specially generated signals that simulate the vibration of an engine both during the normal operation and in the case of a malfunction in the system supplying fuel to the cylinders. This method was confirmed during an experiment with an automobile internal combustion engine. The study offers the main findings of the simulation and the experiment and highlights certain characteristic features of time-frequency autocorrelation functions that allow one to identify malfunctions in an engine's cylinder. The possibility in principle of using time-frequency correlation functions in function testing of the internal combustion engine is demonstrated. The paper's conclusion proposes further research directions including the application of the method to diagnosing automobile gearboxes.


Self-governing rule is an inevitable choice to fulfill the multi-layered social governance under the circumstance of civil society separating from political country,and all the self-governing rules,whether it's from autonomy of private law or empowered by public law,can inflict civil harm both on the inner members and outsiders of the self-governing organization.The collating of the tort cases published by the Supreme Court of China indicates that courts usually take the disobedience of self-governing rule as fault of the defendants in tort adjudications,which means self-governing rule is to some extent related to duty of care,furthermore the application of self-governing rule enlarges the protection range of tort law in the absence of positive legal regulations.


This is an article in two parts. Part i offers a new way of looking at progressivism and progressive politics by defining different typologies of progressivism and by looking for these approaches in the cultural strategies of specific ethnic groups. The study offers a theory of how these progressive cultural strategies are maintained and distinguishes these strategies from apparent "progress" that may simply be a phenomenon of temporary accommodation of different ethnic groups in more complex systems. Part ii examines the ideology of "progress" as part of the cultural strategy of Jews and whether this strategy, which appears stronger when Jews are minorities in the Diaspora, is consistent with Jewish culture once Jews have a territorial boundary where they are a "majority." This article touches upon the political choices that Jewish "political progressives" and Jews, overall, have made recently in the U.S.; modifying their support for "progress" in return for political representation, with parallels to the historical situations of other minorities. While "identity based" political choice that slows the overall "progress" of civilization appears to have protected Jewish interests in the short term, historical comparisons suggest that this choice will endanger Jews if the U.S. economy and U.S. global influence collapse, in a direct historical parallel to the European Holocaust; offering an opportunity to test theories on how (and whether) "progress" occurs. In short, this study examines the choice that Jews made in the 20th century to define themselves as "European" rather than "Middle Eastern" (or "Eastern") and how a rethinking of this choice could be fundamental to protecting Jews in Israel and to restarting a global impetus for both social and political "progress."


Measurements at IPPE (Obninsk) i) Prompt fission-neutron spectra for U have been measured early at incident neutron energies 3, 5, 7, 13, and 14.7. Similar measurements were recently performed at energies 16 and 18 MeV. Dependence of the average fission-neutron energy on the excitation energy of fissioning nucleus was estimated (Fig. 1). The values of average energies do not exceed 2.05 MeV at highest energies of incident neutrons and their saw-like changes are strongly correlated with a step-like structure of the fission cross sections. ii) Total and relative group yields of delayed neutrons, as well as the corresponding group half-life times were measured for U at the incident neutron energies from 1 to 18 MeV and for U and Pu at energies between 14 and 18 MeV. Evaluations were made for the energy dependence of delayed-neutron yields for U, U, Np,and Pu. It is shown that the average half-life times of delayed neutrons essentially differ in the energy region 14-18 MeV from evaluations included in current data libraries (Fig. 2). The energy dependence of group half-life times of delayed neutrons was also measured for Am at the incident neutron energy region between 0.75 and 5 MeV. iii) The leakage neutron spectra from thick vanadium, lead and bismuth spheres were measured for 14 MeV neutrons and the Cf(sf) neutron source. The spectra obtained are used now for testing the corresponding neutron data files. iv) Preliminary measurements of the fission cross sections at the region of unresolved resonances were performed for Th, U, Np, Pu, and Cm on the basis of the new lead-slowing-down spectrometer at the Institute of Nuclear Research RAN (Troitsk). The planned future measurements should essentially reduce uncertainties of experimental data on the fission cross sections of minor actinides at the region of unresolved resonances. v) The transmission and self-indication functions were measured for Rh, Ho, W, Nb, Mo, Pb, Sn, In, Sm on the IBR spectrometer (JINR, Dubna) at neutron energies between 0.01 and 100 keV. The total neutron cross-sections and resonance shielding effects are estimated and compared with the current data-library evaluations.


