In this paper we use the exogeneity techniques developed by Engle and Hendry (Journal of Econometrics, 1993, 56, pp. 119-39) and data from three Asian NICs to test the invariance assumption of the export-led growth hypothesis.


The reliability of the cutting tool is a key factor in accomplishing the objective of the machining processes. The methods and learning techniques to predict the tool life have been studied for several decades on basic machine tools, including milling, turning, and also drilling as a part of a smart manufacturing system. The current state of the cutting tool is used for modeling the tool's life. The undesired condition throughout machining, such as excessive vibration, will affect the tool life directly due to the tool failure, including chatter, wear, and breakage. The prediction of tool life using Tool Condition Monitoring Systems (TCMS) is fundamental for manufacturing productivity and also cost-effectiveness. It is implemented by using advanced sensors for data acquisition and determining the process parameters as well as vibration, sound, and cutting force are collected, either directly or indirectly. Signal processing methods and Artificial Intelligent (AI) classifiers are used to obtain the current state of cutting tools during machining processes. This paper reviews various methods and learning techniques of TCMS in predicting the tool life for different machining processes. An experimental tool life prediction was performed by using K-mer signal recognition as feature extraction for sound signal data collected by the microphone for the CNC turning process on alloy steel. Then, Support Vector Machine (SVM) is used to show the accuracy of the method. The experimental results have shown that it is feasible to apply K-mer signal recognition as feature extraction and SVM as machine learning to predict the tool life with 95% accuracy.


A new type of fluorine‐containing polybenzimidazole, namely poly(2,2′‐(2,2′‐bis(trifluoromethyl)‐4,4′‐biphenylene)‐5,5′‐bibenzimidazole) (BTBP‐PBI), was developed as a candidate for proton‐conducting membranes in fuel cells. Polymerization conditions were experimentally investigated to achieve high molecular weight polymers with an inherent viscosity (IV) up to 1.60 dl g–1. The introduction of the highly twisted 2,2′‐disubstituted biphenyl moiety into the polymer backbone suppressed the polymer chain packing efficiency and improved polymer solubility in certain polar organic solvents. The polymer also exhibited excellent thermal and oxidative stability. Phosphoric acid (PA)‐doped BTBP‐PBI membranes were prepared by the conventional acid imbibing procedure and their corresponding properties such as mechanical properties and proton conductivity were carefully studied. The maximum membrane proton conductivity was approximately 0.02 S cm–1 at 180 °C with a PA doping level of 7.08 PA/RU. The fuel cell performance of BTBP‐PBI membranes was also evaluated in membrane electrode assemblies (MEA) in single cells at elevated temperatures. The testing results showed reliable performance at 180 °C and confirmed the material as a candidate for high‐temperature polymer electrolyte membrane fuel cell (PEMFC) applications.

Brain 18F-FDG PET images are commonly-known materials for effectively predicting Alzheimer's disease (AD). However, the data volume of PET is usually insufficient, which is unfavorable to train an accurate AD prediction networks. Furthermore, the PET image is noisy with low signal-to-noise ratio, and simultaneously the feature (metabolic abnormality) used for predicting AD in PET image is not always obvious. Therefore, a contrastive-based learning method is proposed to address the challenges of PET image inherently possessed. Firstly, the slices of 3D PET image are amplified by cropping the image of anchors (i.e., an augmented version of the same image) to generate extended training data. Meanwhile, contrastive loss is adopted to enlarge inter-class feature distances and reduce intra-class feature differences using subject fuzzy labels as supervised information. Secondly, we construct a double convolutional hybrid attention module to enhance the network to learn different perceptual domains where two convolutional layers with different convolutional kernels ($7\times 7$ and $5\times 5$) are constructed. Moreover, we recommend a diagnosis mechanism by analyzing the consistency of predicted result for PET slices alone with clinical neuropsychological assessment to achieve a better AD diagnosis. The experimental results show that the proposed method outperforms the state-of-the-arts for brain 18F-FDG PET images, and hence demonstrate the advantage of the method in effectively predicting AD.


Worldwide, more than 1.25 million people die annually in road traffic accidents and between 20 and 50 million more are injured. By 2030, highway-related crashes are projected to be the 5th leading cause of death in the world. Road accidents have a number of contributing factors, including roadway conditions, vehicle conditions, and factors related to the road users. While some of these factors have been studied extensively by researchers very few focused on quantifying the relationship between accidents frequency and pavement quality. Before 1990s, due to the lack of pavement data collection technology, it was very difficult to carry out state-wide scale studies relating pavement quality and road safety. However, in the past decades, there has been a huge growth and awareness in the importance of road safety as a public health issue, leading to a significant increase of research in the topic. Researchers started to study other contributing factors to accidents occurrence such as the pavements quality. Moreover, with the development of high-speed friction measurement tools, agencies can now include friction into network level Pavement Management Systems (PMSs). Therefore, incorporating safety concerns is one of the urgent needs of PMSs, not only in order to optimize the management of the resources but also, and above all, towards the reduction of road fatalities. Despite the fact that there is limited research on the topic, important results were already achieved proving that there is a correlation between the frequency of traffic accidents and variables, which state the condition of the pavement such as friction, macrotexture and microtexture. This article aims to present a short review of the existing literature in Accident Frequency Prediction Models and Modelling Techniques already used or that can be used in PMSs. Moreover, the most interesting Accident Frequency Prediction Models for inclusion in PMSs will be tested with real data provided by a Portuguese Road Agency. The final part of the paper contains the conclusions and presents how these models can be incorporated in PMSs.

The radiometric subsystem of NASA's LANDSAT-4 Thematic Mapper (TM) sensor is described. Special emphasis is placed on the internal calibrator (IC) pulse shapes and timing cycle. The procedures for the absolute radiometric calibration of the TM channels with a 122-centimeter integrating sphere and the transfer of radiometric calibration from the channels to the IC are reviewed. The use of the IC to calibrate TM data in the ground processing system consists of pulse integration, pulse averaging, IC state identification, linear regression analysis, and histogram equalization. An overview of the SCROUNGE-era (before August 1983) method is presented. Procedural differences between SCROUNGE and the TIPS-era (after July 1983) and the implications of these differences are discussed.

AbstractThe Analytical Hierarchy Process (AHP) idealistically assumes the independence of the criteria which are often interrelated, conflicting or can be traded-off. It is, therefore, proposed that AHP could be extended by applying fuzzy logic to adequately incorporate the different relationships that may exist among the criteria. It is shown that the conventional and consistent fuzzy approaches could actually lead to different choices and an explanation is provided. Finally, two different application scenarios are illustrated on the web service selection problem.


Ascon has been selected as the rst choice for resource-constrained environments by CAESAR. Ascon-128 and Ascon-128a were also submitted to NIST's call for lightweight cryptography. The submission to NIST has been complemented with hashing functionality based on the well-studied permutation of Ascon and the sponge construction. In this note, we will give an overview of the existing analysis of the Ascon cipher suite and discuss the performance of Ascon in both software and hardware. Highlights. The Ascon suite supports authenticated encryption and hashing with the same lightweight permutation. It achieves high security and robustness in practice with a very low area footprint in hardware, while providing good performance in both software and hardware implementations, in particular for short messages. Cryptographic primitives that operate e ciently on resource-constrained devices, on modern high-end systems, and also in the area between these two extremes are of rising importance. A typical example of such environments is the Internet of Things (IoT), where a large number of very constrained devices need to communicate e ciently with high-performance back-end servers. In the following, we discuss the security and performance of Ascon in more detail and show why the cipher suite is a perfect t for such applications. Security. Ascon-128 and Ascon-128a have been selected as the primary choice for lightweight authenticated encryption in the nal portfolio of the CAESAR competition after ve years of evaluation. During this competition, Ascon and its permutation have undergone a thorough public analysis. So far, this has resulted in numerous publications that give insight into the security of Ascon and in a total of almost 100 publications that discuss Ascon more generally. All existing analysis con rms a comfortable security margin for Ascon. An overview of the best-known analysis of the authenticated encryption schemes is summarized in Table 1.

