FIELD: chemistry. SUBSTANCE: synthetic gas is obtained through catalytic reforming with water vapour of hydrocarbon material in parallel, in an automatic reformer with water vapour and in one or more successive reformers with water vapour. The heat for reforming reaction with water vapour in one or more reformers with water vapour is provided for, through indirect heat exchange with combined gas streams, flowing from one or more reformers with water vapour and the automatic reformer with water vapour. The catalyst in at least one of the reformers with water vapour is granulated or is in form of a catalytic medium. A gas containing carbon oxide is added to the raw material before reforming with water vapour in the automatic reformer with water vapour and/or before reforming water vapour in one or more reformers with water vapour. Gas, containing carbon oxide with ratio of atomic hydrogen to atomic carbon less than 4.5, is added in a quantity which yields a product with molar ratio of hydrogen to carbon oxide lying, approximately, between 1.8 and 2.3. EFFECT: increased output of synthetic gas. 9 cl, 4 tbl, 2 ex, 2 dwg


OBJECTIVE
To investigate the effect of urological surgery on ureteric peristaltic activity.

SUBJECTS AND METHODS
Ureteric peristalsis was assessed in a sample urological population (n = 29 patients) and the findings compared with a control population (n = 14 patients).

RESULTS
The incidence of disordered peristalsis was significantly increased (P < 0.05) following urological surgery and, in particular, the incidence of retrograde peristalsis was very significantly increased (P < 0.01) following ureteric division and re-anastomosis.

CONCLUSION
The results of this study are consistent with a central role for myogenic activity in the conduction of ureteric peristalsis in man.


Introduction: Acute inflammation process of the pancreas with or without involvement of surrounding tissues and remote organ systems is termed as Acute Pancreatitis (AP). Contrast Enhanced Computed Tomography (CECT) if performed immediately may underestimate the severity. Therefore, ultrasound examination remains the first imaging diagnostic method in suspected cases of AP. The sensitivity of B-mode sonography for the early diagnosis of AP can be increased by the detection of an increase in pancreatic tissue stiffness with Shear Wave Elastography (SWE). Aim: To evaluate the efficacy of SWE in the analysis of AP. Materials and Methods: A cross-sectional study was conducted in Tertiary Care Hospital attached to Mysore Medical College and Research Institute, Mysuru, Karnataka, India, from August 2019 to September 2019. The pancreatic parenchyma of 30 patients with symptoms of AP that included acute onset of severe central epigastric pain, poorly localised tenderness and pain increased by supine positioning radiating to the back. The study also included 40 healthy, asymptomatic volunteer who were examined using B-mode sonography and SWE. Computed Tomography (CT) was performed in all patients with AP with a SEIMENS SOMATOM DEFINITION EDGE 128 slice CT scanner. Elastographic measurements were performed and quantitative SWE values represented in kilopascal (kPa) of the patients and asymptomatic volunteers group were compared. Patients' amylase and lipase levels were done by biochemical tests. Descriptive and Inferential statistical analysis was carried out in the present study. Student's t-test (two tailed, independent), Leven's test for homogeneity of variance and Chi-square test was used to find the significance of study parameters. Results: The mean SWE values for the asymptomatic volunteers with normal pancreatic parenchyma were 9.53±2.62 kPa. The mean SWE values for the pancreatic parenchyma of the patients with AP were 17.23±6.24 kPa. The mean SWE value for the patients with AP was significantly higher than the value for the control group (p<0.001). A SWE cut-off value of 13.5 kPa was associated with 70% sensitivity and 92.5% specificity for diagnosis of AP. Conclusion: For the diagnosis of AP at initial hospital admission, SWE can be used as it is a rapid, radiation-free, and non- invasive tool. It is a useful imaging method with high sensitivity and specificity for the diagnosis of AP.

SUMMARY The techniques of lymphatic mapping and sentinellymphadenectomy have been increasingly popular inthe 8 years since their introduction. 1 The techniqueswere initially developed for the management of pa-tients with cutaneous melanoma, but are now widelyapplied in breast carcinoma and are under investiga-tion in the management of other forms of cancer.Despite this wide enthusiasm there is little unanimityregarding the exact details of the technical steps thatare required for successful application of the ap-proach, and published guidelines remain few. Withthis in mind, a conference on sentinel lymphadenec-tomy in cutaneous malignancies was held in Augs-burg, Germany, in March 1999, following which agroup of individuals who had extensive experiencewith the approach convened a committee of expertsand was charged with developing a consensus on thetechniques necessary for the optimum application of theapproach. This article is the result of these deliberationsand provides detailed and practicable recommendationson patient selection, preoperative and intraoperative lo-calization of the SLNs, pathologic assessment of theSLNs, and the correct disposition of lymph node tissuesfor diagnostic and investigative purposes.


Unlike traditional phased-array-radar, multiple-input multiple-output (MIMO) radar is capable of achieving more degrees-of-freedom (DOF) and larger virtual aperture (VA) for the direction-of-arrival (DOA) estimation. In this letter, a new universal antenna array approach employing a one-level transmitter (Tx) and generalized receiver (Rx) is presented for MIMO radar to enhance the DOA estimation performance. The proposed configuration significantly improves the DOF capacity and expands VA by utilizing difference co-array of sum co-array method. The first-level of the Rx and a Tx with increased inter-element spacing is constructed using the nested-coprime array with displaced sub-arrays structure. The proposed Rx is transformable, generic, and easier to realize. It exploits symmetrical array geometry, such that once the initial-level is designed, the remaining stages will be known. The Rx also reveals an inbuilt Tx. Moreover, it achieves increased DOF and enlarged VA, reflecting the multifaceted advantages of the new Rx approach. The configuration is also benefited with closed-form expressions for VA, sensor locations, and DOF. Simulation results demonstrate the superiority of the proposed MIMO radar.


The eastern flank of the Front Range in north central Colorado shows a remarkable series of potholes related to the early Pleistocene glaciation of the region. The areas concerned are deeply and thickly pitted with thousands of glacially carved potholes. The bearing of these ancient potholes on the condition of the ice during their formation indicates unusual features of crevassing and surface ablation. The potholes are directly linked up with ancient cirques, U-shaped valleys, striae, and perched bowlders in the chain of evidence which indicates that these early Pleistocene glaciers covered 75 to 80 per cent of the region and had many of the characteristics of an ice cap with pendant valley glaciers, fringing well out to the foothills.


Allelopathic effects of the donor plants are mostly regarded as harmful to target plants such as traditional crops. Traditional crops play pivotal role as staple food for rural communities and hence ensuring food security. Study of the allelopathic effects of Androstachys johnsonii Prain on the germination and growth of Zea mays L. and Vigna subterranea (L.) Verdc was conducted. Different plant leachates concentrations of 0.675%, 1.25%, 2.5% and 5% were prepared through serial dilutions. Germination bioassays were arranged in a complete randomized setup of three replicates for each treatment for seven days. Germination rates were calculated, radicle and hypocotyl lengths were also measured. Germination rates of Z. mays L. and V. subterranea (L.) Verdc. ranged from 50 - 100% and 18 - 76%, respectively. Significant differences of P< 0.005 were noticed from the germination rates of V. subterranea (L.) Verdc subjected to high concentrations of different extracts used. Statistically there was no significant differences between germination rates of Z. mays L. treated with all concentrations of leaf leachates against germination rates of the seeds treated with distilled water. Outstandingly, the germination rate and early growth of Z. mays L. were promoted by less concentrated extracts of leaf, root, stem bark and soil which then suggest future use of allelochemicals from Androstachys johnsonii Prain for promotion of maize plant productions. Based on the beneficial attributes of allelochemicals from Androstachys johnsonii on the germination and growth of Z. mays L., planting of Androstachys johnsonii Prain in maize fields is highly recommended.


long and short vowels. Thus Richards enters Us for both /lis/ "list" and /liis/ "smooth", while /karan/ "eager" and /ksraan/ "early" are both listed as keran. A further criticism must be directed at Richards' "derivations", which in many cases consist of cognates and/or synonyms in related languages (especially Malay) or even of homophones with no apparent etymological relationship to the headword. For example, alir "hook for catching crocodiles" is referred to Malay alir "to flow". Richards uncritically accepts the often faulty etymologies of Wilkinsons's Malay dictionary (e.g. deriving Iban piak, Malay pihak, from a mythical Arabic flhak) and also adds a few of his own. For instance, tir "tar" and sekup "spade" come not from English tar and scoop but (through Indonesian Malay) from Dutch teer and schop respectively. But these are minor weaknesses which do not detract from the valuable contribution which Richards has made to knowledge of Iban language and culture.


