Authors: Matthaus Bertrand , Özcan Mehmet Musa 
Published: June 2014

Abstract

Background
The aim of current study is to establish the composition of these seeds belong to Rosaceae family with respect to fatty acid, tocopherol and squalene content.

Results
The oil contents of seeds varied between 3.49 (Cotoneaster bullatus) to 46.15 g/100 g (Prunus tenella). The main fatty acids of seed oils were oleic (6.50 - 67.11 %), linoleic (22.08 - 68.62 %) and 20:1n-7 (0.10 - 61.59 %). As observed, the oils of seed were rich in linoleic and oleic acids. Total tocopherol contents ranged between 7.06 mg/100 g (Prunus tenella) to 165.74 mg/100 g (Potentilla glandulosa ssp. pseudorupestris). The major tocopherols were γ-tocopherol, ranging from 2.08 mg/100 g to 106.01 mg/100 g; α-tocopherol ranging from 2.86 mg100 g to 74.26 mg/100 g and δ-tocopherol ranging used in this experiment were found between 0.02 mg/100 g (Alchemilla caucasica) to o.29 mg/100 g (Cotoneaster simonsii).

Conclusions
These results show that Rosaceae seed oils can be a potential saurce of valuable oil which might be useful for the evaluation of dietary information in important food crops and other industrial applications.

Abstract
Pancreatic adenocarcinoma, one of the worst malignancies of exocrine pancreas, is a solid tumor with increasing incidence and mortality in industrialized countries. It is usually driven by oncogenic Kras point mutations and evolves into a highly aggressive metastatic carcinoma due to secondary gene mutations and specific signaling pathways unbalance. To examine in vivo the effects of KrasG12D during pancreatic cancer progression and time correlation with cancer signaling pathways activities, we have generated a zebrafish model of Pancreatic adenocarcinoma in which eGFP-KrasG12D expression was specifically driven to the pancreatic tissue by using the GAL4/UAS conditional expression system. Outcrossing the inducible oncogenic KrasG12D line with transgenic zebrafish reporters harboring specific signaling responsive elements of transcriptional effectors, we were able to follow TGFβ, Notch, Bmp and Shh activities during tumor development. Zebrafish transgenic lines expressing eGFP-KrasG12D showed normal exocrine pancreas development till 3 weeks post fertilization (wpf). From 4 to 24 wpf we observed several degree of acinar lesions, characterized by an increase of mesenchymal cells and mixed acinar/ductal features followed by progressive bowel and liver infiltrations finally bringing to highly aggressive carcinoma. Moreover, live imaging analysis of the exocrine pancreatic tissue revealed an increasing number of Kras positive cells and progressive activation of TGFβ; and Notch pathways. Increase of TGFβ, following KrasG12D activation, was confirmed in a concomitant model of medulloblastoma (MDB). Notch and Shh signaling activities during tumor onset were different between MDB and pancreatic adenocarcinoma indicating a tissue specific regulation of cell signaling pathways. Moreover, our results shows that a living model of pancreatic adenocarcinoma joined with cell signaling reporters is a suitable tool to describe in vivo the signaling cascades and molecular mechanisms involved in tumor development and a potential platform to screen for novel oncostatic drugs.

Published: June 2014

Abstract
In the presence of molecular oxygen and zeolite H-β with Si/Al2 = 500, o-xylene reacted regioselectively with liquid nitrogen dioxide at 35 °C to yield mononitro-o-xylenes as the main product, where the 4-nitro-o-xylene isomer predominated up to 89% and the 4-nitro-/3-nitro-o-xylene isomer ratio improved to 7.8. The process is eco-friendly, less expensive, and the zeolite could be easily regenerated by a simple workup to afford results similar to those obtained with the fresh catalyst.

Published: June 2014

Abstract
Sulfur-containing species, such as sulfite, are detrimental to the operation of anaerobic systems, therefore, it is critical to determine their concentrations in order to optimize an anaerobic reactor. In this study, the traditional titration method for the determination of sulfite was applied to acid-condensate samples from an acid sulfite pulp mill effluent, and the results showed that they were consistently lower than those from ion chromatography (IC). It was found that the presence of furfural in the acid-condensate samples can interfere with the titration for sulfite, resulting in lower sulfite values; the higher the furfural concentration in the sample, the lower the indicated sulfite concentration by titration. It was concluded that IC method is a reliable method for determining the sulfite concentration for samples containing furfural.
Steady State Modeling and ANFIS Based Analysis of Self-Excited Induction Generator
Authors: Enany Mohamed A. 
Published: May 2014

Self-excited induction generator (SEIG) has the ability to generate power at varying speed, which facilitates its application for wind energy conversion in remote and windy areas. Estimation of the generator behavior under actual operating conditions is essential, but the SEIG analysis with conventional techniques take long time with fatigued mathematical procedures. This paper presents a new technique for the performance analysis of a three phase SEIG supplying an isolated resistive load using adaptive neuro-fuzzy inference system (ANFIS). Proposed ANFIS model has been implemented to predict the effect of prime mover speed, capacitance and load on generated voltage of SEIG. Experimental data is used for the training of ANFIS. Results obtained from the trained have been compared with the experimental results. The comparison confirms the validity and accuracy of the ANFIS based modeling of induction generator.

