What if you are not certain? A common computation underlying action selection, reaction time and confidence judgment
Authors: Christopoulos Vassilios , Enachescu Vince , Schrater Paul , Schaal Stefan
Published: August 2017

From what to wear to a friend’s party, to whether to stay in academia or pursue a career in industry, nearly all of our decisions are accompanied by a degree of confidence that provides an assessment of the expected outcome. Although significant progress has been made in understanding the computations underlying confidence judgment, the preponderance of studies focuses on perceptual decisions, in which individuals sequentially sample noisy information and accumulate it as evidence until a threshold is exceeded. Once a decision is made, they initiate an action to implement the choice. However, we often have to make decisions during ongoing actions in dynamic environments where the value and the availability of the alternative options can change with time and previous actions. The current study aims to decipher the computations underlying confidence judgment in action decisions that are made in a dynamic environment. Using a reaching task in which movements are initiated to multiple potential targets, we show that action selection, reaction time and choice confidence all emerge from a common computation in which parallel prepared actions compete based on the overall desirability of targets and action plans.
On-design exergy analysis of a combustor for a turbojet engine: a parametric study
Authors: Topal Ahmet , Turan Onder
Published: August 2017

Purpose

The purpose of this study is to perform an exergy analysis of a turbojet engine combustor at different cycle parameters.

Design/methodology/approach

Base cycle parameters have been defined for the engine, and then differentiation of the combustor exergy efficiencies and destruction rates have been evaluated by changing overall pressure ratio, combustor exit temperature and combustor pressure ratio.

Findings

For the basic engine cycle, combustor unit is found to have lowest exergy efficiency as 62.3 for the sea level static condition. Compressor turbine exhaust and whole engine exergy efficiencies have been calculated as 88.7, 96.5, 68.2 and 69.4, respectively.

Practical implications

Because of the biggest exergy, destruction is seen mainly in combustion system; effect of the combustor inlet pressure (related to the compressor design technology), pressure drop and exit temperature on the exergy efficiencies have been analyzed and combustor second law efficiency have been evaluated.

Social implications

The investigation’s purposes are highly connected with social wellness and targeted at sustainable development of the society. Practical implementation of the obtained scientific results is directed on the improving of combustor for a turbojet engines and decreasing negative influence on the environment.

Originality/value

As a result of this paper, the following are the contribution of this paper in the field of gas turbine exergy subjects: Combustor has been found as the most critical component in respect of the exergy efficiency. Therefore, the effect of the combustor main cycle parameters such as inlet pressure, combustor pressure ratio and exit temperature have been analyzed.
Development of the college-attendance value scale for second-year students in Taiwan
Authors: Lin Ming-chia , Lin Eric S.
Published: August 2017

Purpose

The purpose of this paper is twofold: to develop the college-attendance value scale (CAVS) in the Taiwan context to understand undergraduates’ reasons for or benefits from college education, and to examine how the value relates to additional motivational goals, academic performance, and expected terminal degree.

Design/methodology/approach

Data analyses involved sophomores (n=729) who completed a learning-experience survey that included CAVS of the personal value and collective value subscales, expected terminal degree, Achievement Goal Questionnaire, and cumulative grade point average (CGPA). Construct validity evidence was substantiated by the results of exploratory factor analysis (n=364) for two-factor identification, and by the results of confirmatory factor analysis (n=365) for a good model-ﬁt.

Findings

The interrelations between variables in regression analysis supported the predictive validity; achievement goals were predictors of CGPA, while personal value was a sole predictor of expected terminal degree. Findings suggest that CAVS is a predictive measure for Taiwanese undergraduates’ academic performance and choices.

Practical implications

In terms of policy implications, college students’ values of college attendance should not only be regularly investigated by institutional research, but should be widely applied by university students, educators and administrators to facilitate the optimal learning development for each undergraduate.

Originality/value

The study develops a short but effective scale of college-attendance value for the Taiwanese students who usually attend college after graduating from high school. The CAVS is useful in manifesting the students’ major reasons for pursuing college education.
The development of Malaysian universities
Authors: Lee Molly , Sirat Morshidi , Wan Chang Da
Published: August 2017

Purpose

The purpose of this paper is to investigate, in general, what are the contemporary external influences that have been dominant in Malaysian universities and what are the major local traditional practices that are also found in these universities.

Design/methodology/approach

From the literature review, the paper proposes a conceptual framework to explore hybridity in governance and management, programs and curriculum, teaching and learning, and research and service.