An investigation has been undertaken using laser-Doppler velocimetry and flow visualization to better understand the interactions of turbulent eddies with the component processes of coagulation. Coagulant-aid activation, floc structure and density, and aggregate integrity are of particular interest. A 20 liter flocculation basin with two different paddle assemblies was constructed and examined extensively. The perforated blades produced a far mote energetic gross circulation at modest rates of rotation than obtainable with the hardware cloth paddles, and a larger initial aggregate growth rate. The hardware cloth paddle assembly appeared to produce greater floc volume fraction at large aggregate diameters, however. The objective of this study was to determine the extent to which the turbulent energy distribution can be manipulated to produce desired floc properties or floc growth patterns.


A search for neutral penetrating particles has been made by use of an 800-GeV proton beam incident on the magnetized beam dump of the Fermilab experiment 605/772 spectrometer. Limits on the mass and couplings of such particles are presented. These improve on the limits obtained from a previous run with the same apparatus, and axions coupling only to {ital e}{sup +}{ital e{minus}} are now ruled out up to masses of 2.7 MeV/{ital c}{sup 2}.


ABSTRACT The hypothesis of no significant difference in errors between observed (historical) and downscaled global circulation model (GCM) rainfall and corresponding errors in simulated runoff was tested. The percentage difference in mean and standard deviation, normalized errors and normalized bias metrics were used. The ACRU hydrological model was used to simulate runoff. Results indicated that errors in rainfall lead to amplified errors in simulated runoff. A 10% error magnitude in mean rainfall was amplified three times in mean runoff. Rainfall variability was amplified by twice as much from rainfall to simulated runoff. These findings indicate that uncertainty in input downscaled rainfall is amplified in simulated runoff, hence the quality of input rainfall is a strong determining factor of the simulated runoff. Ultimately, there is a need for continuous improvement in the GCM downscaling process, particularly model process description, so as to minimize uncertainties due to GCM model description. EDITOR A.

Writing skill develops slowly and lags some way behind other skills EFL learners of English have difficulty organizing their ideas at clause and text level to produce a coherent text. Given this, the study was an attempt to examine the effect of picture story on the organization of ideas in the narrative text. Participants (n= 60) were divided into two experimental and control groups. Then the Experimental and control groups were invited to produce a narrative text with and without pictures respectively. When the texts were analyzed, it was revealed that in the texts produced with pictures, the number of NPs to begin an episode outnumbered those produced without pictures. It is more common in English to begin a new episode with an NP and then in the next mentions use a pronoun to create a more smooth text to reduce the cognitive load on readers and/or listeners. Also a close examination of the data revealed that pictures contributed to focus the subjects' attention on the text organization of narrative genre in terms of relating events in the text by employing temporal/causal relations to create semantic relations in the text. The statistical analysis of a Matched t-test, by applying SPSS version 13, was performed and it was revealed that the mean differences between the performances in the two tasks were meaningful, rejecting the null hypothesis and confirming the hypothesis that picture story helps to create coherence in the narrative text  in terms of organization.


Background: Multiple myeloma (MM) is the second most common hematological malignancy. This disease remains incurable as nearly all patients will relapse and become refractory to established MM therapy. Thus, new treatment option for relapsed or refractory (R/R) MM is needed, particularly those with different mechanisms of action. One such approach is to inhibit histone deacetylase (HDAC) and produce synergistic anti-myeloma activity via mechanisms of epigenetic modulations. In 2015, panobinostat was approved by US FDA as the first HDACi to treat R/R MM in combination with bortezomib and dexamethasone.
 Bisthianostat is a novel bisthiazole-based HDACi evolved from the thiazole-thiazoline cap group in natural product Largazole (Nan et al., ACS Med Chem Lett. 2014). It is orally available and displayed inhibition against a series of MM cell lines. Here we presented preliminary in-human findings from CH-020PI study, an ongoing phase 1 study of bisthianostat. (Trial registered at ClinicalTrial.gov: NCT03618602)
 Methods: CH-020PI is a first-in-human study to investigate the safety, tolerability, pharmacokinetics, and efficacy of bisthianostat in R/R MM patients. It is a single center, open-label, single arm, dose escalating phase I study. A standard 3+3 cohort design with 100mg as the starting dose was used to determine the maximum tolerated dose of bisthianostat. This study comprised two phases: a pharmacokinetics phase and an expansion phase. In the pharmacokinetics phase, a single-dose of bisthianostat was administered on day 1, and then multiple-dose was administered on a twice-weekly schedule for 4 consecutive weeks. Patients in the expansion phase received continuous bisthianostat twice weekly until progressive disease or unacceptable toxicities.
 Results: Until 30 June 2019, 8 patients were enrolled at 3 dose levels from 100 to 400mg. The median age at enrollment was 62 years (range, 51-70 years). The median number of previous lines of therapy was 5 (range, 2-6). Per protocol, all of 8 patients were evaluable for pharmacokinetics, toxicities and efficacy. In the pharmacokinetic evaluation, for all the 8 patients tested at day 1, the peak concentration of bisthianostat was reached within 2.3 hours; half life time were around 4 hours; bisthianostat uptake represented by AUClast were in good proportion to the level of dose as 100, 200 and 400mg, respectively. Similar results were observed at day 28. Any grade hematological treatment-related adverse events (AEs) occurred in 4 of 8 patients (50%), while grade 3/4 hematological AEs occurred in 2 (25%) patients. Any grade non-hematological treatment-emergent AEs were observed in 3 (37.5%) patients; no grade 3/4 non-hematological AEs were reported. No patient discontinued the treatment of bisthianostat due to AEs. Except patient 007 (200mg cohort) experienced a grade 2 nausea, no patients experienced diarrhea, nausea, or vomiting. It is worthy to note that gastrointestinal toxicity is common with the use of panobinostat, a FDA-approved HDAC inhibitor. Overall single-agent efficacy was modest, and stable disease (SD) was observed in 4 (50%) patients. At the time of data cut-off for statistical analysis, no dose-limiting toxicity has been observed.
 Conclusions: Bisthianostat proved to be well absorbed and tolerated. It exhibited modest anti-tumor efficacy in our cohort of heavily pretreated patients with R/R MM. This phase I clinical trial is currently ongoing, and future trials should compare different doses and schedules of the combination in order to optimize the treatment tolerability and enhance its efficacy.

Development of resistance limits transferability of most anticancer therapies into curative treatment and understanding mechanisms beyond it remains a big challenge. Many high resolution experimental observations show enormous intratumor heterogeneity at molecular, genetic and cellular levels which is made responsible for emerging resistance to therapy. Therefore, researchers search techniques to influence development of intratumor heterogeneity, which requires understanding its role within the context of integrative, logically consistent, framework, such as evolutionary theory. Although it is agreed that intratumor heterogeneity increases probability of the emergence of therapy resistant clones, more instructive role of its structure in the process of cancer dynamics and metastasis is needed. In the paper, intratumor heterogeneity is viewed as a product of two, in general stochastic, processes, evolutionary optimization and changing environment, respectively. In evolutionary theory, common risk-diversifying strategy displayed by isogenic populations in unpredictably changing environments is bet-hedging. We suggest, that the structure of intratumor heterogeneity is evolutionary trait evolving to maximize the clonal fitness in changing (or uncertain) environment and that its structure corresponds to bet-hedging strategy. We advocate our view by reviewing and combining important cancer relevant concepts.

Beta gallium oxide (Ga2O3) has received much attention recently as a viable candidate for the nextgeneration material for power electronics and photonic applications, with its unique advantages, such as the wide bandgap (~ 4.9 eV), high breakdown voltage, and optical transparency up to UV range. Recent advances in high quality Ga2O3 thin film growth, such as using molecular beam epitaxy or chemical vapor deposition, combined with the material's availability as inexpensive bulk substrates have opened new exciting opportunities for the fabrication of novel Ga2O3 devices. Despite the advances, many of the fundamental properties of Ga2O3 are yet to be understood clearly. As in many other oxide-based transparent semiconductors, point defects and their complexes can dictate the properties of Ga2O3. Various spectroscopic methods as well as theoretical calculations have provided useful insights on the nature of the point defects and complexes in Ga2O3. Regardless, what has been missing in the field is the detailed information on the atomic scale structure of the defects and complexes in Ga2O3. Such information is crucial to determine how the atomic scale defects relate to many of the unanswered questions regarding the unique properties of Ga2O3, including how point defects and impurity atoms influence the formation of trap states, how the dopant atoms are compensated, and what is the exact origin of the difficulty in doping of Ga2O3 (especially p-type).


