Use of the triglyceride to HDL cholesterol ratio for assessing insulin sensitivity in overweight and obese children in rural Appalachia
Authors: Bridges Kristie Grove , Jarrett Traci , Thorpe Anthony , Baus Adam , Cochran Jill 
Published: August 2015

AbstractStudies have suggested that triglyceride to HDL-cholesterol ratio (TRG/HDL) is a surrogate marker of insulin resistance (IR), but information regarding its use in pediatric patients is limited. This study investigated the ability of TRG/HDL ratio to assess IR in obese and overweight children.The sample consisted of de-identified electronic medical records of patients aged 10–17 years (n=223). Logistic regression was performed using TRG/HDL ratio as a predictor of hyperinsulinemia or IR defined using homeostasis model assessment score.TRG/HDL ratio had limited ability to predict hyperinsulinemia (AUROC 0.71) or IR (AUROC 0.72). Although females had higher insulin levels, male patients were significantly more likely to have hypertriglyceridemia and impaired fasting glucose.TRG/HDL ratio was not adequate for predicting IR in this population. Gender differences in the development of obesity-related metabolic abnormalities may impact the choice of screening studies in pediatric patients.

AbstractWe report the first case of chafer beetle [Anisoplia austriaca(Herbst 1783)] mortality caused byActinomucor elegansvar.elegansin wheat fields of the Kurdistan province, Iran. For three years, dead larvae ofAnisoplia austriacawere collected from wheat fields of the Kurdistan province. Similar isolates of a fast-growing fungus were recovered from all samples. The fungal isolates were identified asA. elegansvar.elegansbased on morphological and cultural characteristics. The identity of the species was further confirmed using sequence data of the ITS (Internal Transcribed Spacer) region of ribosomal DNA. Koch’s postulates were fulfilled by the inoculation of the larvae ofA. austriacaandGalleria mellonella(Linnaeus, 1758) (as the model insect) using the spore suspension ofA. elegansvar.elegans. The viability of sporangiospores was evaluated using a spore dilution technique on germination medium. The results on the pathogenicity (100% mortality inA. austriacalarvae) and viability tests (germination: 95.45%) demonstrated thatA. elegansvar.eleganscan be considered as a potential biocontrol agent against the chafer beetle. Field experiments are still required to evaluate the capacity ofA. elegansas a biological control agent.

AbstractEffects of different pre-planting soil preparations and post-harvest wood debris applications in a clear-cut Scots pine plantation, on the abundance, diversity, and activity of culturable microorganisms were investigated. The investigation was done 9 years after the re-plantings had been done. This formed part of an investigation of silvicultural practices for conservation and the biological control ofArmillariaandHeterobasidionin northern temperate forests (Poland). The treatments being compared, were expected to have altered the soil’s physical and chemical properties, and consequently, its biological properties. Only soft-rot microfungi from the Ascomycota and Zygomycota were detected in the soil. Fungi, including those antagonistic toArmillariaandHeterobasidion, were more abundant after shallow ploughing than after deep ploughing or ridging, and where chipped rather than coarse wood debris was left on the soil surface or incorporated. Scots pine trees had the most biomass and the least mortality after ridging and leaving coarse wood debris on the surface (associated with only a relatively moderate abundance of fungi).

Published: August 2015

AbstractEighteen spring wheat cultivars, recommended for commercial production in northern Poland, were assessed for Fusarium head blight (FHB) in natural non-epidemic conditions, from 2011 to 2013. Assessment was based on FHB incidence (proportion of heads with symptoms), disease severity (DS; proportion of bleached spikelets per head), proportion ofFusariumdamaged kernels (FDK), and spectrum ofFusariumspp. colonising the kernels. Fusarium head blight incidence and DS often differed significantly among cultivars and years. There was a strong positive correlation between FHB incidence and DS. Fusarium head blight incidence and DS were not correlated with the June–July temperatures, and were only occasionally correlated with the total June–July rainfall. There was a weak positive correlation between FHB incidence and proportion of FDK. There was a strong positive correlation between DS and proportion of FDK. The cultivar affected colonisation of kernels byFusariumspp.Fusarium poaewas the FHB pathogen isolated most often.Fusarium poaecolonised 6.0% of the kernels, on average, but up to 12.0% on individual cultivars. OtherFusariumspecies were less frequent:F. avenaceumin 5.6% of kernels,F. culmorumin 5.3%,F. tricinctumin 2.8%,F. graminearumin 1.5%, andF. sporotrichioidesin 1.2%.Fusarium equisetioccurred sporadically. The importance ofF. poaein the FHB complex is emphasised. All cultivars expressed ‘moderate FHB resistance’ if evaluated according to FHB incidence. Cultivars Arabella, Izera, Kandela, Monsun, Ostka Smolicka, and Struna expressed ‘moderate susceptibility’, and Bombona, Hewilla, Katoda, KWS Torridon, Łagwa, Nawra, Parabola, Radocha, SMH 87, Trappe, Tybalt, and Waluta expressed ‘susceptibility’ if evaluated by the proportion of FDK. Cultivars differed within the ‘moderately resistant’, ‘moderately susceptible’, and ‘susceptible’ categories. Cultivars Arabella, Izera, Kandela, Monsun, Ostka Smolicka, and Struna were the most promising and their resistance traits may be useful in FHB management.

