Optimized geometrics, energies, vibrational frequencies and normal mode displacement vectors using ab initio SCF calculations at the STO-3G and 3-21G level of theory are reported for two clusters based on the diamond lattice, isotetramantane, C[sub 22]H[sub 28], and methylisotetramantane, C[sub 23]H[sub 30]. Additionally, molecular mechanics on larger diamond clusters, [approx]C[sub 140], are also reported. The calculated vibrational spectra, together with the normal mode displacement vectors, are used to assign infrared-visible sum-frequency generation spectra of hydrogen-truncated diamond -(1 x 1) and methyl-truncated diamond -(1 x 1). 29 refs., 9 figs., 4 tabs.


ABSTRACT The structure of contingent query sequences within adult–child discourse was examined. The children, aged 1; 11–3; 0 in language stages I–III, demonstrated basic knowledge of the contingent query. Implications for conceptualizations of the young child's communicative competence and for theoretical formulations of the query sequence itself are discussed.


Here we offer a newer and more concise proof of Desargues Theorem in projective geometry by means of perspective correspondence.


SUMMARY INTRODUCTION. Cerebral palsy still is a frequent disorder in children. Multiple therapeutic approaches have been used without major success. OBJECTIVES. To determine the anti-spastic effect of excitatory Trans- spinal cord magnetic stimulation in two pediatric patients with cerebral palsy. MATERIAL AND METHODS. The patients received excitatory trans spinal cord magnetic stimulation (cervical and dorsal) one session per week during four weeks. Physical therapist made a blind evaluation of spasticity and motor function, before, during and after treatment. RESULTS. It was evidenced physiological transitory anti-spastic effect and motor function improvement in both patients without side effects. CONCLUSIONS. The excitatory trans- spinal cord magnetic stimulation is a novel, safe and non invasive therapeutic approach for patients with cerebral palsy (Acta Neurol Colomb 2006;22:25-29).


We show that Koszul duality for operads in $(\mathrm{Top},\times)$ can be expressed via generalized Thom complexes. As an application, we prove the Koszul self duality of the little disk modules $E_M$. We discuss implications for factorization homology, embedding calculus, and confirm an old conjecture of Ching on the relation of Goodwillie calculus to manifold calculus.


The 600-plus pogroms following the Manifesto of October 17, 1905, could have been prevented or interdicted by timely actions on the part of the police and army. Instead, soldiers and policemen are widely seen to have favored the pogrom's perpetrators, and their commanders have been seen as complicit in that behavior. Older pogrom narratives viewed this as a centrally planned conspiracy to drown the revolution in Jewish blood. Contemporary narratives have transferred this explanation to the local level, merging rank-and-file and command-level motives and relying heavily on anti-Jewish animus and ideology to explain the pogroms. A close examination of the mid-October actions of the civil and military authorities in two key southern Russian cities reveals structural and conjunctural complexities underlying the apparent parallels between official and crowd behavior.


The primary focus of this paper is on efficiency wages and their testable implications. In particular the nature of the relationship between efficiency wages, productivity and the make up of the labour force is analysed, modelled and subjected to an empirical test. This theory is consistent with the views of many managers and personal administrators, who tend to ascribe primary importance in wage setting to indirect control of the firm's workforce. Here we test a labour augmenting production function where effort depends not only on wages but also on the proportion of temporary workers.


Parents-Children Communication [PCC] remained an area of urgency to be addressed
because the education of children revolves around the communication which was taken as
granted by most of the parents. The research study was carried out across the Southern
Punjab [SP]. The researcher selected the area due to low literacy rate and less socio-economic
status. This research investigated the relationship between PCC and children's Interest in
Education [IIE]. The Emotional Security Theory [EST] and Social Learning Theory [SLT]
were applied to the study. All 6th grade children from SP were considered as population of the
study. The researcher used multistage sampling technique. The survey data was taken from a
balanced sample of 1000 male and female children and analyzed through SPSS version-25.
The study revealed that friendly PCC was positively associated with children's IIE. The study
would be beneficial for the parents to redress their communication with children to build
children's interest in gaining education.


An all-optical clock recovery scheme with wide range of ~12GHz is proposed and demonstrated using a silicon microring resonator assisted by an amplitude equalizer. Single and dual channel clock recovery at 40Gb/s has been achieved.


Material properties of structural steel alloy are variable. Variability may be observed in engineering parameters such as yield stress, modulus of elasticity and strain hardening modulus of the structural steel. Such variability may affect the seismic response of the steel structures. This research study focuses on use of scientific workflows using the Pegasus workflow system, which is available on the NEEShub (nees.org) as an OpenSees Laboratory tool (nees.org/resources/openseeslab) and can provide access to supercomputing resources through the Open Science Grid (OSG), to investigate the possible effects of steel engineering material properties on the simulated seismic response of a steel special moment resisting frame (SMRF). The Pegasus workflow system is used to develop a four-story four-bay steel SMRF model to run on OpenSees (opensees.berkeley.edu). The Pegasus workflow accepts separate coefficients of variation for steel yield stress, modulus of elasticity and ratio of modulus of strain hardening to modulus of elasticity of steel. The workflow then generates different material properties randomly within the defined ranges of the variability. These random material properties are then assigned to the girder and column elements of a series of steel SMRF OpenSees models. The response of these steel SMRFs to various earthquake ground motions are simulated using the OpenSees simulation platform. The output of the simulations are compared in terms of maximum roof displacement, the maximum story drift anywhere in the structure, the maximum roof acceleration response, and the maximum base shear demand. Individual and combined material engineering property variations are compared with results obtained from the reference structure that has no variation in its material properties and for which mean values the material properties are used. It is observed that variability in modulus of elasticity of steel, variability in combinations of modulus of elasticity and yield stress, and variability in yield stress respectively resulted in the highest variations in roof drift, story drift and base shear while variability in the modulus of strain hardening had minimal effect.


‐Schönlein purpura 509 InTROduCTIOn Henoch‐Schönlein purpu‐ ra (HSP) is a systemic vasculitis with deposi‐ tion of immunoglobulin A (IgA) immune com‐ plexes and neutrophil and eosinophilic infiltra‐ tion.1 Inflammation mainly affects small vessels in the skin, joints, kidneys, and gastro intestinal tract (TABLE 1).2 The etiology of HSP is unknown. Viral and bacterial infections, malignancies, vac‐ cinations, some drugs, hypersensitivity to cer‐ tain allergens, and cryoglobulinemia are be‐ lieved to be potential risk factors. Genetic fac‐ tors are also involved to some extent in the eti‐ ology of the disease (renin ‐angiotensin system gene polymorphisms, the presence of HLA‐B35). However, the assessment of this genetic back‐ ground in terms of predisposition to HSP and severity of the disease is varied.3 HSP is a predominant presentation of system‐ ic vasculitis in children, and its prevalence peaks in 4–5‐year‐old children.1 The course of the dis‐ ease is usually mild, with full recovery within several weeks or months.2 The disease recurs in about 40% of cases.1 Although 20‐fold less common4, HSP is associated with more severe manifestations and prognosis in adults than in children5. The typical first symptoms, both in adults and children, are skin lesions including purpura, hemorrhagic vesicles, necrotic ulcers1, mainly on the lower extremities and buttocks2. Skin necrosis rarely occurs in children (<5% of cas‐ es) and the probability of necrotic lesions increas‐ es with age.5 The incidence of abdominal pain, nausea, vomiting, and joint symptoms is similar in children and adults. Diarrhea, gastrointestinal bleeding and renal involvement are significant‐ ly more prevalent in adults.6 It has been demon‐ strated that the risk of chronic renal insufficien‐ cy is also higher in adults.5 Based on a long‐term follow‐up of adults with HSP, it has been demon‐ strated that the risk of chronic renal insufficien‐ cy is increased by the following factors: presence of glomerular crescents, macrophage infiltration and tubulointerstitial lesions2, early‐onset renal failure, hypertension at presentation and during follow‐up, proteinuria (>1 g/d) during follow‐up, age <30 years and male sex4. Several investiga‐ tors showed that the occurrence of proteinuria >1 g/d at the onset of disease is also an indepen‐ dent risk factor of chronic renal failure.4 In rare cases, HSP may coexist with monoclo‐ nal gammopathy (e.g. multiple myeloma)7 or even precede its onset a few years8.