The current paper, based on field research in two rural areas in Greece, focuses on the attitudes and perceptions of both farmers-employers and immigrants on various aspects of the latter's integration into the local socio-economic system(s). The results show that farmers are positive as far as immigrants' contribution to agriculture is concerned but hold 'defensive' views and rather ambivalent, ethnocentric attitudes in relation to a multicultural local society. Additionally, farmers' views are, more or less, differentiated between the two research areas. Finally, immigrants' views denote a positive perception of their integration into their host societies.


Objective To investigate the expression and distribution characteristics of CD15 and CD133 in gliomas,and analyze the correlation between CD15 and CD133.Methods Immunohistochemistry stainning was used to detect the expression of CD15 and CD133 in gliomas.The integrated optical density(IOD) of CD15+ cells and CD133+ cells in different grades of gliomas was calculated by Image-Pro Plus 6.0 Image analysis software.Results Along with the tumor grade increased,the number of CD15+ and CD133+ cells and their niches was increased significantly.The IOD was significant difference between CD15+ cells and CD133+ cells in high-or low-grade gliomas(z=-3.432,P=0.001;z=-4.192,P=0.000);The IOD of CD15+ cells was positive correlation to CD133+ cells(r=0.535,P=0.000).CD133 also expressed in fat cells of gliomas with fat cells components.CD133+blood vessels could be observed.Conclusion The advance of tumor grade,was related to the increasing of CD15+ and CD133+ cells and their niches.CD15 and CD133 expression was positive correlation.The over-expression of CD133 in fat cells of glioma suggested a poor clinical prognosis.


Three Word Ways articles have been written by Dmitri Borgmann ( February and May 1977) and Pamela Brang (August 1977) to support the proposition that' all words are interesting' from a logological stand point. As noted in the May and August Colloquies, the results left some thing to be desired. For example, Borgmann's efforts included two transposals and a substitute-letter transposal to nonexistent words or name s; a refe rence to a I dictionary combination I (a sequence of words occur ring somewhere in the text of a dictionary, no more worth men tion than any sequence from any other text); and a reference to a dif ferent word (' subcontinent' was identified as the noun base of 1 subcon tinental' which is interesting because it contains AEIOU in reverse or der, but isn't the object to find a property of 'subcontinent' itself?).


During fixed orthodontic treatment, there is great possibility that the dental enamel could be damaged due to the process of debonding the bracket. Enamel cracks are one of the most common aspects that can develop or increase during debonding. This review aimed to conduct an examination of cracks in the enamel that occur both prior to and following metal or ceramic brackets being debonded.


Adsorption is a cost-effective method that is successfully used to remove dyestuff from waste. However, this method requires filtering that takes a long time to separate the adsorbent medium. The Fe3O4/Volcanic soil composite was prepared to obtain adsorbates that can respond to the magnetic field so that the adsorbate is easily separated from the adsorbent medium after adsorption. The experimental results showed that physical mixing has adsorption capability better than composite. However, the physical mixing has weaker magnetic strength such that in the adsorbate separation process from the adsorbent medium can not be performed using a magnet. The composite has a homogeneous surface and can adsorb only one adsorbate molecule for each of its adsorbatet molecules as evidenced by the obtained Langmuir isotherm.

Abstract Novel phospholipid derivatives of betulin (1), betulin diacylphosphatides (3a, c), were obtained by coupling betulin (1) with 1,2-dipalmitoyl-sn-glycero-3-phosphatidic acid (2a) or its salt (2b) or with 1,2-diacyl-sn-glycero-3-phosphatidic acid (2c), obtained from phosphatidylcholine isolated from egg yolk. The syntheses were carried out with application of various coupling agents: 2-mesitylenesulfonyl chloride, p-toluenesulfonyl chloride, and N,N′-dicyclohexylcarbodiimide and in the presence of 4-dimethylamino-pyridine in pyridine. GRAPHICAL ABSTRACT


This study proposes innovative methods for the time-fractional modified Degasperis–Procesi (mDP) and Camassa–Holm (mCH) models of solitary wave solutions. To formulate the concepts of the homotopy perturbation transform method (HPTM) and Elzaki transform decomposition method (ETDM), we mix the Elzaki transform (ET), homotopy perturbation method (HPM), and Adomian decomposition method (ADM). The Caputo sense is applied to this work. The solutions to a few numerical examples of the modified Degasperis–Procesi (mDP) and Camassa–Holm (mCH) are shown for integer and fractional orders of the issues. The derived and precise solutions are compared using two-dimensional and three-dimensional plots of the solutions, confirming the suggested method's improved accuracy. Tables are created for each problem to display the suggested approach's results, precise solutions, and absolute error. These methods provide the iterations as a series of solutions. To show the proposed techniques' efficiency, we compute the absolute error. It is evident from the estimated values that the approaches are precise and simple and that they can therefore be further extended to linear and nonlinear issues.


A metalloorganic capsule was synthesized where the ligand is a derivative of heptazine with three carboxylic groups that are coordinated to CuII cations, forming paddle-wheel motifs. Each nanocapsule is neutral, with 12 CuII centers and 8 ligands adopting a rhombicuboctahedron shape. It has almost 3 nm diameter, and the main intermolecular interactions in the solid are π··· π stacking between the C6N7 heptazine moieties. The nanocapsules can form monolayers deposited on graphite as observed by atomic force microscopy, which confirms their stability in solution.


From 1930 to 1945, the Japanese colonial government of Korea pursued a policy of requiring attendance at the rituals of the State Shintō cult. Failure to comply met with severe punishment with 50 Koreans being known to have died as a result of their opposition to shrine worship. Although unquestionably holding nationalistic sentiments, these martyrs died as a result of their religious rather than their political beliefs. Refusal to comply with the colonial regime's demands led to differences within the Christian community, which in turn led to the subsequent creation of denominations which separated themselves from groups which were perceived to have compromised their Christian witness.


Luminescent bacteria in the family Vibrionaceae (Bacteria: γ‐Proteobacteria) are commonly found in complex, bilobed light organs of sepiolid and loliginid squids. Although morphology of these organs in both families of squid is similar, the species of bacteria that inhabit each host has yet to be verified. We utilized sequences of 16S ribosomal RNA, luciferase α‐subunit (luxA) and the glyceraldehyde‐3‐phosphate dehydrogenase (gapA) genes to determine phylogenetic relationships between 63 strains of Vibrio bacteria, which included representatives from different environments as well as unidentified luminescent isolates from loliginid and sepiolid squid from Thailand. A combined phylogenetic analysis was used including biochemical data such as carbon use, growth and luminescence. Results demonstrated that certain symbiotic Thai isolates found in the same geographic area were included in a clade containing bacterial species phenotypically suitable to colonize light organs. Moreover, multiple strains isolated from a single squid host were identified as more than one bacteria species in our phylogeny. This research presents evidence of species of luminescent bacteria that have not been previously described as symbiotic strains colonizing light organs of Indo‐West Pacific loliginid and sepiolid squids, and supports the hypothesis of a non‐species‐specific association between certain sepiolid and loliginid squids and marine luminescent bacteria.


Objective To investigate the clinical efficacy and safety of Endostar combined with FOLFOX4 regimen for advanced gastric cancer.Methods Fifty-three cases of advanced gastric cancer treated in our hospital were randomly assigned to receive recombinant human endostatin injection(Endostar) plus FOLFOX4 regimen(n=31) or FOLFOX4 regimen monotherapy(n=22).The clinical efficacy,levels of serum tumor marker,and the incidence of adverse events were compared between two groups.Results The effective rate in patients receiving Endostar plus FOLFOX 4 regimen was significantly higher than that in patients receiving FOLFOX4 regimen monotherapy(58.06% vs 31.82%,χ2=13.913,P0.05).The levels of serum CEA,CA50,CA125,CA153,and CA199 were lower in En dostar-treated patients as compared with those treated by FOLFOX4 regimen monotherapy(P0.05).No significant difference in adverse events was found between two groups(P0.05).Conclusion Endostar combined with FOLFOX4 regimen can effectively reduce progression of advanced gastric cancer and can be well tolerated by patients.

The purpose of this research is to know the effect of debit variation on Chemical Oxygen Demand (COD) reduction efficiency in artificial domestic wastewater after being processed using aerobic biofilter reactor. The biofilter was maintained at continues flow and aerobic state. The debit variations used were 0.56 l/h for 72 hours retention time, 0.83 l / h for 48 hours retention time and 1.67 l/h for a 24 hour retentione time. Efficiency of COD decreased at 0.56 l/hr variation was 84%, at 0.83 l / h was 86% while at 1.67 l/h was 75%.

To describe placental location in the first trimester of pregnancy and subsequent placental migration in women with and without a history of previous Cesarean delivery.


