A space operations tradecraft consisting of detect-track-characterize-catalog is insufficient for maintaining Space Situational Awareness (SSA) as space becomes increasingly congested and contested. In this paper, we apply analytical methodology from the Geospatial-Intelligence (GEOINT) community to a key challenge in SSA: predicting where and when a satellite may maneuver in the future. We developed a machine learning approach to probabilistically characterize Patterns of Life (PoL) for geosynchronous (GEO) satellites. PoL are repeatable, predictable behaviors that an object exhibits within a context and is driven by spatio-temporal, relational, environmental and physical constraints. An example of PoL are station-keeping maneuvers in GEO which become generally predictable as the satellite re-positions itself to account for orbital perturbations. In an earlier publication, we demonstrated the ability to probabilistically predict maneuvers of the Galaxy 15 (NORAD ID: 28884) satellite with high confidence eight days in advance of the actual maneuver. Additionally, we were able to detect deviations from expected PoL within hours of the predicted maneuver [6]. This was done with a custom unsupervised machine learning algorithm, the Interval Similarity Model (ISM), which learns repeating intervals of maneuver patterns from unlabeled historical observations and then predicts future maneuvers. In this paper, we introduce a supervised machine learning algorithm that works in conjunction with the ISM to produce a probabilistic distribution of when future maneuvers will occur. The supervised approach uses a Support Vector Machine (SVM) to process the orbit state whereas the ISM processes the temporal intervals between maneuvers and the physics-based characteristics of the maneuvers. This multiple model approach capitalizes on the mathematical strengths of each respective algorithm while incorporating multiple features and inputs. Initial findings indicate that the combined approach can predict 70% of maneuver times within 3 days of a true maneuver time and 22% of maneuver times within 24 hours of a maneuver. We have also been able to detect deviations from expected maneuver patterns up to a week in advance.


WEI Ming Rui chuckles at the notion that thekarst hills in his backyard are considered world wonders. To him, the conical rock formations common to southern China are simply the accustomed backdrop to his whole life. As for world wonders, Wei has no clue. The 45-year-old head of Nongxiang Village in Du'an County, Guangxi Zhuang Autonomous Region is also its most-traveled person, but he has never been more than 30 miles from the house in which he was born and lives to this day.


Using flow cytometry, and available karyological data GC content and average chromosome size were studied in 120 Euroasian grasses of subfamily Pooideae.


The invention provides a steel plate for a high-strength high-toughness low-yield easily-welding structure. The steel plate comprises the following chemical components in percentage by weight: 0.02 to 0.08 percent of C, 0.30 to 0.50 percent of Si, 1.50 to 1.80 percent of Mn, 0.02 to 0.04 percent of Nb, 0.005 to 0.030 percent of Ti, 0.008 to 0.20 percent of Mo, 0.30 to 0.90 percent of Cr, 0.30 to 0.50 percent of Cu, 0.10 to 0.40 percent of Ni, 0.010 to 0.070 percent of Als, and the balance of Fe. The method for manufacturing the steel plate comprises the steps of molten iron pretreatment, rotary furnace smelting, refining, continuous casting and rolling, wherein the steel blank heating temperature before rolling is between 1,050 and 1,220 DEG C, the rolling temperature in a recrystallization area is more than or equal to 1,000DEG C, and the rolling temperature in a non-recrystallization area is between 950 and (Ar3 plus 0 to 100) DEG C; and after rolling, the temperature is held, and the plate blank is subjected to accelerated cooling. The method has the advantages of unnecessary addition of B and V, low cost, short production period, and the obtaining of the bainite plus ferrite structure without complex thermal treatment, and can control the yield of the steel plate below 0.8 under the condition of ensuring high strength, high toughness and good welding property.


We compared the relative abundance and diversity of ciconiiforms at Salt Plains National Wildlife Refuge in 1995 by using two census methods. Both methods revealed that cattle egrets were the most abundant species, with a relative abundance consistent to that observed by other investigators. Our study found that non-intrusive surveys by vehicle may be preferred over surveys by boat when relative abundance determination is the research goal. © 1999 Oklahoma Academy of Science


On August 1, 2007, I returned to Ladakh, the highest altitude plateau region of India, which crosses part of the Himalayas and is situated in the Indian state of Jammu and Kashmir (see Rizvi, 1996), to carry on my ethnographic fieldwork on everyday interactions in a Buddhist monastery by living with monks in the remote monastery of Rizong, participating in their life, and increasingly experiencing my mind as traveling within itself (see also Brummans, 2007). What follows is my poetic account of this continued experience, deriving renewed insights, and again drawing on field notes, diary entries, and several recorded conversations with teachers and monks.


This thesis examines the involvement of women, both working and upper class, in the Colorado Coal Field Strike, 1913-15. First, I will provide a background for the strike including the Industrial Revolution, the rise of big business, and the influx of immigration which shaped the mining towns. Second, I investigate the participation of mining town women and their complex social and political identities. These women fought to improve their domestic goals, not challenge them. Despite this, they understood the need to utilize Colorado's womens' suffrage to get the working class into office. Third, there will be a discussion on the Ludlow Massacre and the nation's reaction to the event. This battle, branded as a " massacre " pushed upper class citizens to protest for the humanitarian treatment of workers and their families. Then, I investigate the actions of more prominent citizens, first those of upper class women in Denver and then the protests of socialist Upton Sinclair. The upper class women of Denver fought politically enforcing their influence in politics and adding credibility to their citizenship and suffrage, which women gained in Colorado in 1893. Finally, implications of the strike are discussed including industrial reform, the participation of working class women in strikes, and the importance of considering women in public relations and political decisions.


There is need for lower cost, more frequent planetary science missions to compliment the 'once a decade' large multidisciplinary missions. The Solar System Exploration Division of NASA's Office of Space Science and Applications has initiated a program of planetary missions using small spacecraft. This program is called Discovery. Conceptual designs of small spacecraft (100 to 500 kg) for potential Discovery missions to near Earth asteroids are summarized. Another class of spacecraft that could be used for Discovery missions are called microspacecraft. Microspacecraft would be compatible with small launch vehicles such as Pegasus. The term 'microspacecraft' is used here for spacecraft concepts whose mass is about 10 kg. A study of a microspacecraft for a mission to near Earth asteroids is also summarized.

This paper presents a robust fixed lag smoother for a class of nonlinear uncertain systems. A unified scheme, which combines a nonlinear robust estimator with a stable fixed lag smoother, is presented to improve the error covariance of the estimation. The robust fixed lag smoother is based on the use of Integral Quadratic Constraints and minimax LQG control. The state estimator uses a copy of the system nonlinearity in the estimator and combines an approximate model of the delayed states to produce a smoothed signal. In order to see the effectiveness of the method, it is applied to a quantum optical phase estimation problem. Results show significant improvement in the error covariance of the estimator using fixed lag smoother in the presence of nonlinear uncertainty.

Scaling of CMOS devices is projected to continue down to the deep sub-100 nm regime. The gate stack (dielectrics-silicon interface, gate dielectrics and gate contact) is arguably the most critical part of the MOSFET. It is widely believed that oxide will be replaced by high K dielectrics when dielectric thickness is 1.5 nm or below due to excessive direct tunneling (DT) gate leakage. In this work, the effects of high K dielectrics and their interactions with poly depletion (PD), mobility, gate DT leakage and channel charge in sub-100 nm CMOS performance and reliability were investigated.


78 PhotonicsViews 1/2021 © 2021 Wiley-VCH GmbH Directed energy deposition (DED) is an open space process of additive manufacturing (AM) technologies. Due to its high deposition rates, DED processes are well suited to produce large components in small quantities or for customer-specific individual production. During the manufacturing process the laser is used to create a melting pool on the substrate and to melt the added powder as well. Welding tracks are manufactured from which the large AM component is built. As powder material steel powders like 316L or aluminum alloys from the 4xxx series with a good weldability are used. The use of high-strength 7xxx aluminum alloys in particular meet the increasing demands for energy-efficient lightweight construction of components. However, 7xxx alloys have a poor weldability, which makes their processing by DED a challenge. In addition to the use of a single powder material in DED-based additive manufacturing, process setup also allows the tailored use of powder mixtures. These material combinations include MMC materials (metal matrix composite), in which a metallic matrix material is reinforced with hard particles. This is done, among other things, for wear protection purposes. DOI: 10.1002/phvs.202100004 Directed Energy Deposition with Aluminum Alloy

Although inclined pile foundations are sometimes used in civil engineering structures, their behavior under seismic loadings is not yet thoroughly understood. This paper presents an experimental work on inclined pile foundations under earthquake loadings. Dynamic centrifuge tests are performed to investigate the influence of inclined piles on the superstructures and to quantify the soil-structure interaction. Some key parameters are analyzed such as the residual bending moment, the total bending moment and the axial forces. It is found that in certain cases inclination plays a beneficial role to the seismic behavior of the pile foundation system and that the presence of inclined piles increases its natural frequency. Comparing to a vertical pile foundation, the residual bending moment envelope curve is different and larger values are observed. This novel experimental work provides significant data to understand the behavior of inclined pile foundations in seismic regions.


