Design of substrate integrated Waveguide single longitudinal slot antenna

Planar slot antenna using Substrate Integrated Waveguide technology (SIW) is proposed in this paper. SIW has all the advantages required for a small size antenna package: Lowcost, high-performance and ease of integration. The SIW antenna with tapered microstrip-SIW transitions are integrated and synthesized on a single substrate. This structure is designed with Finite Element Method (FEM) using HFSS on substrate of Duroid 5880. Simulated results are presented and discussed.
The East in the West

Sociological and historical enquiry in Europe has had as a continuing pre-occupation the problem of the Uniqueness of the West, the search for factors that can be held responsible for its achievements in the modern world and in particular the emergence of industrial capitalism. That search has led to a devaluation of the East and consequently a mistaken self-understanding of the West. This article attempts to outline the problem with regard to rationality, commercial literacy (book-keeping), mercantile enterprise and family participation in such activity. Sociologues et historiens, préoccupes par de l'Occident, ont cherché avec constance les facteurs responsables de l'avènement du monde moderne et du capitalisme industriel. Ce faisant, ils ont développé une sousestimation des civilisations de l'Orient et par voie de conséquence une lecture fausse de l'Occident. Le travail dont cet article donne la primeur s'attaque à ce problème en considérant la rationalité, la diffusion de l'écrit, l'entreprise commerciale et la participation familiale à ces activités. Seit langem setzen sich in Europa soziologische und historische Studien mit der Einmaligkeit des Abendlandes auseinander. Sie erörtern jene Elemcnte, die fur das Entstehen der »modernen Welt«, insbesondere des Kapitalismus entscheidend sind. Die Forschung hat dabei die Bedeutung des Orients vernachlässigt und folglich die Entwicklung der westichen Welt falsch eingeschätzt. Goody untersucht diese Problematic, indem er auch die Rationalität, das Buchwesen, die Handelshäuser und die familiäre Beteiligung an diesen Unternehmcn in scine Betrachtung einbezieht.
Plasma enhanced atomic layer deposition of zinc sulfide thin films

Zinc sulfide thin films were deposited by plasma enhanced atomic layer deposition (PE-ALD) using diethylzinc and H2S/Ar plasma. The growth characteristics were studied in situ with spectroscopic ellipsometry and ex situ with x-ray reflectometry. The growth was linear and self-limited. Furthermore, it was demonstrated that the growth per cycle was less temperature dependent for the PE-ALD process compared to the thermal process. ZnS thin film properties were investigated ex situ using x-ray photoelectron spectroscopy, x-ray diffraction, ultraviolet/visible optical spectroscopy, and atomic force microscopy. The as-deposited films were crystalline with a transmittance of >90% and a band gap of 3.49 eV. ZnS films deposited by PE-ALD were smoother than films deposited by thermal ALD. The plasma enhanced ALD process may have an advantage for ALD of ternary compounds where different temperature windows have to be matched or for applications where a smooth interface is required.
Forecasting the Effects of In-Store Marketing on Conversion Rates for Online Shops

As webstores usually face the issue of low conversion rates, finding ways to effectively increase them is of special interest to researchers and practitioners alike. However, to the best of our knowledge, no one has yet empirically investigated the usefulness of various in-webstore marketing tools like coupons or different types of product recommendations. By analysing clickstream data for a shoe and a bed online store, we are contributing to closing this gap. In particular, we use our present data to build more general hypotheses on how such purchasing incentives might function and on how they could be used in practice.
Undergraduate students’ perceptions of and responses to exemplar-based dialogic feedback

Abstract This study aims to explore undergraduates’ perceptions of and responses to exemplar-based dialogic feedback. Forty-eight undergraduate teacher education students of Chinese language, science and social science participated. Semi-structured interviews, classroom observations and reflective journals were used to collect data. Students reported both benefits and challenges of exemplar-based discussion, which depends largely on the quality of the dialogic feedback. Three patterns of response were identified in the discussion: no response, moderate response and active response. Three factors influenced their responses: personal qualities, the availability of a supportive environment and teacher scaffolding. Reconceptualisation of feedback and pedagogical implications are discussed.
Improvement Frequency of Information Access and Anxious, Impact on The High Level of Compliance Protocol Prevention COVID-19 in Nurse Candidates

