PurposeSmooth and autonomous navigation of mobile robot in a cluttered environment is the main purpose of proposed technique. That includes localization and path planning of mobile robot. These are important aspects of the mobile robot during autonomous navigation in any workspace. Navigation of mobile robots includes reaching the target from the start point by avoiding obstacles in a static or dynamic environment. Several techniques have already been proposed by the researchers concerning navigational problems of the mobile robot still no one confirms the navigating path is optimal.Design/methodology/approachTherefore, the modified grey wolf optimization (GWO) controller is designed for autonomous navigation, which is one of the intelligent techniques for autonomous navigation of wheeled mobile robot (WMR). GWO is a nature-inspired algorithm, which mainly mimics the social hierarchy and hunting behavior of wolf in nature. It is modified to define the optimal positions and better control over the robot. The motion from the source to target in the highly cluttered environment by negotiating obstacles. The controller is authenticated by the approach of V-REP simulation software platform coupled with real-time experiment in the laboratory by using Khepera-III robot.FindingsDuring experiments, it is observed that the proposed technique is much efficient in motion control and path planning as the robot reaches its target position without any collision during its movement. Further the simulation through V-REP and real-time experimental results are recorded and compared against each corresponding results, and it can be seen that the results have good agreement as the deviation in the results is approximately 5% which is an acceptable range of deviation in motion planning. Both the results such as path length and time taken to reach the target is recorded and shown in respective tables.Originality/valueAfter literature survey, it may be said that most of the approach is implemented on either mathematical convergence or in mobile robot, but real-time experimental authentication is not obtained. With a lack of clear evidence regarding use of MGWO (modified grey wolf optimization) controller for navigation of mobile robots in both the environment, such as in simulation platform and real-time experimental platforms, this work would serve as a guiding link for use of similar approaches in other forms of robots.


Starting from the integral forms of the equilibrium condition and the constitutive law over the small volumes centered at the nodes, this study approximates stresses and displacements independently by means of the meshless approximation. By interpreting the meshless approximation from a new perspective, the procedure does not need to differentiate the nodal shape functions. The stresses can be approximated as accurately as the displacements, even if the shape functions for the stresses and the displacements are both taken as those simple interpolation functions such as the Shepard functions. Besides, in general no background mesh is needed. Illustrated by some elastic–plastic problems, the procedure enjoys high efficiency and excellent numerical properties.

Background: Association of genetic-variants in the FADS1-FADS2-gene-cluster with fatty-acid-composition in blood of adultpopulations is well established. We analyze this genetic-association in two children-cohort-studies. In addition, the association between variants in the FADS-gene-cluster and blood-fatty-acid-composition with eczema was studied. Methods and Principal Findings: Data of two population-based-birth-cohorts in the Netherlands and Germany (KOALA, LISA) were pooled (n = 879) and analyzed by (logistic) regression regarding the mutual influence of single-nucleotidepolymorphisms (SNPs) in the FADS-gene-cluster (rs174545, rs174546, rs174556, rs174561, rs3834458), on polyunsaturated fatty acids (PUFA) in blood and parent-reported eczema until the age of 2 years. All SNPs were highly significantly associated with all PUFAs except for alpha-linolenic-acid and eicosapentaenoic-acid, also after correction for multiple-testing. All tested SNPs showed associations with eczema in the LISA-study, but not in the KOALA-study. None of the PUFAs was significantly associated with eczema neither in the pooled nor in the analyses stratified by study-cohort. Conclusions and Significance: PUFA-composition in young children's blood is under strong control of the FADS-genecluster. Inconsistent results were found for a link between these genetic-variants with eczema. PUFA in blood was not associated with eczema. Thus the hypothesis of an inflammatory-link between PUFA and eczema by the metabolic-pathway of LC-PUFAs as precursors for inflammatory prostaglandins and leukotrienes could not be confirmed by these data.

The aim of this paper is to investigate and analyse the safety and increasing accident rate problems in Kuwait. A review of relevant literature has been carried out, then a questionnaire has been piloted and implemented to collect data. The main survey was carried out in 2013. 810 distributed questionnaires resulted in the return of 430 completed questionnaires. Data is limited due to time constraints. RESULTS show that socio economic factors, attitudes and work commitment factors all contribute to the behaviour of road users in Kuwait. There is very little knowledge of modelling and analysing factors that affect drivers' behaviour towards safety in Kuwait. Keywords: Traffic safety in Kuwait, attitudes to road safety, socio economic characteristics, attitudinal surveys Language: en


Modern video streaming applications apply adaptive bitrate (ABR) algorithms to enhance user quality of experience (QoE). The existing model-based ABR algorithms failed to generalize to diverse network conditions and personalized QoE objectives due to their fixed control rules. The learning-based ABR algorithms required significant tuning to learn a well-performed model which can cause a QoE degradation during the model testing phase. In this paper, we propose FedABR, a novel ABR algorithm based on personalized federated learning to address the above challenges. To enable clients' local model dealing with network environment changes, we introduce a federated learning approach to train a global model using all the clients' local model without gathering their data together to protect clients' privacy. We also introduced an adaptation phase to train a personalized model for each client to maximize their individual QoE. By jointly training multiple learning tasks with a global model, it has the ability to provide transferable knowledge to supervise bitrate selection, and can be efficiently adapted to a new task in unseen environment with much fewer data samples and training epochs. We implement the proposed FedABR based on an emulation platform which connects to the Linux network protocol stack through a virtual network interface to send real data packets for evaluation. Extensive experiments based on real-world traces show that FedABR achieves the best comprehensive QoE compared with the state-of-the-art ABR algorithms in a variety of network environments.

Nowadays Image retrieval is becomes more challenged thing in many of the fields like medical diagnosis, crime prevention, military services, architectural and engineering design, geographical information, trade- mark matching, etc. So there is the necessitates of effectively retrieving relevant images when needed. Thus, content-based image retrieval systems (CBIR) have become very popular for browsing, searching and retrieving images from a large database of digital images. So in order to improve the retrieval accuracy, this paper will focus on to use content-based image retrieval systems with kmeans as the clustering algorithm and B+ tree for speeding up the retrieval process. For representing the images, we extract their feature vectors of images using Daubechies' wavelets. Then we introduced the Zernike moments in the retrieved images with the reference image by that we find out the variations of the images. After that by comparing the images using Zernike moments and find out the forgery between the images.

This document describes a solution to the Heterogeneous Error Response
Forking Problem (HERFP), a situation in which a UAC remains unaware of
elements that are responding to its INVITE with a 'repairable'
error response, because a forking proxy in the signalling path only
forwards what it considers the 'best' final response. This issue
may cause communication establishment to be delayed or even fail. To
address this issue this document proposes a new method [preliminarily
called 'FIX'] to be used by a forking proxy that detects a HERFP
to notify the UAC of a repairable error.


This paper presents non-linear mathematical model of a computer network with a part of wireless network. The article contains an analysis of the stability of the network based on TCP-DCR, which is a modification of the traditional TCP. Block diagram of the network model was converted to a form in order to investigate the D-stability using the method of the space of uncertain parameters. Robust D-stability is calculated for constant delays values.


