Coincidence point and fixed point theorems for a new type of G-contraction multivalued mappings on a metric space endowed with a graph
Authors: Hanjing Adisak , Suantai Suthep 
Published: September 2015

AbstractIn this paper, a new type of G-contraction multivalued mappings in a metric space endowed with a directed graph is introduced and studied. This type of mappings is more general than that of Mizoguchi and Takahashi (J. Math. Anal. Appl. 141:177-188, 1989), Berinde and Berinde (J. Math. Anal. Appl. 326:772-782, 2007), Du (Topol. Appl. 159:49-56, 2012), and Sultana and Vetrivel (J. Math. Anal. Appl. 417:336-344, 2014). A fixed point and coincidence point theorem for this type of mappings is established. Some examples illustrating our main results are also given. The main results obtained in this paper extend and generalize those in (Tiammee and Suantai in Fixed Point Theory Appl. 2014:70, 2014) and many well-known results in the literature.

AbstractWe herein describe the case of a 29-year-old woman with type 1 diabetes from 10 years of age who developed adult cyclic vomiting syndrome. Beginning at 25 years of age, she was frequently hospitalized for stress-induced vomiting. Her vomiting episodes developed acutely and remitted after severe vomiting of more than 30 times a day for a few days. The vomiting periods were accompanied by leukocytosis with a predominance of neutrophils, high blood pressure and fever. In addition, it was noted that her levels of both adrenocorticotropic hormone and antidiuretic hormone during the vomiting attacks increased and subsequently dramatically decreased immediately after symptom improvement; therefore, she was diagnosed with adult-type cyclic vomiting syndrome in accordance with the diagnostic criteria of Rome III, a system developed to classify functional gastrointestinal disorders. Though glycemic control had improved with continuous subcutaneous insulin infusion therapy, the vomiting frequency increased due to the failure of drug treatments and general psychotherapy to terminate the vomiting attacks, making discharge difficult and greatly interfering with everyday life. Eventually, hypnotherapy and miniature garden therapy were prescribed, which significantly reduced the vomiting frequency, making it possible to discharge her from inpatient medical care.In the treatment of this patient with type 1 diabetes and adult-type cyclic vomiting syndrome, continuous subcutaneous insulin infusion therapy and comprehensive psychotherapy were effective.
Ambient seismic noise tomography at Ekofisk
Authors: de Ridder Sjoerd A. L. , Biondi Biondo L. 
Published: September 2015

We have studied an approximately 40-hr recording from the Life of Field Seismic array installed over Ekofisk field to assess whether the recorded ambient seismic energy was suitable for passive seismic surface-wave interferometry. Passive seismic interferometry aims to retrieve virtual seismic sources by crosscorrelation. We have found that the noise recorded by the pressure sensors between 0.4 and 1.4 Hz consisted predominantly of Scholte-wave microseism energy. The noise incidence directions have an almost uniform distribution over the azimuth, enabling the synthesis of nearly symmetric estimated Green’s functions between all stations in the array that formed virtual seismic sources. These sources were dominated by Scholte waves traveling along the seafloor, and we sought to determine which features in the subsurface can be imaged by straight-ray group-velocity tomography. We located a high-velocity anomaly in the center of Ekofisk’s production-induced subsidence bowl, surrounded by lower velocities. This pattern seemed to result from production-induced seafloor subsidence that altered the near-surface shear strengths. A dispersion analysis showed that the Scholte-wave virtual seismic source exhibited an approximate penetration depth to 600 m below the seafloor. These results are significant because they demonstrated that recordings made at the ocean-bottom cable array at Ekofisk field in the absence of seismic shooting can be used to image and monitor the near surface.
Ground-penetrating radar profiles of the McMurdo Shear Zone, Antarctica, acquired with an unmanned rover: Interpretation of crevasses, fractures, and folds within firn and marine ice

