A series of WO3 supported on ordered mesoporous zirconium oxophosphate (X wt% WO3/M-ZrPO) solid acid catalysts with a WO3 loading from 5 to 30 wt% were successfully synthesized, and their structure properties were characterized by X-ray diffraction (XRD), Raman spectroscopy, N2-physisorption, transmission electron microscopy (TEM), UV-visible diffuse reflectance spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, H2 temperature-programmed reduction (H2-TPR) and X-ray photoelectron spectroscopy (XPS). The catalytic performance of X wt% WO3/M-ZrPO in liquid phase benzylation of anisole was studied and the relation between activity and states of tungsten species was investigated detailedly. The maximum catalytic activity was reached at a 20 wt% WO3 loading, which possessed highly dispersed WO3 species and the strongest Bronsted acidity. Meanwhile, the well dispersed WO3 species strongly interacted with M-ZrPO, therefore, both sintering and leaching of WO3 species were effectively restrained. Moreover, compared with the traditional zirconium phosphate synthesized from the sol–gel method (ZrPsol–gel), the M-ZrPO with an abundant ordered mesostructure was propitious for improving the dispersion of WO3 species and catalytic performance. In addition, the 20 wt% WO3/M-ZrPO showed a markedly higher catalytic activity than H-ZSM5, H-Beta and 20 wt% WO3/ZrPsol–gel. Furthermore, the catalyst showed no discernible loss in activity or selectivity after five cycles.


In today's world, the development and research of optoelectronic materials and devices based on solid‐state luminescence is essential. Due to their versatile application possibilities, e.g. as light‐emitting diodes or lasers, they are already indispensable. This work presents three halogenated anthracene derivatives [9‐PPh2‐10‐X‐(C14H8)] and their respective photoluminescent behavior in solution and in the solid state. The formation of halogen–π interactions in the solid state leads to unanticipated luminescence properties for the chlorinated species, resulting in a strong bathochromic shift, green fluorescence and a longer lifetime. In contrast, the other two derivatives, which in turn form only weak π–π interactions due to a small overlap of the anthracene rings, barely change their luminescence behavior in the solid state. By employing additional charge density studies, the structure–property correlation is also investigated. In particular, focus is given to halogen bonding and halogen–π interactions and their influence on photophysical properties of the studied compounds. Through the new knowledge gained, this study will help in the future development and selective application of the photophysical properties of solid‐state luminescent materials.


Flue-cured tobacco floating-seedling in little canopies was greatly affected by changing weather. Flue-cured tobacco seedling was affected by low temperatures in early spring and high temperatures in late spring in Qianxi ′nan. Qianxi′nan was rich in cavern resources,making use of cavern′ s temperature constancy for floating-seedling could avoid natural calamities. This research chose the ordinary variety of flue-cured tobacco Yunyan85 for contrast test between ordinary floating-seedling and cavern floating-seedling. The results indicated that cavern floating-seedling could improve germination percentage of flue-cured tobacco,curtail germinating time,increase matter accumulation,decrease growth differentia and disease incidence rate of flue-cured tobacco seedlings.


Transverse section about several types of animal fur were done and observed,discussed the pros and cons of transverse section morphology,and popularized such qualitative methods.The observation results were shown that there were unique characteristic for the fibers of different animals and clear difference on the their inner ultra structure.The observation results also provide a reliable basis for the discrimination of different fibers and the distinguish of the animal-generic.


This study was made to identify and photograph the foul-weather coronas occurring on a high-voltage transmission-line conductor and to establish their radio-noise importance. On the most tested 230-kV line, snow impingement plumes caused radio interference (RI) to 90 times, and water drop spray plumes to 75 times, that of the base fair-weather noise level. Foul-weather RI caused by snow, rain, fog, ice, and condensate associated with the conductor overrode RI generated on insulators, accessories, hardware, and weathered conductor protrusions. H/sub 2/0 particles in different forms were present in the conductor environment for one-fifth the yearly time. The conductor surface gradient, the rate of decay outward from the conductor, the total conductor surface area, H/sub 2/0 particle size and formation, and air velocity over the conductor are important to both particle attachment to the conductor and to the severity and form of corona. This corona occurs as plumes, impingement plumes, spray plumes, glows, and microsparks. Confirming laboratory tests were made at 230 and 345 kV. Confirming observations were made on 345-and 500-kV lines. Corona losses were caused by impingement plumes during snowstorms and principally by spray plumes in rain.


Dimensionality reduction is an essential feature to reduce the complexity of the computations in the large data set environment. When handling large quantum of medical data set, as in the case like, Lung cancer prediction, based on symptoms and Risk factors, number of attributes/ dimensions pose a major challenge. Here in this study an attempt is made to compare the performance of the attribute selection models prior and after applying the classifier models. A total of 16 classifier models are chosen, which are based on statistical, rule based, logic based and artificial Neural network approaches. Feature set selection and ranking of attributes are done based on individual models. Confusion matrix of the models before and after dimensionality reduction is computed. Based on the confusion matrix result the models are compared and based on the performance optimal model is chosen. It is found that Multi-layer perceptron based artificial neural network model gives better performance compared to other approaches.


With the arrival of big data era, cloud storage has become more ubiquitous. A growing number of consumers remote their data into cloud, as cloud can provide them with ample storage space and powerful computational capacity. However, storing data in cloud means that data is out of their control. How to verify the integrity of stored data and retrieve the corrupted data has become an urgent security problem. In this paper, we propose a new efficient proof of retrievability scheme, named as IPOR, for cloud storage systems. The IPOR not only can verify the integrity of remote data, but also can retrieve the original data of corrupted blocks from the healthy servers with probability 100%. Moreover, IPOR obviously decreases the complexity of data integrity tags and it requires performing a few multiplication and addition operations to retrieve the corrupted data. Therefore, our scheme is much more efficient than the state-of-the-art schemes. In addition, the security analysis indicates that our scheme is provably secure.

Introduction The Utrecht Diabetes Project (UDP) is a shared‐care project providing remote diabetologist support for 85 GPs. In the UDP all examinations, performed by the GP, follow standardized procedures, results being sent to the diabetologist. Laboratory results are sent automatically to both GP and diabetologist.


The research is based on the analysis of treatment of 30 patients (during 2002-2010 years) with. Monteggia injuries by transosseous osteosynthesis. The aim. of the work was to show opportunities of transosseous osteosynthesis as mini-invasive method that allows to restore anatomical structures of injured segment by closed method. Separate fixation of radial and ulnar bones used in the work allowed to remove fixator from the radial bone without losing rigidity of fixation of ulnar bone and. to provide the opportunity of earlier development of rotation. At the estimation of effectiveness of treatment we considered functional activity of injured upper extremity in addition to the result of clinical and. radiologic examination of the patient. The accent was made on the typical mistakes at the treatment of these patients. Study of outcomes of treatment showed that 13 patients (86,6 %) had. usual degree of social integration in 6 months, 2 patients (13,4 %) had. slight limitations of social life. In a year all patients were considered socially integrated.


This paper essentially presents the last and important steps in the study of (practical) solvability of two-dimensional product-type systems of difference equations of the following form z n = α z n - k a w n - l b , w n = β w n - m c z n - s d , n ∈ N 0 , where k , l , m , s ∈ N , a , b , c , d ∈ Z , and where α , β and the initial values are complex numbers. It is devoted to the most complex case which has not been considered so far (the case k = l = s = 1 and m = 3 ). Closed form formulas for solutions to the system are found in all possible cases. The structure of the solutions to the system is considered in detail. The following five cases: (1) b = 0 ; (2) c = 0 ; (3) d = 0 ; (4) a c ≠ 0 ; (5) a = 0 , b c d ≠ 0 , are considered separately. Some of the situations appear for the first time in the literature.


Açaí palm (Euterpe oleracea Mart.) is a native palm tree from the Eastern Amazon, Brazil. It is considered an economically viable source of anthocyanins for the dye and medicine industries. This study aimed to estimate the phenotypic variability and to select genotypes for genetic improvement. Descriptive statistics were used to estimate phenotypic variability. Truncated selection was performed for fruit production per bunch. The collected samples presented the highest fruit yield per cluster of all studied region. Number of fruits per cluster and stem circumference are possibly controlled by few genes. longitudinal fruit diameter may have recessive genes that are decreasing fruit size. Fruit weight, seed weight, pulp weight, number of stem per plant, total cluster length, fruit weight per cluster and pulp yield per fruit presented frequency distribution in favor of heterozygotes. There some characteristics controlled by few genes, with evidence of selection and spontaneous domestication of the matrices.