The effect of environment on galaxy formation poses one of the best constraints on the interplay between mass assembly and star formation in galaxies. We present here a detailed study of the stellar populations of a volume-limited sample of early-type galaxies from the Sloan Digital Sky Survey, across a range of environments ‐ defined as the mass of the hos t dark matter halo, according to the groups catalogue of Yang et al. The stellar populations are explored through the SDSS spectra, via projection onto a set of two spectral vectors determined from Principal Component Analysis. This method has been found to highlight differences not seen when using standard, model-dependent comparisons of photo-spectroscopic data. We find the velocity dispersion of the galaxy to be the main driver behind the different star formation histories of early-type galaxies. However, environmental effects are seen to play a role (although minor). Our Principal Components allow us to distinguish between the effects of environment as a change in average age (mapping the time lapse of assembly) or the presence of recent star formation (reflecting environment-related interactions) . Galaxies populating the lowest mass halos have stellar populations on average �1 Gyr younger than the rest of the sample. The fraction of galaxies with small amounts of recent star formation is also seen to be truncated when occupying halos more massive than MH >


An identification scheme is a very important and useful cryptographic tool.This paper introduces two efficient and provably secure ID-based identification schemes which are derived from efficient Boneh-Boyen signature scheme,which is provably secure in the standard model based on the strong Diffie-Hellman assumption.In the standard model this paper also shows that one scheme is secure against impersonation under passive attack and the other scheme is secure against impersonation under active and concurrent attacks.


The proposed Vehicle Information Inspection System (VIIS) includes inspection of the vehicle color, type, and license plate. The aim of this paper is to recognize the moving vehicle's color, type, and license plate characters. The vehicle color is recognized using K-means clustering method and K-Nearest Neighbors (K-NN) method. The vehicle type is recognized using Convolutional Neural Network (CNN). The proposed vehicle license plate recognition system consists of four processes: license plate localization, license plate skew correction, character segmentation, and character recognition. CNN is also mainly used to recognize license plate characters. The extracted vehicle information is stored in the database. This information is matched and inspected with the blacklist vehicle information in the database. The proposed method can help in monitoring and inspection of the blacklist vehicles on the road without any human effort.

Radiofrequency (RF) ablation is an established practice for the treatment of pediatric osteoid osteoma, and for the ablation of the accessory conduction pathways that cause cardiac arrhythmia in children. The RF tumor ablation literature is mushrooming with studies that apply to adults, but it is non-existent in pediatric oncology. However, a percutaneously placed radiofrequency probe can ablate the primary and metastatic tumors of the liver, lung, bone, soft tissue, kidney, and other structures in children. This is an alternative treatment for the local control of tumors that may not be amenable to surgery, chemotherapy, or radiotherapy. RF ablation has advantages over surgery by potentially causing less tissue loss. This is especially true for lesions that are deeply seated. Chemotherapy is limited by regional vascular access and high interstitial pressures in the tumor, which can make diffusion of the chemotherapy to parts of the mass difficult or impossible. Radiotherapy is impacted by the oxygenation of the tumor; areas of the tumor that are hypoxic do not respond as favorably to radiotherapy. RF ablation and other thermal ablation techniques can overcome the problems of these other local control techniques and potentially can completely ablate the tumor.


The most effective dose of mitomycin C (MMC) in the treatment of primary acquired melanosis (PAM) with atypia of the conjunctiva and cornea has yet to be established. This case report describes successful treatment of PAM with atypia with a single four day cycle of 0.02% MMC.


Due to the limited resources of home-based elderly care monitoring equipment, how to accurately identify the elderly behavior is a hot issue concerned by many equipment manufacturers. A behavior recognition method suitable for embedded equipment is proposed. This method first introduces the TPN module in the SlowFast network to capture the visual action tempo of the elderly and uses Faster-CNN to detect the elderly and objects in the video frames. Then in the AIA module, the accuracy of the elderly indoor behavior recognition is improved by strengthening the correlation between the elderly and the objects. Experiments show that the improved network can run stably at 18FPS on Jetson Xavier NX. The indoor behavior recognition accuracy for the elderly reaches 90.61%, which is 8.25% higher than the original SlowFast network.


Aimed at the large difficulty of gap adjustment in alkaline peroxide mechanical pulp(APMP) refiner,a human-simulated intelligent PID controller for APMP refiner was proposed based on the advantages of the human-simulated intelligent and PID algorithm.The simulation results and practical application show that this method is feasible and accurate.

Abstract High grade gliomas (HGGs) are aggressive, primary brain tumors with poor clinical outcomes. To better understand glioma pathobiology and find potential therapeutic susceptibilities, we designed a custom-panel 664 cancer- and epigenetics-related genes and employed targeted next generation sequencing to study the genomic landscape of somatic and germline variants in 182 glioma samples of different malignancy grades. Besides known alterations in TP53, IDH1, ATRX, EGFR genes, we found several novel variants that can be potential drivers in gliomas. In four patients from the Polish glioma cohort, we identified a novel recurrent mutation in the TOP2A gene coding for Topoisomerase 2A in glioblastomas (GBM, WHO grade IV gliomas). The mutation results in a substitution of glutamic acid (E) 948 to glutamine (Q) of TOP2 A and we predicted this E948Q substitution may affect DNA binding and a TOP2A enzymatic activity. Topoisomerases are enzymes that control the higher order DNA structure by introducing transient breaks and rejoining DNA strands. Using recombinant proteins we demonstrated stronger DNA binding and DNA supercoil relaxation activities of the variant proteins. Glioblastoma (GBM) patients with the mutated TOP2A had shorter overall survival than wild type TOP2A GBM patients. Computational analyses of transcriptomic data showed that the GBM samples with the mutated TOP2A have different transcriptomic patterns suggesting higher transcriptomic activity. The results suggest that TOP2A E948Q variant strongly binds to DNA and is more active in comparison to the wild-type protein. Altogether, our findings suggest that the E948Q substitution leads to gain of function by TOP2A.


rarely get more than very temporary relief, which the authors feel is seldom worth the effort made by the patient or the radiotherapy department. Radical x-ray treatment, which is an attempt to destroy the tumour, was given to 129 patients. Almost all of these were regarded as having inoperable growths, but in many cases the treatment prolonged life: 30 patients were alive at the time of the survey-that is, after at least a year from treatment -and of those who had died the average period of survival was 10 months. At the present time it cannot be doubted that relief of symptoms is the best that can be offered to most sufferers from this increasing and predominantly male disease. As Brooks and his colleagues claim, x-ray therapy offers the only means of symptomatic relief in the majority of patients.


Abstract : This document presents the results of a pilot study performed for the Air Force Aerospace Medical Research Laboratory to determine the feasibility of simulating Pasquill Stability Index, wind speed, cloud cover, and wind direction for a diffusion model. The author concluded that the wind speed and direction should be modeled together, but that cloud cover should be modeled separately because of the low correlation between cloud cover/wind speed and cloud cover/wind direction. Wind speed and cloud cover, according to the author, can be used to simulate a Pasquill Stability Index. Keywords: Meteorology; Climatology; and Frequency distributions.


In previous work, the phase stability of Fe-Cr-Mn alloys during irradiation was investigated in a study that included simple binaries, simple ternaries and commercially produced alloys. These low activation alloys are being considered for fusion reactor service in the first wall and in other structural applications subject to high neutron doses. In addition to phase instabilities observed within the grains, grain boundaries were susceptible to varying levels of precipitation dependent upon alloy composition, displacement dose and irradiation temperature. This paper describes the grain boundary microstructures that developed in these Fe-Cr-Mn alloys during irradiation.


Mountainous regions are often affected by food shortages due to the adverse natural environmental conditions, inconvenient transportation and social marginalization, and the food security in these areas has become the focus of the academic community. Guyuan Prefecture is an environmentally fragile, mountainous region in western China. Although food production has increased steadily over the past four decades, 21.4% of the households in Guyuan Prefecture still suffered food shortages in 2008, the food insecurity has become more severe in this region in recent years. The goal of this study is to identify the key factors affecting food security between 1981 and 2005 and to provide some recommendations for improving food security. The panel model was used to analyze the significance and intensity of the primary factors influencing food production in this study. We identified the status of food security by examining the grain production per capita. Our results show that poor environmental conditions and population pressure are the major factors influencing food production in Guyuan. Food security might be improved if more fund and technology were invested in the fields of transportation and irrigation. Besides, climate change has a positive impact on food production, the increase in temperature tends to alleviate food insecurity. In addition, infrastructure construction in the agricultural sector should be strengthened and the population growth should be controlled in Guyuan Prefecture.


Summary

The effect of commerical olive oil refining processes on the total polyphenol and 1,2-diphenol content of the oil was investigated. the mean losses of total polyphenols and 1,2-diphenols of the crude oils were 84-87% and 79-88% respectively. There was no difference between the chemical and physical refining processes in reducing phenols in the oil samples.


Energy consumption for rail transport represents at most half of that used on road transport. This is due to the low level of resistance of steel wheels running on rails compared to rubber wheels on a road surface. In air traffic energy consumption over a distance of 1500 km when working at full capacity is equal to the value of one private car. For short distance traffic petrol consumption for a private car is 10 times higher than that of public transport. Energy consumption for river transport is roughly equal to railways whereas on canals, for example in the transport of coal, it is four and a half times higher than for rail transport by electric traction.