Findings

Using the conceptual framework, the paper discusses the Malaysian higher education in terms of Western influence and indigenization of Western models, the background context of Islamic universities and seven possible hybridities compiled from anecdotal evidences.

Originality/value

The conceptual framework and possible hybridities identified in the paper serve to provide the guide to a more systemic empirical investigation to examine the characteristics of Malaysian universities emerging from the interaction between external influence and local cultures. The Malaysian case also potentially contribute in exploring the question, “Are Asian universities different from Western universities?”.
Evaluating the mutual pathways among electronic cigarette use, conventional smoking and nicotine dependence
Authors: Selya Arielle S. , Rose Jennifer S. , Dierker Lisa , Hedeker Donald , Mermelstein Robin J.
Published: August 2017

Background and Aims

The implications of the rapid rise in electronic cigarette (e‐cigarette) use remain unknown. We examined mutual associations between e‐cigarette use, conventional cigarette use and nicotine dependence over time to (1) test the association between e‐cigarette use and later conventional smoking (both direct and via nicotine dependence), (2) test the converse associations and (3) determine the strongest pathways predicting each product's use.

Design

Data from four annual waves of a prospective cohort study were analyzed. Path analysis modeled the bidirectional, longitudinal relationships between past‐month smoking frequency, past‐month e‐cigarette frequency and nicotine dependence.

Setting

Chicago area, Illinois, USA.

Participants

A total of 1007 young adult smokers and non‐smokers (ages 19–23 years).

Measurements

Frequency of (1) cigarettes and (2) e‐cigarettes was the number of days in the past 30 on which the product was used. The Nicotine Dependence Syndrome Scale measured nicotine dependence to cigarettes.

Findings

E‐cigarette use was not associated significantly with later conventional smoking, either directly (β = 0.021, P = 0.081) or through nicotine dependence (β = 0.005, P = 0.693). Conventional smoking was associated positively with later e‐cigarette use, both directly (β = 0.118, P < 0.001) and through nicotine dependence (β = 0.139, P < 0.001). The strongest predictors of each product's use was prior use of the same product; this pathway was strong for conventional cigarettes (β = 0.604, P < 0.001) but weak for e‐cigarettes (β = 0.120, P < 0.001). Nicotine dependence moderately strongly predicted later conventional smoking (β = 0.169, P < 0.001), but was a weak predictor of later e‐cigarette use (β = 0.069, P = 0.039).

Conclusions

Nicotine dependence is not a significant mechanism for e‐cigarettes’ purported effect on heavier future conventional smoking among young adults. Nicotine dependence may be a mechanism for increases in e‐cigarette use among heavier conventional smokers, consistent with e‐cigarettes as a smoking reduction tool. Overall, conventional smoking and, to a lesser extent, its resulting nicotine dependence, are the strongest drivers or signals of later cigarette and e‐cigarette use.
Are Attention Check Questions a Threat to Scale Validity?
Authors: Kung Franki Y.H. , Kwok Navio , Brown Douglas J.
Published: August 2017

Attention checks have become increasingly popular in survey research as a means to filter out careless respondents. Despite their widespread use, little research has empirically tested the impact of attention checks on scale validity. In fact, because attention checks can induce a more deliberative mindset in survey respondents, they may change the way respondents answer survey questions, posing a threat to scale validity. In two studies, we tested this hypothesis (N = 816). We examined whether common attention checks—instructed‐response items (Study 1) and an instructional manipulation check (Study 2)—impact responses to a well‐validated management scale. Results showed no evidence that they affect scale validity, both in reported scale means and tests of measurement invariance. These findings allow researchers to justify the use of attention checks without compromising scale validity and encourage future research to examine other survey characteristic‐respondent dynamics to advance our use of survey methods.
From Neo‐Functional Peace to a Logic of Spillover in EU External Policy: A Response to Visoka and Doyle
Authors: Bergmann Julian , Niemann Arne
Published: August 2017

