Emissions Characteristics for Heavy-Duty Diesel Trucks Under Different Loads Based on Vehicle-Specific Power
Authors: Zhang Shuanghong , Yu Lei , Song Guohua
Published: September 2017

Both operating modes and emissions factors for heavy-duty diesel (HDD) trucks were analyzed under different loads to understand the effect of vehicle loads on emissions. Second-by-second speed data for different loads for HDD trucks were collected first. Then a method for calculating the vehicle-specific power (VSP) values and an emissions model for heavy-duty vehicles by using the VSP value were developed to evaluate the effect of different vehicle loads. The VSP distributions and emissions characteristics for fully loaded and unloaded trucks were analyzed and compared. The results illustrate that the fully loaded vehicles spent more time driving in steady modes and the time percentage of VSP values in the bin of 0 kW/ton for fully loaded trucks was lower than the percentage for unloaded trucks. However, the time percentage at the positive VSP value was significantly higher than the percentage for the unloaded trucks. The emissions factors of fully loaded trucks were significantly higher than those of unloaded trucks. Emissions factors were affected the most at speed intervals of 20 to 40 km/h, with emissions factors for carbon dioxide, carbon monoxide (CO), oxides of nitrogen (NOx), hydrocarbon, and particulate matter (PM) at 20.4%, 23.5%, 29.0%, 11.7%, and 9.4% higher, respectively, than those levels for unloaded vehicles. With an increase of travel speed, the impact of the load on emissions weakened. Vehicle loads had the greatest effect on emissions of NOx, followed by emissions of CO. PM emissions were the least affected by vehicle loads. The impact of vehicle loads on emissions was affected by different acceleration behaviors under different loads.

Published: September 2017

This study demonstrated an approach to modeling individual vehicle second-by-second fuel consumption and emissions on the basis of vehicle operations. The approach used the Motor Vehicle Emission Simulator (MOVES)–Matrix, a high-performance vehicle emissions modeling system consisting of a multidimensional array of vehicle emissions rates (pulled directly from EPA’s MOVES emissions model) that could be quickly queried by other models to generate an applicable emissions rate for any specified on-road fleet and operating conditions. For this project, the research team developed a spreadsheet-based MOVES-Matrix calculator to simplify connecting vehicle activity data with multidimensional emissions rates from MOVES-Matrix. This paper provides a walk-through of the calculation procedures, from basic vehicle information and driving cycles to second-by-second emissions rates. The individual vehicle emissions modeling framework was incorporated into Commute Warrior, a trademarked travel survey application for Android smartphones, to provide real-time fuel consumption and emissions rate estimates from concurrently obtained GPS-based speed data.
Haemoglobin E Trait: A Frequently Incriminated Innocent Trait
Authors: Biswas Akhil Ranjon , Ara Tasneem
Published: September 2017

Background: Haemoglobin (Hb) level in Hb E trait or heterozygous Hb E usually does not go bellow reference level, so does not causes any significant anaemia. However, many medical practitioner conclude Hb E trait as a cause of anaemia when they find Hb E trait in the course of evaluation.Objective:The objective of this case series is to find out whether Hb E trait can be a cause of significant anaemia or not.Methods: A series of cases of Hb E trait with significant anaemia was systematically evaluated to find out the real cause of anaemia and treated accordingly and followed up to find out whether Hb E trait itself can be a cause of anaemia at all.Result: Out of 13 anaemic patients presented with the diagnosis of Hb E trait, 1 was not Hb E tarit at all but Hb E/â thalassaemia. Out of 12 actual Hb E trait, 1 expired within treatment for acute lymphoblastic leukaemia. Correctable cause of anaemia was found in 10 out of remaining 11 cases and 1 case had very high CRP and didnt comply with further investigation. Anaemia was corrected with treatment in 9 cases and partially corrected in 1 case who was not compliant to regular treatment.Conclusion: Hb E trait is not a cause of significant anaemia and a probable incidental finding in anaemic patient undergoing Hb electrophoresis, especially in areas where Hb E is quite common like Bangladesh.J Dhaka Medical College, Vol. 26, No.1, April, 2017, Page 32-35

