We introduce $\Delta$-groups and show how they fit in the context of lattice field theory. To a manifold $M$ we associate a $\Delta$-group $\Gamma(M)$. We define the symmetric cohomology $HS^n(G,A)$ of a group $G$ with coefficients in a $G$-module $A$. The $\Delta$-group $\Gamma(M)$ is determined by the action of $\pi_1(M)$ on $\pi_2(M)$ and an element of $HS^3(\pi_1(M),\pi_2(M))$.


Heat loss which occured because heat transfer from high temperature to low temperature is one of major problem in piping design in geothermal. Insulation used to solve the problem. These analysis carried out in 18 inch pipeline in steam field. Calcium silicate, rockwool, and foam glass is selected as 3 materials in these study. These 3 materials have different thermal conductivity, so ability to withstand heat for each of them is different. This research used to determine the best material to solve heat loss. Rockwool is the best material from the other 2


Dipeptides (DP), namely valyl–glycine (Val–Gly), alanyl–proline (Ala–Pro), and valyl–proline (Val–Pro) were synthesized by classical solution phase methods and characterized. The kinetics of oxidation of amino acids (AA) and DP by N-bromosuccinimide (NBS) was studied in the presence of perchlorate ions in acidic medium at 28°C. The reaction was followed spectrophotometrically at λmax = 240 nm. The reactions follow identical kinetics, being first order each in [NBS], [AA], and [DP]. No effect on [H+], reduction product [succinimide], and ionic strength was observed. Effects of varying dielectric constant of the medium and addition of anions such as chloride and perchlorate were studied. Activation parameters have been computed. The oxidation products of the reaction were isolated and characterized. The proposed mechanism is consistent with the experimental results. An apparent correlation was noted between the rate of oxidation of AA and DP. © 2006 Wiley Periodicals, Inc. Int J Chem Kinet 38: 376–385, 2006


This study aims to determine the influence of personality, attitude, motivation, and environment on the entrepreneurial spirit both partially and simultaneously. The research method uses a survey with 39 teachers of school cooperatives and respondents numbering 33 people. Primary data was obtained using questionnaires supported by observations and interviews on cooperative teachers and related parties: data analysis using descriptive statistics and multiple regressions with t-test and F tests. The results showed that personality, attitude, motivation, and the environment simultaneously and partially influenced positively and significantly the entrepreneurial spirit. The four variables contributed to the entrepreneurial spirit by 80.30%, while factors outside the research influenced 19.70%. The environment is the variable that contributes the most to the entrepreneurial spirit with a percentage of 23.52%, followed by personality by 20.91%, motivation 19.88%, and attitude 15.99%.


The article aims to explore the idea of school as schole in a natural environment. In this perspective, 'open school' can become a place where to experience waiting time, relationship, freedom and responsibility, in a combination and contamination of events and actions peculiar to lifelong learning. Through the promotion of the embodiment cognition and the development of "open-air" learning experience, school/schole could prove to be a priviledge way towards an integral education.

The present invention relates to a large-angle, continuous and high-resolution beam deflection scanning device based on a liquid crystal optical phased array and a scanning method, relating to the technical field of crossing of liquid crystal optics, applied optics and diffractive optics and solving the problem of the prior art that only small-angle beam deflection scanning can be realized. An angle resolution can reach the diffraction limit or higher while large-angle beam deflection scanning is achieved. The large-angle beam deflection scanning is achieved through a liquid crystal lens or aliquid crystal lens array formed with a lens layer or a lens array layer and two liquid crystal optical phased array layers. A blazed grating phase is added on the liquid crystal optical phased arrayfor beam emergence to realize continuous beam deflection scanning. Finally, the large-angle and continuous beam deflection scanning can be achieved. The device and the method have significant prospects of application in free-space optical communication, laser radars, optical tweezers, laser direct writing, optical interconnection, projection display, optical information storage and other fields.


In CLL, subsets of patients carrying stereotyped B cell receptors (BcR) share similar biological and clinical features independently of IGHV gene somatic hypermutation status. Although the chromatin landscape of CLL as a whole has been recently characterized, it remains largely unexplored in stereotyped cases. Here, we analyzed the active chromatin regulatory landscape of 3 major CLL stereotyped subsets associated with clinical aggressiveness.
 We performed chromatin-immunoprecipitation followed by sequencing (ChIP-Seq) with an antibody for the H3K27ac histone mark in sorted CLL cells from 19 cases, including clinically aggressive subsets #1 (clan I genes/IGKV(D)1-39, IG-unmutated CLL (U-CLL)(n=3)], #2 [IGHV3-21/IGLV3-21, IG-mutated CLL (M-CLL)(n=3)] and #8 [IGHV4-39/IGKV1(D)-39, U-CLL(n=3)] which we compared to non-stereotyped CLL cases [5 M-CLL|5 U-CLL]. In addition, a series of 15 normal B cell samples from different stages of B-cell differentiation were analyzed [naive B cells from peripheral blood (n=3), tonsillar naive B cells (n=3), germinal centre (GC) B cells (n=3), memory B cells (n=3), tonsillar plasma cells (n=3)].
 Initial unsupervised principal component analysis (PCA) disclosed a distinct chromatin acetylation pattern in CLL, regardless of stereotypy status, versus normal B cells. CLL as a whole was found to be closer to naive and memory B cells rather than GC B cells and plasma cells. Detailed analysis of individual principal components (PC) revealed that PC4, which accounts for 5% of the total variability, segregated subset #8 cases and GC B cells from other CLLs and normal B cell subpopulations. Although PC4 accounts for only a small part of the total variability (5%), this suggests that subset #8 cases may share some chromatin features with proliferating GC B cells, in line with the fact that subset #8 BcR are IgG-switched.
 We also investigated whether stereotyped CLLs have different chromatin acetylation features compared to non-stereotyped CLLs matched by IGHV somatic hypermutation status and identified 878 Differential Regions (DR) in subset #8 vs. U-CLL, 84 DR in subset #1 vs. U-CLL and 66 DR in #2 compared vs. M-CLL.
 As subset #8 cases seemed to have the most distinct profile, we further characterized the detected regions. The 435 and 443 regions gaining and losing activation, respectively, mostly targeted promoters (29.5%) and regulatory elements located in introns (31%) and distal intergenic regions (21.8%). Hierarchical clustering based on the 878 DRs enabled the clear discrimination of subset #8 cases from U-CLL and normal B cells; however, it is worth noting that for several of these 878 DRs the acetylation patterns were shared between subset #8 and normal B cell subpopulations rather than subset #8 and U-CLL.
 Of note, 11/435 regions gaining activity on subset #8 were found within the gene encoding for the EBF1 transcription factor (TF); additional regions were associated with genes significant to CLL pathogenesis, e.g. TCF4 and E2F1. Moreover, 3 DRs losing activity in subset #8 were located within the CTLA4 gene and 2 DRs within the IL21R gene, which we have recently reported as hypermethylated and not expressed in subset #8.
 Next, we performed TF binding site analysis by MEME/AME suit, separately for regions gaining or losing activity, and identified significant enrichment (adj-p<0.001) on TFs such as AP-1, FOX, GATA, IRF. The regions losing activity in subset #8 showed a higher number of enriched TFs versus those gaining activity (165 vs 93 TFs), particularly displaying enrichment for many HOX family members . However, a cluster of TFs with enrichment on TF binding site analysis, such as FOXO1, FOXP1, MEF2D, PRDM1, RUNX1, RXRA, STAT6, were also located within the 878 DRs discriminating subset #8 from either U-CLL or normal B cell subpopulations.
 Taken together, subset #8 cases have a distinct chromatin acetylation signature which includes both loss and gain of active elements, shared features with proliferating GC B cells, and specific changes in chromatin activity of several genes and TFs relevant to B cell/CLL biology. These findings further underscore the concept that BcR stereotypy defines subsets of patients with consistent biological profile, while they may also be relevant to the particular clinical behavior of subset #8, known to be associated with the highest risk of Richter's transformation amongst all CLL.

When a moral panic happens, society believes that a group of people and/or their behaviour is responsible for a threat to society – without any evidentiary basis. How does the target group respond? In the video game context, gamers may fear that their pastime will be blamed for mass shootings leading to social stigma. Group members so threatened are hypothesized to react to protect their group identity. This leads to increased engagement in the activity under threat. In contrast, disasters that do not threaten the group would not affect the amount of video game play. We test these hypotheses by relating the amount of game play to incidents of mass shootings and non-shooting disasters for a large sample of individuals (N = 170,000). Incidents of mass shootings that threaten the gamer community lead to increases in game playing while incidents of other disasters unrelated to gaming divert time away from gaming.


This paper discusses the OpenAV[1] release system, a new release system with at its core a balance between release date and financial support. The release system works by creating the software, announcing it, and releasing after a waiting time. If money is donated to the project, the waiting time is reduced, which in turn results in an accelerated release. This paper details the process of the OpenAV release system, discusses it in relation to other release systems. Finally the author draws on the experience gained by OpenAV Productions.