Ischemic stroke remains a common and disabling disease with few proven therapies to improve functional outcome.1 Investigating the risks and benefits of those treatments, mainly IV thrombolysis (IVT) and mechanical thrombectomy, must occur under the constraints of a time-limited window of opportunity.2 Clinicians making time-sensitive therapeutic decisions need data that define best practices based on relevant individual characteristics such as preexisting level of disability.


Regional cerebral arterial blood volume (CBVa) and blood flow (CBF) can be quantitatively measured by modulation of tissue and vessel (MOTIVE) signals, enabling separation of tissue signal from blood. Tissue signal is selectively modulated using magnetization transfer (MT) effects. Blood signal is changed either by injection of a contrast agent or by arterial spin labeling (ASL). The measured blood volume represents CBVa because the contribution from venous blood was insignificant in our measurements. Both CBVa and CBF were quantified in isoflurane‐anesthetized rats at 9.4T. CBVa obtained using a contrast agent was 1.1 ± 0.5 and 1.3 ± 0.6 ml/100 g tissue (N = 10) in the cortex and caudate putamen, respectively. The CBVa values determined from ASL data were 1.0 ± 0.3 ml/100 g (N = 10) in both the cortex and the caudate putamen. The match between CBVa values determined by both methods validates the MOTIVE approach. In ASL measurements, the overestimation in calculated CBF values increased with MT saturation levels due to the decreasing contribution from tissue signals, which was confirmed by the elimination of blood with a contrast agent. Using the MOTIVE approach, accurate CBF values can also be obtained. Magn Reson Med 54:333–342, 2005. © 2005 Wiley‐Liss, Inc.

Almost half of students who enter college require some sort of remedial coursework. Further, states are increasingly moving the responsibility of postsecondary remediation away from four-year campuses to two-year institutions. Scholars and policymakers have grappled with best practice for successfully filling in academic gaps and moving students forward, and there is variation both within and between states as to the ways in which remediation is defined, determined, and administered (Perin, 2006). Using a regression discontinuity design, this study seeks to answer the following question on one community college campus: How does placement into remedial services affect student outcomes, in particular, successful completion of an introductory college-level English course? Although this study focuses on a single community college system, the findings have bearing on a wider sector as the developmental placement practices of Harper Community College District are not unlike those implemented by two- and four-year campuses across the country.

The authors report on 3 projects at the National Renewable Energy Laboratory which utilize nonimaging optics with solar concentrations > 10,000 suns. First, the authors summarize a successful demonstration experiment to produce and measure 50,000 suns with an output power approaching 1 kW. The technique used to measure the light incorporated an extractor tip and has important solar thermal implications. Second, they have finalized and modeled the design of a solar concentrator system that can be used to produce fullerenes, a new type of carbon molecule. Finally, the authors have developed a Nd:YAG side-pumped laser that is designed to achieve an output power of > 60 Watts. They discuss the implications and uses of each of these projects.


A lab-designed clinostat and a UV lamp were applied to enhance the synthesis and accumulation of bergenin in the culture of Ardisia crenata Sims.calli.The simulated microgravity significantly increased the bergenin content with a peak amount 1.85 times of that of control.It also hastened the bergenin formation shortening the time to reach its peak in the calli.The exposure of calli to UV at 308 nm during the early stage of the culture benefited the bergenin accumulation.Both treatments appeared to induce varied effects in promoting the bergenin synthesis and accumulation.However,at the same time,they also retarded the callus growth.


Studies of public support for matters of European integration tend either to neglect or inadequately model the role of the mass media. This study investigates how news media content affects public support for the enlargement of the EU. Other influences on support for integration, such as economic evaluations, anti-immigration sentiment, domestic political considerations and cognitive mobilization are accounted for. The study draws on two-wave panel surveys and media content analyses of television news and national newspapers. The results suggest that media coverage of EU affairs matters to change in public opinion about EU enlargement. The effects of the news media, however, are conditional upon the visibility and consistency in tone of the news.

The population used in this study are manufacturing companies listed on the Indonesia Stock Exchange (IDX) for 2019-2021. The analytical method used is SPSS. The results of this study prove that profitability has a negative and significant effect on financial distress, liquidity has a negative and significant effect on financial distress, but capital structure has no effect on financial distress


A Landau theory of the spin-density-wave (SDW) state in chromium alloys is constructed. In this theory the cubic symmetry of the bcc lattice and the symmetry with respect to rotations in spin space of the exchange interaction are manifest in the free-energy expansion. The Landau coefficients are first obtained for a general two-band model as sums over the Matsubara frequencies, then evaluated near the triple point for a simple class of Fermi surfaces. The competition of the various polarization and wave-vector states is studied, and the stable phase of each of the models determined. It is found that for a Fermi surface consisting of two spheres of unequal radii the triple-$\stackrel{\ensuremath{\rightarrow}}{\mathrm{Q}}$ state is the stable one, whereas the single-$\stackrel{\ensuremath{\rightarrow}}{\mathrm{Q}}$ state is stable for an octahedral Fermi surface. The direction of the wave vector of the SDW is determined, for the octahedral model, to be in one of the $〈100〉$ directions, in agreement with the experimental result for pure chromium.


The sequential parallel design has been proposed to improve the efficiency of clinical trials in psychiatry. The design randomizes patients into three treatment groups. Each group has two phases. The three groups are (1) placebo in the first phase followed by placebo in the second phase, (2) placebo in the first phase followed by drug in the second phase, and (3) drug in the first phase followed by drug in the second phase. We consider the case of binary response data. The analysis of data in the second phase of the trial is restricted to placebo patients who failed to respond in the first phase of the trial. A crucial element in the choice of test statistics is the underlying assumptions of treatment effect in the two phases of the trial. We develop various likelihood-based statistics when the treatment effect is different in the two phases and for the special case in which the treatment effect is equal in the two phases. These statistics are compared in simulation studies to determine their underlying null and nonnull behavior. The score test under the assumption of equal treatment effects is seen to have advantages in terms of Type I error and robustness to assumptions.


In this paper,Gd2O3∶Sm3+ and Ag+-doped Gd2O3∶Sm3+ nanocrystals were prepared by a combustion method.Both Gd2O3∶Sm3+ and Ag+-doped Gd2O3∶Sm3+ nanocrystals appeared to be cubic crystalline phase according to the XRD results.When excited at 275 nm,Gd2O3∶Sm3+ and Ag+-doped Gd2O3∶Sm3+ nanocrystals exhibit similar emission spectra,which consists of the characteristic emission bands of the Sm3+ ions(4G5/2→6HJ,J=5/2,7/2,9/2 transitions at 560,602,650 nm in the spectra) due to an efficient energy transfer from the Gd2O3 host lattice to the doped Sm3+ ions.It was found that the incorporation of the Ag+ ions into the Gd2O3∶Sm3+ nanocrystals has greatly enhanced the photoluminescence intensity of Sm3+ ions in photoluminescence.


The range of foods available to individuals with particular medical conditions e.g. inborn errors of metabolism (Phenylketonuria, PKU) or severe cow's milk protein allergy (CMPA) is so limited that they must rely on specially formulated products to meet their nutrition requirements. Patients with PKU or CMPA have dietary restrictions along with exclusive or partial replacement with special formulations. Artificial sweeteners are used to improve the appearance and palatability of these formulations. Young children have a higher risk of exceeding acceptable daily intakes (ADI) for additives than adults due to higher food intakes per kg body weight 2, . The aim was to use dietary exposure modelling to estimate the intake of artificial sweeteners by young PKU and CMPA patients (1–3 years). To date, none of the exposure models available have addressed additive intakes in young patients. EFSA's recently launched Food Additives Intake Model is not equipped to assess partial dietary replacement with special formulations. A new approach is needed. Food consumption data for patients are not readily available. Data used for analysis are derived from the food consumption survey data of healthy young children as a baseline. The National Preschool and Nutrition Survey (NPNS) was designed to assess the diet, nutrient intake and nutritional status of the healthy Irish children aged 1–4 years. The population of interest was young children aged from 1–3 years (376 subjects). The food groups used for data collection in this study are the 17 EU food categories. An adapted validated probabilistic model was used to assess patients' exposure to artificial sweeteners 5, . Specially formulated products were included in the exposure model to replace restricted foods. Inclusion was based on recommendations for adequate protein intake and dietary adherence data. The exposure assessment results indicate young Irish patients with PKU and CMPA have higher relative average intakes of artificial sweeteners than healthy young children (see tables).