This was a descriptive cross-sectional study conducted with an aim to assess the level of knowledge and preventive practice regarding hepatitis B among the nurses in Dhaka Medical College Hospital. The study was conducted from January 2015 to June 2015. Total sample was 207 and purposive sampling technique was followed for data collection, which was done by face to face interview. The data were collected on a structured questionnaire and analyzed by SPSS. Out of 207 respondents, majority (54.1%) were found in the age group of 18 to 30 years, where mean age was 33 + 0.2 years. Among them female (83.5%) outnumbered the male (16.4%). Most of them (81.2%) were Muslim. Majority (49.8%) were educated up to HSC level and half of them (51.7%) were married. Majority(45.4%) had family income > 20,000 taka. Most of them (91.8%) had good knowledge that virus was the causative agent of hepatitis B and 84.5% understood infected blood transfusion as common means of disease transmission. About 83.1% had the knowledge about other routes of transmission. Nearly half (51.7%) were not aware of being at risk of infected by HBV but more than half (56.5%) received vaccination for HBV. Most of them (85%) stated that hepatitis B had complications. Mean knowledge score was 8.28 + 2.9, while 80.7% had good level of knowledge, only 19.3% had poor knowledge. Again, mean preventive practice score was 4.78 + 1.3, while 87.4% had good level of preventive practice and 12.6% had poor preventive practice. Here mean practice of prevention was significantly associated with level of knowledge of respondents (P<0.001). In the study overall knowledge and practice was found to be satisfactory. Most of the nursing staffs were at risk of hepatitis B. So appropriate educational and health promotion programs can increase these knowledge & practice further.J Dhaka Medical College, Vol. 26, No.1, April, 2017, Page 36-42

Published: September 2017

Knowledge about the permeability of surrounding rock (salt rock and mudstone interlayer) is an important topic, which acts as a key parameter to characterize the tightness of gas storage. The goal of experiments that test the permeability of gas storage facilities in rock salt is to develop a synthetic analogue to use as a permeability model. To address the permeability of a mudstone/salt layered and mixed rock mass in Jintan, Jiangsu Province, synthetic mixed and layered specimens using the mudstone and the salt were fabricated for permeability testing. Because of the gas “slippage effect”, test results are corrected by the Klinkenberg method, and the permeability of specimens is obtained by regression fitting. The results show that the permeability of synthetic pure rock salt is 6.9 × 10−20 m2, and its porosity is 3.8%. The permeability of synthetic mudstone rock is 2.97 × 10−18 m2, with a porosity 17.8%. These results are close to those obtained from intact natural specimens. We also find that with the same mudstone content, the permeability of mixed specimens is about 40% higher than for the layered specimens, and with an increase in the mudstone content, the Klinkenberg permeability increases for both types of specimens. The permeability and mudstone content have a strong exponential relationship. When the mudstone content is below 40%, the permeability increases only slightly with mudstone content, whereas above this threshold, the permeability increases rapidly with mudstone content. The results of the study are of use in the assessment of the tightness of natural gas storage facilities in mudstone-rich rock salt formations in China.
MicroRNA Signaling in Embryo Development
Authors: Gross Nicole , Kropp Jenna , Khatib Hasan
Published: September 2017

Expression of microRNAs (miRNAs) is essential for embryonic development and serves important roles in gametogenesis. miRNAs are secreted into the extracellular environment by the embryo during the preimplantation stage of development. Several cell types secrete miRNAs into biological fluids in the extracellular environment. These fluid-derived miRNAs have been shown to circulate the body. Stable transport is dependent on proper packaging of the miRNAs into extracellular vesicles (EVs), including exosomes. These vesicles, which also contain RNA, DNA and proteins, are on the forefront of research on cell-to-cell communication. Interestingly, EVs have been identified in many reproductive fluids, such as uterine fluid, where their miRNA content is proposed to serve as a mechanism of crosstalk between the mother and conceptus. Here, we review the role of miRNAs in molecular signaling and discuss their transport during early embryo development and implantation.