Published: September 2015

The crevassed firn of the McMurdo shear zone (SZ) within the Ross Ice Shelf may also contain crevasses deep within its meteoric and marine ice, but the surface crevassing prevents ordinary vehicle access to investigate its structure geophysically. We used a lightweight robotic vehicle to tow 200- and 400-MHz ground-penetrating radar antennas simultaneously along 100 parallel transects over a [Formula: see text] grid spanning the SZ width. Transects were generally orthogonal to the ice flow. Total firn and meteoric ice thickness was approximately 160 m. Firn crevasses profiled at 400 MHz were up to 16 m wide, under snow bridges up to 10 m thick, and with strikes near 35°–40° to the transect direction. From the top down, 200-MHz profiles revealed firn diffractions originating to a depth of approximately 40 m, no discernible structure within the meteoric ice, a discontinuous transitional horizon, and at least 20 m of stratified marine ice; 28–31 m of freeboard found more marine ice exists. Based on 10 consecutive transects covering approximately [Formula: see text], we preliminarily interpreted the transitional horizon to be a thin saline layer, and marine ice hyperbolic diffractions and reflections to be responses to localized fractures, and crevasses filled with unstratified marine ice, all at strikes from 27° to 50°. We preliminarily interpreted off-nadir, marine ice horizons to be responses to linear and folded faults, similar to some in firn. The coinciding and synchronously folded areas of fractured firn and marine ice suggested that the visibly unstructured meteoric ice beneath our grid was also fractured, but either never crevassed, crevassed and sutured without marine ice inclusions, or that any ice containing crevasses might have eroded before marine ice accretion. We will test these interpretations with analysis of all transects and by extending our grid and increasing our depth ranges.
The ARF2–ANT–COR15A gene cascade regulates ABA-signaling-mediated resistance of large seeds to drought in Arabidopsis
Authors: Meng Lai-Sheng , Wang Zhi-Bo , Yao Shun-Qiao , Liu Aizhong 
Published: September 2015

ABSTRACT
Seedlings of large-seeded plants are considered to be able to withstand abiotic stresses efficiently. The molecular mechanisms that underlie the involved signaling crosstalk between the large-seeded trait and abiotic tolerance are, however, largely unknown. Here, we demonstrate the molecular link that integrates plant abscisic acid (ABA) responses to drought stress into the regulation of seed mass. Both loss-of-function mutants of the Auxin Response Factor 2 (ARF2 encoding a transcription factor) and lines overexpressing AINTEGUMENTA (ANT; a transcription factor) under the 35S promoter exhibited large seed and drought-tolerant phenotypes as a result of abnormal ABA–auxin crosstalk signaling pathways in Arabidopsis. The target gene COLD-REGULATED15A (COR15a) was identified as participating in the regulation of seed development with ABA signaling through a negative regulation mechanism that is mediated by ANT. The molecular and genetic evidence presented indicate that ARF2, ANT and COR15A form an ABA-mediated signaling pathway to link modulation of seed mass with drought tolerance. These observations indicate that the ARF2 transcription factor serves as a molecular link that integrates plant ABA responses to drought stress into the regulation of seed mass.
Children and adults minimise activated muscle volume by selecting gait parameters that balance gross mechanical power and work demands
Authors: Hubel Tatjana Y. , Usherwood James R. 
Published: September 2015

ABSTRACT
Terrestrial locomotion on legs is energetically expensive. Compared with cycling, or with locomotion in swimming or flying animals, walking and running are highly uneconomical. Legged gaits that minimise mechanical work have previously been identified and broadly match walking and running at appropriate speeds. Furthermore, the ‘cost of muscle force’ approaches are effective in relating locomotion kinetics to metabolic cost. However, few accounts have been made for why animals deviate from either work-minimising or muscle-force-minimising strategies. Also, there is no current mechanistic account for the scaling of locomotion kinetics with animal size and speed. Here, we report measurements of ground reaction forces in walking children and adult humans, and their stance durations during running. We find that many aspects of gait kinetics and kinematics scale with speed and size in a manner that is consistent with minimising muscle activation required for the more demanding between mechanical work and power: spreading the duration of muscle action reduces activation requirements for power, at the cost of greater work demands. Mechanical work is relatively more demanding for larger bipeds – adult humans – accounting for their symmetrical M-shaped vertical force traces in walking, and relatively brief stance durations in running compared with smaller bipeds – children. The gaits of small children, and the greater deviation of their mechanics from work-minimising strategies, may be understood as appropriate for their scale, not merely as immature, incompletely developed and energetically sub-optimal versions of adult gaits.
Agriculture Cooperatives in Lithuania: development issues