The main contribution of this paper is to develop a general methodology to solve a class of optimal nonlinear control problems with a single input based on a state-dependent Riccati equation. For a polynomial system of order n the paper proposes a formula for the dependence of the cost-to-go function on one of the variables, which then leads to a state-dependent Riccati equation that is linear in in the remaining unknowns. Furthermore, it is shown that the optimal cost-to-go function is also a Lyapunov function that can be used to prove stability of the closed-loop system. The relevance of the proposed methodology is illustrated in several examples for which analytical solutions are found, including the Van der Pol oscillator, a mass-spring system, and a nonlinear system in strict form.


In recent years there has been a steady decline in the number of applications filed for full-time admission to American Bar Associationapproved law schools. This study sought to determine what explains interinstitutional variation in application volume for the years 1993 to 1996. Using multivariate regression analysis, the study tested a predictive model that incorporates three institutional characteristics (reputation, tuition, and the starting salaries of graduates). The mode was tested for classes entering law school in the fall of 1993, 1994, 1995, and 1996, with numbers of law schools between 169 in 1994 and 1994 to as high as 176 for 1993. Findings show that more than 70% of the variation in volume can be explained. Differences between public and private law schools are reported. The paper concludes with recommendations for increasing application volume. An appendix contains three tables of detailed study data. (Contains 11 tables and 21 references.)

Ferrous sulfate is the most commonly used drug for treatment of iron deficiency anemia, but it is badly absorbed and causes many unfavorable side effects. Nanotechnology is a way to decrease the side effects of drugs and to increase the drug bioavailability. So, this study is designed to investigate the effect of iron oxide nanoparticles in comparison to ferrous sulphate in the treatment of iron deficiency anemia in rats. Forty male albino rats were divided into two main groups:  Control group (10 rats) and anemic group (30 rats) that received standard iron free basal diet for six weeks. Then the anemic group was subdivided into three groups (10 rats) in each group:  anemic control group, ferrous sulfate group (received ferrous sulfate 0.4 mg/kg b.w/ 10 days) and iron oxide nanoparticles group (received iron oxide nanoparticles 0.4 mg/kg b.w/ 10 days) in the drinking water. Iron oxide nanoparticlescaused a significant increase in the level of red blood cells (8.80±0.05 106/µL), hemoglobin (18.46±0.33 g/dL), hematocrit (46.66±0.23 %), mean corpuscular volume (MCV) (53.02±0.3 FL), mean corpuscular hemoglobin concentration (MCHC) (39.56±0.6 %), ferritin (447.6±9.02 µg/L), transferrin saturation (138.0±1.5), total iron binding capacity (TIBC) (145.00±1.15 mg/dL) and serum iron (276.33±2.07 mg/dL). Moreover, it decreased serum malondialdehyde (MDA) (31.85±0.34 nmol/g) and C-reactive protein (CRP) (312.66±1.7 mg/L) when compared to ferrous sulfate group and anemia control groups. These results revealed that iron oxide nanoparticles proved as an effective drug for the treatment of iron deficiency anemia in rats.


Earthquakes are a natural calamity, feared by most and cause great destruction in and around the seismic zone where they occur. In seismic design of buildings, the earthquake motions are considered in principle directions of building which may not be true in all cases. The present study is focused on the earthquake incidence angle and its effect on the structure's column axial force and to obtain the critical angle using Non Linear Time History Analysis. A set of values from 0 to 90 degrees, with an increment of 10 degrees, have been used for angle of excitation. An asymmetrical structure of 10 storeys was considered. It can see that the critical angle may vary the column axial force from column to column. The models are analysed using ETABS 15 software. The structural parameters such as column axial force, displacement and story shear in columns are studied. The paper concludes that the internal forces of structural elements depend on the angle of incidence of seismic wave data. There are different critical angles for different parameters, not necessarily that it should be the same of the column axial force. Keywords— Incidence angle, Non Linear Time History, Column axial force, Displacement, Story shear.


Right Ventricular (RV) strain and 3D RV ejection fraction sensitivity and specificity has made it a practical and reliable test to detect Acute mountain sickness. All previous studies have been done mainly using M Mode and 2D Echo. Hence it was conceived that 3D Echocardiography would be a better option. Regardless of the type of Acute Mountain Sickness (AMS), the echocardiographic evidence is always the same: Severe Pulmonary hypertension. The visual analysis of these abnormalities requires a trained operator. This operator-dependence has promoted the search for a semiautomatic method to reduce limitations of Echocardiography and improve test accuracy

 The purpose was to study AMS by 3D Echocardiography

 Two dimensional echocardiography with RV strain analysis by speckle tracking echocardiography along with 3D RV ejection fraction was done in nine patients with AMS who were tourists on unplanned, unacclimatized assent to Pangong lake, situated near Leh-Ladakh in the Himalayas, approximately at the height of 4350 meters above sea level and six highlanders, living in Leh-Ladakh. Figure 1A shows the map of the Pangong Lake, B. Shows features of Acute Pulmonary Edema in the Chest X-ray from a patient with AMS, C. Shows the TAPSE (Tricuspid Annular Plane Systolic Excursion) D. Shows the Speckle tracking derived RV Free Wall strain (From a software made for LV) and E: Methodology to derive 3D RV Ejection Fraction. 3D Echocardiographic Equipment with LV strain (which was modified to derive RV Free wall strain) and 3D RV Ejection Fraction software was used for acquisition of images and offline analysis was done. TAPSE, FAC, RV Free wall strain, RV EDV index, RV ESV index and 3D RV EF were consistently lower in patients with AMS than in persons living in high altitude (High landers) Table 1

 Strain or myocardial deformation analysis based on two-dimensional (2D) speckle tracking and 3D RV ejection fraction is feasible even in the remote altitudes and allow accurate quantification which has resulted in a growing interest to introduce this new technique in analysis of acute mountain sickness.


A major concern in landscape management and precision agriculture is the variable-rate application of herbicides in order to reduce herbicide treatment load. These applications require a correct assessment and knowledge of the density and potential spatial variability of weed species within fields. This article addresses the issue of incorporating a digital elevation model as secondary spatial information into the mapping of main weed species present in two sunflower crops in Andalusia, Spain. Two prediction methods were used and compared for mapping weed density for precision agriculture. The primary information was obtained from an intensive grid weed density sampling and the secondary spatial information, e.g., elevation from a digital elevation model. The prediction methods were two geostatistical algorithms: ordinary kriging and kriging with an external drift, which takes into account the influence of landscape. Mean squared error was used to evaluate the performance of the map prediction quality. The best prediction method for mapping most of the weed species was kriging with an external drift, with the smallest mean squared error, indicating the highest accuracy. The results showed that kriging with an external drift with elevation reduced the prediction variance compared with ordinary kriging. Maps obtained from these kriged estimates showed that the incorporation of a digital elevation model as secondary exhaustive information can improve the accuracy of predicted weed densities within fields. These results suggest that kriging with an external drift of weed density data with elevation as a secondary exhaustive variable could be used in such situations, and in this way, the accuracy of maps for precision agriculture, which is the preliminary step in a precision agricultural management program, could be improved with little or no additional cost, since a digital elevation model could be obtained as part of other analyses.


To allow a pragmatic approach to understanding value of knowledge as a 'thing' to be transferred, the axiological foundationalism significance of the human perception of knowledge continues to be a significant contributing factor. Similarly the construct of our knowledge is parallel to doxastic attitudes and perspectives. Thus, through reconciliation of foundational and doxastic positions, one can view knowledge and knowledge value as a singular construct. This can be characterised through a multitude definition but not as a singular epistemic principal. This interpretation of current and historical literature offers an outline and assessment of current and historical knowledge philosophy, theory and positioning, but at the same time, tries to place it within the realms of a business context.


We study the phase separation of water and oil in a water-oil-surfactant microemulsion, from a totally disordered phase in two dimensions by means of the cell dynamical system (CDS) simulations on the basis of the time-dependent Ginzburg-Landau (TDGL) model with two order parameters. From our results of the bicontinuous and droplet patterns, the scaling law and the Porod's law of the structure factor are observed.