Published: September 2017

A series of LiNi0.5Mn1.5O4 (LNMO) samples were synthesized by adjusting the molar ratio of (NH4)2CO3 to Na2CO3 in a mixed precipitant for evaluating the effects of ammonia from (NH4)2CO3 as a complexing agent and Na2CO3 as a precipitant on the morphology and electrochemical performances of LNMO. In this research, a rapid precipitation method followed by hydrothermal treatment was used to prepare the precursors of LNMO, and different molar ratios (0:1, 1:2, 1:1, 2:1, 1:0) of (NH4)2CO3 to Na2CO3 were used for mixed precipitants. The test results revealed that the cathode material exhibits the best electrochemical performance when the molar ratio of (NH4)2CO3 to Na2CO3 is set at 1:2, displaying a specific discharge capacity of 129.4 mA h g−1 at 0.5 C and a capacity retention of 82.3% after 200 charge–discharge cycles. In addition, it still shows a high rate performance with a discharge capacity of 112.7 mA h g−1 at 10 C and 98.8 mA h g−1 at 20 C, which is attributed to an accurate Ni/Mn ratio, smaller primary particle sizes and a porous spherical morphology.
Quantifying Information Modification in Developing Neural Networks via Partial Information Decomposition
Authors: Wibral Michael , Finn Conor , Wollstadt Patricia , Lizier Joseph , Priesemann Viola
Published: September 2017

Information processing performed by any system can be conceptually decomposed into the transfer, storage and modification of information—an idea dating all the way back to the work of Alan Turing. However, formal information theoretic definitions until very recently were only available for information transfer and storage, not for modification. This has changed with the extension of Shannon information theory via the decomposition of the mutual information between inputs to and the output of a process into unique, shared and synergistic contributions from the inputs, called a partial information decomposition (PID). The synergistic contribution in particular has been identified as the basis for a definition of information modification. We here review the requirements for a functional definition of information modification in neuroscience, and apply a recently proposed measure of information modification to investigate the developmental trajectory of information modification in a culture of neurons vitro, using partial information decomposition. We found that modification rose with maturation, but ultimately collapsed when redundant information among neurons took over. This indicates that this particular developing neural system initially developed intricate processing capabilities, but ultimately displayed information processing that was highly similar across neurons, possibly due to a lack of external inputs. We close by pointing out the enormous promise PID and the analysis of information modification hold for the understanding of neural systems.

Published: September 2017

Around the world wind energy is starting to become a major energy provider in electricity markets, as well as participating in ancillary services markets to help maintain grid stability. The reliability of system operations and smooth integration of wind energy into electricity markets has been strongly supported by years of improvement in weather and wind power forecasting systems. Deterministic forecasts are still predominant in utility practice although truly optimal decisions and risk hedging are only possible with the adoption of uncertainty forecasts. One of the main barriers for the industrial adoption of uncertainty forecasts is the lack of understanding of its information content (e.g., its physical and statistical modeling) and standardization of uncertainty forecast products, which frequently leads to mistrust towards uncertainty forecasts and their applicability in practice. This paper aims at improving this understanding by establishing a common terminology and reviewing the methods to determine, estimate, and communicate the uncertainty in weather and wind power forecasts. This conceptual analysis of the state of the art highlights that: (i) end-users should start to look at the forecast’s properties in order to map different uncertainty representations to specific wind energy-related user requirements; (ii) a multidisciplinary team is required to foster the integration of stochastic methods in the industry sector. A set of recommendations for standardization and improved training of operators are provided along with examples of best practices.
Backflow Power Optimization Control for Dual Active Bridge DC-DC Converters
Authors: Xiong Fei , Wu Junyong , Hao Liangliang , Liu Zicheng
Published: September 2017

This paper proposes optimized control methods for global minimum backflow power based on a triple-phase-shift (TPS) control strategy. Three global optimized methods are derived to minimize the backflow power on the primary side, on the secondary side and on both sides, respectively. Backflow power transmission is just a portion of non-active power transmission in a dual active bridge (DAB) converter. Non-active power transmission time is proposed in this paper, which unifies zero power transmission and backflow power transmission. Based on the proposed index, an optimized control method is derived to achieve both the maximum effective power transmission time and minimum current stress of DAB at the same time. A comparative analysis is performed to show the limitations of the minimum backflow power optimization method. Finally, a prototype is built to verify the effectiveness of our theoretical analysis and the proposed control methods by experimental results.

