Convective Heat Transfer Flow of a Viscous Electrically Conducting Fluid ina Non-Uniformily Heated Axially Varying Pipe

We analyse the effect of radiation on combined heat transfer of an electrically conducting viscous fluid in a nonuniformly heated corrugated pipe in the presence of a constant heat source. A non –uniform temperature is maintained on the boundary. Taking the slope d of the boundary of the pipe as perturbation parameter, the equations governing the flow , heat transfer and magnetic induction have been solved. The velocity and temperature have been evaluated for variations in the different governing parameters. The effect of the various governing parameters on flow, heat transfer has been exhibited through various profiles of velocity, temperature distributions.
The emergence of productive non-medical -itis: corpus evidence and qualitative analysis

No natural language has a closed vocabulary (Kornai 2002). In addition to mechanisms to add to the base vocabulary, like borrowing, shortening, creativity etc. the productivity of morphological processes can form new complex entries. Some word formation processes can be used to form new words more easily than others. This fact, called morphological productivity, has been recognized for a long time and discussed from many points of view (see for example Aronoff 1976; Booij 1977; Baayen and Lieber 1991; Baayen 1992; Plag 1999; Bauer 2001; Baayen 2001; Nishimoto 2004). This paper is concerned with evidence for different aspects of morphological productivity. Our claim is that the problem of productivity can only be understood when different kinds of evidence – quantitative and qualitative – are combined. We will try to understand more about the interaction of qualitative and quantitative aspects of morphological productivity. We illustrate our claim by looking at a morphological element that has not received much attention in morphological descriptions yet: German -itis.1
New Approaches to Work Wear

In the article the research results on the safety of workers in the greenhouses have been presented. The problem of improving the environmental protection has been considered due to the analysis of production risks of work in the greenhouse. The authors have defined the topography of the influence of hazardous factors of production on the parts of workers' body based on which the recommendations for making up a set of work wear together with means of protection have been worked out. The proposed kinds of protection are based on standard methodics and approaches as well as on the implementation of modern state-of-arts technologies.
THE EFFECT OF MASKER TYPE AND WORD POSITION ON IMMEDIATE SENTENCE RECALL

Noise maskers primarily result in energetic masking, whereas speech maskers create additional interference due to linguistic and acoustic similarities to the target (informational masking). Factors that facilitate stream segregation can greatly reducethe extent of informational masking. However, stream segregation often takes time to develop. In Experiment 1, nonsense sentences with 3 keywords were presented against a background of speech-spectrum noise or two-talker nonsense speech. With the speech masker, accuracy increased with word position. With the noise masker, accuracy did not vary systematically with word position. In Experiment 2, we noise-vocoded the speech masker using three bands to preserve envelope information while disrupting fine structure cues and minimizing semantic content. Here, performance was similar to that found with the noise masker. The results suggest that the ability to track a target sentence in conditions of informational masking improves as the target utterance unfolds over time.
The Use of Gross Efficiency Coefficients in Cyclists’ Endurance Tests

The efficiency of energy conversion of aerobic metabolism to external work is of great importance to sports exercise. Despite this fact, gross efficiency (GE) is not commonly used as a parameter in the assessment of cyclists’ exercise ability. It is also known that road cyclists traverse most of their route at a work intensity below the anaerobic threshold (AT). We tried to examine the relationship between the standard aerobic parameters used for defining the endurance of cyclists and GE, measured just below the anaerobic threshold. Fifty cyclists were subjected to a progressive test. Work done and the basic respiratory and circulatory parameters were measured. Gross efficiency was calculated at work intensity just below AT. We observed a very low correlation (R = –0.137) between GE (24.9 ±2.06) and maximal oxygen uptake (VO2max) – 63.8 ±6,27 ml × kg–1 × min–1. The strongest correlation (R = –0.258) was recorded between GE and the percentage of maximal oxygen consumption (58.9 ±7.0%) for the load prior to the occurrence of the anaerobic threshold. The weak, but existing correlation between GE and selected respiratory and circulatory parameters may suggest that GE provides unique and independent information about the examined athletes.
The Sex Ratio Transition in Asia

This article adopts a comparative perspective to review the recent increase in the sex ratio at birth (SRB) across Asia. It first describes and compares the most recent birth statistics in Asia in order to identify commonalities in the gradual rise of SRBs observed from Armenia to South Korea. This comparison provides the basis for identifying specific transition patterns in the changes in SRBs. Their recent rise is then interpreted in a social and historical framework borrowed from fertility decline and based on three preconditions: access to sex-selection technology, preference for male births, and pressure from low fertility. On a broader plane, the process of growing imbalances in the sex composition of the population gives rise to a tragedy of the commons. This article indicates the factors that appear most likely to trigger a turnaround in this transitional demographic situation and to facilitate a return to biologically normal sex ratios in the future.