The International Journal of Rural Management (IJRM) is committed to engaging with its global audience, contributing authors of the current and past issues, reviewers, editorial review board members and all other stakeholders. The journal aims to bring forward innovative thinking to build the field of rural management and to make it more useful for researchers as well as practitioners. The objective of this editorial is to highlight the topic of social entrepreneurship as a fertile area of potential research and briefly introduce the contents of the current issue. The 1980s saw the emergence of entrepreneurship as a significant area of interest among management and social science researchers. Historians, however, would argue that the interest in this area dates back to the 1940s with Joseph Schumpeter's work describing entrepreneurs as agents of change. The 1950s and 1960s saw the concept of organizational entrepreneurship being explored in the works of Arthur Cole, Edith Penrose and Alfred Chandler. Late in the 1990s, social entrepreneurship became recognized as an area of study by academia. Nicholls (2006) reports that banks introduced the term Social Entrepreneur in 1972 suggesting that businesses or managerial practices can also address social problems. Practical relevance and recognition of social entrepreneurship grew with increased media attention on successful social entrepreneurs like Bill Drayton of Ashoka, Muhammad Yunus of Grameen Bank and Jeffrey Skoll of eBay and founder of Skoll foundation. Social entrepreneurship is a multidisciplinary concept that challenges economic and business assumptions. The traditional notion of entrepreneurship assumes that commercial profit maximization is the key motivation behind entrepreneurial success and that entrepreneurship primarily occurs in a market-driven context. However, this notion has witnessed a paradigm shift and there is a growing acceptance of 'more than profitmission driven' businesses. In other words, entrepreneurs need not be solely profitdriven. Rather, they can be mission driven and profit then becomes a byproduct. On the other hand, there are social entrepreneurs running not-for-profit organizations who are driven solely by a mission and do not expect any economic profit. Hence, the realm of social entrepreneurship now includes mission-driven not-for-profit as well as for-profit organizations. Much of the initial literature in this area has focused on defining the social entrepreneurship concept. A popular definition, given by Dees (1998, 4), defines social entrepreneurs as 'change agents in the social sector, by (i) adopting a mission to create and sustain social value (not just private value); (ii) recognizing and relentlessly pursuing new opportunities to serve that mission; (iii) engaging in a process Editorial


In this article, I argue that the Canadian government's position against screening for hepatitis C virus (HCV) and publicly funding HCV treatment is ethically unjustifiable. Cost of medication and likelihood of widening existing health inequality are the government's argument for not funding HCV treatment and for also not having a screening program. I object to this position and argue in favour of a screening program and public funding of HCV treatment. I argue that these barriers are ethically unjust. Conclusively, being denied screening and early treatment is to be denied the best possible outcome.


On the basis of its external morphology, Myotis tricolor (Temminck, 1832) should be able to both aerial-feed and glean. Furthermore, this bat is known to use broadband calls of short duration, reinforcing the prediction that it gleans. However, results from this study indicate that M. tricolor does not commonly glean. This conclusion was reached after studying the foraging behaviour of M. tricolor in a flight room. We presented M. tricolor with mealworms, moths, mole crickets, beetles, and cicadas in a variety of ways that required either gleaning and (or) aerial feeding. Although M. tricolor readily took tethered prey, it did not take any of the variety of insects presented to it in a manner that required gleaning. We therefore compared its wing morphology and echolocation calls with those of several known gleaners, Nycteris thebaica E. Geoffroy, 1818, Myotis lucifugus (Le Conte, 1831), and Myotis septentrionalis (Trouessart, 1897), and an aerial forager, Neoromicia capensis (A. Smith, 1829). In a discri...


Objective Salvianolic acid A, a natural polyphenolic ingredient extracted from traditional Chinese medicine, possesses an excellent pharmacological activity against cardiovascular diseases. Herein, therapeutic mechanisms of salvianolic acid A in myocardial infarction were explored through systematic and comprehensive network pharmacology analyses. Methods The chemical structure of salvianolic acid A was retrieved from PubChem database. Targets of salvianolic acid A were estimated through SwissTargetPrediction, HERB, and TargetNet databases. Additionally, by GeneCards, OMIM, DisGeNET, and TTD online tools, myocardial infarction-relevant targets were predicted. Following intersection, therapeutic targets were determined. The interaction of their products was evaluated with STRING database, and hub therapeutic targets were selected. GO and KEGG enrichment analyses of therapeutic targets were then implemented. H9C2 cells were exposed to oxygen‐glucose deprivation/reoxygenation (OGD/R) to mimic myocardial infarction and administrated with salvianolic acid A. Cellular proliferation was assayed via CCK‐8 assay, and hub therapeutic targets were verified with RT-qPCR. Results In total, 120 therapeutic targets of salvianolic acid A in myocardial infarction were identified. There were close interactions between their products. Ten hub therapeutic targets were determined, covering SRC, CTNNB1, PIK3CA, AKT1, RELA, EGFR, FYN, ITGB1, MAPK8, and NFKB1. Therapeutic targets were significantly correlated to myocardial infarction-relevant pathways, especially PI3K-Akt signaling pathway. Salvianolic acid A administration remarkably ameliorated the viability of OGD/R-induced H9C2 cells, and altered the expression of hub therapeutic targets. Conclusion Our work uncovers therapeutic mechanisms of salvianolic acid A for the treatment of myocardial infarction, providing a new insight into further research on salvianolic acid A.


A visual servo architecture with closed loop control was developed for neurosurgical robot systems to provide high positioning accuracy for delicate surgical operations.The system uses a high precision optical tracking device with the robotic system to provide feedback on the position and orientation of the robot end-effector in real time.Visual closed loop control is accomplished by integrating the joint positioning control with dynamic pose feedback compensation.Simulations show that the method effectively eliminates the affects of parameter variations and corrects for positioning and tracking errors,thus noticeably improving the path tracking accuracy and system robustness.The absolute positioning accuracy is ±1 mm with enabled satisfactory implementation of the system.


A new approach to false alarm recognition is proposed. The described method divides the state of a system into three types: normal, false-alarm, and faulty, and analyzes the overlapping relations of the distribution functions of different states to determine the optimal thresholds. After a brief introduction to support vector machine (SVM), the proposed strategy based on the results using thresholds is explained. The presented evolutionary approach is illustrated by a fault injection system. The accuracy of the technique is compared with the conventional and other intelligent methods, and the obtained results are discussed.

Carbon nanotubes have attracted significant attentions as novel one-dimensional nanomaterials due to their unique structures and properties. Aggregate properties of Carbon Nanotubes (CNTs) such as high surface area, length or surface chemistry are further tailored to enhance their potential application in nanomedicine through post synthesis chemical modifications. These modifications simultaneously alter their aggregate physicochemical properties and this may have a direct impact on cytotoxity of CNTs in cells. Herein, as prepared Multiwalled Carbon Nanotubes (MWCNTs), were initially acid oxidized using strong acids at different temperature to remove impurities whilst introducing carboxylic groups on to the surface. The drug riluzole was then conjugated to the oxidized MWCNTs via carbodiimide activated amidation. Characterized physicochemical properties i.e. length, surface area, degree of functionalization and amount of chemical impurities were key determinants of the drug loaded MWCNTs' cytotoxicity. Covalently linking riluzole to MWCNTs and the consequent changes in the physicochemical properties did not lead to the generation of toxic effects in cells. Furthermore chemically binding riluzole to the MWCNTs did not deactivate the drug and reduce its ability to be antiglutamate. The identification of specific physicochemical properties governing CNT toxicity presents the opportunity for CNT based drug delivery system designs or applications that reduce human and environmental impacts.

Warmer and drier conditions in temperate regions are increasing the length of the wildfire season. Given the greater fire frequency and extent of burned areas under climate warming, greater focus has been placed on predicting post-fire tree mortality as a crucial component of sustainable forest management. This study evaluates the potential of logistic regression models to predict post-fire tree mortality in Korean red pine (Pinus densiflora) stands, and we propose novel means of evaluating bark injury. In the Samcheok region of Korea, we measured topography (elevation, slope, and aspect), tree characteristics (tree/crown height and diameter at breast height (DBH)), and bark injuries (bark scorch height/proportion/index) at three sites subjected to a surface fire. We determined tree status (dead or live) over three years after the initial fire. The bark scorch index (BSI) produced the best univariate model, and by combining this index with the DBH produced the highest predictive capacity in multiple logistic regression models. A three-variable model (BSI, DBH, and slope) enhanced this predictive capacity to 87%. Our logistic regression analysis accurately predicted tree mortality three years post fire. Our three-variable model provides a useful and convenient decision-making tool for land managers to optimize salvage harvesting of post-fire stands.


Ruscodibenzofuran (2-acetyl-6,9-dimethyldibenzofuran-3-ol) has been synthesized by condensation of 2,4,7-trimethylbenzofuran-3-carbaldehyde with Meldrum's acid, flash vacuum pyrolysis of the condensation product (8), and overall C-acetylation of the resulting 6,9-dimethylbenzofuran- 3-ol.


Matings and crosses within and among geographically different populations of the pearl oyster,Pinctada martensii(Dunker)were carried out in orde r to breed new strains for pearl culture.Six populations of the first filial gene ration have been obtained.Three population designated BB 1,DD 1,and SS 1 were from matings of wild populations of Beihai(BW),Daya Bay(DW),and Sanya(SW).T hree populations,BD 1,SS 1,and DS 1 were from cross between BW and DW,BW and SW,and DW and SW respectively.P.martensii (Dunker) was a susceptible oyster to be infested by poly- chaetes.The infestation rates were 66 7%~75 5% in 6 populations of the first filial generation.There were no significant differences in infestation rates between male oysters and female oysters(P0 05).In t he same population,infestion rates in double valves of a oyster were significantly higher than in single valve(P0 05),and the main morphological traits,s hell length,shell width,total weight and shell weight did not appear significant differences between non-infested oysters and infested oysters (P0 05).Th e h armfulness of polychaete infestation would lead to high mortality of the pearl o ysters.The infestation rates in crossing filial populations,DS 1 and BD 1 decreased by 8 4% and 8 8% respectively in comparison with self mating popultion BB 1 (P0 05).The reduced infestation rates in DS 1 and BD 1 vs BB 1 showed that some resistance to polychaete could be gained from cross between populations.