Published: September 2017

We previously prepared ophthalmic formulations containing cilostazol (CLZ) nanoparticles by bead mill methods (CLZnano), and found that instillation of CLZnano into rat eyes supplies CLZ into the retina. In this study, we investigated changes in the electroretinograms (ERG) of streptozotocin-induced diabetic rats (STZ rats), a model of diabetes mellitus. In addition, we demonstrated that dispersions containing CLZ nanoparticles attenuate changes in the ERG of STZ rats. The instillation of CLZnano had no effect on body weight or plasma glucose and insulin levels. Furthermore, no corneal toxicity was observed in the in vivo study using STZ rats. The a-wave and b-wave levels in addition to oscillatory potentials (OP) amplitude decreased in STZ rats two weeks after the injection of streptozotocin, with the instillation of CLZnano attenuating these decreases. In addition, the level of vascular endothelial growth factor (VEGF) in the retinas of STZ rats was 9.26-fold higher than in in normal rats, with this increase also prevented by the instillation of CLZnano Thus, we have found that a-wave and b-wave levels in addition to OP amplitude are decreased in rats following the injection of excessive streptozotocin. Furthermore, the retinal disorders associated with diabetes mellitus are attenuated by the instillation of CLZnano. These findings provide significant information that can be used to design further studies aimed at developing anti-diabetic retinopathy drugs.
Deep Circular RNA Sequencing Provides Insights into the Mechanism Underlying Grass Carp Reovirus Infection

Published: September 2017

Grass carp hemorrhagic disease, caused by the grass carp reovirus (GCRV), is a major disease that hampers the development of grass carp aquaculture in China. The mechanism underlying GCRV infection is still largely unknown. Circular RNAs (circRNAs) are important regulators involved in various biological processes. In the present study, grass carp were infected with GCRV, and spleen samples were collected at 0 (control), 1, 3, 5, and 7 days post-infection (dpi). Samples were used to construct and sequence circRNA libraries, and a total of 5052 circRNAs were identified before and after GCRV infection, of which 41 exhibited differential expression compared with controls. Many parental genes of the differentially expressed circRNAs are involved in metal ion binding, protein ubiquitination, enzyme activity, and nucleotide binding. Moreover, 72 binding miRNAs were predicted from the differentially expressed circRNAs, of which eight targeted genes were predicted to be involved in immune responses, blood coagulation, hemostasis, and complement and coagulation cascades. Upregulation of these genes may lead to endothelial and blood cell damage and hemorrhagic symptoms. Our results indicate that an mRNA–miRNA–circRNA network may be present in grass carp infected with GCRV, providing new insight into the mechanism underlying grass carp reovirus infection.
Esophageal Cancer: Genomic and Molecular Characterization, Stem Cell Compartment and Clonal Evolution
Authors: Testa Ugo , Castelli Germana , Pelosi Elvira
Published: September 2017

Esophageal cancer (EC) is the eighth most common cancer and is the sixth leading cause of death worldwide. The incidence of histologic subtypes of EC, esophageal adenocarcinoma (EAC) and esophageal squamous carcinoma (ESCC), display considerable geographic variation. EAC arises from metaplastic Barrett’s esophagus (BE) in the context of chronic inflammation secondary to exposure to acid and bile. The main risk factors for developing ESCC are cigarette smoking and alcohol consumption. The main somatic genetic abnormalities showed a different genetic landscape in EAC compared to ESCC. EAC is a heterogeneous cancer dominated by copy number alterations, a high mutational burden, co-amplification of receptor tyrosine kinase, frequent TP53 mutations. The cellular origins of BE and EAC are still not understood: animal models supported a cellular origin either from stem cells located in the basal layer of esophageal epithelium or from progenitors present in the cardia region. Many studies support the existence of cancer stem cells (CSCs) able to initiate and maintain EAC or ESCC. The exact identification of these CSCs, as well as their role in the pathogenesis of EAC and ESCC remain still to be demonstrated. The reviewed studies suggest that current molecular and cellular characterization of EAC and ESCC should serve as background for development of new treatment strategies.
The Role of Ion Exchange Membranes in Membrane Capacitive Deionisation
Authors: Hassanvand Armineh , Wei Kajia , Talebi Sahar , Chen George , Kentish Sandra
Published: September 2017