A new protosuchian crocodile from the Upper Triassic Elliot Formation of South Africa

A new protosuchian crocodilian, Baroqueosuchus haughtoni from the Upper Triassic or Lower Jurassic Elliot Formation of the Orange Free State is the most primitive protosuchian crocodilian known. There are no contacts between the quadrate and opisthotic or below the crania-quadrate canal, the internal carotid arteries were not enclosed in separate foramina and the basicranium was flat, with the basisphenoid being broadly exposed on the base of the skull. The basic diagnosis of the Order Crocodilia is discussed and a new diagnosis is offered based upon cranial anatomy.
Growth-Indexed Bonds in Emerging Markets: a Quantitative Approach

In the aftermath of sovereign defaults and financial crises in the 1990s, there have been calls for the widespread use by sovereigns of equity-like financial instruments, in particular, of GDP-indexed bonds. This paper calibrates a general equilibrium model with endogenous default to a typical emerging market economy and evaluates whether the existence of a (partially) GDP-indexed bond, as proposed in the literature, is quantitatively important in what concerns spreads, debt to GDP ratios, and the likelihood of default

Two-band luminescence from an intrinsic defect in spherical and terraced MgO nanoparticles

Luminescent defect centers in wide bandgap materials such as MgO are of great interest for science and technology. Magnesium oxide nanocubes obtained by the self-combustion of Mg metal have long exhibited only a broad 2.9 eV cathodoluminescence band owing to oxygen vacancies (F centers). However, in this work, a room-temperature ultraviolet 4.8 eV cathodoluminescence band has been observed coincident with a 2.5 eV band of the same intensity from an unexplored intrinsic defect in MgO terraced nanocubes and nanospheres produced from Mg metal combustion in an H2/O2 flame. Synchrotron radiation excitation spectra reveal that the excitation energy at the onset of both bands is just above the bandgap energy of 7.7 eV, where electrons and holes are generated. We determine that a defect, responsible for both emission bands, creates proximal anion-cation vacancy pairs named P centers that may appear instead of F centers because of changes in the MgO nanoparticle growth conditions.
IWFMS: An Internal Workflow Management System/Optimizer for Hadoop

The scale of jobs running on parallel computation platform such as Hadoop is increasing quickly, thus workflow engines that manage data processing jobs have become increasingly important. However, traditional workflow management systems are mostly outsiders to Hadoop and cannot fulfill many important requirements, such as user constraints and scheduling optimizations. In this paper, we present IWFMS, an internal workflow scheduling system/optimizer that 1) Manage the resource allocation and execution of jobs in workflows to achieve higher efficiency, 2) Schedule workflows to meet a much richer set of user constraints such as deadlines, priorities and workflow trigger events. We discuss the architecture of its key components and evaluate its features and performance.
Use of Acoustic Emission for Testing Resistance of Hooves

DOSTÁL PETR, HAVLÍČEK ZDENĚK, KRATOCHVÍLOVÁ LUCIE. 2018. Use of Acoustic Emission for Testing Resistance of Hooves. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 66(1): 0029 – 0033. This paper deals with the possibility of using an acoustic emission method for testing tensile strength of hooves. By using the acoustic emission (AE) method, we are able to locate degraded areas in hooves and then estimate the extent of degradation. In the experimental part, a sensor was used to record the emission signals, the measured data were processed and analysed, and the response of hooves to the applied mechanical load over time was monitored. Altogether, three samples were tested on the Zwick Z050 / TH 3A materials testing machine and simultaneously the acoustic emissions were measured during testing.
A LOOP-SHAPING APPROACH TO LOAD REDUCTION

The use of active controls has shown to be of substantial help in supporting the increasing size of wind turbines by reducing peak stresses and fatigue loads. In this respect, this paper proposes the use of intuitive frequency-based control strategies for reducing loads in wind turbine blades equipped with multi-input multi-output (MIMO) active flow controllers. For that purpose, a loop-shaping approach is considered for analysing the dynamic of actively controlled wind turbine blades. Preliminary aeroelastic simulations are carried out to validate the results. It is shown that the MIMO vibration control problem can effectively be decomposed into a number of decoupled single-input single-output control problems because of the strong correlation between the dominant aeroelastic blade dynamics and actuator deployments. As a result, it is demonstrated that classical single-input single-output control systems can perform as efficiently as MIMO controllers for damping the aeroelastic dynamics of wind turbine blades.
The degree of protection different ants (Hymenoptera: Formicidae) provide aphids (Hemiptera: Aphididae) against aphidophages