Dialogue has been of decisive importance for European culture and ist dynamics. It goes back to Plato's attempt to escape from illusion and to gain substandtiative htwoledge by means of cooperative thought. A comparison with Buddhism and Taoism parmits the particular quality inherent in the dialogue culture to becom probable. The destruction of dialogue culture is a problem which even Plato had to tackle. It is pointed out that even today public dialogue is in danger, due to the language of politics being for removed from dialogue and to the solely pragmatic orientation of the ethics of genetic technology.


This paper develops a design methodology for a trigeneration system that employs renewable energy sources (biomass and solar energy). The structural scheme trigeneration required to cover the demand of a house has been determined according to the amount of energy used by this house. Correlating the demand and the energy production, the power sources are determined in order to minimize heat losses and to maximize the primary energy savings as well as the overall efficiency of the system. According to a structural scheme, the functional trigeneration system that enables to determine the internal consumption of electricity of the power pumps is developed. This methodology is proven through the achievement of a practical system of trigeneration. The system that has been implemented contains a Stirling engine, photovoltaic panels for the production of electricity, solar thermal panels and an auxiliary boiler for heat production. In residential areas, in summer, the desired temperature is achieved through the use of an adsorption chiller unit.


Basic glasses of Li_2O-Al_2O_3-SiO_2 system with P_2O_5 as nucleation agent were prepared by means of conventional melt quenching technology, and the heat-treatment conditions were determined by using DTA. The glass-ceramics with very low thermal expansion coefficient were obtained at different heat-treatment temperatures. The crystalline pha- ses, the microstructure of the glass-ceramics and the influence of heat-treatment on the structure and the thermal properties of the glass-ceramics were investigated according to the X-ray diffraction analysis and the SEM. The results show that the basic glasses in the Li_2O-Al_2O_3-SiO_2 system may be prepared at lower melt temperature and the low expansion glass-ceramics of Li_2O-Al_2O_3-SiO_2 system can also be obtained at different heat-treatment temperatures. The main crystal phase is β-quartz but this crystal grows slowly at the initial crystallization temperature, while β-eucryptite and β-spodumene grow rapidly at higher heat treatment temperature.


We revised the section Hololeuce Bunge of the genus Astragalus L. (Leguminosae) in Turkey. The section used to contain 20 taxa in Turkey, but in this study it has been reduced to 15. A new species (Astragalus dumanii Ekici & Aytac) has been described. In addition, we concluded that A. vuralii H.Duman & Aytac, A. cylindraceus DC., A. alindanus Boiss., A. paecilanthus Boiss. & Heldr. and A. squalidus Boiss. & Noe are synonyms of A andrasovszkyi Bornm., A. globosus Vahl, A. hirsutus Vahl, A. sibthorpianus Boiss. and A. amoenus Fenzl respectively. The pollen grains are tricolporate, prolate, subprolate or prolate sphaeroidal and the ornamentation is reticulate.


A series of neuroblastoma cell lines were screened for the presence of opioid receptor sites with the tracers [3H]diprenorphine (p , 6, K ligand) and f3H]naloxone (p-selective ligand). One human neuroblastoma cell line, SK-N-SH, displayed avid binding for both tracers. Binding experiments with multiple tracers revealed the presence of both p and 6 sites. These sites were stereospecific, saturable, and proteinaceous in character. Saturation binding experiments provided an estimate of 50,000 and 10,000 6 sites/cell. NaCl (100 mM) and guanine nucleotide, guanylyl imidodiphosphate (50 p ~ ) , reduced opioid agonist but not antagonist binding to these sites. Etorphine at 1 nM inhibited prostaglandin El-stimulated cyclic AMP production by approximately 20%, which was reversible by naloxone. The opioid-binding sites on SK-N-SH cells closely resemble the previously reported p and 6 sites in human and rodent brain. Therefore, the SK-NSH neuroblastoma cell line represents a useful tool to study the molecular functions of opioid receptors.

The study is due to an increase in nonspecific complications in oncological diseases. The research purpose is to study in experiment the features of the formation of nonspecific pathomorphological changes in liver tissue during tumor processes. Research objectives: to simulate toxic hepatitis on the tumor line of mice, to study the effect of the tumor process on pathomorphological changes in the liver with its toxic lesion, to study the effect of a tumor on pathomorphological changes in the liver when using methotrexate, to conduct a comparative analysis of the results and identify the features of the formation of nonspecific changes in liver tissue. Materials and methods. We conduct the study on mice of the Balb/c line. The work was carried out according to the recommendations set out by the Ministry of Health of the USSR no. 755 of August 12, 1977 and the Helsinki Declaration. We form a control group, a comparison group and an experimental group. In the comparison groups, carbon tetrachloride 0.1 ml of 40 % solution and methotrexate at a dosage of 0.2 mg were administered intraperitoneally to animals. The experimental group included animals with formed malignant tumors. Main results. Pathomorphological changes indicate the progression of nonspecific necrobiotic, cholestatic, inflammatory and microcirculatory processes under the influence of a hepatotropic agent. When using cytostatics, necrobiotic, cholestatic and microcirculatory changes progressed without a cellular reaction. Conclusion. The revealed pathomorphological features in the liver tissue indicate the pathogenetic significance of toxic liver damage leading to the progression of liver failure in tumor processes.

Published online: June -2020 Abstract: Purpose: This study aimed to investigate effect of moderate Aerobic Exercises on Liver Function in Non-Alcoholic Fatty Liver Disease in University Students Methods:sixty patients with non-alcoholic fatty liver disease (NAFLD) with age ranged from 18-28 years old from both sexes.Patients were divided into two equal groups; group A received their standard medications associated with low calorie diet and moderate aerobic exercises 3 times per week for 8weeks while group B received their standard medications and low calorie diet for 8 weeks. Lab investigations of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and triglycerides (TG) were applied to evaluate patients. Fatigue severity scale (FSS) and body mass index BMI were calculated for patients at two intervals (pre-treatment and posttreatment). Results: there were significant improvement of all variables post-treatment compared to pre-treatment in group (A) with improvement percentage in BMI (8.6%), ALT (15.97%), AST (16.3%), TG (17.99%) and FSS (35.38%). In (group B): there were significant improvement of all variables post-treatment compared to pre-treatment in BMI (5.9%), ALT (11.4%), AST (7.68%), TG (11.15%) and FSS (5.66%). Moreover, there were no significant difference in BMI, ALT, AST and TG between both groups. However, there was significant difference in FSS in favor of group A. Conclusion: moderate aerobic exercises are not effective strategies in management of liver function of non-alcoholic fatty liver disease in university students when low calorie diet is a part of standard treatment of low calorie diet. Furthermore, aerobic exercise is effective method for improvement fatigue level.


BACKGROUND
This study aimed to develop and validate an easy-to-use ICU illness scoring system to evaluate the in-hospital mortality for very old patients (VOPs, over 80 years old).

METHODS
We performed a multicenter retrospective study based on the eICU Collaborative Research Database (eICU-CRD), Medical Information Mart for Intensive Care Database (MIMIC-III CareVue and MIMIC-IV), and the Amsterdam University Medical Centers Database (AmsterdamUMCdb). Least Absolute Shrinkage and Selection Operator (LASSO) regression was applied to variables selection. The Logistic regression (LR) algorithm was used to develop the risk score and a nomogram was further generated to explain the score.

RESULTS
We analyzed 23,704 VOPs, including 3,726 deaths (10,183 [13.5% mortality] from eICU-CRD (development set), 12,703 [17.2%] from the MIMIC and 818 [20.8%] from the AmsterdamUMC (external validation sets)). Thirty-four variables were extracted on the first day of ICU admission, and 10 variables were finally chosen including Glasgow Coma Scale, shock index, respiratory rate, partial pressure of carbon dioxide, lactate, mechanical ventilation (yes vs. no), oxygen saturation, Charlson Comorbidity Index, blood urea nitrogen and urine output. The nomogram was developed based on the ten variables (AUC: training of 0.792, testing of 0.788, MIMIC of 0.764 and AmsterdamUMC of 0.808 [external validating]), which consistently outperformed the SOFA, APS-III, and SAPS-II.