Aim: To study the correlation between integrity of the photoreceptor layer after resolution of macular oedema (MO) associated with branch retinal vein occlusion (BRVO) and final visual acuity (VA), and to determine prognostic factors for visual outcome. Methods: We retrospectively studied 46 eyes from 46 patients with resolved MO secondary to BRVO, the foveal thickness of which was less than 250 µm at final observation. We assessed the status of the third high reflectance band (HRB) in the fovea using optical coherence tomography (OCT) at final observation, and studied OCT images taken at the initial visit in the hope of identifying a factor that would be prognostic of visual outcome. Results: No differences were found in initial VA or in foveal thickness between eyes with or without complete third HRB at final observation. However, final VA in eyes without a complete HRB was significantly poorer (p<0.002). Additionally, initial status of the third HRB in the parafoveal area of unaffected retina was associated with final VA; lack of visualisation of the third HRB at 500 µm (p = 0.0104) or 1000 µm (p = 0.0167) from the fovea on initial OCT images was associated with poor visual recovery after resolution of the MO. Conclusion: Integrity of the photoreceptor layer in the fovea is associated with VA in resolved MO, and status of the third HRB before treatment might be predictive of visual outcome.


Article is an attempt to approximate the anthropological interpretation of Pamplona's bull run (encierro) in Spain. Article is based on two main aspects related to the traditions of bullfights: "Carmen" by Georges Bizet and Basque topic. Based on the analysis of the texts and my own field research I would like to reflect on whether encierros can be regarded as a theatrical spectacle. For this purpose I will try to indicate the proper theater criteria and ascertain whether they occur in relation to encierros and corrida de toros as well.


I warmly thank Caroline Traube and Nicolas Donin for offering me the opportunity to add a note to collective reflection on a subject which has greatly occupied my attention: the process of musical creation. Indeed, from the first years in which I was in charge of research in the sciences de la musique at the Groupe de Recherches Musicales (GRM, Paris), I spearheaded or encouraged analysis not only of musics themselves, but also of the way in which they are conceived, carried out, and then listened to (see Delalande, 2013, for an overview of this research program). Examining the process of creation over a period of time and in a given place – the GRM where music is made with machines – also meant delving into the question of artistic cooperation among different "professions": the composer of course (it is toward her/him that everyone would turn whenever the question of creativity was involved), but also instrumentalists, scholars, technical and computer assistants, and furthermore, instrument makers, bound up in the creative process. These profiles come into play in this special issue of Musicae Scientiae, but also a question: how are we to give an account of their cooperation? Actually this concern is not all that new, and this is what I would like to set forth within the following historical perspective, grounded partly in my own experience as a researcher and member of the GRM. Over a long period, throughout the time when the technology of writing dominated the composition of Western erudite music – roughly since the 13th century – creation was an eminently solitary activity, which had not been the case within the oral tradition (since creation in the oral context comes about in the very course of transmission); nor is it any longer solitary now whenever it occurs in the research institutions where highly different profiles rub shoulders and cooperate with each other. What actually is musical research? The answer is teams, locations, institutions wherein composers of experimental music are in a relationship of compelled cooperation, whether direct or indirect, with the inventors of technical tools. The full span of these practices is exercised under the watchful eye of a third pillar of musical research; that is, a reflexive, analytical research element (Delalande, 1986).1 Schaeffer was not wrong to boast of being the "creator of impossible but necessary institutions," as much as he was the inventor of musique concrète.2


Nanoparticles have outstanding properties due to their small size. Their high surface-to-volume ratio facilitate them a better interaction with biomolecules. Metal oxide nanomaterials like CuO, Ag and ZnO have been in frequent use for several purposes. Their inherent ability and surface chemistry make them suitable for the antimicrobial agent against pathogens. In this regard, the present study focuses on the synthesis and antibacterial activity of ZnO-NPs against Enterotoxigenic Escherichia coli (ETEC). Synthesis of ZnO-NPs was achieved by chemical method followed by capping of citrate. This allowed the particles to be separate and monodispersed. After characterization, the synthesized ZnO-NPs were tested as antibacterial agent against ETEC. The time dependent growth inhibition was also performed. The synthesized ZnO-NPs were highly effective and showed bactericidal activity after 16 hours. The present study offers ZnO-NPs as a potential antimicrobial agent which can be used against ETEC.


Objective To compare the effects of three preoperative skin preparation methods for orthopedic surgery on the skin coenobium count. Method 180 patients who received selective orthopedic implantation surgery during January to December, 2012, were divided into three groups with different detergents. Group A: soft soap solution; Group B: soft soap solution and 5% PVP-I; Group C: 75% ethanol and 5% PVP-I. Results After skin preparation, the comparison between three groups before surgery disinfection was conducted. Statistically significant difference was found between group A and group B as well as group A and group C, but no statistical significant difference was found between group C and group B. Conclusion The time when the notice of transferring patient for surgery by telephone from the surgery room is the best time for skin preparation. Besides, the less duration from the skin preparation with 5% PVP-I combined with soft soap solution or 75% ethanol to the surgery, the less number of bacteria and the longer duration of clean skin surface. The method mentioned above can meet the stringent requirements of orthopedic skin preparation and is worthy of recommendation.

Background: Breast cancer is considered a chronic disease owing to the increases in survival rate. Thus, better body image and patient satisfaction with the surgery have become more important factors to be considered when choosing the surgical approach. The aim of this study was to compare body image and patient satisfaction following three different approaches.
Methods: We evaluated 183 consecutive patients who had undergone three different surgeries including breast-conserving surgery (BCS), mastectomy, or mastectomy followed by reconstruction (M-R). Body image was evaluated using the BICI questionnaire, and patient satisfaction was rated using a multiple-choice question and a scale ranging from 1 to 10.
Results: A significantly better body image was observed in the M-R and BCS groups compared with mastectomy (P = 0.02). In body image subscale analysis, social functioning scores were higher in the M-R and BCS groups than in the mastectomy group (P = 0.01), but no differences were obtained between surgery groups in appearance dissatisfaction subscale. Patients were more satisfied with BCS than the other two surgeries (P = 0.008).
Conclusion: Based on the results of this study, it could be proposed that both oncoplastic BCS and implant reconstruction could provide patients with acceptable body image, while BCS could bring about better satisfaction with the surgery. Reconstruction may be an alternative for the patients to improve body image and satisfaction when BCS is not applicable.

In this paper we study a fundamental open problem in the area of probabilistic checkable proofs: What is the smallest s such that In the language of hardness of approximation, this problem is equivalent to determining the smallest s such that getting an s -approximation for satisfiable 3-bit constraint satisfaction problems ("3-CSPs") is NP-hard. The previous best upper bound and lower bound for s are 20 / 27 + ǫ by Khot and Saket [19] and 5 / 8 by Zwick [29]. In this paper we close the gap assuming Khot's d -to-1 Conjecture [15]. Formally, we prove that if Khot's d -to-1 Conjecture holds for any finite constant integer d , then NP ⊆ naPCP 1 , 5 / 8+ ǫ [ O (log n ) , 3] for any constant ǫ > 0. Our conditional result also solves H˚astad's open question [12] on determining the inapproximability of satisfiable Max- NTW ("Not Two") instances and confirms Zwick's conjecture [29] that the 5/8-approximation algorithm for satisfiable 3-CSPs is optimal.

Although it seems plausible that people who prefer a particular genre would appreciate characters from that category more than those from other genres, this appears not to be the case. We devised a parsimonious reality-based genre taxonomy that differentiates nonfiction, realism, fantasy, and humor. In Study 1, evidence from film viewers' genre preferences prompted slight adjustments in that taxonomy. In Study 2, however, we found that their reality-based genre preferences did not predict personal involvement with, distance from, or liking for the protagonist in the preferred genre. Instead, the represented and, particularly, the perceived realism of the character did affect personal involvement, but irrespective of genre preferences. We discuss the implications of these results for the rationale behind a genre typology and for engaging with fictional characters to explain personal involvement and character appreciation, especially in motion pictures.