ABSTRACT Bihar, in the central Gangetic Basin, is simultaneously India's poorest and most flood-prone State. Climate change models currently identify a heightening of Bihar's flood risk, as rainfall patterns become more intense and Himalayan glaciers recede. During the past half century, the major strategy deployed by the State and national governments to address the risk of floods has involved the construction of embankments: raised areas of land that seek to control river flow and provide temporary sanctuaries for flood-affected populations. In this article, qualitative data from interviews with flood-affected villagers and policy makers at local, district and State levels are used to assess the social implications of embankments as an adaptive response to flood risk. Evidence from these testimonies leads us to conceptualise embankments as contributing to recursive cycles of vulnerability, in which women, children and poorer social segments have been unwitting bearers. Hence, reliance on embankments is a maladaptation that perpetuates, if not exacerbates, the severe manifestations of social and economic inequality that continue to plague rural Bihar. Perhaps not surprisingly, the voices of those whose lives have been made more difficult by embankments are heard all too infrequently in policy debates. This emphasises the need for climate adaptation initiatives to be anchored in a sustainable livelihood approach, for which the prime analytical objective is to understand the factors that enable or constrain the abilities of people, especially those who are most vulnerable, to make decisions about their lives.


Prochlorococcus is the most ubiquitous and important picocyanobacteria and the smallest photosynthetic organism of oligotrophic marine environments. It has an important ecological function as major contributor to primary production and carbon cycle. Although ecology of Prochlorococcus has been extensively studied in different oceanic regions, little is known about its microdiversity in the oligotrophic Adriatic Sea. For that purpose winter BIOTA cruise (February/March 2015) was conducted in the Southern Adriatic Pit. Genetic diversity and distribution patterns of different Prochlorococcus ecotypes were investigated by molecular tools. Phylogenetic diversity based on clone libraries of the 16S-23S ribosomal DNA Internal Transcribed Spacer (ITS) region indicated presence of 2 different Prochlorococcus populations: high light (HL) ecotype (highest homology to P. marinus MED4/clade HLI) and low light (LL) ecotype (highest homology to P. marinus NATL1A, NATL2A/clade HLI). In addition, Prochlorococcus ecotypes overlapped with rich Synechococcus community and specific sequences showed homology (94-100%) to several uncultured cyanobacteria. As expected dominant Prochlorococcus ecotype was HLI, a clade typical for Mediterranean Sea, followed by less abundant LLI clade. Overall, Prochlorococcus ecotypes have shown to occupy certain depths with overlapping light niches suggesting their horizontal homogenization in the Southern Adriatic Pit.


A photovoltaic (PV) microinverter converts the dc from a PV panel to ac directly, which has the advantages of improved energy harvesting, friendly "plug-and-play" operation, enhanced flexibility/expandability, excellent system redundancy, and no dc cabling/safety issue; therefore, it is an attractive solution for the grid-connected PV system. In ac PV module applications, the features such as power density, reliability, efficiency, and reactive power capability are essential for the microinverters. In order to overcome the drawbacks of the conventional microinverters, including the power density/reliability issues caused by the bulky input capacitors and the limited output reactive power capability, a three-phase microinverter without energy storage capacitors is proposed in this paper. The proposed microinverter consists of a flyback stage, a third-harmonic injection circuit, and a line-commutated current-source-type inverter. The flyback stage realizes maximum power point tracking, while the third-harmonic injection circuit is responsible for output power factor correction. In addition to having the potential of achieving compact structure, long lifetime, and high efficiency, the developed microinverter provides extended output reactive power control range and three-phase balanced output. Finally, the proposed topology and the method are verified by simulations and experimental results.


Four studies describing the development and application of a simple multiplicative probability model for human error prediction are reviewed and evaluated. The methodology is an elementaristic one that requires analysis of system operations to the task-element level. Estimates of human performance reliability are applied through the use of the Data Store, which is based on extrapolation of results from 164 experimental studies. The various possibilities of operator action are explored in detail through a "probability" tree; each branch of the tree represents an alternative contingency. Performance reliabilities for task elements are progressively combined through the use of the series product rule to yield reliability estimates for tasks, mission phases, and the overall system. The methodology has been applied in two contexts: the generation of reliability estimates through a computerized Monte Carlo program and by using experts' rating of operator performance.


Patients' pretreatment preferences can influence outcomes of nonpharmacologic treatments for musculoskeletal pain. Less is known about how patients' treatment preferences change following exposure to treatment.


The aim of this study is to map the special education teachers' (SET) problems in inclusive school. This study used a mixed method research involving 265 SETs as respondents. The variables examined included: (1) SET regulation, (2) SET recruitment process, (3) SET employment status, (4) SET work guidelines, and (5) SET competence. Data were collected using a semi-open questionnaire and a competence scale. The data was analyzed by quantitative and qualitative technique. The results of the study concluded that the existence of SET in inclusive schools still faced problems in terms of regulation, recruitment, employment status, and work guidelines. In addition, the ministerial regulation No. 70 / 2009 about inclusive education has not been implemented optimally in inclusive schools. However, the teachers' competence (pedagogy, professional, personality, social, and special education competence) of SETs in inclusive schools in Indonesia are mostly in good and adequate category. This study suggests that the government immediately organize the regulation of SET to guarantee the existence of SET in the future. Key words: Employment Status, Inclusive School, Recruitment, Regulation, Special Education Teacher, WorkGuideline.


Introduction; Sickle cell anemia (SCA) is a haemoglobinopathy due to single point mutation in the β chain of human haemoglobin. Sickle cell anemia is a form of haemolytic anemia, and it provides the most well documented example of acute and chronic haemolysis, which leads to acute crisis and may develop frequently of infections, and acute chest syndrome. Haptoglobin (Hp) is a unique acute phase protein that primarily scavenges haemoglobin released into circulation by haemolysis. Materials and Methods; Across sectional study was done to determine and compare the frequency of haptoglobin phenotypes among Sudanese patients with sickle cell anemia (SS), and sickle cell trait (AS). A 100 Sudanese patients were recruited in this study after informed consent; and diagnosed by SCA, based on their clinical evaluation, Sickling test, complete blood count (CBC), and Hb electrophoresis. Patient's age was range between 2 to 45 years. An EDTA venous blood was collected from each patient for haptoglobin phenotypes. Hp phenotypes have been performed by PAGE (Poly-acrylamide-gel-electrophoresis) protocol. Results and discussion; To our Knowledge, this study was the first among Sudanese with SCA patients. It appeared that Hp1-1 was taking the high percent (59%) in distribution between the patients. There was high frequency of haptoglobin phenotype 1-1 among

In intelligent space,the main task for home service robot is searching,positioning and delivering the targets(such as cups,medicine,books).The visual servoing method is necessarily needed to finish such tasks.The visual servoing system,which is com-posed of a mobile robot,a 4-DOF manipulator and a camera,is constructed.The kinematic model of the system,along with the calibration of the internal and external parameters of the camera mounted on the manipulator's end effector,is set up.The target's position and pose parameters,which are used to design the position based visual servoing control law,are extracted from homography decomposition method.An object handling experiment is used to validate its validity.The experimental results show that,using this method,the visual servoing tasks for home environment can be finished easily and efficiently.


T o effectively assess the security needs of an organization and to evaluate and choose various security products and policies, the manager responsible for security needs some systematic way of defining the requirements for security and characterizing the approaches to satisfy those requirements. This process is difficult enough in a centralized data processing environment; with the use of localand wide-area networks (LANs and WANs, respectively), the problems are compounded.


Importance Since the late 20 th century, Islamic financial institutions have actively appeared in the financial markets of Europe and America. Banks appear in the United Kingdom, Germany, the USA to offer products based on the norms of Islamic law. The bankers' interest stems from the need to attract customers with moral standards (negative attitude to speculative trading), and the fact that Islamic financial institutions were insignificantly affected by the 2007-2009 global financial crisis. Objectives The study aims to investigate the expansion of Islamic banking products and the demand for them in the global financial market. Methods I collected, processed and analyzed data from statistical reports of Ernst&Young and the International Monetary Fund, and identified the key trends in expansion of Islamic banks and banking products based on the norms of Islamic law. The study also includes an analysis of Islamic banks' assets for 2011-2013. Results The analysis of the market of Islamic banking products shows that most of them are targeted to finance social projects. This leads to an increase in production and improvement of human wellbeing through educational programs, housing construction and other priorities financing. This focus of Islamic banking products is one of the factors of their implementation outside the region of the Islamic model of banking products. Conclusions and Relevance The interest of Western financiers in Islamic banking products contributes not only to the adaptation of the latter to the European model of the financial market, but also leads to an increase in the volume of assets of Islamic banks in the global financial market, which in the future should result in a more stable market environment as compared to the current one.


Objective To understand the mental health status and its influential factors among freshmen in some medical university,in order to provide the evidence for strategies of intervention.Methods University Personality Inventory(UPI) was utilized to examine the mental health status of 2 545 freshmen in some medical university.Univariate analysis and multivariate Logistic regression analysis were employed to explore relative influencing factors.Results The prevalence rates of the mental problem of first type and second type were 5.9% and 24.6%,respectively.There was statistical significance difference between the gender,the economic status,the complete family structure or not,satisfaction to profession or not(P0.05).The results of the multivariable analysis showed that the complete family structure and the social support were the protective factors of the mental health.The poor family economic condition was risk factor.Conclusion It is necessary to adopt the psychological counseling and treatment for the freshmen who have mental problems.Mental health education should be paid attention to in order to improve mental health status of students.


