Asymmetry costs: Effects of wing damage on hovering flight performance in the hawkmothManduca sexta
Authors: Fernández María José , Driver M. Ellis , Hedrick Tyson L. 
Published: August 2017

Flight performance is fundamental to the fitness of flying organisms. Whilst airborne, flying organisms face unavoidable wing wear and wing area loss. Many studies have tried to quantify consequences of wing area loss to flight performance with varied results; suggesting that not all types of damage are equal and different species may have different means compensating for some forms of wing damage with little to no cost. Here, we investigate the cost of control during hovering flight with damaged wings, specifically wings with asymmetric and symmetric reductions in area, by measuring maximum load lifting capacity and the metabolic power of hovering flight in hawkmoths (Manduca sexta).We found that while asymmetric and symmetric reductions are both costly in terms of maximum load lifting and hovering efficiency, asymmetric reductions are approximately twice as costly in terms of wing area lost. The moths also did not modulate flapping frequency and amplitude as predicted by a hovering flight model, suggesting that the ability to do so, possibly tied to asynchronous versus synchronous flight muscles, underlies the varied responses found in different wing clipping experiments.
Shifting Blame? Experimental Evidence of Delegating Communication
Authors: Garofalo Orsola , Rott Christina 
Published: August 2017

Decision makers frequently have a spokesperson communicate their decisions. In this paper, we address two questions. First, does it matter who communicates an unfair decision? Second, does it matter how the unfair decision is communicated? We conduct a modified dictator game experiment in which either the decision maker or a spokesperson communicates the decided allocation to recipients, who then determine whether to punish either of them. We find that receivers punish both the decision maker and the spokesperson more often, and more heavily, for unfair allocations communicated by the spokesperson if there is room for shifting blame. The increased punishment results from the messenger’s style of delivery: spokespersons are more likely than decision makers to express emotional regret instead of rational need. Receivers seem to punish the former style of communication because they view it as an attempt to shift blame. Our results establish more generally that the design of communication schemes shapes relationships among organizational members.

Results of directly applied activated carbon cloth in chronic wounds: a preliminary study
Authors: Scheer H.S. , Kaiser M. , Zingg U. 
Published: August 2017

Objective: Activated carbon (AC) has been used in wound therapy as an active substance inside dressings. Applying AC directly on a wound is a new concept. The aim of this study was to analyse the outcomes of chronic wounds which were managed with directly applied activated carbon knitted cloth (ACC, Zorflex) in Swiss patients. Method: A retrospective analysis of the records of all patients with chronic wounds treated with ACC between 1 October 2013 and 31 December 2015 in an outpatient wound clinic. Chronic was defined as a wound being present for >3 weeks. Malignant wounds were excluded. The main outcome was the time to complete closure or readiness for spilt-thickness skin grafting (STSG). Descriptive data, including nutritional status and angiology results were obtained. Results: There were 36 women and 34 men, median age 68 years old. The median body mass index (BMI) 28.1kg/m2 and 76% (n=53) of patients had comorbidities. Angiology exam results showed signs of reduced arterial perfusion in 13% (n=9) of patients and malnutrition in 11% (n=8). Of the wounds included 34% (n=24) were on the trunk and 66% (n=46) on the extremities. The median wound size was 6.9cm2 (range: 0.1-300cm2). The wounds on the trunk were larger than wounds on extremities (10 versus 2cm2). Overall, median time to wound closure was 51 days. In 94% (n=66) of patients, wounds closed without further intervention and 6% (n=4) underwent STSG. Patients with comorbidities showed longer wound healing times compared with those without. No adverse events such as allergies or skin irritation occurred. Cost analysis, including personnel and material and stratified according known wound closure times, showed ACC (US$ 1252) to be like hydrocolloids (US$ 1128), but substantially lower than white gauze (US$ 3026) and negative pressure wound therapy (NPWT) (US$ 2578). Conclusion: ACC applied directly on chronic wounds of different aetiology is safe with short closure times. The cost efficiency is high. It combines the positive features of other wound dressings, such as hydrocolloids and NPWT, without their disadvantages. The dressing change of ACC is easy and non-specialised nurses or even patients themselves can be taught to perform it.
Defining land rights in Dutch Sri Lanka
Authors: Rupesinghe Nadeera 
Published: August 2017