One of the most challenging issues that man has been confronted with is human identification.1 Identifying identity is a fundamental process in Legal Medicine, both in civil and criminal terms2,3 being a prerequisite for the certification of death as well as for personal, social and legal reasons.4,5 Dactyloscopy (evaluation of fingerprints), dental records and deoxyribonucleic acid (DNA) are the most common techniques used, allowing the rapid and secure identification process. However, in certain circumstances, related to the crime scene or lack of experienced personnel, these techniques may not be available. Therefore, there is a growing need to apply alternative methods to establish identity,6 as is the case of soft tissue identification, an example being queiloscopy. Cheiloscopy is an area of Forensic Dentistry that applies to the study, registration and classification of lip impressions.7 Greek word of origin, queiloscopy means examination of the lips, where cheilos=lips and skopein=examination.


Objective: Introduction. Global cardiovascular (CV) risk stratification is currently recommended in all adult outpatients in both primary and secondary prevention. Available risk score charts, however, do not include markers of organ damage (OD). Design and method: Aim. To evaluate potential value of adding different markers of hypertension-related subclinical OD to US Framingham, European SCORE and Italian Cuore risk score calculators. Methods. We retrospectically evaluated adult hypertensive outpatients, who underwent blood pressure (BP) assessment and global CV risk stratification at our Hypertension Unit. The following definitions were applied: 1) cardiac OD: electrocardiographic (Sokolow–Lyon index: > 3.5 mV; Cornell Voltage Index: men > 2.4 mV; women > 2.0 mV) or echocardiographic left ventricular (LV) hypertrophy (LV mass index: men > 115 g/m2; women > 95 g/m2); 2) vascular OD: carotid atherosclerotic plaque (>1,5 mm); 3) renal OD: reduced estimated glomerular filtration rate (eGFR < 60 ml/min/1.73m2) or clearance creatinine (ClCr < 60 ml/min). Different risk score calculators were applied to all included patients. Results: Results. We included an overall population sample of 1,979 adult outpatients (44.0% female, age 57.2 ± 13.0 years, BMI 26,6 ± 4,4 kg/m2, clinic systolic/diastolic BP 145.4 ± 18.3/85.8 ± 10.7 mmHg), among whom 117 (5.9%) had cardiac, 161 (8.1%) vascular, and 117 (5.9%) renal OD, respectively. US Framingham, European SCORE and Italian Cuore risk scores were all significantly higher in patients with than in those without OD, independently by type and number of OD, as well as age and gender classes. In particular, direct comparisons for US Framingham CVD death, European ESC score and Italian Cuore score showed significantly higher risk in those patients with both ECG-detected LV hypertrophy, ECHO-detected LV hypertrophy, carotid atherosclerosis and reduced eGFR (Figure 4a) or ClCr than in those without the corresponding markers of OD. Conclusions: Conclusions. Presence of cardiac, vascular or renal OD is associated with higher risk scores, independently by type of calculators, age and gender classes. OD detection should be included in individual CV risk stratification aimed at improving diagnostic and therapeutic process.


Abstract: Uppsala Center for Russian and Eurasian Studies This article examines the online self-staging strategies of famous opera singers of Russian origin in Runet (the Russian-language internet). It argues that, in the Russian media context, opera singers' blogs create an "emotional regime" of high intensity, which helps them to destabilize political hierarchies and intimately connect the grassroots with the political sphere. The study starts from the assumption that the digital environment changes the character of relations between audiences and celebrities in several ways. The most important of these, the paper argues, is that social network communication between opera stars and their fans distorts the traditional limitations and hierarchies.


Mean skin temperature can predict human thermal sensation, but this is difficult to use in field experiment, because it has to measure several body points inside of clothes and many thermistor wires have to be connected from body points to a data logger. Based on this background, the primary objective of this study is to find the local skin points which can predict thermal sensation effectively and to explores how local skin temperature correlates with thermal sensation for the development of portable thermal sensation measurement tool. Temperature of back of the hand and fingertip was selected as point that represents human overall-body thermal sensation and compared with mean skin temperature. The results show that temperatures of back of the hand and fingertip were correlated with human thermal sensation and thermal preference. So, these local skin temperature can be used for prediction of thermal sensation and preference.

Nitrous oxide (N2O) is the third most important greenhouse gas in the atmosphere, and the ocean is an important source of N2O. As the Arctic Ocean is strongly affected by global warming, rapid ice melting can have a significant impact on the N2O pattern in the Arctic environment. To better understand this impact, N2O concentration in ice core and underlying seawater (USW) was measured during the seventh Chinese National Arctic Research Expedition (CHINARE2016). The results showed that the average N2O concentration in first-year ice (FYI) was 4.5 ± 1.0 nmol kg−1, and that in multi-year ice (MYI) was 4.8 ± 1.9 nmol kg−1. Under the influence of exchange among atmosphere-sea ice-seawater systems, brine dynamics and possible N2O generation processes at the bottom of sea ice, the FYI showed higher N2O concentrations at the bottom and surface, while lower N2O concentrations were seen inside sea ice. Due to the melting of sea ice and biogeochemical processes, USW presented as the sink of N2O, and the saturation varied from 47.2% to 102.2%. However, the observed N2O concentrations in USW were higher than that of T-N2OUSW due to the sea–air exchange, diffusion process, possible N2O generation mechanism, and the influence of precipitation, and a more detailed mechanism is needed to understand this process in the Arctic Ocean.

The hydrogen economy envisioned in the future requires safe and efficient means of storing hydrogen fuel for either use onboard vehicles, delivery on mobile transportation systems or high-volume storage in stationary systems. The main emphasis of this work is placed on the high -pressure storing of gaseous hydrogen on-board vehicles. As a result of its very low density, hydrogen gas has to be stored under very high pressure, ranging from 350 to 700 bars for current systems, in order to achieve practical levels of energy density in terms of the amount of energy that can be stored in a tank of a given volume. This paper presents 3D finite element analysis performed for a composite cylindrical tank made of 6061-aluminum liner overwrapped with carbon fibers subjected to a burst internal pressure of 1610 bars. As the service pressure expected in these tanks is 700 bars, a factor of safety of 2.3 is kept the same for all designs. The results indicated that a stress reduction could be achieved by a geometry change only, which could increase the amount of pressure sustained inside the vessel and ultimately increase the amount of hydrogen stored per volume. Such reductions in the stresses will decrease the thickness dimension required to achieve a particular factor of safety in a direct comparison to a cylindrical design.Copyright © 2010 by ASME

To date there has been no agreement with regard to the criteria that define refractory schizophrenia. In this study, we intended to clarify the criteria which psychiatrists use to judge schizophrenic patients as being refractory in Japan. Based on 258 schizophrenic in‐patients (ICD‐10) and their likelihood of discharge, level of psychosocial functioning, mental state and use of medication, the common features of patients who are viewed as non‐dischargeable because of their severe mental state, compared to those of dischargeable patients, were extracted and used as the criteria. The criteria proposed necessitate (i) diagnosis of schizophrenia by standard operational criteria, (ii) continuous hospitalization for at least the past 2 years, (iii) a level of psychosocial functioning of ≤ 40 as measured by the Global Assessment Scale, and (iv) an intensity score of 'marked' or 'severe' on at least three of the six Manchester Scale items (flattened affect, psychomotor retardation, delusions, hallucinations, incoherence of speech and poverty of speech).


The effective mass of phosphorus-doped silicon has been calculated in the light of the Gutzwiller method for highly correlated system. The many-valley nature of the host conduction band minima with a variational impurity concentration dependence is taken into account in the calculation. The results show fair agreement when compared to previous work and available experimental data. Calculation of the density of states at the Fermi energy is also presented for the sake of comparison.

The purpose of the WERC is to train students in the area of site remediation and restoration. Consistent with the Cooperative Agreement`s 3rd Task, the ultimate goal of WERC is to provide training for potential engineers and scientists for the DOE`s remediation and restoration efforts. WERC is sponsored by the Department of Energy and is housed at New Mexico State University. Two student groups from West Virginia University`s Department of Civil and Environmental Engineering traveled to New Mexico. Group 1 was composed of graduate students and Group 2 was composed of undergraduate students. Students who participated in this program were exposed to all aspects of the solution of a real life environmental problem.