In their recently published JCMS article, Gezim Visoka and John Doyle have proposed the concept of ‘neofunctional peace’ as a means to conceptualize the EU's peacemaking practices in the case of the EU‐facilitated Belgrade‐Pristina dialogue. This article challenges the ‘neo‐functional peace’ on conceptual and empirical grounds. We critically discuss Visoka and Doyle's () reading of neofunctionalism and question parts of their empirical evidence given for the existence of a ‘neo‐functional peace’. Going beyond a mere critique of the article by Visoka and Doyle and arguing that the authors may not have fully exploited neofunctionalism's potential for theorizing EU external policy, we stipulate a neofunctionalist logic for explaining integration in the area of EU external policy. Focusing on three spillover dynamics to explain the initiation of the Belgrade‐Pristina dialogue – functional discrepancies, supranational entrepreneurship and external spillover – we illustrate how neofunctionalism can be used to explain the extension of the scope of EU competences and action in the external policy realm.
Soils and fire jointly determine vegetation structure in an African savanna
Authors: Staver A. Carla , Botha Judith , Hedin Lars
Published: August 2017

Savanna vegetation is variable, and predicting how water, nutrients, and chronic disturbances interact to determine vegetation structure in savannas represents a challenge.

Here, we examined in situ interactions among rainfall, soils, grasses, fire, and elephants that determine tree layer responses to resource gradients in Kruger National Park in South Africa, using 363 long‐term monitoring sites throughout the park.

Grass biomass increased with rainfall and on nutrient‐rich clay soils. Fire frequency, too, increased with rainfall. Conversely, tree density was greater on sandier soils, where water infiltrates more readily, and in areas where the maximum interval between fires was longer, irrespective of average fire frequency. Elephant density responded positively to tree density, but did not contribute significantly to decreasing tree density.

Savanna vegetation structure was reasonably predictable, via a combination of rainfall (favoring grasses), soil (sandy soils favoring trees), and fire (limiting trees until a longer interval between fires allows them to establish). Explicit consideration of bottom‐up and top‐down interactions may thus contribute to a predictive understanding of savanna vegetation heterogeneity.
Factual Evidence without Knowledge
Authors: Conee Earl
Published: August 2017

A central function of our evidence is to constrain the epistemic rationality of our propositional attitudes. Our knowledge does this. That fact supports Timothy Williamson's contention that our evidence is identical to our knowledge, ‘E=K’. But it is argued here that some true propositions are evidence without being known. Some of them cannot be known; others are contingently not known. Propositions play the rational role of evidence whenever they are clearly true, whether or not they are known.
The Nurturing Stance: Making Sense of Responsibility without Blame
Authors: Brandenburg Daphne
Published: August 2017

Mental health‐care clinicians report that they hold patients responsible for morally objectionable behaviour but at the same time consider blaming attitudes to be inappropriate. These practices present a conundrum for all Strawsonian theories of responsibility. In response to this conundrum, Pickard has proposed severing the Strawsonian connection between being responsible and being an appropriate target of blaming attitudes. In this article I will argue that her solution fails to explain the practices at stake and provide an alternative solution that uncovers an under‐theorized stance we take towards those whose abilities are underdeveloped or compromised.
Does intellectual property lead to economic growth? Insights from a novel IP dataset
Authors: Gold E. Richard , Morin Jean‐Frédéric , Shadeed Erica
Published: August 2017

While policymakers often make bold claims as to the positive impact of intellectual property (IP) rights on both developed and developing country economies, the empirical literature is more ambiguous. IP rights have both incentive and inhibitory effects that are difficult to isolate in the abstract and are dependent on economic context. To unravel these contradictory effects, this article introduces an index that evaluates the strength of IP protection in 124 developing countries for the years 1995 to 2011. We illustrate the value of this index to economics study and show evidence that is consistent with IP leading to increased growth. Our results are further consistent with two causal pathways highlighted in the literature: that IP leads to greater levels of technology transfer and increased domestic inventive activity. Yet other aspects of our study fit uneasily with this simple story. For example, we find evidence suggesting that increased levels of growth lead to greater levels of IP protection, contradictory evidence in the literature linking IP with growth, a lack of evidence that increased levels of IP protection lead to actual use of the IP system, and problems with what IP indexes measure. Because of this, we suggest another – and so far undertheorized – explanation of the links between IP and growth: that IP may have few direct effects on growth and that any causality is a result of belief rather than actual deployment of IP.
Longing for homeliness: exploring mealtime experiences of patients suffering from a neurological disease
Authors: Beck Malene , Poulsen Ingrid , Martinsen Bente , Birkelund Regner
Published: August 2017

Background

Many patients suffering from a neurological disease experience eating difficulties during mealtimes in the hospital. Consequently, they often refrain from eating in public places to avoid potentially awkward situations. Eating is an essential part of life, providing patients with comfort during their hospitalisation. Therefore, attention should be paid to these patients, who encounter eating difficulties to foster a positive mealtime experience.