Abstract
The Dutch East India Company (Verenigde Oostindische Compagnie [VOC]) set up a judicial forum of European and native officials called the Landraad in parts of early modern Sri Lanka. Its primary tasks were to hear certain civil cases and maintain the thombo (land register). The VOC wished to define who could do what in which piece of land and what it could extract in return. This article is a study of land rights in southern Sri Lanka, providing quantitative and qualitative evidence on the types of possession recognized by the VOC. Officials used local terms relating to land tenure in the thombo, the Landraad and other discussions. The thombo and the Landraad were in effect the legal mechanisms by which the conversion of land, whether collectively or individually held, into alienable title was sought to be consolidated. Despite the complexities of the local land tenure system, the VOC attempted to enforce rules and regulations that would create a neat, circumscribed system that followed specific legal procedures and written forms. This was not always achieved in practice, indicating the important yet discreet role played by peasants in defining land rights.

Published: August 2017

In the article the lexical units gathered from all history of Polish language were put under investigation belonging to the word family of the noun – paskuda. By using the semasiological method the researched process of how particular formations formed the new semantical senses manifested itself and how eradicated the old ones. The general key of its movings and the purpose were underlined and of these modifications ‘in the better serving’ depicted.As shown the afore-mentioned lexical units comprised with a multitude of senses already by-gone featuring the adultery, the burglary, defamation, gluttony and the cattle disease. At the beginning they seemed stable nevertheless the overuse of them paradoxically caused the eradication of popular meanings. They were not forgotten fully because it’s ‘residua’ were found in folk-slang. The essential figure is hereditary of pre-Slavic senses for instance; ‘something shoddy<poor>’, ‘something off’, ‘something repulsive’. Nowadays they function primarily in written material of all lexical family of the noun – paskuda.
Entwicklung eines Kuppelwinkelreglers für
GuD-Einwellen-Kraftwerke
Authors: Zimmer Gerta , Pieper Daniel , Bennauer Martin 
Published: August 2017

Zusammenfassung
Eine Hauptbauform im
Bereich der großen Kraftwerke ist die GuD (Gas- und
Dampf) Konfiguration. Dabei wird die Abhitze von einer
oder mehreren Gasturbinen verwendet, um Dampf zu
erzeugen und damit eine nachgeschaltete Dampfturbine zu
betreiben. Bei einem
GuD-Einwellen-Kraftwerk wird ein
einziger Generator sowohl durch die Gas- als auch durch
die Dampfturbine angetrieben. Bei dieser Bauform sind
Gasturbine und Generator starr gekoppelt, die
Dampfturbine überträgt das Moment hingegen über eine
synchronisierende,
selbst-schaltende Kupplung.
Beim Hochfahren kuppelt die Dampfturbine normalerweise in einem beliebigen
Winkel relativ zur
Gasturbinen-/Generatorwelle. Es
gibt nun Turbinenstränge, bei denen aus
betrieblichen Gründen ein bestimmter Winkelbereich bevorzugt
wird. Aus diesem Grund wurde eine Regelung
entwickelt, die das Einkuppeln in einem definierten
Winkelbereich ermöglicht.
Die Stabilität und Robustheit gegenüber Störgrößen
(schwankende Netzfrequenz) und Parameterunsicherheiten wurde zunächst
simulationsbasiert untersucht. Das Konzept wurde
leittechnisch umgesetzt und die Performance des Reglers in
Hardware-in-the-loop-Tests
validiert. Auch die darauf folgende Erstimplementierung
in einem niederländischen Kraftwerk war erfolgreich,
die vorgegebene Genauigkeit konnte gesichert erreicht
werden.
Dieser Beitrag zeigt die Entwicklungsschritte, die
systemtechnisch vorgegebenen Randbedingungen sowie Auswertungen der
erfolgten Implementierungen.
Über die Existenz einer separierten Koordinatendarstellung für unteraktuierte mechanische Systeme