Significance The frequency discrimination important for animal communication and survival is achieved via a special functional arrangement of cells along the length of the cochlea. Hair cells at the base are tuned to high-frequency sounds, whereas those at the apex are tuned to lower frequencies. Gradual anatomical and physiological changes along the cochlea facilitate this frequency selectivity, but it remains unclear how this functional arrangement is established. Using mouse genetics, we found SHH specifies apical identity in the cochlear primordium. Then, SHH and FST together maintain cochlear cells with an apical fate. In the absence of FST or SHH, mice produce short cochleae lacking the apical domain, leading to low-frequency hearing loss.


Objective: To investigate the enriching blood effect of Aleppo avens.Methods: Blood loss was used to establish an acute hemopenia mouse model.Hemoglobin(Hb) and red blood cells(RBC) were measured on the 9th day administration after treatment with different concentration of Aleppo avens respectively.Results: Compared with the beginning of administration,the levels of Hb and RBC in every groups of Aleppo avens have a significant increased(P0.01),compared with the model group,the two levels in every groups of Aleppo avens have a significant increased(P0.01).While compared with the angelicae-radix group,the two levels have a decreased(P0.05 or P0.01).Conclusion: Aleppo avens has an enriching blood function.


The Cup of jamshid is one of the symbolic objects in the mystical culture and ancient myths of Iran that is ontologically encoded into the world of creation. This cup holds the power and the ability to represent the events and truths of the universe from eternity to show what is there, such as clear rituals to the conscious mysteries of this world. The breadth and depth of the Cup of jamshid is in such a way that despite its interpretations, it is still in a state of ambiguity. HafIz is known as one of the poets who has benefited most from the Jam-e Jam. He considers the benefit of this cup as a godly attitude to the universe. This attitude leads people out of illusions and into the cosmos of the unseen and the vision. Because the value of a person's life and credit depends on his or her vision and the attitude of the person that determines his or her behavior. Thus, human behavior will not be directed until the human angle is corrected. In this study, the symbolism of the Cup of jamshid is discussed first, then the origin of the Cup of jamshid is then explored in Persian literature and Islamic mysticism. Finally, while looking at the emergence of the Cup of jamshid in literary and mystical works, we will discuss its mysterious role in the Hafiz ontology system and its educational function in human life here and now.


Soil moisture is one of the important factors affecting the growth of crops. Accurate monitoring and forecasting of soil moisture in the growth period of crops is an important part of agricultural production. In this study, 15 predictors from three aspects of meteorology, topography and soil properties in Baoji were selected to establish the machine learning model to predict the soil moisture in 0~20cm and 20~40cm soil layers. The prediction of same data was carried out by three models, which were support vector machine (SVM), random forest (RF) and back-propagation neural network (BPNN). The results showed that the prediction accuracy of SVM were 92.899% and 92.656% in 0~20cm and 20~40cm soil layers, the RMSE were 7.521 and 8.011 respectively, while the RF were 87.632% and 87.842% in prediction accuracy, 10.759 and 11.042 in RMSE, and the prediction accuracy of BPNN were 80.570% and 85.323%, the RMSE were 12.147 and 11.165. The study found that the three models have good prediction effect on winter wheat soil moisture in Baoji, reflecting the good application ability of machine learning model in soil moisture prediction. And the prediction accuracy of three models in 0~20cm soil layer were slightly better than that in 20~40cm. Compared with the model of RF and BP, SVM has better prediction results. And the analysis of predictors showed that the meteorology has greatest impact on soil moisture and its changes, which the precipitation, air relative humidity and sunshine duration most; the effects of topography is relative, which the slope and elevation have great influence; soil property has little effect on the change of soil moisture, which the thickness of plough layers has slightly stronger influence than other factors.


With the advancement of rural urbanization and villager urbanization,many scholars began to pay attention to the atrophy of public space in rural community as well as arising from the lack of participation and lack of identification.These problems showed different characteristics in the Y village in Jiangsu and L village G village in Guizhou.Influenced by public space and associating benefits,the degree of community participation in Y Village is much higher than in L village and G village.Whether in Jiangsu or in Guizhou,the degree of villagers′ volunteerism participation and the private network participation as well as public affairs participation are in descending order,but L Villagers and G villagers is amplitude.At the same time,the emotion and behavior recognition of Y villagers in Jiangsu is higher than L villagers G villagers in Guizhou significantly. The multiple linear regression in different regions found that participation did not necessarily promote identity.In closed and strong homogeneity village in Guizhou,community participation has remarkable positive effect on community identity;And in the open and strong heterogeneity village in Jiangsu,the community participation has very weak influence on community identity.What′s more,this influence is disequilibrium.Binary Logistic regression found that villagers′ background variables such as nation、income level influence on community identity significantly.These findings have great help to improve the villagers′ community identity.


Abstract : The coupling between electronic excitations and optical modes have been of considerable interest in studies of atoms in optical cavities and optical excitations in semiconductor microcavities. The electromagnetic spectra of atoms in optical cavities exhibit splittings due to the coupling of the atomic dipole transitions with the radiation field. These coupled modes are called the vacuum field Rabi oscillations and the splittings between them are the vacuum field Rabi splittings. In case of electronic excitations in semiconductor microcavities the optical modes are coupled to excitons and the exciton photon modes are often called cavity polaritons. These couplings are important for understanding such effects as optical bistability and laser action.


A knowledge of the intimate relationships between the transverse colon, transverse mesocolon and duodenum is often of critical importance in the roentgen analysis of upper abdominal pathology. Detailed study of their anatomic relationships was made by sections derived from frozen cadavers.These observations are essential in the roentgenologic interpretation of a variety of disease states including defect of the mesocolon with internal herniation into the lesser sac, masses developing within the mesocolic leaves, secondary effects on the descending duodenum from carcinoma of the hepatic flexure, extension of neoplasms of the duodenum to involve the colon, acute pancreatitis, abdominal aneurysm, and distinction of an abscess of Morison's pouch from an inframesocolic abscess.Diagnosis of spread from colonic carcinoma by the effect of lymph node metastases upon the duodenojejunal junction is shown.


A microwave part-shaped applicator was designed to be competitive with conventional liquid composite molding processes. Three glass-reinforced diglycidyl ether of bisphenol A epoxy composites with a diaminodiphenyl sulfone curative are processed in the part-shaped cavity by microwave heating, conventional heating, and hybrid heating where both microwave and conduction heating are employed. Hybrid heating provided superior heating uniformity due to complementary heat transfer mechanisms: an outward flux of thermal energy from microwave heating combined with an inward flux of energy associated with conventional heating. Because of the penetrating nature of microwave energy, the time required to attain the cure temperature in the composite center was reduced by more than 85% using microwave and hybrid heating methods.


I wish to present a perspective from American culture and history, which may help to explain dominant American tendencies to resort to the unilateral use of force to resolve what they take to be demands of their national security. This is very far from wishing to deny the importance of international law either as an intellectual construct or as an ideological weapon. Indeed the wider cultural, historical analysis is intended to demonstrate the contrary. International law language is the final battleground in the struggle for legitimacy, which always accompanies the use of force. Nonetheless, international law is plagued by the problem of auto-determination of its normative system, by the absence of a framework of compulsory adjudication of disputes. This fact ought to lead international law theorists to attach exemplary importance to the character of international legal personality. If indeed it is a feature of the legal personality of states that they have sovereignty, why is it that international lawyers treat this fact as purely formal. Does state independence from authoritative external criticism not have itself a substantive aspect, a cultural, symbolic dimension that the history of the discipline can more fully elucidate?

A series of poly(methylene acetals) were prepared from 1,5-pentanediol by systematically varying the aldehyde. The viscosity of each polymer was measured, and, for the first four members of the series, shown to vary inversely with the length of the pendant chain of the aldehyde. A comparison of the viscosity of a polyether (a polyoxypropylene glycol) in which the ratio of carbon to oxygen in the chain is 2/1 with that of a poly(methylene acetal) in which the carbon to oxygen ratio is 3/1 indicated a significant decrease in viscosity with increasing concentration of ethereal oxygen.


perhaps in an appendix. His call for membership in what he calls the "American family" would provide an interesting parallel to his campaign for inclusion in Gold's domestic circle. In addition to Boudinot's address, Gaul might also have included a discussion of the letters' resemblance to epistolary novels like Hannah Foster's The Coquette. The following words from Harriett's relatives, who regard her engagement as catastrophic, seem drawn from the pages of Foster's bestselling novel: "The dye is cast, Harriet is gone, we have reason to fear" and "They may yet do it; & if [Harriett] must die for an Indian or have him, I do say she had as well die, as become the cause of so much lasting evil as the marriage will occasion" (81, 121–22). Such comparisons would shore up a literary analysis of these letters, helping us think about how a real-life Anglo-Indian romance related to and revised epistolary and sentimental conventions. As outrageous as the GoldBoudinot marriage was thought to be, it had important literary ancestors. The last section of Gaul's book, which includes the letters Harriett and Elias wrote to her relatives after their marriage, is a poignant affirmation of Cherokee nationhood. As Boudinot writes in a later letter to Harriet's sister and brotherin-law, "The last right and in some respects, the most important right of the Cherokees, is to be fought and contended for—their right to the land. It is true we have been abused persecuted and oppressed beyond measure—illegible our rights have been outrageously wrested from us, yet we are on our lands—we have possession" (175). Unlike some studies that claim to acknowledge native sovereignty and yet limit "the nation" in question to the United States, Gaul concludes her introduction with an assertion that these letters render the histories of "two nations" (66). The repetition of the word "nation" in reference to the Cherokees serves as an important reminder of the unique political status of indigenous peoples; despite the removal policies of the nineteenth century and other challenges to native sovereignty, the possession that Boudinot speaks of persists.