Aphids play an important role in the life of many ant species supplying them with energy-rich carbohydrate food and in exchange receiving some degree of protection from natural enemies. This study focused on the degree of protection different ants provide myrmecophilous aphids (Hemiptera: Aphididae) in multispecies ant communities. Field investigations were carried out in steppe and forest plant associations in Siberia. The potential level of aggressiveness of six ant species (Formica rufa Linnaeus, F. pratensis Retzius, Lasius fuliginosus (Latreille), L. niger (Linnaeus), Camponotus saxatilis Ruzsky and Myrmica rubra Linnaeus) towards imagines and larvae of ladybirds and lacewings and larvae of hoverflies was tested in the laboratory. A comparative analysis of the occurrence of aphidophages in colonies of the aphid Chaitophorus populeti Panzer and of all aphid-symbionts tended by different ants in the study area has shown that the degree of protection of myrmecophilous aphids from natural enemies significantly differs among ants and is positively correlated with ant colony size. On the whole, the degree of protection of myrmecophilous aphids from aphidophages depends both on the potential level of aggressiveness of ants and their foraging strategy when collecting honeydew (degree of specialisation among honeydew collectors). As the dominant ants Formica s. str. were the most aggressive and provided aphids with the highest degree of protection, we suppose that these ants have the most important influence on the survival of the symbionts in multispecies ant communities whereas the other ants, which live in small colonies of about 102-103 workers, appear at least partially to take advantage of the mutualistic relationships of the dominant ants.
Structural Model of TaNAM-B1 Transcription Factor from Wheat ( Triticum aestivum ) Insight into the Nutritional Grain Quality

Wheat is a propitious crop which renders several health benefits, but the modern wheat lacks essential micronutrients like zinc and iron. In this paper, various bioinformatics tools and molecular modeling approaches have been embodied for the development and exploration of structure and various properties, respectively. The NAM-B1 gene is a NAC transcription factor which plays an essential role in the translation machinery. It is also responsible for maintaining the nutritional seed grain quality in wheat. NAM-B1 gene is accountable for the Fe and Zn concentration in wheat and is also held responsible for delayed senescence in the crop by three weeks. In this study, we have developed the structural model of the NAM-B1 protein using the structure of 3ULX as template by Modeller 9.12. The resultant model was further processed and refined using various tools such as PROCHECK, ProSA, Verify3D and RMSD. As a result, the model developed was found to be conceivable with 62% a.a sequence identity with the template. Investigation revealed that conserved region found was accountable of the response generated during the improvement of the nutritional quality of grain. TaNAM-B1 plays an ingenious role in leaf senescence and abiotic stress tolerance in plants.
Classification with ClassOverlapping: A Systematic Study

Class overlapping has long been regarded as one of the toughest pervasive problems in classification. When it is combined with class imbalance problem, the situation becomes even more complicated, with few works in the literature addressing this combinative effect. In this paper, we pay a systematic study on the class overlapping problem and its interrelationship with the class imbalance problem. Five widely used classifiers and three overlappingclass modeling schemes are employed for the comparative study. Extensive experimental studies on various realworld data sets reveal that: (1) The separating scheme is the best among the three schemes; (2) The distancebased classifiers are more sensitive than the rule-based ones to the class overlapping problem; (3) As the increase of the class imbalance ratio, the separating scheme showed higher improvements to the classification performance, in particular for the well-known SVMs.
Evaluation of Wound Healing Property of Karanja Patra Ghana - Water Extract of Pongamia pinnata Linn Leaf

Karanja, Pongamia pinnata Linn is traditionally used to treat various skin disorders, including wounds. It is widely used in Ayurveda as an effective and readily available treatment of various wounds. This study was aimed at investigating the healing efficacy of Karanja Patra Ghana - water extract of Pongamia pinnata Linn leaf. Swiss albino rats were divided into four groups, two control groups and two treatment groups consisting of excision wound healing model and incision wound healing model. In excision wound, percentage of wound contraction and period of epithelization were the parameters for the study and this was achieved by using planimetry (Morton and melone method). In incision wound tensile strength was the parameter and this was achieved by tensiometry (Hunts et al. method). Statistically treatment group showed better wound healing in terms of epithelization and tensile strength. It may be concluded that Karanja Patra Ghana - water extract of Pongamia pinnata Linn leaf formulated is effective in the treatment of wounds and thus supports its traditional use.
Factors affecting students ' satisfaction with inquiry - based learning in science and technology class