580 Background: Subgroup analyses of the NAPOLI-1 study identified that among patients who were IRI naïve prior to entering the clinical trial, a survival benefit was observed between the study arm and control arm (overall survival (OS): 6.7 months vs 4.2 months). This treatment benefit was not observed among those previously exposed to IRI (OS: 4.6 months in study arm vs 4.8 months in control arm). This study sought to understand the impact of prior exposure to IRI on clinical outcomes among patients treated with liposomal irinotecan in the real-world setting. Methods: This retrospective observational study utilized the Flatiron Health EHR database. Data were analyzed for adult patients with mPDAC treated with liposomal irinotecan -based regimens between January 2016 and October 2020. Patient characteristics, OS and progression-free survival (PFS) were assessed. Prior IRI was defined as IRI given in a prior regimen in the metastatic setting. Cox proportional hazard (PH) methods were used to calculate hazard ratios (HRs). HRs were adjusted to account for demographics and relevant clinical covariates. Patients without prior exposure to IRI were used as the reference population for the Cox PH model (an HR < 1 represents worse survival for unexposed patients relative to the exposed). Results: 675 patients with mPDAC treated with a liposomal irinotecan-based regimen were included. Median age at treatment initiation was 69 (IQR: 62 – 75) years and among patients with available ECOG performance status (PS), 77.4% had a PS of 0-1. 181 (27%) patients were previously exposed to IRI in the metastatic setting (Table). The unadjusted OS HR was 1.3 (95% CI: 1.1 – 1.6, p < 0.001) and the unadjusted PFS HR was 1.4 (95%CI: 1.2 – 1.7, p < 0.001). After adjustment for baseline characteristics the adjusted OS HR was 1.0 (95% CI: 0.8 – 1.3, p = 0.8836) and the adjusted PFS HR was 1.1 (95%: 0.8 – 1.4, p = 0.5626). Conclusions: The results of this study suggest prior exposure to IRI is not a predictor of worse clinical outcomes for patients treated with liposomal irinotecan-based treatment when accounting for key clinical characteristics in a multivariable model. The results from this real-world study can be used to support treatment sequencing decisions for patients with mPDAC following first line therapy. This is the largest real-world evidence study to date of patients with mPDAC treated with liposomal irinotecan.[Table: see text]


Nowadays university hospitals become more and more interested in operations research.
Within a hospital all medical departments are connected by some process.
One of those processes is the care wards provide to patients. While providing this
care, a patient occupies a hospital bed; those beds are scarce. There is a clear tradeoff
between the occupancy level and ward availability. The more beds, the lower the
occupancy and the higher the availability. We describe the idea of increasing the occupancy
while maintaining the same availability, by combining wards. To estimate the
occupancy and ward availability we developed a model that not only uses the patient
arrival rate, but also includes the patient bed requirements (i.e. a patient requiring
multiple beds).


This chapter examines the role that the imagined entity of Asia has played in Australian history. It does so by taking a specific historical moment, namely the glamorous Chinese-American actress Anna May Wong's 1939 visit to Australia, to examine the various meanings of 'Chineseness' in the late 1930s from the perspective of both mainstream Australian society and that of Chinese Australians. Fascination with her visit to Australia was so great that Fox Movietones Australia, mainstream newspapers such as the Sydney Morning Herald, and Australian magazines all covered her visit. Chinese Australians in particular showed great devotion, with fans meeting her when she arrived, writing her letters and demanding her autograph throughout her stay.


Virtual teams are geographically distributed and communicate via computer-mediated communication systems. Trust and relational links among team members have been shown to affect virtual team communications. However, most virtual team members do not receive training on how to effectively promote the development of relational links or trust. This study investigated the effects of both face-to-face relationship development activities and relationship development training on group interactions. Training on relational development in teams was derived from previous literature and administered to 13 selected teams. Twelve teams had initial face-to-face meetings and engaged in face-to-face relationship development activities but received no other training. Twelve additional teams received 'passive' trust development training.


As a result of improved health care and falling mortality rates in the Caribbean area, the proportion of elderly people is increasing. Given the already unbalanced sex ratio in some countries and women's longer (and increasing) life expectancy, women significantly outnumber men at older ages, the disparity increasing as age increases: there are twice as many women as men over 85 years of age. Their physical, emotional, and financial hardships increase with age, and elderly women in the Caribbean represent a class of the new poor


timeseriesdb is an R package which suggests a PostgreSQL database structure to store time series alongside extensive multi-lingual meta information and provides an R database interface including a web based GUI. The timeseriesdb package was designed to handle time series in establishment statistics. Information such as the GDP or data stemming from the aggregation of economic surveys is typically published on a monthly, quarterly or yearly basis. Hence the package is optimized to handle a large amount of dierent time series as opposed to managing a smaller number of high frequency time series such as real time data obtained from measuring devices. The particular focus of timeseriesdb is to help the user nd and extract a particular set of information within a larger set of information. The timeseriesdb package intends to provide the infrastructure for a time series catalog as opposed to handling time series operations on database level. The underlying structure relies on PostgreSQL's hstore data type which allows to store an array of key-value pairs in a single cell. The hstore data type is not only used to reduce the number of records by storing an entire time series in a single record but also to store a record specic amount of multi-lingual meta information items exibly.


Using modern econometric techniques, we show that it is feasible to accurately extract the interest rate from the appreciation of asset prices within the year. On the basis of movements in the price of wheat, we estimate that the interest rate in medieval England was around 12 per cent per annum. This enables us to reject two hypotheses which have featured prominently in the debate on the medieval economy. First, the interest rate is significantly above zero; this runs contrary to the Komlos-Landes view that medieval agents were not economically rational profitmaximisers. Second, the interest rate is significantly below 30 per cent; this undermines the McCloskey-Nash argument that the cost of capital prevented the year-on-year storage of foodstuffs. A discount rate of 12 per cent could also generate output-sharing cooperatives in Kimball's model of farmer behaviour and explain the puzzling pattern of strip scattering in medieval agriculture.


The design of most SCUBA communication equipment requires that the diver/talker speak into a slightly raised air pressure to prevent back flooding at the exhaust port of the system. This study sought to determine the effect on intelligibility of speaking into such an elevated pressure. Three male and two female speakers read standard intelligibility word lists as they wore an oral muzzle adjusted to exhaust release at 0, 1, 2, 4, and 6 cm/H2O re atmospheric pressure. Each talker also read one list into the same microphone and recording system without the constraints of the oral muzzle. Recorded stimuli were played to 20 listeners who identified each word as one of five choices in a closed response set. Results indicated a systematic trend for intelligibility scores to decrease with increases in muzzle release pressures. The effect of donning the oral muzzle itself was to decrease intelligibility by 20%, while scores over all pressures ranged from 14% to 20% for individual talkers. Phoneme substitution err...

ULFA MIRANDA DAMANIK. The Thickness of The Skin on White Rat (Rattus norvegicus) as an Animal Model of Menopause After Given Sea Cucumber (Holothuria scabra) Flour. Supervised by CHAIRUN NISA ' and SUPRATIKNO. Sea cucumbers are marine resources that are abundantly found in Indonesia. Sea cucumbers are known to contain steroid hormones, essential amino acids, collagen and vitamin A, so that the sea cucumbers are believed to be a food that contains nutrients that are good for consumption and is believed to have pharmacological effects. Therefore, this study aimed to determine the effect of sea cucumbers flour to the thickness of the skin of white rats (Rattus norvegicus) animal model of menopause. This research used 30 female rats and were divided into 6 groups (all groups were given corn oil 2ml): N (non ovariectomy), KN (ovariectomy), KP (ovariectomy and were given estradiol 30 μg/100 g BW) and group ovariectomy who were given flour sea cucumber D1 (30 μg/100g BW), D2 (40 μg/100g BW) and D3 (50 μg/100g BW). After 45 days postovariektomy, the rats were given treatment for 20 days (force feed). At the end of treatment, the skin were evaluated for histological method using hematoxylin eosin (HE) staining. The thickness of the skin were measured using a micrometer then analyzed with ANOVA test and T test by SPSS (Statistical Product and Service Solutions). The results of this research show the groups D1 and D2 have different thicknesses evident only in the epidermis compared with KN group. The thickness of the epidermis in D1 and D2 is equal to 24.1 ± 2.0 μm and 25.9 ± 2.8 μm. While in the D3 group are significantly different thicknesses both in the epidermis and dermis is equal to 26.8 ± 2.9 μm and 1,240 ± 54 μm. The conclusion of this study is sea cucumbers flour can increase the thickness of the skin of rat animal model of menopause.