Published: August 2015

Abstract
By the use of different distribution methods of dynamical characteristics in the form of slowness function, mechatronic discrete systems have been synthesized. Each model consists of mechanical discrete part and a piezostack actuator connected to LxRxCx external network that has to comply with dynamical requirements in the form of poles and zeros. External network can work within different configurations. In this paper, one investigates the influence of negative parameters of stiffness in mechanical replacement models and capacitance in final mechatronic structures, after dimensionless transformations and retransformations

Published: August 2015

Abstract
In this paper we propose an original configuration of a compliant mini-gripper for handling chemicals. The compliant mini-gripper is 3D modeled and analyzed with finite element method. To use it in a wider range of containers designed for laboratories we made several variants of fasteners. In order to obtain a functional prototype in a scale appropriate to characterize the system, we determined the material properties of the gripper and developed an experimental stand for characterizing the system with mini-gripper. Finally, we compared the movements of the experimental grip, made according to the movement of the bellows type actuator, determined based on, analytical and numerical results

Published: August 2015

Abstract
Nominal strength reduction in cross ply laminates of [0/90]2s is observed in tensile tests of glass fiber composite laminates having central open hole of diameters varying from 2 to 10 mm. This is well known as the size effect. The extended finite element method (XFEM) is implemented to simulate the fracture process and size effect (scale effect) in the glass fiber reinforced polymer laminates weakened by holes or notches. The analysis shows that XFEM results are in good agreement with the experimental results specifying nominal strength and in good agreement with the analytical results based on the cohesive zone model specifying crack opening displacement and the fracture process zone length
Two-Mass Dynamic Absorber of a Widened Antiresonance Zone
Authors: Cieplok Grzegorz , Sikora Marian 
Published: August 2015

Abstract
Attempts to perform synthesis of a passive vibroinsulation two-mass system intended for the simultaneous reduction of machine frame vibrations and forces transmitted to foundations by supporting elements were undertaken in the study. In view of the variable frequency of the machine operation, it was necessary for the frequency interval, encompassed by the vibroinsulation system operation, to be within given limits. On the grounds of properties of the linear massive-elastic system formulated in the works of Genkin and Ryaboy (1998), the problem of vibroinsulation system synthesis was formulated in the parametric type optimisation approach with equality and inequality limitations. For piston compressor vibroinsulation, the mass and elasticity matrices of the vibroinsulating system, as well as its physical structure, were determined. Its operation was verified on the basis of simulation investigations, taking into account the system loss and transient states

Authors: Wolinski Łukasz , Malczyk Paweł 
Published: August 2015

Abstract
The primary importance of the paper is the application of the efficient formulation for the simulation of open-loop lightweight robotic manipulator. The framework employed in the paper makes use of the spatial operator algebra and the associated equations are expressed in joint space. This compact representation of the manipulator dynamics makes it possible to solve the robot forward and inverse dynamics problems in a recursive and fast manner. In the current form, the presented algorithm can be applied for the dynamics simulation of an open-loop chain system possessing any number of joints. Specifically, the formulation has been successfully applied for the analysis of the 7DOF KUKA LWR robot. Results from a number of test cases for the robot demonstrate the verification of the calculations
How Close to Reality is the „as-is” Business Process Simulation Model?
Authors: Gawin Bartlomiej , Marcinkowski Bartosz 
Published: August 2015