The purpose of this study was to describe the characteristics of social support and the influencing factors on social support in nursing home environments. Observations and staff questionnaires from two central Florida nursing homes were used in this grounded theory study to answer the following questions: (1) How is social support manifested? and (2) What are influences on social support? Social support manifestations seemed predominantly superficial and did not appear to involve complex reciprocal relationships, however, when reciprocal resident tasks were observed, they appeared to have significant value and were sources of pride for the residents. Facility behaviors and policies required by governmental mandates appeared to result in significant resident dependency, a situation that mitigates against significant social support. Key Words: Social Support, Nursing Home, and Elderly ********** In the year 2040, 77 million Americans will be over the age of 65 (Stone, 1999). Since an estimated 1,465,000 people over the age of 65 occupied nursing homes on any given day in 1997 (Gabrel, 2000), a large number of this aging population will undoubtedly require some type of long-term care. Recognizing the generalized perception of substandard quality of life in nursing homes, the Institute of Medicine recommended in 1985 that residents should be cared for in such an environment as will promote maintenance or enhancement of their quality of life. (Uman et al., 2000, p. 167) Repeatedly researchers have reported on the health benefits resulting from social support (Cohen-Mansfield, 2000; Lee, 1985; Siebert & Mutran, 1999). According to Atchley (2000), social support consists of people we can count on to provide ongoing emotional support, affirmation, information, and assistance, especially in times of crisis. Interestingly, nowhere is the enormity of the impact of social support potentially more critical than in the institutionalized elderly. Purpose The purpose of this study was to identify the characteristics of social support and the influencing factors on social support in a nursing home environment. Analysis of the social support dynamics within these long-term care or nursing home settings, particularly the relationships between residents, and the meanings and characteristics of these relationships, as well as the influences on social support, may potentially contribute to increased holistic and resident-centered services and perhaps enhanced resident well-being. Literature Review Definition of Social Support Atchley's (2000) aforementioned definition of social support is a broad definition of social support. Other academic theoretic definitions add that the recipient should have a perception of someone caring for them and a resultant sense of well-being (Hupcey, 1998). Hupcey enumerated the factors required for social support as follows: (a) the act of providing a resource, (b) the recipient having a sense of being cared for or a sense of well-being, (c) the act having an implied positive outcome, (d) the existence of a relationship between the provider and the recipient, (e) support not given from or to an organization, the community, or a professional, and (f) support that does not have a negative intent or is given grudgingly. Given these constraints, it is unclear as to whether social support is present in cases of critically ill, incoherent recipients, in cases of negative outcomes in which either the recipient or provider perceive the support actions as positive, in support given from or to an organization, the community, or a professional, and in support that has a negative intent or is given grudgingly. In order for social support to yield maximum life satisfaction benefits, it must include the ingredient of reciprocity (Lee, 1985). Reciprocity involves mutual sharing or giving and helps to sustain self-worth. …


This paper deals with one type of Al faā120; Al faā Al-fa"ī$a that much found in Arabic. It tries to develop a framework for this faā, conceptually and functionally throughout answering two main questions: (1) what is the concept of Al faā Al-fa"ī$a? (2) What is the value of Al faā Al-fa"ī$a in the Arabic text? In the first part, the account provides a vision for the definition of this faā, the reason for calling it Al faā Al-fa"ī$a, its location among the Arabic faās, and its relationship with the other similar faās. In the second part, the research explores the functional roles of Al faā Alfa"ī$a in-text, throughout the application on the Qur'ānic text. It concludes that this faā has two main textual functions: cohesion and economy. In addition to some other various contextual functions. Key words: Al faā Al-fa"ī$a, the Qur'ān, economy, cohesion, text, context.


Ileo-colic Intussusception after Appendicectomy Ileo-colic intussusception following appendicectomy is a rare condition. Cleland (1953) reviewed the five recorded cases, and added a sixth. In a further case, here reported, the intussusception occurred within two weeks of operation for acute appendicitis. CASE REPORT A lance-corporal aged 19 was admitted to hospital on January 26, 1954, with a typical history of acute appendicitis. Appendicectomy was performed through a gridiron incision; the appendix, lying in the pelvic position, was acutely inflamed throughout the whole of its extent. The stump was invaginated with a purse-string suture, and the caecum and proximal part of the ascending colon were noticed to be abnormally mobile. Post-operative progress was satisfactory until the evening of the fourth day,.when he complained of a vague central abdominal pain, which recurred several times throughout the day. On the fifth day the pains became increasingly severe, were colicky in nature, and were localized to the left iliac fossa. He had developed anorexia and had not vomited. His bowels were opened normally twice early in the day; no mucus or blood was seen, but after the second bowel action he passed no flatus up to the time of his second operation. His general condition was good, pulse 80, and temperature 99° F. (37.20 C.). He had tenderness, with guarding, over the right half of the abdomen and normal gut sounds were heard. Rectal examination elicited tenderness high up in the pelvis. Urine examination showed no abnormality; his total white-cell count was 12,000 per c.cm., with 82% polymorphonuclear leucocytes; and a straight x-ray examination of the abdomen in the standing position revealed no conclusive abnormality. During the evening of the fifth day after operation his condition deteriorated. He began to vomit, and his pulse rate rose to 120 and his temperature to 100.20 F. (37.9° C.). The pains became less severe and less frequent. The tenderness and guarding had spread to the epigastrium and the left hypochondrium. No mass was palpable. Intestinal obstruction due to an intussusception was tentatively diagnosed and operation advised. Under anaesthesia an elongated mass lying transversely in the epigastrium could be felt. Laparotomy was performed through a right lower paramedian incision. There was an intussusception of the terminal 9 in. (23 cm.) of the ileum and the caecum into the ascending colon and transverse colon, almost to the splenic flexure. This was fairly easily reduced except for the caecum, which had formed the apex of the intussusception. The caecum was finally reduced manually, accompanied by a few small spurts of pus from the oedematous and inflamed site of the invaginated appendix stump. The caecum and the proximal part of the ascending colon were quite mobile and had a short mesentery. The site of the appendix stump was infected, with flakes of pus covering the serosa, but the wall of the caecum appeared quite viable. The capillary oozing was controlled with hot packs; the caecum was dusted with penicillin powder and replaced in the abdomen. The wound was closed in layers and the peritoneum drained. The patient was placed on a five-day course of intramuscular crystalline penicillin, 200,000 units six-hourly, and streptomycin, 0.5 g. twice a day. Intravenous infusion and gastric aspiration were continued for three days. On the third day after his second operation he was well enough to take fluids by mouth and to get up. He continued to make satisfactory progress, and by the tenth day was quite fit and awaiting his sick leave.


Summary

In this paper the power of the two-sample test of Wilcoxonfor Logistic shift alternatives is computed by using two approximations, based on the asymptotic Normality of the test statistic. The sample sizes considered are m = n = 6, m = n=10 and m = n = 15. These approximations are compared with the results of an experimental determination by Monte Carlo techniques.


The "Slippery Slope Framework" hypothesizes that (an individual's) tax compliance is determined by both the tax authority's powerfulness and its trustworthiness, and that the two dimensions moderate each other. By employing a within-country fixed effects analysis for 25 European countries, this paper tests the conjecture that a slippery slope exists also on the aggregate level. Results show that both trust and power are positively correlated with higher tax compliance. Trust and power also moderate each other: the lower trust, the greater the compliance-increasing impact of power. However, the positive effect decreases with increasing coercion. Strong deterrence policies may eventually damage tax compliance.

During the past decade, a significant amount of research has been conducted internationally with the aim of developing, implementing, and verifying "advanced analysis" methods suitable for non-linear analysis and design of steel frame structures.

Application of these methods permits comprehensive assessment of the actual failure modes and ultimate strengths of structural systems in practical design situations, without resort to simplified elastic methods of analysis and semi-empirical specification equations. Advanced analysis has the potential to extend the creativity of structural engineers and simplify the design process, while ensuring greater economy and more uniform safety with respect to the ultimate limit state.

The application of advanced analysis methods has previously been restricted to steel frames comprising only members with compact cross-sections that are not subject to the effects of local buckling. This precluded the use of advanced analysis from the design of steel frames comprising a significant proportion of the most commonly used Australian sections, which are non-compact and subject to the effects of local buckling. This thesis contains a detailed description of research conducted over the past three years in an attempt to extend the scope of advanced analysis by developing methods that include the effects of local buckling in a non-linear analysis formulation, suitable for practical design of steel frames comprising non-compact sections.

Two alternative concentrated plasticity formulations are presented in this thesis: the refined plastic hinge method and the pseudo plastic zone method. Both methods implicitly account for the effects of gradual cross-sectional yielding, longitudinal spread of plasticity, initial geometric imperfections, residual stresses, and local buckling. The accuracy and precision of the methods for the analysis of steel frames comprising non-compact sections has been established by comparison with a comprehensive range of analytical benchmark frame solutions. Both the refined plastic hinge and pseudo plastic zone methods are more accurate and precise than the conventional individual member design methods based on elastic analysis and specification equations. For example, the pseudo plastic zone method predicts the ultimate strength of the analytical benchmark frames with an average conservative error of less than one percent, and has an acceptable maximum unconservati_ve error of less than five percent. The pseudo plastic zone model can allow the design capacity to be increased by up to 30 percent for simple frames, mainly due to the consideration of inelastic redistribution. The benefits may be even more significant for complex frames with significant redundancy, which provides greater scope for inelastic redistribution.