CONCLUSIONS
We developed and externally validated a nomogram for predicting mortality in VOPs based on 10 commonly measured variables on the first day of ICU admission. It could be a useful tool for clinicians to identify potentially high risks of VOPs.


The small field‐of‐view (FOV) limits the range of vision in various detecting/imaging devices from biological microscopes to commercial cameras and military radar. To date, imaging with FOV over 90° has been realized with fish‐eye lenses, catadioptric lens, and rotating cameras. However, these devices suffer from inherent imaging distortion and require multiple bulky elements. Inspired by compound eyes found in nature, here a small‐size (84 μm), distortion‐free, wide‐FOV imaging system is presented via an advanced 3D artificial eye architecture. The 3D artificial eye structure is accomplished by exploiting an effective optical strategy — high‐speed voxel‐modulation laser scanning (HVLS). The eye features a hexagonal shape, high fill factor (FF) (100%), large numerical aperture (NA) (0.4), ultralow surface roughness (2.5 nm) and aspherical profile, which provides high uniformity optics (error < ±6%) and constant resolution (FWHM = 1.7 ± 0.1 μm) in all directions. Quantitative measurement shows the eye reduces imaging distortion by two/three times under 30°/45° incidence, compared with a single lens. The distortion‐free FOV can be controlled from 30° to 90°.


OBJECTIVE To study the distribution and drug resistance of the pathogens isolated from the bile during 2009-2011 so as to provide basis for the prevention and control of nosocomial infections.METHODS A retrospective analysis was performed for the microbial culture and drug susceptibility testings for the bile specimens collected from patients who received the biliary tract surgery or ERCP procedure from 2009 to 2011.RESULTS Totally 723 strains of pathogens were isolated during 2009-2011,the gram-negative bacteria were the major pathogens causing biliary tract infections,which accounted for 68.74%,with the number of 497 strains.There were 179(24.76%) strains of gram-positive cocci and 47(6.50%) strains of fungi.The imipenem,meropenem,and amikacin had a great anti-bacterial activity against Enterobacteriaceae,with the drug resistance rate of less than 3.00%,and the drug resistant rates were less than 15.00% to piperacillin/ tazobactam,cefoperazone/sulbactam and cefoxitin;the drug resistance rates of Pseudomonas aeruginosa were less than 30.00% to all the antibiotics except meropenem,Enterococci were susceptible to vancomycin,linezolid and nitrofurantoin,and there was no significant change in the drug susceptibility in the recent three years.CONCLUSION The distribution and drug resistance of the pathogens causing the biliary tract infections did not change significantly in the three years,the gram-negative bacteria are the predominant pathogens,followed by the gram-positive Enterococci.The carbapenems,aminoglycosides,cephamycins,β-lactamase enzyme inhibitors,vancomycin,and linezolid have high antibacterial activity.It is still very important to monitor the drug resistant and to reasonably use antibiotics.


Study on the minority students' beliefs in universities is an important measure to strengthen and improve the student's ideology and politics education and practice the party construction and also important work on the direction of students' communist ideal.In the respect of belief education,universities should insist the political direction of communism and public opinion direction,increase the charm of belief theory itself,innovate the belief education theory,wake up the rational needs for belief of the students,work hard on the campus spiritual culture,connect with belief education and play the main role of the class of ideology and politics.


A EUROPEAN perspective to the current debate on the nature of archaeology and its relationship with history is given. Whilst some of the concepts are complex, it is important that medieval archaeology recognizes its importance as a field of research likely to yield valuable insights into the nature of archaeological data, the ways in which inferences about the past can be drawn, and the similarities and differences between archaeology, anthropology and history.


The poetry of Arthur Hugh Clough has tended to be read in dialogue with the writings of his friend and critic, Matthew Arnold. This essay explores how bringing Clough's work into conversation with that of a very different friend, Ralph Waldo Emerson, offers to cast his intellectual affinities and poetic technique in a new light. Interweaving close readings of Clough's verse with detailed attention to the essays he is known to have read and admired, I trace how Clough adapts and revises Emerson's critique of 'knowingness'. Beginning by tracing the history of this term in nineteenth-century literature and culture, I argue that Clough's Dipsychus shapes an Emersonian ethic and aesthetic of encounter as an alternative to complacent and proprietorial forms of knowing. Turning to the rest of Clough's oeuvre, especially Amours de Voyage, I then consider how fantasies of the future are central to what it means to be knowing about oneself, and examine how Clough applies poetic pressure to Emerson's conviction that 'A man … never rises so high as when he knows not whither he is going'.

Objective:To analyze the effect of infertility hydrocephalus in use.Methods A retrospective analysis was made on clinical data of 200cases of women in pregnancy after infertility hydrocephalus in use from July 2004to July 2009in Maternal and Child Health Care Centre of Changji.Results Among the 200 cases of tubal infertility patients through fluid operation,the total fertility rate was 41.00%(82/200).The highest rate of unobstructed pregnancy was two times(52.94%)and the lowest rate of unobstructed pregnancy was 3times 20.00%);through liquid 1~3months after the pregnancy rate was 57.78%,1year or more liquid through the lowest fertility rates(23.08%).Primary infertility and secondary infertility,pregnancy rates had no significant differences(P0.05).Conclusion The infertility hydrocephalus is a feasible method not only for diagnose in early sift but also can be a direct cure of infertility.


The immunotherapy is a programming therapy of cancer, so new immunotherapy target genes would be urgently demanded at present. Although The Cancer Genome Atlas Program (TCGA) provided more than 11,000 patients' multi-omics data of more than 33 cancers, the heterogeneity of tumor tissue may still mask the immune-associated gene differential expression. In our study, to address the heterogeneity masked by the bulk RNA-Seq, TCGA data were first dividend into 26 types cancers by their high immune infiltration and low immune infiltration through single-sample gene set variation analysis to detect immune-associated gene, and single-cell RNA-Seq were than reanalyzed to prove the result we received in RNA-Seq. In order to verify our result in cell lines, a series of experiments were performed on two different microsatellite state cell lines: HCT116 (microsatellite instability high) and HT29 (microsatellite stability) because of colorectal cancer had its corresponding cell lines. Our results suggested that high expression levels of CD58, an immune-related gene, was masked by the bulk RNA-Seq and had a significant effect on the prognosis of patients with microsatellite instability high. The high expression of CD58 inhibited the proliferation and invasion of cancer cells in HCT116, which had highly unstable microsatellites, but had no effect on HT29, which had stable microsatellites. The high CD58 expression combined with microsatellite instability high statuses were the important molecular targets in the selection of immunotherapy methods in colorectal cancer. In short, our study provides new insight into detecting immune-associated gene in different cancer bulk RNA-Seq.

This paper describes my submission to one of the sub-problems formulated for the Predictive Toxicology Challenge 2001. The challenge is to predict the carcinogenicity of chemicals based on structural information only. I have only tackled such predictions for bioessays involving male rats. As we currently do not know the true predictions for the testset, all we can say is that one of the models supplied by us seems to be optimal over some subrange of the ROC spectrum. The successful model uses a voting approach based on most of the sets of structural features made available by various other contestants as well as the organizers in an earlier phase of the Challenge. The WEKA Machine Learning workbench served as the core learning utility. Based on a preliminary examination of our submission we conclude that reliable prediction of carcinogenicity is still a far away goal.


The presence of foreign bodies in packaged food is a serious concern for both final consumers (allergies, injuries, choking) and food manufacturers (reputation and economic losses). In particular, low-density plastics, glass and wood splinters are hard to detect even by the most advanced X-ray imagers. One solution is Machine-Learning-based Microwave Sensing (MLMWS): a non-invasive, contactless, and real-time method which uses a machine-learning (ML) classifier to analyze the scattered microwaves from the irradiated target object. In this paper, we want to extend our previous work about contaminant detection in cocoa-hazelnut spread jars by proposing an enhanced ML flow to increase the accuracy of the ML classifier. For the first time in this case study, we use a multi-class classifier, we train it with scattering parameters measured at multiple microwave frequencies, with a new pre-processing scaler, data augmentation, quantization-aware training and a pruning schedule. The results show a contaminant detection multi-class accuracy of 94.167% with a latency of $26 \mu s$ when targeting an AMD/Xilinx Kria K26 FPGA. Finally, we released our datasets publicly to OpenML.11Fermilab report number: FERMILAB-PUB-23-313-PPD


The present paper is devoted to investigation of the isometry group of the Gromov-Hausdorff space, i.e., the metric space of compact metric spaces considered up to an isometry and endowed with the Gromov-Hausdorff metric. The main goal is to present a proof of the following theorem by George Lowther (2015): The isometry group of the Gromov-Hausdorff space is trivial. Unfortunately, the author himself has not publish an accurate text for 2 years passed from the publication of draft (that is full of excellent ideas mixed with unproved and wrong statements) in the this https URL blog (see the exact reference in he bibliography).