In the present study, the microstructure features and the number of growth increments in the statoliths, beaks, and eye lenses of the mitre squid, Uroteuthis chinensis (Gray, 1849), were examined. Growth increments in three regions of the statolith [the dorsal dome (SDD), lateral dome (SLD), and rostrum] were observed; those of the SLD had the most stable increment widths. The SLD and SDD had a similar number of growth increments. Increment number in the rostrum sagittal section (RSS) of the upper beak was lower (about 30 increments) and that of the eye lens was many times higher (about 3–5 times) than those in the statolith and the beak. The best fits against mantle length were the number of growth increments of the beak, SLD, and eye lens. The relationship between mantle length and growth increments of SLD could be described with two separate equations, possibly indicating that two different cohorts were sampled. Based on the growth increments of SLD, the maximum age of U. chinensis in our study was inferred to be 169 d.


Problem There is evidence that university students have poor eating behaviors that can lead to short and long term negative health effects. Understanding the influences on eating behaviors will aid universities and health agencies in developing effective healthy eating promotion strategies. Purpose and Method To determine the impact of a range of influencers on healthy eating behaviors, a tested and ethics approved questionnaire was distributed to a random sample of students at two universities. Responses (n=188) were statistically analyzed and logistic regression was conducted. Results Mean daily food group servings were below recommendations for the vegetables/ffuits and grain products groups. The regression models for minimum vegetable/fruit group were statistically significant for healthy eating, media/social and the professional advice influencer scales. For the meal/altemates, the models were significant for budget constraints, professional advice and nutrition self-efficacy influencer scales. No significant relationships were found for the other two food groups. Conclusions There is a need to improve the eating behaviors of university students and different influences affect consumption of different food groups. A focus on particular influences can enable a targeting of healthy eating promotion and communication strategies on deficient food groups. Introduction University students are at a critical phase in their lives and making decisions about their health and, in particular, eating behaviors. However, there is evidence that these decisions need improvement. It has been reported that the diets of young adults, females in particular, lacked vegetables, fruits and milk, but were high in fat and sugars (Garriguet, 2007; Statistics Canada, 2013; Centre of Disease Control and Prevention [CDC], 2015). This has likely contributed to over 50% of Canadians reported to be overweight and over 20%, obese (Statistics Canada, 2014a), and similarly, an obesity rate of 35% for adults in the USA (CDC, 2015). Health risks associated with poor eating behaviors, overweight, and obesity, include diabetes, heart disease and cancer (Von Ah, Ebert, Ngamvitroj, Park & Duck-Hee, 2004; Boyle & LaRose, 2009; Gibney, Lanham-New, Cassidy & Vorster, 2009; World Cancer Research Fund, 2007) as well as short-term effects such as fatigue, stress, decreased ability to concentrate and poor body image (Hol-Denoma, Joiner, Vohs & Heatherton, 2008; Kandiah, Yake, Jones & Meyer, 2006; Gores, 2008). Therefore, in order to maximize the academic and social development potential for university students, healthy eating behaviors need to be established and/or reinforced. Understanding the complex relationships among individual and environmental influences, as described by the determinants of healthy eating (Raine, 2005; LaCaille, Sauner, K ram beer & Pedersen, 2011), can assist universities and health agencies to develop effective health promotion and support strategies. The purpose of this study was to determine the impact of selected influences on the self-reported food frequency intakes of a random sample of univesity students. The influences included perceptions about personal health and lifestyle (Boyle & LaRose, 2009; Kandiah et al, 2006; Vaex, Kristenson, & LaFlamme, 2004; Sun, 2008; Jackson, Berry & Kennedy, 2009; Paquette, 2005), healthy eating behavior (Taylor, Evers & McKenna, 2005; House, Su & Levy-Milne, 2006; Kolodinsky, Harvey-Berino, Berline, Johnson & Reynolds, 2007; Ha & Caine-Bish, 2009), the impact of budget constraints (Vaez, et al, 2004; House et al, 2006; Garcia, Sykes, Matthews, Martin & Leipert, 2010; Brown, Dresen & Eggett, 2005; Deshpande, M.D. Basil & D.Z. Basil, 2009), nutrition self-efficacy (Von Ah, 2005; Boyle & LaRose, 2009; Deshpande et al, 2009; Kim, Ahn & No, 2012; Lockwood & Wohl, 2012; Yilmaz, 2014) and various information sources, including family, friends, professionals, media and websites (House et al, 2006; Lockwood & Wohl, 2012; Ostry, Young & Hughes, 2008; Freisling, Haas & Elmadfa, 2009; Lee, 2010). …


Theodor Kocher (1841–1917) was Switzerland's greatest surgeon. Indeed, his name ranks high in the surgical world's hall of fame. In the latest of his ongoing series of articles, Harold Ellis explores Kocher's contribution to the field.


Key Points A homogeneous population of LMSCs is purified from mouse lungs using Sca-1. LMSCs modulate neutrophil and macrophage functions and show bacterial killing. LMSCs improve survival, minimize inflammation, and enhance bacterial clearance. Klebsiella pneumoniae is a common cause of Gram-negative pneumonia. The spread of antibiotic-resistant and hypervirulent strains has made treatment more challenging. This study sought to determine the immunomodulatory, antibacterial, and therapeutic potential of purified murine stem cell Ag-1+ (Sca-1+) lung mesenchymal stem cells (LMSCs) using in vitro cell culture and an in vivo mouse model of pneumonia caused by K. pneumoniae. Sca-1+ LMSCs are plastic adherent, possess colony-forming capacity, express mesenchymal stem cell markers, differentiate into osteogenic and adipogenic lineages in vitro, and exhibit a high proliferative capacity. Further, these Sca-1+ LMSCs are morphologically similar to fibroblasts but differ ultrastructurally. Moreover, Sca-1+ LMSCs have the capacity to inhibit LPS-induced secretion of inflammatory cytokines by bone marrow–derived macrophages and neutrophils in vitro. Sca-1+ LMSCs inhibit the growth of K. pneumoniae more potently than do neutrophils. Sca-1+ LMSCs also possess the intrinsic ability to phagocytize and kill K. pneumoniae intracellularly. Whereas the induction of autophagy promotes bacterial replication, inhibition of autophagy enhances the intracellular clearance of K. pneumoniae in Sca-1+ LMSCs during the early time of infection. Adoptive transfer of Sca-1+ LMSCs in K. pneumoniae–infected mice improved survival, reduced inflammatory cells in bronchoalveolar lavage fluid, reduced inflammatory cytokine levels and pathological lesions in the lung, and enhanced bacterial clearance in the lung and in extrapulmonary organs. To our knowledge, these results together illustrate for the first time the protective role of LMSCs in bacterial pneumonia.


Neuroblastoma is a childhood malignancy derived from the primordial neural crest cells that form the sympathetic nervous system. These tumours are notorious for their early tendency of metastasis. Symptoms arising from these such as proptosis can be the only manifestation of metastatic neuroblastoma (1). Early investigation is important, as metastatic disease requires aggressive management. We present a case of a 6 year old girl initially presenting with proptosis. INTRODUCTION: Virchow originally described Neuroblastoma in 1863. By the beginning of the 20 th century, its origin in sympathetic tissue was determined by Zuckerkandl and Kohn. It is the third most common pediatric malignancy, after leukaemia and central nervous system tumours (2). The median age at diagnosis is 22 months, and more than 95% cases are diagnosed by the age of 10 years. Approximately 1% of the patients present initially evidence of metastatic disease without a readily identifiable primary lesion. Neuroblastoma commonly metathesizes to bone (60%), regional lymph nodes (45%), orbits (20%), liver (15%), intracranial (14%) and lung (10%)(2). CASE REPORT: A 6 year old girl presented with the complaint of progressively increasing proptosis of bilateral eyes. The girl underwent contrast enhanced CT Scan of brain and orbits which revealed: 1. Bilateral enhancing retro-orbital masses. 2. Enhancing soft tissue masses overlying the bilateral parietal bones. 3. Separation of the coronal sutures. 4. Enhancing extra axial intracranial soft tissue mass suggestive of dural metastasis.


The concept of human rights in Islam will not be separated from the concept of nature and haqq inherent in humans, if the disposition is a condition innate nature of inherent human dignity inherent in the term haqq Quran is in Arabic has some sense that is true or truth. so if the haqq concept is defined as al-Haqq it will lead to the Lord God Almighty as the absolute truth. Then the next haqq meaning in English can be interpreted in terms of rights,in French is defined as droit, and in Indonesian translated as hak. In the concept of rights as a human right that in Arabic, haqq is not a single concept but it coupled with another termination of alwjaib which means duty or obligation. So that, the concept of haqq that coupled with al-wajib is an understanding about haqq that lead to human rights. Human rights in Islam can be said as moral obligations that owned by everyone as God's creature. Alquran in Islam distinguish the understanding of human rights into rights for each human being and rights for certai people such as weak, poor, traveler, women, and non-muslim. Human rights position is placed between religious world (ecclesia) and secular world (saeculum), it's because human rights as natural right comes from God but in efforts it needs recognition, protection, and realization from secular world, in this case divinity elements changed with a human dignity concept by the secular adherents. This can be seen in western concepts about human rights that excluded dignity concepts from their understanding whether it as divine or sovereign, so that human rights is all about moral concept without dignity values on it. Concerning the connection between morality and religion, can be explained that morality does not need religion but as vice verse, religion needs morality. The combinations between religion and ethic codes in social live will face the other systems such as economic, politic, law,education, etc. in this fields the religion concepts will infiltrate and affect each field to form moral codes that worth to be followed. in this matter can be concluded that morality forms connector bridges between religious system and another systems that affecting each other and inseparable.


