Design and analysis of the flange-bolted joint with respect to required tightness and strength
Authors: Jaszak Przemysław , Adamek Konrad
Published: August 2019

The paper presents the method of design and strength analysis of the flange-gasketed-bolted joint. In the first part, analytical calculations were carried out. Their purpose was to determine the assembly torque of nuts to achieve the desired tightness. The flanged joint designated as DN100 PN40 with two different gaskets was taken into consideration. The analytical calculations were performed in accordance with the algorithm included in PN EN 1591-1. In the further step, the numerical calculations were carried out to support the analytical results. The outcome of these calculations were maps of the contact stress distribution on the gasket surface, estimation of safety factors of individual joint elements as well as determination of the flange rotation. Data from the numerical calculations were compared with the analytical results, which confirmed their satisfactory compliance. In the last stage, the experimental tests of the joint were carried out. The main results of the test were the measured values of the leakage level, tightening force of the bolt and estimated safety factors. An indirect result of the experimental measurements were maps of the stress distribution on the contact surface of the gasket, which were determined by means of the measuring film. Ultimately, based on the experimental results, it was found that the proposed analytical method of calculation and simulation of the joint by means of the finite element method was a very good tool for the design of the joint at the required tightness level.
New speakers, new language: on being a legitimate speaker of a minority language in Provence
Authors: Costa James
Published: August 2019

This article looks at the “new speaker” concept and the questions it raises in terms of legitimacy from the point of view of several types of social actors, namely language advocates, academics and school pupils (that is to say, “new speakers” themselves). The aim of this article is to show that this notion is not a purely descriptive one, but also carries a strong prescriptive loading – which in turns requires that minority language learners negotiate their participation in linguistic markets. Based on fieldwork in Provence, I look at how “new speakers” are often construed as speakers of “new languages”, “standard” or “artificial” languages that tend to index youth, urbanity, modernity and middle class membership – all qualities which may be seen as undesirable in parts of minority language movements. I then turn to pupils of an Occitan bilingual primary school in Provence and analyse how they reframe the new speaker debate in order for themselves to fit in the broader picture of Occitan speakers. All the viewpoints I analyse tend to emphasise the weight that the traditional, monolingual speaker still holds among speakers of minority languages in southern France.
Linguistic mudes: how to become a new speaker in Catalonia
Authors: Pujolar Joan , Puigdevall Maite
Published: August 2019

New speakers of Catalan have come to represent, from a demolinguistic perspective, a substantial part of the community of speakers. Of those who presently speak Catalan as an “habitual language”, 41.6 percent are native speakers of Spanish. In this article, we shall follow up the various ways in which native Castilian speakers incorporate Catalan into their lives. This happens, as we will show, in specific biographical junctures that we call mudes, a Catalan term referring to (often reversible) variations in social performance. Our analysis is based on a qualitative study that included 24 interviews and 15 focus groups covering a total of 105 people of different sexes and linguistic, educational, social and residential backgrounds. We shall give a general overview of these mudes as we typified them: when subjects entered primary school, secondary school, the university, the job market, when creating a new family and when they had children (if they did). The study of linguistic mudes provides, in our view, a new and productive perspective on how people develop their linguistic repertoire, their attachment to specific languages and the significance of these aspects for social identity. It facilitates a processual, time-sensitive analysis that allows to contextualise and critique ethnonationalist discourses that have often saturated our understanding of language use.
The pro-algesic effect of γ-aminobutyric acid (GABA) injection into the masseter muscle of healthy men and women
Authors: Meijs Suzan , Liao Shaojun , Arendt-Nielsen Lars , Wang Kelun , Cairns Brian E.
Published: August 2019

Background and aims

Preclinical studies have reported that activation of peripheral γ-aminobutyric acid A (GABAA) receptors may result in analgesia. The current study was conducted in young healthy men (n = 30) and women (n = 28) to determine whether injections of GABA into the masseter muscle reduce pain in a sex-related manner.

Methods

The effect of injection of GABA alone, or in combination with the non-inflammatory algogen glutamate, was assessed in two separate studies. Lorazepam, a positive allosteric modulator of the GABAA-receptor, was co-injected with GABA in both studies to explore the role of this receptor in muscle pain responses of healthy human volunteers. Masticatory muscle mechanical pain intensity was recorded on an electronic visual analogue scale (VAS) while muscle pain sensitivity was assessed by determining the pressure pain threshold (PPT), tolerance and maximal jaw opening (MJO) of the subjects prior to, and again after the various intramuscular injections.

