Ukrainain Swearing in the Mirror of German Translation
Authors: Tkachivska M.
Published: October 2015

The article deals with the problem of swearing and its translation from Ukrainian intoGerman. It provides the analyses of the previous researches covering the topics “foul language”,“obscene language” and “swearing”. Swearing is a language taboo that conveys the negativeenergy a speaker wants to get rid of by the means of shifting it on the recipient. It is not always therecipient who is the addressee of the swearing, since language taboo includes the usage of anaddress-free swearing, the latter one belonging to the parenthetic words which are languageincrustations and which do not carry semantic meaning. But in the language there are also otherobscene words with the semantically-lowered connotation. The article reveals the differences in theusage of swear language by different nations, it also provides the comparison of the Ukrainian,Russian and German swearing. It is pointed out that Russian obscene language is more connectedto the rude names of genitals, sexual intercourse and sexual deviations, but it is less connected tothe physiological ejections. The article studies the influence of the Russian culture on other nations’cultures, including the Ukrainian one. In the Ukrainian and German languages, contrary to theRussian language, obscene words are mainly connected to the physiological ejections (scatologicalhumour). After careful study of the certain scholars works the author of the article alsodemonstrates the ways obscene words come up in the Ukrainian language. The article alsodemonstrates the ways of translation of the swearing the examples being provided from the fromthe post-modern literature works.

Nonlinear Frequency Conversion Performance of AgGaSe2, ZnGeP2, and CdGeAs2
Authors: Schunemann P.G. , Schepler K.L. , Budni P.A.
Published: October 2015

In recent years, chalcopyrites have distinguished themselves as the nonlinear optical materials of choice for mid- to far-infrared (ir) laser applications. In particular, AgGaSe2, ZnGeP2, and CdGeAs2 have demonstrated the highest conversion efficiencies and output powers in the wavelength range beyond 4 μm. The superior performance of these crystals arises from their high nonlinear optical coefficients (39 pm/V, 75 pm/V, and 236 pm/V, respectively), their relatively large birefringence (sufficient for phase matching), and advances in crystal growth and processing that have improved transparency and eliminated cracking.

The two most direct approaches to generating laser output in the mid-ir (in particular the 3–5-μm atmospheric transmission window) are (1) shifting the output of a solid-state laser to longer wavelengths via optical parametric oscillation (OPO), or (2) doubling the frequency of a CO2 laser (9–11 μm) via second-harmonic generation (SHG). The OPO approach offers the advantage of tunability combined with potentially more compact and efficient solid-state lasers, whereas the SHG approach benefits from the greater maturity of high-power CO2 laser technology. A third process, difference-frequency generation (DFG), is also a 3-wave interaction similar to OPO that can be used to mix two photons (from two lasers or from an OPO) to produce longer wavelength photons (corresponding to the small difference frequency) over a large spectral range. The optimum chalcopyrite crystal (AgGaSe2, ZnGeP2, or CdGeAs2) for a given approach depends on a complex combination of material parameters described in the sections that follow.

Authors: Sunaryanto Rofiq , Mahsunah Anis Herliyani
Published: October 2015

Identification and antimicrobial assay of indegenous marine Streptomyces have been conducted. Samples were obtained from culture collection of Biotech Center, Agency for the Assessment and Application of Technology (BPPT). They were originated from several Indonesian seashores including Pelabuhan Ratu, Pangandaran, Manokwari, Pulau Seribu, Garut, Bangka, Banjarmasin, Belitung, Cirebon, and Palu. Isolates stored as glycerol stocks were inoculated onto HV (Humic acid vitamin) agar and incubated for 5 days at 30 °C. Each colony was cultivated using yeast-peptone medium and then extracted by butanol. Antimicrobial activities were monitored by the agar diffusion paper-disc method against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Bacillus subtilis ATCC 66923, Pseudomonas aeruginosa ATCC 27853, Candida albicans BIOMCC 00122 and Aspergillus niger BIOMCC 0013. Molecular identification of Streptomyces was carried out based on 16S rRNA gene analysis. Our research results showed that 71 isolates obtained from several Indonesian seashore were identified as 57 different Streptomyces species. Fifty of them showed antimicrobial activity. Twenty three isolates inhibited B. subtilis ATCC 66923, 14 isolates inhibited S. aureus ATCC 25923, 24 isolates inhibited C. albicans BIOMCC 00122 and 26 isolates inhibited A. niger BIOMCC 0013 and there was no active isolates inhibited the growth of E. coli ATCC 25922 and P. aeruginosa ATCC 27853. Phylogenetic analysis showed that Streptomyces isolates originated from the same geographically region was not necessarily grouped into the same cluster. Likewise a phylogenetic cluster may contain isolates of the same Streptomyces species, but from geographically different locations.
Capturing Natural Product Biosynthetic Pathways from Uncultivated Symbiotic Bacteria of Marine Sponges Through Metagenome Mining: A Mini-Review
Authors: Uria Agustinus Robert
Published: October 2015