The analytical benchmark frame solutions were obtained using a distributed plasticity shell finite element model. A detailed description of this model and the results of all the 120 benchmark analyses are provided. The model explicitly accounts for the effects of gradual cross-sectional yielding, longitudinal spread of plasticity, initial geometric imperfections, residual stresses, and local buckling. Its accuracy was verified by comparison with a variety of analytical solutions and the results of three large-scale experimental tests of steel frames comprising non-compact sections. A description of the experimental method and test results is also provided.


This study was conducted to evaluate the effect of Sikhe made by medicinal herb on the functional level of liver. Water extract Ⅰ(12.9% W/W) and Ⅱ(25.8% W/W) were obtained from medicinal materials: Caragana Sinica, Glycyrrhiza uralensis, Atractylodes rhizoma alba, Atractylodes rhizoma alba, Crataegus pinnatifida, Paeonia lactiflora Pasll., Hordeum vulgare Linne, Oryza sativa Linne, ginger, peer and jujube. Experimental groups were divided into the control diet group (C), high fat diet group (HF), high fat diet treated with 5% extract I group (HFEⅠ) and high fat diet treated with 5% extract Ⅱ group (HFE Ⅱ). In sensory evaluation, overall quality scores associated with color, aroma, flavor and taste were significantly higher in water extract Ⅱ than in water extract Ⅰ. After investigating functional and lipid levels of livers in rats, we found that the administration of water extract Ⅰ or water extract Ⅱ to the high fat diet group (HF) did not affect the gain of body weight but mildly reduced GOT or GPT activity in the high diet group. Moreover, administration of these medicinal herbal extracts significantly decreased the levels of total lipid, triglyceride and total cholesterol in the high fat diet group (HF). However, administration of these medicinal herbal extracts did not affect the level of phospholipid. In conclusion, as Sikhe made by medicinal herb slightly decreased the activity of GOT or GPT and amount of lipid in liver, prevention against high fat diet is thought to be important for liver protection.


Can Genetically Engineered and Organic Crops Coexist? Catherine Greene and Katherine Smith JEL classification: Q01; Q13; Q57 Over the last decade, American consumers fueled a fast-growing market for organic food and U.S. farmers flocked to genetically engineered (GE) varieties of several major U.S. crops. The potential for GE crop production to impose costs on organic production, via accidental pollination and other mechanisms, underscores the problem of coexistence between GE and organic crops. Here we review evidence that consumer demand has led to markets for products differentiated on some basis of GE status, and that maintaining the integrity of those differentiated product markets relies on interventions such as physical distancing or product segregation. Further, at present, the costs required to support the coexistence of all markets is borne disproportionately by producers and consumers of organic food in the United States.

ABSTRACT The novel β-lactamase gene blaCTX-M-116 was identified in a Proteus mirabilis nosocomial isolate recovered from the urine of a patient in Moscow in 2005. DNA sequence analysis showed blaCTX-M-116 to be a hybrid gene consisting of 5′ blaCTX-M-23 (nucleotides 1 to 278) and 3′ blaCTX-M-22 (nucleotides 286 to 876) moieties separated by an intervening putative site of recombination (GTTAAAT). A retrospective analysis of available blaCTX-M genes in the GenBank database revealed 19 blaCTX-M genes that display the same hybrid structure.


A. The title is designed to indicate those particular aspects of stochastic differential equations which will be considered here: these are almost equally valid when the manifold in question is ℝ n (although compactness is often a useful simplifying assumption). In fact one of the main themes here will be that stochastic differential equations, even on ℝ n , induce non-trivial differential-geometric structures and these structures are an important tool in analyzing the behaviour of the solutions of the s.d.e.


The measurement of the S‐wave ππ scattering lengths is a fundamental test of the validity of Chiral Perturbation Theory. We report on the final NA48/2 result, based on the full statistics data set of more than one million reconstructed Ke4± decays. From these events we have determined the decay form factors and ππ scattering lengths a00 and a02. The result is the currently most precise measurement of the scattering lengths and is in excellent agreement with the predictions of Chiral Perturbation Theory.


ABSTRACT In this article we describe a three-year study that was conducted in three phases to evaluate the feasibility of assessing digitized portfolios of student creative work for high-stakes purposes. The first two phases suggested that creative work could be digitized with adequate fidelity, and that students could submit their own work from schools to an online portfolio system. These portfolios were assessed using online tools to facilitate both an analytical and comparative judgment method of scoring, with the latter appearing to be the more reliable. In the final phase this approach was evaluated to facilitate moderation and professional learning of standards with rural teachers. The study showed that comparative judgment is a viable and reliable method for assessing digitized creative products and coupled with online communication systems provides an effective and efficient approach to scoring, moderation and teacher professional development, particularly in rural locations.


Under the too short arc scenario, the evolutionary-based algorithm has more potential than traditional methods in initial orbit determination. However, the underlying multimodal phenomenon in initial orbit determination is ignored by current works. In this paper, we propose a new enhanced differential evolution (DE) algorithm with multimodal property to study the angle-only IOD problem. Specifically, a coarse-to-fine convergence detector is implemented, based on the Boltzmann Entropy, to determine the evolutionary phase of the population, which lays the basis of the balance between the exploration and exploitation ability. A two-layer niching technique clusters the individuals to form promising niches after each convergence detected. The candidate optima from resulting niches are saved as supporting individuals into an external archive for diversifying the population, and a local search within the archive is performed to refine the solutions. In terms of performance validation, the proposed multimodal differential evolution algorithm is evaluated on the CEC2013 multimodal benchmark problems, and it achieved competitive results compared to 11 state-of-the-art algorithms, which present its capability of multimodal optimization. Moreover, several IOD experiments and analyses are carried out on three simulated scenarios of space-based observation. The findings show that, compared to traditional IOD approaches and EA-based IOD algorithms, the proposed algorithm is more successful at finding plausible solutions while improving IOD accuracy.


Two-dimensional (2D) nanomaterials such as metal-organic nanosheets (MONs) are exceptionally fascinating for electronics, photonics, optoelectronics, spintronics, and magnetism due to their enticing properties such as tuneable structures of ligands and metal complexes, intensify porosity and conductivity as well as successful facile fabrication of larger domains of the 2D materials. Owing to their unique qualities, such as intrinsic electronics and optical attributes, 2D materials have achieved tremendous breakthroughs in the direct applications of MONs. Based on recent research findings, MONs have been regarded as promising materials for surface functioning. At the same time, the intrinsic band structure and electronic properties may be rationally regulated via structural change, which can be the focal point of advanced materials design, processing, and progress. In this context, the potential to utilize different ligands and a vast number of coordinative atoms become important in designing 2D materials to address the tremendous needs of industry players. This review focuses on coordination nanosheets, which is a type of molecule-based nanosheets. The examples of coordination nanosheets are discussed in Section 1. In Section 2, surveys research on bottom-up coordination nanosheets synthesized through the liquid/liquid and gas/liquid interfacial reactions are discussed. Section 3 discusses the potential applications of coordination nanosheets in nanomaterial science. Overall, this review provides a useful source of information for researchers working on advancing 2D nanomaterials, particularly coordination nanosheets.


Introduction: The incidence of hip fracture continues to increase as the elderly population increases, as a result of the extension of the average life span. Intertrochanteric fractures have been treated successfully by various methods, and now we are in an era where functional rehabilitation of patients to their preinjury levels is of prime importance. Reconstruction-type proximal femoral nailing is one of the surgical techniques used to treat intertrochanteric fractures. This implant faces less criticism than the previous ones, but it also has its own disadvantages. Aim: To analyze the factors that affect the functional and radiological outcomes of unstable intertrochanteric fractures treated by proximal femoral nailing and to identify the factors responsible for an abnormal gait pattern after union in some patients. Materials and Method: Forty-two patients treated in our facility who were categorized as having unstable intertrochanteric fractures were followed up until radiological union was achieved and 16 patients who had abnormal gait patterns were further studied to find the factor responsible. Tip Apex Distance, lateral screw sliding/collapse, screw position in the neck, initial and final neck-shaft angles, quality of reduction by the modified Fogagnolo et al. criteria and functional outcomes based on Harris Hip Score were analyzed. Results: The average Harris Hip Score in our study was 83.8. Thirty-eight patients did not have any complications, but 16 our patients had abnormal gait patterns at the final follow-up. The reason for the abnormal gait pattern was secondary varus collapse caused by excessive lag screw sliding. Conclusion: The initial quality of reduction as recommended by Fogagnolo is the key factor to achieve a favorable outcome. Proximal femoral nail helps in early return to their preinjury status in most of the patients. It also prevents the varus collapse in unstable intertrochanteric fractures, given the screws are positioned ideally.