Ion-exchange membranes (IEMs) are unique in combining the electrochemical properties of ion exchange resins and the permeability of a membrane. They are being used widely to treat industrial effluents, and in seawater and brackish water desalination. Membrane Capacitive Deionisation (MCDI) is an emerging, energy efficient technology for brackish water desalination in which these ion-exchange membranes act as selective gates allowing the transport of counter-ions toward carbon electrodes. This article provides a summary of recent developments in the preparation, characterization, and performance of ion exchange membranes in the MCDI field. In some parts of this review, the most relevant literature in the area of electrodialysis (ED) is also discussed to better elucidate the role of the ion exchange membranes. We conclude that more work is required to better define the desalination performance of the proposed novel materials and cell designs for MCDI in treating a wide range of feed waters. The extent of fouling, the development of cleaning strategies, and further techno-economic studies, will add value to this emerging technique.
Spatial Scale Gap Filling Using an Unmanned Aerial System: A Statistical Downscaling Method for Applications in Precision Agriculture
Authors: Hassan-Esfahani Leila , Ebtehaj Ardeshir , Torres-Rua Alfonso , McKee Mac
Published: September 2017

Applications of satellite-borne observations in precision agriculture (PA) are often limited due to the coarse spatial resolution of satellite imagery. This paper uses high-resolution airborne observations to increase the spatial resolution of satellite data for related applications in PA. A new variational downscaling scheme is presented that uses coincident aerial imagery products from “AggieAir”, an unmanned aerial system, to increase the spatial resolution of Landsat satellite data. This approach is primarily tested for downscaling individual band Landsat images that can be used to derive normalized difference vegetation index (NDVI) and surface soil moisture (SSM). Quantitative and qualitative results demonstrate promising capabilities of the downscaling approach enabling effective increase of the spatial resolution of Landsat imageries by orders of 2 to 4. Specifically, the downscaling scheme retrieved the missing high-resolution feature of the imageries and reduced the root mean squared error by 15, 11, and 10 percent in visual, near infrared, and thermal infrared bands, respectively. This metric is reduced by 9% in the derived NDVI and remains negligibly for the soil moisture products.
First Imaging Observation of Standing Slow Wave in Coronal Fan Loops
Authors: Pant V. , Tiwari A. , Yuan D. , Banerjee D.
Published: September 2017

We observe intensity oscillations along coronal fan loops associated with the active region AR 11428. The intensity oscillations were triggered by blast waves that were generated due to X-class flares in the distant active region AR 11429. To characterize the nature of oscillations, we created time–distance maps along the fan loops and noted that the intensity oscillations at two ends of the loops were out of phase. As we move along the fan loop, the amplitude of the oscillations first decreased and then increased. The out-of-phase nature together with the amplitude variation along the loop implies that these oscillations are very likely to be standing waves. The period of the oscillations is estimated to be ∼27 minutes, damping time to be ∼45 minutes, and phase velocity projected in the plane of sky to be ∼65–83 km s−1. The projected phase speeds were in the range of the acoustic speed of coronal plasma at about 0.6 MK, which further indicates that these are slow waves. To the best of our knowledge, this is the first report on the existence of the standing slow waves in non-flaring fan loops.
Trayectorias de clase y percepciones temporales sobre la posición ocupada en la estructura social. Un abordaje multidimensional de las clases sociales. Argentina (2003-2011)
Authors: Lorena Pla Jésica
Published: September 2017

El artículo aborda desde una perspectiva cualitativa las construcciones de sentido, comprendidas como percepciones que los sujetos elaboran con relación a la posición social que ocupan. Lo hace abordando el modo en el que dichos sujetos construyen interpretaciones presentes que incluyen el pasado y el futuro y, a partir de esas elaboraciones, ponen en práctica estrategias para organizar las trayectorias de movilidad social de los integrantes del hogar. La técnica usada fue la de historia de vida, analizadas estas de manera comparativa. De manera general se encontró que el origen social tiene efecto sobre el modo en el cual se construyen dichas percepciones. Las clases sociales mejor posicionadas en la estructura social presentan percepciones relativamente certeras sobre el futuro, referenciadas a las capacidades (propias) de establecer estrategias para lograrlo. En cambio, en quienes experimentan procesos de movilidad intergeneracional de corto alcance y/o de movilidad espuria se observa una idealización del pasado y una inconformidad con el presente que se traduce en incertidumbre con el futuro. En cuanto a las clases trabajadoras, refieren a una mejora en sus condiciones de vida, sustentada en la tríada empleo-seguridad social-consumo y a un contexto (político económico) que mantenga esos elementos.
El declive de la fe en el progreso. Posmaterialismo, ideología y religiosidad en las representaciones sociales de la tecnociencia
Authors: Torres Albero Cristóbal , Lobera Josep A.
Published: September 2017