Symbiotic bacteria associated with marine sponges have frequently been proposed as the true producer of many bioactive natural products with potent anticancer activities. However, the majority of these complex symbiotic bacteria cannot be cultivated under laboratory conditions, hampering efforts to access and develop their potent compounds for therapeutic applications. Metagenome mining is a powerful cultivation-independent tool that can be used to search for new natural product biosynthetic pathways from highly complex bacterial consortia. Some notable examples of natural products, in which their biosynthetic pathways have been cloned by metagenome mining are onnamide A, psymberin, polytheonamides, calyculin, and misakinolide A. Subsequent expression of the pathways in easily culturable bacteria, such as Escherichia coli, could lead to the sustainable production of rare promising natural products. This review discusses principles of metagenome mining developed to gain access to natural product biosynthetic pathways from uncultured symbiotic bacteria of marine sponges. This includes detecting biosynthetic genes in sponge metagenome, creating large metagenomic library, rapid screening of metagenomic library, and clone sequencing. For many natural products made by modular polyketide synthases (PKSs) and hybrids with non-ribosomal peptide synthetases (NRPSs), their biosynthetic pathways as well as structures of final products can be predicted with high accuracy through bioinformatic analysis and sometimes combined with functional proof. Further metagenome sequencing integrated with single-cell analysis and chemical studies could provide insights into the remarkable biosynthetic capacity of uncultivated bacterial symbionts, thereby facilitating the discovery and sustainable production of a wide diversity of sponge-derived complex compounds.
"Once Upon a Time...": When Prehistoric Archaeology and Folklore Converge
Authors: Silva Fabio
Published: October 2015

This paper addresses the issue of congruence between archaeological narrative and folktale, and tentatively explores its implications for our understanding of the deep past, as well as of present-day folklore. Similarities between a folktale that explains the name of Serra da Estrela, a mountain range in central Portugal, and the material record of Neolithic Iberian dolmen builders of the nearby Mondego valley suggest that the prehistoric reality might be the origin of the tale. This congruence, an example among many others, has implications for the understanding of folklore, social memory and ethno-history. However, for this to occur, this paper argues that folklore needs to be looked at in the longue durée, and its origins and transformations better understood. The paper concludes with a discussion of several points raised by this case study that should be considered in the development of a methodology for congruous archaeology/folklore studies.
“Green is Where it’s At!” Cultivating Environmental Concern at an African American Church
Authors: Baugh Amanda J.
Published: October 2015

Since the 1990s much 'religion and ecology' scholarship has sought to identify theological, ethical, and scriptural resources that suggest all religions teach their followers to protect the earth. Case studies have focused primarily on success stories that demonstrate how religions can contribute to a more sustainable future, but religion and ecology scholarship has paid inadequate attention to cultural complexities involved with cultivating environmental concern in religious communities. This article aims to address some of those neglected factors. A bible study on food, faith, and the environment held at an African American church in Chicago offers a glimpse into a window for exploring how assumptions about ethnicity and class influence the presumed ‘greening’ of American religion. I argue that efforts to ‘green’ American religion have relied not only on religious teachings, but also on latent assumptions about ethnicity and class.
Religion and Art Behavior—A Theory and an Example
Authors: Rennie Bryan
Published: October 2015