Following the Khartoum World Health Organization (WHO) Seminar on Traditional Practices Affecting the Health of Women and Children held during February 1979 a voluntary association was formed The Babiker Badri Scientific Association for Womens Studies with one of its objective the abolition of female circumcision. This Association is undertaking a 3-year project of village welfare work to include work for the abolition of genital mutilation. The project was initiated in October 1980 and is being financially assisted by the Swedish Save the Children Fund. In line with its commitment to a national campaign against female circumcision the Association has a subcommittee which includes representatives from the Sudan Government Departments. Workshops to further the campaign were held at the General Assembly Buildings in Khartoum during March 1981. Prior to the workshops the Association and many other Sudanese men and women worked hard to ensure the success of the endeavor. Posters were made and special note paper was designed to advertise the need to help. There were several radio broadcasts and television programs about the importance of the work. Thought was given to ways in which to influence public opinion in general to change certain attitudes. The workshops were well attended and the workshop efforts were impressive. Recommendations made from the workshops include the following requests: 1) there shall be government representatives from the Ministry of Health and Education the Higher Council for Social Welfare and Development and the Ministry of Information and Guidance to help the Babiker Badri Association to carry out workshop recommendations; 2) all preachers in Islamic mosques beginning March 13 1981 should preach against the practice of female circumcision; 3) an Annual Celebration should be held for 7 days throughout the Sudan for the campaign against all forms of female circumcision; and 4) the Womens Secretariat of the Socialist Union of the Sudan should incorporate in its plan for literacy campaigns the 2 attacks on illiteracy planned by the Sudan government. It is important that this campaign against the long established custom of female circumcision should not languish but be extended while it is uppermost in the minds of many men and women.


Mid-IR lasers that operate near the absorption peak of water have a short penetration depth in ocular tissues. Ablation of tissue can be accomplished with minimal coagulative damage to underlying structures. We used an erbium:YAG laser equipped with a contact probe to create retinotomy sites in the human retina of eye bank eyes. An erbium:YAG laser (2.94 micrometers ) equipped with an infrared transmitting glass fiber and a sapphire tip (400 micrometers ) was used to directly ablate the surface of the retina. We administered both single and multiple pulses to the macula and peripheral retina using energy levels from 4 to 16 mJ per pulse. The retinas were then examined histopathologically to evaluate the extent of ablation and coagulative damage. Single pulses at low energy levels were noted to cause ablative damage to the nerve fiber layer and ganglion cell layer without a notable coagulative effect. The mean ablation depth at lower energy levels was less than the mean ablation depth at higher energy levels. Extensive laser application produced disruption of the retinal pigment epithelium, choroid and sclera. the erbium:YAG laser equipped with a contact probe is an effective means of creating retinotomies in human autopsy eyes. When used in the single pulse mode at lower energy levels, the erbium:YAG laser appears capable of removing superficial retinal layers without damaging deeper structures.


Abstract Electronic transport in hydrogenated amorphous silicon (a-Si:H) and in hydrogenated amorphous silicon-germanium alloys (a-Si1-xGex:H) has been studied by means of time-of-flight experiments, mainly in the temperature range where the transport is dispersive. It is shown that the use of the pre-transit slope of the current in a plot of In I against In t, in addition to the determination of the transit times, can lead to an estimate of the shape of the density of states. First, we apply this technique to the results of a numerical simulation based on a matrix method; the deduced densities of states agree well with those introduced. Then we apply the method to a sample of a-Si: H, whose density of states had already been deduced using a completely different method based on the Fourier transform of the derivative of the current obtained when the transport is non-dispersive. The agreement between the results of the two methods is excellent. In this a-Si: H sample it is found that the density of tail st...


In this paper,we estimate and analysis the changes of technological progress' rate and the changes of technology contribution during the main stages of economic development of Harbin from 1986 to 2007 with Cobb-Douglas production function model and the Solow growth equation,and note that technological progress has become the main driving force of economic development of Harbin.However,such a driving force of technology on the economy is not stable,and appears significant fluctuations.


This article analyzes neuroimmune linguistic programming as a transversal spiritual axis in living organizations with a human face. It is based on the theories of Punset (2010), Koenig, et al. (2001) and O'Donnel (2000), among others. Methodologically, it was framed in a qualitative, documentary paradigm with a bibliographic design. Findings show studies revealing that what employees want most in their work is a feeling of love and care and some connection between their work and their larger purpose in life. From the perspective of neuroimmune linguistic programming, spirituality can be seen as a management tool for motivation in the XXIst-century leader. It helps to create a better atmosphere in the workplace. It is a vision of positive, optimistic life that improves self-esteem, serving as a transversal, spiritual axis in living organizations with a human face.


A method of describing and optimizing the product process was put forward. Firstly, the product lifecycle model was set up based on DD-RCM. And the model was transformed to control and integration Petri net for confirming all the activities of product process, such as selection, conflict, synchronization and subsequent relation. Then, the reengineering algo- rithm of incident matrix was employed to describe all the activities. Thirdly, the product process was optimized and conformed. At last, the product lifecycle was brought forward as an example to indicate the feasibility and validity of the proposed method.


This work introduce a study resulting from application of data mining in an BM&FBovespa database with companies' results. Companies disclose their indicators into stock market and are used for investors evaluate stocks. Experiments were performed with income statements, balance sheets and price informations. Were used classification algorithms to analize the data generated on the database. The companies were classified as "Weak", "Good"or "Very Good"comparing your incomes with the Selic rate during the studied period. This work presents the classification algorithms used, the attributes generated in the database, graphics and spreadsheets to compare the algorithms performance. With the fundamentalists indicators and data mining algorithms used in the study, was obtained a high rate of correct answers to the "Weak"class, but just a few companies of "Good"class and "Very Good"were classified correctly.


For the three centuries between approximately 900 and 600 B.C., Assyria was the major power of the Near East, ruling over the largest empire the world had ever seen. Having become rich with the spoils of war and tribute of subject nations, Assyrian kings built cities, palaces, temples, and public works as expressions of their power. The abundant monuments and textual records from this period reveal a male-oriented society in which politics, military affairs, religion, and commerce belong primarily to the male sphere of influence. As a result, we are relatively well informed about these kings, the events of their reigns, and the officials who served them, but the women of the period remain obscure. Most Assyrian texts, which were created by men for the public expression of royal ideology (itself inherently male), belong to well-established categories and thus follow strict formulae. Assyrian ideology pervades most textual material and tends to subsume the individual personalities of both men and women in the stock roles it creates for them. 1 With few exceptions, women of the royal household appear in official sources only tangentially. Not only are we denied any access to women as individuals, but even their appointed roles are difficult to discern clearly. For this reason, it is necessary to identify both how the Assyrians ranked women within the domestic quarters, and the way they publicly expressed the status of royal women, before we can determine how women's status acted as a function of royal ideology and a social tool. The Neo-Assyrian kings enjoyed enormous wealth and used it to build-among other things-palaces for themselves and their dependents. The king maintained residences at various cities in Assyria and most of these contained a separate court complex for women. Textual evidence attests to women's quarters in palaces at Nimrud, Nineveh, Kilizi, Tarbisu, Khorsabad, Assur, Ekallate, and numerous other cities around the empire.2 Some of these palaces have been excavated, but it is the artifacts recovered in them, rather than distinctive architectural features, that allow us to identify the women's quarters. Domestic quarters have been located with some certainty at the southwest palace of Sennacherib at Nineveh, the northwest palace of Ashurnasirpal II at Nimrud, and the ekal m~s'arti at Nimrud.3 It was I am indebted to professors Benjamin Foster and Eckart Frahm for reading an earlier version of this paper. Their many corrections and suggestions have been immensely valuable to me, although, naturally, responsibility for any shortcomings in the final product belongs entirely to me.

Almost every computer software system is bound to b e reengineered for at least maintenance purposes at some point and hence reengineering is a s important as any other phase in a system's lifecycle. It is important that both the original d evelopment method and the reengineering approach are chosen to minimise maintenance costs. Since use rs oft n discover that they want features in their system that they have seen in another system, reusa bility nd understandability of the produced code are also important to minimise maintenance.


This paper proposed a robust model predictive control (RMPC) framework for the energy management of isolated microgrids to cope with the uncertainties and the dynamic of various loads and the renewable energy output. A mixed deterministic integer programming model of the energy management of isolated microgrids was firstly proposed with the goal of minimizing the cost of integrated economic operation, then the robust counterpart of the deterministic energy management optimization model was derived. After that, based on the model predictive control (MPC) framework, we proposed an online energy scheduling strategy, in which through adjusting the related settings in the robust optimization, the isolated microgrid can adapt to the various uncertain risks in energy management. At last we used a numeric test to verify the effectiveness of the proposed model and the proposed RMPC framework.