The 5th generation of the cellular mobile communication system (5G) is in the meantime stepwise being deployed in mobile carriers' infrastructure. Various standardization tracks as well as research activity are investigating the exploitation of the very flexible 5G system architecture for customized deployments, meeting requirements of the vertical industry, such as for automotive, factory, or smart city. A very common base is a cloud-native development and decentralized deployment of the 5G system along with services in distributed resources per the Multi-Access Edge Computing (MEC) architecture to locate services topologically close to (mobile) users, e.g. along public roads, and to enable low-latency communication with local services. Automated management of such a distributed deployment in an agile environment is a prerequisite. This paper investigates the use of Recurrent Neural Networks (RNN) for accurate user mobility prediction in an automotive scenario. By the use of simulated vehicular traffic, a suitable RNN configuration using Long Short-Term Memory (LSTM) has been found, which provides accurate prediction results. Proof of value has been accomplished by an experimental decision algorithm, which balances the use of available distributed resources through service scale, migration or replication decisions while meeting mobile users' expectation on the experienced service quality.


face smooth, with tool marks all over it, but not in a pattern. It was found lying on the surface of Hazeldown, Stockbridge, Hants, and is kindly lent for publication by Miss Winifred Beddington. There are several plates of copper celts from Ireland in journal of the Anthropological Institute, xxxi (1901), 265, and the type may have been in local use for centuries; but it is approximately dated by the crescents in England, and the latter type is known to have been widely distributed in north-west Europe. Overseas trade was evidently in full swing at the dawn of the Bronze Age, and Ireland was an active participant. In 1912 our Fellow Mr. Crawford mapped the distribution of flat celts in the British Isles, adding an inventory of the implements and stone moulds for making them, as well as the sources of tin and copper (Geographical Journal, xl, pp. 186, 197, 307); and Mr. Armstrong's map of flat celts in Ireland was published three years later in our Proceedings, xxvii, 255.


A selected antibody enzyme immunoassay (SAEIA) for detection of Xanthomonas campestris pv. citri (cause of citrus bacterial canker) was developed, in which a rabbit antiserum specific for X. c. citri strain QN8201, immobilized cell fragments of X. c. citri strain QN7501, and β-D-galactosidase-labeled goat anti-rabbit immunoglobulin G were used. The SAEIA was specific for strains of X. c. citri and showed very little cross-reaction with single strains of X. c. pv. pruni and X. c. pv. oryzae, or with several strains of other microorganisms (.)

ABSTRACT The prevalence and consequences of self-reported sexual abuse among 164 male and 22 female practitioners of sadomasochistic sex was explored. A questionnaire exploring psychological health, social adjustment, and sexual behavior was distributed among members of two sadomasochistically oriented clubs. The results showed that the prevalence of self-reported sexual abuse was higher among the participants as compared to the general Finnish population norms. Also, the participants that reported abuse were more likely to have attempted suicide, to have sought psychological support, and to have visited a physician due to physical injuries. Self-reported sexual abuse was also associated with poorer social adjustment, and higher sexual neuroticism. Further, the higher the frequency of abuse, the poorer the body image of the abused male participants. In conclusion, even though the majority of the participants did not report childhood sexual abuse, it had adverse consequences and altered some aspects of the sexual behavior of the individuals that had been abused.


The article contains information about the records of 43 species of alien vascular plants made in the Yamalo-Nenets Autonomous District. Field surveys were carried out in 2012-2016. The detected invasive species were growing on wasteland, abandoned and new lawns, in ditches and on roadsides. A majority of the reported species (Avena fatua, A. sativa, Barbarea vulgaris., Brassica rapa, Bunias orientalis, Cannabis sativa, Cirsium arvense, Crepis tectorum, Cyanus segetum, Dactylis glomerata, Erodium cicutarium, Fallopia convolvulus, Geum aleppicum, Glechoma hederacea, Helianthus lenticularis, Lappula squarrosa, Lathyrus pratensis, Lepidium ruderale, Lycopersicon esculentum, Medicago falcata, Plantago media, Potentilla norvegica, Raphanus raphanistrum, Rubus idaeus, Rumex pseudonatronatus, Scorzoneroides autumnalis, Secale cereale, Silene tatarica, Solanum tuberosum, Sonchus arvensis, Trifolium hybridum, T. medium, Triticum aestivum, Tussilago farfara, Typha latifolia, Urtica dioica) have been previously known from a few locations in the district. Onobrychis viciifolia Scop. and Echium vulgare L. are new for the regional flora. There is little information in the literature and in herbaria about Hordeum jubatum, Lepidotheca suaveolens, Senecio vulgaris, Melilotus albus and M. officinalis in the Yamalo-Nenets Autonomous District. However, these species are getting successfully naturalized, turning into common synanthropic plants in settlements of the district. Data from the herbarium label, information on the distribution in the Yamalo-Nenets Autonomous District and, if necessary, brief comments on the distribution in Siberia with specification for Western Siberia are provided for each species.


Objective:To evaluate the effects of the surface roughness of dental base restoration materials on the adherence of Streptococcus mutans.Method:Forty standard specimens(8 mm×8 mm×1 mm) made in cobalt-chromium alloy were divided into 5 groups.5 different polishing procedures were used on these specimens.The surface roughness of the specimens were determined using TR200 hand-held roughness instrument.The adherence of S.mutans on the surface of specimens were observed.Result:Correlation analysis between the adhesive capacity of S.mutans and the surface roughness of the specimen suggested a good positive correction(P 0.01).The values of S.mutans adhering on the surface of different specimens showed a significant difference(P 0.01).Conclusion: The surface roughness of dental base is of clinical importance in the process of bacterial retention.The restoration needs proper treatment modality in order to obtain and maintain a surface as smooth as possible.


The aim of this study is to propose a practical, theory-based framework that can be applied in analyzing the modeling of quality physical education based on kinesthetic perception as a socio-technical entity, and in identifying potential improvements. Physical education learning in elementary schools is one of the important stages for optimizing the development of a child's fundamental movement, stimulating motor abilities and physical activities that stimulate intelligence optimization. However, kinesthetic perception is the feeling of muscle that directs the movement correctly, without using the eyes. Method of this research used Modeling Process and Mingers' sequential type multi-method research design. Since there is no single model, this study consolidated a hybrid model (motor learning Model, sport education model, Tactical Games Approach model and VARK learning model). Research process (Constructing thematic questionnaires, web-based data collecting and analyzing data) and this article presents the results of the first stage i.e. theory adaptation as resilient arguments about the need to develop a quality physical education learning model based on kinesthetic perceptions for elementary school students.


Photovoltaics is increasingly used to convert solar energy into electricity in households, including in Poland. The development of this type of renewable energy results, on the one hand, from legal regulations related to climate and energy policies, and on the other hand, from the numerous benefits connected with the use of photovoltaics. These include both economic and environmental advantages. The aim of the work was to assess the profitability of installing photovoltaics in a Polish household in 2019–2021. Therefore, the costs of the investment are presented, as well as the benefits, mainly in economic terms. Different calculations and estimates concerning return on the invested capital are also shown. During the 31 months covered by the study, the cumulative positive balance of electricity that was generated above the energy consumed in the household exceeded 2,900 kWh, which resulted in an economic surplus of over PLN 1,600 (about EUR 360). What is more, the investment contributed to the protection of the natural environment which is the added value of the photovoltaics.


Recent field research has shown that ambient concentrations of ozone(O{sub 3}) have the potential to reduce yield of a number of economically important crop species. Less emphasis has been placed on characterization of the effects of O{sub 3} on growth of the total plant that ultimately determines yield. In this study, the authors measured season-long growth of field-grown cotton that was exposed to a range of O{sub 3} concentrations at two levels of soil moisture, well-watered (WW) and water-stressed (WS). The cotton was exposed for 12 h/d throughout the growing season in open-top chambers to five O{sub 3} concentrations. Three cotton plants were sampled from each chamber at 2-to 3-wk intervals during the season, and biomass and growth measurements were made on all major plant parts. Ozone stress reduced leaf and root biomass in particular, while stem tissues were less affected. Water stress caused fewer significant effects overall than did O{sub 3}, although it appeared to reduce the growth of most plant parts, especially at low O{sub 3} concentrations.