The following article presents an application of game-theoretical models, meant to describe and explain the conditions of stability of coalitions created within decision-making bodies. The basis of the presented approach is the concept of power indices, as well as subadditivity and superadditivity of coalitions. The article also illustrates how to apply the model of oceanic games for analyzing assemblies consisting of many participants. These studies are exemplified by the results of research on the decision-making processes in the Sejm (the lower house of the Polish parliament) and among delegates of the 2008 U.S. presidential nominations of the Democratic Party, which lead to clear, intuitive interpretations, useful for explanations of processes occurring within the decision-making bodies.


The papers presented and discussions held at the conference showed that radioisotope applications are not only growing in variety but also rapidly emerging from the stage of officially sponsored research and experiment to that of standard industrial practice. The resulting change is of more than purely technical interest: in some of the advanced countries it has already benefited industry to the extent of millions of dollars. Recognition of this change was reflected not only in the results reported at the conference but also in its composition. Unlike at previous meetings of this kind, many of the delegates came from technical and industrial groups and a large number of the 150 papers related to or had some possible bearing on industrial application.


Absorbance and fluorescence intensity of fluorescein decreases in the presence of aqueous nonionic micellar solution of Tween 20 (polyoxyethylene sorbitan monolaurate), Tween 40 (polyoxyethylene sorbitan monopalmitate), Tween 60 (polyoxyethylene sorbitan monostearate) and Tween 80 (polyoxyethylene sorbitan monooleate). Photovoltage generation using fluorescein dye in aqueous micellar solutions of Tweens (20, 40, 60 & 80) was studied using a photogalvanic cell. The characteristics of the cell were determined. An attempt has been made to analyze the results on a physicochemical basis.


Rayleigh showed that inviscid flow is unstable if the velocity profile has an inflection point in parallel flows. However, whether viscous flows is unstable or not is still not proved so far when there is an inflection point in the velocity profile. Fluid viscosity has showed dual role to the flow instability. In this paper, it is demonstrated for the first time that viscous parallel flow with inflectional velocity profile is sufficient for flow instability.


Detailed structures of the Vela pulsar (PSR B0833-45, with a period of 89.33 ms) are predicted by adopting a recently constructed unified treatment of all parts of neutron stars: the outer crust, the inner crust, and the core based on modern microscopic Brueckner–Hartree–Fock calculations. Taking a pulsar mass in the range from 1.0 to 2.0 M⊙, we calculate the central density, the core/crust radii, the core/crustal mass, the core/crustal thickness, the moment of inertia, and the crustal moment of inertia. Among them, the crustal moment of inertia could be effectively constrained from the accumulated glitch observations, which has been a great debate recently, known as the "glitch crisis." Namely, superfluid neutrons contained in the inner crust, which are regarded as the origin of the glitch in the standard two-component model, could be largely entrained in the nuclei lattices, and then there may not be enough superfluid neutrons (∼4/5 less than the previous value) to trigger the large glitches (Δν/ν0 ∼ 10−6) in the Vela pulsar. By confronting the glitch observations with the theoretical calculations for the crustal moment of inertia, we find that despite some recent opposition to the crisis argument, the glitch crisis is still present, which means that besides the crustal superfluid neutrons, core neutrons might be necessary for explaining the large glitches of the Vela pulsar.


In the indoor environment, mites and fungi are two of the most important causes of asthma and rhinitis in people. Although these two subjects are often studied separately, to do so ignores the important ecological relationship between them. For example, fungi may be a source of nutrients, providing the sterols and vitamins required by one of the most important house-dust mites, Dermatophagoides pteronyssinus. In addition, two other mite species also found in the indoor environment, Acarus siro and Tyrophagus putrescentiae, are attracted by fungi and feed on some species of them. In return, these two mite species are capable of inoculating the micro-organisms into clean food commodities. This review is an attempt to highlight the complex interaction between mites and fungi and to give an overview of our knowledge of this microscopic world. It also hopes to give a clearer understanding of the mechanisms by which fungicides can control, or not, the development of domestic mite populations. Introduction .. Mites are Chelicerata, belonging to the class of Arachnida and to the subclass of Acari. Among the thousands of species identified today some live in houses and are therefore brought together under the term 'domestic mites'. These domestic mites are themselves divided into housedust mites and stored food mites, according to their usual habitat. A number of them are responsible for respiratory and cutaneous allergies (allergic rhinitis, asthma, dermatitis) in sensitive individuals [1-9]. The most widespread species of house-dust mites in Europe and in the USA are Dermatophagoides pteronyssinus, Dermatophagoides farinae, and Euroglyphus maynei (Acari: Pyroglyphidae) [10, 11 ], while the stored-food mites found in houses are mostly represented by Acarus siro, Tyrophagus putrescentiae (Acari: Acaridae), and Glycyphagus domesticus (Acari: Glycyphagidae) [ 12]. All these mites display particular relationships with xerophilic fungi. In this deliberately interpretative review I will try to outline the advances in knowledge that have been made concerning these ecological relationships in the domestic environment. Because so many mites are known and a lot of the species may be considered as domestic mites, to narrow the field particular attention is paid to D. pteronyssinus and D. farinae for house-dust mites and A. siro and T putrescentiae for stored-food


The work concerns the theory of adaptive control. By using available tools of contemporarymathematics as well as computer science it is possible in the credible way to introduce the laws ofcontrol of a dynamic system as well as to simulate such process in the real world. Therefore wecan learn the working of system by simulation, i.e. we can get precise knowledge about theparameters of the system, which were unknown at the beginning of the control process.


Historically, the rivers of Quebec have played outstanding parts in the territory cultural and political establishment, in the homeland discovery and colonization processes, and also in its economic development. One after another, transportation, trade, log driving and hydroelectricity production have been the dominant usage on these watercourses, and any other users had to give in. For the last thirty years, the wastewater cleaning efforts, the watercourse public access development as well as the withdrawal on some pollution producing practices like log driving, have given rise to a new recreational usage on rnany of these watercourses. In reality, this recreational usage barely put up with the magnitude of the hydro electricity production. This resuits in conflicts with increasing rate and intensity. The recreational users' demands are taken in consideration by the hydro electricity projects participants. However this consideration doesn't seem to satisfy the recreational users' expectations due to fundamental opposed viewpoints and principles which are being promoted by each group. Such radical divergence between these two groups introduces the notion of strategy being promoted by one group to be able to pressure the other group's practices. These strategies development depends on the participants' ability to force social issues upon the others pressing them to reconsider their own underlying principles. In the case of the conflict opposing the recreational whitewater industry with the small private hydroelectric projects on the Gatineau River, the recreational users, with the use of recontextualisation (or reframing of information) processes have been able to slow down and even momentarily stop hydro electric projects there. These recontextualisation processes are based on landscape related social representations which emphasize the aesthetic, emblematic and identity dimensions of the Gatineau River. These social


The conceptual phase of structural design involves selecting preliminary materials, selecting the overall structural form of the building, producing a rough dimensional layout, and considering technological possibilities. Decisions are made on the basis of such information as height of the building, building use, typical live load, wind velocity, earthquake loading, design fundamental period, design acceleration, maximum lateral deflection, spans, story height, and other client requirements. More detailed information about the task itself, constraints, possible solution principles, and known solutions for similar problems is extremely useful in the process of defining and finding a solution to the design problem. This paper presents the M-RAM, which is intended to assist engineers in the conceptual phase of the structural design of tall buildings by providing designers with adapted past design solutions generated by a distributed multi-reasoning mechanism. The objective of the M-RAM (Multi-Reasoning Model...

SrZrO3/SrTiO3 (SZO/STO) artificial superlattices were fabricated on STO substrates by the molecular beam epitaxy. The structures of the superlattices were analyzed by reflection high-energy electron diffraction, normal θ-2θ scan mode X-ray diffraction analyses and reciprocal space mapping measurement. Their lattice parameters showed that the lattice distortion is dependent on stacking periodicity and is maximum in the [(SZO)10/(STO)10]4 superlattice. The dielectric properties were measured using interdigital electrodes at frequencies up to 110 MHz, and dielectric relaxation was observed in the [(SZO)1/(STO)1]40 and [(SZO)10/(STO)10]4 superlattices in the low-frequency domain. The dielectric permittivities of all superlattices with interdigital electrodes were more than 10,000 at 110 MHz. The charge vs voltage (Q-V) measurement revealed that the SZO/STO superlattices show distinct hysteresis curves, which indicated that ferroelectricity is induced by the superlattices. The origin of the ferroelectricity seems to be related to the anisotropic lattice distortion incorporated into the superlattice structure.