Enough has been written on the cognitive and evolutionary bases of both art and religion to permit a theoretical understanding of these closely related behaviors. My argument is that religion and art are descendants of a common ancestral behavior that cannot be identified as either one or the other but has identifying features of both. It is my contention that such an understanding facilitates an improved comprehension of the history of religion as well as a coherent theoretical explanation of religious pluralism. As an example of the application and implication of this theory I will undertake a brief analysis of Biblical Prophecy as a complex of art forms bearing significant similarities to contemporary postcolonial literature and street theater. Both complexes communicate individual emotional responses to the environment in such that they are transmitted and retained in the local culture and contributeory to assured and persistent behavior.

Authors: Teixeira Paula Cristina , Matos José Manuel , Domingos António
Published: October 2015

Using the paradigm of activity theory, the central problem of this paper (This paper is supported by FCT – Foundation for Science and Technology (Project “Promoting Success in Mathematics” – PTDC/CPE-CED/121774)) is the characterization of the processes through which teachers replicate, adapt, and improvise tasks of textbooks with use of technological resources (CD-ROMs and web portals). In other words, we seek to identify teachers’ use of schemas in actions mediated by these technological elements. Two of us accompanied Portuguese secondary mathematics teachers in the assessment of learning tasks involving the use of new technological resources and the analysis of feedback of teaching performance after implementation in the classroom. This feedback was obtained from their peers, trainers and teachers’ reflection on the actions in classes and occurred during the sessions of the training activities. The study shows that teachers plan coordinated tasks that integrate technology resources and apply them in classes adjusting them to the technological environment of their schools. However, some difficulties in interpreting feedback are revealed.
The Attitude of Future Primary School Teachers towards National Values
Authors: Abramauskienė Jolanta
Published: October 2015

In the context of world globalization nowadays, issues of nationality arise again. They become relevant in the condition of country integration and mixing of nations. The current problem is important enough to be researched, as Lithuania is becoming a more cosmopolitan state, the need for usage of foreign languages increases and nations internationalize. The aim of the research is to explore future primary school teacher’s attitudes towards national values. There were 93 students questioned in the 2012 at Lithuanian University of Educational Sciences. The analysis of the research results show that students have all the national values: they are proud of their nationality, religion, traditions, proud of their beautiful language, their honourable Lithuanian state, beautiful nature and architectural buildings. Majority of the students said that it’s very important residential place, because of its beautiful nature, their relationship with the people living here, because it’s theirs birthplace, because of architectural monuments and their parents’ real estate. However, more than half of the students doubt it they will be able to find good job based on their education, more than a third said it’s difficult to live here. Worrying factor could be focusing on the personal, material issues, not facing essential issues. Nowadays young people are more focused on personal values rather than societal values. The research displays that the majority of the students knows Lithuanian anthem, believes that it is very important to respect Lithuanian flag, to celebrate religious holidays and ethnic festivals, but only every five students expressed positive attitudes toward of folk songs, representing national values as a phenomenon. Some respondents indicated not very profound meaning of national values: they know only few folk songs, can’t tell the ethno music importance nowadays education.

(Im)possibilidade de narrar deus numasociedade pósmetafísica:plausibilidade de um discurso alternativoa origem da vida
Authors: Fraiberg Machado Márcio
Published: October 2015

Esse artigo pretende refletir sobre como a ciência vem sendo construída e divulgada. Essa discussão tem como base o livro didátio. Amparado pelo governo, é amplamente distribuído em todo o território nacional. Para a maioria da população brasileira, seu conteúdo será a noção norteadora de sociedade e de seus conceitos, visto que é pequena a parcela que voltará a discutila nas universidades. Percebo falhas na divulgação de seu conteúdo através do livro didático. No quesito ciência, os livros informam um paradigma dominante que precisa ser analisado, pois a ciência é descrita como positivista, apoiada pelo método científico e rigor matemático. Mas o que dizer a respeito da origem da vida? Que elementos fornecem plausibilidade à existência de outro discurso que não o aceito pela academia? É na sala de aula que esse debate se amplia, pois os alunos vem municiados por artigos na internet e, muitos, encontram guarita em seu professor, imbuído de grande fé, mantendo o discurso criacionista ainda vigente, nos obrigando a questionar: Que elementos dão plausibilidade a esse cenário?
Las variables complejas en investigaciones pedagógica