The spread of the COVID-19 virus which has become a pandemic is thought to cause changes in health behavior in nurse candidates. The purpose of this study is to identify changes in health behavior of nursing students in the form of seeking health information and increasing anxious about the possibility of contracting the virus, which is thought to have an impact on increasing compliance with health behavior. This type of research is an online survey with cross-sectional design. Data collected from nursing students in their late teens were statistically analyzed by the correlation test. The results showed that increasing literacy in seeking information about COVID-19 cases from social media and a fairly high increase in anxious had an impact on increasing compliance with preventing the spread of the virus. However, it was found that exposure to case information did not increase anxious in respondents. The conclusion of this study is the need for increased health literacy to create compliance with the COVID-19 virus prevention protocol at the same time as an increase in anxious.
Football and the authoritarian regime in Iran

ABSTRACT The history of football in Iran is made up of contradictory processes, as the weight of successive authoritarian regimes is counterbalanced by international regulations and by players’ and spectators’ attitudes. The state is trying to control the world of football and use it for its diplomatic relations. The article analyses the regime’s fears and reactions to several phenomena that pose danger to it: supporters’ outbursts that run counter to religious morality, political protests in stadiums, and women’s demands.
State of the world's freshwater ecosystems: physical, chemical, and biological changes.

Surface freshwaters—lakes, reservoirs, and rivers—are among the most extensively altered ecosystems on Earth. Transformations include changes in the morphology of rivers and lakes, hydrology, biogeochemistry of nutrients and toxic substances, ecosystem metabolism and the storage of carbon (C), loss of native species, expansion of invasive species, and disease emergence. Drivers are climate change, hydrologic flow modification, land-use change, chemical inputs, aquatic invasive species, and harvest. Drivers and responses interact, and their relationships must be disentangled to understand the causes and consequences of change as well as the correctives for adverse change in any given watershed. Beyond its importance in terms of drinking water, freshwater supports human well-being in many ways related to food and fiber production, hydration of other ecosystems used by humans, dilution and degradation of pollutants, and cultural values. A natural capital framework can be used to assess freshwater ecosystem s.
Discovering Influencers for Spreading in Weighted Networks

Identifying the influential nodes in networks is an important issue for efficient information diffusion, controlling rumors and diseases and optimal use of network structure. The degree centrality which considers local topology features, does not produce very reliable results. Despite better results of global centrality such as betweenness centrality and closeness centrality, they have high computational complexity. So, we propose semi-local centrality measure to identify influential nodes in weighted networks by considering node degree, edges weight and neighboring nodes. This method runs in O(n(k)2). So, it is feasible for large scale network. The results of applying the proposed method on weighted networks and comparing it with susceptible-infected-recovered model, show that it performs good and the influential nodes are generated by our method can spread information well.
Paracentral Acute Middle Maculopathy with Patent Foramen Ovale

Purpose: To report a case of paracentral acute middle maculopathy (PAMM) in an otherwise healthy adult with a patent foramen ovale (PFO). Case summary: A 38-year-old male with no significant medical history presented with acute onset vision loss (20/60) in the right eye. PAMM was diagnosed based on the following findings: hyperreflective band-like lesions at the level of the inner nuclear layer on spec-tral-domain optical coherence tomography (OCT) and dendritic blacked out areas of hypoperfusion in the intermediate capillary plexus layer on OCT angiography. A systemic workup revealed a large PFO suspicious as a secondary underlying abnormality. After successful closure of the PFO, the pericapillary ischemic signs at the macula were resolved, and the patient’s visual symptoms significantly improved to 20/40. Conclusions: This report verifies the importance of an early cardiac investigation in otherwise healthy individuals with PAMM.
Developing remote sensing techniques to estimate photosynthesis and annual forest growth across a steep climatic gradient in western Oregon, USA

Waring, R.H. , Runyon, J., McCreight, R. ,Yoder, B. , Goward, S.N. & Ryan, M. 1993. Developing remote sensing techniques to estimate photosynthesis and annual forest growth across a steep climatic gradient in western Oregon, USA. In: Management of structure and productivity of boreal and subalpine forests (ed. S. Linder &S. Kellomdki). Studia Forestalia Suecica 191. 94 pp. ISSN 0039-3150, ISBN 91-576-4822-0. The upper limits to photosynthesis are set by the amount of light intercepted daily and annually by green foliage. Freezing temperatures, drought, and humidity deficits further constrain photosynthesis. The visible light intercepted and that utilized by forests distributed across an environmental gradient in western Oregon were assessed from ground-based meteorological and physiological measurements. Utilized light was converted into biomass increment and showed an annual efficiency of 1 g M.1 -1 for forests with aboveground production from <2 to 17 Mg ha' yr ' (r 2 = 0.98). We present analogues in remote sensing for all of the ground-based measurements. We illustrate how various sensors estimate: (1) solar radiation, (2) temperature, (3) drought, (4) atmospheric water vapor deficits and (5) key properties of the vegetation. Combined, these remotely sensed techniques offer a means of estimating forest growth in the Pacific Northwest and possibly, globally.
Flood event impact on pesticide transfer in a small agricultural catchment (Montoussé at Auradé, south west France)