Inquiry-based learning is inductive teaching method which was very popular in 1960's, but in nowadays science and technology was not extended so much. Method differs from traditional instructional methods in developing a) students' self-regulation and efficacy, b) critical and logical thinking, and c) problem solving skills. European Union seventh framework project titled Chain Reaction makes effort to promote and exploit this method to science and technology with pre-prepared four content topics in order to collect necessary data for its quality assessment. Active learning was carried out at open learning activities of technology days at five Slovenian elementary schools. The sample consists of 260 eighth- and ninth-grade students. Inquiry-based learning was guided by 5E learning cycle model, where students' satisfaction was assessed when learning was accomplished. Multiple regressions revealed key factors affecting student satisfaction, while variance analysis defines significant impact with effect size. Satisfaction factors were revealed, beta weights in parentheses: content (0.29), physical learning environment (0.27), reactions (0.26), learning process (0.26) and learning material (0.25). Learning difficulty was judged to be moderate. Instructional model suits to male and female students evenly, while green heating learning theme needs to be modified accordingly.
Molecular identification of Anopheles gambiae sensu stricto Giles (formerly Anopheles gambiae Savannah Form) in Kamuli District, Uganda

Anopheles gambiae sensu stricto Giles (formerly A. gambiae S molecular form), the largely anthropophilic species, is reportedly the most important malaria vector in Uganda among the A. gambiae complex species. Indoor and outdoor human-biting mosquitoes were caught for four consecutive nights in each of 48 households in Kamuli district using human-baited bed net traps for subsequent identification of the principal Anopheles sibling species responsible for transmitting malaria. Sibling species under the A. gambiae complex were characterized by polymerase chain reaction using species specific single nucleotide polymorphism (SNPs) in the intergenic spacer region (IGS) with primers specific for A. gambiae s.s. , Anopheles arabiensis, Anopheles melas, Anopheles merus and Anopheles quadriannulatus . Molecular forms of the A. gambiae s.s. were further discriminated using primers specific for Mopti and Savannah forms. Out of 300 A. gambiae s.l. amplified, 98% (n= 294) were A. gambiae s.s. Out of 142 A. gambiae s.s. samples analyzed for molecular forms, 78.9% (n=112) were identified as A. gambiae s.s. Giles ( A. gambiae Savannah (S) form, while the other 21.1% were not identifiable. the presence of A. gambiae s.s. Giles in Kamuli was also reported. Considering the anthropophilic, endophagic and endophilic behavior of A. gambiae s.s. (and of the molecularly similar A. gambiae s.s. Giles), the combined use of insecticide-treated nets (ITNs), indoor residual spraying, larval source management and improved house design in the context of integrated vector management, may be the appropriate vector control strategies in the area. There is also need for regular monitoring of the vector species composition, distribution and behavior for proper planning of appropriate vector control interventions in the future. Key words : Sibling species, molecular forms, Anopheles gambiae complex, anthropophily, IPM.
Curvature cones and the Ricci flow

This survey reviews some facts about nonnegativity conditions on the curvature tensor of a Riemannian manifold which are preserved by the action of the Ricci flow. The text focuses on two main points. First we describe the known examples of preserved curvature con-ditions and how they have been used to derive geometric results, in particular sphere theorems. We then describe some recent results which give restrictions on general preserved conditions. The paper ends with some open questions on these matters. The Ricci flow is the following evolution equation:

Optimal Operating Policies for a Multinational Company under Varying Market Economics

This paper proposes a mathematical programming model for Multi-National Corporations (MNCs) by considering both the flexibility of exchange rate and market price uncertainties. The results show that the factory in a host country should supply the products demanded by the home country for the next period when exchange rate decreases. The quantity of products being produced and shipped should be adjusted according to the variation of market-price. Conversely, a MNC in the host country should produce products ahead of time when exchange rate increases and must adjust quantity of production and inventories according to the variation of market-price.
Valuing the User Experience in Human-Computer Interaction: the Respected User Manifesto

There is a no-man's land between how the Graphical User Interfaces are typically conceived, designed and engineered in desktop applications and mobile apps, and what users actually expect: it's where the users' experience, expectations, training, habits, mental attitude come into play. New software versions add features, change the GUI layout, behavior and environment for innovation and marketing reasons, but in doing so they often disregard the value of the user experience: all the user can do is accept the new situation and trying to adapt. To make things worse, customization options are usually limited when it comes to restoring the previous environment, and downgrading restrictions in software licenses also apply. Background services may also start at the worst time, monopolizing the system against the user's will, causing frustration and possibly more serious problems due to service unavailability. In short, there's a grey cross area in software design and deployment where the user is not fully respected as a person whose experience is intrinsically a value worth preserving.In this paper we analyze and discuss some common situations from different scenarios, and exploit them to extract some golden rules for a more respected software user - the Respected User Manifesto.