Published: October 2015

Las investigaciones pedagógicas generalmente abordan fenómenos que conducen al estudio de variables complejas. Por tal motivo, dichas variables deben ser operacionalizadas, proceso que transita por la identificación de la variable, de sus dimensiones, indicadores e índices, los que permiten traducir la variable teórica en propiedades observables y/o medibles. Sin embargo, existen insuficiencias en los estudiantes de postgrado para realizar correctamente la operacionalización de las variables en sus tesis de maestrías o doctorados, lo cual influye negativamente en la calidad de los instrumentos elaborados posteriormente. Por ello, el objetivo de este trabajo es presentar la metodología de este proceso mediante ejemplos ilustrativos.
Correlation of Neopterin and TNF-alpha with Asymmetric Dimethylarginine in Metabolic Syndrome
Authors: Yuniarty Dedeh , Santoso Anwar , Arif Mansyur
Published: October 2015

BACKGROUND: A large number of obesity in the community increases the incidence of Metabolic Syndrome (MetS) that can increase the risks of heart disease, diabetes, and stroke. One of the possible causes of stroke is atherosclerosis. Atherosclerosis is initiated by the incidence of inflammation and endothelial dysfuction. Atherosclerosis is involved in an ongoing inflammatory response. At the beginning of atherosclerosis, when the endothel become inflamed, it expresses adhesion molecules  that attract monocytes. The monocytes then migrate into the intima due to endothelial dysfunction. Activation of macrophage occurs in the process of inflammation as the earliest type of lesion of atherosclerosis. In this study, monocyte/macrophage activation is marked by Neopterin. In other process of atherosclerosis, vascular nitric oxide (NO) activity has a role as a potent endogenous vasodilator. In regulating the vascular tone, NO has a role to suppress vascular smooth muscle proliferation, inhibit platelet adhesion and aggregation, and interferes with the leukocyte-endothelial cell interaction. In MetS, hypercholesterolemia decreases NO activity. Asymmetric Dimethylarginine (ADMA) has been characterized as an endogenous, competitive inhibitor of NO synthase. In this study, the incidence of endothelial dysfunction is marked by ADMA. The aim of this study was to discover the role of Neopterin in MetS patients by evaluating the correlation between Neopterin and ADMA in MetS through tumor necrosis factor (TNF)-α or direct line.METHODS: The study was cross sectional on 64 males with MetS aged 30-65 years. The measurements of TNF-α concentrations was done, respectively.RESULTS: Neopterin concentration correlated with Log TNF-α concentration (r=0.311, p=0.012). There is no significant correlation between Neopterin and ADMA (r=0.012, p=0.930); ADMA and Log TNF-α (r=0.029, p=0.821).CONCLUSIONS: There is no significant correlation between Neopterin and ADMA through TNF-α or direct line.KEYWORDS: MetS, Neopterin, ADMA, NO, TNF-α

Authors: Hariyanto Hori , Butar Butar John , Lawrence Gatot Susilo , Suhadi FX Budhianto , Tanra Andi Husni
Published: October 2015

BACKGROUND: β-endorphin plays a role in the descending pain control in the central nervous system. Central sensitization may be involved in the generating and maintenance of osteoarthritis (OA) pain. However, the correlation between β-endorphin and pain severity in OA has shown conflicting results. The aim of this study was to investigate the association between plasma β-endorphin and the severity of the disease. METHODS: This study was an observational cross-sectional study carried out on 60 female subjects with knee OA who fulfilled the inclusion criteria. Plasma β-endorphin was measured by a commercial enzyme-linked immunosorbent assay (ELISA) kit. Osteoarthritis knees were classified by the Kellegren-Lawrence (KL) grading (1-4) criteria. The Western Ontario McMaster University Osteoarthritis (WOMAC) scoring method was used to assess self-reported physical function, pain and stiffness. RESULTS: The mean of the participants' ages was 58 years old, ranging from 42 to 83 years. Overall, more than 70% of the participants were overweight with a mean of body mass index (BMI) of 27.59. More than 54% of the participants were diagnosed of having KL grading 3 or 4. Plasma β-endorphin was correlated inversely with the WOMAC subscale of stiffness (r=-0.286, p=0.0311), but no correlation was noted with the WOMAC subscale of pain and physical activity. There was no significant difference of the mean of plasma β-endorphin among the KL gradings. CONCLUSIONS: Plasma β-endorphin is associated with better WOMAC total score and stiffness subscale, but not associated with KL grading of OA.