We argue that the principal cause of sensornet deployment and development difficulty is an inability to observe a network's internal operation. We further argue that this lack of visibility is due to the activity and resource constraints enforced by limited energy. We present the Mote Network (MNet) architecture, which elevates visibility to be its dominant design principle. We propose a quantitative metric for network visibility and explain why network isolation and fairness are critical concerns. We describe the Fair Waiting Protocol (FWP), MNet's single-hop protocol and show how its fairness and isolation can improve throughput and efficiency. We present the Pull Collection Protocol as a case study in designing multihop protocols in the architecture.


The application of cognitive processing therapy (CPT) for a client with posttraumatic stress disorder secondary to past physical, psychological, and sexual abuse is presented to include presenting complaint, assessment, course of treatment, and follow-up. The usefulness of CPT with abuse survivors is discussed, focusing on CPT's combination of exposure and cognitive-behavioral techniques. The provider of care in this case was a paraprofessional working at an Air Force outpatient mental health clinic. This case study illustrates how the use of paraprofessionals to support treatment plans can result in successful outcomes. Treatment implications of the case for settings with limited professional staff and managed care settings are discussed, along with recommendations to clinicians and students.


The usual known methods for generating signals with given marginal probability and spectral properties cannot be applied to binary signals widely used in theoretical problems and communications systems. To overcome this difficulty, we first present some structural properties of power spectral densities, enabling the precise definition of the concept of spectral properties. This allows us to introduce a new method valid for symmetric binary random signals. This method uses some specific properties of filters with random impulse responses. Results of computer simulations show clearly the good performance of this method. Some extensions by using random thinning can further improve its performance.


Online learning has been mandatorily adopted in many countries due to the closure of educational institutions caused by the COVID-19 pandemic. However, antecedents of the acceptance and continuance of online learning in such a situation and their changing role over time have not been well understood. This study proposed and empirically tested a longitudinal acceptance model of online learning by integrating the technology acceptance model (TAM) with the task–technology fit (TTF). Data were collected using a three-wave longitudinal survey from 251 Chinese college students after the outbreak of the COVID-19 pandemic. The results showed that most hypothesized relationships in the proposed model were supported and remained across the three-time stages, while the effects of perceived ease of use on perceived usefulness and behavioral intention changed over time. In addition, students' perceptions at previous stages had little impact on perceptions at subsequent stages, except for perceived usefulness and behavioral intention. Our study demonstrates that the integrated model of TAM and TTF could be an effective tool to understand students' acceptance of online learning across different time stages in a mandatory setting and that longitudinal design could be applicable to examine the changing mechanism of the acceptance and continuance use of online learning over time.


The topic of product assortment has generated a plethora of research across various domains, including economics, analytical and empirical modeling, individual and group decision making, and social psychology. Despite the voluminous assortment research, however, the key findings have remained scattered across domains. In fact, the very domain of assortment research has not been clearly defined, thus complicating the understanding of the current state of assortment research. The goal of this review, therefore, is to define the field of assortment research and outline its key findings. In this context, this review delineates three key domains of assortment research: (1) how consumers perceive the variety of items in an assortment, (2) how consumers choose an item from a given assortment, and (3) how consumers choose among assortments. The key findings in each of these three areas are synthesized in the form of specific research propositions that build on the existing findings and provide guidance for further empirical investigation. By outlining the key findings in each of these three areas, this review offers an integrative framework for understanding the impact of assortment on consumer choice.


Principal component regression (PCR) and partial least squares (PLS) chemometric methods wereapplied to the simultaneous quantitative analysis of atorvastatin (ATO) and amlodipine (AML) in tabletswithout using a preliminary separation and even in presence of the overlapping spectra of the abovementioned compounds. For both PCR and PLS methods, a concentration set containing 17 differentmixtures of ATO and AML in the linear concentration range of 0.0-20.0 mg/mL for both compounds wasrandomly prepared and then the absorbance values of the concentration set were measured at the 551points-wavelength set with interval of


Ventura County Watershed Protection District (VCWPD) owns and maintains a number of debris/detention basins and dams/reservoirs that mainly serve for flood control and debris collection purposes. Most of these facilities have been developed and built jointly by the County and Federal partners like Natural Resources Conservation Service (NRCS) since the 1960s, and later delivered to the County for future Operation & Maintenance (O&M). The extent of these facilities has required development of a manual for these facilities called Debris and Detention Basin Manual. Over the years, the manual has been updated to include changes in hydrology and sediment yield among other factors. However, the manual generally does not include the history of the basins development and an O&M protocol for every basin. A dam/reservoir project that may have originally been conceived as a water supply facility (e.g., Runkle Dam in Simi Valley) and may not have met the life cycle and level of service expectations as planned due to various reasons (urban development and land use changes, large water transfer projects, etc.), has become a debris/sediment collection facility with some detention benefits by default. Over three decades after construction, the basin had collected significant sediment and consequently lost about half its storage volume due to lack of protocol for basin maintenance. The challenge is that a major portion of the basin has been filled up and vegetation has established over time that cannot be simply removed due to environmental regulation enacted in recent decades (California Environmental Quality Act, CEQA). Since the project was promoted by Ventura County Flood Control District, nowadays called VCWPD, one could not simply discount the flood reduction benefits of the facility either. The restoration of the basin to its full capacity as demanded by a public stake holder would be difficult because of stringent environmental requirements and mitigation costs to remove the vegetations, and the multitude of other stakeholders that need to be involved (environmental permits from multiple agencies, development interests, etc.). Although the basin had not been cleaned up in the early years of post dam construction, in recent years the lower portion upstream of the dam is cleaned up such that the storage for sediment and water is about half the original design. The upper parts of the basin are filled up with sediment and vegetation growth that require extensive and costly off-site mitigation if the basin is to be restored to its full capacity. Therefore, finding a scheme that would allow a multi-purpose functionality (debris collection and temporary flow detention to mitigate flooding downstream of the dam, potential water supply, off site mitigation, providing fill materials for a planned development upstream of the basin, etc.) would be a preferred approach for this facility in the future that meet all stakeholder's interests. Additionally, development of an Operation & Maintenance protocol that would be economically feasible and accepted by the stakeholders was a major goal of the project. This paper discusses the history of the basin and alternatives considered for the restoration of the basin to provide maximum flood mitigation for downstream areas.


Abstract For every prime p , we construct examples of Heineken-Mohamed p -groups whose commutator subgroup is (1) abelian with infinite exponent or (2) soluble with any prescribed derived length.


Background: Although a number of hypotheses have been proposed for keloid pathogenesis, no single unifying hypothesis adequately explains its formation. For that reason, currently available therapies are palliative and have led to inconsistent results. The adipose tissue has been recognised as a reservoir of pro-inflammatory cytokines, which are directly involved in cell differentiation and proliferation, influencing fibrogenesis and wound healing. And, as the keloid is considered as a pro-inflammatory scar, increased adipose tissue could be a risk factor. Therefore, the objective of the present study was to evaluate the body mass index (BMI) of patients with keloids. Methods: Analytic, observational, cross-sectional, controlled study. Forty-three patients with keloid and 39 patients with normal scars were enrolled and had their BMI measured. All scars in both groups were at least one year old. Patients were selected from Plastic Surgery Outpatient Clinic. Results: BMI was higher in the keloid group than in the control group (p = 0.034). There was a higher prevalence of skin colour "white" patients (p = 0.003). Conclusion: Patients with keloid had higher BMI than those with normal scars. This result reinforces the hypothesis of the neuroimmunoendocrine nature of keloid in which the inflammatory pathway (with the production of proinflammatory mediators by the adipose tissue) plays a pivotal role, as in other skin diseases such as psoriasis.


Adaptive modulation techniques have the potential to substantially increase the spectrum efficiency and to provide different levels of service to users, both of which are considered important for third generation cellular systems. In this work, we propose a general framework to quantify the potential gains of such techniques. We characterize the optimum throughput of the system with adaptive modulation and power control, and then propose an iterative algorithm that converges to this optimum. Numerical analysis shows that (i) adaptive modulation even without power control has significant throughput advantage over SIR-balancing power control; and (ii) the proposed iterative algorithm converges to the optimal in very few steps. The first observation is especially important from an implementation point of view. Adjusting the modulation level without changing the transmission power does not involve the repeated measurements and feedback, which significantly simplifies the implementation. This work provides valuable insight into the performance of adaptive modulation in multi-user environments.


Apatite nuclei were precipitated in the pores of silicagel microspheres by raising pH of simulated body fluid (SBF). By a soak in SBF, hydroxyapatite (HAp) was induced from the apatite nuclei and spread over whole surface area of the silicagel microspheres. Then encapsulated silicagel microspheres with HAp were fabricated.