Honey is always among the lists for food fraud around the world. A whistleblower surfaced in a South African Honey manufacturer that claims their honey is revealed as passing off a sugar concoction. Also, in the Philippines, mid-2016 there's a manufacturer of honey named Cem's Honey that mislabels their product as real honey but in fact their product is a fake honey. The main objective of this study is to create a system that could classify a honey whether it is genuine or fake using Artificial Neural Network with Gradient Descent Backpropagation as the training algorithm, and sensors (Electrical Conductivity and pH Sensor). Through testing, the system classified the presented samples at an accuracy rate of 87.5%. In conclusion, the researchers successfully developed a system that can classify a honey whether is it genuine or fake using Artificial Neural Network.


The thermal insulation effect of the coating was closely related to the content of the thermal insulation filler, but too much filler would cause interfacial compatibility problems of various substances in the coating, micro-defects in the coating, and affect the anti–corrosion performance of the coating. Therefore, solving the interface problem was the key to preparing a coating with heat insulation and anticorrosion functions. In this study, organic–inorganic hybrid polymer was used to modify the surface of vacuum ceramic microbeads, and epoxy–silicone resin was used as the film–forming material to prepare a heat-insulating and anticorrosive coating that can withstand 200 °C. The SEM morphology showed that the interface compatibility of the vacuum ceramic beads modified by the organic–inorganic hybrid agent and the film-forming material were improved, the dispersibility was significantly improved, and the beads were tightly arranged; the thermal conductivity of the coating reached 0.1587 W/(m·K), which decreased by 50% after adding 20% ceramic beads, ANSYS finite element simulation showed that the coating has good thermal insulation performance; after the coating underwent a thermal aging test at 200 °C for 600 h, the microstructure was dense, and the low-frequency impedance modulus was still around 109 Ω·cm2. There was no obvious defect in the microstructure after the alternating cold and heat test for 600 h; the low-frequency impedance modulus was still above 108 Ω·cm2, and the low-frequency impedance modulus of the coating was 1010 Ω·cm2 after the 130d immersion test, indicating that the coating had good heat resistance and anti-corrosion performance.


In this study a legal and social analysis is done to give account of the current state of the restoration proposed by the 2005 Justice and Peace Law. Restorative law indicates a victim to be restored and for both the victim and victimizer to be psychosocially accompanied, which allows us to get closer to a rights equality equilibrium point for all the citizens as the Constitutional Magna Carta demands. The Constitutional Carta Magna bases its statute on the Humanitarian International Law as a social equilibrium point and a new door to social cognitive restoration.


Reviews methods of estimating shopping centre turnover in the absence of published census information. Discusses use of market area analysis and reviews the experience of surveying retailers themselves in order to measure turnover. Reports a case study of small towns in mid Wales which found that about 70 per cent of the retailers approached were willing to be surveyed, and of these about 70 per cent were willing to provide information on turnover. Examines the use of surrogate measures such as retail employment and concludes that, while such surveys are worthwhile in present circumstances, reinstatement of a centrally organized compulsory census is essential in the longer term.


With the availability of massive general-domain dialogue data, pre-trained dialogue generation appears to be super appealing to transfer knowledge from the general domain to downstream applications. In most existing work, such transferable ability is mainly obtained by fitting a large model with hundreds of millions of parameters on massive data in an exhaustive way, leading to inefficient running and poor interpretability. This paper proposes a novel dialogue generation model with a latent structure that is easily transferable from the general domain to downstream tasks in a lightweight and transparent way. Experiments on two benchmarks validate the effectiveness of the proposed model. Thanks to the transferable latent structure, our model is able to yield better dialogue responses than four strong baselines in terms of both automatic and human evaluations, and our model with about 22% parameters particularly delivers a 5x speedup in running time compared with the strongest baseline. Moreover, the proposed model is explainable by interpreting the discrete latent variables.