Context dependence of maternal effects: testing assumptions of optimal egg size, differential, and sex allocation models
Authors: Krist Miloš , Munclinger Pavel
Published: October 2015

If offspring develop in adverse conditions, the maternal component of their phenotypic variation might increase due to the stronger dependence of offspring traits on parental investment. This should result in increased parental investment to individual offspring, as assumed by the model of optimal egg size. The opposite pattern, i.e., stronger dependence of offspring fitness on parental investment and consequently larger parental investment under good conditions is assumed by both the theory of differential allocation if attractive males provide material benefits, and reproductive compensation if they invest less into paternal care. Another influential idea is the Trivers‐Willard model, which assumes sex‐specific dependence of offspring fitness on parental investment. Here we tested these ideas by examining the effects of egg size on offspring fitness across many postnatal contexts in the Collared Flycatcher Ficedula albicollis. We employed a cross‐fostering design that generated variation in egg size within nests and used brood means of fledgling mass as a functional measure of the quality of rearing conditions. Effects of egg size on three offspring traits, including lifetime reproductive success of recruits, were more pronounced in low‐quality broods. These results support the assumption of the model of optimal egg size. Based on female preference for males providing material benefits, this pattern could support differential allocation, if attractive males invest less in paternal care, or reproductive compensation, if they invest more. By comparison, we did not find any evidence for sex specificity of fitness returns that might explain sex monomorphism of egg size in this species. The challenge for future studies will be the integration of components of parental investment and offspring fitness into their global measures and testing how the former affects the latter across gradients of postnatal conditions.
Multi‐scale environmental filters and niche partitioning govern the distributions of riparian vegetation guilds
Authors: Hough-Snee Nate , Laub Brian G. , Merritt David M. , Long A. Lexine , Nackley Lloyd L. , Roper Brett B. , Wheaton Joseph M.
Published: October 2015

Across landscapes, riparian plant communities assemble under varying levels of disturbance, environmental stress, and resource availability, leading to the development of distinct riparian life‐history guilds over evolutionary timescales. Identifying the environmental filters that exert selective pressures on specific riparian vegetation guilds is a critical step in setting baseline expectations for how riparian vegetation may respond to environmental conditions anticipated under future global change scenarios. In this study, we ask: (1) What riparian plant guilds exist across the interior Columbia and upper Missouri River basins? (2) What environmental filters shape riparian guild distributions? (3) How does resource partitioning among guilds influence guild distributions and co‐occurrence? Woody species composition was measured at 703 stream reaches and each species' morphological and functional attributes were extracted from a database in four categories: (1) life form, (2) persistence and growth, (3) reproduction, and (4) resource use. We clustered species into guilds by morphological characteristics and attributes related to environmental tolerances, modeling these guilds' distributions as a function of environmental filters—regional climate, watershed hydrogeomorphic characteristics, and stream channel form—and guild co‐existence. We identified five guilds: (1) a tall, deeply rooted, long‐lived, evergreen tree guild, (2) a xeric, disturbance tolerant shrub guild, (3) a hydrophytic, thicket‐forming shrub guild, (4) a low‐statured, shade‐tolerant, understory shrub guild, and (5) a flood tolerant, mesoriparian shrub guild. Guilds were most strongly discriminated by species' rooting depth, canopy height and potential to resprout and grow following biomass‐removing disturbance (e.g., flooding, fire). Hydro‐climatic variables, including precipitation, watershed area, water table depth, and channel form attributes reflective of hydrologic regime, were predictors of guilds whose life history strategies had affinity or aversion to flooding, drought, and fluvial disturbance. Biotic interactions excluded guilds with divergent life history strategies and/or allowed for the co‐occurrence of guilds that partition resources differently in the same environment. We conclude that the riparian guild framework provides insight into how disturbance and bioclimatic gradients shape riparian functional plant diversity across heterogeneous landscapes. Multiple environmental filters should be considered when the riparian response guild framework is to be used as a decision‐support tool framework across large spatial extents.
Cementing Quality Assurance: A Project Management Approach
Authors: Townsend S. C.
Published: October 2015