Aim

To study what patients afflicted with a neurological disease experience and assign meaning when participating in mealtimes during hospitalisation.

Method

Ten semi‐structured interviews with patients were conducted and recorded. After transcription the text was analysed, and interpreted compromising three methodological steps inspired by the French philosopher, Paul Ricouer.

Findings

Three themes were identified through data analysis and interpretation: i) The missing feeling of homeliness, ii) The battle between socialisation vs. isolation, and iii) The sense of time, rhythm, and presence.

Conclusions

To patients suffering from a neurological disease, mealtimes are not only a manageable task, but also a part of existential care that leads to positive experience. Aesthetic elements were shown to have the potential of making the patients feel comfortable and homely when hospitalised. This was important, as our study also identified that patients were longing for homeliness when participating in mealtimes during hospitalisation.

Relevance to clinical practice

Our findings emphasised the need of proceeding to interventions that includes mealtime assistance and protects the mealtime activity. Hence, it informs hospital organisations of the importance of restructuring mealtime environment, so that existential care can take place.
A practice model for rural district nursing success in end‐of‐life advocacy care
Authors: Reed Frances M. , Fitzgerald Les , Bish Melanie R.
Published: August 2017

Aim

The development of a practice model for rural district nursing successful end‐of‐life advocacy care.

Background

Resources to help people live well in the end stages of life in rural areas can be limited and difficult to access. District nurse advocacy may promote end‐of‐life choice for people living at home in rural Australia. The lack of evidence available internationally to inform practice in this context was addressed by exploratory study.

Method

A pragmatic mixed method study approved by the University Faculty Ethics Committee and conducted from March 2014 to August 2015 was used to explore the successful end‐of‐life advocacy of 98 rural Australian district nurses. The findings and results were integrated then compared with theory in this article to develop concepts for a practice model.

Results

The model illustrates rural district nurse advocacy success based on respect for the rights and values of people. Advocacy action is motivated by the emotional responses of nurses to the end‐of‐life vulnerability people experience. The combination of willing investment in relationships, knowing the rural people and resources, and feeling supported, together enables district nurses to develop therapeutic emotional intelligence. This skill promotes moral agency in reflection and advocacy action to overcome emotional and ethical care challenges of access and choice using holistic assessment, communication, organisation of resources and empowering support for the self‐determination of person‐centred end‐of‐life goals. Recommendations are proposed from the theoretical concepts in the model.

Limitations

Testing the model in practice is recommended to gain the perceptions of a broader range of rural people both giving and receiving end‐of‐life‐care.

Conclusion

A model developed by gathering and comparing district nursing experiences and understanding using mixed methods and existing theory offers evidence for practice of a philosophy of successful person‐centred advocacy care in a field of nursing that lacks specific guidance.
Thermoeconomic Analysis of Liquid Air Energy Storage System
Authors: Gökçeer Tonguç , Demirkaya Gökmen , Padilla Ricardo Vasquez
Published: August 2017

Liquid Air Energy Storage (LAES) is one of the methods to store energy, which takes the advantage of high expansion ratio of air from liquid state to gaseous state. It uses liquefied air to create a potential energy reserve, by storing air in liquid form at −196°C, in insulated, unpressurized vessels and exposing them to ambient temperatures followed by an electricity generation process by driving a turbine. Off-peak electricity is used to liquefy air, and liquid air will be drawn from the tank, pumped to high pressure and used to drive a turbine to generate electricity when this stored energy is needed. Thermal storage loops (cold recycle) within the cycle as well as integration of waste cold (using the cold released during regasification of LNG) or waste heat (utilizing a waste heat stream during the expansion of air) are the key benefits of this technology and strengthen its competitive position among other energy storage methods.