The aim of the study is the examination of the relative portal blood flow, by assessment of the hepatic perfusion index (HPI) in different degrees of hemodynamic alterations related to liver cirrhosis and some focal liver diseases. Hepatic radionuclide angiography (HRA) was performed with bolus injection of 740 MBq- 99m-Tc-pertechnetate, during one minute (1 f/sec), using ROTA scintillation camera and Micro Delta computer (Siemens). HPI was estimated using Sarper's method of slope analysis. In 10 controls (C), HPI was 0.68 ± 0.06; it was significantly decreased (p < 0.01) in 5 patients with chronic active hepatitis (HAH, 0.57 ± 0.03), 13 with liver cirrhosis without (LC, X = 0.49 ± 0.13) and 18 with esophageal varices (LCEV, X = 0.32 ± 0.19), as well as in 4 patients with LC and sclerosated esophageal varices (LCSEV, X = 0.16 ± 0.11). Comparing to HAH and LC (HAH-LC, p > 0.05), HPI values were significantly lower in LCEV (p < 0.01) and LCSEV (p < 0.05), while the values between the last two groups didn't differ (p > 0.05). In 22 patients with liver hemangiomas (LH, X = 0.64 ± 0.08) HPI values were physiological (C-LH, p > 0.05). However, in 4 patients with hepatocellu- lar carcinoma (H, X = 0.26 ± 0.20), and 8 with liver metastases (LM, X = 0.40 ± 0.28), HPI values were significantly decreased (p < 0.01), but they didn't differ between themselves (H-LM, p > 0.05). Portal liver perfusion decreases in respect to the portal hypertension and collateral circulation development. Thus, significant difference is proved between HPI values in cirrhotic patients with and without esophageal varices, while after sclerotherapy, HPI remains very low. Considering that in patients with hemangiomas, HPI values are normal, which is not the case in those with primary carcinomas and metastases, HRA is a useful method for the differential diagnosis of hemangiomas and primary liver carcinomas, together with ultrasonography and blood pool scintigraphy. The object of the study is an assessment of the endoscopic aspects of the gastric mucosa in patients with portal hypertension (PHT) and hepatic cirrhoses (HC), together with an estimation of the underlying histological changes leading to these modifications, and also a comparison with the ul-trasonographic, laparoscopic and splenoportographic modifications. Material and Methods: The study was carried out on 60 patients with PHT and HC in different evolutive stages. Eso-gastro-duodenoscopy was per- formed in all patients, and the modifications of the gastric mucosa were de-termined. In some patients antral and fundic biopsies were taken. The endo- scopic aspects were correlated with the Child-Pugh stages of HC and compared with the ultrasonographic, laparoscopic and splenoportographic signs of PHT. Results: Four types of endoscopic gastric mucosa modifications were noted: (1) A scarlatina rash and superficial erythema in 10 cases (16.6%), with no significant histological changes. An inflammatory infiltration of the gastric mucosa was seen in six cases with alcoholic cirrhoses. (2) The mosaic pattern (snake skin), in 15 cases (25%), seen as a fine reticular pattern separating ar- eas of erythematous edematous and normal mucosa, localised mostly in the antrum, but also in the fundic area of the stomach, and even on the duode- num; histologically, there were no significant changes, but electron micro-scopic findings revealed ectasic submucosal capillaries. (3) cherry red spots and diffuse hemorrhagic gastritis in 12 cases (20%). Five of these patients had upper gastrointestinal bleedings. Histology revealed submucosal venous and capillary dilatation and submucosal inflammatory changes in eight cases. (4) Gastric cardial varices (stages' 1-3) in 14 cases (23.3%), often associated with esophageal ones. Three of the patients were bleeding from these varices. Nine of the patients (15%) had normal gastric mucosa, without any modifica-tions.The ultrasonography, laparoscopy and isotopic splenoportography (with 119 In, and the determination of the spleno-porto-cardiac circulation time) confirmed the presence of elements of PHT in all patients with erythema and varices at the gastric level. A good correlation with the evolutive stages of HC has been noted. Conclusions: The presence of a congestive gastropathy in patients with PHT and HC has been demonstrated. The gastric inflammatory infiltrate was present in 28% of the cases, in correlation with the alcoholic etiology of HC. TIPS is a radiological method for treating upper gastrointestinal bleeding in cirrhotic patients. TIPS has been shown to decrease the portosystemic gradient by about 40%. Little is known of the effects of TIPS on portal hemo- dynamics. We examined 15 patients (9 M, 6 F, age range 53-72 yrs) who underwent TIPS for variceal bleeding (13 pts) or intractable ascites (2 pts). A doppler US was performed before and 48 hrs, 7 days, 1, 3 and 6 months after TIPS. The following parameters were measured: maximum (VMax) and aver- age (VMean) velocity of blood flow (cm/sec) in the portal (PV), splenic (SV) superior mesenteric (SMV) veins and stent. Results: Purpose: Transjugular intrahepatic portosystemic shunt (TIPS) is used as a safe and effective method for short term treatment of symptomatic portal hypertension. However, there are significant risks of hepatic encefalopathy and the shunt stenosis. These risks and technical complications were reviewed. Material and Methods: Twenty eight consecutive mostly cirrhotic patients were treated with TIPS for variceal bleeding (78%) and intractable ascites (22%)with follow-up ranging from 1 to 16 months (mean 8 months). Shunt pa- tency was evaluated by doppler sonography. Shunt velocities below 25 cm/s indicated stenosis. Results: Technical success was achieved in 100%. 30-day mortality was 11 %. Early (within 48 hours) thrombosis of the shunt occurred in 3 patients (11 %). All these shunts were recanalised. Significant stenosis of the shunt was found in 3 (11 %) shunts and shunt occlusion occurred in 1 patient within 3 to 14 months after TIPS. The stenotic shunts responded well to angioplasty and parallel shunt was performed in the patient with shunt occlusion. Progression of hepatic encefalopathy occurred in 4 patients (15%). The thrombus formation in portal vein during the procedure was observed in 2 cases and was aspirated or lysed by local streptokinase infusion. The me- diastinal hematoma caused by the brachiocephalic vein injury occurred in 1 patient. Conclusion: (1) Early shunt thrombosis or chronic shunt stenosis are amenable to recanalisation or balloon dilatation. (2) Doppler ultrasonography is accurate in noninvasively assessing shunt stenosis following TIPS. 3) At this time, TIPS placement without careful follow-up cannot be considered as a long term treatment for symptomatic portal hypertension. try) and nutritional status (AC) were evaluated in 15 healthy subjects - control group - (7 girls and 8 boys; age 13.33 y. ± 1.95; mean ± s.d.) and 20 patients (10 girls and 10 boys) with portal hypertension (9 with portal vein occlusion, age 12.56 y. ± 3.40; 11 with liver cirrhosis, age 14.00 y. ± 3.26) and history of variceal bleeding. Under nutrition was diagnosed in 3 controls and in 12 patients (p < 0.05). REE (per kg b.m.) in controls and patients were: 121.87 ± 21.50 kJ and 142.50 ± 32.91 kJ respectively (p < 0.043); REE (per 1.73 m2) were: 6643.87 kJ and 7456.00 kJ resp. (p < 0.0023). Substrate utilisation rate for controls and patients were: glycogen: 1.90 g/kg b.m. and 2.23 g/kg b.m. resp. (n.s.); fat: 1.55 and 2.01 g/kg b.m. resp. (p < 0.04); protein: 1.51 g/kg b.m. and 1.23 g/kg b.m. resp. (n.s.). Conclusions: Patients with portal hy- pertension and history of variceal bleeding are prone to be malnourished as revealed by AC. Increased REE with increased fat utilisation rate can explain that finding. Aims: To compare the efficacy and complications between sclerotherapy and ligation in management of bleeding esophageal varices. Methods: 120 patients admitted to our Background: Endoscopic variceal ligation (EVL) is a viable substitute for en- doscopic injection sclerotherapy. The complications of EVL have been proven to be fewer than those of sclerotherapy. It is still unknown how EVL may in- fluence on the pressure of portal venous system. Methods: 19 patients (18 males, one female, mean age, 60 ± 9 yrs) with history of esophageal varices bleeding and without ascites were enrolled. All were cirrhotic patients (63% were post-hepatitic). EVL was performed at an interval of 2-3 weeks until varices were obliterated. Measurements of portal pressure: Portal-splenovenogram was performed before EVL and after varices obliteration to assess venographic findings. The pressures of main portal vein (PVP), splenic vein (SVP) and superior mesenteric vein (SMVP) were recorded. Results: 16 patients completed the study. A mean of 4 sessions of EVL within the duration of 2 months was needed. 11 (69%) patients had an elevated pressure and 5 (31 %) patients had a reduced pressure after EVL. Mean portal venous pressure before and after EVL was 26.0 ± 4.4 mmHg and 27.9 ± 6.5 mm Hg, respectively (p < 0.05). Among patients with an elevated pressure change, PVP increased by a mean of 24%, SVP increased 18% and SMVP increased 19%. Among patients with a reduced pressure change, PVP decreased 24%, SVP decreased 26% and SMVP decreased 22%. Three patients had rebleeding, all belonged to those with an increased portal pressure change. Conclusions: 1. EVL induced an increased portal pressure by 24% in 70% patients and reduced portal pressure by 24% in 30% patients. 2. Increased portal pressure induced by EVL may result in the occurrence of rebleeding. Previous studies have shown an increase of portal pressure in cirrhotic pa- tients during postprandial states. This increase is caused by an increase in hepatic blood flow, a phenomenon known as postprandial hyperemia. This study was designed to determine whether pos


for the compositional and theological understanding of the Hebrew Bible. The Pentateuch concludes with the story of Moses' death, but this is not really a satisfying thematic conclusion. The promise of land is not fulfilled; this must await the book of Joshua, where Joshua, depicted as the successor of Moses in Numbers, Deuteronomy, and Joshua, completes the conquest of Canaan that was initiated by Moses' conquest of the Transjordan. This was the main reason that critical scholarship created the Hexateuch,1 which served as the dominant JBL 119/3 (2000) 401–419


PIWIL2 is widely expressed in various tumours and implicated in playing a role in tumourigenesis. For a more thorough study of PIWIL2 functions in tumour cells, we aimed to establish PIWIL2‐specific transcript knock‐down/knockout HepG2 cell lines using transcription activator‐like effector nuclease (TALEN) technology. Furthermore, we proposed to use the cell models to explore PIWIL2 functions in TGF‐β signalling in HepG2 cells. HepG2s are human hepatocellular carcinoma cells.


A theory of mechanical damping based on the model developed by Granato and Lucke was extended to small numbers of pinning points per network length and to stresses high enough to produce complete breakaway. The detailed response of a dislocation array to an applied stress was calculated using computer techniques in the low‐frequency (kilocycle) range and both the viscous and hysteretic damping were computed. The amplitude dependence of the viscous and hysteretic damping was computed as a function of loop‐length distribution, distribution of dislocation orientations, pinning point density, and stress distribution. The computation techniques allowed these calculations to be made without the usual mathematical approximations which are shown to result in a severe limitation on the previous analytic expressions. The results were applied to a discussion of the use of the damping theory to obtain parameters which describe the dislocation array and dislocation behavior. The time dependence of dislocation damping which results from diffusion of pins along the dislocation and in the lattice is discussed.


A device which can be used in dentistry operates with two different screwing functions. The functions can be performed with the aid of at least three different types of screwing tools. With a first screwing function, first and second components are held together, and, with the second screwing function, the held-together components are screwed, for example, into the jaw bone in which one component is to be anchored. The first function operates with a Unigrip function, whose screw head is situated inside the first component. The second function operates with an internal Stargrip function and an external hexagon function on the first component. The screw of the first function, with its associated screw head, can be applied insider the first component via a portion forming the Stargrip function.


The health effects of weight loss in older individuals with diabetes is unclear, perhaps related to intentionality of the weight loss. Look AHEAD (LA) is a randomized trial comparing intensive lifestyle intervention for intentional weight loss with diabetes support and education (control) in 5145 individuals (age 45-76 at baseline) with overweight/obesity and type 2 diabetes. We examined the association of weight change trajectories post-intervention (i.e., yrs 8 to 16; M± SD percent weight change= -3.10% ±10.1), and concurrent risk of mortality by comparing weight gainers (N=226), maintainers (N=1459), modest losers (N=2206), and steep losers (N=415). Both weight loss groups were older, more likely to be in DSE, and lost less weight in yrs 1-8. In Cox proportional hazards regression models, adjusted for sex, race, baseline obesity, age, and treatment, mortality risk among the 4 weight change categories differed significantly (p 10 lb over 2 most recent 6-month assessments intentionally, unintentionally, or through the combination (intentional + unintentional), relative to maintainers (no weight loss>10 lb). Adjusted analyses showed that the HR for mortality was significantly greater in both the unintentional (HR=3.26, 95%CI 2.35,5.01) and the combination (HR=2.63, 95%CI 1.28,5.39), but not different in the intentional weight loss group (HR=1.05, 95%CI 0.61,1.81) relative to maintainers. These data suggest that unintentional weight loss is associated with increased risk of mortality in older individuals with diabetes. Disclosure R.R. Wing: None. J. Clark: None. M.