A cementing quality assurance process is presented which uses a project management approach to cementing operations from job design through execution to enhance the chances for successful zonal isolation on primary cement jobs. The process incorporates proven industry best practices for isolating potential flow zones during well construction. Although these practices are well documented in API Standard 65—Part 2 Second Edition 2010 recent studies of wells in the shale basins have shown that cementing failures are still occurring (Deane-Shinbrot et al. 2011; Bassett et al. 2012; Ingraffea 2013; Bassett et al. 2013; Davies et al. 2014).

The approach uses a four-step quality assurance process that includes the use of a cementing design checklist and the use of templates to document calculations related to the cementing operation. The process is as follows:

Establish clear objectives and identify constraints and remedies to the constraints. Optimize mud and spacer requirements and displacement rates. Other issues to be addressed are hole conditioning, possibility of pipe movement, optimization of casing centralization and length of shoe track. Optimize slurry requirements Implement field procedures using industry best practices

The paper also discusses the importance of conducting audits of quality control procedures used at facilities for laboratory testing, cement blending and pumping unit maintenance and provides some hypothetical examples showing how this could impact the success of the job.
A Wireline Logging Method for the Orientation of Fiber Optic and Control Lines in Highly Deviated or Horizontal Well Sections
Authors: Foster R. L. , Jacobson D.
Published: October 2015

The use of fiber-optic cable and control lines for instrumented well installations poses certain obstacles to companies wanting to safely design and execute perforating programs which do not damage the costly cable and instrument installations in highly deviated or horizontal wellbores (1). Tri-axial magnetic flux leakage logging tools enable the detection and orientation of fiber-optic cables and control lines so that perforating services may be planned and executed with confidence.

This method requires an understanding of the type and configuration of the hardware which was installed downhole to protect the fiber-optic or control line during installation and perforating. Surface test logging of the in-situ hardware ensures detection and orientation of the hardware installed in the well. Information derived from the surface test runs is used to detect, identify, and orient the hardware using well log data, and a report is created that defines the relative bearing of the fiber-optic or control line in the horizontal or highly deviated sections of the well. For instrumented well applications, hardware commonly known as blast protectors provide the key hardware features used for fiber-optic and control line protection during perforating operations.

This case study describes the surface testing method, logging and deployment options, analysis software, tool configuration, well log data, hardware examples and report.

NOVEL/Additional information:

Efficient procedure using high-resolution tri-axial magnetic flux leakage technology with post-processing analysis software designed to accurately and quickly provide orientation of fiber optic and control lines in wells of greater than 20° deviation.

Research on Low-voltage Series Arc Fault Detection Method Based on Least Squares Support Vector Machine
Authors: Yang Kai , Zhang Rencheng , Yang Jianhong , Chen Yongzhi , Chen Shouhong
Published: October 2015

Arc fault is one of the important reasons of electrical fires. In virtue of cross talk, randomness and weakness of
series arc faults in low-voltage circuits, very few of techniques have been well used to protect loads from series arc faults.
Thus, a novel detection method based on support vector machine is developed in this paper. If series arc fault occurs, high
frequency signal energy in circuit will increase a lot, and current cycle integrals are variable and erratic. However, high
frequency signal energy will be influenced by cross talk in a nearby branch circuit. Besides, current cycle integrals will also
vary while the working states of circuit changed. To better describe series arc faults, two characteristics include high
frequency signal energy and current integral difference are extracted as support vectors. Based on these support vectors,
least squares support vector machine is used to distinguish series arc faults from normal working states. The validity of
the developed method is verified via an arc fault experimental platform set up. The results show that series arc faults are
well detected based on the developed method.