BACKGROUND
Endoscopy provides valuable diagnostic informationand intervention therapies for gastroenterologists. Therefore, various drugs have been used to induce sedation in patients undergoing endoscopy, whereas none have been considered definitely preferred by endoscopists. In the current study, we decided to use the combination of magnesium sulfate, ketamine, and their synergistic effects for creating partial analgesia to increase the satisfaction of endoscopists and patients.

METHODS
This study is a Double-Blind Randomized Clinical Trial that investigates the sedative effect of ketamine, magnesium sulfate, and propofol in endoscopy. Patients were selected from individuals over 12 years old and with American Society of Anesthesia (ASA) physical status I or II. The study was performed on 210 patients classified as ASA (I have no underlying disease) or II (with underlying controlled disease). The whole group was relieved of pain during injection, sedation according to Ramsay criteria, satisfaction with the operation, duration, recovery, nausea and vomiting, hypotension, and decreased oxygen saturation were compared.

RESULTS
A total of 155 patients were enrolled in our study, including 51 patients (midazolam and propofol), 55 patients (midazolam and ketamine), and 49 patients (midazolam and ketamine and magnesium). The results showed that preoperative heart rate, intraoperative systolic blood pressure, intraoperative diastolic blood pressure, postoperative heart rate, postoperative systolic blood pressure, and postoperative heart rate were significantly different between the groups.

CONCLUSION
The satisfaction of the endoscopic was achieved to a great extent, mainly in the group receiving midazolam and propofol and in the group receiving midazolam and ketamine. In most cases, the satisfaction of the endoscopic was acceptable, and the low satisfaction of the endoscopic was more in the group receiving midazolam. Ketamine and magnesium were observed. The two compounds midazolam-ketamine, and midazolam-propofol, have a more favorable effect than the combination of midazolam, ketamine, and magnesium.


At present, there is an increase in publications of various geographical atlases: national atlases, atlases of macroregions and administrative-territorial formations of a general geographical, thematic and integrated nature are being developed and published.

Specialists from Volga State University of Technology developed a comprehensive ecological and geographical atlas of the region for the Mari El Republic for the first time. An electronic version is available on the Internet.

The article is devoted to the development algorithm, methodological approaches and content of the Ecological and Geographical Atlas of the Mari El Republic. The atlas includes 6 sections and 119 thematic maps and corresponds to the experience of Russian and foreign mapping. The first section provides a brief description of the physical and geographical position of the republic. Further, there are information on natural resources and conditions (geology, topography, climate, surface and groundwater, vegetation and soil cover, wildlife and landscapes), history of the development of the territory, location and demographic indicators of the population, social infrastructure, territorial structure of the distribution of industries (mechanical engineering, chemical and light industry, construction, agro-industrial and timber industry, transport infrastructure). The final section summarizes information on the use of environmental monitoring components (minerals, groundwater and surface water, soil cover, atmospheric air, and forest vegetation).

The sources for creating the Atlas were stock, literary, cartographic, and statistical and monitoring materials from scientific institutions, universities, executive authorities of the subject of the Russian Federation, as well as the results of own research by the development team.

The publication is intended for a wide range of readers and can be used in of managerial, economic, scientific and educational activities.