In this paper, a grid scale, long duration energy storage system based on the liquid air cycle has been analyzed. The performance of a modified LAES system is evaluated to find out critical components and processes, which have a major impact on overall system performance. An economic study has been conducted by assuming a grid-scale LAES operating in Turkish market. LAES appears to be a promising solution as long as its full potential is unlocked by integration of waste cold and waste heat, resulting in an energy dense and cost competitive easily scalable energy storage solution.
Simulation of Tethered Underwater Kites Moving in Three Dimensions for Power Generation
Authors: Ghasemi Amirmahdi , Olinger David J. , Tryggvason Gretar
Published: August 2017

In this paper, a numerical simulation of tether undersea kites (TUSK) used for power generation is undertaken. The effect of varying key design parameters in these systems is studied. TUSK systems consist of a rigid-winged kite, or glider, moving in an ocean current. One proposed TUSK concept uses a tethered kite which is connected by a flexible tether to a support structure with a generator on a surface buoy. The numerical simulation models the flow field in a three-dimensional domain near the rigid undersea kite wing by solving the full Navier-Stokes equations. A moving computational domain method is used to reduce the computational run times. A second-order corrector-predictor method, along with Open Multi-Processing (OpenMP), is employed to solve the flow equations. In order to track the rigid kite, which is a rectangular planform wing with a NACA 0021 airfoil, an immersed boundary method is used. The tension force in the elastic tether is modeled by a simple Hooke’s law, and the effect of tether damping is added. PID control methods are used to adjust the kite pitch, roll and yaw angles during power (tether reel-out) and retraction (reel-in) phases to obtain the desired kite trajectories. During the reel-out phase the kite moves in successive cross-current motions in a figure-8 pattern, the tether length increases and power is generated. During reel-in the kite motion is along the tether, and kite hydrodynamic forces are reduced so that net positive power is produced. The effects of different key design parameters in TUSK systems, such as the ratio of tether to current velocity, and tether retraction velocity, are then further studied. System power output, kite trajectories, and vorticity flow fields for the kite are also determined.
Cyber-Physical System Development Environment for Energy Applications
Authors: Roth Thomas , Song Eugene , Burns Martin , Neema Himanshu , Emfinger William , Sztipanovits Janos
Published: August 2017

Cyber-physical systems (CPS) are smart systems that include engineered interacting networks of physical and computational components. The tight integration of a wide range of heterogeneous components enables new functionality and quality of life improvements in critical infrastructures such as smart cities, intelligent buildings, and smart energy systems. One approach to study CPS uses both simulations and hardware-in-the-loop (HIL) to test the physical dynamics of hardware in a controlled environment. However, because CPS experiment design may involve domain experts from multiple disciplines who use different simulation tool suites, it can be a challenge to integrate the heterogeneous simulation languages and hardware interfaces into a single experiment. The National Institute of Standards and Technology (NIST) is working on the development of a universal CPS environment for federation (UCEF) that can be used to design and run experiments that incorporate heterogeneous physical and computational resources over a wide geographic area. This development environment uses the High Level Architecture (HLA), which the Department of Defense has advocated for co-simulation in the field of distributed simulations, to enable communication between hardware and different simulation languages such as Simulink® and LabVIEW®. This paper provides an overview of UCEF and motivates how the environment could be used to develop energy experiments using an illustrative example of an emulated heat pump system.
Producing Hydrogen From Jet-A Fuel in a Reactor With Integrated Autothermal Reforming and Water-Gas Shift
Authors: Zhang Shuyang , Wang Xiaoxin , Li Peiwen , Xu Xinhai
Published: August 2017

Jet fuel is used to produce hydrogen on board of vehicles through integrated reactions of autothermal reforming (ATR) and water-gas shift (WGS). One of the most attractive benefits of autothermal reforming of hydrocarbon fuels is the possibility of self-sustainability of the reaction if the process is carefully managed and designed. In this work, an integrated fuel processor, including a mixing zone, an ATR reactor, a WGS reactor and two recuperators was fabricated and the hydrogen production performance (using Jet fuel) was tested and studied. Analysis of the energy in reactions and heat transfer area in the heat recuperator was carried out in order to obtain some insights on the optimal design and operating conditions. The previous experimental results regarding the reformate compositions and fuel conversion efficiency were used to evaluate some of the parameters described in the energy analysis model. The predicted results show that the overall process heat was negative (exchanging heat larger than preheating heat) under most of the previous experimental conditions, indicating the potential of self-sustainability of reaction in the fuel processor.