The Improving America's Schools ACT (IASA) emphasizes coherent systemic education reform, with Goals 2000 setting common standards for IASA and the recently authorized School-to-Work Program. IASA addresses the need to raise academic achievement, increase opportunities to learn, improve professional development, increase community involvement, utilize instructional applications of technology, and improve assessment, and allow more local flexibility in the use of funds.


Abstract : The instrumentation developed provides unique tools for the study of stability of underground openings particularly where deformation measurements are required very close to a drilled or blasted opening and where extended periods of automatic data recording are needed. The Laser System employs a coarse and fine raster scanning concept to measure relative motion of passive targets. The course scan locates a target within a 1-in. square (approximate) field of view; the fine scan locates the target's position within the 1-in. square. The concept, in theory, should have very good accuracy and repeatability but depends upon the capabilities of the instrument components. Details of the concept are contained in Appendix B.

The solar magnetic field drives a wide range of phenomena, from sunspots to flares and coronal mass ejections. This field is maintained against ohmic dissipation by means of a hydromagnetic dynamo. In recent years, evidence has accumulated in support of a particular family of dynamo models, Babcock-Leighton models, where the surface fields play a key role. Specifically, the surface transport of magnetic flux coming from emerged regions regenerates the global dipole field, which is the source of the subsurface toroidal field for the next cycle.

Many global dynamo models rely on the approximation of axial symmetry. In this thesis, we explore the consequences of relaxing this assumption. Relaxing it on the the surface, we find that the large-scale converging flows around active regions affect the strength of the global dipole. This may contribute to the variability of the solar cycle and provides a saturation mechanism. Relaxing the assumption beneath the surface, we find that the subsurface azimuthal field of the Sun is strongly axisymmetric.


The performance of optimum minefield detection tests for unpatterned minefields is determined in this paper. A replacement model for an unpatterned (scatterable) minefield is defined. The log-likelihood ratio for minefield detection is then derived from the model, and detection performance (receiver operating characteristics) determined. The model is validated by a comparison with empirical results for data acquired with the Marine Corps Coastal Battlefield Reconnaissance and Analysis (COBRA) passive multispectral electro-optical sensor. Work with data from the US Army Remote Minefield Detection System (REMIDS) program is also discussed. The replacement model is extended to model the effect of clutter on minefield detection performance; clutter has a substantial impact on performance. Several issues for minefield detection are discussed in detail. First, the notion of jointly sufficient statistics for unpatterned minefield detection is defined. This leads to the categorization of previous work in minefield detection into hard decision and soft decision techniques. The soft decision technique is based on the idea of aggregating individual mine likelihoods over a candidate minefield region, as opposed to hard thresholding the individual mine calls and using the density of detected mines to determine the presence or absence of a minefield. The performance analysis is based on an application of the Central Limit Theorem; these results are validated by simulation, and in a particular case, by an exact computation of the relevant false alarm probabilities.


This screening population investigation for hyperkinetic disorders (i.e. attention-deficit hyperactivity disorder – ADHD) was a part of prospective clinical investigation 'The System of Differentiated Integral Medico-social Rehabilitation of Hyperkinetic Disorders in Children' initiated by the Ministry of Health of Belarus. The aim of this investigation was to explore gender differences, the ADHD structure, clinical dynamics and social maladjustment factors. Material: 1846 children 3 to 15 years old, all attending kindergartens or primary and secondary school, 947 boys and 899 girls. Clinical assessment involved use of the VADTRS psychometric scale (Vanderbilt ADHD Diagnostic Teacher Rating Scale). The results suggest presence of ADHD in 6,2% Belorussian children aged 3 to15 years: in 9,3% of boys and in 2,9% of girls. The ADHD prevalence is significantly higher (3,2 times) in boys in comparison with girls. In girls, diagnostic thresholds for attention problems and impulsive behavior happen to be significantly lower than in boys. Mixed ADHD forms appear to prevail in boys, while specifically attention disorder is more common in girls. The hyperactivity symptoms in Belorussian boys and girls seem to decrease by 9-11 years of age, though the puber girls are more prone in this period to oppositional behavior due to increased impulsiveness. Attention disorder has been identified as the principal clinical factor underlying social maladjustment, both in boys and girls, and for that reason mixed forms of ADHD and attention deficit disorder (ADD) have a higher risk potential for social maladjustment than hyperkinetic forms.

The coupled cluster method is implemented at high orders of approximation to investigate the zero-temperature (T = 0) phase diagram of the frustrated spin-s J1-J2-J3 antiferromagnet on the honeycomb lattice. The system has isotropic Heisenberg interactions of strength J1 > 0, J2 > 0 and J3 > 0 between nearest-neighbour, next-nearest-neighbour and next-next-nearest-neighbour pairs of spins, respectively. We study it in the case J3 = J2 ≡ κJ1, in the window 0 ≤ κ ≤ 1 that contains the classical tricritical point (at κcl=12) of maximal frustration, appropriate to the limiting value s → ∞ of the spin quantum number. We present results for the magnetic order parameter M, the triplet spin gap Δ, the spin stiffness ρs and the zero-field transverse magnetic susceptibility χ for the two collinear quasiclassical antiferromagnetic (AFM) phases with Néel and striped order, respectively. Results for M and Δ are given for the three cases s=12, s = 1 and s=32, while those for ρs and χ are given for the two cases s=12 and s = 1. On the basis of all these results we find that the spin-12 and spin-1 models both have an intermediate paramagnetic phase, with no discernible magnetic long-range order, between the two AFM phases in their T = 0 phase diagrams, while for s > 1 there is a direct transition between them. Accurate values are found for all of the associated quantum critical points. While the results also provide strong evidence for the intermediate phase being gapped for the case s=12, they are less conclusive for the case s = 1. On balance however, at least the transition in the latter case at the striped phase boundary seems to be to a gapped intermediate state.


Readers who have grown somewhat long in the tooth may recall a time when scholarly pursuits that affected both learners and their instructors were vastly different from what exists today. It was not so long ago that a benighted student who either missed a lecture or who perhaps was fortunate enough to doze off midway through it could rely on the beneficence of a note-taking classmate to share the intellectual fruits that were dispensed on that occasion. Prior to the availability of copy machines in libraries, the notes had to be transcribed by hand, but the alternative of not having any record of the classroom proceedings was unappealing. Another common activity heretofore experienced was to be assigned an article from a periodical that was placed in the reserve section of the campus library. Oftentimes, the said object of desire was being used by another reader. When that occurred, the only choice was to have one's name added to a list that specified the exact time at which the paper would become available to peruse for one or two hours. If the article was of recent vintage such as in the latest issue of the journal, some lag time still could be involved. From the date the periodical was printed, mailed, catalogued in the library, and considered worthy of being assigned by a professor, several months could have elapsed. It became the responsibility of students to digest what at first glance might appear to be indigestible and then be able to play back its essential contents in the form of answering an exam question or citing them in a paper that had to be submitted as a requirement for passing the course. Instructors were faced with other kinds of impediments. When preparing their own articles, they had to scour the available literature in the campus library to discover useful citations from a wide range of periodicals. If fortunate, perhaps some of these items contained an annual index. Otherwise, they had to thumb through the table of contents volume by volume. Another challenge was to have library personnel request to borrow material found only in another institution's library. While resources such as Index Medicus were extremely valuable in those days, there still was value in searching for gems that might have missed inclusion in such compendia. Fast forward to the year 2011 and it is easy to see how enormously different is the world of scholarly pursuits. From the perspective of students, while reclining on a sofa they can download lectures, access journal articles at the click of a keyboard, and direct queries to faculty and fellow students by e-mail and text messages. …


The dependence of the bulk viscosity with the relativistic parameter z = kT/mc 2, obtained through the complete Boltzmann equation [1, 2], is thoroughly analyzed. A complete and rigorous examination of the relevant non-relativistic and ultra-relativistic limits is carried out in the case of a hard disk model and compared with the results obtained in the relaxation time approximation. The modifications of the non-vanishing bulk viscosity to the Rayleigh - Brillouin is briefly discussed.


OBJECTIVES
To examine the difference in tobacco use between adolescents who participate in organized sports and those who do not.

METHODS
Using a cross-sectional study design, this study uses data from a nationally representative sample of adolescents enrolled in public high schools in the United States.

RESULTS
Those participating in organized sports were 25% less likely to be current cigarette smokers. However, smokeless tobacco use was found to be associated with participation in organized sports.

CONCLUSIONS
Given the large proportion of students involved in organized sports, intervening through this venue to address tobacco use has the potential to reach significant numbers of adolescents.