Published: September 2015

The evolution of cooperation in Lithuanian agriculture during the past century is analysed in the paper. It was found that cooperation has greatly depended on farming conditions, traditions of communication, state policy with respect to the development of agriculture and cooperation, and various economic conditions. Particularly significant are the specific features of development during transition of economic conditions: weak agricultural structures (farmer’s farms, agricultural companies); the domination of share capital in the processing industry and commerce, and the insufficiency of agricultural and foodstuffs markets.
The basis of analysis in this paper are the theoretical preconditions for the principles of development of the activity of cooperatives. It was determined that most prospective preconditions for development of cooperation at present and in the near future emphasize the comparitive weight of the cost of production of raw materials, i.e. cooperatives of facilities, realisation, finance and representation of interests.
Active Transient Sound Radiation Control from a Smart Piezocomposite Hollow Cylinder
Authors: Hasheminejad Seyyed M. , Rabbani Vahid 
Published: September 2015

Abstract
The linear 3D piezoelasticity theory along with active damping control (ADC) strategy are applied for non-stationary vibroacoustic response suppression of a doubly fluid-loaded functionally graded piezolaminated (FGPM) composite hollow cylinder of infinite length under general time-varying excitations. The control gain parameters are identified and tuned using Genetic Algorithm (GA) with a multi-objective performance index that constrains the key elasto-acoustic system parameters and control voltage. The uncontrolled and controlled time response histories due to a pair of equal and opposite impulsive external point loads are calculated by means of Durbin’s numerical inverse Laplace transform algorithm. Numerical simulations demonstrate the superior (good) performance of the GA-optimized distributed active damping control system in effective attenuation of sound pressure transients radiated into the internal (external) acoustic space for two basic control configurations. Also, some interesting features of the transient fluid-structure interaction control problem are illustrated via proper 2D time domain images and animations of the 3D sound field. Limiting cases are considered and accuracy of the formulation is established with the aid of a commercial finite element package as well as comparisons with the current literature.

Abstract
We have compared historical changes in concentrations of the heavy metals Mn, Ni, Cu, Zn, Cd and Pb accumulated in samples from the Polish woodlands of Beskidy and Karkonosze (S, SE Poland) and the north-east regions of the country, versus the relatively little polluted areas of Spitsbergen of the Svalbard Archipelago. We have combined the results from literature with new results from 2014. The regions of Beskidy and Karkonosze were the most exposed to heavy metals deposition. However, from 1975 to 2014 there was a considerable decrease of concentrations of Cu, Zn, Cd and Pb at all Polish sites, clearly signifying improvement of environmental quality. For example, the average Cd concentration in mosses samples collected in Karkonosze decreased from 0.002 mg/g in 1975 to 0.0006 mg/g in 2014. It is interesting to observe relatively large concentrations of nickel in moss samples collected in 2014 in the Svalbard archipelago, in the vicinity of Longyearbyen (average 0.018 mg/g) which most likely originate from local mine waste piles.

AbstractToday we are living in a globalized world in which information on what is happening in one part of the world is easily communicated to other parts of the world. This happens thanks to advancement in science and technology. One area where technology has made the greatest impact is heath care provision. Ultrasound technology is now playing a critical role in health care provision particularly in Obstetrics and Gynaecology. This has significantly assisted in provision of quality health care to pregnant women and their unborn infants and in reducing maternal and neonatal morbidity and mortality in the developed world. Africa the continent with greatest health care challenges and with the highest maternal and neonatal mortalities is yet to fully utilize this important technology. The need for this technology is great as the conditions requiring its application abound. The effective application of Ultrasound however faces serious challenges in Africa. To successfully entrench Ultrasound in quality Obstetrics and Gynaecology care various approaches must be adopted to overcome the challenges. The aim of this paper is to identify the benefits and the challenges inimical to the application Ultrasound in Obstetrics and Gynecology in Africa. It also examines what needs to be done to achieve better application of Ultrasound in Obstetrics and Gynecology.

Published: September 2015

Abstract
This paper analyses the effectiveness of determining gas concentrations by using a prototype WO3 resistive gas sensor together with fluctuation enhanced sensing. We have earlier demonstrated that this method can determine the composition of a gas mixture by using only a single sensor. In the present study, we apply Least-Squares Support-Vector-Machine-based (LS-SVM-based) nonlinear regression to determine the gas concentration of each constituent in a mixture. We confirmed that the accuracy of the estimated gas concentration could be significantly improved by applying temperature change and ultraviolet irradiation of the WO3 layer. Fluctuation-enhanced sensing allowed us to predict the concentration of both component gases.
Changing arenas of underage adolescent binge drinking in Swedish small towns
Authors: Ander Birgitta , Abrahamsson Agneta , Gerdner Arne 
Published: September 2015