Published: August 2017

Zusammenfassung
Die Modellbildung unteraktuierter mechanischer Systeme führt auf ein System nichtlinearer verkoppelter
Differentialgleichungen zweiter Ordnung. Die rechte Seite beschreibt dabei die Wirkung externer (verallgemeinerter)
Kräfte, d. h. des Systemeingangs, wobei dessen Komponenten über eine im Allgemeinen konfigurationsabhängige
Matrix den einzelnen Differentialgleichungen zugeordnet werden. In der Literatur wird allerdings oft angenommen, dass die
Konfigurationskoordinaten und der Eingang so gewählt werden können, dass sich eine Zerlegung in ein vollständig aktuiertes
und ein nichtaktuiertes Teilsystem ergibt. Dieser Beitrag stellt ein Kriterium vor, wann eine solche Koordinatenwahl
möglich ist. Dazu werden die Theorie der Differentialformen und der Satz von Frobenius herangezogen.
Auf die praktische Auswertung des Kriteriums wird anhand von drei Beispielen eingegangen.
Simultaneous Carbon Capture and Reuse Using Catalytic Membrane Reactor in Water-Gas Shift Reaction
Authors: Saw Shuey Zi , Nandong Jobrun 
Published: August 2017

Abstract
Hydrogen (H2) has been recognized as one of the attractive energy carriers due to its clean and environmentally friendly characteristics where the burning of H2 as a fuel produces zero waste emission. Water-gas shift reaction (WGSR) has been accepted as one promising pathway for producing hydrogen. Recently, membrane technology has emerged as a new way to improve high-purity H2 production via the WGSR. A substantial amount of research works has so far focussed on the production of H2 alone while often neglecting the emission of carbon dioxide (

$CO_2$

C

O

), a greenhouse gas that is known to be the culprit responsible for global warming. Addressing the conflicting issues between clean H2 fuel and environmentally adverse

$CO_2$

C

O
2

emission requires a systematic engineering approach to carbon capture to be incorporated directly into H2 production plant. In view of this, the reuse of

$CO_2$

C

O
2

can be implemented by incorporating the dry methanation reaction. In the proposed reuse strategy, the WGSR uses carbon monoxide (CO) and water as the reactants while the dry methanation reaction uses

$CO_2$

C

O
2

and methane (CH4) to produce CO and H2. Based on two case studies of industrial plants, this paper presents a rigorous evaluation of the technical and economic feasibility of the implementation of this reuse strategy by using H2 selective membrane reactor (MR). Upon extensive analysis of different strategies with and without carbon capture technology, it is found that with the proposed carbon capture strategy, the industrial plants show positive improvement in terms of both technical and economic performances.
The Effect of Various Components of Triglycerides and Conversion Factor on Energy Consumption in Biodiesel Production

Published: August 2017

Abstract
Major components of triglycerides in palm oil are palmitic acid, oleic acid, and linoleic acid, in which the presence of these components effects the final purity of a biodiesel. Since reaction process and type of catalyst influence the composition of the free fatty acid (FFA) ASPEN HYSYS was used to simulate a biodiesel production process. Furthermore, higher yield of biodiesel was desired to increase its efficiency as fuel application. Palm oil was taken as the raw material at different components of FFA wt% by using sulphated zirconium (SZ) as the catalyst. Three simulations of biodiesel production processes were performed using ASPEN HYSYS based on 99 % of conversion factor to determine the energy consumption and the results were compared. The conversion factor for each component and the mixture of all of the components was discussed. Results showed that triolein with 0.12 wt% of oleic acid produced 99.75 % of biodiesel, while tripalmitin with 0.5 wt% of palmitic acid is the most abundant FFA in palm oil producing 99.67 % of biodiesel. The total energy consumption in the three processes were different because, different types of feedstocks and unit operations arrangements have been used.

Published: August 2017

Abstract
A double acceptance sampling plan (DASP) based on truncated life tests is
suggested in this paper when the lifetime of a product follows the
exponentiated generalized inverse Rayleigh distribution (EGIR). For a fixed
value of the consumer’s confidence level, the minimum sample sizes of the
first and second samples needed to ensure the specified mean life are
obtained. The operating characteristic values according to the different
quality levels are obtained and the minimum ratios of the mean life to the
specified life are calculated. The important tables based on the suggested
DASP are calculated and illustrated.

Authors: Atıci Emine , Mogulkoc Rasim , Baltaci Abdulkerim Kasım , Menevse Esma 
Published: August 2017

Abstract

Background
Changes in thyroid hormone concentrations may affect adiponectin concentrations through various mechanisms. A molecule released primarily from the fat cells adiposities; adiponectin has important effects on the regulation of body weight.

Aim
The present study aimed to explore the effects of experimental thyroid dysfunction and its treatment on nesfatin-1 and adiponectin levels in rats.