Published: August 2017

As a primitive hexaploid wheat resource distributed only in Tibet, Tibetan semi-wild wheat (Triticum aestivum subsp. tibetanum Shao) possesses unique characteristics that could be exploited in wheat breeding programs. Its good root system could offer a stable platform for above-ground components. To detect possible excellent locus for root traits from Tibetan semi-wild wheat, we identified QTLs for root traits using a recombinant inbred line population derived from a cross between Tibetan semi-wild wheat Q1028 and Zhengmai 9023. A total of 15 QTLs on eight chromosomes were detected, including four major QTLs, QMrl.sau-7B, QTrl.sau-4B, QAd.sau-7A, and QSa.sau-4B. The phenotypic variation explained by each of these QTLs ranges from 5.67% to 16.68%. Positive alleles of six QTLs were derived from Q1028. Several novel QTLs for root traits were identified. In addition, significant correlations were detected amongst root traits and agronomic traits. Taken together, these results suggest that Tibetan semi-wild wheat and the newly identified novel QTLs could be useful in future breeding programs.

Published: August 2017

Background: Pancreaticoduodenectomy (PD) is performed for pancreatic ductal adenocarcinoma (PDA) located at the pancreas head/body. Non-chylous massive discharge after PD is frequently encountered and can cause a vicious cycle of complications associated with severe dehydration and protein loss. Methods: From August 2008 to June 2015, 102 patients who underwent PD for PDA were retrospectively reviewed. High non-chylous discharge was defined as postoperative daily serous discharge exceeding 10 mL/kg. Predictive factors for high non-chylous discharge were assessed using multivariable analysis. Results: Fifty-one patients (50%) developed high non-chylous discharge. Body mass index (BMI) and hemoglobin, total protein, and cholinesterase levels were significantly lower in the high-discharge group compared to the corresponding levels in the low-discharge group. The incidence of postoperative pancreatic fistula and delayed gastric emptying was significantly lower and higher in the high-discharge group than in the low-discharge group, respectively. Multivariable analysis revealed that BMI <22.0 kg/m2, hemoglobin <12.0 g/dL and intraoperative blood loss ≥800 mL were independent predictive factors for high non-chylous discharge. Conclusions: Preoperative low levels of BMI and hemoglobin and intraoperative high blood loss were independent predictive factors for high non-chylous discharge. Improvement of preoperative general and nutritional condition may reduce the incidence of high non-chylous discharge.

Published: August 2017

Enumeration of bacteria is a large component in standard testing of antimicrobial textiles; however, there are multiple plating methods used that are tedious and labor intensive to perform. TEMPO is an instrument that automates much of the enumeration process using the most probable number (MPN) technique. Selective reagents for Staphylococcus aureus (salt) and Pseudomonas aeruginosa (cetrimide) were used to expand TEMPO capability. It was demonstrated that TEMPO had either the same or smaller variance than the traditional spread plating for cells in solution and on textiles tested using AATCC Test Method (TM) 100. TEMPO is a faster and more cost-effective method, and with expanded selective capabilities, can be used to improve enumeration efficiency.

Published: August 2017

Leptin is a 16-kDa peptide hormone secreted by adipose tissue that participates in the regulation of energy homeostasis. The aim of this study was to determine the effect of leptin injection on mRNA expression of peroxisome proliferator-activated receptor gamma (PPAR-Î³) and comparison of PPAR-Î³ mRNA expression in rat's adipose and liver tissue. Twenty adult male rats were divided into the following groups: Group 1asa control (n=10) that did not receive any treatment. Group 2as a treatment (n=10) that received leptin (30 µg â„ kg BW) intraperitoneally (ip) for two successive days. Blood samples were taken before and one day after second leptin injection for triglyceride (TG), Free Fatty Acid (FFA), HLD-cholesterol, and LDL-cholesterol measurement. Total RNA was extractedfrom the adipose tissue and liver tissues of rats.  Adipose and liver tissue cells' cDNA was synthesized to characterize the expression of PPAR-Î³. Gene expression of PPAR-Î³ mRNA was tested by RT- PCR technique. Results show leptin decreases expression of PPAR-Î³ on rat. Low levels of PPAR-Î³ mRNA were detected in adipose and liver tissues of treatment rats in comparison to control group. In treatment group, the level of PPAR-Î³ mRNA in liver tissue was very lower than the adipose tissue. The levels of HDL and FFA in treatment rats were increased whereas serum levels TG, VLDL and LDL were not changed. It is concluded that leptin signal with suppressing of PPAR-Î³ mRNA expression in rat's adipose and liver tissues can result in lipolysis instead of lipogenesis.