SUMMARY Introduction: In many tumors (including invasive duc- tal carcinoma of the breast) invasive and metastatic ability depends on angiogenesis; therefore, tumoral vascular den- sity evaluation is considered of interest because of its pos- sible prognostic value. Investigation results are controver- sial depending on the method used. We have compared the different methods recommended in the literature in order to find the most suitable one. Material and methods: We have determined the tumoral vascular density in 189 patients with invasive ductal carcinoma (NOS) of the breast using six different methods in histologic preparations immunohistochemicaly stained with CD31 immunohisto- chemically stained slides. Results: The most sensitive and specific method has been the one using 400x in the best hot spot.


The allegorical poems of Bai Ju-yi inherited the realist poem inditing tradition since the Book of Songs. It gained great achievement in the aspects of ideological content and artistic quality and became the powerful tool to reflect reality and criticize abuse. His poems played an important role in the middle Tang Dynasty.


The concessive relation is said to not be expressible by a central adverbial clause (CAC) but by a peripheral adverbial clause (PAC) or a non-integrated dependent clause (NonIC). This is true in the standard case. The paper argues that this ban on the appearance of the concessive as a CAC stems from the fact that the concessive relation standardly involves a judgement, which is due to a conception of an expected course of events that is associated as an implicature with the concessive relation. However, based on d'Avis (2016), it is shown that if a concessive just stands in opposition to a conditional that is salient in the context, it does not involve a judgement and can appear as a CAC. A judgement constitutes a private act of evaluation (Krifka to appear). It follows that in the standard case concessive clauses necessarily involve a richer semantic structure than just a core proposition. This has consequences for syntax. Following Krifka, the paper assumes that the private act of a judgement is syntactically represented in clausal structure by a J(udge)P(hrase). CACs do not contain a JP-projection, but PACs do. NonICs encode a speech act; in addition to a JP they also contain a Com(mitment)P(hrase) and an ActP(hrase). It is demonstrated that while concessives realised as PACs may host so-called weak root phenomena, concessives realised as NonICs may also host commitment modifiers and so-called strong root phenomena. Further distinguishing syntactic properties of concessives realised as PACs or as NonICs are discussed.

To determine nickel in the way of spectrophotometric analysis,synthesis of new triazene group chromogenic reagents became hotspot-researching direction because of high sensitivity and selectivity.In this paper,the synthesis and characteristics of the new chromogenic reagents: 1-(azobenzene)-3-(3-nitro-2-pyridyl)-triazene(ABNPT)were reported.A highly sensitive color reaction of nickel was studied by using ABNPT as chromogenic reagent.The result showed that in the presence of non-ionic surfacetant Triton X-100 and Na_2B_4O_7-NaOH at the range of pH 10.8~11.6,ABNPT formed a stable amaranth complex with Nickel at the molar ratio of 1:3.The maximum absorption wavelength of the complex is at 535nm.The new heterocyclic triazene reagents had higher sensitivity and selectivity than others.It could be applied in determining nickel of core sample with satisfactory results,which had better application background and social benefit.


This paper mainly analyzes how the relative adequacy and intensity of different institutional factors affect regional comparative advantage and export structure.An empirical analysis is made with cross data of China's different regions and 28 manufacturing industries to test the impact of market factors and organizational factors on RRCA.In conclusion,market factors can positively affect regional export advantage while organizational factors might have negative influences,resulting in various reactions to the input of institutional factors in different regions and industries.There is a relatively significant positive impact of organizational factors on the export advantage in developed regions,while relatively backward areas expect more market factors.


doi: 10.7185/geochemlet.1609 The interplay between the chemical composition and the molecular structure of silicate melts was central to the evolution of the Earth's crust, mantle and core. This interplay also affects geochemical records such as the partitioning of isotopes between minerals, melts and fluids in the Earth's interior. For instance, large 2H/1H fractionations between silicate melts and aqueous fluids have been observed at high temperature and pressure. Such behaviour may be promoted by the occurrence of 2H/1H intramolecular fractionation within the molecular structure of silicate melts. New Raman spectroscopy and 1H and 2H Nuclear Magnetic Resonance (NMR) spectroscopy data reveal the source of such 2H/1H intramolecular isotopic fractionation, showing that 1H and 2H fractionate between the silicate tetrahedral units. Such a process might affect other isotopic systems (e.g., N, C, or S) where the isotopes interact with the melt silicate network.

Stock investments in the time of the COVID-19 pandemic have a considerable risk. This happens because of the increasingly uncontrolled movement of stock prices. The potential for steep charts can occur at any time. Sentiment analysis of increasing daily cases of COVID-19 was analyzed to see how much effect it has on stock price movements. This research will analyze stock prices from coal commodities in Indonesia. Researchers choose to discuss coal commodities because, in April 2021, there was a significant increase and highest in November 2021. Because of the data, researchers want to see the influence of some coal companies using selling price data with moderating variables for estimating the stock price. There are 26 coal companies that are listed on Indonesia Stock Exchange. The analysis will be a check on five companies that have the largest investors. The analysis is also carried out on coal sales price movements. Furthermore, five different coal mining companies were analyzed based on the rate of price changes to new selling prices with variable moderation in Indonesia. Increasing daily cases of COVID-19 being variable moderation. The method used for finding the relationship is a linear regression with a moderating variable. According to the analysis, the increasing daily case of COVID-19 as a moderating variable is enough to affect the relationship between the selling price of coal and the stock price of HRUM.JK and PTBA.JK. In stock price HRUM.JK, there is an increasing adjusted R square from 0.5254 to 0.5451. The same conditions apply to PTBA.JK has increased by 0.4040 to 0.4444.


Improving prediction accuracy is a prominent modeling issue in relation to forest simulations, and ensemble learning is a new effective method for improving the precision of crown profile model simulations in order to overcome the disadvantages of statistical modeling. Background: Ensemble learning (a machine learning paradigm in which multiple learners are trained to achieve better performance) has strong nonlinear problem learning ability and flexibility in terms of analyzing longitudinal data, and it remains rarely explored so far in the field of crown profile modeling forest science. In this study, we explored the application of ensemble learning to the modeling and prediction of crown profiles. Methods: We evaluated the performance of ensemble learning procedures and marginal model in modeling crown profile using the crown profile database from China fir plantations in Fujian, in southern China. Results: The ensemble learning approach for the crown profile model appeared to have better performance and higher efficiency (R2 > 0.9). The crown equation model 18 showed an intermediate performance in its estimation, whereas GBDT (MAE = 0.3250, MSE = 0.2450) appeared to have the best performance and higher efficiency. Conclusions: The ensemble learning method can combine the advantages of multiple learners and has higher model accuracy, robustness and overall induction ability, and is thus an effective technique for crown profile modeling and prediction.


In many jurisdictions, organ allocation is done on the basis of the health status of the patient, either explicitly or implicitly. This presentation presents a Matrix-analytic priority model in which customers self-promote to the higher priority level, to take into account changes in health status over time. In the first variant, all patients arrive as "regular" customers to the queue, but as the health of a patient degrades, their status is promoted to "priority" to reflect the increased urgency of the transplant. Performance measures such as the mean and distribution of the time until transplant are obtained.


Aims: The problem addressed in this paper, was to reduce the number of sieves in order to propose appropriate methodologies for the estimations of abundance, secondary production, community composition and structure of benthic fauna associated to a Zostera marina meadow. Therefore we are aiming to calculate in an efficient way, secondary production of benthic communities in coastal areas associated to a Zostera marina meadow and examine the retention efficiency of different mesh sizes . Study Design: Bimonthly five randomly chosen cores of 15 cm of diameter and 18 cm length (area=176.7 cm≤), were collected. Place and Duration of Study: The samples were taken during one year period from June 2008 to June 2009 in a Zostera marina meadow at Punta Banda estuary, a shallow coastal


The necessity of ultrasonic inspection to detect the cracks in turbine blade is being increased as the forced outage of nuclear power plants have been occurred due to blade failure in turbine components. However, the complex blade root geometry causes the ultrasonic inspection technique not to be established yet and much effort is required to set up a more reliable inspection. In this paper, the ultrasonic inspection technique for flaw detectability, skew angle effect, identification of flaw and geometric signal have been investigated with a test block and discussed the interpretation of ultrasonic signal through the acquisition and analysis of RF waveform. The experimental results show that the proper examination procedure can be established. It is required that the skew angle is essential to decrease the effect of signals from the complex blade geometry. The present results of this study can be applied to the site inspection without blade disassembly.