Methods
The study included 40 adult male Sprague-Dawley rats which were grouped as follows: (1) control; (2) hypothyroidism [hypothyroidism was induced by intraperitoneal injection of 10 mg/kg/day propylthiouracil (PTU) for 3 weeks]; (3) hypothyroidism + thyroxine group [after hypothyroidism was induced by 2-week PTU injection, they were treated with high-dose L-thyroxine (1.5 mg/kg/day) for 1 week]; (4) hyperthyroidism [hyperthyroidism was induced by 3-weeks’ thyroxine injection (0.3 mg/kg/day)]; (5) hyperthyroidism + PTU (after hyperthyroidism was induced by 2-weeks’ thyroxine injection, the animals were given 10 mg/kg/day PTU for 1 week). Blood samples taken at the end of the study were analyzed to measure nesfatin-1 and adiponectin levels.

Results
It was found that nesfatin-1 levels increased in hypothyroidism, while adiponectin levels decreased (p < 0.001). In experimental hyperthyroidism, on the other hand, both nesfatin-1 and adiponectin levels were found significantly elevated (p < 0.001).

Conclusion
The results of the study indicate that nesfatin-1 and adiponectin levels were modified considerably in hypo- and hyperthyroidism, whereas with the restoration of the thyroid function, modified hormone levels went back to normal.
La-, Mn- and Fe-Doped Zirconia Washcoats Deposited on Monolithic Reactors via Sol-Gel Method: Characterization and Evaluation of their Mass Transfer Phenomena and Kinetics in Trichloroethylene Combustion
Authors: Rivera De la Rosa Javier , Lucio-Ortiz Carlos J , Pedroza-Solís Celia D , De Haro-Del Rio David , García Tomás Hernández 
Published: August 2017

Abstract
La-, Mn- and Fe-doped ZrO2 was synthesized using the sol-gel method, washcoated on cordierite monoliths and used in trichloroethylene (TCE) combustion. A sol from sol-gel synthesis method was used to obtain the zirconia washcoatings. The washcoatings deposited on the cordierite monolith materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and N2 physisorption measurements, being the crystalline phase determination the most correlate with the catalytic activity. The washcoat properties were correlated to their performance in trichloroethylene combustion. The catalytic washcoatings contained a mixture of crystalline tetragonal ZrO2 and monoclinic ZrO2, and the monoclinic phase exhibited strong interactions with the α-cordierite crystalline phase. For the kinetic tests, the mass transfer into the washcoated monolith channels was evaluated using a recently developed model for the internal mass transfer coefficients for diffusion and reactions in catalytic monoliths. This model involves three resistances. In a plot of the overall resistance as function of the Thiele modulus was determinate that he reaction occurred in the kinetically controlled regime. The kinetic data were fit to two Langmuir–Hinshelwood (LH) models, and the reaction rate was fitted as a function of the trichloroethylene inlet concentration. The adsorption parameters obtained with both LH models were validated based on thermodynamic criteria for the changes in the standard enthalpy of adsorption(${\Delta}H_{ads}^0$) and standard total entropy of adsorption (${\Delta}S_{ads}^0$). It was found that adsorbed TCE and oxygen atoms should be more mobile over the catalyst, which had a higher proportion of tetragonal phase than monoclinic phase of zirconia. The La, Fe-doped catalyst exhibited the highest activity, mainly due the presence of tetragonal zirconia.

Anisotropic excitation of surface plasmon polaritons on a metal film by a scattering-type scanning near-field microscope with a non-rotationally-symmetric probe tip

Published: August 2017

Abstract
We investigated the excitation of surface plasmon polaritons on gold films with the metallized probe tip of a scattering-type scanning near-field optical microscope (s-SNOM). The emission of the polaritons from the tip, illuminated by near-infrared laser radiation, was found to be anisotropic and not circularly symmetric as expected on the basis of literature data. We furthermore identified an additional excitation channel via light that was reflected off the tip and excited the plasmon polaritons at the edge of the metal film. Our results, while obtained for a non-rotationally-symmetric type of probe tip and thus specific for this situation, indicate that when an s-SNOM is employed for the investigation of plasmonic structures, the unintentional excitation of surface waves and anisotropic surface wave propagation must be considered in order to correctly interpret the signatures of plasmon polariton generation and propagation.