Published: June 2014

ParkPGH is a novel parking application that provides real-time and predictive information on the availability of garage parking spaces within Pittsburgh’s Cultural District. The core of the application is a module that collects real-time parking information from the garages by tapping into their gate counts. The real-time component is complemented by a module that uses historical data and an events calendar to predict parking availability. In 2011, visitors to downtown Pittsburgh used ParkPGH more than 300,000 times to determine when and where to park. The application has also been beneficial to garage operators because the information it provides on parking demand affords them greater flexibility in addressing contingencies and managing lease holders. The deployment of ParkPGH, which includes a robust evaluation component, is one piece of a broader transportation ecosystem within the Greater Pittsburgh region. The lessons we learned from the initiative, the application’s relatively low cost, its ease of retrofitting, and its open-source platform can enable other cities to lower the costs of implementing and managing similar smart-parking solutions and significantly shorten their learning curves.
Do Temporary Increases in Information Asymmetry Affect the Cost of Equity?
Authors: Levi Shai , Zhang Xiao-Jun 
Published: June 2014

Prior literature finds that long-lasting changes in firms' disclosure policies and information environment affect the cost of equity. Information asymmetry, however, also changes during the fiscal quarter. Firms disclose information periodically, and in between disclosure dates, traders can obtain private information, and adverse-selection risk increases. Such temporary increases in information asymmetry are usually considered to be diversifiable or too small to impact expected stock returns. In addition, investors may postpone trades or sell other assets in their portfolio on high information asymmetry days. We, however, find that returns increase significantly on days during the fiscal quarter when adverse-selection risk is high and liquidity low. Consistent with theory, we show that temporary asymmetry affects returns when investors demand liquidity and market makers bear risk for carrying capacity and providing it.

Cognitive grounding for cross-cultural commercial communication
Authors: Pérez Hernández Lorena 
Published: June 2014

AbstractInternationally recognized brands are an increasingly essential asset for present-day companies. This paper takes a cognitive perspective on the semantics of commercial brands (and their related logos), and explores the role of image schemas in endowing them with a cross-culturally significant core meaning. Two surveys were carried out among speakers of four different languages (i.e., English, Spanish, Chinese, and Arabic) in relation to the logos of several car categories (minis, family cars, 4 × 4s, and sports cars) and a limited set of image schemas (CONTAINER, FORCE, and ATTRIBUTE). The analysis of the results reveals a consistent correlation between the participants' semantic interpretation of the car brands, and the basic meanings deriving from the image schemas included in their logos. The outcome of the surveys also points to the existence of potential constraints on the universal reach of image-schematic-based communication. These limitations emerge either from the combination of image schemas with additional idealized cultural models, or from the use of specific richer configurations of the image-schematic visual cues at work. In this connection, the present study explores the inventory of visual configurations available for the representation of the image schemas under scrutiny, assesses their universal significance, and raises awareness about differences in the cross-cultural communicative effectiveness of the various layouts of a given image-schematic cue.

Background & Aims: Autoimmune pancreatitis (AIP) is a fibroinflammatory condition affecting the pancreas and could present as a multisystem disorder. Diagnosis and management can pose a diagnostic challenge in certain groups of patients. We report our experience of managing this condition in a tertiary pancreaticobiliary centre in the North East of England.Methods: Patients were identified from a prospectively maintained database of patients diagnosed with AIP between 2005 and 2013. Diagnosis of definite/probable AIP was based on the revised HISORt criteria. When indicated, patients were treated with steroids and relapses were treated with azathioprine. All patients have been followed up to date.Results: Twenty-two patients were diagnosed with AIP during this period. All patients had pancreatic protocol CT performed while some patients had either MR or EUS as part of the work up. Fourteen out of 22 (64%) had an elevated IgG4 level (mean: 10.9 g/L; range 3.4 - 31 g/L). Four (18%) patients underwent surgery. Extrapancreatic involvement was seen in 15 (68%) patients, with biliary involvement being the commonest. Nineteen (86%) were treated with steroids and five (23%) required further immunosuppression for treatment of relapses. The mean follow up period was 36.94 months (range 7 - 94).Conclusion: Autoimmune pancreatitis is being increasingly recognized in the British population. Extrapancreatic involvement, particularly extrahepatic biliary involvement seems to be a frequent feature.Diagnosis should be based on accepted criteria as this significantly reduces the chances of overlooking malignancy. Awareness of this relatively rare condition and a multi-disciplinary team approach will help us to diagnose and treat this condition more efiectively thereby reducing unnecessary interventions.