The purpose of this study was to investigate the relationships among teacher self-concept, teacher locus of control, and student reading achievement. Twelve male/female sixth-grade teachers from one urban school district in central New York State participated in this imrestigation. The Tennessee Self-Concept Scale and the Nowicki Adult Locus of Control Scale were used to assess teacher self-concept and locus of control. The total reading score from the California Achievement Test was used to measure student achievement. Data obtained from these measuring devices were computer analyzed to determine correlation coefficients among the variables. Statistically significant relationships were not found between teacher self-concept and teacher locus of cori.trol, between teacher self-concept and student reading achievement, and between teacher locus of control and student reading achievement. Based on the results of this investigation, it would be recommended that a replication of this study be conducted with a larger sample to determine if a significant relationship exists among the variables. Further research could be conducted on grade levels other than sixth to determine if a stronger relationship exists among the variables in the yoU11ger grade levels. Further research could also be conducted using different instruments other than the ones used herein.


In the industries like aerospace applications, medical applications and in oil/gas exploration, the electronic components can be exposed to very cold temperatures. In addition, these electronic packages and assemblies may be subjected to vibrations, shocks and impacts. In such harsh surrounding, electronic components may face strain rates of 1 to 100 per seconds and low surrounding temperature up to - 65°C. The records are not available for lead-free solder alloys tested at cold operating temperature and at high strain rates. Earlier published results for SAC305 lead-free solder alloys is restricted to low strain rates and high operating temperatures. For the material SAC305, records are not available for low operating temperatures. In this paper, lead-free solder alloy SAC305 has been tested and studied at several lower surrounding temperature starting from -65°C up to 0°C, with high strain rates. The prepared SAC305 lead-free alloy specimen after reflowing, have been tested at strain rates of 10, 35, 50, and 75 per sec at multiple operating temperatures ranging from -65°C to 0°C. Stress-strain curves are plotted for various low operating temperatures and for the range of strain rates. The calculated experimental data has been fit to the Anand Viscoplasticity model for SAC305 and the Anand constants are established by forecasting the measured stress- strain behavior for the various lower temperatures and high strain rates.


A recent mapping exercise on the level of nurse research in south east London identified four main areas that nurses felt would help get their work off the ground.


"Pseudo-Opinions" in general surveys: How citizens evaluate fictitious politicians. On the basis of a face-to-face and a telephone survey in the general population of an East German city, the city of Dresden, research is done on how citizens evaluate non-existent politicians. Depending on the respective fictious politician between 7% und 15% of the respondents undertake a rating. Noteworthy relations with sex, age and education do not exist, but with political interest: the greater the political interest is, the more often the fictitious politicians are rated. Whether this finding is specific for East Germany or can be generalised deserves further study. 1 Karl-Heinz Reuband ist ordentlicher Professor am Sozialwissenschaftlichen Institut der Heinrich-HeineUniversität Düsseldorf, Lehrstuhl Soziologie II, Universitätsstr. 1, 40225 Düsseldorf, e-mail: email@example.com.

Maintenance represents a significant proportion of the overall operating costs in the mining industry. Despite the large cost of maintenance, management has only given passing attention to the optimization of the maintenance process. The focus has remained on the optimization of mine planning and operations where all the low hanging fruit was picked years ago. Recent initiatives in the field of mobile equipment maintenance have been in the area of remote condition monitoring. In order for an advanced maintenance technology to succeed it must have a strong philosophical basis and the supporting hardware and software infrastructure. A high bandwidth radio network, reliable interfaces, and a real‐time maintenance management system will enable remote condition monitoring systems. Explores reliability centered maintenance, remote condition monitoring, and the use of production and maintenance data for real‐time interactive maintenance management.


This paper reports on studies of the behaviour of a Brownian walker that diffuses in a bidimensional non-homogeneous medium constituted by immobile spherical adsorbing obstacles residing in a continuous solvent. Results show that the probability that the random walker is adsorbed, for a given adsorbing interaction potential between the walker and the surface, depends only on the full adsorbing surface S in the reaction medium, and does not show any appreciable dependence on the size of the adsorbing obstacles. Also, the diffusion coefficient of the random walker depends only on the value of S (for a given adsorbed interaction) if the adsorption energy is large enough. In contrast, when the adsorption energy between the walker and the surface of the adsorbing obstacles is zero, the diffusion coefficient decays exponentially with the volume fraction occupied for the obstacles. The efficiency of the walker to visit all obstacles in the simulation cell depends strongly on the concentration of obstacles and on the adsorbing interaction energy, decreasing quickly to zero with an increase in these parameters.


The theory of rough sets provides a widely used modern tool, and in particular, rough sets induced by quasiorders are in the focus of the current interest, because they are strongly interrelated with the applications of preference relations and intuitionistic logic. In this paper, a structural characterisation of rough sets induced by quasiorders is given. These rough sets form Nelson algebras defined on algebraic lattices. We prove that any Nelson algebra can be represented as a subalgebra of an algebra defined on rough sets induced by a suitable quasiorder. We also show that Monteiro spaces, rough sets induced by quasiorders and Nelson algebras defined on T0-spaces that are Alexandrov topologies can be considered as equivalent structures, because they determine each other up to isomorphism.


Obtaining (on the 1st May, 2004) by Poland and nine other countries, the status of a member of the European Union and the subsequent expansion of the group in 2007 resulted in changes in the Polish trade in services. The purpose of this article is to analyze whether and to what extent there has been intensification of Polish exports and imports to the EU services market? The identification of the effects of our country's accession to the EU in the competitiveness of Polish service providers, measured of the export specialization index. In addition, the author examined the scale of incidence between the Polish and other EU Members of the internal branch exchange. On this basis it was stated, how the differences in technology and equipment in the production factors between the Polish and the EU determined the mutual trade in services. This study uses information of the OECD. The service sector was divided into groups according to the Extended Balance of Payments Services classification (EBOPS 2002).

Metadata is data about data, or information about content. It is important to have standard ways of describing content for efficient resource discovery on the world‐wide web, and to tie this in with information about people and rights to build the foundations for e‐commerce. The most significant emerging standard is the Dublin Core, which has recently stabilized its simple (minimum) set as DC 1.0. Various organizations (including Wiley) have already been exploring the use of Dublin Core tags in a number of implementations. Other initiatives are taking place to bring all metadata schemes within an overarching data model. As the industry responsible for managing content from commissioning through to authenticated release, publishing should play a major role in metadata creation and promulgation.

Science books are one of the most frequently used pedagogical resources in high schools. Their discourse belongs to an expositive type since they posses explicit and clear information about a specific content and in them prevails the basic patterns, such as definition, description, characterization, narration among others. Currently, textbooks are one of the main ways of the teaching of science in our classrooms, and for that reason, it is necessary to examine the most predominant characteristics that are brought to light in them, such as legibility, contents and activities and how these are presented. All these are supposed to influence the quality of the science book as a teaching instrument. In this study three chemistry books corresponding to second year of high school are analyzed in terms of their paragraphs, images and activities and a unit of atomic model of matter is focused on. The selection of these textbooks is due to the fact that one of them is recommended by the Ministry of Education, and the other is used in non public schools and also in public schools. The third is a textbook proposal for college education. The purpose of the study is to identify, given the taxonomy, the relations between contents, the images and the learning activities, considering the cognitive and meta-cognitive variables and how these are presented.


This article focuses on the implementation of the CTEs (Territorial Farm Contracts) in French agriculture. During the left Lionel Jospin's government, this kind of contracts was created by the 1999 Agricultural Orientation Act in order to introduce changes in both the farming policy and individual strategies of farmers. Through the CTEs, farmers and public administration built a new social contract taking into account the implications of farming activities on the environment and countryside in France. Furthermore, the implementation of the CTEs opened the social debate about agriculture to new non-agricultural players (consumers, environmentalists, local authorities, forest owners...). Unfortunately, the CTEs did not receive sufficient social and economic support and could not resist the opposition from the French corporative agrarian lobby (particularly, from FNSEA and CNJA). The centre-right government abolished them in 2003 and created the current CADs (Contracts for Sustainable Agriculture). Paradoxally, the CTEs are today recovering their relevance in the framework of the new EU Regulation on Rural Development, as some European governments consider such contracts are useful to encourage farmers to assimilate the new agricultural and rural policies.