Nurses need data on patient mortality ≥48 hours of care, but nurses' skills to get these data are lacking. Nurses' lack of skills to produce scientific evidence is one of the obstacles to evidence-based practice (EBP). Research training for nurses is carried out to overcome obstacles and answer research problems. Research mentoring training was carried out for three days in June 2019 using the EBP stage. 10 nurses participated in this training. The training results reported that all nurses could plan, carry out, and report the results of the research. The research that nurses conducted was a retrospective study to collect data from 62 medical records of patients who died ≥48 hours of treatment in March-May 2019. The results of the nurse's study found that most of the patients were male (51.6%), aged over 45 years ( 66.1%), died with a medical diagnosis of Tuberculosis (27.4%), stroke (17.7%), HIV (12.9%), and with an indication of being hospitalized in the ICU (53.2%). Through training for three days, nurses can produce scientific evidence and provide recommendations for improving hospital management services. Essential research training is carried out in clinical areas to improve evidence-based practice, which in turn can improve the quality of care and health status of patients.


invaluable for an analysis of the pattern and timing of anti-Christian outbreaks. Value for money? If this were a £5 C.U.P. paperback it would be the best buy in the field of Chinese 19th-century studies. At £30 the student who wants an introduction to the subject might do better to buy four or five more specialized books for this sum, especially bearing in mind that the full Cambridge coverage of the period 1800 to 1911 will require a second, presumably equally costly, volume.


The recent advance of pervasive computing technologies promises to significantly enhance capabilities for data capture and data analysis. In this socially aware era, such technologies hold great promise and challenge for using the sensory data to understand human behavior, human mobility, human activities, and ultimately to help solve human social problems. The integration of pervasive computing and social computing has resulted in an emerging new research field in computer science—Socially Aware Computing. While the concept of social awareness has been developed in the field of Computer Supported Cooperative Work for decades, the notion of socially aware computation and communication has only recently been introduced by Alex Pentland [2005]. Socially Aware Computing brings light to the design of new software methodology, infrastructure, data analysis, and applications. This paradigm aims to leverage the large-scale and diverse sensing devices that can be deployed in human daily lives to recognize individual behaviors, discover group interaction patterns, and support communication and collaboration. Intelligent systems powered by artificial intelligence play an important role in realizing socially aware computing in various aspects, such as sensing, processing, and supporting human interaction. This special section aims to explore intelligent systems and related applications for socially aware computing. Submissions to this special issue came from an open call for papers. We received a total of 16 submissions of which 5 articles were accepted after three rounds of rigorous reviews. A large number of reviewers assisted us in the review process. In order to ensure high reviewing standards, three to four reviewers evaluated each article.


Era is a low‐molecular‐weight GTPase essential for Escherichia coli viability. The gene encoding Era is found in the rnc operon, and the synthesis of both RNase III and Era increases with growth rate. Mutants that are partially defective in Era GTPase activity or that are reduced in the synthesis of wild‐type Era become arrested in the cell cycle at the predivisional two‐cell stage. The partially defective Era GTPase mutation (era1) suppresses several temperature‐sensitive lethal alleles that affect chromosome replication and chromosome partitioning but not cell division. Our results suggest that Era plays an important role in cell cycle progression at a specific point in the cycle, after chromosome partitioning but before cytokinesis. Possible functions for Era in cell cycle progression and the initiation of cell division are discussed.


Statistics provided by the American Association of Oral and Maxillofacial Surgeons show that adults have lost at least one permanent tooth to an accident, gum disease, a failed root canal, or tooth decay. Several other adults have lost all of their permanent teeth. Therefore, the use of dental implants is very much needed. Research on dental implant designs, materials, and techniques has increased in the past few years and is expected to expand in the future due to the recent growth of the global market for dental implants and the rising demand for cosmetic dentistry. The definition of a successful implant has been refined from just achieving effective osseointegration to a precise positioning and good prosthetic outcome. To achieve such outcomes, the use of appropriate treatment planning is increasingly becoming popular. Demand from implant patients for quality and efficient treatment is increasing. Suitable treatment plans aid in placing the implants in an optimal position, as dictated by the function and aesthetics of the definitive restoration, and to avoid biomechanical complications and failure .This case report shows the accuracy of the surgical guide. If each step of this protocol is followed precisely, it is possible to deliver an optimum implant installation in terms of position and diameter and later on function at a very much reduced rate and time


This article addresses the current marginalisation of structural gender linguistics within the field of language and gender. Traditional, structuralist-minded approaches to language and gender are briefly reviewed, and it is argued that a revitalisation of the study of gendered language structures can only be achieved when such analyses reflect recent theoretical developments within the field. More specifically, this necessitates a reconceptualisation of (gendered) language structures in the light of discursive or poststructuralist theories, namely as the result of processes of discursive materialisation in language use. Also discussed at a methodological level is how de-essentialisation as a central driving force of discursive approaches to language and gender can be operationalised in various types of structural linguistic analysis. Four basic dimensions of deessentialisation are distinguished for this purpose: first, the contrastive linguistic dimension (de-essentialisation across languages); second, the historical linguistic dimension (de-essentialisation across time periods); third, the lexicogrammatical dimension (de-essentialisation across linguistic gender categories); and fourth, the pragmatic dimension (de-essentialisation across usage contexts). A contrastive sample analysis of the complexities of pronominalisation in English and German complements the discussion.


In this section, we investigate the robustness of the results reported above. First, we test the robustness of our findings to an alternative specification of the FII flow measure. Next, we examine whether our results differ for stocks associated with derivative contracts and stocks for which derivative trading is not allowed. We then employ a parametric approach to identify the impact of FII flow innovations and also attempt to uncover any asymmetry (buy side vs. sell side), as well as any nonlinear effects associated with FII flow innovations. We also recognize that FII order flow may be persistent and therefore we redefine our portfolio formation criterion in terms of cumulative innovations in FII flows over the previous 5-day period rather than in terms of the


BACKGROUND:
Dyscalculia is a part of learning disability. In ICD 10 CM diagnosis code of f81.2 it is mentioned as mathematical disorder. The populations undertaken for this study are students with poor mathematical performance in the school.

The world's population has been on a growing trend for a long time, and it is not expected to slow down in the next decades. It is important that our food production sector can support the nutritional demands current and future expansion will present. FAO data shows a growth in primary productivity over the last decades on both crop and animal production, which has been in response to the increasing food demand. One of the most import nutrient groups for human consumption is protein, as it plays various and important roles in our physiology and development. Although we can take protein from vegetables, we need a diverse source of protein and other nutrients that are not present in a single food source. This means we will need to continue expanding all aspects of agriculture, which includes fish, which are not only a good source of protein but other valuable nutrients. As more fish stocks have progressively become overfished or fully fished through the years, aquaculture became a focus of great interest. Currently over 60% of the total fish production has its origin in aquaculture. Regardless of its role in helping fulfill human food requirements, aquaculture is an industry. This means the producers will still look at profit as the final goal. The result of this is a wide range of farmed species allowing for a diverse range of products with differing markets and values. About 62% of the species farmed in aquaculture are fish being most of these freshwater species (FAO, 2016). Crustaceans are economically interesting as they are a relatively large component and have higher final market value. They only account for 8.2% of all live weight traded, but for 21.7% of value traded (FAO, 2016). With that in mind, this project was designed with the prospect of providing the author the opportunity to participate in the production of marine shrimp using typical production technologies for the Pacific white shrimp (L. vannamei) reared under pond production, in typical American conditions. This included, PL accommodation in nursery systems to grow out and harvest in ponds. As part of a nutrition team, this internship also provided the opportunity to experience daily tasks in different nutrition trials in both shrimp (L. vannamei) and fish (T. carolinnus).


Emulsion polymerization processes have important advantages over bulk and solution processes, such as the production of polymer of higher molecular weights at high polymerization rates and easier temperature control due to the low viscosity of the reaction media.

:- Guava leaf (Psidium guajava L.) contains flavonoids and tannins which have bacterial activity against Staphylococcus aureus. The use of extract as an antibacterial is not practical to use so it is made in gel form. The purpose of this study was to determine the effect of variations in the concentration of guava leaf ethanol extract on the physical properties of the gel and determine the inhibitory zones produced from the ethanol extract of guava leaves. The extract was obtained from maceration with 70% ethanol, and then it was made in gel form. The gel formula was made on the basis of CMC-Na and the ethanol extract content of guava leaves used 1, 5, and 7%. Gel evaluation includes organoleptic, homogeneity, adhesion, viscosity, pH, dispersal, and cycling tests which are then carried out with antibacterial tests using the bacteria of Staphylococcus aureus. The concentration of guava leaves ethanol extract has a significant effect on gel stability and antibacterial activity. The higher concentration of ethanol extract of guava leaves shows the higher zone of bacterial inhibition, adhesion, viscosity, and decreased pH and gel dispersion.