This study is concerned with the stability and performance analysis, stabilisation and ℋ∞ control problems for continuous-time switched stochastic systems. By applying the average dwell time method and the piecewise Lyapunov function technique, a sufficient condition is first proposed to guarantee the mean-square exponential stability for the unforced switched stochastic system. Also, a condition on a weighted ℋ∞ performance is proposed. The stabilisation and ℋ∞ control including both state feedback control and dynamic output feedback control are considered. Numerical examples are provided to illustrate the effectiveness of the proposed theories.


Single cross-sectional measures of racial discrimination may mask the dynamic nature and cumulative impact of repeated exposures to discrimination. Characterizing racial discrimination trajectories, patterns of repeated exposure, may provide insight on age-related patterns of health risk and resilience. However, there is a dearth of research exploring racial discrimination trajectories. This study characterizes racial discrimination trajectories and identifies trajectory correlates among a nationally representative sample of middle-aged and older black adults who participated in the Health and Retirement Study (2006-2018). Repeated measures latent profile analysis was employed to identify racial discrimination trajectories. Logistic regression models, estimating odds ratios (ORs) and 95% confidence intervals (CIs), were conducted to investigate sociodemographic and neighborhood-level predictors of racial discrimination trajectories. Two racial discrimination trajectories were identified: low to moderate (82%) and persistently high (18%). Individuals 65+ (OR: 0.45; 95% CI: 0.32, 0.64) and female sex (OR: 0.59; 95% CI: 0.45, 0.76) were associated with a lower odds of belonging to the persistently high racial discrimination trajectory class. Individuals reporting higher levels of major lifetime experiences of discrimination (OR: 1.47; 95% CI: 1.33, 1.63) and greater neighborhood social cohesion (OR: 1.30; 95% CI: 1.1, 1.50) predicted membership in the persistently high racial discrimination trajectory class. These findings suggest heterogeneity in the cumulative patterning of discrimination among black middle-aged and older adults. Discrimination trajectories may enable greater precision in estimating the health consequences of cumulative exposure to discrimination. Future studies are warranted to determine whether membership in specific trajectory classes confers differential risk to age-related conditions.


The aim of the present investigation is to study the economic feasibility of development of 30 MW wind power plant (wind farm) at Turaif, Northern Province of the Kingdom of Saudi Arabia (K.S.A.) by analyzing long-term wind speed data. Western and Northern provinces of K.S.A. have relatively better wind energy resources. The study indicates that monthly average wind speeds of Tuuraif (31 41' N, 38 40' E) vary from 3.4 to 4.4 m/s at 10 m height. The wind farms simulated consist of different combinations of 600 kW commercial wind machines (50 m hub-height). NREL's (HOMER Energy's) HOMER software has been employed to perform the technoeconomic assessment. The study presents monthly variations of wind speed, cumulative frequency distribution (CFD) profiles of wind speed, monthly and yearly amount of energy generated from the 30 MW wind farm (50 m hub-height), cost of generating energy (COE, $/kWh), capacity factor (%), etc. The CFD indicates that the wind speeds are less than 3 m/s for 46.5% of the time during the year at Turaif. This implies that wind electric conversion systems (WECS) will not produce energy for about for 46.5% of the time during the year. The annual energy produced by 30 MW wind farm (50 m hubheight) has been found to be 39752 MWh. The cost of windbased electricity by using 600 kW (50m hub-height) commercial WECS has been found to be 0.0579 US$/kWh. With the development of 30 MW wind farm, about 1598 tons/year of carbon emissions can be avoided entering into the local atmosphere. The paper also shows effect of hub-height in wind farm development.


Cosmological perturbations are considered in f(T) and in scalar-torsion f(φ)T teleparallel models of gravity. Full sets of linear perturbation equations are accurately derived and analysed at the relevant limits. Interesting features of generalisations to other teleparallel models, spatially curved backgrounds, and rotated tetrads are pointed out.


In the mid‐1980s, social work, which had been practised in China in the years before 1949, was reintroduced as a newly imported social discipline. Like many other imported social ideas and practices, such as the free market, it was not well‐adapted to the socialist ideology of China and, therefore, was required to exhibit 'Chinese characteristics', (a term proposed by Deng Xiaoping to justify the economic reform in the early 1980s). In this paper, we first examine the discourse relating to Chinese characteristics in selected social work literature published in China. Then we report the findings of a qualitative study of 32 social work graduating students to gain an empirical understanding of these students' perception of the Chinese characteristics of social work. The implications of social work development in China and international social work are also discussed. 在20世纪80年代中期,社会工作在中国再度恢复了在社会科学中的学科地位。正如许多其它外来的思想和实践方法,如自由市场等概念一样,都没有被调整以适应"中国特色"的社会主义意识形态((此概念在20世纪80年代初由邓小平提出)。在本文中,作者首先根据一些在中国出版的中文文献,研究有关中国社会工作特色的论述。然后,作者通过对32名社会工作毕业生的定质研究去了解这些学生对中国社会工作特色的看法。本文也讨论了中国社会工作发展对国际社会工作的影响与含义。


Background: Hypertension in pregnancy with or without proteinuria is one of the foremost reasons of maternal death and morbidity in the world. This study investigated the role of a high calcium diet (HCa) in N G -nitro-L-arginine methyl ester (L-NAME) administered to pregnant rats. Methods: Thirty-two female rats of the Sprague-Dawley strain were randomly assigned into 4 groups of control, L-NAME (0.3g/ L of water), L-NAME + HCa (2.5%), and HCa diet (2.5%) group. Following confirmation of mating, HCa was administered from day 3 to day 18 of pregnancy while L-NAME was administered from day 12 to 18. The rats were sacrificed on the 19th day and blood pressure measurements were obtained. Blood and placenta were collected for biochemical and oxidative assays. Results: Blood pressure was reduced in L-NAME + HCa rats compared with L-NAME (p<0.05). Placenta and fetal weight were decreased in rats receiving L-NAME, L-NAME + HCa and HCa compared with control (p<0.05). HCa diet had no effect on L-NAME impaired oxidative status. No significant difference was observed in the liver enzymes and CRP levels across the groups. However, there was a significant reduction in the platelet count of L-NAME + HCa and HCa groups when compared with the control and L-NAME. Calcium and magnesium levels in the serum and placenta homogenate were not different but their excretion was significantly increased in the urine samples of the L-NAME + HCa and HCa groups. Conclusion: This study showed that HCa reduced the blood pressure of pregnant rats administered L-NAME but had no effect on oxidative stress. This implies that HCa alone might not sufficiently ameliorate the negative effects of hypertension in pregnancy.


We analyze the Raman spectra of nanocomposites based on ultrahigh-molecular-weight polyethylene with nanoclay, thermoexpanded graphite, and reduced graphite oxide fillers. We discuss the potential of Raman spectroscopy for quantitative analysis of the nanocomposite structure, the influence of the fillers on the phase and conformation compositions of the polymer matrix, as well as for the monitoring of dispersion of the nanographite fillers in the nanocomposites.


Multilevel converter technology has emerged as a very important alternative in the area of high-power medium voltage energy control. The voltage source inverters produce a voltage or a current with levels either 0 or ±V dc they are known as two level inverters. To obtain a quality output voltage or a current waveform with a minimum amount of ripple content, they require high switching frequency. In high power and high voltage applications, these two level inverters, however, have some limitations in operating at high frequency. The multi-level inverter is to synthesize a near sinusoidal voltage from several levels of dc voltages. As number of levels increases, the synthesized output waveform has more steps, which provides a staircase wave that approaches a desired wave form. Also, as steps are added to waveform, the harmonic distortion of the output wave decreases, approaching zero as the number of voltage levels increases. Referred to as cascaded-inverters with Separate DC Sources (SDCs) or series connected H-bridge inverters. This paper multilevel converter fed induction motor drive with different voltage levels is considered and simulation results are presented in terms of total harmonic distortion (THD). The PWM signal thus generated is then used as triggering pulses for the multilevel inverters.


Taking the 600 mm round bloom as research subject,a 1-D transient mathematical model in cylindrical coordinate system was built to describe heat transfer during the solidification of round bloom,and the temperature field of round billet with diameter of 600 mm was computed based on the mathematical model.The influences of casting speed,superheat,and the steel grade on the surface temperature and solidification process were analyzed.The results show that the primary influence on the position of solidification ending was due to the casting speed,solidification ending will move 3.87 m in the withdraw direction per 0.05 mm increase of casting speed.The computing results comply with the actual measured data well.