One important social problem is teenage pregnancies, estimated at around 15 million a year worldwide. Various alternatives to solve this problem have been proposed, among the emergency contraception.
Emergency contraception is understood as the use of drugs or different mechanisms to avoid pregnancy after a sporadic sexual relationship.
From an ethical point of view, the most interesting aspects to assess as far as emergency contraception is concerned are: a) its efficiency, b) its mechanism of action, c) its side effects and d) the social consequences of its use. This article assesses all these aspects.
It offers an efficiency of around 80%. As regards its mechanism of action, it is reasonable to affirm that it acts through an anti-implantation mechanism in a percentage no lower than 50%, and is therefore abortive. In relation to its side effects, approximately
50% of users suffer them, although they are not generally significant. Finally, it would appear that the establishment of emergency contraception has neither succeeded in reducing the number of teenage pregnancies nor the number of abortions. Therefore, it would not be incongruous to revise the projects devised to solve such problems. In this sense, those projects which include a section on sexuality education apparently obtain more positive results.


Bleomycin was compared with conventional cytotoxic drugs in the treatment of 70 patients with advanced squamous cell carcinoma; the primary deposit was in the head and neck in 50 patients and in the perineum or skin in 20. Thirty-four patients received bleomycin while 36 received other cytotoxic drugs. No significant difference was detected between the two groups either in the pro-portion showing tumour regression or in the survival rates. If bleomycin is to advance the treatment of squamous cell carcinoma it can be only in combination with other drugs or with radiotherapy. other agents. Various drug combinations, which include bleomycin, are currently being assessed, especially in the management of the lymphomas, and a second Medical Research Council trial to compare bleomycin and radiotherapy with radiotherapy alone for moderately advanced squamous cell carcinoma of mouth, pharynx, larynx, and oesophagus continues (further participation in this trial would be welcomed).


In this paper, we study how to optimize the data shuffle phase by leveraging the flow relationship in datacenter networks (DCNs). In most of the clustering computer frameworks, the completion of a transfer (a group of flows that can enable a computation stage to start or complete) is determined by the flow completing last, so that limiting the rate of other flows (not the last one) appropriately can save bandwidth without impacting the performance of any transfer. Furthermore, for the flows enter network late, more bandwidth can be assigned to them to accelerate the completion of the entire transfer. Based on these characteristics, we propose the flow chasing algorithm (FCA) to optimize the completion of the entire transfer. We implement FCA on a real testbed. By evaluation, we find that FCA can not only reduce the completion time of data transfer by 6.24% on average, but also accelerate the completion of data shuffle phase and entire job.


This paper represents a snapshot of generative design technology looking at what it is, how it works, how it's being used and why it's changing the way we design the next generation of things. Predominantly companies investing in this technology are looking for ways to help reduce component mass, improve the performance of their designs, minimize manufacturing process time and help them create new products that are suited to the next generation of customer who's concerned more than ever with customization and uniqueness. Through the course of this paper we'll look at a number of key technologies being developed in this field, with a particular focus on the optimised lattice and organic algorithmic structures both of which use Autodesk technology. An example, the Airbus Group, is used to illustrate innovative ways that manufacturers are applying these technologies to maintain product strength whilst reducing weight, improving performance and, ultimately, helping them to stay one step ahead of their competitors in industries that are rapidly developing and innovating.


The most important tax system reform characteristic of tax distribution system operated in 1994, and a tax system combined with the market economic system was set up. An obvious adjustment has been made based on tax burdens, tax categories, tax rate and tax right as the main tax system and a great success has been made. But meanwhile some problems appears with deepening market economy, publishing the supporting measures of economic reforms and new change of the consumer demand. These problems should be resolved as quickly as possbile.


Rat C‐6 glioma possesses a β‐adrenergic receptor which, when activated, raises intracellular levels of cyclic adenosine monophosphate (cAMP) in cultured C‐6 glioma cells. The present study shows that growth of C‐6 glioma is suppressed in rats treated with the β‐adrenergic agonist isoproterenol. Addition of papaverine, a cAMP phosphodiesterase inhibitor, to the treatment schedule augments this effect. Pharmacological agents that elevate intracellular cAMP levels may retard the growth of neural tumors in vivo.


Taxicity of oxygen species such as free radicals and H2O2 has been invoked to explain a number of degradative processes in plants, most involving photo-oxidation. Since catalase is a major protectant against accumulation and toxicity of H2O2, we examined alterations in catalase activity in several plant species (Pisum sativum L. cv. Greenfeast, Vigna radiata (L.) R. Wilcz, Cucumis sativus L. cv. Heinz Pickling, and Passiflora spp.) during chilling, and compared this change to change in H2O2 content. Catalase activity was reduced in a range of chilling sensitive and tolerant species by exposure to low temperature. This reduction in catalase activity correlated better with the onset of visible symptoms than with the treatment itself. Visible injury in turn was dependent on light and temperature differences. Hydrogen peroxide concentrations invariably decreased with low temperatures.

Reduction in catalase activity therefore does not necessarily imply accumulation of H2O2 to damaging levels. The absence of a clear inverse relationship between catalase activity and H2O2 concentration suggests the continued activity of other reactions that remove H2O2 and these may be important in the tolerance of plants to oxidative attack. Loss of catalase activity may result from the inability of damaged peroxisomal membranes to transport catalase precursors into the peroxisome.


To make effective use of version control systems like Git in teaching, teachers require tool support to manage student repositories. RepoBee (https://repobee.org) is a command line tool that assists teachers in creating repositories for students, batch cloning of student repositories, facilitating industry-inspired peer review, and much more. A powerful plugin system makes RepoBee flexible, allowing it to execute workflow-specific tasks such as running JUnit test cases on cloned student repositories, managing repositories created by GitHub Classroom, and extracting grades from grading issues on issue trackers. Also by way of the plugin system, RepoBee uniquely supports both the GitHub and GitLab platforms. In this demo, we shall demonstrate how teachers can apply RepoBee to manage student repositories. We shall first show the core features of student repository creation and cloning, and then how workflows can be customized with the plugin system. To cultivate interaction, participants will be able to suggest desirable features, which we then attempt to start developing plugins for. Finally, we shall conclude with an open discussion on tool support for version control in education and attempt to identify future directions.

In contrast, presuppositions were found in the pragmatic aspects of humor, which became one of the supporting aspects of forming a humor.


Food availability and security are basic human rights. Lack of attention to food security such as unhygienic food processing can cause health problems. National Food and Drug Agency stated that 27.92% of school children snacks contain hazardous substances ranging from physical, chemical and microbiological. The survey results of 36 primary schools in the Ngronggot District do not have the criteria for a healthy canteen, it causes the access of street frood are increase freely in the Primary School environment. Most of them didn't have a food production legacy from Health Office or National Food and Drug Agency. The purpose of this study was to determine the most dominant factors among other factors, namely environmental sanitation, sanitation equipment, food handler personal hygiene, the condition of food raw materials, the condition of food storage, and the condition of serving food to the presence of E. coli. This research was quantitative method, with cross sectional approach. The research sample was 48 samples with simple random sampling technique. The instrument used was observation sheets and laboratory test results. Data collection techniques used interviews, observations and laboratory tests. Statistical analysis used Multiple Logistic it is found that the most dominant variable among the other variables is food handler personal hygiene = 0.003. The presence of E. coli indicates microbial contamination in food which results in food borne illness. It is recommended to increase supervision in food processing to reduce bacterial contamination.

