Evidencias de (inter)subjetividad en el discurso institucional-estatal : la contribución del análisis del discurso para el pensamiento crítico
Authors: Marchese Mariana Carolina 
Published: March 2019

Desde el marco teórico del Análisis Crítico del Discurso, a partir de una metodologia cualitativa y a través del Análisis del Discurso como método, este trabajo presenta evidencias lingüísticas de que aquellos textos que se suponen objetivos son construidos (inter)subjetivamente. Los resultados del análisis manifiestan dos series de recursos que actúan en forma conjunta. Una serie de recursos que apuntan a borrar al emisor de la superficie textual y otra serie, que actúa en forma paralela a la anterior, formada por recursos evaluativos-subjetivos. Así, el Análisis del Discurso permite el pasaje a la reflexión crítica sobre el complejo rol del discurso dentro de los fenómenos sociales.
A experiência discursiva e a singularidade: levantamento de questões no campo da aquisição de linguagem
Authors: Carvalho Glória , Rozental Eva 
Published: March 2019

The present paper is an attempt to discuss the relationship between shared discursive experience and the child’s singular speech, at an early stage of his/her linguistic course. The infant’s unusual utterances were selected and taken as units of analysis, that is, the types of utterances which are unfamiliar to the adult, thus highlighting the singularity aspect. By confronting verbal data of a diad (mother-child), the relevance of considering the discursive experience background between the two speakers stood out within the study of the changes occurring in the subject, from his/her condition of non-speaker into a new condition of speaker. Nevertheless, there is an indication that there would be a language movement towards two poles: metaphorical and metonymical. These would act on such discursive experience, making it return, in the child’s utterances as a different, singular structure.

Heat-Stable Carbetocin Could Replace Oxytocin To Prevent Postpartum Haemorrhage Following Vaginal Delivery
Authors: Thapa Bikram 
Published: March 2019

Postpartum haemorrhage (PPH) is the most common type of obstetric haemorrhage and accounts for 35% of all maternal deaths. World Health Organisation (WHO) defines PPH as: blood loss of 500 mL or more within 24 hours following vaginal delivery. PPH is the leading cause of maternal mortality in low-income countries, and the primary cause of nearly one quarter of all maternal deaths globally. Uterine atony is the most common cause of PPH accounting for more than 80% of causes. Thus, to prevent PPH, WHO has recommended active management of third stage of labor. All women giving birth should be offered uterotonics during the third stage of labor (as a part of third stage management) for the prevention of PPH; oxytocin (IM/IV, 10 IU) is recommended as the uterotonic drug of choice.

Conclusion: Heat stable carbetocin can be a breakthrough drug for overcoming heat degradation of oxytocin. Cold chain for storage or transportation of uterotonic drug is thus now not an issue. This single advantage can remarkably reduce the morbidity and mortality in low-income countries due to PPH as this drug can be made available even in most remote part of the country. Heat-stable carbetocin was studied aiming the developing countries. We can hope to see this drug in the new update in WHO recommendation for prevention of postpartum hemorrhage; that undoubtedly would be a very remarkable change, especially for resource limited countries like ours.

Published: March 2019

Introduction: Sustainable development goal 3 targets at ensuring healthy lives and promoting well-being for all at all ages. One of the component for achievement of this goal is improvement of maternal and child health; the indicators of which is perinatal mortality rate. The aim of this study was to evaluate the cause of perinatal death in a tertiary care medical centre, which may help to reduce the incidence of perinatal death and improve the quality of care.
Methods: A prospective study was done over a period of one year from April 2016 to March 2017. Causes of perinatal deaths based on PSANZ classification were recorded along with patients demographics and also avoidable factors were evaluated.
Results: Out of total 1275 deliveries, there were 21 perinatal deaths including three intrauterine foetal deaths, one still birth and seven early neonatal deaths. The perinatal mortality rate was 16.27 per 1000 birth. Majority of perinatal deaths (19%) occurred due to congenital anomalies followed by (14%) hypertensive disorder in pregnancy, intrapartum hypoxia (14%), unexplained causes (14%), 9.5% cord prolapse, antepartum haemorrhage (9.5%), 5% due to intrauterine growth restriction, gestational diabetes mellitus or preterm labour. Most of the mothers whose baby had perinatal deaths had ANC outside. Most of the deaths occurred in between gestational age of 37 to 41 weeks. Perinatal mortality was more in multigravida. Delay to seek health care and inadequate antenatal checkups were the most common avoidable factors.
Conclusions: Congenital anomalies and hypertensive disorders during pregnancy were the most common causes of perinatal death. Delay in health seeking behaviour was the most common avoidable factors for perinatal death. We recommend early identification of high risk pregnancy through proper antenatal screening, educating pregnant women to identify danger signs of pregnancy, creating public awareness about importance of antenatal checkups, vigilant labour monitoring for foetal distress, to reduce some categories of deaths.