New calls for higher R&D expenditures are now heard almost daily. Even such normally dissonant voices as those of President Bush, Congressman Richard Gephardt and the AFL-CIO have joined in the same refrain: the United States must spend more to develop exciting new technologies if it is to regain the competitive high ground. But before we launch a full-blown R&D offensive we may need a better survey of the strategic terrain. The complexity of this subject has eluded many well-meaning promoters of greater R&D spending. They too often see R&D as a "homogeneous input," and urge us to push more ingredients into the sausage machine, without paying careful attention to the proportions. We have, in particular, neglected the importance of the ratio of process to product R&D. A review of data on R&D spending and its effects yields a somewhat complicated picture. In absolute terms, the U.S. still outspends its international competitors on R&D, at both the government and industry levels. In 1988, Japanese spending stood at 66 percent of total U.S. spending, in current dollar values. Expressed in purchasing power parity terms, as calculated by the OECD, Japanese expenditures were a mere 38 percent of U.S. outlays. By 1989 (the last year for which data are available) Japanese spending was 62 percent of U.S. spending in current dollar terms. A more commonly quoted statistic compares R&D expenditures as a proportion of GNP, a measure by which the U.S. no longer holds the lead. Non-defense 1989 R&D expenditures as a percentage of GNP were 1.9 for the U.S., versus 3.0 for Japan. But this statistic is misleading: It is subject to what economists call "aggregation bias," which masks important structural and industry differences in the economies being compared. For example, the U.S. economy is far more diverse than those of its principal competitors, and many U.S. products that are quite competitive in the international market (coal, logs, grains, meat products, nails, tobacco and cigarettes, as well as important sectors of our large service industries) would derive little benefit from a more intense R&D effort. Research provides evidence that, although the absolute level of U.S. R&D spending relative to other countries certainly matters, it is at least as important to consider what proportion of our total R&D spending goes toward new product innovation, and what proportion toward developing new or improved manufacturing processes. It turns out that, by these measures, U.S. and Japanese firms allocate their R&D budgets very differently. 81% PRODUCT R&D My 1991 study for the International Trade Commission on the effects of product and process innovation on the trade balance between the U.S. and Japan found that, as anecdotal evidence suggests, U.S. industry has focused almost exclusively on product innovation. A sub-sample of 1,119 manufacturing firms and their subsidiaries was created from the National Science Foundation's R&D survey. These companies broke down their R&D expenditures between 1979 and 1985 into product and process categories. Of these expenditures, 81 percent went to product innovation, while only 19 percent went to process innovation (see Table, next page). (Table omitted) Meanwhile, in a Japanese government survey of companies performing R&D over the years 1983 to 1988, 26 percent said they were actively working to improve the technology of their own manufacturing processes, while 46 percent were working to incorporate technology recently developed by others into their production processes. But, surprisingly, only 17 percent of the Japanese firms were engaged in new product development: a proportion almost directly inverse to that among American firms. These results point to an even starker difference between U.S. and Japanese firms than that found by a distinguished scholar in this field, Edwin Mansfield(1). …


Functional disorders with motor deficits of the sacroiliac joint (SIT) is characterized by local and radiating pain. They can cause secondary occurred
scoliosis, blockages and various clinical syndromes ~ dysmenorrhea, morbus Crohn, chronic adnexitis, and others.
The aim is to create and test Physiotherapeutic (PT) methodology, combining manual techniques and analytical exercises for patients with dysfunction of the sacroiliac joint and chronic pain syndrome in the lumbosacral area.


This essay investigates an approach to writing about animals within the humanities. The goal is to focus attention on animals as actors, rather than speaking on their behalf. By combining Mikhail Bakhtin's theory of speech genres with Donna Haraway's perspectives on co-habitation between all species, I suggest that a careful attention to animals as communication partners might give us a tool to capture the contribution animals make in the creation of history and culture. Two examples will be provided to illustrate this concept: The first example is a media story about celebrity polar bear Knut. The second example is an oral account of human-animal interaction in the zoo.


This study investigates parents' experiences and their views on labour force participation and childcare arrangements. The research focuses on early childhood care and education arrangements, organisation of employment, and parental leave policies. Participants were 60 families with 5-year-old children, selected randomly from 14 schools in the greater Wellington region. In total, 101 people (59 women and 42 men) were interviewed. The families included: 41 families with 2 parents, where both the mother and the father were interviewed; 7. mother-only families and 1 father-only family; 1 family where the grandmother was the sole caregiver; and 10 families with 2 parents where only the mother was available for an interview. An in-depth interview about past and present employment and childcare arrangements was conducted with each consenting parent. There was a high incidence of pardcipation in the early childhood education and care services. Playgroups were attended most often when the children were aged under 1 year, playcentre and childcarr centres were used more often when the children were aged over 1 or 2 years, and among 4-year-olds, kindergartens were the type of service most frequently used. Concurrent use of more than one early childhood service was relatively widespread. The benefits of early childhood care and education for parents and children usually concerned socialising and socialisation, and creative and learning activities were further benefits for the children. Difficulties concerned aspects of socialising, travel or transport to the early childhood centre, and fees or financial considerations. Caring for the children before they started school was primarily the responsibility of the mothers. A few fathers had this responsibility. Informal care arrangements most often involved grandparents. Mothers were often responsible for caring for their children when they were sick, before school, after school, and in the holidays. Within the 2-parent families, reading and learning activities at home were more likely to be a shared responsibility. Most parents thought that reading at home was working out fairly well, and spontaneously made positive comments on their children's motivation or progress. Mothers were more likely to talk about the child's motivation. Time pressures were a problem for . some parents in paid work. In total, 67% of the women and 98% of the men interviewed had participated in paid work during the child's first 5 years of life. The percentage of mothers working full time increased to 19% by the year the children were 4 to 5 years of age. Each year from the child's birth up until school entry, over a third of the fathers were working 50 hours or more per week. There was some dissatisfaction among the fathers about the hours spent in paid work. Income was seen as the main benefit of paid work. Mothers also said that interest in the work itself and having contact with adults were benefits. Difficulties for parents who had worked during the child's first 5 yens were missing out on having time with their children, time pressures, fitting in household tasks, guilt, and finding appropriate childcare. Financial difficulties influenced many parents' views on mothers of young children working.


This study investigated first year university students' willingness and anxiety levels in speaking English in EAP classrooms. UCS and FLCAS were employed to create a questionnaire and collect 31 participants' responses. The major findings are as follows: a) participants demonstrated a higher than average WTC in a broad sense; b) only one third of them reported feeling anxious about speaking English in EAP classes; c) the fear of being negatively commented on, getting involved in communicative scenarios, and making English speeches are the three main anxiety sources that negatively correlate with WTC, with only negative evaluation as the negative predictor.


A persistent hog-corn price ratio has been known to exist since the early 1930s and many attempts have been made since then to model its dynamics. That these models have been ineffectual as forecasting tools is apparent by the fact that the hog cycle has persisted to this day. In this paper I propose that increased forecasting accuracy can be obtained by adjusting traditional forecasting models so that they account for deterministic, nonlinear processes. With improved forecasts, the costs of countercyclical production will decrease, dampening and perhaps even eliminating the cycle. The chaotic dynamics of the hog-corn price cycle is confirmed, and chaotic models of this system are developed. The analysis provides the framework for developing a function to forecast the dynamics of the hog-corn price ratio.


In electrocatalytic water splitting, active, stable and low-cost hydrogen evolution electrocatalysts play key roles in the conversion and storage of renewable energy sources.


Recently Aoi et al.[1] reported unusual results for the surface acceleration of the KiK-net IWTH25 station in response to the 14 June 2008 Iwate-Miyagi mainshock, moment mag- nitude 6.9. Accelerations as large as 4g were observed with the acceleration waveform showing distinctive asymmetry, i.e., large, positive accelerations of short duration were bal- anced by small, negative accelerations of long duration. These observations prompted the sobriquet trampoline effect for it seemed that the earth surface was moving much like a jumper on a trampoline. To understand what is going on we undertake examination of the IWTH25 station data sets and introduce a model for what is seen. Examination of the data at the IWTH25 station show the asymmetric vertical acceleration (initially noted by Aoi et al.[1]) and most importantly strong correlation between vertical mo- tion and horizontal motion. A lumped element model[2] for this system, involving nonlinear surface-subsurface coupling, is introduced and shown to have...


In the crystal of the centrosymmetric title compound, C20H20N2S2, molecules are linked by head-to-tail C—H⋯N hydrogen bonds, resulting in chains extending along the a axis. Three additional C—H⋯π intermolecular interactions give rise to a herringbone packing motif which extends along the c axis. The C—H⋯N interactions provide links between the sheets.


In this paper, we unify various axiomatisations of the core of TU games by means of consistency with respect to different definitions of reduced games. First, we introduce a general definition of reduced games including the reduced games due to Davis and Maschler (1965), Moulin (1985), and Funaki (1995) as special cases. Then, we provide a general theorem from which the characterisations due to Peleg (1986), Tadenuma (1992), and Funaki (1995) can be obtained. Our general theorem clarifies how the three characterisations of the core differ and are related.