ABSTRACT Eating pathology is generally considered to affect females during adolescence and early adulthood. However, in recent years, there has been an increased recognition that disordered eating occurs in middle-aged and elderly women and that the presentation is similar to that of eating disorders in younger women. In the research presented here, results of an Internet survey of older adult women (N = 245; aged 60–90 years) indicate that the factors significantly associated with eating pathology—perfectionism, depression, and sociocultural pressures to be thin—closely parallel those reported for both younger and middle-aged women.

In this paper we consider the problem of tracking the progression of reading through eye-gaze measurements. Such an algorithm is novel and will ultimately help to develop a method of analyzing eye-gaze data which had been collected during reading activity in order to uncover crucial information regarding the individual's interest level and quality of experience while reading a passage of text or book. Additionally, such an approach will serve as a "visual signature" - a method of verifying if an individual has indeed given adequate attention to critical text-based information. Further, an accurate "reading-progression-tracker" has potential applications in educational institutions, e-readers and parenting solutions. Tracking the progression of reading remains a challenging problem due to the fact that eye-gaze movements are highly noisy and the eye-gaze is easily distracted in a limited space, like an e-book. In a prior work, we proposed an approach to analyzing eye-gaze fixation points collected while reading a page of text in order to classify each measurement to a line of text; this approach did not consider tracking the progression of reading along the line of text. In this paper, we extend the capabilities of the previous algorithm in order to accurately track the progression of reading along each line. the proposed approach employs least squares batch estimation in order to estimate three states of the horizontal saccade: position, velocity and acceleration. First, the proposed approach is objectively evaluated on a simulated eye-gaze dataset. Then, the proposed algorithm is demonstrated on real data collected by a Gazepoint eye-tracker while the subject is reading several pages from an electronic book.


Rest Functional Magnetic Resonance Imaging (rfMRI) Dynamic Functional Connectivity (DFC) Autism Spectrum Disorder (ASD) Typical Control (TC) Autism spectrum disorder (ASD) is a highly prevalent neurodevelopmental disorder characterized by impaired social communication and restricted and repetitive behaviors. Comparison study between ASD and typically control (TC) subjects through magnetic resonance imaging (MRI) provides valuable understanding for differences in brain function. Recently, through dynamic functional connectivity (DFC) analysis, it is found that brain functional connectivity possesses dynamic nature and shows transient connectivity patterns ("states") repeating over time. In this comparison study between ASD and TC, we employed the rest functional MRI (rfMRI) data of San Diego State University (SDSU) of ABIDE II database to examine the brain intra and inter network connectivity and also to investigate the relations of age and social responsiveness scale (SRS) score (score measuring autistic traits) to brain inter regions connectivity strength. These aims were implemented in all DFC states. The ASD subjects experienced more the state with less intra and inter network connections. Further, the DMN segregation reduction from other functional networks emerged as a common them. Furthermore, in ASD, the connection strength between auditory and visual networks was decreased by increasing the age. In ASD, the SRS had more positive relation to connectivity strength existing between cerebellar, auditory, visual networks and cognitive control network in comparison to TC. All these results demonstrate that some differences exist in brain network connection of ASD in comparison to the TC subjects and these differences can be more distinctively revealed by employing DFC analysis.

The eccentric load behaviour of circular reinforced concrete columns strengthened with a novel engineered cementitious composite jackets reinforced with synthetic macro-fibres and polypropylene was investigated. Furthermore, an innovative method of interface treatment known as longitudinal grooving was used. Twelve test columns were cast, six of which were strengthened with 15 mm thick composite jackets while three were strengthened with ultra-high-performance-fibre-reinforced concrete jackets. Moreover, three of the six columns strengthened with the composite jackets were additionally confined with glass-fibre-reinforced polymer warps. The experimental results showed that both methods enhanced load-carrying capacity and energy dissipation with increasing load eccentricity. For example, the specimens strengthened with the composite jackets exhibited increases of 167% and 194% in load-carrying capacity, and enhancements of 92% and 53% at eccentricities of 30 and 60 mm respectively. Finally, the previously reported model and different codes were used to validate the results, from which interaction diagrams were drawn. This showed a good agreement between experimental and predicted results.


The production cost of chili in the fertigation system has increased recently due to the high cost of water-soluble fertilizers used in the system. Laundry greywater and biodegradable vegetable waste are rich in nutrients essential for plant growth. Thus, this research aims to investigate the effects of greywater organomineral fertilizer (OMF) on the chili plants' growth and yield performance in the fertigation system. The experiment was laid out in a completely randomized design under the rain shelter. OMF produced from laundry water and vegetable waste was applied with chemical fertilizer (CF) in different ratios, including 100% CF (T1, control), 75% CF + 25% OMF (T2), 50% CF + 50% OMF (T3), 25% CF + 75% OMF (T4), and 100% OMF (T5). Results showed that the combined use of CF and OMF produced non-significantly different chili plants from those solely treated by CF. Interestingly, chili plants treated with 50% CF and 50% OMF increased the yield by 4.71% compared to CF. Chili plants treated with 25% and 50% OMF showed non-significantly different plant height, stem diameter, plant dry weight, fruit number, and proximate composition of fruits over those treated with 100% CF. Solely application of OMF produced similar chili as CF in terms of fruit quality. The present study shows that plant performance and yield of chili were improved after the application of CF and OMF at a ratio of 50:50. It can be concluded that OMF has the potential to be used as an alternative for replacing 50% of chemical fertilizer in chili fertigation system without affecting its growth and yield.

Modern management of transport systems is characterized by the use of innovative automated and information systems. At the same time, digital technologies are being used to bring the transport system management model to a qualitatively new level. The use of such systems improves the development of vehicle management.


The invention relates to a method for controlling content of hydrogen in a zinc dissolving tank for electro-galvanizing, which comprises the following steps: arranging a hydrogen concentration detection instrument on a fog discharge pipeline connected to the zinc dissolving tank so as to monitor the hydrogen concentration in the zinc dissolving tank in real time; arranging a supporting plate with an inclined part in the zinc dissolving tank so as to be used for bearing zinc particles, and at least forming a plurality of through holes in the inclined part; when the hydrogen concentration reaches a first threshold, reducing the rotating speed of a zinc dissolving pump to the minimum, and starting a standby fan of a fog discharge system; and when the hydrogen concentration reaches a second threshold, enabling the zinc dissolving pump to stop working, and discharging the electroplating solution in the zinc dissolving tank to enable the liquid level in the zinc dissolving tank to be at least reduced to the position below the supporting plate, wherein the second threshold is greater than the first threshold. In addition, the invention also provides a zinc dissolving system which can implement the method. By adopting the control method and zinc dissolving system provided by the invention, the hydrogen concentration in the zinc dissolving tank is controllable, and the production safety and stability are effectively increased.