It's well known that collecting traffic information by cell phone CEL-ID location technique-firstly get subscribers 'travel routine by analyzing and retrieving CELL-ID number uploaded by cell phone customers, then other necessary information (e.g. Origin-Destination Flow, the number of Residents and Jobs) gained after further technical processing. However, since all of these indicators are based on traffic analysis zone (TAZ) unit and restricted by the accuracy of CELL-ID location method and communication theory, the size of the traffic analysis zone has significant impact on the accuracy of indictors. For example, the relative error of the indicator will increase if the traffic analysis zone is divided too small. But if traffic analysis zone is divided too big, the trip distribution characteristic won't be presented clear. That's why this dissertation is to contribute a reasonable methodology of solving traffic analysis zone size based on CELL-ID location technique.


I would like to offer my gratitude to the team of Journal of Indo Pacific Academy of Forensic Odontology for providing me with the opportunity to share my views based on my experience as a Disaster Victim Identification (DVI) team member in Nepal. Natural disasters are a major national concern. India ranks among the top ten countries in the world in terms of disaster fatalities. The National Disaster Management Authority (NDMA) is India's principal disaster management authority. The Disaster Management Act of 2005 was established on September 27, 2006. The NDMA establishes rules for disaster management in India. To deal with disasters in India, NDMA is in charge of creating policies, laying down guidelines and best practices, and coordinating with the State Disaster Management Authorities (SDMAs).


The policies regarding resident physician work hours are constantly being evaluated and changed. However, the results of randomised control trials (RCTs) are mixed. This systematic review of RCTs aims to synthesise the evidence associated with resident duty hour restrictions and its impact on resident‐ and patient‐based outcomes.


The reversible condensation of potassium into large K + O coadsorption islands that occurs during the O2 + H2 reaction on a Rh(110) surface predosed with potassium has been studied in the 10-7 mbar range at temperatures between 533 and 623 K and with K coverages between 0.025 and 0.11 ML. Scanning photoelectron microscopy has been used as a spatially resolving in situ method to follow the development of the condensation process via calibrated K and O profiles. A Pt patch evaporated onto the Rh(110) surface served as a nucleation center for the reaction fronts. The coadsorbate phases evolving in the course of the condensation were characterized by local photoelectron spectra. Only at high enough temperature (∼580 K) is a nearly complete redistribution of the potassium by reaction fronts observed, whereas at low temperature, a substantial amount of the K + O coadsorbate remains on the reduced surface. The formation of a high-coverage (8 × 2) K + O phase characterized by an energy-shifted component in the Rh...


Iodine-sulfur(IS) hydrogenation production process consists of three sections, which are so called a Bunsen reaction section, a HI decomposition section and a decomposition section as a closed cycle. For highly efficient operation of a Bunsen reaction section, we investigated the phase separation characteristics of system into two liquid phases(-rich phase and -rich phase) in the high temperature ranges, mainly from 353 to 393 K, and in the molar ratio of . The desired results for the minimization of impurities in each phase were obtained in conditions with the higher temperature and the higher molar composition. On the basis of the distribution of to each phase, it is appeared that the affinity between and was more superior to that between and .


One of the main challenges which is addressed to the Romanian economy is that if the integration in the European Union represents a moment of discontinuity. It is to mention that the custom duties were abolition between Romania and the European Union (January 1st, 2004) made the Romanian companies to be in a direct competition, at least at the product markets level, with the companies in the European area. From this point of view, it can be appreciated that the Romanian integration effect will be quite low and the "danger" of integration is many times over dimensioned.


Janice Wearmouth, lecturer in the School of Education at the Open University, interviewed a group of adult male prisoners in 1995 about their school experiences, as part of a wider study concerned with spoiled identity. One of them, Jack, had been classified as 'maladjusted' during the 1970s, and the interview with him provides powerful evidence of important definitional differences between his own perceptions of his abilities and the impressions of those who labelled him.


To integrate the concept of high-quality development into urban land use, this paper explores the spatial-temporal pattern characteristics of urban land intensive use (ULIU) in the Yangtze River Delta with a constructed evaluation index system, the comprehensive evaluation model and exploratory spatial data analysis based on the spatial panel data of 41 cities from 2010 to 2020. The paper also analyzes the spatial effects and influencing factors of ULIU with the spatial Durbin model and partial differential method. The results demonstrate that: 1) The ULIU in the Yangtze River Delta generally showed consistent growth from 2010 to 2020. However, there was significant spatial differentiation among different regions, as the land intensive use level was higher in cities along the Yangtze River and coastal cities around Hangzhou Bay, while relatively lower in the mountainous and hilly cities in Zhejiang and southwestern Anhui. 2) The ULIU level showed significant positive global spatial autocorrelations, while its local spatial characteristics mainly included four types dominated by high-high agglomeration and low-low agglomeration from 2010 to 2020. 3) Economic development, industrial structure and infrastructure could remarkably promote the ULIU of both local and neighboring cities. Scientific and technological innovation could significantly enhance the ULIU of local cities; population urbanization and government financial pressure showed significant negative effects on the ULIU of local cities; while all the above three factors had insignificant effects on the ULIU of neighboring cities. These findings are of great significance for revealing the internal mechanism underlying the spatial effect of land intensive use and provide some guidance for improving the level of ULIU in the Yangtze River Delta from the perspective of regional cooperation.


Inner Mongolia's economic developed rapidly on which the new urbanization based. proportion of non farming population increased year by year,the employment structure optimize gently,the quality of the population increase. Urban residents' life quality improved significantly,the social service function gradually improved. The quality of urban environment improve,health status was improved. However,the rapid urbanization can not develop in coordination with industrialization and economy; the process of urbanization and industrial structure and employment structure is asymmetry;the capacity to absorb employment labor for the Second and three industry is short; the gap between urban and rural areas is obvious,the present trend expands. Improving the quality of economic development and the capacity to absorb employment labor for the Second and three industry; enhancing the heterogeneity of the city,accelerating the construction of city circle to form the new town cluster; actively support the growth of the county,focusing on the construction of key towns; Implementing the household registration system and land reform are important policy options for new urbanization.

Primary Care Groups and Primary Care Trusts have the task of achieving an integrated health care service, serving local communities. A regional Education and Training Consortium commissioned a 1-year study to provide information in order to develop a workforce strategy that aimed to achieve this agenda. The study involved individuals who plan, provide and/or manage primary and community health care service in three Health Authorities, working in partnership. The three phases of data collection included focus groups, individual interviews and a survey, which produced qualitative and quantitative data. The findings outlined in this paper primarily focus on practice nurses and integrated care. Several tensions emerged in this context which could inhibit the development of integrated care. These included conflict within professional relationships, inequality in pay and working conditions, a lack of understanding of how integrated care would or could translate into practice and turbulent environmental contexts. We argue, these tensions often created gaps between policy, practice and professional discourses which, unless acknowledged and understood may result in integrated care remain a health, but unachievable, rhetoric.


The magnetic susceptibility of tris(2,2′-dipyridyl)manganese complexes, [Mn(dipy)3] · 2THF and Li[Mn(dipy)3] · 4THF (THF: tetrahydrofuran), has been determined over a temperature range of 1.5–300 K. The susceptibility of Li[Mn(dipy)3] · 4THF can be explained with a radical ion model, in which three 2,2′-dipyridyl radical ions are coordinated to a manganese(II) ion, suggesting the formula [Mn2+(dipy−)3]− rather than [Mn−(dipy0)3]−. A similar model is applicable to [Mn(dipy)3] · 2THF as well.


ABSTRACT
 The objectives of the research were (1) to give descriptive account of the factors causing the student's disruptive behaviors in learning English; (2) to overcome the student's disruptive behaviors in learning English through interpersonal communication.
This research applied descriptive qualitative research. By using purposive sampling technique, one student of SMP Negeri 18 Makassar was chosen as the research subject which is categorized as the most disruptive student in learning English. The data were obtained through interview, observation and personal interaction and analyzed based on procedure of data analysis that consisted of the data collection, the data reduction, the data display, and conclusion: drawing/ verification.
The findings showed that (1) the factors causing the student's disruptive behaviors in learning English were (a) seeking attention, (b) classmate, (c) close friend, (d) learning environment, (e) family, and (f) social environment and (2) to overcome and decrease the student's disruptive behaviors, the researcher used interpersonal communication through caring, persuading, advicing, warning, prohibiting, and appreciating which delivered verbally and/or non-verbally or both. It can be inferred that the most dominant cause of student's disruptive behaviors was the external factors and Interpersonal communication was powerful to decrease the student's disruptive behaviors.


The book 'Identity in Organizations: Building Theory Through Conversations,' edited by David A. Whetten and Paul C. Godfrey, is a useful and interesting foray into one community's conversation about identity and identifications and organizations. The book is organized into three different parts, each engaging ideas of identity from a different perspective. In Part I the authors look at what organizational identity means, trying to approach it from a more traditional macro-organizational theory perspective. Part II authors discuss identity in light of the question of what identity implies for strategy. Finally, in Part III of the book, the authors wrestle with the question of how people identify with organizations.