In Teamsters and Turtles? U.S. Progressive Political Movements in the 21st Century, editor John Berg has compiled a diverse collection of analytical and descriptive writings focused on the struggles, constituencies, and agendas of individual Social Movement Organizations (SMOs). The work clearly draws inspiration from the WTO protests, which engendered cooperation between labor, environmental, and other left organizations with political motivation to challenge globalization. It explores potentials for expanding and strengthening linkages between movements and organizations with progressive interests or constituencies. Berg asks, "How can the progressive social movements that came together in Seattle unite more firmly and continue to grow in the future?" (p. 10). To varying degrees, all articles in the anthology reflect on the history, membership, aims, strategies, effectiveness, challenges, and future directions of 10 separate social movements. According to Berg, the movements represented in the book were chosen because of their potential to forge a larger coalition in the future, although it is not always clear what the basis for this potential might be. The first article, by Ronald Hayduk, explores the anti-globalization and global justice movement, and considers the case of Global Exchange. This was among the more satisfying works in the volume, because it clearly embodies the unity across movements and other themes that the book sets out to explore. In this chapter, we see that the Seattle protests of 1999 were the culmination of previous activism, and Hayduk helps us understand the mix of structure and agency that created the conditions for the rise of this movement: a combination of profound economic shifts laying the political groundwork for activists to create new models of collaborative resistance. Somewhat predictably, the movement is marred by disagreements around goals, ideology, targets, and tactics. Also not surprisingly, there are significant tensions around the differing cultures and social locations of participants. Hayduk illustrates the loosely linked and highly fragmented nature of this movement, even as he highlights several of its "redeeming" characteristics: "it is decentralized, but coordinated; it acts spontaneously, but is well organized; it uses innovative protest tactics effectively; it is clever and witty; and it is democratic and optimistic" (p. 24). A more depressing story emerges from Immanuel Ness's description and analysis of the labor movement. He describes a structure enmeshed in interest group politics that not only separates labor from a number of progressive movements, but also fractures the labor movement internally. He presents a fairly bleak picture, both in terms of the status of the movement and the possibilities for coalition building. Although the many devastating consequences of globalization create a compelling motive for strong intra-movement and inter-organizational cooperation, the structural difficulties of organizing against it often preclude effective movement building. Ness argues that organizing strategies and hierarchical governing structures rooted in the 1930s have proved


On the basis of an analysis of the traffic behaviour and accidents it is examined at selected one-way traffic tunnels with underground junctions and turn-offs to what extent such special structures are admissible and by which criteria of use they are governed. The evaluations of the traffic measurements show that the various types of entrances and exits influence the traffic flow in a different way. In general, negative effects can be expected in the case of wedge-shaped entrances because of the considerable differences of speed between the main stream and the side stream on a short merging distance. The analysis of accidents does not reveal any hazardous points existing as a consequence of underground junctions and turnoffs respectively. In most cases the accidents are not caused by tunnel-inherent problems.


Quality assurance of nuclear medical equipment provides the fundamental basis for correct results of patient investigations with respect to optimization and radiation protection. To achieve that reference values are determines and action levels and limits of tolerance have to be put down. Starting points are acceptance tests that prove that the manufacturer's specifications are fulfilled and that the system is working optimally. Routine quality control procedures are used to make sure and document malfunctioning and deviations from reference values.


Multiple primary tumors are uncommon in patients with squamous cell esophageal cancer. Conventional
imaging methods have limitations in detecting those tumors. Although 18-F-fluoro-deoxyglucose-positron
emission tomography scanner increases the detection of multiple synchronous tumors in patients with other
malignancies, its contribution in patients with squamous cell esophageal cancer has not been assessed as it
is not systematically performed. The detection of synchronous skin squamous cell tumors in patients with
squamous cell esophageal cancer presents a challenge for making diagnostic and therapeutic decisions. A
metastatic tumor leads to palliative management, whereas the diagnosis of a primary skin tumor requires
curative treatment of both squamous cell tumors. Pathological evaluation appears crucial in the decision.


The Building Research Establishment (BRE) has developed a blended cement based on high alumina cement (HAC) with ground granulated blastfurnace slag. This cement has been given the trademark 'BRECEM' and the properties of concrete made from the new cement are being studied at BRE in collaboration with the industry. In this paper, the chemical and thermal stability of BRECEM and HAC mortars and concretes is compared as a necessary preliminary to determining engineering properties in due course. Concrete durability studies are at an early stage and, as such, the uses for this cement are still under development. The addition of slag alters the course of hydration reactions in HAC. A chemical compound, gehlenite hydrate (stratlingite), not seen in plain HAC in significant amounts, forms readily and becomes the major hydrate constituent in due course, and is thought to provide a more stable phase assemblage. Studies to determine the chemical and physical properties of BRECEM in mortars and concrete over a range of temperatures and storage conditions have been set up at BRE. BRECEM mortars show excellent sulphate resistance. HAC and BRECEM concrete durability specimens have performed very well following storage for a year in aggressive sulphate, marine and soft water environments. Longer term tests will be carried out at two, five and 10 years. BRECEM concretes have shown a greater tolerance to high water-to-cement ratio mix designs in forming stable assemblages with reduced temperature rises and enhanced durability, and there are cost savings compared with HAC concretes. A number of potential, practical applications have been advocated.


The current study was designed to investigate effect of copper administration on oxidative damage to the brain in ApoE−/− mice and to explore the putative neuroprotective effects rendered by apolipoprotein E (ApoE). Male C57BL/6 ApoE−/− and wild-type mice were randomly assigned into four groups, ApoE−/− mice wild-type mice treated with either copper or saline. Copper sulphate pentahydrate or saline (200 µl) were administered intragastrically daily for 12 weeks. Expression of malondialdehyde, superoxide dismutase (SOD), hemeoxygenase 1 (HO-1), and NAD(P)H: quinone oxidoreductase 1 (NQO1) were determined by a combination of biochemical assays. The concentration of copper in the brain of C57BL/6 mice and ApoE−/− mice treated by copper significantly increased compared with mice treated by saline (P=0.0099 and P=0.0443). Compared with the C57BL/6 mice treated by copper, the level of the ApoE−/− mice treated by copper was higher (P=0.018). TBARS and SOD activities or the expressions of NQO1 and HO-1 in the brain were not significantly different amongst the four experimental groups of mice. The relative value of NQO1/β-actin expression in the brain of the ApoE−/− mice was similar in both saline and copper administration experimental groups. However, Western blot analysis showed that NQO1 expression was significantly higher in the ApoE−/− mice brain treated with saline compared with saline treated wild-type mice (P=0.0449). ApoE does not function in protecting the brain from oxidative damage resulting from copper build-up in Wilson's disease, but may play a role in regulating copper accumulation in the brain.

Objective: Neutrophil lymphocyte ratio (N/L) and mean platelet (Plt) volume (MPV), the markers of systemic inflammatory response, has been investigated in many cancers, but data for head and neck cancers and thyroid carcinoma are limited. It had been purposed to study N/L, MPV, and Plt levels in papillary thyroid carcinoma (PTC) as a diagnostic marker. Material and Methods: A total of 104 patients, had undergone ultrasonography (US) guided fine needle aspiration (FNA) and thyroidectomy, for indicated cases, between April 2010 and August 2013, were enrolled in the study and the laboratory tests, regarding N/L, MPV, and Plt, of the cases had been collected retrospectively. Results: No any difference was stated between PTC and benign nodular thyroid diseases (BNTD) in terms of age, gender, size of the nodule, N/L, MPV, and Plt (p>0.05). Conclusion: The preoperative inflammatory hematological parameters, in terms of N/L, MPV, and Plt, may not be useful as a predictive diagnostic marker of the thyroid malignancy, PTC.

ABSTRACT The effects of environmental conditions on the flowering of Majorana syriaca L. (= Origanum syriacum var. syriacum) were studied. Under natural conditions, flowering starts at the beginning of May. Full bloom was observed in two flushes from early June until September. M. syriaca was found to be an absolute long-day plant, requiring at least 28 long days (LD) for flower initiation. More LD were, however, required for the completion of flower formation and hormal development of the inflorescences. The critical day length for flower induction was 12 h, but full flowering required a longer photoperiod. Photoperiodic flower induction is not transmitted from one branch to another. There is no cold requirement for flowering in M. syriaca. Increased growing temperatures reduced the time needed from the start of long-day treatment to anthesis, but high temperatures greatly decreased the number of flowers. Decreasing light intensity in the field by shading delayed flowering and reduced the proportion of i...