Authors: Yuan Chuanlai , Kong Lingshuang , Hu Can , Zhou Weilong
Published: October 2015

In the countryside of China, the main power supply mode is 220V single-phase power, which affects the widely
application of three-phase agricultural appliances. What’s more, it means a block to the development of modern agriculture.
However, frequency converter technique research is focused on three-phase high power frequency conversion technology
at present, and there are very few achievements on the agricultural low power single-phrase frequency conversion
research. In this paper, considering the difficulty of widely application of agricultural low power three-phase AC motor
because it is not easy to obtain the three-phase power supply, a three-phase AC frequency conversion system under the
condition of agricultural 220V single-phase AC power is designed, which can achieve the stepless regulation of the voltage
amplitude and guarantee the widely use of the three-phase AC motor under the condition of agricultural 220V singlephase
AC power. The experimental results show that the system can output the controlled three-phase AC power when the
input is 220V single-phase AC power. And the rational design of the system hardware also provides the technical support
for the application of agricultural low power frequency conversion.

Published: October 2015

In order to study the effect of complementary pulp distribution, computational fluid dynamic (CFD) was used
to research on flow characteristic of hydraulic headbox based on complementary pulp distribution. Mass flow rate out of
mixing chamber and velocity distribution at slice of headbox were experimented. The results show that because of
simplified design, there was a little gradient of velocity and pressure which caused non uniform distribution of mass flow
rate out of branch pipes. Distribution of mass flow rate was ascended from inlet of header to outlet and the deviation was -
2.33% and 1.82%. There was intense interference between the jets of branch pipes in mixing chamber and the jets could
be sufficiently and complementarily mixed in rows and ranks. But the interference in the jets caused the accumulation of
the jets in the central section of mixing chamber and mass flow rate out of mixing chamber in the center was higher than
the two sides, and the maximum deviation was 0.538%. Distribution of velocity of pulp stock at slice of headbox was
very gentle and curve of distribution presented only slight fluctuation. The maximum deviation of velocity was only
0.175%. From the results of the experiment, the test values of mass flow rate out of mixing chamber were inosculated
with the calculated values and tested values of velocity at the slice of headbox were in accordance with the calculated
values. The results of experiment explained that the method of complementary pulp distribution was reasonable and could
obviously improve performance of pulp distribution of hydraulic headbox.

V-grooved steel plate 30mm in thickness has been taken into consideration to research on the distribution of
temperature field for the multi-pass welding of steel plate with intermediate thickness in the whole process of welding and
cooling. With the establishment of a reasonable three-dimensional solid model, the utility of ANSYS software for finite
element analysis, the usage of birth-death elements and the setting of normal Gauss heat source, steps have been
undertaken to achieve the goal that the process of multi-pass welding about steel plate in intermediate thickness is
simulated and the law of distribution about welding temperature field is obtained. The research results indicate the
following: the temperature in every point of base metal changes constantly when the steel plate 30mm in thickness is
being welded, the heat input position and position behind heat source are the integral parts which have the highest
temperature during the process that welded joints are welded, the temperature gradient in front of welding arc is pretty
large as well as that behind welding arc is relatively small. The calculation results are consistent with actual observations
providing exactly reliable references for stress field of the welding on steel plates.

This paper utilizes self-designed time-varying boundary sound emission test system for rock stratum fracture to
complete the sound emission orientation test upon the fracture of marble slab. A new method—image diagnosis and
orientation method is proposed to locate fracture section. Sound emission signal Y Position and Events-X position
distribution point diagram is utilized to determine the position of fracture surface; by analyzing the time-varying curve of
Counts, Energy and Hits of acoustic emission signal in the same stage, the occurrence moment of rock stratum fracture
section is confirmed and the development mechanism of fracture section is analyzed. Through study, it can be concluded
that located fracture section position is close to actual fracture position, indicating that sound emission image diagnosis
technique is characterized by high orientation precision, small error and good orientation effect; sound emission image
diagnosis orientation method has very excellent maneuverability and practicability.

