Extracting Personae Interactive Relation in Chinese Microblog Based on an Improved Dependency Trigram Kernel

As the rapid development of social media, microblog has arrested a lot of attention. However, the automatic information extraction task of the microblog is relatively rare because the microblog text is quite complex and irregular. In this paper, we utilized dependency trigram kernel to construct persons relations extraction model. Firstly, we described the dependency trigram kernel (DTK) for relations extraction. Secondly, we used words semantic similarity tool HowNet to improve semantic similarity of dependency trigram's words. And then we proposed "(POS,GR) (Part of Speech,Grammatical role)" pair to improve dependency trigram's words syntax similarity. Finally, we evaluated the validity of the relation extraction model by experimenting, and the results of experiment show that the F-value of our improved DTK is higher than original DTK for microblog persons relation extraction.
Some distinctive subject contributions from tropical Africa to fundamental science of inland waters

Abstract A short account is given of some features that are unique or extensively developed or intensely studied in tropical African water-bodies, and which are of fundamental limnological significance. They concern the origin and persistence of lakes and rivers; local evolution (endemism) and dispersal of species; cyclic lake stratification in relation to latitude and climate; salinity series and nutrient balance; plankton dynamics; aquatic food chains that are simplified and quantifiable or with major recent change; colonisation of new or transient water bodies by extensively invasive species; and the significance of temperature difference and absolute magnitude as ecological factors.
Application of Waste Plastics for Efficient Flood Protection Systems

There are about twenty different types of plastic resins that are commonly used in packaging applications, whereby five of them are large-volume polymers, i.e. polyethylene (PE), polypropylene (PP), poly(vinyl chloride) (PVC), polystyrene (PS) and poly(ethylene terephthalate) (PET). Together, these polymers account for around 75% of all plastics demand in Europe and is the largest group of waste deposited on Municipal Solid Waste Landfills (MSW). However, waste storage may cause environmental pollution, and the integration of MSW incinerators with materials recovery is one of the most controversial aspects of waste management. In this article a new idea of plastics waste management, based on the production of composite materials with improved properties for flood protection systems, has been presented.

Long food chains are in general chaotic

The question whether chaos exists in nature is much debated. In this paper we prove that chaotic parameter regions exist generically in food chains of length greater than three. While nonchaotic dynamics is also possible, the presence of chaotic parameter regions indicates that chaotic dynamics is likely. We show that the chaotic regions survive even at high exponents of closure. Our results have been obtained using a general food chain model that describes a large class of different food chains. The existence of chaos in models of such generality can be deduced from the presence of certain bifurcations of higher codimension.
Information security risk management and incompatible parts of organization

Purpose: we prepared a questionnaire to evaluate Incompatible parts and also risk management in University of Science and Technology E-Learning Center and studying the Incompatible parts impacts on utility of organization. Design/methodology/approach: By using coalitional game theory we present a new model to recognize the degrees of incompatibility among independent divisions of an organization with dependent security assets. Based on positive and negative interdependencies in the parts, the model provides how the organization can decrease the security risks through non-cooperation rather than cooperation. we implement the proposed model of this paper by analyzing the data which have been provided by questionnaires from different three managers' ideas of Iran University of Science and Technology E-Learning Center located in Iran University of Science and Technology, Tehran, Iran. Findings: In general, by collecting data and analyzing them, the survey showed that Incompatible parts of organizations have negative impacts on utility of organization risk management process. Furthermore, it adds values to other organizations and provides the best practices in planning, developing, implementing and monitoring risk management in organizations. Research limitations/implications: Since Information security and also Risk Management are still areas which need to improve in some Iranian universities, we couldn’t consider them in our analysis. On the other hand, due to questionnaire limitation, the study’s sample size is 1. This size may be considered large for our statistical analysis. Originality/value: The main contribution of this paper is to propose a model for non-cooperation among a number of divisions in a organization and using risk management factors.
Research on PV and battery control system with energy management technology in stand-alone DC micro grid