BACKGROUND : Knowledge of course and branching pattern of major arteries is very important for the vascular surgeons & plastic surgeons. METHOD: This study was carried over a span of three years on 30 human cadavers in the department of anatomy, osmania medical college, Hyderabad, telaganastate , India. Dissection instruments were used for dissecting the entire upper limb in all the cadavers according to the steps of the cunnigham's manual and variations are noted RESULT : In our study we observed variant course and anamolous branching pattern of major arteries in upper limb particularly in the region of axilla , arm and forearm.In our routine dissection of cadavers in anatomy department we observe these variations particularly in axillary , brachial and other major arteries in arm and forearm. In our present study this type of gross variation we found in one body out of 30 cadavers.these variations in the both limbs also different . In the left upperlimb of this cadaver  3 rd part of axillary artery is devided into large superficial (60%)(we named it as superficial  brachial artery) and small calibre deep branch(40%)(we named it as deep brachial artery )one centimeter below the pectoralis minor at the lower border of lattissmusdorsi muscle and infront of the teres major muscle. Deep Brachial artery is possibly a high-origin artery of the common interosseous. The course of this artery resembles the course of the brachial axial artery of the embryo. It supplies the anterior compartment of brachial muscles and continues as the common interosseous artery. The large caliber superficial artery ( Superficial Brachial artery )  lies antero medial to the median nerve and also superficial to the nerve through outit's course in the arm and reaches base of the cubital fossa where it lies deep to the bicipital aponeurosis medial to the tendon of biceps femoris. Superficial Brachial artery  is possibly a high-origin and persisting embryological radial artery. It gives no collaterals in the arm. At the base of the cubital fossa it divides into two equal-sized radial and ulnar arteries at the condylar line of humerus instead of at the neck of radius in the cubital fossa. CONCLUSION: Although the abnormal branching pattern is quiet infrequent ,according to this study, here we get only in one limb out of 60 upperlimbs , the frequency rate is only 1.6% even though frequency is in narrow range it is essential to know such rare variations.


As can be seen, the verb remember may take a to-infinitive clause (1a) or a gerundial -ing-clause (1b) as clausal verb complement. Language users cannot choose freely between one or the other pattern; rather, the variation can be characterized as functional differentiation, whereby the to-infinitive encodes a situation which is not yet actualized at the time of remembering, whereas the gerundial -ingclause encodes the situation as actualizing before or at that time. However, in the alternation pattern in (2) with regret (that-clause vs. gerundial -ing-clause), preference for one or the other verbal complement is far less categorical; actually, it would appear that both variants are freely interchangeable.


Aims: The research was conducted to determine the effect of parents' stress levels related to the COVID-19 pandemic on digital parenting awareness. Materials: This descriptive study was conducted between November 2020-January 2021 with 452 parents residing in Turkey, whose children attended primary school. The data were collected online with a data collection tool consisting of the PSS and the DPAS. Results: It was found that the variables of occupation and number of children of the parents participating in the research are influence the mean scores of DPAS, while the variables of occupation, age, income perception, adaptation to the pandemic process, time spent with the child and the way the relationship with family members are perceived are influence the mean scores of PSS. It was found that, among the characteristics of using digital tools, the parent's phone/tablet usage time, the parent's daily phone/tablet usage time, and the child's status of having his/her own tablet were effective on the mean DPAS score; the variables of parents not knowing their children's use of smart phones/tablets for playing games, homework or educational purposes and not knowing the usage for what purpose were effective variables the mean PSS score. The total mean score of DPAS was determined to be 45.13±9.06, and the mean total score of PSS was determined to be 13.82±2.82. Conclusion: As a result of the research, it was determined that the stress levels perceived by the parents had an effect on digital parenting awareness.

Two mutation methods of N+ ion implantation and Cs137-γ-ray irradiation were used to treat Arthrobacter simplexa,nd to obtain the mutant with high C12,-dehydrogenation activity from 17α-methyl-testosterone to dehydrogen-methyl-testosterone.The original A.simplex TCCC11042,which was screened from 16 strains of A.simplex based on the re-sult of dehydrogenation of 17α-methyl-testosterone in flask,was mutated by N+ ion implantation and Cs137-γ-ray irradiation successively.The results show that one positive mutant F2-20 from TCCC11042 was bred,and the mutant had a high bio-conversion ratio of 60.8% from 17α-methyl-testosterone to dehydrogen-methyl-testosterone,which was higher 12.8% than the original strain TCCC11042 with only 48%.The mutant kept a stable heredity with higher C12,-dehydrogenation of 17α-methyl-testosterone after colony successive inoculation test.


This paper expands upon our previous research in the field of BrainComputer Music Interfacing and reports on tools for performance and composition controlled via brainwave activity in development at ICCMR, University of Plymouth. Our approach measures electroencephalogram (EEG) data elicited via generating Steady State Visual Evoked Potentials (SSVEP) to allow for real-time control of musical parameters. This paper presents Flex, a solo performance piece designed for a portable BCMI (Brain-Computer Music Interface) system. Flex serves as a demonstration of the mapping complexities and control on offer through interfacing brainwaves with a musical system.


This study uses a survey of undergraduate college students at two schools in the eastern United States to investigate their attitudes toward carrying concealed weapons on campus. We found that politically conservative white men who own guns are more likely to be in favor of qualified students and faculty carrying concealed weapons on campus than politically liberal non-whites and women who do not own guns. Neither academic major nor age had a significant effect on any of our dependent variables.


practitioners (GPs) managing funds in order to purchase health services for the patients under their care. The aim was for decisions about purchasing and providing health care to be taken as close to the patient as possible, by their own GP. It has meant that two forms of purchasing have grown side by side health authority and GP fundholding. Subsequent policy changes have made fundholding accessible to more practices, and have extended the fundholders' areas of


A model for a winding stockroll of conductive material at dynamic equilibrium potential is described. The basic premise of the model is that at equilibrium the conductive and convective currents in the final web span must be equal and opposite at all points, so that the total current is zero. The result of this requirement is that the equilibrium stockroll potential is an exponential function of web resistivity, web velocity, capacitance to the ground of the final span, and the length of the final web span. This exponential relationship has a common V/sub 0/ of about 1300 V at a point closely following the last roller, for a particular web span. The predictions of the model are in very good agreement with experimental winding results in the range of web resistivities and velocities encountered in practice.<<ETX>>

Pefloxacin (PFLX) is a type of fluoroquinolone (FQ) that has been widely used in aquaculture and animal husbandry. It is also a new kind of pseudo-persistent pollutant, which has some toxic effects. In this study, zebrafish (Danio rerio) embryos were used as exposure models to analyze the toxicity of PFLX. The results showed that PFLX was absorbed on the outer membrane surface at the beginning, and then a few PFLX slowly entered the cytoplasm. The adsorption complied with the Langmuir isotherm adsorption model. The surface morphology of the embryonic membrane was changed. PFLX exposure had no effect on fetal autonomous movement, but it significantly inhibited the embryo hatching rate. After PFLX exposure, the embryo and larval survival rates showed a clear dose–effect relationship. Though PFLX exposure did not cause teratogenic toxicity, it still affected cardiovascular function. The potential toxicity mechanism and developmental toxicity of PFLX to zebrafish were revealed. These results could be important for studies concerning FQ toxicology.


Flow control using synthetic jets has been computationally investigated to improve aerodynamic performance of blended wing body configuration under different jet location at a relatively high angle of attack. Experimental and numerical data were examined by analyzing the baseline characteristics of a blended wing body configuration when synthetic jet was off. Based on the aerodynamic data and flow structure, a strategy for flow separation control on the blended wing body configuration was established. Two types of exit locations were considered: one is outboard array jets, and the other is inboard array jets. The interactions of synthetic jets with a free stream were performed by analyzing the vortical structure and the surface pressure characteristics. The effectiveness of flow control was evaluated by examining the aerodynamic coefficient and flow structures. As a result, the vortex breakdown point is moved toward the outboard section by synthetic jets, and the separation flow shows a stable structure. This indicates that the synthetic jets under suitable actuating conditions beneficially change the local flow feature and vortex structure to bring a significant improvement of the wing aerodynamics acting on the blended wing body configuration in the stall angle.


The paper deals with the detailed analysis of the flux linkages, motor thrust and friction force of the linear synchronous reluctance motor (LSRM). The flux linkages, the motor thrust and the friction force are determined experimentally. Their characteristics, given as functions of the position and the direct and the quadrature axis currents, are used to introduce the nonlinear dynamic LSRM model. The agreement between measured and calculated results in the case of the test at blocked primary and in the ease of kinematic control is very good. The presented results show that the motor thrust calculated by using flux linkages should be used with caution especially if an accurate position dependent motor thrust is required.


In this study, we embraced a positive psychology perspective in explaining how hopeful employees can be created by benefiting from authentic leadership style, an empowering, transparent and nourishing leadership style that is encouraged by positive organizational behavior scholars. In order to understand this leadership style's effects on followers perceived organizational support and hope we built a model explaining effects of perceived organizational support as a mediator in the relationship between authentic leadership and hope felt by followers. We tested this model on 237 white collar workers in service industry in Istanbul region. We preferred face to face survey method and we analyzed our data in SPSS 20.0. Results of the study showed that authentic leadership behavior has statistically significant effects on both perceived organizational support and hope and results confirmed that perceived organizational support acts as a moderator in the relationship between authentic leadership behavior and hope felt by followers.