The oxidative damage to proximal tubular epithelial cells may lead to renal dysfunction. This research aimed to investigate antioxidant activity of the Sa-khan crude extract (SCE) and evaluated its effect on cell viability of proximal tubular epithelial cells. The total phenolic content of the SCE was determined using Folin-Ciocalteu method. The free radical scavenging activity of the SCE was investigated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. The effect of the SCE on HK-2 cells, the human proximal tubular epithelial cell line, was investigated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The SCE showed the total phenolic content of 17.35 ± 0.40 mg GAE/g extract. In addition, the SCE exhibited scavenging activity on DPPH (IC50 = 1.15+0.071 mg/mL). Moreover, eleven spots of antioxidant compounds were detected when the two-dimensional thin-layer chromatography combined with the DPPH spray technique was performed. Furthermore, the SCE at the concentration of 0.125 mg/mL could promote the proliferation of HK-2 cells over various durations. Together, these results indicate that the SCE may contain compound(s) with potential health benefits.
Keywords: Sa-khan, normal human proximal tubular epithelial cell, antioxidant activity

We analyze polar jets observed by the Large-Angle Spectrometric Coronagraph (LASCO) instrument aboard the Solar and Heliospheric Observatory. The events studied here are from 1997 March 24 and August 5. The main objective of our analysis is to determine whether the jets' motions are consistent with ballistic behavior. Although ballistic trajectories have some success in fitting the observed kinematic motions, there is substantial evidence that gravity alone is not regulating the movement of the jets. First of all, the August 5 events appear to exhibit slight accelerations rather than decelerations above 3 R☉. Second, all the events studied here have very similar velocities, suggesting that by the time the jets reach the LASCO field of view, the jets have been incorporated into the ambient solar wind. If this is the case, the jets could be very useful as tracers of the solar wind at low heights in the Sun's polar regions.


Abstract Arctic sea level pressure data from the period of the Arctic Ocean Buoy Program show a significant decrease in the annual mean. In every calendar month, the annual mean is lower in the second half of the 1979–1994 period than in the first. The changes of the annual means are larger in the central Arctic than anywhere else in the Northern Hemisphere. The decreases are largest and statistically significant in the autumn and winter. The annual anomalies became negative relative to the 16-yr mean in the 1980s and have been negative in every year since 1988. Correspondingly, the mean anticyclone in the Arctic pressure field has weakened and the vorticity of the gradient wind field over the central Arctic Ocean has become more positive than at any time in the past several decades. The pressure decrease, which has been compensated by pressure increases over the subpolar oceans, implies that the wind forcing of sea ice contains an enhanced cyclonic component relative to earlier decades.


SUMMARY The Land Use Act of Nigeria shifted ownership of land to the state. This ousted de jure tenure security in customarily owned land. This study exposes the tenure security perceptions of rural farmers and the challenges they face because of the nationalisation of land. It emphasises that customary land tenure system is still widely prevalent and socially accepted in Nigeria. Being a qualitative case study, it uses semi-structured key informant interviews and secondary information review as data collection methods. It begins by presenting the history of land tenure in Nigeria. It then uses a case study to assess tenure security perceptions and their rural development implications. It exposes the difficulties encountered by rural dwellers in their quest to formalising their customary land rights into full tradable land titles. It reveals major insecurity-generating tenurial trends caused by the nationalised land tenure system. It concludes that land tenure insecurity is one of Nigeria's rural development problems because it weakens the capacity of rural dwellers to transform their own society. Finally, it makes recommendations for improving land tenure security for the improved development of rural areas. The study contributes to on-going researches on identifying problem-generating structures in rural development in Nigeria.


Abstract The increasing utilization of nuclear energy will create new types of airborne waste problems. Creation of a "neighborhood" of multiple reactor sites (relatively) close together will require airborne budget calculations. In anticipation of these requirements meteorologists are extending their research into larger scales. Some of the new techniques for observation and calculation are presented. Included are radar tracking of tracers to distances of 100 miles, new fluorescent dye experiments, and new wind measuring techniques.


4H-Chromenes bearing a trifluoromethylated chiral quaternary carbon center are synthesized via a novel oxa-Michael—aldol cascade reaction between 2-trifluoroacetylphenols and alkynals.


For the past several years, addiction counselors across the country have been indoctrinated with the idea that addiction recovery is a timesustained process marked by multiple stages of change. Presentations on the Prochaska, Norcross, and DiClemente (1994) stages of change model and other developmental schema of recovery (e.g., Brown, 1985; Gorski, 1989; Klingemann, 1991) regularly grace the menus of addiction treatment conferences. These models portray the journey from addiction through recovery initiation to recovery maintenance in terms of incremental stages and steps spanning months and years. While these models have great clinical utility for the majority of clients of the addiction counselor, they obscure a less common style of addiction recovery that is not characterized by such time-dependent processes. These latter recoveries are the fruit of dramatic personal transformations of such overwhelming intensity and depth that, in the span of moments or hours, a life is cleaved into the categories of before and after, leaving a new self in a body once occupied by another. In this article, we will explore historical examples of such climactic recovery experiences and explore the clinical implications of such phenomena.


Introduction: Marriage has always been emphasized as the most important factor in achieving the emotional needs. The satisfaction of marital relationship decreases over time and among many couples. This study was carried out to compare the effectiveness of group counseling based on Gottman's theory and Glasser's choice theory on increasing satisfaction and decreasing marital conflicts among married women. Methods: This semi-experimental research was run with pre-test and post-test design with experimental (2 groups) and control group. The statistical sample consisted of 45 married women who had referred to the counseling and psychological services center in Bandar Abbas city to solve their marital problems during 2016. They were selected using purposive sampling method from the initial 75 volunteers and randomly replaced in two experimental groups (Gottman's theory and Glasser's choice theory experimental groups) and one control group. The data was collected through the Enrich marital satisfaction questionnaire andnmarital conflict questionnaire by Sanaie et al and were analyzed using SPSS 22 software. Statistical methods such as single- and multi-variable covariance analysis tests were used for data analysis. Results: The results showed that group counseling led to increase in marital satisfaction and decrease in marital conflicts in married women in the post-test, compared with the control group (P<0.01), but no significant difference was observed between the effectiveness of two approaches on marital satisfaction and conflicts (P<0.05). Conclusion: Group counseling based on two theories had significant effects on increasing the satisfaction and reduction of marital conflicts and can be used by the couple therapists.


The Darknet and Bitcoins have been widely utilized by those who wish to anonymously perform illegal activities in cyberspace. Restricted in many countries, gambling websites utilize Bitcoin payments that allow users to freely engage in illegal gambling activities with the absence of a formal capable guardian. Despite the urgency and limited knowledge available to law enforcement regarding this issue, few empirical studies have focused on illegal gambling websites. The current study attempts to examine the characteristics and operations of online gambling websites on both the Darknet and Surface Web, which allow Bitcoin payments. The findings suggest that both websites on the Surface Web and Darknet have similar and distinctive features that attract and encourage online users to engage in extensive illegal gambling activities and potentially other illegal activities as well. The study concludes with policy recommendations to remedy the issue of online gambling.


Numerical estimation of quantum channel capacity is an important problem both theoretically and practically. Oto et al. showed an effective approximation algorithm to compute a capacity of a one-qubit quantum channel. In this paper, we show an explicit upper bound for the error of their algorithm. The algorithm might be repeatedly used in the verification of a certain equation or inequality. The bound of the error we give is a criterion to decide when to stop that iteration, and eventually it can improve the performance of the whole process of the calculation.


Measurements of plasma flow damping have been made in the Helically Symmetric eXperiment [F. S. B. Anderson, A. F. Almagri, D. T. Anderson, P. G. Mathews, J. N. Talmadge, and J. L. Shohet, Fusion Technology 27, 273 (1995)] using a biased electrode to impulsively spin the plasma and Mach probes to measure the rotation. There is a distinct asymmetry between the spin-up when the bias is initiated and relaxation when the electrode current is broken. In each case, two time-scales are observed in the evolution of the plasma flow. These observations motivate the development of new neoclassical modeling techniques, including a new model where the fast increment of the electric field initiates the spin-up process. The flow in the quasisymmetric configuration rises more slowly and to a higher value than in a configuration with the quasisymmetry broken, and the rise time-scale is in reasonable agreement with the neoclassical spin-up model. The flows decay more slowly in the quasisymmetry configuration than in the co...