Vision Technology
Authors: Mu Zhen-Hai
Published: October 2015

As is well known that sensing and measuring the weld pool surface is very important to design intelligent welding
machines which is able to imitate a skilled human welder who can choose suitable welding parameters. Therefore, in
this paper, we focused on the problem of weld pool surface 3D reconstruction, which is a key issue in intelligent welding
machines development. Firstly, the framework of the weld pool surface 3D reconstruction system is described. The weld
pool surface 3D reconstruction system uses a single camera stereo vision system to extract original data from weld pool,
and then the left and right images are collected. Afterward, we utilize Pixel difference square and matching algorithm and
Stereo matching algorithm to process images. Next, the 3D reconstruction of weld pool surface is constructed using the
point cloud data. Secondly, stereo matching based weld pool surface 3D reconstruction algorithm is illustrated. In this algorithm,
the matching cost function is computed through the Markov random field, and then the weighted matching cost
is calculated via the guided filter. Thirdly, to test the performance of our proposed algorithm, we develop an experimental
platform to measure weld pool width, length, convexity and the previous inputs based on a linear model predictive controller.
Experimental results demonstrate that the proposed 3D reconstruction algorithm of weld pool surface can achieve
high quality under both current disturbance and speed disturbance.

This paper proposed a three-dimensional model of treadmill, structural diagram of mechanical transmission,
structural optimization model and kinematic analysis model, deriving the values of connecting rods as 0.425 m, 1.673 m and
0.662 m by solving the optimization model. It further conducts a kinematic analysis on treadmill using this set of parameters
and kinematic simulation software “Motion”, providing simulation curves of angular displacement, angular velocity and
angular acceleration of the main moving parts such as the connecting rods, pedals and handrail handles. The simulation
curves indicate that when the rotation speed of the wheels is 10 r/min, the connecting rods, pedals and handrail handles move
smoothly and change almost sinusoidally; the displacement of handles ranges in-700∼200 mm, the speed ranges in-400∼400
mm/s, the acceleration ranges in -400∼500 mm/s2, the angular change of pedals is -5°∼30°, the amplitude variation of angular
velocity is <25°/s and the amplitude variation of angular acceleration is <28°/s2. The above mentioned calculated prospects
of the treadmill provide some reference for carrying out a quick optimization design of the treadmill.

Authors: Yao Jun , Tang Yu , Zhu Zhencai
Published: October 2015

During the operation of a crawler crane driven by double winches, it is important to make the two winches
actuate synchronously so that the hook is in a horizontal state to prevent accidents. In this paper, a novel synchronization
control strategy for crawler crane driven by double winches using hook angle feedback information is proposed. The hook
angle proportional to the length error of ropes is measured by a wireless angle sensor firstly and is then employed as a
feedback control signal. To further improve the synchronization performance, cross-coupled control scheme together with
the variable speed PID control is utilized on the basis of the collected hook angle signal. Simulations and experiments are
then conducted and the results demonstrate that the proposed control scheme can obtain a better synchronization
performance than the conventional control strategy using encoders and the inclination of the hook is greatly reduced to a
limited small range.

Ankylosing spondylitis is a spondyloarthropathy affecting the sacro-iliac joints with subsequent progression to the spine and the hip joints. The hip joints are affected by synovitis, enthesial inflammation, involvement of medullary bone, progressive degeneration and secondary osteoarthritis. Clinical presentation is usually in the form of pain and stiffness progressing to disabling fixed flexion contractures and in some instances, complete ankylosis. Hip arthroplasty should be considered for hip pain, postural and functional disability, or pain in adjacent joints due to hip stiffness. We conducted a literature review to determine peri-operative considerations and outcome in ankylosing spondylitis patients undergoing hip arthroplasty. In this review, we have discussed pre-operative surgical planning, thromboprophylaxis, anaesthetic considerations and heterotopic ossification. Outcomes of arthroplasty include range of movement, pain relief, survivorship and complications.