Of all the building types that emerged in the twentieth century, none confounds more than the parking garage. The garage has long intrigued architects, and designers from Wright to Koolhaas have deliriously dabbled with its confoundedness. A book has finally emerged that explains this phenomenon and emphatically gives the garage its rightful place in the architectural canon. Simon Henley's The Architecture of Parking examines the physical, spatial, and emotive potential of these mute megaliths and has selected an excellent array of case studies to make his case. His book includes color photos accentuated by grainy, brooding full pages of grayscale, and consistently scaled line drawings. The clarity of Henley's writing and purpose—with a few exceptions—makes this book a long-awaited success. Henley enthusiastically chronicles the development of the garage through the century, polemicizing that structures housing cars deeply influence the design of buildings for people, not the other way around. The overall quality of this book makes this argument tantalizingly believable. The first decade of the twenty-first century seems to be celebrating the garage's centennial. Henley's book and Shannon McDonald's Parking Garage: Design and Evolution of a Modern Urban Form (2007) parallel other recent texts in planning and urban history, and the work of both authors was included in a show on parking at the National Building Museum in early 2010. Henley's book showcases structures that rise to the level of high architecture. Most garages he discusses are by known architects, but those included as ''accidents of utilitarianism'' seem to excite him the most. He regards many as beautiful. Henley organizes his case studies into four sections around abstract notions of matter, elevation, light and obliquity, all prefaced by an introduction and a discussion of aesthetics. The chapter entitled ''matter'' focuses primarily on concrete at its most visceral and haptic (a favorite word of Henley's). In the manner of Robert Smithson, Henley appreciates concrete's entropic weathering. Paul Rudolph's Temple Street Garage stands out particularly, photographed as if its spiral ramp was part of a ribbon of highway, coiled in shadows like a python. Henley's use of the term ''elevation'' in the chapter of the same name embraces a garage's rhetorical potential. He moves beyond the literalness of early ''classic'' garages to elevations focused on pattern, rhythm, scale, and semiotics. Michael Blampied's diagrid garage in London is this chapter's real find. The following chapter on ''light'' (or lack of) is about emotive potential. Here, Henley dwells on sensation, both ecstasy and dread. He uses the sublime true to Edmund Burke's original meaning, describing garages as strange and grotesque places that are simultaneously open to ''spiritual interpretation.'' He uses the Pantheon-like ocular effect created by spiral ramps to make his point. Notable here is the Parc des Celestins garage in Lyon, a dramatic and macabre encounter worthy of Piranesi's Carceri. The final chapter, ''obliquity,'' is about the mash up of ramps and vertical infrastructure as a form of symphonic resolution: here, Henley's themes come together with the parking structure as a fully integrated organ in the body of the city. The crescendo is Bertrand Goldberg's Marina City, which Henley crowns ''the most heroic parking structure ever built.'' Henley outlines a three-phase history of the parking garage in the introduction: a protean phase where prophetic notions emerge from earlier forms like the stable; a minimalist, post-war classic phase that leads to the present moment: a baroque phase characterized by either technique or a striving ''delirious in its search to create new forms.'' This timeline frames Henley's polemical first chapter, which argues that the garage influenced modern architecture and was not simply a parallel development. A more traditional history would situate the garage's development as part of modernism and its response to cultural and technological change, citing Robert Law Weed's 1948 minimalist garage in Miami and Mies' Farnsworth house as similar but uncoordinated expressions of historical imperative. Kenneth Frampton offered an opening salvo when he described Wright's Gordon Strong Pavilion (a protogarage) as the progenitor to the Guggenheim Museum. Henley takes Frampton's lead, connecting Melnikov's Car Park for a 1,000 vehicles to OMA's

other than their illness; for this reason other criteria have been taken to assess their progress. The benefit of protein in this disease has largely been based upon the effects of diet in nutritional liver disorders. In the present series it is of interest to note that those on the experimental diet did not show any improvement over those in the control series. This is in striking contrast to the claims made by Beattie (1943-4), who has stated that with hepatitis it was possible to reduce the time spent in hospital by as much as 37% by dietetic measures alone. He further states that, roughly, the average stay in hospital is inversely proportional to the daily intake of protein. It is not clear to which type of hepatitis he refers, nor how much protein is given, but he quotes an average of 150 g. of protein a day in one series-the figure used here. The active principle in preventing nutritional liver disorders has been traced to sulphur-containing amino-acids, of which methionine appears to be the foremost. It is not possible to determine the methiorrine content of the diets used in our series, but it is interesting to observe that Wilson et al. (1945) and Higgins et al. (1945), using oral methionine, were unable to find any statistical difference, using comparable criteria to assess progress. Macrae et al. (1943) have demonstrated that the protein intake of the R.A.F. has exceeded the generally accepted standards of protein requirements. Whether the. self-limitation of the disease as shown in Table I is due to the probable protein stores can only be a matter of conjecture. Himsworth and Glynn (1945) have pointed out that the case-mortality rate of the disease of allied, pathology-post-inoculation jaundice -was 2.5% in the cases of Fox et al. (1942), whereas that in the cases of Findlay et al. (1944) it was 1.5%, the difference being considered to be due to the relatively poor nutrition of Fox's cases. This may suggest that the effect of protein is maximal as a protective but not as a restorative measure, and that, as protein deficiency is not found in the R.A.F., this may be the reason for the similarity of the two series. It is clear, however, that no harm arises as the result of the increased protein, and, in the meantime, a further experiment on similar lines is being undertaken with widely divergent protein intakes.


Trypanosomatids are eukaryotic parasites that migrate between insect vectors and mammalian hosts. They cause a number of serious diseases with major impacts on human health on a global scale. One example is Leishmania, which causes Leishmaniasis, a disease that affects approximately 12 million people in Asia, Middle East, Africa, South America and Southern Europe. Trans-splicing of trypanosomatid polycistronic transcripts produces polyadenylated monocistronic mRNAs that are modified at their 5'ends to form the cap4 structure (m7Gpppm36,6,2'Apm2'Apm2'Cpm23,2'U). Two trypanosomatid translation initiation factor 4E isomers (eIF4E3 and eIF4E4) have extended N-terminal regions that include PAM2 motifs; these regions can interact with PABC domains in the poly(A)-binding proteins PABP1. Using NMR, X-ray crystallography and biophysical quantitation of biomolecular interactions, we show that tight binding between Leishmania eIF4E4 and PABP1, mediated largely by hydrophobic interactions, underpins a novel architecture in the translation factor complex bridging the 5' and 3' ends of the monocistronic mRNAs. We demonstrate that this complex can also accommodate Leishmania eIF4G3 which, in contrast to the standard eukaryotic initiation complex paradigm, is found to bind to eIF4E4, but not to PABP1. Exceptionally, therefore, by binding to two protein ligands and to the mRNA cap4 structure, the trypanosomatid N-terminally extended form of eIF4E acts as a core molecular scaffold for the mRNA-cap-binding complex. Finally, our data indicate that the eIF4E4 N-terminal extension is an intrinsically disordered region that transitions to a partly folded form upon binding to PABP1.


The analysis of Silberstein's study 'to ascertain whether television viewing, regardless of content, alters the frequency composition of the ongoing EEG leading to an increase in delta, theta and alpha activity, and a decrease in beta activity', is discussed. Silberstein's results were found to confirm the hypothesis.


This study used microbial indicators to assess the hygiene status of 383 migrant food handlers from 3 urban cities in Peninsular Malaysia. Microbiological analysis revealed that all the hand swabs tested 99.5% positive for aerobic plate counts (mean [M] ± standard deviation [SD] = 3.57 ± 0.83 log10CFU [colony forming unit]), 20.8% positive for total coliform/Escherichia coli (M ± SD = 0.30 ± 0.67 log10CFU), and 63.4% positive for Staphylococcus aureus (M ± SD = 1.38 ± 1.26 log10CFU). In addition, aerobic plate counts and Staphylococcus aureus counts exceeded the acceptable standard levels. Bacterial counts were found to be significantly associated with subjects' country of origin (P = .019) and working responsibilities (P = .001). Our findings indicate high probability of transmission of pathogenic bacteria from the food handlers' hands to customers during meal preparation and serving. This calls for improvements in personal hygiene and sanitation standards by the relevant health authorities among migrant food handlers.