Results

Intramuscular injection of GABA alone was reported to be significantly more painful, in a concentration related manner, than saline control injections, and this pain was further increased by co-injection of lorazepam with GABA. Co-injection of GABA with glutamate was found to significantly increase glutamate-evoked masseter muscle pain in men, but not in women. There was no effect of injections of either GABA alone, or GABA with glutamate, on PPT, tolerance or maximum jaw opening.

Conclusions

Injection of GABA into the human masseter muscle appears to excite nociceptors to produce muscle pain without a longer term effect on mechanical pain sensitivity in the muscle. The findings suggest that GABA-mediated pain in humans is produced through peripheral GABAA receptor activation. The mechanism underlying the sex-related difference in the effect of GABA on glutamate-evoked muscle pain was speculated to be due to a methodological artifact.

Implications

This study was designed to detect analgesic rather than algesic effects of peripherally administered GABA, and as a result, the concentration of glutamate chosen for injection was close to the maximal pain response for healthy women, based on previously determined pain-concentration response relationships for glutamate. This may explain the finding of greater pain in men than women, when GABA and glutamate were co-injected. Overall, the findings suggest that activation of peripheral GABAA receptors in human masticatory muscle produces pain, possibly due to depolarization of the masticatory muscle afferent fibers.

Published: August 2019

OBJECTIVES:

To determine the association between parenteral antibiotic duration and outcomes in infants ≤60 days old with bacteremic urinary tract infection (UTI).

METHODS:

This multicenter retrospective cohort study included infants ≤60 days old who had concomitant growth of a pathogen in blood and urine cultures at 11 children’s hospitals between 2011 and 2016. Short-course parenteral antibiotic duration was defined as ≤7 days, and long-course parenteral antibiotic duration was defined as >7 days. Propensity scores, calculated using patient characteristics, were used to determine the likelihood of receiving long-course parenteral antibiotics. We conducted inverse probability weighting to achieve covariate balance and applied marginal structural models to the weighted population to examine the association between parenteral antibiotic duration and outcomes (30-day UTI recurrence, 30-day all-cause reutilization, and length of stay).

RESULTS:

Among 115 infants with bacteremic UTI, 58 (50%) infants received short-course parenteral antibiotics. Infants who received long-course parenteral antibiotics were more likely to be ill appearing and have growth of a non–Escherichia coli organism. There was no difference in adjusted 30-day UTI recurrence between the long- and short-course groups (adjusted risk difference: 3%; 95% confidence interval: −5.8 to 12.7) or 30-day all-cause reutilization (risk difference: 3%; 95% confidence interval: −14.5 to 20.6).

CONCLUSIONS:

Young infants with bacteremic UTI who received ≤7 days of parenteral antibiotics did not have more frequent recurrent UTIs or hospital reutilization compared with infants who received long-course therapy. Short-course parenteral therapy with early conversion to oral antibiotics may be considered in this population.
Moulds for large daggers. Unique finds from the Bronze Age Hatvan-Strázsa-hegy tell
Authors: Tarbay János Gábor
Published: August 2019

The present study discusses five Bronze Age sandstone casting moulds from the Hatvan-Strázsa-hegy tell (Hungary, Heves County), which have been acquired by the Ministry of Defence Institute and Museum of Military History in the 1990s. One of the moulds is a semi-finished product, showing a negative of a dagger hilt pommel. The other four moulds were suitable to cast large triangular-shaped dagger blades and they can be arranged into two pairs, based on their dimensions and the outlines of their negatives. According to macroscopic observations, these finds have been used for a period of time, proving that advanced metallurgy was present on the Strázsa-hegy site during the Rei. Br. A. Besides they provide a chance for an evaluation of these significant objects that do not abound in parallels. The main goal of this paper is to discuss and reconstruct the life-cycle of daggers, based on macroscopic data obtained from the moulds and their parallel finds.

Published: August 2019

Wali asuh dalam pesantren berperan dalam menanggulangi penurunan efektifitas kegiatan santri yang diakibatkan semakin banyaknya jumlah peminat pesantren modern dan semi modern dewasa ini. Intisari dari adanya wali asuh adalah sebuah ide pembaruan di pesantren sebagai upaya meningkatkan efektifitas kegiatan dan memudahkan pemantauan aspek psikis santri secara perorangan. Penelitian ini menggunakan pendekatan studi kasus di pesantren Nurul Jadid yang berlokasi di Kabupaten Probolinggo. Hasil penelitian menunjukkan beberapa strategi yang harus dilakukan wali asuh dalam perannya sebagai pengganti orang tua santri. Pertama, wali asuh melakukan pendekatan awal dengan menjadi pendengar yang baik santri asuh untuk menghimpun informasi tentang dunia kehidupannya. Kedua, pemeran wali asuh harus berbeda dengan pemeran pengurus harian untuk memberikan ruang pendekatan pribadi, bukan kolektif. Ketiga, wali asuh berperan pula sebagai motivator, konselor dan pengganti orang tua bagi santri asuh.