Background: A health care team comprises of doctors, nurses, paramedical staff, medical assistants, administrators and support staff or class 4 workers. Each individual has a role in the execution of proper health care delivery to the patients. Obstetrics and gynecology is a dynamic branch requiring urgent attention in most cases right from admission to discharge. Delivery of prompt treatment is possible with better training and coordination of the health care team. In a tertiary care institute, referred patients have more critical health problems and need urgent assistance by well-trained staff. On the other hand, in a smaller set up with less human resource, agile and well-trained support staff would be an asset to overcome the limitations. Better-trained staff means less loss of man-hours from injuries and illnesses, less medico legal liabilities, reduced maintenance cost of equipment and less expenditure on health-related issues of staff. We conducted an interview based cross sectional observational cohort study of the situation and an assessment of needs for skill building of support staff in a tertiary care hospital. At the end, we propose a structured training program suitable to the local needs that can be conducted by experienced peers, technical staff and medical personnel. We studied unmet training needs of the staff and gender related issues. Methods: A questionnaire based cross sectional study involving 92 class 4 workers in the department of obstetrics and gynecology in a tertiary care hospital was conducted comprising questions regarding their demography, work profile, training, needs and problems faced. Key informants in the relevant area were also interviewed. Results: Graphical representation of the responses received has been made. Professional work profile, health issues, gender issues, training need of any specialized training has been highlighted. Conclusions: As an important part of the health care team, this study has brought out issues related to health especially occupational health, needs for training, hurdles faced at work amongst class 4 staff working in the department of obstetrics and gynecology.


PURPOSE Globally, black women experience poorer breast cancer (BC) outcomes suggesting the need for effective health promotion approaches to increase perceived severity and improve screening practices for early detection. Although, narrative communication by patients or survivors are increasingly considered an effective approach for better BC outcomes, there is limited information on its use in Nigeria. This study assessed the self-efficacy and willingness of BC patients and survivors at the University College Hospital, Ibadan to implement narrative communication interventions. METHODS This study utilized a mixed-method convergent parallel design. Five patients were recruited for in-depth interviews (IDI). A semi-structured questionnaire was used to collect data from 102 patients on perception and the generalized self-efficacy to implement narrative communication interventions. Data were analyzed using thematic analysis for qualitative and descriptive and inferential statistics for quantitative data. RESULTS Mean age of the respondents was 49.3 ± 10.2 years. Over three quarters (79.4%) of respondents had good self-efficacy to implement narrative communication. Majority of respondents (87.3%) were willing to share lived experiences during narrative communication interventions. Over 90% (94.1%) agreed that health programs on BC anchored by patients and survivors will enable individuals make healthy decisions than interactions with clinicians only. Respondents' educational attainment was significantly associated with perception and self-efficacy to implement narrative communication intervention programs (P < .05). Patients opined that a pre-diagnosis discussion with a BC patient or survivor would have increased their perceived severity and susceptibility. CONCLUSION This study highlights the potentials of BC patients and survivors as breast health educators sharing their lived experiences to empower and motivate women to act on health information on BC prevention and screening. Findings could guide the design of population-level interventions on BC prevention and screening.

The purpose of this study was to investigate the anti-wrinkle and skin- whitening efficacy of Rhododendron micranthum methanol extract (RMME) in a cell-free system. The total polyphenol and flavonoid contents of RMME were 280.42 mg/g and 197.31 mg/g, respectively. The electron-donating abilities of RMME and ascorbic acid were 96.2% and 98.0% at 1,000 μg/mL, respectively. The IC50 (50% inhibitory concentration) of collagenase activity for RMME and ascorbic acid were 128.6 μg/mL and 123.8 μg/mL, respectively. The IC50 of elastase activity for RMME and ascorbic acid were 232.1 μg/mL and greater than 1,000 μg/mL, respectively. The IC50 of mushroom tyrosinase activity for RMME and arbutin were 420.0 μg/mL and 474.9 μg/mL, respectively. These results indicate that RMME has high antioxidant capacity and excellent anti-wrinkle and skin whitening effects, which are similar to or even superior to ascorbic acid or arbutin in a cell-free system.


Background  Concepts of inclusion and participation are at the core of both international and Norwegian policy for people with intellectual disability. The aim of this study was to identify senior centre users' views of the barriers and solutions to the inclusion of seniors with intellectual disability in community senior centres.

Method  Thirty seniors without intellectual disability participated in one of four focus groups. The groups were recorded and transcribed verbatim. Data were analysed for themes using the constant comparative method of qualitative analysis.

Results  Major themes included benefits, perceptions of people with intellectual disability, barriers and solutions to inclusion, need for support and need for information.

Conclusions  The findings suggest that participants agreed that seniors with intellectual disability could benefit from being a senior centre user. Consideration must be given to this group's need for assistance, staff education, economic resources and ways to overcome negative community attitudes towards people with intellectual disability.

For a commutative semiring R with non-zero identity, the maximal graph of R, denoted by MG(R), is the graph whose vertices are all elements of UM(R) with two distinct vertices joined by an edge when there is a maximal co-ideal that contains both of them. In this paper, we study some properties of maximal graph such as planarity, radius, splitting and domination number.


Inflammatory Bowel Diseases (IBD), which include Crohn's disease and ulcerative colitis represent a group of incurable lifelong diseases affecting about 0.67% of the Canadian population (2012) and severely impacts the health‐related quality of life through ongoing debilitating symptoms like pain, gastrointestinal dysfunction as well as behavioral comorbidities like anxiety, depression, fatigue and cognitive impairment. Depression and anxiety are prevalent in individuals with IBD at a rate that outpaces the general population thereby substantially increasing the burden of the disease, as well as economic cost of managing it. Although clinical surveys and population studies have established a strong relation between IBD, depression and anxiety disorders, our knowledge of CNS changes is limited. We therefore investigated these comorbidities in a mice model of IBD with similarities to Ulcerative colitis, caused by administration of Dextran sulphate sodium (DSS) in drinking water for 5 days. In male and female mice, DSS treatment caused increased increased brain excitability, revealed by a decrease in seizure onset times after intraperitoneal administration of 25mg/kg body weight of Kainic acid; this was positively correlated with the intensity of inflammation only in males. Moreover, both sexes showed an increased anxiety‐related behavior on the elevated plus‐maze (EPM). We assessed pain levels, because they may influence behavioral response; only male mice were hyperalgesic when tested on the hotplate for thermal pain sensitivity indicating that altered behavioral responses cannot be entirely attributed to an interference with a movement brought about by pain. Further studies mapping the CNS pathways integral to the above changes will reveal novel mechanisms as to how peripheral inflammation results in changes in central immune‐mediated affective behaviors.


This study entitled "Determinants of vertical jump on football in Ethiopian youth sport academy" was designed to identify their vertical jump abilities. The population (N = 201, male =100 and female =101) was selected from Ethiopian Youth Sport Academy Football, whose ages ranged from 13 to 20 years. SPSS version 20.0 was employed to analyse multiple linear regressions with five predictor variables. Findings of the analysis show that sex is a strongest unique contributor and also age group has a significant effect on vertical jump. BMI ranges 19.1 to 21.72 kg/m2, percentage of body fat ranges 6.095 to 7.64 % for male & 13.08 to 14.42 % female, and the normal sum of skinfold is also in the range of enabling to improve jumping abilities. Therefore, these five variables are indeed different from each other and they affect the vertical jump (Y) in different manners.


AIM
Our study prospectively evaluated dental development in children exposed to chemotherapy in utero compared to unexposed controls.

DESIGN
Women who received chemotherapy while pregnant were enrolled in a research registry. After age two years, each child's dentist was asked to complete a questionnaire about dental abnormalities and malformations as well as for their unexposed siblings. Multivariate linear regression adjusting for age was used to compare the groups.

RESULTS
Dental information was received for 67 exposed children and 59 controls. The majority of mothers were treated for breast cancer (79.1%) and primarily received Doxorubicin (89.6%) and Cyclophosphamide (80.6%). Mean gestational age at first exposure was 20.7 (±5.7) weeks. Mean age at dental evaluation was 8.0 (±4.3) years for exposed and 10.4 (±5.1) years for controls (p < 0.01). Missing teeth, tooth size, shape, and color did not differ significantly between groups. There was no statistical difference in dental caries, facial abnormalities, or abnormalities of enamel or gingiva. There was no association between any chemotherapy agent or regimen and increased risk of dental abnormalities.

CONCLUSIONS
Overall, there was no difference in dental abnormalities between groups. These negative findings may be due to the fact that no one received chemotherapy prior to 14 weeks when formation of primary teeth was beginning.


Sorghum [Sorghum bicolor (L.} Moench] infected by sugarcane mosaic virus strain MDMV-B (SCMVMDMV-B) (formerly maize dwarf mosaic virus strain B) expresses variable symptoms depending on plant genotype and temperature. Infection causes a yellow to dark green pattern (mosaic), and a necrotic reaction (red-leaf) develops on certain genotypes when the temperature drops below 21 ·c (69 . F). Hybrids expressing the redleaf symptom show greater reduction in yield. Immunity to SCMV-MDMV-B is not present in commercially available hybrid sorghums.