For the most part the extant literature considers abnormal accruals to be opportunistic and discounted by the market. However, an alternative view is that abnormal accruals signal manager's private information of firm value and profitability so are valued positively by the market. In addition, there is evidence that effective corporate governance mitigates opportunistic earnings manipulation. While prior studies have tested for the impact of corporate governance on the value relevance of earnings this study is different in that it focuses on the impact of governance on the value relevance of that part of earnings that are likely to be manipulated: abnormal accruals. Using a sample that is comprised exclusively of accounting data reported under IFRS evidence is provided that the market views abnormal accruals as being on average opportunistic. However, it also perceives this opportunism to be mitigated by effective corporate governance. These findings are robust to alternative ways of measuring abnormal ac...


MIB is a media recorder/player of sound and video handled with a gesture interface. The proposed technique allows users to capture and play audio-visual data by using gesture towards graphical bubbles. A graphical bubble, on which an image captured by a camera is mapped, is generated in real time when a user has captured an audio-visual datum. The captured datum is enclosed with the generated graphical bubble. Thereafter, the user can play/view the data by using gesture of touching and bursting a bubble. This research proposes new gesture-based interface for recording and viewing audio-visual data while playing with bubbles.


Global-openness reflects a willingness to interact with foreign people and cultures, including cultural products. Ethnocentrism is a psychosocial construct depicting the proclivity for individuals to view their own group as superior and to reject that which is culturally dissimilar. The extant research suggests that ethnocentrism should be positively related to consumption of domestic movies whereas global-openness should be positively related to consumption of and desire for watching foreign movies. Data collected from a sample of U.S. moviegoers are used to test these propositions and gather insights into U.S. consumers' cultural choices.


Da'wa efforts in the era of disruption with the presence of online-based new media provide a space of expression for anyone to convey da'wa through unlimited creativity with various innovations. Da'wa is not always delivered seriously in a formal atmosphere but da'wa can be packaged in a relaxed manner, can be enjoyed in a relaxed and even entertaining way. Collaboration between da'wa and entertainment known as da'watainment is expected to be able to attract the millennial generation who are the largest users of Youtube media so that da'wa messages can be packaged through communication media that are close to the world of the millennial generation with concepts that are trending among millennials, one of which is prank. Prank content had gone viral after drawing a lot of criticism and protests because it contained useless substances and actually caused harm. Creative ideas are needed to modify useless content into useful content that is still interesting and entertaining. This study describes qualitatively descriptive from the data obtained from virtual observations on prank content and prank shalawat on Gus Aldi's Youtube channel which inspires millennial da'i-da'i in conveying da'wa messages through Youtube. In this content there is a varied structure in broadcasting shalawat as well as other messages of Islamic teachings which are also conveyed in a humorous, relaxed, and entertaining way.

Iron–tetraamido macrocyclic ligand (TAML) activators have been designed and developed to provide small-molecule mimics, the peroxidase enzymes. Fe–TAML activators are proving to be highly active catalysts that function effectively at very low concentrations from nanomolar to low micromolar. Notably, they are capable of performing many thousands of turnovers per minute under ambient conditions, of functioning over a broad pH range from acidic and most notably for iron catalyst to basic and even to highly basic, of presenting a broad range of selectivities and oxidative aggression determined by the conditions of use and the choice of catalyst over the 14 catalysts presented. The catalysts have fulfilled the design criteria and now provide the basis of platform technology for myriad applications. Published kinetics and mechanistic interpretations are reviewed to illustrate the success of the design protocol. Published applications are briefly described. A highly developed field of use involves the use of Fe–TAML–peroxide for the purification of water of persistent pollutants and hardy pathogens.

Corona viruses ( CoVs) are well-covered RNA viruses that cause enteric and respiratory infections in humans and animals. Many human CoVs have recently gained global interest because of their lethal power and high contagious power. SARS-CoV- 2, or COVID- 19, is a pathogenic coV that first appeared in Wuhan, China. Corona virus Disease 2019 (COVID-19) created by SARS-CoV-2, has been declared as pandemic by the World Health Organization since March 11, 2020. The epidemic started in Wuhan and spread rapidly around the world. Corona virus is facing a major epidemic: Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). SARS-CoV-2 is a virus closely related to SARS. Corona virus (COVID-19) is caused by SARS-CoV-2 VIRUS, a complex clinical disorder characterized by severe pneumonia and acute respiratory stress syndrome. Serious and neurological disorders, such as encephalitis, coma, fever, epilepsy, and Guillain-Barre syndrome, are more common in cases of COVID-19. In addition, chronic autoimmune and neurodegenerative diseases may occur in SARS- CoV-2 immunopathology and colonization of intestinal and central nervous system, as well as systemic inflammatory response during COVID-19. Parkinson's disease is a common neurodegenerative condition that causes the development of motor and non-motor symptoms.


Slip and fall accidents are the leading cause of injuries for all ages, and for fatal injuries in adults over 65 years. Various factors, such as floor surface conditions and contaminants, shoe tread patterns, and gait behavior, affect the slip risk. Moreover, the friction between the shoe outsoles and the floor continuously changes as their surfaces undergo normal wear over time. However, continuous assessment of slip resistance is very challenging with conventional measurement techniques. This study addresses this challenge by introducing a novel approach that combines sensor fusion technology and machine learning techniques to create intelligent insoles designed for fall risk prediction. In addition, a state-of-the-art slip simulator, capable of mimicking the foot's motion during a slip, was developed and utilized for the assessment of slipperiness between various shoes and floor surfaces. Data acquisition involved the collection of pressure data and three-axial accelerations using instrumented shoe insoles, complemented by friction coefficient measurements via the slip simulator. The collected dataset includes four types of shoes, three floor surfaces, and four surface conditions, including dry, wet, soapy, and oily. After preprocessing of the collected dataset, the simulator was used to train five different machine learning algorithms for slip risk classification. The trained algorithms provided promising results for slip risk prediction for different conditions, offering the potential to be employed in real-time slip risk prediction and safety enhancement.


The paper describes direct techniques for the determination of the parameter sensitivity functions of linear closed-loop systems. These techniques, which may be applied both in the time-domain and in the frequency-domain, can yield sensitivity functions of all the output variables with respect to all of the adjustable parameters of the closed-loop system using minimal experimentation and without the need for explicit identification of the controlled system.


LLC resonant converter was wildly used for its high switch frequency and high power density. Its main topology is a second order resonant system whose feature varies with load. Thus, it is equivalent to a nonlinear system. However, it is difficult to satisfy the demand of chargers by using only fixed controlling parameters. The paper uses the fundamental analysis method to build system model, and through adjusts controlling parameters to suit the time varying feature. The experiment result shows the validity of proposed controlling method.


Reconfigurable manufacturing systems are considered to be one of the newer technologies which cannot only meet stochastic product demand but can also produce products having customised variety. The paper presents performance modelling of a reconfigurable manufacturing system equipped with dedicated and reconfigurable machines under the failure of any resource. The dedicated machines are assumed to be subjected to random failures or breakdowns and upon occurrences of such breakdowns or failures, the jobs from these machines are routed or dispatched to reconfigurable machines to carry out the desired operation after suitable reconfiguration. Different dispatching strategies under two production scenarios were simulated using ARENAO discrete event simulation software. Performance of dispatching strategies proposed was analysed in terms of productivity, congestion and make-span time. The results were analysed and were discussed in light of previous researches carried out on the topic.


This ethnographic investigation of a multiethnic, multilingual classroom examines the ways in which immigrant students' goals for community and belonging were mediated by their vibrant cultural and linguistic practices. Findings demonstrate how youth formed a community of practice through brokering acts, resource pooling, and linguistic play across national, cultural, and linguistic differences. As such, immigrant students were agentive transcultural navigators whose practices broach new understandings of social life and learning, and present a pedagogy of possibility. It is argued that immigrant classrooms in contact zones must be reenvisioned – from reductive spaces where educational goals are to acculturate the immigrant into a fading US homogeneous mainstream – to cutting edge spaces of twenty-first-century learning.


In 2010, the U.S. Department of Education announced an initiative to improve transitioning to postsecondary education (PSE) for individuals with intellectual disabilities (ID) by funding the model comprehensive Transition and Postsecondary Programs for Students with Intellectual Disabilities (TPSID) program. The TPSID provides for grants to create or expand inclusive comprehensive transition and postsecondary programs for students with ID. The authors provide a descriptive report of one such TPSID-funded demonstration in the state of Hawai'i and share preliminary feedback from student participants, agency and institutional partners, and project staff. The authors' interviews with the participants and collaborators provided insights and perspectives of the challenges inherent in implementing such a demonstration model. They found that student participants with ID, who were culturally and linguistically diverse, relished the opportunity to participate in PSE and were motivated by the opportunity to learn, meet new people, and contribute to their families. Interagency partners valued the process and benefits of interagency teaming, with most reporting that participating in collaborative teaming resulted in a shift in their views on inclusion of students with ID in PSE. The authors concluded that the implementation of an inclusive PSE transition model can be a transformative process for students with ID, PSE institutions, and support agencies. Furthermore, that collaborative interagency teaming is a powerful method to inform and empower the implementation of change and stimulate and facilitate new opportunities and approaches to improve transition outcomes for students with ID.