Unsupervised Cross-Spectral Stereo Matching by Learning to Synthesize
Authors: Liang Mingyang , Guo Xiaoyang , Li Hongsheng , Wang Xiaogang , Song You
Published: August 2019

Unsupervised cross-spectral stereo matching aims at recovering disparity given cross-spectral image pairs without any depth or disparity supervision. The estimated depth provides additional information complementary to original images, which can be helpful for other vision tasks such as tracking, recognition and detection. However, there are large appearance variations between images from different spectral bands, which is a challenge for cross-spectral stereo matching. Existing deep unsupervised stereo matching methods are sensitive to the appearance variations and do not perform well on cross-spectral data. We propose a novel unsupervised crossspectral stereo matching framework based on image-to-image translation. First, a style adaptation network transforms images across different spectral bands by cycle consistency and adversarial learning, during which appearance variations are minimized. Then, a stereo matching network is trained with image pairs from the same spectra using view reconstruction loss. At last, the estimated disparity is utilized to supervise the spectral translation network in an end-to-end way. Moreover, a novel style adaptation network F-cycleGAN is proposed to improve the robustness of spectral translation. Our method can tackle appearance variations and enhance the robustness of unsupervised cross-spectral stereo matching. Experimental results show that our method achieves good performance without using depth supervision or explicit semantic information.
Scene Text Recognition from Two-Dimensional Perspective
Authors: Liao Minghui , Zhang Jian , Wan Zhaoyi , Xie Fengming , Liang Jiajun , Lyu Pengyuan , Yao Cong , Bai Xiang
Published: August 2019

Inspired by speech recognition, recent state-of-the-art algorithms mostly consider scene text recognition as a sequence prediction problem. Though achieving excellent performance, these methods usually neglect an important fact that text in images are actually distributed in two-dimensional space. It is a nature quite different from that of speech, which is essentially a one-dimensional signal. In principle, directly compressing features of text into a one-dimensional form may lose useful information and introduce extra noise. In this paper, we approach scene text recognition from a two-dimensional perspective. A simple yet effective model, called Character Attention Fully Convolutional Network (CA-FCN), is devised for recognizing the text of arbitrary shapes. Scene text recognition is realized with a semantic segmentation network, where an attention mechanism for characters is adopted. Combined with a word formation module, CA-FCN can simultaneously recognize the script and predict the position of each character. Experiments demonstrate that the proposed algorithm outperforms previous methods on both regular and irregular text datasets. Moreover, it is proven to be more robust to imprecise localizations in the text detection phase, which are very common in practice.
Spatial and Temporal Mutual Promotion for Video-Based Person Re-Identification
Authors: Liu Yiheng , Yuan Zhenxun , Zhou Wengang , Li Houqiang
Published: August 2019

Video-based person re-identification is a crucial task of matching video sequences of a person across multiple camera views. Generally, features directly extracted from a single frame suffer from occlusion, blur, illumination and posture changes. This leads to false activation or missing activation in some regions, which corrupts the appearance and motion representation. How to explore the abundant spatial-temporal information in video sequences is the key to solve this problem. To this end, we propose a Refining Recurrent Unit (RRU) that recovers the missing parts and suppresses noisy parts of the current frame’s features by referring historical frames. With RRU, the quality of each frame’s appearance representation is improved. Then we use the Spatial-Temporal clues Integration Module (STIM) to mine the spatial-temporal information from those upgraded features. Meanwhile, the multilevel training objective is used to enhance the capability of RRU and STIM. Through the cooperation of those modules, the spatial and temporal features mutually promote each other and the final spatial-temporal feature representation is more discriminative and robust. Extensive experiments are conducted on three challenging datasets, i.e., iLIDS-VID, PRID-2011 and MARS. The experimental results demonstrate that our approach outperforms existing state-of-the-art methods of video-based person re-identification on iLIDS-VID and MARS and achieves favorable results on PRID-2011.
Almost Unsupervised Learning for Dense Crowd Counting