Pulmonary diseases cusecs a large portion of mortality in the world. There is no more cure for pulmonary diseases and many approaches are needed for finding ways to cure. Nowadays, implantation and drugs are only ways for curing those people who are facing with these diseases. Tissue engineering and regenerative medicine have been appeared as multidisciplinary field and also, they presents new therapeutic approaches for pulmonary diseases. One of these therapeutic approaches is decellularization which removes cellular but leaves intact important extracellular matrix (ECM) proteins and three-dimensional (3D) architecture and also, this approach has been studied for in-vitro and ex-vivo. In this study, we aimed to investigate a comparison of different concentrations of Triton X-100 and Sodium dodecyl sulfate detergents in lung decellularization in order to evaluate the effects of different concentrations and times of mentioned detergents on three dimensional and ECM proteins lung. Two detergents (Triton-X100 and Sodium dodecyl sulfat) were used with different concentrations for decellularizing rat lungs for maintaining of three-dimensional lung architecture and ECM protein compositions which have significant roles in differentiation and migration of stem cells. Results showed that SDS 0.05%, 0.1% and Triton-X100 0.1% could maintain 3D, elastin and collagen better than other concentrations in 24 and 48 h- decellularization. We concluded that these approaches can help to achieve three-dimensional architecture and extracellular matrix of lung with minimum destruction for next step such as recellularization and in-vivo study.
Anion-directed assembly of lanthanide coordination polymers with SMMs properties based on a dihydrazone ligand

Four new Ln(III)-based coordination polymers (CPs), [Eu(HL)Cl2(DMF)2]·(H2L) (1), [Dy(HL)Cl2(DMF)2]·(H2L) (2), [Er(HL)Cl2(DMF)(CH3OH)]·(DMF) (3) and [Yb(HL)Cl2(DMF)(H2O)]·(DMF) (4) (H2L=2,6-bis[(3-methoxysalicylidene)hydrazinocarbonyl]pyridine) have been synthesized through the reaction of Ln(III) chloride and H2L by using the vapour diffusion method. Interestingly, Cl− as a template agent plays a vital role in the formation of the target complexes. Single-crystal X-ray diffraction studies indicate that 1 and 2 are isostructural and crystallize in triclinic space group P1̅, while complexes 3 and 4 are isostructural and crystallize in monoclinic space group C2/c. Variable temperature magnetization measurement (χ
M
T–T) demonstrates possible antiferromagnetic interactions in complex 2. Alternating-current (ac) susceptibility measurement furthermore indicated frequency dependence for both the in-phase (χ′) and out-of-phase (χ″) components in 2, suggesting that there is a slow relaxation behavior of the magnetization, which is typical of single-molecule magnets (SMMs). This is the first time that Ln(III) CPs based on such a dihydrazone ligand has been reported so far.

Bilješke uz naronitanski spomenik CIL 3 8438
Authors: Maršić Dražen
Published: August 2017

U radu se raspravlja o znamenitom, ali nažalost izgubljenom naronitanskom nadgrobnom spomeniku CIL 3, 8438 s dona militaria i centurionskim insignijima na čeonoj strani. Ukazuje se na zanimljivi način na koji je izgubljen, tipološku pripadnost spomenika, jedan neprimijećeni element ikonografije (vitis), a na kraju se predlaže i datiranje. Usputno se osvrće i na složenu problematiku postrojbe u kojoj je pokojnik služio u trenutku smrti, tj. pitanje jesu li kohorta Camp. bez ili s rednim brojem I jedna ili dvije postrojbe.

Dijalog i jednostavna prošla glagolska vremena u "Brižinskim spomenicima" i glagolskim prenjima
Authors: Kuvač-Levačić Kornelija
Published: August 2017

Rad istražuje nazočnost zajedničkih stilističkih odrednica što ih dijele "Brižinski spomenici" (prvi i treći su liturgijske formule skupne ispovijedi, a drugi, koji se još naziva i "Adhortatio ad poenitentiam", homiletički je nagovor na sakrament ispovijedi) i hrvatska glagoljska prenja. Glavni interes svih triju spomenika, baš kao i u prenjima, jest kako prikazati ideju kozmičkog sukoba između Dobra i Zla. Srednjovjekovni autor nema druge mogućnosti osim stilogeneuporabe jezičnih sredstava, u ovom slučaju dijaloških struktura i uporabe određenih glagolskih oblika (jednostavnih prošlih).
Propovijedi Vicka Zmajevića
Authors: Babić Vanda
Published: August 2017