Siegel's analysis on membrane transport in the Laplace domain [J. Phys. Chem. 95 (1991) 2556] in terms of transmission matrix, T(s), has been extended to a more useful formulation. This is achieved by combining uses of the matrix transport equations appropriate for void initial condition, or for saturated equilibrium, or of Dirac delta functional type and the theorem det[T(s)] = 1. This formulation enables us to expand T(s) in power series of the Laplace variable, s, with the expansion coefficients as the algebraic functions of the experimentally measurable transport parameters. Utility of the formulation is illustrated in the estimation of the experimentally inaccessible time moments for the first passage or residence times. It was also applied to the percutaneous drug delivery to obtain from the experimental data. The higher moments of the time lag or time lead using a graphic method.


The relationship among asphalt, mortar and mixture performance was analyzed by grey correlation method by means of asphalt rheological test and hot mix freeze-thaw split test in this paper. The results show that the rheological properties of asphalt as well as asphalt mortar are closely related to HMA performance. Rheological index has a good advantage in explaining HMA pavement diseases. Asphalt stiffness, cohesion, yield stress, rutting coefficient, multiple stress creep and recovery have a high correlation with the strength of the mixture; meanwhile, softening point, normal stress, interface bonding ability of asphalt mortar and volume index of mixture have a high correlation with the water stability of the mixture. In the evaluation of asphalt and asphalt mortar, methods such as stress creep recovery, stress scanning (yield stress, normal stress) and interface bond test should be further proposed and popularized.


The purpose of this study was to analyze and evaluate self-reported bullying experiences, responses to those bullying experiences, student reported school safety and school climate at Menomonie Middle School in February, 2005. The sample was comprised of 2 12 sixth graders, 224 seventh graders, and 2 17 eighth graders, approximately 89.5% of the total student population. There were 305 males, 343 females, and 5 students that chose not to identify themselves. Students were asked to complete a survey describing bullying experiences and overall school climate concerns regarding bullying. The survey was administered and collected by Menomonie Middle School prior to the beginning of the research. Data was collected and descriptive and correlation statistics were used to test the research hypotheses and answer research questions. One general finding of this study is that there seems not to be a statistical correlation between grade level and number of self-reported bullying experiences at Menomonie Middle School. There also is a possible trend, but not a statistical significance, between gender and number of self-reported bullying instances with females reporting more instances. Additional themes are presented and discussed as they pertain to student experiences with bullying and school climate.


Since the formal dismantling of apartheid in the early 1990s, the South African government has placed much emphasis on redressing the social imbalances caused by apartheid, including overcoming patterns of segregation inherent in the apartheid city. The National Development Plan, in specifying its principles for the spatial development of South African settlements, outlines the principle of spatial justice: that apartheid's policy of confining particular groups to limited spaces must be reversed. In order to inform the future success of the National Development Plan's goal of social cohesion, research into residential segregation can provide one indication of how socially integrated South African society is. The purpose of this article is to measure racial residential segregation at different geographic scales for the South African cities of Cape Town and Johannesburg, and to measure how residential segregation has changed over time using data from the population censuses of 1991, 1996, 2001 and 2011. Theil's entropy index of segregation, applied to grid squares of varying spatial sizes, is used to calculate both racial diversity and racial segregation for both cities. The results show that from 1991 to 2011, segregation levels decreased at all geographic scales in both cities. However, despite this decrease, both cities remain highly segregated. If the census enumeration area or small area is used as the base from which to calculate segregation, Cape Town as a whole is more racially segregated than Johannesburg. However, Johannesburg is more racially segregated than Cape Town at larger geographic scales.


Abstract The complementary activity of 4-hydroxphenylpyruvate dioxygenase (HPPD) inhibitors and atrazine is well documented, but the use of atrazine is restricted in some geographic areas, including the province of Quebec in Canada, necessitating the evaluation of atrazine alternatives and their interactions with HPPD inhibitors. The objectives of this study were to determine whether mixing HPPD inhibitors with atrazine alternative photosystem II (PS II) inhibitors, such as metribuzin and linuron applied PRE or bromoxynil and bentazon applied POST, results in similar control of multiple herbicide–resistant (MHR) waterhemp [Amaranthus tuberculatus (Moq.) Sauer] in corn (Zea mays L.). Ten field trials, five with herbicides applied PRE and five with herbicides applied POST, were conducted in Ontario, Canada, in fields infested with MHR A. tuberculatus. Isoxaflutole, applied PRE, controlled MHR A. tuberculatus 58% to 76%; control increased 17% to 34% with the addition of atrazine, metribuzin, or linuron at three of five sites across 2, 4, 8, and 12 wk after application (WAA). The interaction between isoxaflutole and PS II inhibitors, applied PRE, was additive for MHR A. tuberculatus control and biomass and density reduction. Mesotrione, tolpyralate, and topramezone, applied POST, controlled MHR A. tuberculatus 54% to 59%, 61%, and 44% to 45%, respectively, at two of five sites across 4, 8, and 12 WAA. The addition of atrazine, bromoxynil, or bentazon to mesotrione improved MHR A. tuberculatus control 29%, 34%, and 22%; to tolpyralate, improved control 2%, 20%, and 10%; and to topramezone, improved control 3%, 14%, and 8%, respectively. Interactions between HPPD and PS II inhibitors were mostly additive; however, synergistic responses were observed with mesotrione + bromoxynil or bentazon, and tolpyralate + bromoxynil. Mixing atrazine alternatives metribuzin or linuron with isoxaflutole, applied PRE, and bromoxynil or bentazon with mesotrione or tolpyralate, applied POST, resulted in similar or better control of MHR A. tuberculatus in corn.

SUMMARY The purpose of this thesis is to study algorithmic questions that arise in the context of game theory and microeconomics. In particular, we investigate the computational complexity of various economic solution concepts by using and advancing methodologies from the fields of combinatorial optimization and approximation algorithms. We first study the problem of allocating a set of indivisible goods to a set of agents, who express preferences over combinations of items through their utility functions. Several objectives have been considered in the economic literature in different contexts. In fair division theory, a desirable outcome is to minimize the envy or the envy-ratio between any pair of players. We use tools from the theory of linear and integer programming as well as combinatorics to derive new approximation algorithms and hardness results for various types of utility functions. A different objective that has been considered in the context of auctions, is to find an allocation that maximizes the social welfare, i.e., the total utility derived by the agents. We construct PCP-based reductions from multi-prover proof systems to obtain hardness results, given standard assumptions for the utility functions of the agents. We then consider equilibrium concepts in games. We derive the first subexponential algorithm for computing approximate Nash equilibria in 2-player noncooperative games. We extend our result to multi-player games and we further propose a second algorithm based on solving polynomial equations over the reals. Both algorithms improve the previously known upper bounds on the complexity of the problem. Finally, we study game theoretic models that have been proposed recently to address incentive issues in Internet routing. We obtain a polynomial time algorithm for computing equilibria in such games, i.e., routing schemes and payoff allocations from which no subset of agents has an incentive to deviate. Our algorithm is based on linear programming duality theory. We also obtain generalizations when the agents have nonlinear utility functions.


Metallic delafossites ( ABO2) are layered oxides with quasi-two-dimensional conduction layers. Metallic delafossites are among the most conducting materials with the in-plane conductivity comparable with that of elemental metals. In this Perspective, we will discuss basic properties and future research prospects of metallic delafossites, mainly focusing on thin films and heterostructures. We exemplify the fascinating properties of these compounds, such as high conductivity and surface polarity, and discuss how it can be utilized in thin films and heterostructures.


The use of numerical simulations in geotechnical engineering today is often limited to the investigation of the serviceability limit state (SLS). Therefore, the main focus up to now was more on the deformation prognosis for geotechnical constructions than the geotechnical design itself. Nevertheless, numerical methods like the Finite-Element-Method (FEM) for example can be a valuable tool to investigate the bearing capacity of geotechnical structures as well. E.g. existing structures which cannot be calculated using classical analytical approaches can be investigated with numerical simulations to estimate the remaining bearing capacity. In the present paper, the use of numerical methods for the design of geotechnical structures will be discussed. First, the approved ϕ - c reduction method is recalculated and verified with the help of a script based on the Python programming language. Afterwards, the Python script is extended so that the diameter of an Embedded Beam Row element can be successively reduced automatically similar to the ϕ - c reduction. Finally, a short outlook is given in which direction the research project should proceed.


We study the speed of convergence of n R fdμ in the local limit theorem on R under very general conditions upon the function f and the distribution μ. We show that this speed is at least of order 1 n and we give a simple characterization (in diophantine terms) of those measures for which this speed (and the full local Edgeworth expansion) holds for smooth enough f . We then derive a uniform local limit theorem for moderate deviations under a mild moment assumption. This in turn yields other limit theorems when f is no longer assumed integrable but only bounded and Lipschitz or Hölder. We finally give an application to equidistribution of random walks.