ABSTRACT In this article, we argue that there is a need to theorize the relationship between entrepreneurship and the political beyond the currently dominant neo-liberal and emancipatory narrative by turning to an onto-political conception of entrepreneurship based on the processes of entrepreneurial experimentation. In entrepreneurship studies, the relevance and the potential of experimentation for shaping new organizational realities has only been explored marginally. Through re-reading the thinking on 'experimental systems' by the science historian Hans-Jörg Rheinberger and connecting it to Annemarie Mol's notion of 'ontological politics', we develop a conceptual framework for entrepreneurial experimentation which we document with the illustration of an art enterprise. The framework that we propose focuses on the interwoven embodied, material and processual dynamics of entrepreneurial experimentation and reframes entrepreneurial world-making as a speculative process driven by material reconfigurations and bodily connections. As a consequence, we argue that this model is able to emphasize the intricate political dimension inscribed in processes of entrepreneurial experimentation through their onto-political force of reconfiguring systems of 'self-others-things'. Furthermore, the model highlights that this capacity of 'world-making' cannot be realized without articulating the tensions and resistances that entrepreneurial endeavours often need to navigate and negotiate while reconfiguring and challenging dominant socio-material orders.


The aim of the study was to describe the patterns of growth, body composition and physical fitness and health of children in the city of Presidente Figueiredo / AM, through a transversal approach using a battery of tests of motor performance and anthropometric measures. A sample of 894 subjects of both sexes aged from seven to 16 years, with 479 boys and 415 girls, duly enrolled in 2010 at the headquarters of the municipality of Presidente Figueiredo-AM. The results of anthropometric variables showed that girls are taller, heavier and had a higher accumulation of body fat than boys, and these indices considered similar to those that have been found in studies of national and international reference.Regarding the data of physical fitness tests related to health is observed that for flexibility girls showed higher levels of performance than boys. Regarding the variables of abdominal modified, the data indicate better performance of boys compared with girls. This information indicated that the boys probably move more than girls, featuring girls who show little motivation to practice regular physical activity.


The liner system is an important part of sanitary landfill, which plays a very important role in keeping contaminant separate from surrounding environment. Development of contaminant transport models of landfill liner is overviewed based on the interaction, i.e., thermodynamic, hydraulic, electric, chemical and mechanical effects between landfill liner and filled waste. It provides useful information to establish better model in accordance with the field condition. In the end, further issues that establish contaminant transport models of landfill liner need to be solved were put forward.


Representations Theory is used extensively in many of the physical sciences as every physical system has a symmetry group G. Various differential equations determine the vibration of a molecule, and the symmetry group of the molecule acts on the space of solutions of these equations. In this paper we use CH4 (methane) molecule, which has four hydrogen atoms at the corners of a regular tetrahedron, and a carbon atom at the center of the tetrahedron. The four hydrogen atoms in CH4 are permuted by the action of the symmetry group and this action fixes the carbon atom. At each of the 5 vertices, we assign three unit vectors, called the standard basis vectors in directions of the three edges which are joined to the vertex. The symmetry group G of the molecules permutes the 15 standard basis vectors, so we may regard Q15 as a GG By expressing Q15 as a direct sum of irreducible GG-modules, the problem of finding the normal modes of vibration is reduced to that of computing the eigenvectors of some small matrices.

A series of earlier OIES Comments has looked at the proposals for UK Electricity Market Reform from a national perspective – how effective will they be in promoting the low carbon investment needed to meet the government's climate change targets? This Comment looks at a different aspect – the European dimension. This has not received very much attention to date but could turn out to be important. The reforms have been designed around the UK's targets and the UK electricity market, but of course we are now operating in a wider European context where, with UK backing, the Commission has been promoting a single European market. Is it possible to introduce fundamental reforms within only one part of this wider market? This Comment explores some of the issues.


Electroosmosis is one of the processes that occurs when an electric current is applied through saturated fine grained soil. The process can be used for different purposes. A modification has been made to permeameter for applying electroosmis. By adding graphite electrodes to the inlet and outlet of the cells, it was possible to conduct electric current through the sample. The carried out tests were permeability tests, followed by electroosmotic treatment of the samples without applying any axial loading. Backpressure and cell pressures were used throughout the experiment. Two cells having the same samples were used. In the tests before the application of a current, the permeability was in the range of sensitive clay, almost quick, which is the type of samples provided. The electrical resistance of the soft clay proved to be too large for the used current source. Therefore, saline water was used instead of fresh water to reduce resistance. The first cell was connected to 13V power supply (i.e non-constant current) and provided with saline water while the second cell was only provided with saline water without any electric current. The results were confirmed to the expectations, where the electric current increased the flow in the first cell and resistance were reduced in both cells due to the addition of saline water. Electrosmosis contributed to almost 90% of the volume discharge in the first cell. Some challenges reduced the efficiency of the experiment such as gasses production, leakage, and loss of electric current in the system. Important recommendations from the experiment such as the importance of using a non-conducting fluid, oil for example, as a surrounding liquid for detection of any leakage and eliminating the possibility of current loss. Graphite electrodes performed well, but gasses production should be treated in early stages and further investigations on the effect of alternating polarity in reducing the process need to be explored.


Assessing the complicated relationship that Henry James had with Balzac, particularly with his presentation of history as primarily one of sordid struggles over the secret histories of money and sexual misconduct in post-Restoration France, this essay seeks to make visible James's own formulation of what constitutes the actual historic page. I contend that James fashioned much of his own writing around precisely what was blatantly present in Balzac, by allowing the Balzacian page of the underside of contemporary history to remain unwritten, evident only as a delicate architecture of avoidance that nevertheless speaks volumes.


This study looks at women's religious conviction as a form of political agency that can be both resistant and submissive. The narratives of the women in this study showed that women can be political within religious submission. These women who had been conditioned by the religious and political culture to accept and adopt a secondary role to men had found through blogging the ability to be politically expressive and authoritative. Blogging enabled them to challenge the gendered dichotomy of the private and public by allowing them to share and make significant their private experiences. This study on Muslim women bloggers contributes to the inclusive understanding of subject formation in feminist theories, indicating that women's religious convictions can lead to material political transformations.


Archetypal O-acetylation reactions of alcohols and carbohydrates proceed rapidly in high yield under mild conditions in a dicyanamide based ionic liquid, that is not only an effective solvent but also an active base catalyst.


This paper aims at maximizing the average spectral efficiency of a secondary link in a cognitive radio context, where both the primary and secondary users are equipped with the adaptive modulation and coding (AMC) capability. In the training phase, the fixed training power of the secondary user is selected such that the prescribed average spectral efficiency of the primary link is guaranteed. In the data transmission phase, the transmit power and the AMC mode of the secondary user are selected under the maximum packet error rate (PER) constraint of the primary user, as well as the average power and PER constraints of the secondary user. According to different kinds of primary-link information available to the secondary user, i.e., the transmission mode, the signal-to-interference-plus-noise ratio (SINR), and no information at all, three optimization problems that maximize the average spectral efficiency of the secondary user are formulated, respectively. Based on their optimal solutions, three AMC-based adaptive transmission strategies that are composed of both online and offline algorithms are proposed. Their performances are then evaluated by extensive simulation.