Published: March 2019

Background: Globally, more than half of all TB cases are not detected. If they are not diagnosed and get treatment infection transmission may continue and patients suffer and may eventually die. Pulmonary TB either smear positive or negative is normally diagnosed by Ziehl-Neelsen stained sputum smear examination microscopy. Since the culture is the gold standard, evaluation of smear negative TB cases by this method is likely to detect more cases.
Objectives: The objective of this study is to find out culture positivity among smear negative patients.
Methods: All the three sputum samples reported negative by Ziehl-Neelsen microscopy from a total of 138 new TB suspected cases more than 15 years of age at NTC Laboratory. Nepal were cultured on Lowenstein-Jensen media. Tubes showing sufficient growth (culture positive) were recorded and all the culture positive results were informed to NTC. The culture positive samples were processed for DST on first line drugs using proportion method.
Results: The culture positivity rate was 5.1% (7 of 138 cases) All the positive cultures were processed for DST on first line anti-TB drugs and none showed resistance of the total 138 suspected Tuberculosis patients, 94 (68.1%) were males and 44 were females (31.9%) with male: female ratio 1:047. The mean age of the total patients were 30.69. Nearly 42% of them belonged to 31-50 years. Mean age of the male patients was significantly higher than total of the female (p<.001).
Conclusions: Seven smear negative cases among the total of 138 suspected TB patients attending NTC were culture positive. Similar study has to be done in other parts of the country.
StressLifetc – NDT-related assessment of the fatigue life of metallic materials
Authors: Starke Peter 
Published: March 2019

Abstract
Weight-optimized component design as well as a reliable estimation of the lifetime of metallic materials and components requires a comprehensive understanding of fatigue processes and a systematic investigation of the underlying fatigue behavior. Therefore, nondestructive testing methods, digitalization of measurement techniques as well as signal processing can be combined with a short-term procedure in order to acquire potentially more information about fatigue processes, while experimental effort and costs are reduced significantly. This leads not only to considerable advantages over conventional methods for determining S-N curves, but also over established short-term procedures, due to the possibility of applying this information from just a few specimens to attain fatigue life calculations. The StressLifetc approach is a new short-term calculation method which considers the nonlinear relation between the elastic, elastic-plastic and plastic portion of the material response in the deformation process. Within the scope of the present work, the change in temperature of SAE 1045 (C45E) specimens was measured during fatigue tests via an infrared camera in order to feed the thermal response back into the new StressLifetc approach for a reliable fatigue life calculation.
Comparative study on fatigue behavior between unbonded prestressed and ordinary reinforced reactive powder concrete beams
Authors: Luo Xuguo , Tan Zhenglong , Chen Y. Frank , Wang Yixiang 
Published: March 2019

Abstract
Two types of reactive powder concrete beams, one with normal mild steel and another with unbonded prestressing tendons, were studied experimentally. Specifically, static load and constant amplitude fatigue tests were performed. The beam cracks, midspan deflections, and variations of extreme concrete and steel strains with fatigue loading cycles were compared. The fatigue test results show that fatigue life is more than 2 million cycles for both types of RPC beams within the usual low fatigue stress range (98 % probability of appearance). The crack width, maximum compressive strain, midspan deflection, and maximum tensile strain are 0.08 mm, 814 μξ, 7.6 mm, and 484 μξ, respectively for unbonded prestressed reactive powder concrete beams. They are 0.12 mm, 1147 μξ, 10.3 mm, and 1226 μξ, respectively for ordinary reinforced reactive powder concrete beams. All of these values obtained from the fatigue test are significantly below the corresponding failure values under the static test. The study results show that an unbonded prestressed reactive powder concrete beam has better fatigue performance than an ordinary reinforced reactive powder concrete beam.
Quantitative analysis of metal fiber morphology by level set image segmentation algorithms

Published: March 2019

Abstract
Due to their advantages of high porosity, large specific surface area, and abundant surface topography, porous fiber-sintered plates are widely used in microreactors. The fiber surface in the cutting process generates a rich micro-surface morphology which can effectively improve the catalyst load and promote reaction efficiency. There is currently a lack of quantitative analysis of the microchannel surface topography features. In this study, a new image segmentation technique based on level set algorithms was developed to study the microscopic features of the metal fibers processed under different processing parameters, allowing for the establishment of a matching relationship between the microscopic roughness of the fiber surface and the equivalent diameter of the fibers. The experimental results show that the surface topography characteristic coefficient (STCC) was approximately inversely proportional to the cutting speed (r × min−1), which was approximately proportional to the feed (mm × r−1). The cutting depth (mm) effect on the STCC value of the fibers was not obvious. At low speed, with a cutting speed n = 20 r × min−1, feed rate f = 0.08 mm × r−1, and cutting depth ap = 0.11 mm, the STCC of the metal fiber reached a maximum value of 115.927. At high speed, with a cutting speed of n = 400 r × min−1, feed rate f = 0.06 mm × r−1, and cutting depth ap = 0.17 mm, the metal fiber STCC reached a maximum of 128.605. The parameters corresponding to the maximum STCC value can be used as the optimal turning parameters of metal fiber material for making a porous fiber microchannel reactor.