Purpose: to investigate the state of the clinical component of the continuum of psychological adaptationmaladaptation in patients with a dermatological profile with diseases of various levels of vital threat, in order to develop, in the future, personalized psychocorrection programs for this category of patients. Contingent and research methods. On the basis of informed consent, in compliance with the principles of biomedical ethics and deontology, we examined 120 dermatological patients who were treated in three branches of the clinic "Dr. Zapolska Clinic" during 2020-2021, namely: 60 patients with non-vital dermatological diseases (seborrheic keratosis L82, condylomas A63.0, angiomas D18.0, pigmentation disorders L80), and 60 patients with dermatological diseases posing a vital threat ( melanoma C43, basal cell carcinoma C44, skin carcinoma D04). The results. Among patients with dermatological diseases, there are both psychologically adapted and maladapted individuals, regardless of the vitality/non-vitality of the pathological process. Among persons with signs of psychological maladjustment with non-vital dermatological diseases, the majority are persons with individual signs of maladjustment or with manifestations of neuroticism with a high level of psycho-emotional tension, while in the sample of patients with vital diseases and the presence of maladaptive manifestations, persons with high neuroticism and psycho-emotional tension predominate , as well as patients with pronounced pathopsychological symptoms of syndromic and/or nosological delineation. In patients with a dermatological profile with signs of psychological maladjustment, the clinical picture is dominated by anxious (mainly in patients with non-vital diseases) and depressive (mainly in patients with vital diseases) radicals, and auxiliary psychopathological constructs are represented by manifestations of somatization, obsessive-compulsive symptoms, interpersonal sensitivity and phobic anxiety. Affective symptomatology is most pronounced in patients with maladjustment with vital dermatological diseases, it is less pronounced in patients with non-vital skin pathology, and the severity of individual indicators of anxiety-depressive response in the examined subjects without signs of maladaptation does not differ significantly in the examined depending on the nature of the dermatological pathology (non-vital or vital). The presence and intensity of maladaptive pathopsychological-affective reactions of varying degrees of severity in patients with dermatological pathology are not clearly associated with the vitality of the dermatological process, but are based on more complex mechanisms of the mutual influence of biological predisposition and psychological and psychosocial factors, the mosaic combination of which determines the individual's resource capabilities for constructive acceptance the fact of the presence of a dermatological disease and the development of an adequate strategy for its mastery, regardless of the severity of the disease. Conclusion. The identified regularities should be taken into account when developing treatment-rehabilitation and psycho-prophylactic measures in patients with dermatological pathology with different levels of vital threat.


The ice was never supposed to melt this quickly. Although climate scientists have known for some time that global warming was shrinking the percentage of the Arctic Ocean that was frozen over, few predicted so fast a thaw. In 2007, the Intergovernmental Panel on Climate Change estimated that Arctic summers would become ice free beginning in 2070. Yet more recent satellite observations have moved that date to somewhere around 2035, and even more sophisticated simulations in 2012 moved the date up to 2020. Sure enough, by the end of last summer, the portion of the Arctic Ocean covered by ice had been reduced to its smallest size since record keeping began in 1979, shrinking by 350,000 square miles (an area equal to the size of Venezuela) since the previous summer. All told, in just the past three decades, Arctic sea ice has lost half its area and three quarters of its volume.


The problem of simultaneous attack of multiple missiles against a maneuvering target is considered in this paper. In order to improve the operational effectiveness and reduce the communication burden, it is supposed that the missile can communicate with its neighbors. Consider the unknown maneuverability of the target, the cooperative is composed of two components, one is used for time coordination and the other is used for target capture. The uncertain maneuverability of the target is estimated by the aid of extended state observer and compensated in the distributed algorithms. In the end, a numerical example is given to illustrated the effectiveness and superiorities of the proposed method.

Scientists apply Bacon's investigative induction by first cataloguing experimental discrepancies among apparent natures of things. Induction begins by multiplying discrepancies, thus creating a puzzle with multiple clues. Solved puzzles thus give us power to produce those unusual, discrepant effects. Bacon's experimental method, however, is not empiricist. Grasping things empirically, like receiving impressions on a wax tablet, presupposes that our senses cannot deceive us whenever we are deceived: we err in our interpretations. Empiricism thus leaves no objective discrepancies to resolve, as deception resides in our interpretation. Scientific induction, for all its success, becomes invisible to modern empiricist methodologists


Abstract We examine the extent to which offer prices reflect public information for 3,325 IPOs over the period 1990–1999. We focus primarily on four variables: share overhang, file range amendments, venture capital backing, and previous issue underpricing. We show that 35%–50% of the variation in IPO underpricing can be predicted using public information known before the offer date and therefore conclude that IPO offer prices underadjust to widely available public information to a much greater extent than previously documented.


A Bandwidth reconfigurable microstrip antenna has been presented in this paper. Dual layer circular patch antenna structure has been used. Geometrical variation in horse shoe structure used as lower patch is responsible for controlled bandwidth variation. The proposed antenna structure provides bandwidth variation from 90.99 MHz to 144 MHz at constant resonant frequency of 3.4GHz.


The capacity of the farmers in distributing their income properly is their biggest challenge. Helping them in income management, livelihood, facilitating, and conducting programs that will help them be trained in crop management are the purposes of this study. This study aims to test the difference between the profile of the respondents to their financial literacy and income distribution. More so, it tests the significant relationship between their financial literacy and income distribution. The descriptive quantitative method that used the purposive sampling technique was participated by the farmers harvesting Palay in San Pablo City using standardized questionnaires. Findings revealed that gender, educational attainment, and monthly income differ significantly with financial literacy as to behavior. Financial literacy based on attitude and behavior; family needs have an inverse correlation. However, when it comes to debt repayment, a positive correlation represents the attitude and behaviors of the farmers towards paying their debts. Most male Palay farmers earn below PHP10,000; they spend less than they make and seldom save money. As most farmers were older males, they have a high level of income distribution on their basic family needs having a high level of literacy on financial matters in terms of attitude. Farmers who are low-income earners prioritize family needs, and they have a positive attitude and behavior toward paying their debts. Therefore, there is a positive correlation between financial literacy regarding mentality and behavior and income distribution regarding family needs and debt repayment.

The transformations in the world of contemporary labor, marked by the process of productive restructuring of capital and incorporated into the neoliberal logic, have promoted a significant increase in levels of precariousness of work, and consequently triggered severe changes in the role of the State, in the configurations of social and in the labor market of the social worker. Being Social Service a profession inserted in the social and technical division of labor that works in the public and private spheres, formulating and implementing proposals to face the multiple expressions of the social question that plagues the working class, suffers the repercussions of the precariousness of the relations and conditions of work and the new configurations of social policies unleashed in the neoliberal scenario by the deregulation of the State that becomes minimal for the social. In this sense, the present work seeks to identify the roots of transformations in the world of work in the capitalist system that affect the intensity of the energy expenditure -physical and / or psychic -to carry out the work, to understand the repercussions of such transformations in the labor market based on the precarious conditions of work and the dismantling of social policies and analyze their implications in the professional practice of Social Work


As known, Colebatch and Rosengren from Australia successfully demonstrated ocular vestibular-evoked myogenic potential (oVEMP) in 2005. With the introduction of oVEMP and previously developed cVEMP, clinical neuro-otologists thus could assess otolithic organ function via subjective tools. Because of its importance, research on the VEMP test has dominated neuro-otological studies for the recent two decades. Meanwhile, applying VEMP tests in vestibular clinic is also more and more important for assessing otolithic organ function. In general, oVEMP test predominantly assesses the utricular function via crossed vestibulo-ocular reflex (VOR) pathway. Physiologically, the utricle detects head acceleration in horizontal vector, stabilizing head position and aiding postural balance. More precisely, utricular macula senses a shearing force related with the otolith displacement in response to head motion. Hence, hair cell then deflects and triggers actional potential, which transmits via efferent fibers (mainly the superior vestibular nerve) to the central nervous system for further equilibrium sensation coordination. With the feature of sensing acceleration change, there are two stimulation modes to stimulating utricle and eliciting oVEMP responses clinically, including air-conducted sound (ACS) and bone-conducted vibration (BCV). The ACS stimulation utilizes 500 Hz click sound with the intensity of 105dBnHL. For the BCV stimuli, it was generated by a vibrator placed on the subject's head, inducing a maximal acceleration of 0.3g along the y axis, about 128dB force level. However, BCV-oVEMP is more preferred in clinical setting than ACS mode because the latter yields small response and unreliable results.
Though BCV mode serves the proper way to elicit oVEMP response, the optimal stimulation site remains unclear. According to previous studies, it is known that oVEMP could be elicited by skull tapping along the mid-sagittal plane at Fpz, Fz, Cz, and inion sites, within which, the forehead tapping results in most optimal response in terms of reflex amplitude (Lin et al., 2010). And subsequent healthy control study further demonstrated that tapping at Fpz (10% of the nasion-inion distance from nasion) and Fz (30% of the nasion-inion distance from nasion) sites both result reliable oVEMP results (Lin et al., 2012). Nevertheless, Fpz and Fz still yield inconsistent oVEMP results, probably attributed to inter-individual difference along the energy transmitting from forehead to the otolithic organ. For example, frontal sinus development, skull density, intra-cranial soft tissue distribution, even the frontal disease (e.g., frontal sinusitis) all alter acceleration profiles to some extent. Based on above, to investigate possible interfering factors in energy transmission within oVEMP elicitation is necessary to improve oVEMP test protocol.
In this dissertation, we performed a series of experiments to examine the effect of frontal sinus on head vibration. In clinical part, patients of various ages and genders together with various extents of frontal sinus development were recruited to examine possible factors affecting oVEMP responses in pathologic ears. While in laboratory part, acceleration profile change in systems with various air volume and filling materials via different dummy models was investigated. Current results revealed that the presence of frontal sinus would affect the oVEMP responses, likely via altering skull vibration profile after forehead vibration stimuli. Besides, inadequate pneumatization and pathological status of frontal sinus both lower oVEMP response rates. Our next step will focus on examining whether removing frontal sinus disease would strengthen oVEMP response and whether oVEMP response could reflect frontal sinus condition.