Intestinal invagination is a disease that is most commonly found in children from 3 months to 3 years old. Invagination has also been described as the intrauterine cause of intestinal atresia. Objective of the research: to demonstrate 3 clinical cases when intrauterine invagination caused congenital intestinal obstruction of the small intestine. The study describes the experience of surgical treatment of 3 patients with atresia of the small intestine type I and type IIIA due to intussusception that occurred during the prenatal period. Two patients underwent intestinal anastomosis using laparotomy. In one patient, the intestinal anastomosis was performed in a laparoscopic manner. The early and long-term results of operations are investigated. Successful surgical treatment of atresia of the small intestine due to intrauterine invagination was possible in all 3 patients. Two patients had type IIIA atresia (separation of segments with a V-shaped defect of the mesentery), one – type I (membranous form) of this anomaly. The gender composition of the patients is represented by 2 girls and 1 boy. The weight of patients was in the range of 1280–2800 grams. Surgical treatment for all patients was performed on the 2nd day of life. The duration of the operation ranged from 60 to 65 minutes. Start enteral nutrition was possible in the range from 2 to 3 days after surgery. Full enteral nutrition is restored within 5 to 8 days after surgery. In the early follow up period after surgery, there were no signs of failure of the anastomosis. During the observation of patients from 6 months to 1 year, there were no signs of impaired intestinal transit. Intrauterine invagination is a rare cause of intestinal atresia. This disease has a good prognosis provided timely intervention and the absence of associated abnormalities. Laparoscopy in an expert children's surgical center can be an alternative in the treatment of patients with jejuno-ileal atresia caused by intrauterine invagination.


The utility model discloses a reverse pedal mechanism capable of controlling an automobile and other vehicles and fundamentally avoiding the phenomenon that a driver treads on an accelerator by mistake according to a structural theory. The reverse pedal mechanism is completely on the contrary compared with a conventional accelerator pedal; according to the reverse pedal mechanism, acceleration is realized by lifting a foot, and de-acceleration is realized by treading downwards; the driver treads downwards again to start a brake after an idling position is reached during the de-acceleration; therefore, acceleration and braking are seamlessly associated; in the aspect of performance, the reverse pedal mechanism completely overturns the conventional accelerator pedal and a conventional brake pedal on a vehicle. The reverse pedal mechanism can be suitable for manual gear vehicles, automatic gear vehicles, electronic accelerator vehicles and wire pulling accelerator vehicles, and the driver drives the vehicle more easily and safely. The reverse pedal mechanism mainly comprises an auxiliary pedal, a pedal, a brake shaft, an acceleration spring and an excitation power source, wherein an often-open switch for controlling starting and stopping of the excitation power source is arranged on the pedal; when the excitation power source is started to work, the excitation power source can pull up the pedal by the acceleration spring to execute acceleration; when the excitation power source stops working, the pedal is automatically reset to the idling position; at the idling position, the pedal is treaded downwards continuously, and the braking function is executed; the pedal drives the brake shaft to rotate, and the brake shaft drives the auxiliary pedal to push a brake main pump mandril to execute braking.


Since sexual mate swinging came about in the fifties, a lot of research has been done on the subject. This research, however, seem to have come to an end in the eighties. This means that there is no current data on the matter, and the current state of affairs is also unknown. The goal of this study, namely to investigate the attitudes of married couples towards sexual mate swinging, has been reached by handing out questionnaires to residents of Bloemfontein. A total of 500 useable questionnaires were received back. The questionnaire consisted of an attitude scale as well as a biographical questionnaire. The influence of various variables, namely gender, age, church attendance and language on the attitudes of respondents towards sexual mate swinging was investigated. A factorial analysis of variance was used, as were several oneway analyses of variance. The results have shown that gender, church attendance and language had a significant influence on sexual mate swinging, while age was the only variable which had no significant influence. (

Summary form only given. Light measurements of the Balmer /spl beta/-line of a deuterium plasma on an IEC (inertial electrostatic confinement) device are used to investigate the ICC (inertial collisional compression) theory proposed by R.W. Bussard et al. (1992). These measurements also serve as an important benchmark for the computer simulation code PDS-1 (Plasma Device Spherical 1-dimensional). The light intensity shows a steady decrease following, as expected, the cross sectional values at low voltage ranges (< 40 kV). At higher voltages, however, an increase in the light intensity to neutron rate ratio has been observed. This may be attributed to the ICC effect, which predicts a nonlinear increase in light intensity measurement at higher core densities.


Human CD4+CD39+ regulatory T (Treg) cells hydrolyze exogenous adenosine triphosphate (ATP) and participate in immunosuppressive adenosine production. They contain two T‐cell subsets whose role in mediating suppression is not understood. Frequencies of both CD4+CD39+ subsets were evaluated in peripheral blood lymphocytes of 57 cancer patients and in tumor infiltrating lymphocytes (TILs) of 6 patients. CD4+CD39+ and CD4+CD39neg T cells isolated using immunobeads and cell sorting were cultured under various conditions. Their conversion into CD39+FOXP3+CD25+ or CD39+FOXnegCD25neg cells was monitored by multiparameter flow cytometry. Hydrolysis of exogenous ATP was measured in luminescence assays. Two CD4+CD39+ cell subsets differing in expression of CD25, FOXP3, CTLA‐4, CD121a, PD‐1, latency associated peptide (LAP), glycoprotein A repetitions predominant (GARP), and the cytokine profile accumulated with equal frequencies in the blood and tumor tissues of cancer patients. The frequency of both subsets was significantly increased in cancer. CD39 expression levels correlated with the subsets' ability to hydrolyze ATP. Conventional CD4+CD39neg T cells incubated with IL‐2 + TGF‐β expanded to generate CD4+CD39+FOXP3+ Treg cells, while CD4+CD39+FOXP3negCD25neg subset cells stimulated via the TCR and IL‐2 converted to FOXP3+CTLA4+CD25+ TGF‐β‐expressing Treg cells. Among CD4+CD39+ Treg cells, the CD4+CD39+FOXP3negCD25neg subset serves as a reservoir of cells able to convert to Treg cells upon activation by environmental signals.


Ag-bearing particles for use in water sterilization, comprising particles consisting of garnet or composed mainly of garnet and, borne on the surfaces thereof, silver. A preferred aspect of silver is such that as shown in an SEM photograph given as a representative figure, particulate agglomerates of silver in groups are continuously or discontinuously borne on the surfaces of garnet particles. Efficient production of these particles can be accomplished by an electroless plating process wherein garnet particles are immersed in a mixed solution consisting of a reducing solution having at leastany of potassium sodium tartrate, glucose and acetaldehyde as a reducing agent dissolved in water, mixed with an aqueous silver nitrate solution and an ammonia solution.


Fast key generation algorithms which can generate random sequences of varying atomic lengths and throughput are important for secure data communication. In this paper, we present a non-linear congruential method for generating high quality random numbers at flexible throughput rates of upto 66 Gbps, on a GPU platform. Each random number can have up to 4096 key bits. The method can be easily extended for implementation on hardware platforms like FPGAs and ASICs as well. Our key generator is comprised of N Linear Congruential Generators (LCGs) running in parallel; we have chosen N=4096 for the GPU implementation. The outputs of the LCGs are combined using N encoded majority functions. The encoded majority function used for any bit is changed in every generation iteration. In our GPU implementation of the Non-Linear Congruential Generator (GPU-NLCG), it is possible to alter the LCG functions on the fly by changing the primes periodically without interrupting the generation. Our GPU-NLCG can be used for high speed cryptographic key generation for rates up to 66 Gbps and can be easily integrated into multi-threaded applications in cryptography and Monte Carlo methods. The GPU-NLCG passes the NIST, Diehard and Dieharder battery of tests of randomness, which ensure the quality of our ciphers.