Abstract. In the DC micro gird control system, it has an important significance for the reliable operation of the system to maintain bus voltage stability and energy distribution. The changing/ discharging control of the battery in different mode is often used to maintain the bus voltage stability. That is, its purpose is to make the PV and the battery storage unit operating in coordination mode and to ensure efficient and stable operation of the DC micro gird. Finally, MATLAB simulations results were provided to validate the effectiveness of the proposed energy storage system control in this paper.
Investigating Cepheid ℓ Carinae's cycle-to-cycle variations via contemporaneous velocimetry and interferometry

Baade-Wesselink-type (BW) techniques enable geometric distance measurements of Cepheid variable stars in the Galaxy and the Magellanic clouds. The leading uncertainties involved concern projection factors required to translate observed radial velocities (RVs) to pulsational velocities and recently discovered modulated variability. We carried out an unprecedented observational campaign involving long-baseline interferometry (VLTI/PIONIER) and spectroscopy (Euler/Coralie) to search for modulated variability in the long-period (P $\sim$ 35.5 d) Cepheid Carinae. We determine highly precise angular diameters from squared visibilities and investigate possible differences between two consecutive maximal diameters, $\Delta_{\rm{max}} \Theta$. We characterize the modulated variability along the line-of-sight using 360 high-precision RVs. Here we report tentative evidence for modulated angular variability and confirm cycle-to-cycle differences of $\ell$ Carinae's RV variability. Two successive maxima yield $\Delta_{\rm{max}} \Theta$ = 13.1 $\pm$ 0.7 (stat.) {\mu}as for uniform disk models and 22.5 $\pm$ 1.4 (stat.) {\mu}as (4% of the total angular variation) for limb-darkened models. By comparing new RVs with 2014 RVs we show modulation to vary in strength. Barring confirmation, our results suggest the optical continuum (traced by interferometry) to be differently affected by modulation than gas motions (traced by spectroscopy). This implies a previously unknown time-dependence of projection factors, which can vary by 5% between consecutive cycles of expansion and contraction. Additional interferometric data are required to confirm modulated angular diameter variations. By understanding the origin of modulated variability and monitoring its long-term behavior, we aim to improve the accuracy of BW distances and further the understanding of stellar pulsations.
PERFORMANCE EVALUATION OF PERMEABLE PAVEMENT AND A BIORETENTION SWALE

SUMMARY The Toronto and Region Conservation Authority is currently evaluating the long term performance and effectiveness of permeable pavement (permeable pavers) and bioretention swales for stormwater management on a parking lot in King City, Ontario. Interim flow monitoring results indicated virtually no surface runoff from the permeable pavement, even during relatively large, high intensity rain events (up to 34 mm). The bioswale overflowed during events with more than approximately 20 mm of rain, but most of the runoff either infiltrated or was released back to the atmosphere through evapotranspiration. Both stormwater practices were extremely effective in reducing peak flows from the parking lot, temporarily storing the runoff and releasing it slowly through the under drains over a period of several days following a storm event. The limited water quality monitoring data collected to date (n=9 events) suggest that infiltration through the permeable pavement and bioswale soils generally results in improved water quality relative to conventional asphalt runoff for several constituents typically found in parking lot runoff. Leaching of nutrients from garden soils beneath the bioswale resulted in elevated levels of these constituents in the infiltrate. Future monitoring of soil chemistry beneath the permeable pavement and bioswale will help determine where stormwater contaminants are being attenuated within the soil profile and how quickly they are migrating through the underlying soils.
Prevalence of opportunistic infections and associated factors among HIV positive patients taking anti-retroviral therapy in DebreMarkos Referral Hospital, Northwest Ethiopia.