A multi-core cluster is a cluster composed of numbers of nodes where each node has a number of processors, each with more than one core within each single chip. Cluster nodes are connected via an interconnection network. Multi-cored processors are able to achieve higher performance without driving up power consumption and heat, which is the main concern in a single-core processor. A general problem in the network arises from the fact that multiple messages can be in transit at the same time on the same network links. This paper considers the communication latencies of a multi-core multi-cluster architecture will be investigated using simulation experiments and measurements under various working conditions


Effective internal control over financial reporting (ICFR) should either prevent or enable correction of any material misstatement in a firm's financial statements. Independent auditors, guided by professional standards, prepare an ICFR audit report, which provides a gauge by which the public can evaluate the reliability of a firm's financial information. A firm manager may be tempted to misstate financial statements if he/she perceives a substantial reward for doing so. This study examines whether managers and firms are rewarded for misstating their financial statements in situations where there are incentives to do so, specifically, when an industry-leading peer is fraudulently inflating its reported earnings. The authors test to see if managers experience an increase in compensation as a result of misstatement. The authors also test to see if their firms benefit from misstating via changes to their cost of capital. Results suggest that neither managers nor their firms benefit from managing earnings by misstating financial statements. These findings are important, because a manager who ex ante understands that misstating will not lead to benefits personally or his/her firm is less likely to misstate in the first place.


Henri sauvage starts in "art nouveau" by creating pochoirs, but he rises to fame by participating in the world's fair of 1900 in paris and after the design of the majorelle's villa in nancy (1898-1902). With his associate charles sarazin, henri sauvage designs six low cost housings between 1903 and the world war i. In collaboration with paul sarzin, the two architects design at the same period two villas in biarritz, six hotels and several real estate operations. Invented in 1909, patented in 1912, the stepped-terrace construction system is applied at the luxurious appartment building of 26 rue vavin in paris (1912-1913), at the low cost housings of 13 rue des amiraux in paris (1913-1928) and of rue des saules (1925-1928; non constructed). Since 1913, henri sauvage works on the principe of quick construction for which he registers many patents. The necessity of construction site planing lays down, in the twenties, the design and construction of parisian appartment buildings, the reconstruction of the samaritaine department stores in paris (1925-1930) and the construction of the decre department store in nantes (1931). This thesis is based on the henri sauvage archive (institut francais d'architecture) and on the building licence files (archives de paris), that allowed the constitution of a descriptive catalogue (second part). Here is analysed the distance between the practice of henri sauvage and the propaganda that he elaborated with reference to his researches.

We study in some detail the next-to-minimal supersymmetric standard model with gauge mediation of supersymmetry breaking. We find that it is feasible to spontaneously generate values of the Higgs boson mass parameters {mu} and B{sub {mu}} consistent with radiative electroweak symmetry breaking. The model has a phenomenologically viable particle spectrum. Messenger sneutrinos with a mass in the range 6 to 25 TeV can serve as cold dark matter. It is also possible to evade the cosmological domain wall problem in this scenario. (c) 1999 The American Physical Society.


In industrialized nations, our desire for materialistic items fuels the prominence of sweatshops and subpar working conditions in third-world countries. While sweatshops provide opportunities in places devoid of them, they nonetheless contribute to the lack of advancement in today's youth.


Objective
To explore the preliminary effect of telescopic rod during combined surgical technique for congenital pseudarthrosis of the tibia (CPT) in children.

Methods
A retrospective study was performed for 15 children with Crawford type IV CPT undergoing combined surgical technique and telescopic rod from January 2017 to May 2018. There were 12 boys and 3 girls with an average operative age of 51.6 (16-126) months. The lesions were left (n=7) and right (n=8). The concurrent conditions were proximal tibia dysplasia (n=7) and neurofibromatosis type 1 (n=12). Combined surgical technique and telescopic rod included excision of pseudarthrosis, intramedullary rod insertion, installation of Ilizarov's fixator, tibio-fibular cross union and wrapping autogenic iliac bone graft. The incidence of refracture, ankle valgus, tibial valgus and limb length discrepancy (LLD) were recorded during an average follow-up period of 23.3(12-28) months.

Results
All children achieved primary union. The average primary union time was 4.5(4.0-5.6) months. Nine cases showed LLD with an average extremity length of 1.1(0.5-2.0) cm; ankle valgus (n=1; 18°) and proximal tibial valgus (n=3; 10°, 5° & 6°), telescopic rod displacement (n=6) and epiphyseal plate tethered (n=2). There was no instance of refracture during follow-ups. Movements of ankle joint were all normal with an average dorsiflexion 24°(20°~30°) and with an average plantar flexion 43°(40°~50°) and the function of ankle joint was normal.