Purpose: Universal health care lacks support in the US. Explicit health benefits packages (HBPs) may improve support for UHC by heightening comprehensibility and increasing perceived equality through outlining the cost and scope of care. To test these hypotheses, we compared support for UHC after a HBP intervention, uninformative control, or ���standard' UHC messaging from the World Health Organization (WHO). Method: Study 1 (N=189) was a 2(pre-post)x3(condition) mixed-subjects design. Participants were randomly assigned to one of three conditions: 1) building an HBP exercise; 2) reviewing a pre-selected HBP; 3) completing an uninformative control exercise. Study 2 (N=412) was a 2(pre-post)x2(condition) mixed-subjects design with random assignment to either building an HBP or reading WHO pamphlets about UHC. HBP building used the ���Choosing Healthplans All Together��� (CHAT) simulation exercise where participants constructed their own HBP by allocating a limited set of resources to benefit ) and choosing scope of coverage (basic-to-high). Support for UHC was our primary outcome measure; perceived equality (i.e. is UHC seen as fair?) and comprehensibility (i.e. how easy is it to understand UHC?) were included as mediators. All items were measured both pre and post intervention using 0-100 slider-bar scales. In Study 2, we also included the Rasch Numeracy Scale and the Subjective Numeracy Scale as moderators. Results: In Study 1, both HBP interventions did not increase UHC support versus the control. In Study 2 there was no main effect of experimental condition on support for UHC; ps < .05. However, there was a significant interaction between experimental condition and objective numeracy. Greater objective numeracy predicted increased support for UHC in the ���active' versus the ���passive' intervention. Conversely, lower objective numeracy resulted in our ���passive' intervention increasing support for UHC more than our ���active' intervention. Support for UHC was mediateut not comprehensibility. Conclusions: Active (i.e., creating your own plan) and passive (i.e., reviewing a pre-selected plan) HBP interventions did not increase support for UHC. A more externally valid ���passive' intervention presenting WHO pamphlets about UHC did increase support for UHC. The two interventions appeared to function by highlighting the equity inherent in HBP. However, the ���active' intervention was only effective for participants with high objective numeracy. Given that 29 percent of American adults (approximately 73 million) have low numeracy, it is important to focus future research on alternative approaches that are less quantitati


A promising system of Generalized Inverse Discrete Fourier Transform Non-Orthogonal Frequency Division Multiplexing (GIDFT n-OFDM) system can fulfil the requirement of supporting higher data rate in Fifth Generation (5G) technology. However, this system experience High Peak to Average Power Ratio (PAPR) due to massive number of subcarriers signal is transmitted. In this paper, three types of usual PAPR reduction techniques were applied in GIDFT n-OFDM system which are Clipping, Partial transmit Transform (PTS) and Selective Mapping (SLM). The system performance is compared and evaluated using Complementary Cumulative Distribution Function (CCDF) plot. Simulation results show that SLM technique give significant reduction of PAPR 9 dB of the original performance.


Oxygen vacancy migration and lead vacancy hole trapping were identified in sputtered lead zirconate titanate thin film by thermally stimulated depolarization current measurement and charge-based deep level transient spectroscopy. The oxygen and lead vacancy were correlated to the first and second wave of resistance degradation, respectively, by the wafer-level process nonuniformity in both electric field polarities, which gives alternatives to process assessment. The concentration of both defects can be controlled by process variations, and the resulting resistance degradation can be modelled using Schottky-limited conduction and two independent defect contributions.


Using film and television shows as a language teaching tool has become a popular choice among language teachers, especially with English language. This paper attempts to explain how film and television is beneficial in the language learning process thus the ideas presented here are in order to help incorporate this method of teaching into the lessons of English language. The use of long feature films, television shows, and short film clips in the classroom can be used to motivate students by finding films or shows which they find interesting and entertaining, enhance their grammar, and even teach the culture of the English speaking world. This paper provides the insight into different research on the topic of feature film and television shows as a language learning aid, as well as providing some guidelines for future research. It is intended to provide teachers with some ideas for using video in combination with course books, and it contains a variety of suggestions for activities to use in the ESL classroom in Bosnia and Herzegovina, but also in other countries where English is not the native language.


ABSTRACT Petroleum hydrocarbons, including alkanes ranging from C10 to C32, have been recognized as priority organic water contaminants with a toxic impact on ecosystems. Therefore, the removal of these contaminants is of utmost importance to protect humans, plants and animals. In this work, biochar derived from the dead leaves of the widely-distributed seagrass Halodule uninervis (SGC) was prepared through biomass pyrolysis at 800°C and characterized using SEM, FTIR, TGA and surface area analysis. The prepared SGC was investigated for adsorptive removal of total petroleum hydrocarbons (TPHs) and individual alkane hydrocarbons (C10 to C32) from water contaminated with crude oil. The SGC displayed good removal efficiency, adsorption capacity and recyclability toward these hydrocarbons. Using the SGC, 98.8% of the TPHs were removed within 300 minutes with an adsorption capacity of 23.5 mg/g. The adsorption results were tested with the most commonly used isotherm and kinetics models. The hydrocarbon adsorption data for the SGC fit the Langmuir and Freundlich isotherms, which indicates non-uniformity of the adsorbent and a predominance of multilayer adsorption of the hydrocarbons onto the prepared SGC adsorbent. The performance and reusability of the prepared SGC adsorbent were promising, losing only 22% of its hydrocarbon removal efficiency after the 3rd cycle. Graphical Abstract

AIM: To study the expression of matrix metalloproteinase-9 (MMP-9) in human bronchial epithelial cell treated with TNF-α, ConA and mechanical injury. METHODS: RT-PCR and gelatin zymography were performed to observe the dynamic expression of matrix metalloproteinase-9(MMP-9) in human bronchial epithelial cell line H292 at different timepoint(2 h, 6 h,12 h, 24 h) after stimulation with TNF-α, ConA and mechanical injury. RESULTS: Human bronchial epithelial cell H292 expressed and secreted matrix metalloproteinase-9 in the presence of TNF-α, ConA and mechanical injury. On stimulation with mechanical injury alone, MMP-9 was initially expressed at 2 h, peaked at 12 h, and decreased at 24 h. Furthermore, on stimulation with combination of ConA and mechanical injury, the MMP-9 mRNA expression was the highest among in all the groups. Zymography show that the MMP-9 activity appeared just at 24 h timepoint, and was highest at the group of combination of ConA and mechanical injury. CONCLUTION: Human bronchial epithelial cell expressed and secreted MMP-9 when treated with TNF-α, ConA and mechanical injury.

D EBATES ON THE NATIONAL INTEREST proceed from two perspectives. One tends to be policy oriented; the other, ethically oriented. Though these two perspectives overlap in the blurred double-vision of real choice in real situations, there is purpose in sorting them out. The national interest as it bears on policy represents a rough guide to, and a negative restraint on, decision and action. It defines the outermost limits of choice, beyond which responsible statesmanship must not trespass because to do so risks the security, perhaps the survival, of the nation. Exactly where this boundary line runs, and precisely what programs are to be pursued within its limits, are matters of constant debate among the many surveyors of the nation's interests. This is because "security" and "survival" (or "vital interest," or "way of life" or "national welfare") are not fixed points on the political terrain; rather, their precise location, their size and importance and relation to one another, depend in great part on the lens settings in the instruments by which they are surveyed. Thus the Chamber of Commerce defines the boundary circumscribing legitimate choice differently from the Pentagon, the Pentagon defines it differently from the State Department, and the State Department differently from the Atomic Energy Commission. The second perspective provides the subject for the present study, that is, the national interest as a problem in political ethics. It is the problem of reconciling necessity and principle: the necessity is that of protecting the interests of the group for which one serves as trustee and the principle is that of undifferentiated loyalty to values such as justice and equality. It is the problem of adjusting the moral claims laid upon one by his allegiance to the national community with the claims that derive from his loyalty to communities transcending the national community. It is the problem of dealing both realistically and creatively with self-interest, and nowhere is self-interest more stubbornly institutionalized, yet capable of


The article presents the results of the research on the production of knowledge about the "education policy in Brazil at the interface with Social Work", carried out from texts published in the Proceedings of the events: Brazilian Congress of Social Assistants (CBAS) and at the Meeting National Researchers in Social Work (ENPESS), considering the significant increase in production on the subject in recent years. An analysis was carried out on the works published in the annals of the CBAS edition of 2013 and 2016 and of ENPESS in the editions of 2014, 2016 and 2018. It was found that there is a greater number of works with theoretical density in those presented in CBAS than in ENPESS . The themes infrequency and / or school dropout, school-family relationship and medicalization of children and adolescents, appear with more incidence, coincide with the main requests made to social workers in the area of "‹"‹education.


A novel fast and accurate full-wave approach to the analysis of a wide class of slotted waveguide arrays is presented. The numerical-analytical solution is based on Galerkin method with weighted Chebyshev polynomials as basis functions explicitly accounting for the field asymptotic at the edges. A dramatically fast convergence of the method is achieved due to proper basis functions. The second key point of the solution is the acceleration of double series and integrals which are the matrix elements of a final system of linear algebraic equations. The comparison of results with available experimental and theoretical data shows a good agreement. The results for travelling-wave array with 120 shunt slots for radar applications are considered.