A poly(methacrylamide-co-methylmethacrylate) (abbreviated PMAA-MMA) polymer support was studied for supporting a heteropolyacid (tungstophosphoric acid, H3PW12O40) with its surface positively charged in the polymerization step. PMAA-MMA supports could be obtained in a porous form by eliminating template reagent molecules (benzylmalonic acid) combined with properly selected monomer (methacrylamide). The amount of amine groups in PMAA-MMA directly determined the amount of H3PW12O40 impregnated, because the amine groups induced a positive charge on the PMAA-MMA surface. Finally, H3PW12O40/PMAA-MMA showed better acid catalytic activities than unsupported H3PW12O40 in alkylation of 1,3,5-trimethylbenzene with cyclohexene, which confirmed that PMAA-MMA supported H3PW12O40 effectively.


A photoactive photosystem I complex has been purified from the filamentous, nitrogen-fixing cyanobac- terium Anabaena variabilis ATCC 29413. Cells were broken using glass beads, and the membrane fraction was solubilized with 8-dodecyl maltoside followed by two rounds of fast protein liquid chromatography on anion exchange columns. The polypeptide composition of the isolated complex was determined by sodium dodecyl sulfate-urea-polyacrylamide gel electrophoresis and N-terminal amino acid sequencing of the fractionated proteins. The purified complex consists of at least 11 proteins, identified as the PsaA, PsaB, PsaC, PsaD, PsaE, PsaF, PsaI, PsaJ, PsaK, PsaL, and PsaN proteins. The spectrum of the flash-induced absorb- ance change measured between 670 and 830 nm shows that the purified complex contains 99 f 11 chlorophyll a molecules per P700, the primary donor in photosys- tem I. The kinetics of the rereduction of oxidized P700 following an actinic flash indicate that forward elec- tron transfer from P700 to the FJFB iron-sulfur center


The purpose of this paper is to examine multiple dimensions of reflexive and reciprocal mentorship as they work through the fear of teaching challenging and politically charged ideas.,This piece is a case study of the complex instances of reciprocal mentorship within a teacher education program. Objects of analysis included the informal educational experiences from the bi-monthly meetings and student-teaching experiences. Semi-structured interviews, field notes, interpersonal discussion and the authors' own reflections were used as data sources.,The authors found that having difficult conversations in informal spaces provided social studies teacher candidates with the opportunity to get more comfortable with challenging conversations; that mentorship is helpful when shifting context between formal and informal spaces; and that once these teachers grew more comfortable, they moved from mentee to mentor with support and guidance from their own mentors. The authors conclude by providing several implications for pre-service teachers, teacher and teacher educators, as they help social studies practitioners work with and beyond the politics of fear.,Limitations such as subjectivity, generalizability and implementation exist. Factors such as personality, program, cultural background, lived experience and other elements played a role in the findings. Therefore, the authors do not suggest these are monolithic claims about the nature of mentorship, teacher education or teaching, but rather the authors wish to share these findings and recommendations.,The authors argue that three major findings emerged from the data. First, informal spaces are valuable for initiating difficult conversations among mentors and mentees. Second, shifting between formal and informal spaces can be uncomfortable, but allow for mentoring opportunities during these challenging instances of becoming. Third, moving from mentee to mentor includes valuable reciprocal mentorship within a learning community.,This research project is grounded in the needs of the participants and researchers. To the authors' knowledge, a project of this type with similar participants has not been done.


The paper presents the calculated results obtained by the author for critical Mach numbers of the flow around two-dimensional and axisymmetric bodies. Although the previously proposed method was applied by the author for two media, air and water, this chapter is devoted only to air. The main goal of the work is to show the high accuracy of the method. For this purpose, the work presents numerous comparisons with the data of other authors. This method showed acceptable accuracy in comparison with the Dorodnitsyn method of integral relations and other methods. In the method under consideration, the parameters of the compressible flow are calculated from the parameters of the flow of an incompressible fluid up to the Mach number of the incoming flow equal to the critical Mach number. This method does not depend on the means determination parameters of the incompressible flow. The calculation in software Flow Simulation was shown that the viscosity factor does not affect the value critical Mach number. It was found that with an increase in the relative thickness of the body, the value of the critical Mach number decreases. It was also found that the value of the critical Mach number for the two-dimensional case is always less than for the axisymmetric case for bodies with the same cross-section.

Macronutrients are very important for plant development and growth. They can be important constituents of various structural units and redox sensitive agents. Moreover, macronutrients can improve the yield, quality and growth of crops. Now a day, biotechnologists, plant physiologists and ecophysiologists have been investigating other blind features of these minerals, as macronutrients are involved in every aspect of plant life. Each macronutrient has its own characteristic features, and are involved in different metabolic processes of plant life.


Paper banknotes are a case in point. As they were easy to carry, they made commerce more straightforward. But their success did not come easily. Attempts by central banks to issue banknotes in the 17th century resulted in too many being issued and even defaults, raising questions about their effects on stability and, ultimately, on the credibility of the sovereign. Yet modern banknotes eventually enhanced the benefits of central banking for society at large.[ ]


The use of non-isothermal methods for finding the kinetic parameters (E, Z & Δ S*) and the mechanism of decomposition of the complex, [Pr (C15H9O4)32H2O] is reported. The complex decomposes in two well defined steps involving random nucleation mechanism. First step involves the dehydration of the complex and the second step involves the loss of the ligand moiety.


The amount of sales profit is one of the indicators of the manufacturer's business performance. This is the financial result from the main activity of the manufacturer, which can be carried out in any form registered in its charter (and not prohibited by law). The product sales profit is defined as the difference between the proceeds from sales (without value added tax and excise taxes) and the costs of production and sales included in the product costs.


Summary: Thirty‐two ovulatory women had serial ultrasound measurements of uterine volume, endometrial thickness and leading follicular diameter compared with serum oestradiol, testosterone and sex‐hormone binding globulin. Follicular diameter, endometrial thickness and uterine volume were significantly correlated with serum oestradiol. The day before ovulation was characterized by maximal values for oestradiol, testosterone, luteinizing hormone, endometrial thickness, uterine volume and leading follicular diameter. Leading follicular diameter and endometrial thickness in particular, appear to be useful parameters to indicate impending ovulation.


ABSTRACT It is suggested that the emergence of a more peaceful and prosperous Africa depends on the implementation of "African solutions for African problems" and that this be done through the creation of regional security communities. This may sound right, but because of internal and external factors, as a policy it is cynical, hypocritical, and misleading. There is a fundamental contradiction between the concept in theory and in practice. This paper shows that the complex problems in Africa are part of the global systemic interaction that often hinders the potential of the African Union and its regional economic communities' ability to become security communities. I argue that since Africa's problems are not only African but also global problems, solutions for Africa can only be global-systemic.

Recently, sewage sludge as a cheap organic fertilizer and rich in nutrients has received considerable attention in many countries. The aim of this study was to determine the effects of Tabriz petrochemical factory ' s biological sludge on some soil biochemical and chemical indices such as the number of microorganism s, substrate-ind uced respiration, electrical conductivity, hot water-soluble carbohydrates and total nitrogen as well as their temporal variations in a calcareous soil selected from Mohaghegh Ardabili University ' s Research Station. The greenhouse experiment was done as a factorial randomized complete block design with three replicates. The first factor was the rates of applied sludge as 0 (control), 25, 50, 75 and 100 ton/ha of air dry soil and the second factor was the incubation times as 30, 90 and 180 days. Incubation of the treatments was done at 22±4 ◦ C and 0.75 field capacity moisture for 6 months. The results indicated that the all rates of applied sludge significantly increased the average of number of microorganisms, substrate-induced respiration, electrical conductivity, hot water-soluble carbohydrates and the percentage of soil total nitrogen 23, 53, 105, 58 and 138% as respectively compared to the control. Also, the effect of incubation time on all parameters except for the number of microorganism s was significant. The rates of carbohydrate and nitrogen in sludge treatments significantly increased at 180 days rather than the 30 days.


A model of multiple lossy microstrip lines on IC chips or cards is developed for direct time domain simulation of interconnections at a low computational cost. It is concerned with lines of equal widths with losses independent of frequency. Measurements of the step response in the tens of picoseconds range of three coupled lines on GaAs validate the model in severe test conditions of strong ohmic losses.


This study presents the results of a field experiment conducted for assessing the crop health status of several barley and oat crop fields in Prince Edward Island, Canada. The crop fields were mapped with an unmanned aircraft system (UAS), and the crop health status was assessed through the green area index (GAI) and vegetation indices (VIs). GAI maps were produced from the UAS imagery and VIs used machine learning pipelines with several regression algorithms (multiple linear models, support vector machines, random forests, and artificial neural networks) along with a feature selection strategy. The random forests algorithm was shown to be the best algorithm for GAI prediction with an average relative root mean square error of 10.86% and a mean absolute error of 0.67. The resulting GAI maps and the regression feature space were classified with random forests to discriminate between vigorous and stressed crop areas. We achieved a mean overall accuracy of 94%. The limits of the study are also presented.