In this paper, pesticide transfer dynamic is studied during two flood events in a small experimental catchment close to Toulouse (south west France). Thirteen pesticide molecules (herbicides, fungicides) have been analysed by multi-residue technique on filtered and unfiltered waters. The results show very high pesticide concentrations in the different fractions compared to low flow periods and to the data collected by the French institutional networks in charge of the pesticide river water pollution survey. Several molecules present concentration higher than 0.1 µg L−1 and even higher than 1 µg L−1 in the unfiltered waters. In the suspended matters the concentrations vary respectively between 0.1 and 30 µg g−1 according to the molecules and can represent 40 to 90% of the total concentration for low soluble molecules. All the molecule concentrations and fluxes increase during the flood flows and have positive relationships with the stream discharge, but hysteresis between rising and falling periods can be observed for some molecules. Pesticide concentrations in unfiltered waters and partitioning between dissolved and particulate fractions (Kd = [diss]/[part]) are controlled by dissolved organic carbon and total suspended matter. A good negative relationship can be established between log Kd and log Kow for 6 molecules.
RelaX: A Webbased Execution and Learning Tool for Relational Algebra

The relational model and especially the relational algebra is the fundament of each relational database system and thus content of almost every database lecture. Even though there exist a few tools allowing to experiment with relational algebra, a common way to learn it is still by formulating queries on paper, without the option of checking them for syntax or even executing them. To fill this gap and to support students in their learning process, we propose RelaX, a webbased tool which is capable of executing arbitrary relational algebra statements on arbitrary datasets. By drawing interactive operator trees corresponding to the queries, it is also possible to compute the final result in a step-by-step manner. Finally, RelaX is also equipped to execute SQL queries and to automatically translate them to relational algebra.
Impact of a chest support on lower back muscles activity during forward bending

The present study is based on previous research on the poor body posture of surgeons and their experienced discomfort during surgical procedures. Since surgeons have head-bent and back-bent posture during open surgical procedures, a chest support is a viable supporting principle. This support is meant to reduce lower back pain by minimising lower back muscle activity. The aim of this study is to investigate the impact of a chest support on lower back muscle activity during forward bending and to establish a possible relation between supporting force and the kind of balancing strategy a person adopts. Use of the chest support shows a significant reduction of muscle activity in the lower back and leg muscles. Within the participants three user groups are identified as “sceptical users”, “non-trusters” and “fully trusters”, each following a different balancing strategy. Since there are different kinds of users, the designed body support should offer the possibility for altering the posture and should not constrain the user to take a certain body posture.
What can Hydrography Tell Us About the Strength of the Nordic Seas MOC Over the Last 70 to 100 Years?

The flow of warm water into the Nordic Seas plays an important role for the mild climate of central and northern Europe. Here we estimate the stability of this flow thanks to the extensive hydrographic record that dates back to the early 1900s. Using all casts in two areas with little mean flow just south and north of the Greenland‐Scotland Ridge that bracket the two main inflow branches, we find a well‐defined approximately ±0.5 Sv volume transport (and a corresponding ±30 TW heat flux) variation in synchrony with the Atlantic multidecadal variability that peaked most recently around 2010 and is now trending down. No evidence is found for a long‐term trend in transport over the last 70 to 100 years.
Parsec-scale structure of quasars: dawn of the golden age?

Half a century after their discovery, the study of quasars remains one of the most fascinating intellectual challenges in astronomy. Quasars are laboratories for everything from relativity to magnetohydrodynamics and are perhaps the best available probes for cosmology. A tremendous amount has been learned about quasars and yet many of the most fundamental questions about their physics remain open. Parsec-scale observations have played an indispensable role in building up our current understanding of quasars; virtually everything we know about quasars depends on such observations. However, the finest hour for parsec scale observations may be just beginning. This is partly due to the development of highly reliable VLBI networks (which is continuing) but mostly due to the unprecedented availability of multiepoch, simultaneous, broadband observations that have long been the `holy grail' for quasar researchers.
Preparing Attitude Scale to Define Students" Attitudes about Environment, Recycling, Plastic and Plastic Waste *

The aim of this study is to introduce an attitude scale in order to define students’ attitudes about environment, recycling, plastics, plastic waste. In this study, 80 attitude sentences according to 5-point Likert-type scale were prepared and applied to 492 students of 6th grade in the Kastamonu city center of Turkey. The scale consists of cognitive, affective, and psychomotor skills domains. After the factor analysis it was found that they have 3, 4 and 5 factors accordingly. After the reliability analysis the alpha values for cognitive, affective and psychomotor scales are . 854, . 871 and . 826 respectively. As a result, it is found that the scale can be used to define cognitive, affective and psychomotor attitudes.
Alkylating anticancer agents and their relations to microRNAs