Language is the material carrier of thinking, and the two are interdependent and inseparable. In the process of second language acquisition, learners' language thinking often has an important influence on the process and result of second language acquisition, primarily because native language thinking influences the verbal expression of the second language in daily life. Students in their native language environment and are influenced by their cultural practices develop specific native language thinking. They already have some background knowledge and cognitive comprehension of their native language in their minds before they try to learn a new language. Therefore, for them, the process of second language acquisition is not zero-based but takes the native language as the base. Moreover, because of the vast differences in grammar and expressions between English and Chinese, the casual nature of the spoken language, and the less rigorous grammatical requirements, English learners who use Chinese as their first language tend to apply their native language's habitual thinking to the use of English. Therefore, exploring the relationship between Chinese thinking and speaking is an integral part of the second language acquisition process. This paper explores the relationship between Chinese thinking and speaking, explores the influence of language thinking on speaking acquisition, and discusses how classroom teaching can help learners overcome the interference of fixed thought in Chinese and develop English thinking skills to improve learners' English-speaking performance.

The success of liver transplantation as the treatment of choice for many patients with liver failure has increased the demand for this therapy. The need for transplantable donor organs now exceeds the supply, and in many countries, wait-list mortality now greatly exceeds the 1year postoperative mortality. In an attempt to meet this increasing demand, liver transplant units are turning to the use of increasingly marginal donor organs. These include older donors, more obese donors, those with more medical comorbidities, and those from donors declared dead following cardiovascular rather than neurological criteria (donation after circulatory death [DCD]). At the same time, the incidence of liver disease has increased in many parts of the world, further increasing demand. The use of marginal donor organs is relatively low. For example, only 34% of livers from the highest-risk quartile of multiorgan donors in the United Kingdom result in a liver transplant. Increasing utilization of DCD and other high-risk donor sources is dependent on new technology to improve the condition of these high-risk organs and also to detect those organs that will not function satisfactorily after transplantation (viability assessment). Organ preservation is required, first, to preserve organs (to facilitate the logistics of transplantation and to minimize the effects of ischemia/reperfusion injury). Second, it should, ideally, provide the means for repair of injuries to the organ sustained immediately before or during the process of organ retrieval. Finally, preservation technology is needed to provide the means for viability assessment, to enable the nonviable organ to be excluded reliably before transplantation. Static cold storage has been the mainstay of organ preservation throughout the 50-year history of liver transplantation. Its advantages include ease-of-use, simplicity, and transportability. Its disadvantages include the lack of oxygen delivery, leading to accumulation of the metabolic products of anaerobic respiration, the lack of effective viability assessment, and direct cellular effects of cooling. Increasing evidence, though none yet from randomized controlled trials, suggests that hypothermic machine perfusion combined with the provision of oxygen has a beneficial effect on postreperfusion graft function and survival. Two trials are underway in Europe to investigate this formally. Normothermic perfusion attempts to recreate the physiological environment by delivering oxygen, physiological temperature, and nutrition. This allows aerobic metabolism to continue during the period of preservation, minimizes the effects of ischemia/reperfusion, and allows the viability of the organ to be assessed by measuring metabolic and synthetic parameters. The potential advantages of normothermic preservation were first shown in large animal experimental studies. It was shown at an early stage that it was possible to transplant livers successfully, not only with substantially prolonged periods of preservation (20 hours) but also with substantial hypoxic injury (40 minutes). These studies also provided evidence that biochemical and other perfusion parameters might be beneficial in determining which livers should be transplanted. In recent years, interest has increased around the world, and a number of commercially developed normothermic perfusion systems are undergoing clinical trials. Abbreviations: DCD, donation after circulatory death.


We have treated 33 humeral shaft fractures including 22 fresh fractures, 5 pathological fractures and 6 nonumions from 1992 to 1994 with a specially designed Hang-Lin (HL)nail which was a homogenous cylinder nail with 2 transfixation screws at both ends. The fresh fractures comprised 17 closed, 2 type I, 2type II and 1 type III open fractures. Bone comminution as AO classification was 9 type A, 8 type and 5 type C. The distribution of the fractures was 5 in proximal third, 10 in middle third and 7 in distal third. The medium duration of nonumion was 1.4 years. Six patients had 7 previous operations. The distribution of the nonunion was 2 in proximal third, 2 in middle third and 2 in distal third. The pathological fractures were caused by metastasis of lung cancer in 1, breast cancer in 3, and prostate cancer in on one. Antegrade nailing was performed in 13, and retrograde nailing in 20 cases. All of the fresh fractures and nonumions achieved solid union without infection. The average union time was 8.4 week for fresh fractures and 13.2 weeks for nonunions. All the patients with pathological fractures had good pain relief and functional recovery. There were no patients with limited shoulder joint or elbow joint motion except for one patient with a type IIIb open fracture. He had 0 to 100∘elbow motion after repeated soft tissue surgeries. One patient with distal fracture was complicated with 10∘varus malunion. Iatrogenic bony split occurred in 2 cases of retrograde nailing but the healing was not affected. Internal fixation with HL nails is worthy of recommendation in the operative fixation of humeral shaft fractures. Retrograde nailing was preferred if possible.


Establishment of plant communities occurs under the terms of climate and environmental conditions of the habitat and Environmental factors determine the characteristics of their habitat and have important role in plants distribution pattern. This study investigated the influence of topographic factors (elevation and aspect) on the distribution of medicinal plant Ferula gummosa case study Rangelands of Khombi and Saraii Germeh city in Khorasan shomali Province is situated at a distance of 128 kilometers of west Bojnourd city and 60 kilometers north of Jajarm. Following of determination of habitat Ferula gummosa and classification of the four classes of elevation 1600,1700,1800 and 1900 meter and 4 for the main geographical aspect its distribution in the 8.8-square-meter were investigated. The results show that elevation classes 1600 m with other elevation classes' is difference significant. Between the North and the other directions are also significant differences. So elevation and aspect with effects on the temperature and humidity are the main factors controlling the distribution of plant species.


Titanium dioxide nanotube (TNT) films were prepared by pulsed laser deposition (PLD) of P25 and P90 TiO2 nanoparticles onto stainless steel foils followed by a hydrothermal treatment (HT). Heating the PLD films in a TNT precursor solution at 150°C resulted in a well-adhered dense mat of TNTs that were ∼10 nm in diameter with a pore size of ∼4 nm. The TiO2 nanotube films were characterised by SEM, TEM, XRD and Raman spectroscopy.


【This research investigates the application of ZnO (zinc oxide) nanoparticles and $TiO_2$ (titanium dioxide) nanoparticles to polypropylene nonwoven fabrics via an electrospinning technique for the development of textile materials that can decompose harmful gases. To fabricate uniform ZnO nanocomposite fibers, two types of ZnO nanoparticles were applied. Colloidal $TiO_2$ nanoparticles were chosen to fabricate $TiO_2$ nano- composite fibers. ZnO/poly(vinyl alcohol) (PVA) and $TiO_2$ /PVA nanocomposite fibers were electrospun under a variety of conditions that include various feed rates, electric voltages, and capillary diameters. The morphology of electrospun nanocomposite fibers was examined with a field-emission scanning electron micro- scope and a transmission electron microscope. Decomposition efficiency of gaseous materials (formaldehyde, ammonia, toluene, benzene, nitrogen dioxide, sulfur dioxide) by nanocomposite fiber webs with 3wt% nano-particles (ZnO or $TiO_2$ ) and 7 $g/m^2$ web area density was assessed. This study shows that ZnO nanoparticles in colloid were more suitable for fabricating nanocomposite fibers in which nanoparticles are evenly dispersed than in powder. A heat treatment was applied to water-soluble PVA nanofiber webs in order to stabilize the electrospun nanocomposite fibrous structure against dissolution in water. ZnO/PVA and $TiO_2$ /PVA nanofiber webs exhibited a range of degradation efficiency for different types of gases. For nitrogen dioxide, the degradation efficiency was 92.2% for ZnO nanocomposite fiber web and 87% for $TiO_2$ nanocomposite fiber web after 20 hours of UV light irradiation. The results indicate that ZnO/PVA and $TiO_2$ /PVA nano- composite fiber webs have possible uses in functional textiles that can decompose harmful gases.】


In line with the increasing use of sensors and health application, there are huge efforts on processing of collected data to extract valuable information such as accelerometer data. This study will propose activity recognition model aim to detect the activities by employing ensemble of classifiers techniques using the Wireless Sensor Data Mining (WISDM). The model will recognize six activities namely walking, jogging, upstairs, downstairs, sitting, and standing. Many experiments are conducted to determine the best classifier combination for activity recognition. An improvement is observed in the performance when the classifiers are combined than when used individually. An ensemble model is built using AdaBoost in combination with decision tree algorithm C4.5. The model effectively enhances the performance with an accuracy level of 94.04 %.