Aim The study explores arenas of adolescent binge drinking in small Swedish towns and the meanings these have for young persons. The focus is thus on space and place, and on the geography of underage drinking. Design An ethnographic approach was used, including direct observations, document studies and contacts with youth workers on local and national levels, and interviews with 28 underage binge-drinking adolescents chosen as informants. Findings Adolescent binge drinkers seem to have moved away from street and other outdoor drinking arenas to home environments, where they feel they have more control over their party location and participants. Conclusions One consequence of outdoor drinking moving indoors is that professional youth workers and police cannot enter party arenas and the only adults who can do so are the parents. This has implications for preventive alcohol strategies and outreach social work. Measures should be directed to parents to make them fully aware of the importance of the party location in their homes.
Thomas Aquinas and Alfred North Whitehead on God‘s Action in the World
Authors: Hosinski Thomas E. 
Published: September 2015

AbstractThomas Aquinas’ intentions in his position that God acts through secondary causes are both laudable and correct. In affirming God’s action within secondary causes Thomas intended to affirm true freedom and contingency in the world and the creatures’ limited participation in God’s creative power. But his interpretation of these topics rests on assumptions about divinity that subvert his intentions. This article summarizes Thomas’ analysis and discusses the principal difficulties with his interpretation of God’s action. It then presents an interpretation of how Alfred North Whitehead’s position on divine action avoids these difficulties and achieves a more coherent understanding of God’s action in the world, even though it too requires revision. If Whitehead’s metaphysics is revised to think of creativity as the divine life rather than as ultimately distinct from God, then it, too, presents God as sharing the divine life with creatures by endowing them with the creativity and freedom to create themselves on the divinely-given ground of possibility. Thomas’ intentions and a revised Whiteheadian interpretation of divine action are compatible and complement each other on the topic of divine action in and through creatures and on the idea of existence as participation in the divine life.

Published: September 2015

Abstract
Sweet sorghum juice and traditional ethanol substrate i.e. sugarcane molasses were used for ethanol production in this work. At the end of the fermentation process, the sweet sorghum juice yielded more ethanol with higher ethanol concentration compared to sugarcane molasses in all experiments. The sweet sorghum juice had higher cell viability at high ethanol concentrations and minimum sugar concentration at the end of the fermentation process. The ethanol concentration and yield were 8.9% w/v and 0.45 g/g for sweet sorghum in 80 h and 6.5% w/v and 0.37 g/g for sugarcane molasses in 60 h, respectively. The findings on the physical properties of sweet sorghum juice revealed that it has better physical properties compared to sugarcane molasses, resulting to enhanced performance of sweet sorghum juice for ethanol production
Use of biogas biscuit meal EKPO-EB for agricultural biogas plant for substitution of energy crops utilization with organic waste
Authors: Chamrádová Kateřina , Rusín Jiří 
Published: September 2015

Abstract
A laboratory experiment of two-stage mesophilic, low-dry mass, anaerobic digestion was carried out, focused on verifying the benefit of processing the biscuit meal EKPO-EB instead of triticale silage Agostino (GPS) and corn silage LG3266 in a regular batch for the agricultural biogas station in Pustějov. While anaerobic digestion of ensilages is largely difficult due to the content of lignocellulose, biscuit meal provides a high yield of biogas or methane, respectively, thanks to its high content of simple saccharides and lipids. When the original GPS (or the replacement EKPO-EB, respectively) represented 0.81% of weight of the daily input mixture dose for the first stage, the rise in volumetric methane production was 20% which is significant. The biscuit meal EKPO-EB decomposes almost completely in the first stage. Later, when the EKPO-EB represented 1.63% of weight of the daily input mixture dose for the first stage, the rise in volumetric methane production was 54% in the first stage and 16% in the second stage.

Abstract
This study proposes a method for the production of ethanol from wheat straw lignocellulose where the raw material is chemically processed before hydrolysis and fermentation. The usefulness of wheat straw delignification was evaluated with the use of a 4:1 mixture of 95% ethanol and 65% HNO3 (V). Chemically processed lignocellulose was subjected to enzymatic hydrolysis to produce reducing sugars, which were converted to ethanol in the process of alcoholic fermentation. Chemical processing damages the molecular structure of wheat straw, thus improving ethanol yield. The removal of lignin from straw improves fermentation by eliminating lignin’s negative influence on the growth and viability of yeast cells. Straw pretreatment facilitates enzymatic hydrolysis by increasing the content of reducing sugars and ethanol per g in comparison with untreated wheat straw.