Vicko je Zmajević (1670.-1745.) nesumnjivo jedna posebna, skladna i jaka osobnost koja je djelovala na raznim društvenim područjima koja su se u njegovu radu međusobno nadovezivala i nadopunjala. Sve što je radio, pisao i zalagao se bilo je u interesu hrvatskog čovjeka i Katoličke crkve. Razgovor Duhovni zbirka je propovijedi koju je Zmajević pisao između 1682. i 1685. godine kao dvanaestogodišnji dječak. Original se čuva u Nadžupskom arhivu u Perastu i to je jedino Zmajevićevo djelo pisano hrvatskim jezikom.  Sve njegove propovijedi odišu baroknom poetičnosti, citatima, metaforama i antitezama, a grafijska slika potvrđuje nam priraslost Boke kotorske s hrvatskim duhovnim prostorom. Autorica Zmajevićeve propovijedi stavlja u okvir barokne propovjedne književnosti otkrivajući nam do sada slabo istraženu Zmajevićevu zbirku.
Dva natpisa iz Boke s imenom biskupa Ivana
Authors: Lončar Milenko
Published: August 2017

U kotorskom natpisu autor predlaže popravke dosadašnjih čitanja, ponajprije Kovačevićeva, čime se vraća usklađenost godine s indikcijom; interpretacija time dobiva na uvjerljivosti.Na dosad nerazumljivu početku natpisa iz Bijele vidi mogućnost prepoznavanja carske titule, a vjerojatno i imena samog cara, Nikefora I. Oba se natpisa na taj način međusobno podupiru i potvrđuju shvaćanje da se doista radi o istom, kako izgleda, vrlo poduzetnom biskupu s početka 9. stoljeća.
Marijanske pjesme u prijepisu Gašpara Vučića
Authors: Sambunjak Slavomir
Published: August 2017

Člankom pozivamo znanstvenu javnost da pažljivo čita glagoljsku prozu, ne bi li u njoj prepoznala stihove, i da čita asilabičke stihove, ne bi li u njima prepoznala izvorno silabičke, ali iskvarene i prilagođene molitvenoj svrsi. Uvjereni smo da su pobožni pisari  pjesme pretvarali u molitve tako da su ih lišavali pjesničkih rekvizita, posebice ritma i rime. Stilističkom metodom supstitucije nastojali smo pokazati taj postupak pisara na primjeru Molitvenika Gašpara Vnučića iz 16. stoljeća: naizgled prozni tekstovi, molitve upućene Mariji i Kristu, u našoj su rekonstrukciji konačno poprimili čvrstu stihovnu formu. Lingvističkom analizom dokazivali smo proces kvarenja izvornih pjesama, odnosno izvršili smo rekonstrukciju. Siromašnu korpusu hrvatskih marijanskih pjesama tako smo dodali nekoliko novih, dosad nepoznatih pjesama. Pretežito su, uvjereni smo, izvorno bile napisane u osmercima i distisima, s rimama i asonancama, sasvim uobičajeno za hrvatsko religiozno pjesništvo s kraja srednjovjekovlja.
Društveni i politički ideologemi hrvatske fantastične proze (na primjeru Desnice, Čuića i Brešana)
Authors: Kuvač-Levačić Kornelija , Car Amanda
Published: August 2017

This paper defines the ideologeme and deals with ideologemic structures in the selected works by Vladan Desnica, Stjepan Čuić and Ivo Brešan. It explains why these Croatian writers turn to fantasy genre and what their position is in relation to the authority. All three authors break the ideological concepts, but they do it in different ways, so it is revealed how the ideologemic structures of their fantastictexts work. An answer is also given to the question as to whether fantasy prose functions as an ideologemic structure at all.

Published: August 2017

La tomografía computarizada (TC) es uno de los grandes avances tecnológicos utilizados en medicina para el diagnóstico de enfermedades, sin embargo es también una técnica usada en otras áreas, tales como química aeroespacial, radioastronomia, etc. El objetivo de la TC es reconstruir la parte interna de un objeto sin tener la necesidad de abrirlo, dicho procedimiento es conocido como ensayo no destructivo. Para lograr dicho propósito, la TC usa la atenución que sufren los rayos X al atravesar por dicho objeto con dicha información se reconstruye la parte interna del objeto, es decir un problema inverso. En este artículo nos salimos de la teoría y nos centramos en la práctica mostrando de manera concreta cómo se reconstruye la parte interna de un objeto usando un método algebráico conocido como reconstrucción algebráica.