En las sociedades contemporáneas, las representaciones sociales de la tecnociencia han devenido más complejas y poliédricas, alejándose de las concepciones meliorativas tradicionales. Nuestro trabajo profundiza en el análisis de la creciente importancia de la ambivalencia, así como en el cuestionamiento del modelo del déficit cognitivo como teoría explicativa. Apuntamos que los esquemas cognitivos vinculados a valores posmaterialistas y al nivel de religiosidad tienen un papel decisivo en la conformación de los posicionamientos de la opinión pública sobre aspectos controvertidos de la tecnociencia. Por otro lado, constatamos que estos vínculos varían según las distintas culturas nacionales. En el caso de España, la problematización de las representaciones sociales de la tecnociencia suele estar asociada, de un lado, a las personas con menores niveles de religiosidad y, de otro, con un aumento de las preocupaciones posmaterialistas debido al proceso de secularización de nuestra sociedad.

The determination of the blast protection level of civil engineering buildings components against explosive effects represents a design topic of crucial importance, in current practice. However, some key aspects of blast resistant structures design have been only marginally considered in the last decade, and currently still require appropriate regulations. This is especially true in the case of glass windows and facades, where the intrinsic material brittleness is the major influencing parameter for blast-resistant assemblies. While blast assessment of buildings and systems is usually achieved by means of experimental investigations, as well as Finite-Element numerical simulations, general regulations and guidelines are currently missing.
In this regard, the European Reference Network for Critical Infrastructure Protection - Task Group (ERNCIP-TG) “Resistance of Structures to Explosion Effects” attempts to develop guidelines and recommendations aimed to harmonise test procedures in experimental testing of glass windows under blast, as well as standardized approaches for their vulnerability assessment via Finite Element numerical modelling. In this paper, major ERNCIP-TG outcomes and next challenges are briefly summarized.
Techniques of Non-Destructive Testing of Steel Fiber Reinforced Concrete
Authors: Zezulová Eva , Komárková Tereza
Published: September 2017

Non-destructive testing (NDT) is seeing increasingly frequent use in civil engineering thanks to the fact that the tests are repeatable and do not cause serious damage to the material. The requirements for the development and modernization of available testing devices and methodologies are ever increasing and the testing of existing structures often requires the use of NDT. Unfortunately, every measurement and methodology has its limits and the measurement devices for the evaluation of steel fiber reinforced concrete (SFRC) are no exception. In recent decades there has been an effort to modernize and develop existing measurement devices for SFRC testing. This building material is commonly used especially in large-scale structures. Nevertheless, the technology of SFRC could seem complicated when compared with ordinary concrete and the very nature of this composite material could lead to SFRC inhomogeneity during construction. This paper describes the assessment of SFRC by more or less available methodologies and measurements utilizing non-destructive principles.

Authors: Cibulová Klára
Published: September 2017

The article deals with the mobility during crisis situations. In these situations, there is not always possible to use the roads or ways and the vehicles have to move on different areas, mostly on terrain like meadows, forests etc. That is why we should be able to evaluate whether the terrain is traffiacable or not, whether the vehicles mire or not. The approaches of evaluating the terrain traffiability are described here as well as the instruments used for these purposes, procedures of measuring and calculations. Another aim of this article is to apprise with the means for negotiation the low endurable terrain – traditional wooden and perspective mats.