Conclusions
The primary healing rate of CPT in children is high by operating with telescopic rod. However, intramedullary rod displacement still occurs.

Fetal pulse oximetry is a promising new technique for intrapartum monitoring. Preliminary results suggest that it is able to reflect fetal oxygenation, and can furthermore detect fetal acidosis because oxygen saturation levels drop as the haemoglobin dissociation curve is shifted to the right. >


Let rho_k, k=1,2,...,m, be the critical Werner state in a bipartite d_k by d_k quantum system, i.e., the one that separates the 1-distillable Werner states from those that are 1-indistillable. We propose a new conjecture (GDC) asserting that the tensor product of rho_k is 1-indistillable. This is much stronger than the familiar conjecture saying that a single critical Werner state is indistillable. We prove that GDC is true for arbitrary m provided that d_k is bigger than 2 for at most one index k. We reformulate GDC as an intriguing inequality for four arbitrary complex hypermatrices of type d_1 x ... x d_m. This hypermatrix inequality is just the special case n=2 of a more general conjecture (CBS conjecture) for 2n arbitrary complex hypermatrices of the same type. Surprisingly, the case n=1 turns out to be quite interesting as it provides hypermatrix generalization of the classical Lagrange identity. We also formulate the integral version of the CBS conjecture and derive the integral version of the hypermatrix Lagrange identity.


Physical puzzles that can be solved with methods for permutation groups are considered and classi ed according to a number of abstract properties. The approach for solution is based on word stabilizer chains (the transversal elements are factored in words in a given list of generators). New methods are presented to construct word stabilizer chains that take advantage of the special structures present in physical puzzles. In many cases the methods are successful in avoiding the exponential growth of word length that plagues stabilizer chain methods to construct transversal elements. Finally, a classi cation scheme for puzzles is presented which helps with nding the permutation group related to the puzzle.


An alternating-direction implicit algorithm is presented for solving the conservative, full-potential equation for unsteady, transonic flow. A new development is the time-linearization of the density function. This linearization reduces the solution process from one of solving a system of two equations at each mesh point to one of solving a single equation. Two sample cases are computed. First, a one-dimensional traveling shock wave is computed and compared with the analytic solution. Second, a two-dimensional case is computed of a flow field that results from a thickening and subsequently thinning airfoil. The resulting flow field, which includes a traveling shock wave, is compared to the flow field obtained from the low-frequency, small-disturbance, transonic equation.


Treatment of BDF1 mice with AdR/dCf combinations (daily x5) leads to acute hepatic dysfunction with accumulative dose related hepatocellular necrosis (Paine et al Cancer Treat. Rep. 65:281-266, 1971). In vivo inhibition of liver S-adenosyl-homocysteine (SAH) hydrolase by AdR is implicated since liver SAH levels increase dramatically following treatment. S-adenosylmethionine (SAM) levels also increase and the SAM:SAH ratios drop from control values of 15 to <1 (Renshaw & Harrap, in Purine Metabolism in Man, Vol. 165B, Plenum Press, pp 363-366, 1984). Further investigations have revealed that while SAH and SAM levels and their ratios normalise following the first 2 days treatment, recovery does not occur thereafter. These data indicate a correlation between the duration of depression of SAM:SAH ratios and the manifestation of hepatocellular necrosis. In addition we have obtained evidence of in vivo inhibition of MT reactions as a result of reduced SAM:SAH ratios: both plasma and urinary creatinine levels are significantly reduced (eg, 23% control urinary creatinine levels by day 5) reflecting inhibition of liver guanidinioacetate MT. Plasma:urinary creatinine ratios do not alter indicating a lack of kidney toxicity in mice. Treated animals also excrete significantly less pseudouridine (<30% from day 2) which may reflect a biochemical lesion at the level of tRNA post-transcriptional modification.