Some general remarks are made about the quantum theory of scalar fields and the definition of momentum in curved space. Special emphasis is given to field theory in anti-de Sitter space, as it represents a maximally symmetric space-time of constant curvature which could arise in the local description of matter interactions in small regions of space-time. Transform space rules for evaluating Feynman diagrams in Euclidean anti-de Sitter space are initially defined using eigenfunctions based on generalized plane waves. It is shown that, for a general curved space, the rules associated with the vertex are dependent on the type of interaction being considered. A condition for eliminating this dependence is given. It is demonstrated that the vacuum and propagator in conformally flat coordinates in anti-de Sitter space are equivalent to those analytically continued from $H^4$ and that transform space rules based on these coordinates can be used more readily. A proof of the analogue of Goldstone's theorem in anti-de Sitter space is given, using a generalized plane wave representation of the commutator of the current and the scalar field. It is shown that the introduction of curvature in the space-time shifts the momentum by an amount which is determined by the Riemann tensor to first order, and it follows that there is a shift in both the momentum and mass scale in anti-de Sitter space.


Objective: Few cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been reported in children compared with the total number of cases in the general population. No pediatric studies (or cases) have evaluated extracorporeal techniques in severe coronavirus disease 2019 (COVID-19) patients. In this article, we aimed to describe the clinical features, treatments, and outcomes of four children with COVID‐19 who were treated with therapeutic plasma exchange (TPE) and continuous renal replacement therapy (CRRT) in our pediatric intensive care unit (PICU). Materials and Methods: The children with COVID 19 pneumonia admitted to the PICUs from March 23, and May 6, 2020 were collected. Demographic data and reason for hospitalization were recorded. Vital and laboratory findings were examined in children with extracorporeal treatments. Results: Noninvasive mechanical ventilation, antiviral and antibacterial therapy, supportive antioxidant treatments were administered for 11 children. Respiratory failure and vital signs were more serious in four patients than in other patients. Therefore, we performed extracorporeal support treatments, TPE and CRRT. The patients showed a rapid clinical response to these treatments. Conclusion: TPE and CRRT can use for severe COVID-19 infection receiving other supportive and medical treatments in children.


V.A.Induchoodan Menon, 9, Readers' Row Houses, Gujarat University Campus, Navrangpura, Ahmedabad-380009, Gujarat, India. e-mail: email@example.com Abstract De Broglie when he introduced the concept of the phase wave to represent a particle, assumed that in the rest frame of reference the particle will have the form of a standing vibration. According to the author, this was a serious mistake. He shows that instead, had de Broglie assumed a standing luminal wave structure for the particle, it would have led him to very exciting insights. The author shows that in a relativistic transformation the average energy and the momentum of the forward and the reverse waves forming the standing wave transform exactly like the energy and momentum of a particle. Besides, the plane wave expansion which is used to represent a particle in quantum mechanics is found to emerge directly from this standing wave structure. He proposes to extend the approach to incorporate the spin of the particle and also provide a simple explanation for the Pauli's exclusion principle.


Aerodynamics of short axisymmetric bodies is of importance for the rotorcraft design and operation, where many parts have such shapes or can be represented as a group of such bodies. Of interest for the current study is the drag contribution from a combined shape of the assembly of a proprotor (excluding blades) and a nacelle, the proprotor is attached to. Such an assembly is a common feature in existing tiltrotors and also in many proposed designs of future air taxis. However, experimental and numerical data are scarce in this research area. Our paper presents results of an experimental study, in which we sought to understand whether a bio-inspired shape of the proprotor-nacelle assembly could be beneficial for the drag reduction. Following our previous works on bio-inspired rotor blade designs, the tested bio-inspired proprotor-nacelle assembly design was based on the Cicada body shape. For comparison, experiments were also conducted with other three bodies of the same cross section: short circular cylinder, double bullet, and an ellipsoid based on the V-22 Osprey assembly adopted from NASA publications. In the experiments, all designs were axially oriented with the flow direction at a zero-degree angle of attack, corresponding to the forward horizontal flight. The Reynolds number range was up to 40,000, with incoming flow being laminarized. The drag measurements and flow visualizations were conducted in the water tunnel at the Department of Mechanical Engineering, University of New Mexico.


In the process of intuitionistic fuzzy multiple attribute group decision making,the group decision making matrix is firstly created by combining with decision matrices of experts using intuitionistic fuzzy weighted average operator(IFWA).As to solving the problem of consensus of decision matrices of experts,a adaptive iterative algorithm is created to repeatedly modify decision matrix of experts.The algorithm is capable of attaining consensus between regenerate group matrix and individual decision matrix without manual amending the individual decision matrix by expert,which promotes the efficiency of decision making.The practical example validates the feasibility and practicability of algorithm.


This article explores the role of the religious habit in the lives of Catholic sisters in Poland. It is based on research data from qualitative interviews carried out by the author in five Polish convents. The argument focuses on the indeterminacy of the message which the habit sends to the lay audience. It considers the significance of the habit through a Durkheimian lens. The nuns' accounts of their encounters with the lay public are used to illuminate the precarious position of the Catholic Church in twenty-first century Poland. The article concludes that the habit acts as a 'barometer' for attitudes towards institutionalised religion in Polish society.

The mathematic model of suspension system was established.For there are many rubber components in suspension system,its stress-strain curve is of unsmoothed and strongly nonlinear properties,and the restoring force is of hysteretic characteristics related to distortion history.In order to establish its mathematical model,the restoring force was separated into two parts:elastic part and damping part,and different functions were used to simulate them.The force-to- displacement hysteretic loop was reconstructed using obtained model,which fits in with the experimental data.Then,in accordance with the theories of system dynamics and random vibration,4 DOFs nonlinear dynamic equation of the whole car under road random excitation and considering hysteretic nonlinear properties of suspension,was set up.Monto Carlo method was employed to simulate road exciting spectrum,and the kinematic differential equation of whole car system was simulated in time domain.The result of simulation was also compared with that of the corresponding linear system.The in- fluences of nonlinear suspension property on automobile ride comfort were illustrated.


In preparation for optical/IR interferometric searches for substellar companions of nearby stars, we undertook to characterize the fields of all nearby stars visible from the Northern Hemisphere to determine suitable companions for interferometric phase referencing. Because the Keck Interferometer in particular will be able to phase-reference on companions within the isoplanatic patch (30″) to about 17th magnitude at K, we took images at V, r, and i that were deep enough to determine if field stars were present to this magnitude around nearby stars using a spot-coated CCD. We report on 733 fields containing 10,629 measurements in up to three filters (Gunn i, r and Johnson V) of nearby stars down to about 13th magnitude at V.


ABSTRACT Aim: The aim of this study was to evaluate the hydrogen peroxide and cetylpyridinium chloride as bacterial decontaminants of dental unit water lines at a private Peruvian dental school. Materials and Methods: Water samples were obtained from 66 dental units of a University Dental Clinic before decontamination treatment and at days 3 and 7 thereafter. The biofilm treatments were applied equitably among the two treatment groups (n = 22) and one negative control (distilled water). The samples obtained on each collection day were taken to the biochemical laboratory in thermal boxes and then diluted, seeded, and incubated at 37°C for 24h to count colony forming units per milliliter (CFU/mL). Results: The samples to which hydrogen peroxide were applied had a mean of 1.53 × 105 CFU/mL before application, 0.04 × 105 CFU/mL at day 3, and 0.03 × 105 CFU/mL at day 7, whereas the samples undergoing cetylpyridinium chloride treatment had a mean of 1.74 × 105 CFU/mL before application, 615.38 CFU/mL on day 3, and 307.69 CFU/mL on day 7. Distilled water treatment showed a mean of 1.72 × 105 ± 0.39 × 105 CFU/mL at baseline, 1.51 × 105 ± 1.40 × 105 CFU/mL at day 3, and a mean of 1.74 × 105 ± 0.47 × 105 CFU/mL at day 7. Statistically significant differences were found among the three treatment groups at days 3 (P ≤ 0.001) and 7 (P ≤ 0.001) but not at baseline (P = 0.306). Conclusions: The antibacterial effect of cetylpyridinium chloride was significantly greater than that of hydrogen peroxide and distilled water, and can, therefore, be used for bacterial control in the water lines of dental units.