Published: August 2019

We present an unsupervised learning method for dense crowd count estimation. Marred by large variability in appearance of people and extreme overlap in crowds, enumerating people proves to be a difficult task even for humans. This implies creating large-scale annotated crowd data is expensive and directly takes a toll on the performance of existing CNN based counting models on account of small datasets. Motivated by these challenges, we develop Grid Winner-Take-All (GWTA) autoencoder to learn several layers of useful filters from unlabeled crowd images. Our GWTA approach divides a convolution layer spatially into a grid of cells. Within each cell, only the maximally activated neuron is allowed to update the filter. Almost 99.9% of the parameters of the proposed model are trained without any labeled data while the rest 0.1% are tuned with supervision. The model achieves superior results compared to other unsupervised methods and stays reasonably close to the accuracy of supervised baseline. Furthermore, we present comparisons and analyses regarding the quality of learned features across various models.

Discusión: Se discute sobre la importancia de generar un protocolo de valoración de la ToM haciendo una validación estadística de estos instrumentos.
Variación anatómica de la madera de Avicennia germinans en la Laguna de la Mancha, Veracruz, México
Authors: Yáñez Espinosa Laura , Angeles Guillermo , López Portillo Jorge , Barrales Saamantha
Published: August 2019

Avicennia germinans es una especie de mangle que presenta marcada tolerancia a la salinidad, pero sólo se habían observado tendencias a aumentar el tamaño de los caracteres del xilema secundario a bajas concentraciones de salinidad. En la Laguna de la Mancha, Veracruz, esta especie se distribuye en un gradiente de salinidad amplio, lo que hace interesante analizar la variación de sus caracteres anatómicos con respecto a la salinidad. Los resultados sugieren que las diferencias entre sitios para los caracteres a) grosor tangencial de pared de vaso, b) frecuencia de vasos y c) diámetro tangencial del lumen de fibra, se pueden atribuir al efecto del ambiente. El incremento de los tres caracteres anatómicos al aumentar la salinidad y el período de inundación implica una compensación entre eficiencia hidráulica y estabilidad mecánica del xilema. Esto sugiere que el calentamiento global puede afectar a A. germinans al aumentar la salinidad debido a la elevación del nivel del mar, afectando su eficiencia en la conductividad hidráulica, reduciendo su crecimiento en altura y en el área foliar.

Published: August 2019

Se caracterizó la heterogeneidad biótica y abiótica tanto espacial como temporal en dos zonas del matorral xerófilo de la Reserva Ecológica del Pedregal de San Ángel(REPSA). Se identificaron nueve grupos florísticos, los cuales presentaron una distribución diferencial de las especies vegetales presentes en la zona. Cada uno de los grupos fue nombrado respecto a las especies indicadoras, las cuáles fueron consideradas como determinantes de la fisonomía de la comunidad. Utilizando los análisis multivariados(TWINSPAN y CANOCO) se observó que la composición de especies de los grupos se modifica espacial y temporalmente. Este estudio sugiere que la variación de algunos factores abióticos como la profundidad del suelo y la pendiente influye de diferente manera en la heterogeneidad del sistema. La heterogeneidad temporal fue evidente al existir una diferente composición florística en la zona a lo largo de la temporada de lluvias y la temporada de secas.

Developing Students’ Writing through Scaffolding Techniques in a Workshop Forum
Authors: Sidky Gihan
Published: August 2019

This study aimed at enhancing students’ essay writing skills at the secondary stage through scaffolding techniques in a workshop forum. The participants of the study were 40 students at the first secondary stage in a governmental language school. Qualitative methods were used in data analysis; a sample of students’ writings was analyzed in light of the academic writing assessment criteria (Rose et al. 2008).  A pre-posttest was administered to highlight progress in students’ writing in the three genres. Scaffolding techniques proved to be effective in improving students’ writing skills, specifically in the selected writing genres the study focused on which was evident in their second and third drafts. Interviews with high school teachers of English emphasized students need for innovative scaffolding techniques to help them develop as efficient writers. The workshop forum encouraged students to work together as one team and to express their ideas fluently to excel in their writing assignments. Having an authentic reason for writing motivated them to do research and to refine their writing to be good enough to share with others.
Reassessing the Methods of Foreignizing and Domesticating Translation
Authors: Zhao Xinkan
Published: August 2019

This paper clarifies the frequently used concepts of foreignizing and domesticating translation to the extent that they can be meaningfully evaluated. As it turns out, foreignizing translation is best understood as including more than one method, with each having its own evaluative profile, and domesticating translation should be cleared of confusion with other methods that have historically brought it a bad name. Based on detailed evaluations, the paper briefly proposes collaboration as the proper way forward and also shows how the ambitious strategy of foreignizing, which might be named after the German Romantic scholar Friedrich Schleiermacher, is special and what reasons there are not to accept it. Before concluding, the paper addresses issues most relevant to translating philosophical texts, where terminologies have often already been foreignized through stipulation.
Reading Strategies and Reading Fluency: A Case Study of Reading in First or Second Language
Authors: Barzegar Najmeh , Fazilatfar Ali. M.
Published: August 2019