Alkylating agents represent an important class of anticancer drugs. The occurrence and emergence of tumor resistance to the treatment with alkylating agents denotes a severe problem in the clinics. A detailed understanding of the mechanisms of activity of alkylating drugs is essential in order to overcome drug resistance. In particular, the role of non-coding microRNAs concerning alkylating drug activity and resistance in various cancers is highlighted in this review. Both synthetic and natural alkylating agents, which are approved for cancer therapy, are discussed concerning their interplay with microRNAs.
Reputation , Contract Renegotiation and Price Rigidity

This paper shows that reputation concerns can explain the reluctance of sellers to initiate contract renegotiation, which can lead to price stickiness and breakdown of ex-post efficient trade. Using a novel audit methodology, we find that small businesses in India do not charge higher prices when faced with cost shocks or increases in bargaining power. Instead they either fill the order without a price increase or forgo it altogether. However, when customers offer higher prices, sellers are significantly more likely to accept the order. The reluctance to renegotiate increases with prior interactions and when reputation costs are more important. *Iyer: Imperial College, email: riyer@ic.ac. uk; Malenko: MIT Sloan School of Management, email: amalenko@mit.edu; Schoar: MIT Sloan School of Management and NBER, email: aschoar@mit.edu.

From experience to knowledge in professional IT management education: exploring the applicability of classroom learning to real-life contexts

Abstract By understanding knowledge to be performative – a ‘dynamic and ongoing social accomplishment’, rather than a representation or commodity – we view knowledge, or more accurately ‘knowing’, as a capability that emerges from, is embodied by, and embedded in recurrent social practices. The fluent knowing-in-practice that distinguishes an expert practitioner from a novice is developed through the reflexive interaction of the practitioner with their peers and their real-life work practices . Our key aim in this research was to explore whether it is possible for the abstracted classroom setting to approximate real-life work contexts, thereby enabling the active physical, mental, and emotional engagement of learner/practitioners within their community of practice, which have been demonstrated in the literature to be central to learning. How might training programmes actively engage learners in this way? We explored these questions through focus groups and interviews with participants on a professional IT management training programme and found that real-life contexts can be approximated to an extent, such that learner/ practitioners are enabled to learn from their own and each other’s experience of addressing issues in relation to IT management.
Acute effects of static stretching on muscle strength

Acute effects of static stretching on muscle strength Study aim: To assess the effects of static passive maximal stretching on muscle performance in order to clarify the existing controversies. Material and methods: Two randomly selected groups of the Brazilian Air Force personnel were studied: experimental (n = 15), subjected to 3 bouts of static passive stretching exercises of wrist flexors and extensors (beyond a mild discomfort). Every bout lasted 10 s and was followed by a 30-s rest. The control group (n = 15) performed no exercises. Muscle strength was measured with a handgrip dynamometer before and 20 min after the test. Results: Subjects from the experimental group had the pre-exercise handgrip strength significantly higher than postexercise (by about 7%; p<0.01). No significant decrease was noted in the control group. Conclusions: Static passive stretching induces decreases in muscle strength.
Analysis of Correlation between Climate and Stroke

Aim: The aim of the research is to determine characteristic of the correlation between climate and stroke through the analysis of relevant documents. Methods: We found 115 researches of temperature and season on stroke mortality/incidence and these were categorized according to location, meteorology, date span, data source and research sites’ latitudes. We divided the globe into 5 temperature zones based on latitude ranges: 0 10, 10 23.5, 23.5 40, 40 50, and >50 degrees, and allotted a zone to each country. Stroke mortality by five temperature zones was calculated per 100,000 people. Results: 70% of the researches came from latitudes greater than 40 degrees with 92% of researches located in Europe, USA, and Asia. The mortality range was 42 63 per 105 individuals within latitudes 0 40 degrees. In latitudes 40 66.5 degrees, a linear upward trend (y = 69.82x − 22.823, R2 = 0.99) was noticed. More than 75% of the research reports indicated a negative correlation between climate and stroke, and the proportion was almost 6 and 7 times greater than that of the fluctuation and non-correlation, respectively. The most frequently used research methods were regression analysis and time series analysis. Conclusion: All of the research results confirmed that lower temperature is associated with higher mortality and incidence of stroke, while higher latitude is correlated with higher stroke mortality, consistent with the temperature zones.