Aiming at the problems of how to efficiently validate the software with graphical interface and avoid tedious duplication of work to save time and reduce costs, a design method of the automation testing based on image recognition is proposed. The automation testing based on image recognition can verify the appearance of page elements and the relative positions between elements effectively and can directly support the software testing in various operating systems. In the long time continuous testing, the automation testing based on image recognition is more reliable comparing with the automation testing based on identifying the object of the software under test. What's more, it has no special requirement for testers' programming ability. The experimental results show that the proposed method of automation testing based on image recognition testing has its unique advantages in software testing, which can effectively verify the software with graphical interface, improve testers' work efficiency and save costs to accelerate the iteration of software development and version.


Our ecosystem's least transparent industry is real estate.Housing prices fluctuate on a daily basis and are sometimes hyped rather than based on valuation. Our research project's main focus is on predicting housing prices using real-world factors. Our goal is to make evaluations on each and every basic parameter that is properly considered when determining the price. We used multiple linear regression to estimate house prices based on square footage and the number of bedrooms in this paper. The relationship between the mean value of one variable and the values of other variables is measured by regression.Regression analysis is a collection of statistical for calculating theassociation between multivariate in statistical modelling.Multiple variables Explain the association between one uninterrupted Basedon variable (y) and two or more individualistic variables. linear regression (x1, x2,x3...etc). Three modules were used to implement this: The data entry module is used to provide the project with the information when it requires. The Analysis module is used to examine and forecast house prices based on the needs of the customer. The Front-end module is used to create the project's required GUI screens.

I.INTRODUCTION In this era of globalization, investment is a business activity that most people are interested in. Gold, stocks, and real estate are just a few examples of commonly usedinvestment objects. Property investment, in particular, has increased significantly. Housing price trends are not only a source of concern for buyers and sellers, but they also reveal the state of the economy. House cost are impact by a variety of point, plus the number of sleeping chamber and shower room. The nearby location, which has excellent access It also leads to roads,superhighway, schools,marketplace, and localduty, opportunities. the increase in house price. Manual house prediction becomes difficult, so many systems for house price prediction have been developed. Accurately predicting house prices has always attracted the interestinboth purchaser and vendor, as well as broker dealercapitalist croupierhouse tellertreasurer usurerbanking executive. Many scholars havealready attempted to decipher the enigmas of house price forecasting.House price prediction is a classic problem that has been extensively studied using machine learning tools and techniques.Many theories have emerged as a result of thecontributions of various researchers from around the world.Some ofthese theories suggest that the geographical position and culture of a given region decide how home prices will rise International Journal of Scientific Research in Engineering and Management (IJSREM) Volume: 05 Issue: 05 | May 2021 ISSN: 2582-3930 © 2021, IJSREM | www.ijsrem.com Page 2 or fall, whereas others believe that socioeconomic factors are a major factor in increasing home prices.We all recognize that house worth may be a variety from some outlined assortment, thus clearly the process of forecast the price of a house is a regression task. An individual can forecast the cost of a house by using the following formula will typically look for similar properties in his or herneighborhood and then attempt to predict the price based on the information gathered.All of this suggests that The field of regression research into home price forecasting is a pretty modern one that necessitates machine learning expertise. This has sparked my interest in working in this field. Researchers are faced with two major challenges. The most difficult task is determining the area of regression research into.Home price forecasting is a relatively new concept. Housing price growth is determined by various residential construction sectors.Kahn's model illustrates the impact that house prices can havean essentiallyHome wealth grows faster than wages, giving it a trendy look for a long time before collapsing and experiencinga long period of decline. The researchers' second major challenge is to determine whichIn terms of accurately forecasting house prices, machine learning would be the most popular tool.Ng and Deisenro develop a smart phone framework for Gaussian process regression. To develop precise mathematical models for forecasting housing prices.Hu et al use the maximum information coefficient (MIC). However, we now recommend using multi variate regression because it is more accurate and highlights some key attributes.


An uncertainty analysis methodology is proposed to aid in quantifying the risks of thermal comfort under-performance posed by changes to variations in physical and operational characteristics of a building and its environment. This includes those implemented for building energy savings, peak electricity load reductions, or those due to climatic changes. Using building performance data as input, a response surface methodology is used to develop a model to predict building thermal performance for ranges of user-defined design variables. This model is verified for accuracy using in- and out-of-sample data. Uncertainly analysis is then used to estimate the probability of achieving an acceptable threshold of thermal comfort performance. A case study is presented to demonstrate the implementation and interpretation of the results of this methodology, which evaluates the effects of a 1-h demand response event on thermal comfort of a residential mechanically-conditioned building. The case study finds that a second-order response surface provides a reasonably accurate model of thermal comfort. For the studied single family home, compared to varying the air exchange rate, the indoor set-point temperature has a greater influence on achieving an acceptable level of thermal comfort.


This chapter discusses how workforce development initiatives vary widely across governments and institutions, and how institutional research can help bridge the gaps between them.


This paper presents the optimization of a compact electro-explosive fuse designed for the power conditioning system to be driven by a helical flux compression generator (HFCG). An electro-explosive fuse interrupts the current flow from the HFCG through a storage inductor on a 50 to 100 ns timescale inducing a voltage large enough to close a peaking gap, which commutates the energy in the storage inductor into a 20 Ohm load at voltage levels above 200 kV. Experimental data has revealed that electro-explosive fuses with wires in closer proximity to one another have consistently produced lower pulsed voltages than fuses with larger wire spacings. This paper addresses possible factors that might contribute to this drop in performance. An electro-magnetic field solver is used to model the current redistribution in the fuse wires. The experimentally observed performance of compact fuses with varying wire spacings is presented.


Three major lithofacies have been described in Lajjun area, central Jordan, including the phosphorite and intercalated limestone of the Al‐Hisa Phosphorite Formation, as well as the Muwaqqar Chalk Marl Formation. 87Sr/86Sr isotopic data indicate a late Campanian age for the Al‐Hisa Phosphorite Formation, whereas the overlying chalk of the Muwaqqar Formation contains the lowest Maastrichtian planktic foraminiferal zone of Rugoglobigerina hexacamerata (CF8b).


Standard calculational models of plate-type LMFBR critical assemblies do not explicitly represent individual plates. Instead, detailed plate-by-plate calculations are performed only for each representative cell type, and homogenized cross sections are defined by flux-volume weighting of individual plate cross sections. Subsequent reactor calculations are performed by modeling each cell type with homogenized cross sections. The homogenized cross sections are sensitive to the manner in which the cell leakage is modeled. The intent of this paper is to present a method of representing the cell leakage which results in more accurate homogenized cross sections than the methods presently in use.


In this paper, we study the potential of terrestrial 3D HDTV (High Definition Television) broadcasting by a modification and an extension of the ATSC 8-VSB transmission system. First, we analyze the performance and the limit of conventional ATSC (Advanced Television Systems Committee) 8-VSB (Vestigial Side Band) transmission system. By referencing the performance of ATSC systems, we examine the possibility of the transmission capacity increase at a reasonable TOV (Threshold of Visibility) by employing powerful LDPC (Low Density Parity Check) & BCH (Bose Chaudhuri Hocquenghem) codes instead of conventional RS (Reed Solomon) & TCM (Trellis Coded Modulation) codes, varying the code-rates, and increasing the modulation constellation. We do not consider the complete backward compatibility for the maximum transmission capacity increase, as in the DVB-T2 system.


Transition metal dichalcogenides (TMDs), i.e. MoS 2 and WS 2 , are fascinating materials due to their optical, electronic and catalytic properties. Monolayers of semiconducting TMDs possess a direct band gap and large optical absorption [1,2] ideal for constructing novel optical and electronic devices. In addition, MoS2 and WS2 have a high catalytic activity, and a wide range of physiochemical properties [3,4]. Such applications arise from the scalable synthesis of atomically thin TMD sheets via chemical vapor deposition (CVD). Grain boundaries (GB) and dislocations are inevitable defects in 2D layered crystals synthesized by the CVD [5]. Therefore, it is important to image and probe defects and their atomic and chemical structure before they can be nano-engineered. Because of the unique three-atomic thickness in monolayers of TMDs, defects behave very differently from those observed in 2D monatomic films (i.e. graphene). In addition, this sandwich structure can lead to unique dislocations and different grain boundary structures and dynamics. We use ultra-high resolution aberration-corrected electron microscope (TEAMI) with sub-Ångstrom resolution in order to understand the atomic structure of GB and dislocations in WS 2 monolayers. Annular dark field (ADF) STEM images of GB in WS 2 show the atomic structure of the CVD-grown films [6]. The material contains monolayer, bilayer and trilayer


Reasons for the consumption of mercuric chloride catalyst in the production of PVC by calcium carbide method were analyzed as well as its distribution.The results showed that the water content of mixed gas beyond limit was the main reason for the consumption of mercuric chloride catalyst,and the amount of consumed mercuric chloride accounted for 77.55% of the total amount of mercuric chloride.