The ability to read in second or foreign language (L2/FL) is a vital skill for academic and autonomous language learning. This study investigates the reading performance of two TEFL students from different language backgrounds on two English texts and their equivalent Persian translations comparing their reading rate and comprehension in L1 and L2. A combination of think-aloud protocol, interview and observation methods was used in order to figure out the reading strategies used by each participant in the process of reading and comprehending each text. First, participants were asked to model the steps of their thinking when reading the same text and to discuss what strategies and process they went through while interacting with the passage. Then, they were asked to respond some questions at the end of each reading passage. Last, an interview about their reading experiences and strategies is conducted. Findings of collected data from multiple sources were examined in the sense that the overall extracted themes were triangulated. The data were analyzed based on the Uso-Juan, Esther and Alicia Martinez-Flor (2006) framework for key reading strategies. The result showed that there is a positive relationship between reading fluency and reading comprehension. The most effective strategies employed by each participant were also reported. Through critically and analytically reflecting on differences between L1 and L2 reading, language learners can learn how to read so as to get the most out of their academic materials.

Authors: Haque S. M. Fazlul , Salem Norah Mofareh Al
Published: August 2019

This study investigates the impact of Social Media (SM) on students’ attitudes towards the process of learning EFL from the learners’ perspectives. The hypothesised model is developed through social learning theory proposed by Vygotsky (1978). The sample population of this research consists of 228 undergraduate students (153 females and 75 males) enrolled in the Department of English Language at Najran University in Saudi Arabia. The instruments used to gather data from the participants included a self-designed online electronic survey and semi-structured interviews. Results show that Najran University students believe that SM positively improves their understanding of English. Moreover, students agree that SM is a good platform to improve their proficiency in English. They also reported that SM changes their attitudes towards English positively. The findings also indicate that SM is a good platform for students as it provides opportunities for learners to study foreign languages. As SM tools grow and new generations get attached to them, additional studies on the adoption of these tools must be conducted to support students’ learning.

This
study aims to describe experiences of gender essentialist attitudes in engineering
faculties in Turkey. It is a phenomenological research based on semi-structured
interviews made with 9 women and 6 male academics in 2017. A mix of a
snowballing sampling and convenience sampling were used to reach the research
subjects. Descriptive analysis was made to interpret the data. The results
indicate that women academics suffer from essentialist views in relation to
general aspects of womanhood as well as in relation to specific aspects such as
motherhood, bodily strength, authority, sociality and emotionality. The results
suggest that male dominated universities would be well advised to begin by
looking for essentialist presuppositions about gender among the members of
their staff.

A Study of the Stress-Strain State of the Planetary Carrier Cheek

Planetary gears are commonly used in drive technology due to their high load capacity and good weight and size parameters. Among planetary gears, multi-satellite structures with a minimum number of excessive links are most widely used. They have a close to uniform distribution of the load in the engaged gears, which has a positive effect on the strength and bearing capacity of the drive. Such designs include planetary gears, the satellites of which are mounted on spherical bearings, and one of the main links (most often the sun gear) is self-aligning. This provides a theoretically uniform distribution of the load in the engaged gears when the mechanism has three satellites. However, high-loaded drives often use designs with a large number of satellites where the load is distributed unevenly due to gear manufacturing errors. The deformability of individual transmission elements has a significant positive effect on the distribution of the load in the gears, thus compensating for the manufacturing errors. In view of this, the authors propose a multi-satellite planetary gear with a carrier made with grooves in the cheeks, which reduces their rigidity and provides, with a rational choice of the parameters of the mechanism, an increase in the mechanism’s bearing capacity. When determining the carrier cheek’s compliance, two schemes of loading in the coupling zone with the axis of the satellite (uniform and nonuniform) are considered. The solution is obtained using Mohr’s integrals. A numerical analysis of the stressed-strain state of the carrier cheek performed using the finite element method in the SolidWorks environment showed that the results of the analysis were close to the theoretical ones. They corresponded to a uniform load distribution in the coupling zone of the satellite axis and the carrier cheek. The obtained dependences can be used in the design of a mechanical drive to determine the coefficients of the uneven load distribution over the planetary gear satellites and over the individual crowns of the satellite.