Abstract
Background and Purpose: Business process simulation (BPS) model is based on real-life data form sources like databases, observations and interviews. It acts as “as-is” business scenario can used for reengineering. The main challenge is to gather relevant data and to develop simulation model. Research aims to elaborate BPS model and to systematically assess how close to reality it is.
Design/Methodology/Approach: The research has been performed in Polish telecommunications company. Authors investigate technical process of expanding cellular network. After elaborating “as-is” model, authors use ADONIS simulation tool to run a series simulations and confront simulation results with actual historical events. After this, assessment whether computer simulation model can precisely map real-life business process - and consequently act as credible basis for process improvement - is made.
Results: The simulation model has been constructed with data from the WfMS database, observations, staff knowledge and their experience. Fully equipped simulation model is found to allow reconstructing the historical execution of business activity with low margin for error. Some limitation were identified and discussed.
Conclusion: BPS is not a popular approach for process reengineering and improvement yet. Data collection issues for BPS that require adopting process mining techniques and additional information sources are among the reasons for that. In our study, computer simulation outputs are compatible with historical events. Hence the model reflects the business reality and can be taken as a reference model while redesigning the process.
Systems Approach to Standardisation, Classification and Modelling of Managed Events for Tourism
Authors: Jakulin Tadeja Jere , Golob Aleksandra 
Published: August 2015

Abstract
Background and Purpose: The standardisation and classification of managed events provide a legislative basis to distinguish events managed for tourism in their characteristics and quality. The systems approach to standardisation and classification of managed events is a unique, holistic view of event management quality and event organization in tourism. It enables a clear overview of a researched topic and provides adequate support to design and decision-making. In this paper, we explain the meaning of standardisation and classification for Slovenian legislation related to event management. We present the importance of a systems approach methodology for event categorization and classification as it relates to the quality of event management organization, the quality of staff, the quality of the event program and the quality of event services.
Objectives: Provide an overview of events in tourism, related definitions and information gathered from scientific authors, which serves as current systems approach principles with which we want to achieve the desired results, positive changes in legislation; in our case-in the field of managed event quality for tourism through standardisation and classification of events on the national level in Slovenia.
Method: A descriptive method and systems approach methods are fundamental methodological principles in our analysis. In the context of a systems approach, we used qualitative modelling and constructed causal loop models (CLD) of the legislative system of events and investments in the events. We also used context-dependent modelling (SD model) in a frame of systems dynamics.
Results: We present the most appropriate solution to eliminate our problem or question about how to achieve high quality and unique events within event tourism and with event management, thereby creating added value to an event legislative system. We explain suggestions for achieving triple-bottom elements through well-designed quality standards and classification of events, which leads to an optimal categorization of events.
Conclusion: From a systems point of view, event tourism processes, including event management, are systems consisting of people and technologies with the purpose of designing, producing, trading and deploying the idea of an event. It is necessary to transform the current Slovenian legislative system of events and prepare a document which standardizes and classifies events based on systems approach methodology.

Published: August 2015

Abstract
Background and Purpose: The sugar beet is the main field crop used for sugar production in the temperate climatic zone. Since investment in sugar beet industry are long term and ireversible the decision support and economic analysis are required in order to maximise investment returns.
Methodology: A system dynamics methodology was chosen to model the impacts of regional sugar factory investments. We present the basic concepts of system dynamics (SD) models and their development in the case of sugar beet production and processing systems. Sugar beet economics are also analyzed using the static technological economic simulation model.
Results: The simulation provides answers to strategic questions related to the total sugar beet production and processing system and will be used for the simulation of different scenarios for sugar production and their impact on economic and environmental parameters at an aggregate level. Furthermore, the feasibility analysis of sugar beet production revealed that at the current price and intensity levels (yields), we can expect profitable sugar beet production for both white sugar and ethanol.
Conclusion: Preliminary results show that under expected production parameters the sugar beet processing and production would be economically feasible.
Assessment of sodium and potassium levels in soil, feeds and hair of dairy cows in east-central Poland / Ocena poziomu sodu i potasu w glebie, paszach i sierści krów mlecznych z rejonu środkowo-wschodniej Polski
Authors: Górski Krzysztof , Saba Leon 
Published: August 2015