The aim of solved problem is a development of a new invasive means for improvised explosive devices deactivation. The idea is a quick and reliable disposal of improvised explosive device with construction system as a tube bombe. Such tube bomb has to be deactivated, dismantled and to do not explode. The development of shaped – cumulative charge was conceptually solved in a way to pushed down metal end caps of the tube bomb, to pick up explosive with a detonating fuse and to prevent from its explosion. Dismantled parts put to forensic test, for the improvised explosive device constructer revelation.
Glass Columns under Impact - Experimental and Numerical Analyses
Authors: Bedon Chiara , Kalamar Roman , Eliášová Martina
Published: September 2017

Compared to traditional construction materials, structural glass members subjected to main compression are relatively unusual in buildings, despite a substantially high material compressive strength. The major limit for the use of glass columns is in fact represented by an overall residual load-bearing capacity highly affected by the tensile brittle fracture of glass. An optimal and fail-safe design approach, in this regard, should take care of a multitude of geometrical and mechanical aspects, including boundary details and possible defects, as well as accidental loading scenarios. Aiming to assess the feasibility and vulnerability of structural glass members, based on earlier research efforts, the paper deals on the load-bearing performance of a reference set of full-scale glass columns. Careful consideration is in fact paid for the experimental investigation of glass members with square hollow cross-section and subjected to dynamic impacts, being representative of an accidental loading scenario. Full-scale experimental results are presented, as well as further considered for validation and calibration of Finite Element (FE) numerical models accounting for possible damage propagation in all the structural components, hence allowing to assess the residual load-bearing capacity of the examined structural typology.

The problems related to welding of the high strength steel, aimed for manufacturing of welded structures operating in the prominent wear conditions, is considered in this paper. The paper presents an analysis of possibilities and prescribing the technology for welding the high strength steel HARDOX 450. The methodology for estimate the weldability of this steel was established in the theoretical part of the paper, as well as calculations of the welding parameters, while the hardness was investigated in details and the macro and micro structures of the individual welded joint zones were estimated in the experimental part. Obtained experimental results could be usefully applied for selecting and establishing the optimal welding technology for structures made of this steel. The technology thus established and the GMAW welding regime can enable successful execution of the welded joints and reduce the possibility for appearance of flaws and cracks to a minimum.

Published: September 2017

Anabolic metabolism in lymphocytes promotes plasmablast and cytotoxic T cell differentiation at the expense of self-renewal. Heightened expression and function of the transcription factor IFN regulatory factor 4 (IRF4) accompany enhanced anabolic induction and full commitment to functional differentiation in B cells and CD8+ T cells. In this study, we used a genetic approach to determine whether IRF4 plays an analogous role in Th1 cell induction. Our findings indicate that IRF4 promotes determined Th1 cell differentiation in tandem with anabolic metabolism of CD4+ T cells. IRF4-deficient CD4+ T cells stimulated in vitro exhibit impaired induction of Th1 gene expression and defective silencing of T cell factor 1 expression. IRF4-deficient CD4+ T cells also undergo a shift toward catabolic metabolism, with reduced mammalian target of rapamycin activation, cell size, and nutrient uptake, as well as increased mitochondrial clearance. These findings suggest that the ability to remodel metabolic states can be an essential gateway for altering cell fate.

Palestinian Children in the Hemato-Oncology Ward of an Israeli Hospital
Authors: Nehari Miri , Bielorai Bella , Toren Amos
Published: September 2017

Purpose

An encounter between Palestinian parents of children with cancer and Israeli medical staff is a very special situation where “potential enemies” interact in a caring, trusting and intimate relationship for long periods of time. Our aim was to study the psychological and cultural encounter in order to understand the dynamics involved.

Method

The study is a qualitative one. Data was collected by way of structured in-depth interviews. Participants were physicians and nurses employed in the department, and Palestinian parents accompanying their children who were hospitalized during the research period.

Results

Six main themes emerged from the analysis of the interviews: (1) The decision to come to Israel for treatment. (2) The “meeting points” of the two peoples: the Israeli check points and the Palestinian Authority permits. (3) Encounter with the Israeli hospital. (4) Relationship between medical staff and parents. (5) Language and cultural barriers. (6) Emotions, thoughts and behaviors during high security tension.

Conclusion

The interviews depict a poignant picture of the unique encounter between Israeli Doctors and nurses and Palestinian parents. The psychological mechanism used by parents and doctors is “splitting”-having a dichotomized, simple emotional-perceptual picture of a situation with no conflicts. Nurses use another psychological mechanism in addition which enables them to contain the paradox and the conflict.