Introduction: Opportunistic infections (OIs) are infections that are more frequent or more severe because of immune-suppression in HIV-infected persons, and they are the major clinical manifestation of HIV patients. They indirectly affect the natural history of HIV disease. Many studies concentrated on drug adherence, survival and other aspects of the diseases but limited studies are evident on OIs after Anti-Retroviral Therapy (ART) initiated. So this study was conducted to assess the prevalence of opportunistic infections and associated factors among HIV positive patients taking (ART) in DebreMarkos referral hospital, Northwest Ethiopia. Methods:A cross sectional study design was conducted among HIV patients taking ART from 5 to 7years. The study was conducted in DebreMarkos referral hospital among 423 patients. The data was entered in EPI data version 3.1 and analysis with done by using Statistical Package for Social Sciences (SPSS) version 16.0. Bivariate and multivariate analysis was performed to determine the association of each independent variable with occurrence of OIs. 95% CI and p-value less than 0.05 were considered as significant association. Result: Majority, 241(57%) of the study participants were female patients. The mean age of the study participants was 35.17, with standard deviation of +/- 9.481 years. A total of 181 OIs were observed from the study participants during the study period. The commonest type of OIs were oral candidiasis 50(11.8%), followed by chronic diarrhea for greater than 1 month, 42(9.9%) and tuberculosis, 41(9.7%). The factors associated with OIs were; Age less than 40 years old was protective (AOR=0.47, 95%CI=0.25, 0.90); baseline WHO stages of IIII those who used to chew khat was at risk of developing OI almost five times more likely than those who did not chew (AOR=4.733, 95%CI=1.185, 18.915); patients with good ART adherence were less likely to develop OI compare to their counter parts (AOR=0.163, 95%CI=0.051, 0.522); current hemoglobin level of ≥ 10 g/dl was protective (AOR=0.313, 95%CI=0.162, 0.605); and recent weight of <60 kg (AOR=3.658, 95%CI=1.656, 8.078). Conclusion and recommendation: The prevalence of OIs among HIV patients on ART is still high namely oral candidiasis, pathogens that cause chronic diarrhea and tuberculosis. Education on adherence of medications, and use of prophylactic medications for OIs should be given for HIV patients taking ART. Similar studies should be conducted to identify the relation between substance abuse and OIs in HIV patients taking ART
A Regional Approach to Shore Erosion Control in the State of Maryland

Coastal erosion is one of the most significant problems affecting Maryland's diverse coastal environment. Approximately 31% of Maryland's 7,020-kilometer coastline is experiencing some degree of coastal erosion, resulting in the loss of approximately 1.05 square kilometers of land per year. In January 2000, the Governor's Shore Erosion Task Force recommended development of a Comprehensive Erosion Control Plan for the State of Maryland. The Comprehensive Plan would coordinate erosion control planning and move Maryland away from the project-by-project approach currently used. In order to initiate statewide planning, the Maryland Department of Natural Resources established partnerships with two coastal counties. These partnerships have three concurrent components. First, data will be collected and analyzed for a portion of the county to provide both State and county planners with a clearer understanding of the economic, cultural and environmental costs of both shore erosion and sea level rise on a local basis. Second, erosion control needs and strategies will be examined and prioritized on a countywide basis, which will increase the effectiveness of erosion control activities and aid the county in soliciting federal and state funding. Finally, public outreach will be conducted to increase public understanding and awareness of erosion control issues and solutions. These partnerships will be used as templates for the development of the statewide components of the Maryland Comprehensive Shore Erosion Control Plan, which will assist in planning and prioritizing areas in need of assistance on a statewide basis.
Estrogen and raloxifene in experimental arthritis and osteoporosis

In postmenopausal rheumatoid arthritis (RA), both the estrogen deficiency and the inflammatory disease contribute to the development of generalized osteoporosis. This leads to an increased risk of fracture, with high morbidity and mortality. More than 50% of women with postmenopausal RA suffer from osteoporosis. Hormone replacement therapy (HRT) is used to treat postmenopausal osteoporosis. HRT has also been shown to ameliorate RA, with decreased joint destruction, reduced inflammation, increased bone density and better patient health assessment. Unfortunately, longterm hormonal treatment is associated with severe side effects, and is no longer recommended. The aims of this thesis were to establish a murine model for studies of osteoporosis in postmenopausal RA. To investigate the relative contributions of estrogen deficiency and inflammation to osteoporosis development in arthritic disease. To examine whether treatment with raloxifene, a selective estrogen receptor modulator, would have the same beneficial anti-arthritic and anti-osteoporotic effects as estrogen. Furthermore, we wanted to compare the mechanisms for these effects between estrogen and raloxifene. We found that lack of endogenous estrogen and arthritic disease contributed equally and additively to osteoporosis development in collagen-induced arthritis, a murine model of human RA. Arthritic ovariectomized mice lost 55% of their trabecular bone mineral density (BMD) compared with cycling healthy mice. Raloxifene potently decreased the frequency and severity of arthritis, protected the joints from erosions, and preserved the BMD. These effects were sustained when treatment was given both as prophylaxis and in established disease, and during longterm treatment. Raloxifene down-regulated the expression of TNF! and RANKL mRNA in the spleen. These molecules are important mediators of bone loss after menopause and in RA. In contrast to estrogen, raloxifene did not affect the effector phase of the disease, as demonstrated in collagen-antibody induced arthritis. Many estrogenic effects are mediated via the classical estrogen receptors and binding to the estrogen response elements, which regulate gene transcription. We found that raloxifene activated this pathway at 1/4 of the intensity of estrogen. In conclusion, our results show that estrogen deficiency and inflammation contribute equally to bone loss in arthritis. Furthermore, raloxifene has potent anti-arthritic and anti-osteoporotic effects, and is possibly a valuable addition to conventional treatment of postmenopausal RA.
Macroeconomic Consequences of the Real-Financial Nexus: Imbalances and Spillovers between China and the U.S