The invention discloses a bed with a bedpan. A bed body, a bedpan support rod, a first connecting rod and a second connecting rod compose a parallelogrammic connecting rod mechanism; and one of the first connecting rod and the second connecting rod is fixed with a door for closing an excrement opening. Thus, in the process of driving the parallelogrammic linkage through a driving mechanism, the door can rotate in company. Specifically, during parallelogrammic linkage, the door is opened, and the mouth of a bedpan supported on the bedpan support rod can be arranged right opposite to the excrement opening, so that a patient lying in bed can defecate into the bedpan; and after the defecation is finished, the parallelogrammic linkage drives the bedpan support rod to move, and the bedpan supported on the bedpan support rod can be moved away from the excrement opening and moved into an appropriate out-taking position, so that medical care personnel can conveniently take out the bedpan, and the excrement opening is closed by the door at this time. By using the bed with a bedpan, patients can naturally lie. Besides, the bed with a bedpan is convenient to operate, facilitates the defecation of patients and reduces the workload of medical care personnel taking care of the patients.

Deep learning has emerged as a popular Artificial Intelligence (AI) technique to make conventional cyber physical systems become intelligent and sustainable. Recently, deep learning has been widely used in the network domain. With the aid of powerful deep neural networks, the communication network can carry out packets forwarding actions intelligently to avoid possible failure and congestion. However, with the high computing cost and process limitation in only the static network scenario, the existing deep learning based network traffic control algorithms cannot satisfy the sustainable requirement of next generation large scale dynamic network. To conquer the existing problems, a novel spatial-temporal value network aided deep learning based intelligent traffic control algorithm referred as ST-DeLTA is proposed in this paper. In ST-DeLTA, the value matrix and spatial temporal training model (ST model) are employed to intelligently extract the spatial as well as temporal features of traffic patterns and make adaptive packets forwarding decision in large scale and dynamic networks. The mathematical analysis gives the computing cost reduction of our proposal, and the computer simulation demonstrates that our proposal has significantly better training and network performance compared with traditional algorithms in terms of training accuracy, transmission throughput, and average packets loss rate.


The influence of the amino group of guanine on the molecular electrostatic potential and the accessibility to reactive sites of B-DNA is investigated by comparing the two model double helices poly (dI.dC) and poly (dG.dC). The calculations clarify the "disruptive" role of the guanine amino group on nucleic acid-polypeptide interactions. INTRODUCTION Recent studies from our laboratory have demonstrated the significance of the molecular electrostatic potential, in particular when considered in parallel with the accessibility to reactive sites, for the elucidation of various aspects of the biochemical behaviour of the nucleic acids (1, 2). For B-DNA, the form of DNA considered as the most relevant under physiological conditions, these studies have brought into evidence the differences between sequences of G-C and A-T base-pairs, from the point of view of the above properties and in particular of the electrostatic potential (3, 4). Thus, studies of complete turns of the model double helices of poly (dG.dC) and poly (dA.dT) have shown that while in the former the deepest potentials are associated with the major groove, they are associated with the minor groove in the later. This result has been abundantly correlated with the reactivity of nucleic acids, synthetic polynucleotides and their constituents towards a variety of reactants involving carcinogens, mutagens, antibiotics, chemotherapeutic agents and oligoor polypeptides (5-10). In order to elucidate the role played by the structural variations between the two types of the fundamental complementary base pairs, A-T and G-C, in the origin of the differences in the molecular electrostatic potentials and the accessibilities of sequences involving these pairs we have now extended our computations to a complete helical turn of a B-DNA model of poly © IRL Pres Umited, 1 Falconberg Court, London W1V 5FG, U.K. Volume 9 Number 24 1981 7041 Nucleic Acids Research Nucleic Acids Research (dI.dC) which differs from poLy (dG.dC) by the replacement of guanine by hypoxanthine (thus of guanosine by inosine). Hypoxanthine (inosine) differs from guanine (guanosine) by the absence of the 2-NH2 group and as a result of this situation the I-C pairs contain only two hydrogen bonds, as do the A-T pairs. This investigation should thus bring straightforward information on the effect on the potential and the accessibility of B-DNA of the suppression of the third H-bond of the G-C pair, through the elimination of the guanine amino group. It should also throw light on the consequent modifications of biochemical reactivity. METHOD The model polynucleotides studied were in the B-DNA double helical conformation with the geometry due to Arnott and Hukins (11). A full turn of the helix was considered. Poly (dI.dC) was constructed from poly (dG.dC) simply by replacing guanine by hypoxanthine, the latter base having the same geometry as guanine with the exception of the replacement of the C2-NH2 bond by a C2-H bond with the standard length of 1.08 A. The calculation of the molecular electrostatic potentials of these polynucleotides was performed as described in our previous publications (1, 2). The overall potential of the polymer was obtained as a superposition of the potentials of its subunits, the bases, sugars and phosphates. The potentials of these subunits were computed from multipole expansions of their electron density, derived from ab initio wavefunctions. This procedure has been shown to lead to a satisfactory reproduction of the electrostatic potential of the subunits down to a distance of 2 A from their constituent atoms. Below this distance exact potentials were evaluated. In the forthcoming discussion we shall use two representations of the results obtained. The first pertains to the potential minima associated with the most important nucleophilic sites on the bases (1, 2, 5). The second refers to surface envelopes surrounding the polynucleotides (2, 4, 12). These envelopes are formed by the intersection of spheres, centered on each atom of the macromolecule, with radii proportional to the van der Waals atomic radius (a proportionality factor of 1.7 was used here, as in our preceeding studies (2, 4)).The advantage of these envelopes is to give a clear view of the potential distribution over a large surface of the macromolecule and they are thus particularly useful in interpreting its interaction with other large molecular species, such as e.g. polyamines, oligo and polypeptides etc...


Attacks by (jihadi) terrorists have become more frequent over the past decade. As the neighbouring countries experienced more frequent and more deadly terrorist attacks (see Figure 1), the Dutch authorities grew increasingly concerned about the possibility of similar attacks happening in the Netherlands. In particular, the threat of Dutch (jihadi) terrorists acquiring heavy firearms to conduct Bataclan-like attacks loomed in the back of policymakers' minds. Preventing such heavy firearms from falling into the wrong hands became a top policy priority. In 2016, this led the Dutch Ministry of Justice and Security to commission a study on how firearms are acquired by terrorists, specifically


Terraforming is the process of transforming the present climate of Mars into a more Earth-like environment for the future human settlement of the planet. Although implementing such a project appears infeasible in the near-term, writers of speculative fiction (SF) have envisioned what it might be like since the beginning of the 20 th Century. One of the first portrayals of terraforming was in the 1917 novel A Princess of Mars by Edgar Rice Burroughs, who wrote of an "atmosphere factory" that made the arid world he called Barsoom habitable. From the post-World War II period to the present day, terraforming continues to be a popular topic in SF. This paper will survey some of the major works of terraforming fiction, including The Sands of Mars (1952) by Arthur C. Clarke, Man Plus (1976) and Mars Plus (1994) by Frederik Pohl, Moving Mars (1993) by Greg Bear, Mining the Oort (1992) by Frederik Pohl, the Red Mars/Green Mars/Blue Mars (1993-96) trilogy by Kim Stanley Robinson, and White Mars (2000) by Brian Aldiss.


While it is probable that Common kingfishers Alcedo atthis used to be found in central Tokyo, they have for long been found only in the outskirts of the city. However, recently they have appeared in many locations near the center of the city. We observed their breeding at the Akasaka Imperial Grounds in the center of Tokyo. In the first brood, four young were observed to fledge on May 20, and in the second, five young fledglings were confirmed on July 14 and 15. Some aspects of breeding behaviour of the parents are described.


The buckling load capacity of a form of cellular-walled circular cylindrical shell suggested by fossil shell remains is analyzed. Shells under combined loading of axial compression and external pressure are studied. In particular, the effect of high fluid pressure within the cells on the buckling behaviour of the shell is considered. This study demonstrates that shells of this type with pressurized cells exhibit significantly improved stability and thus appear to have potential in engineering applications, particularly in marine situations.