Abstract
Studies were conducted on farm “A” located in east-central Poland to assess the mineral content in cows, taking into account individual links of the soil-feed-animal trophic chain. The mineral assessment included the determination of Na and K. Soil samples were taken once from the humus layer (that is at the depth of 0-15 cm) of pastures and arable fields in mid-growing season by means of a soil sampling stick. Feed samples were taken regularly when the feeds were included in rations (all year round), making sure the samples were representative. Sodium and potassium contents in soil and feeds were determined by the Atomic Absorption Spectrometry methods and in hair by the Inductively Coupled Plasma-Optical Emission Spectrometry method. There were two dates for hair sample collection: I (10-14 days prior to calving) and II (after the first month of lactation). The results showed that Na and K concentrations were sufficient to meet animal needs. The sodium level in cow’s hair fell within the physiological range. Also potassium concentration complied with the referential standards (2000 mg·kg-1 d.m.) and approximated 2040 mg·kg-1 d.m.
Experimental study of penetration interfaces in the overflow fluid-assisted co-injection molding process
Authors: Kuang Tangqing , Yu Chuncong , Xu Baiping , Turng Lih-Sheng 
Published: August 2015

Abstract
The fluid-assisted co-injection molding (FACIM) process can be used to produce hollow plastic products with outer and inner layers. It can be divided into two categories: water-assisted co-injection molding (WACIM) and gas-assisted co-injection molding (GACIM). An experimental study of penetration interfaces in overflow FACIM was carried out based on a lab-developed FACIM system. High-density polyethylene and polypropylene were used as the outer layer and inner layer plastics, respectively, in the experiments and the injection sequence was reversible. Six cross-section cavities were investigated in the experiments. The penetration behaviors of water and gas in different sequences and cavities were compared and analyzed. The penetration interfaces were characterized by the residual wall thickness (RWT). The experimental results showed that the RWT of the inner layer in WACIM fluctuated along the flow direction, while that in GACIM was more even. The difference of viscosity between the outer and inner layer melts affected the stability of the interface between them. The penetration sections of the inner layer and the gas were closer to the cavity sections in GACIM, while the penetration sections of the inner layer and the water were closer to the circular forms in WACIM.
Granulomatosis after autologous stem cell transplantation in nonHodgkin lymphoma – experience of single institution and a review of literature
Authors: Boltezar Lucka , Zagar Ivana , Novakovic Barbara Jezersek 
Published: August 2015

Abstract

Background
Sarcoidosis before and after treatment of malignancy is an important differential diagnosis that has to be distinguished from lymphoma.

Patients and methods
Hodgkin lymphoma, diffuse large B-cell lymphoma and aggressive follicular lymphoma are being staged and treatment effect is evaluated with PET-CT. We report three cases of aggressive lymphoma after high dose therapy and autologous stem cell transplantation with positive lymph nodes on PET-CT, which were histologically diagnosed as sarcoidosis/granulomatosis. In the literature, we found that false positive lymph nodes were more common after allogeneic than after autologous transplantation.

Conclusions
Post-treatment PET-CT positive lymph nodes should always be examined histologically prior to any further treatment decision to avoid unnecessary toxic procedures.
Children of Romanian Migrants between “Here” and “There”: Stories of Home Attachment
Authors: Bratu Roxana 
Published: August 2015

Abstract
By analysing interviews from a larger qualitative study conducted in a Romanian village (Vulturu, Vrancea County) from the South-East region of the country, this paper explores the ways Romanian migrants’ children who were born in the country of origin but migrated to Italy or the so-called 1.5 Generation (Rumbaut 2002; 2012) talk about their ties with the home country. In other words, is Romania presented as more - or something else - than the original homeland?
The study analyses the concept of home attachment in terms of transnationalism understood as affective ties (Huynh and Yiu 2012; Paraschivescu 2011). Based on evidence from interview data a typology of attachment to the home country is outlined and further discussed. The results point to the conclusion that the issue of attachment to the home country is discursively constructed by respondents both explicitly and implicitly by multiple references to the family migration project and their immigrant status at destination. Moreover, I argue that the different types of attachment identified in the interviewees’ discourses are mediated by the subjective assessment of the integration experience into the host country.

Published: August 2015

Abstract
In this study, the effect powder size and matrix temperature on the physical and mechanical properties of SiO2-reinforced Al 7075 matrix composites were investigated. It was observed that with increasing powder size and temperature, infiltration height was increased. Optimum parameters of full infiltration that were determined for particle size and temperature were d50=150 μm and 800°C, respectively. It was also observed that the porosity of the produced composites changed in the range of 3.2–14.6%, and the lowest porosity was obtained from the composite having 105 μm SiO2 particle size. The highest fracture strength (263 MPa) was obtained from the composite produced at a matrix temperature of 800°C and a particle size of 420 μm. It was concluded that particle size and temperature are effective parameters to reach full infiltration, and this method is more suitable for producing the composites that have high reinforcement volume fractions than conventional casting methods.