Relying on quarterly data since 1998 we estimate, for China and the U.S., small scale econometric models that economize on the number of variables employed and yet are rich enough to provide useful insights about spillover effects between the two countries under different maintained assumptions about the exogeneity of the macroeconomic relationship between them. We conclude that inflation in China responds to credit shocks. Indeed, the monetary transmission mechanism in China resembles that of the U.S. even if the channels through which monetary policy affects their respective economies differ. We also find that the monetary policy stance of the PBOC was helpful in mitigating the impact of the 2008–9 global financial crisis on China's financial conditions. Finally, spillovers from the U.S. to China are significant and originate from both the real and financial sectors of the U.S. economy.
Purification of waste water using Algal species

A novel alternative method for waste water treatment was developed using a special constructed column treatment plant. The microbial mats used for the study are dominated by the algal species like Ulva sp, Cladophora sp and Chlorella sp. Various parameters like Chemical oxygen demand (COD), Biological oxygen demand (BOD) were observed after the treatment process in three phases, free cell process, batch process and continuous flow process. Better results in percentage of reduction were observed with continuous flow process using chlorella sp and the reduction rate was 52.1 (COD) and 50.8(BOD) along with changes in dissolved oxygen (DO) and pH. The results clearly enunciate the potentials of chlorella sp for employing in waste water treatment. This is an innovative, economical and environmentally safe alternative for treating waste water.
Awareness and Significance of Health, Sexual Diseases, Genetic Disorders and Dietetic Issues among Tribal Women of India

ENGLISH/ ABSTRACT (ENGLISH/ ABSTRACT (ENGLISH/ ABSTRACT (ENGLISH/ ANGLAIS India is the second largest concentration of tribal population in the World. Indian tribes constitute around 8.3 percent of nation's total population. There are 635 tribes located in India. Present, health is a prerequisite for human development and is an essential component for the well being of the mankind. India is characterized by the presence of a large number of endogamous castes, tribes and religious communities with several types of marriage practices and the age at which the girl gets married will depended on social values. Tribal people are known to have sexual practices that differ from those of mainstream cultures and a high prevalence of HIV and AIDS have been reported. Lack of data is a constraint when it comes to tracking the health indicators of the tribal population. Tribal communities in general and primitive groups in particular are highly disease prone. Maternal malnutrition which is quite common among the tribal women is also a serious problem, especially for those having quite a few pregnancies too closely spaced, and reflected the complex socio- economic factors that affects their overall situation. Hence, there is an urgency of comprehensive health research among the tribal populations of India.
Waste Heat Revalorization with Electric Generation Based on Fuel Cell

In the following article the joining of a system of electric generation is described with a thermal transformer by absorption (AHT). The electric system is formed by to cell of combustible type PEM in which is entered hydrogen and oxygen to pressures of the same order of magnitude. The heat that is necessary to release of the cell of fuel is given an AHT using the mixture aqueous lithium bromide. The mixture H2O/ LiBr has been selected by its smaller operation generation temperatures to 373 K. The results show the operation coefficient and the cogeneration coefficient in function of the temperature of operation of the cell of fuel (TFC) and the temperature of the surroundings (Tamb). The results show the obtaining of revalorized useful heat and electric power.