Values of electrical conductivity, K, and apparent activation energy of conductivity, E K , of molten slags of the copper industry as function of temperature and composition of slags were determined. Electrical conductivity values of molten investigated slags increase with the increasing temperature and vary from 0.25 to 30 Sm -l . Electrical conductivity values rise with increasing of copper (I) oxide concentration in molten slags from the flash smelting copper concentrates and decrease with the increasing of silica concentration in the blast furnace slags. The original industrial slags are multicomponent mixtures. However, it did not succeed to determine of the effect of the concentration of the individual components on the electrical conductivity values these slags. Electrical conductance data were analysed in terms of the three parameter equation: K =AT -1/2 exp[-B/(T- T o )]. The apparent activation energy of electrical conductivity values determined for molten industrial slags are 100-260 kJ/mol at 1500 K. The activation energy values decrease as the temperature increases. Variations of energy activation values with temperature may result from structural changes occurring in molten silicates. This is because the degree of polymerization of the silicate anions decreases with the increasing temperature. The mechanism of conduction in investigated industrial slags is considered to be ionic (mainly cationic). This is because the conductivity of these melts is of the same order as that of molten salts and the order of magnitude of the apparent energy of activation is typical for ionic conduction.


Kotelevskaya V.V. Keywords : novel, modernism, postmodernism, narrative discours, ethos of the leisure The article proposes to introduce a number of key modernist and postmodernist novels through specific social, cultural, and economic backgrounds. The question of leisure ethos assumes greater significance in light of the longing for the past in the new era of speed, production and consumption. The author traces the mutations of the novel in the twentieth century with reference to social and historical sources and sufficient reworking of the leisure idea by authors with very different beliefs and backgrounds (M. Proust, H. Hesse, F. Beigbeder, P. Handke, E. Jelinek, etc.).


Abstract In many countries, population ageing is challenging the viability of the welfare state and generating higher demands for long-term care. At the same time, increasing participation in the labour force is essential to ensuring the sustainability of the welfare state. To address the latter issue, affected countries have adopted measures to increase employment; e.g. welfare recipients in Germany are required to be available for any type of legal work. However, 7 per cent of welfare benefit recipients in Germany provide long-term care for relatives or friends, and this care-giving may interfere with their job search efforts and decrease their employment opportunities. Our paper provides evidence of the relationship between the care responsibilities and employment chances of welfare recipients in Germany. Our analyses are based on survey data obtained from the panel study 'Labour Market and Social Security' and on panel regression methods. The results reveal a negative relationship between intensive care-giving (ten or more hours per week) and employment for male and female welfare recipients. However, employment prospects recover when care duties end and are subsequently no longer lower for carers than for non-carers.


395Background: Telotristat ethyl (TE) is approved to treat inadequately controlled carcinoid syndrome (CS) diarrhea in combination with somatostatin analog (SSA) therapy. Understanding the time to onset of sustained BM frequency improvement is important when considering the use of TE in patients with CS diarrhea. We present data on time to sustained improvement and worsening in BM frequency during the double-blind treatment (DBT) period of TELECAST, a phase 3, randomized, placebo-controlled, double-blind study in patients with CS that required additional treatment, primarily due to gastrointestinal symptoms. Methods: Stable dose SSA was not required. Patients were treated with TE 250 mg 3 times per day (tid), TE 500 mg tid, or placebo tid. Sustained response was defined as the time from the first double-blind dose date to the first day of 2 consecutive weeks with BM frequency change of at least 30% from baseline. The time to the first sustained response in the TELECAST study was examined among treatment g...

The effect of chemical reaction on laminar mixed convection flow and heat and mass transfer along a vertical unsteady stretching sheet is investigated, in the presence of heat generation/absorption with variable viscosity and viscous dissipation. The governing non-linear partial differential equations are reduced to ordinary differential equations using similarity transformation and solved numerically using the fourth order Runge-Kutta method along with shooting technique. The effects of various flow parameters on the velocity, temperature and concentration distributions are analyzed and presented graphically. Skin-friction coefficient, Nusselt number and Sherwood number are derived at the sheet. It is observed that the influence of chemical reaction, the fluid flow along the sheet accelerate with increase of chemical reaction parameter, on the other hand, temperature of the fluid increases with increase of chemical reaction parameter but concentration of the fluid reduces with it. The boundary layer decreases on the surface of the sheet for all values of unsteadiness parameter, increasing values of the chemical reaction parameter. The increases in the values of Sc cause the species concentration and its boundary layer thickness to decrease resulting in less induced flow and higher fluid temperatures. This is depicted in the decreases in the velocity and species concentration and increases in the fluid temperature as Sc increases


Fetomaternal hemorrhage (FMH) is a poorly understood condition in which there is a transfer of fetal blood to the maternal circulation. It occurs in approximately 1-3 per 1,000 births. We described five cases with characteristics suggestive of both acute and chronic anemia. When FMH is suspected, maternal blood can be checked for the presence of fetal red blood cells and usually there are three diagnostic modalities: Kleihauer-Betke test, flow cytometry and Rosette test. The clinical manifestations and the prognosis of FMH depend on the gestational age, the volume of the hemorrhage and the rapidity with which it has occurred. Red blood transfusion is recommended, while in case with severe anemia and cardiac failure an exchange transfusion can be considered. The physician's awareness of the condition, the ability to suspect and diagnose it with appropriate testing have a significant impact on the epidemiology, accurate management and prognosis for the anemic neonates.

Nowadays the mathematical simulations of the real-world problems can be and are expected to be very accurate. The mathematical models used for such simulations must be therefore of the appropriate complexity. On the other hand the number of degrees of freedom and related number of the equations of the model must be preserved on the fairly low level, insuring the acceptable processing times which are, of course, different for different purposes of the simulations. In the paper the basic and the enhanced mathematical models of a slewing crane during slewing motion are presented and the development of the enhanced model from the basic model is described including the procedure of reduction of the degrees of freedom. The results of the simulations and of the measurements are compared and in the case of the enhanced mathematical model an obvious improvement of the agreement is estimated.


Genetic algorithms are an efficient mechanism to generate unit tests. Automatically generated unit tests are known to be an important asset to identify software defects and define oracles. However, configuring the test generation is a tedious activity for a practitioner due to the inherent difficulty to adequately tuning the generation process.This paper presents TestEvoViz, a visual technique to introspect the generation of unit tests using genetic algorithms. TestEvoViz offers the practitioners a visual support to expose some of the decisions made by the test generation. A number of case studies are presented to illustrate the expressiveness of TestEvoViz to understand the effect of the algorithm configuration.Artifact – https://github.com/andreina-covi/ArtifactSSG

Summary from only given. We have observed transition and pure bend loss in holey fibers and have shown the relative contributions to be dependent on the angular orientation of the bend. A simple model is developed that preserves the exact refractive index profile and so can be used to model the bend loss in any microstructured fiber.


The Silk Road gained a good reputation and unprecedented fame, as a result of the goods known for its name, which was not only attracted the attention of merchants and travelers, but was the focus of attention of the caliphs, kings and kingdoms through which the convoys of multinational merchants were passing as it was not only a route for silk merchants, but was The Silk Road also played an important role in scientific and economic exchanges. Therefore, the Silk Road is not merely a geography, not a history, not merely an identity. This identity is united by difference, convergence and contrast. Coexistence and peace


As each university owns several web sites dedicated to face-to-face lectures support or distance learning training, courses can no more be considered as global presentations of theory elements. Organizations involving different actors, contribute to produce documents and information and doing so must share knowledge. We present in this paper a way to index documents inside a memory adapted to e-learning situations. This indexing mainly requires concepts representing the pedagogical notions of the domain of training. It requires also some concepts that are typical of learning activities.

What can be done to resolve the seemingly endless conflict in Sudan ? A nation of 36 million people, wracked by conflict for 34 of the last 45 years, it has generated some 4 million displaced people during the course of its war. It is estimated that over two million Sudanese people have died as a result of fighting and related starvation and disease. According to the International Crisis Group, "there will always be abundant excuses to justify the continuing war in Sudan...However such justifications sound increasingly hollow in the face of decades of suffering...The time has come for a concerted international peace effort to break the logjam of violence in Sudan". Indeed, this moment in time, amidst the reordering of global relations in the so-called War on Terror and Sudan's historical harboring of its suspected architect, Osama Bin Laden, has created an opening for peacebuilding. The oil factor has assumed critical importance as of late, and as such has been unpacked here. Our analysis suggests that revenues from petroleum production are financing the conflict, that the oilfields have become strategic targets for rebels, and that various foreign interests – China and Malaysia, and multinational corporations from Europe, North America and Asia – have interests that are not necessarily aligned with the promotion of peace. Noting that unregulated environmental and social aspects of oil production also have significant impacts on the conflict dynamic in the country, it stresses that if the international community were sincere in seeking peace for Sudan, it would take multilateral measures to regulate petro-revenues in the region. 1 ICG God, Oil and Country: Changing the Logic of War in Sudan.