Published: March 2019

Abstract
Nanocomposites have attracted much attention from scientific and industrial areas in recent decades because of their mechanical, physical, thermal and barrier properties and unique design possibilities. These materials have been commercially used in the automotive, electronic, biomedical, packaging etc. industries and their usage areas have been increasing day by day. In this study, nanocomposite adhesives were produced by adding nano graphene and multi-walled carbon nanotube (MWCNT) particles to a single component epoxy adhesive at the ratios of 0.1, 0.2, 0.3, 0.4, 0.5, 0.7, 1, 3 and 5 wt.-%. Then, these nanocomposite adhesives were used to prepare single-lap joints. Shear tests were performed to specify their adhesive shear strengths and joint tensile strengths. It was observed that mechanical strength increased to the reinforcement amount of 0.5 wt.-%. After that, the strength values decreased due to a tendency towards agglomeration, viscosity increment and due to a difficulty in homogeneously applying the adhesive. Furthermore, it was found that nano graphene reinforcement improved the mechanical strength of the epoxy-based adhesive slightly more than MWCNT reinforcement.
Experimental study on gas emission from coal mass with a rich microstructure
Authors: Zhang Huan , Zhao Hongbao , Wang Tao , Huang Yifan 
Published: March 2019

Abstract
Through a coal mass sample with a rich microstructure and a self-designed experiment using lump coal to determine the characteristics of gas emission, this paper analyzes gas emission in a coal mass with rich microstructure. The results show: The differences between raw coal and a briquette are mainly found in the scale and number of their microstructures. Nevertheless, the two samples share a high degree of similarity. The gas emission speed of a coal particle is higher than that of coal mass with a rich microstructure. The decay rate of gas emission speed also is confirmed as the same process. It takes longer for coal mass with a rich microstructure to reach the limit of its gas emission volume than for coal particles. Gas emission in a coal mass is a continuous process of gas desorption, migration and seepage. During the process, the coal mass reacts in four possible ways: coal mass immediately participating in gas emission, gradually participating in gas emission, providing a gas source for gas emission and as a non-affected coal mass. The relation between the gas emission speed of the coal mass with a rich microstructure and test time shows a monotone decrease in the power function, and the relation between the cumulative volume of the gas emission and the test time reveals a monotonically increasing logarithmic function. The gas emission for coal mass with a rich microstructure can be well expressed by modified logarithmics.

Published: March 2019

AbstractA novel approach has been successfully developed to synthesize Pd@Au core/shell nanosheets by using lemon extract as a biological reducing agent and microwave heating. This approach is suggested to be an eco-friendly, rapid and simple method for the synthesis of Pd@Au core/shell nanosheets. The Au shells that covered the Pd nanosheet surfaces were formed at 80 W in microwave for 20 min. The prepared Pd@Au core/shell nanosheets were characterized by UV–vis spectrophotometry, X-Ray diffraction, transmission electron microscopy, energy dispersive X-ray, energy dispersive X-ray elemental-mapping and energy dispersive X-ray line profile. A highly self-assemblage surface-enhanced Raman scattering methodology was developed by applying Pd@Au core/shell nanosheets for trace fluorescent dye detection. The highest R6G signal was attained with an Au layer of about 3 nm thickness. The results show that the SERS technique is able to detect trace fluorescent dye within a wide concentration range from 10−8 M to 10−17 M, with an extremely low limit of detection of 10−17 M. The study offers a low-cost route to the fabrication of sensing devices capable of use for monitoring cancer progression in natural matrices such as blood.
Novel synthesis of Ti2SC powder using FeS2 as a sulphur source

Published: March 2019

AbstractA novel method is presented for the synthesis of Ti2SC powder by heating FeS2/Ti/TiC mixtures. The phase evolution of Ti2SC was explored in detail with X-ray diffraction, thermo-gravimetry/differential scanning calorimetry, and scanning electron microscopy analysis. It was found that FeS2 began to decompose into activated FeS and released molecular state sulphur at around 500 °C. Subsequently, FeS and Ti underwent a reaction that formed Fe and TiS at 700 °C. Finally, the reaction of both TiS and TiC to form a Ti2SC phase could be triggered at 900 °C. It was confirmed that the Ti2SC phase was obtained with only trace impurity of TiC remaining after acid treatment by microwave hybrid heating of 1.1FeS2/2Ti/2TiC mixtures at 1 300 °C for 3 min. The fine powder with a mean diameter of approximately 1 μm was mainly composed of quasi-spherical particles. Compared to the conventional method, Ti2SC powder was synthesised at a temperature some 300 °C lower and required only 10 % of the heating time.