Global genomic disparities appear inevitable in the age of genomic scientific breakthrough. The highly industrialised nations of the world currently are at major advantage of implementing programmes to establish personalised medical services to affluent class in the technological advanced nations. This project explored the characteristic diseases of poverty which exist in epidemic proportion in the underdeveloped areas of the world. The major factors which facilitate genomic disparities were outlined as the tripartite linkage of diseases, poverty and the very high illiteracy level. The need to harness the benefits of biomedical informatics, as a 'technology of hope' in food production, health maintenance and wealth creation was emphasised. The various landmarks achieved in genomics science were outlined. Although these scientific developments have created the foundation for personalised medical services, researchers, national medical administrators have cautioned clinicians and physicians to pay serious attention to the issues of epidemiological evaluation of their gene testing services so as to maximise health benefits and minimise harm to unsuspecting healthcare consumers. A logic model illustrating strategies to eliminate global genomic disparities in personalised medical services was presented.


A 37-year-old woman presented with vague upper abdominal pain and dyspepsia. Clinical examination was unremarkable. Gastroscopy showed a smooth 'bulge' at the junction of the gastric body and fundus along the greater curvature with normal overlying mucosa. Biopsy revealed inflammatory changes but no dysplasia or malignancy. CT scan showed well-defined gastric body wall mass (figure 1). She underwent a wedge resection of the mass with normal gastric margin without regional lymphadenectomy.

This article describes the additional customer attractions introduced by a city centre underground car park in Helsinki, Finland. Some services promote car maintenance; others aim more to catch customers' interest, such as displays of vintage cars, children's rides and recorded birdsong accompanying information boards. Also displayed are the results of a car hitting a moose, to encourage drivers to use winter tyres and be alert on the road. Customised payment cards and cell phone coverage are offered among other customer incentives. The measures help to attract drivers to the city centre car parks rather than out-of-town shopping centres.


Marine strata of the Upper Silurian - Lower Devonian Sierra Grande Formation in northeastern Patagonia (Argentina) comprise silty to very coarse quartzites, siltstones, quartzglomerates and ferrilites.Based on sediment - body geometries, mechanical and biogenical structures and textures, eight sedimentary facies were recognized and grouped into five facies associations.The studied deposits were formed in a shallow open marine shelf dominated by wave and storm processes. Most (sandstone and conglomerate) facies were deposited between the beach and the upper - shore -face. The offshore deposits are represented by heterolithic facies formed under alternating fair weather and storm conditions. Paleocurrent measurements of directional structures (wave-ripples and cross beds) suggest that the local position of the shoreline was northeast-southwest. They also show that subtidal shad bars were mainly induced by longshore currents.Iron concentration was favoured by open and shallow marine environments, very slow sedimentation rate, warm paleoclimatic conditions in the source areas and a general sea level rise during the deposition of the Sierra Grande Formation.


The authors present a new parametrization for the embedded-diatomics-in-molecules (EDIM) potential energy function that is significantly more accurate than the previous one for the interaction of two H atoms with a Ni surface or with a third H atom. Thus, it can be used to study lateral interactions of H{sub 2} with H, and it is also parametrized for a system of three H atoms on a Ni surface. In addition, the metal atom parameters are independent of which layer the metal atom is in so there is no ambiguity in studying reactions at steps or kinks. They apply canonical variational transition state theory with semiclassical transmission coefficients to investigate the dynamics of the dissociative chemisorption of gas-phase H{sub 2} molecules on both single-crystal-face and stepped Ni(100) surfaces. They also consider the effect of additional H atoms, and they compare results for clean and partially covered surfaces. They find that classical transition-state recrossing and quantal tunneling effects are very important in the dissociation of H{sub 2} on the clean Ni(100) surface.


A 58-yr-old man presented with multiple hepatic lesions found during a diagnostic evaluation for unintentional weight loss. Needle biopsy indicated a well-differentiated neuroendocrine tumor with a low proliferation index ( 2%). The patient denied flush or diarrhea, and the clinical investigation revealed no signs of heart failure. Biochemically increased levels of chromogranin A (1335.6 g/liter; reference, 19.4–98.1) and urinary 5-hydroxy indoleacetic acid (156 mol/liter/24 h; reference, 47) were found. Somatostatin receptor scintigraphy revealed a strong enhancement of the known liver lesions but no further uptake in the gastrointestinal or pulmonary area. However, a strongly positive lesion emerged in projection of the left atrium (Fig. 1A). Echocardiographically, this lesion translated into a solid tumor of 3 cm within the left atrium (Fig. 1B). Ventricular function was normal, without evidence of carcinoid heart disease. Surgical extraction was performed (Fig. 1C), and histologically the cardiac tumor consisted of neuroendocrine tissue with an identical immunohistochemical profile to the hepatic lesions and a similarly low proliferation index. Neuroendocrine tumors can arise in various locations (1), and the cardiac sequelae of increased levels of serotonin are well known (2). Although several reports have described tumors located within the myoand pericardium (3, 4), a tumor arising within the left atrium has not been reported so far. Based on the present findings and despite extensive immunohistochemical evaluation, it cannot be determined whether the cardiac lesion represents the primary tumor or a metastasis. Interestingly, the patient reported removal of a pulmonary tumor more than 40 yr ago in Turkey, indicating the possibility of a primary neuroendocrine tumor in the pulmonary system. Unfortunately, the corresponding medical documents could no longer be located.


Background and Aims: The purpose of this study was to evaluate the mechanical properties of flowable dental composites containing the antibacterial compound. Materials and Methods: The study was conducted through experimental design. Compound 3(2,5Dimethylfuran-3-yl) -1H-pyrazol-5(4H)-one were synthesized using Ethyl chloroformate, hydrazine hydrate and 3-acetyl-2,5-dimethylfuran. In this study we had six experimental groups consisting of five resin composites containing 3(2,5dimethylfuran -3-yl) -1H-pyrazole-5 (4H) -one in different concentrations of 1, 2, 3, 4, and 5 wt.% and one control group with no additive. They were prepared by high speed mixer at room temperature and under normal conditions for humidity and temperature, using standard 4049 compressive strength tests. Their diametral tensile and flextural strength were evaluated. Results: With increasing percentage of antibacterial compound The flexural strength decreased but this difference was not significant between the 1% and control groups.(p>0.05) The results of diametral tensile strength showed that there was no significant difference between the control group and 1% but the compressive strength significantly decrease by increasing the percentage of compound 3(2,5dimethylfuran -3-yl) -1H-pyrazole-5 (4H) -one.(p<0.05) Conclusion: The combination of antibacterial component, although leads to an acceptable increase in the antibacterial properties of flowable dental composites and in Their flextural and tensile strengths had no effect, but a significant decrease in their compressive strengths, which could limit their use.