Islam as a religion is to be critical of religion two predecessors, both to Jews and Christians. However, according to NU, the Islamic view of Christianity is more positive than the views about Jews. That's because the Jewish religion is seen in relationship with God has strayed too far. A positive attitude of Islam towards Christianity, according to NU, can be seen in the statement of the Koran that praises that among Christians there are monks and priests who are not arrogant. But NU deplore the ways and practices of Christianization in Indonesia are judged contrary to the positive attitude of Islam towards ChristianityDOI: 10.15408/sdi.v4i3.774
Targeting of a magnetic bionanomaterial to HepG2 human hepatocellular carcinoma cells using a galactose terminated lipid
Authors: Booth Andrew , Coxon Thomas P. , Gough Julie E. , Webb Simon J. 
Published: June 2014

ABSTRACTMagnetic nanoparticle-vesicle aggregates (MNPVs), a controlled release nanostructure, have been enhanced with the inclusion of a novel galactose terminated lipid for cell targeting. Quartz crystal microgravimetry with dissipation (QCM-D) demonstrated that the galactose headgroup was available to bindErythrina Crista-gallilectin (ECL) when the lipid was incorporated into a lipid bilayer. Similarly, UV-visible spectrophotometry indicated that ECL recognized the galactose headgroup in vesicles, leading to vesicle adhesion and aggregation. Finally, confocal fluorescence microscopy was used to assess the galactose-mediated interaction of both vesicles and MNPVs with HepG2 human hepatocellular carcinoma cells expressing the asialoglycoprotein (ASGPR) galactose receptor.
Magneto-optic Response of Functionalized vs. Uncoated Fe2O3 (Maghemite) Nanoparticles

Published: June 2014

ABSTRACTIron oxide nanoparticles (NPs) have attracted a lot of interest due to their many potential applications in areas including optoelectronics, magneto-optics, high density data storage, etc. In particular, iron oxides (Fe3O4 and γ –Fe2O3) are also well suited for biomedical applications [1]. We have investigated Faraday Rotation (FR) response for two types of Fe2O3 NPs (in aqueous suspension) that are of the same average diameter (10 nm) but differ in one important respect; one group consists of uncoated particles whereas the other group is functionalized with caffeic acid. This system is being investigated and characterized for use in tumor imaging applications. Faraday rotation (FR) refers to the rotation of the polarization vector of a light beam as it passes through a sample in the presence of a magnetic field. FR can reveal interesting material properties such as saturation magnetization and wavelength dependent Verdet constant of the material under investigation. The latter is a measure of the magnetically induced birefringence of the material. Typically FR setups rely on AC or DC magnetic fields. While these are valuable techniques with their own advantages, this work focuses on a pulsed field setup that can reveal dynamic information about the resulting magnetization, as the magnetic response of the sample is measured in the presence of short intense fields on the order of 0.6 Tesla and lasting approximately 100 milliseconds. All experiments are carried out at excitation wavelength of 633 nm (He-Ne wavelength).The two NP samples show very different response to the field pulses. The NP systems investigated in this work show very unique short term and long term behavior revealing various time scales of interest. These unique characteristic times for the functionalized vs. uncoated particles provide valuable clues about the magnetization response of the NP and its relationship to the detailed structure of the NPs (core vs. shell). Magnetic response from these systems persists long after the magnetic field pulse has subsided. This can be related to the relaxation modes (Néel vs. Brownian) and as possible evidence of NP size dispersion. Additionally, the possibility of agglomeration is also discussed. While more detailed quantitative analysis will be dealt with in a more comprehensive publication that is under preparation, we hope to show in this preliminary report both that the AC and pulsed FR measurements can reveal complimentary information and that FR in general can be a reliable technique, which can be used to develop a detailed picture of the magnetic response of these NP systems.

Published: June 2014

ABSTRACT3D scaffolds with different pore sizes, using single-walled carbon nanotubes (SWCNTs) and nanoparticles of different size were constructed. Biotinylated glucose oxidase (GOX-B) and anti-cholera toxin (anti-CT) were immobilized onto the one and two level nanoscaffolds, functionalized with pyrene-β-cyclodextrin for the construction of glucose based enzyme sensors and immunosensors, respectively. For enzyme sensors, highest current density and sensitivity (41.72 μA cm-2, 3 mA M-1 cm-2) were obtained with two level scaffolds made with 100 nm nanoparticles. In contrast to this, for immunosensors, highest current density and sensitivity (11.71 μA cm-2, 116.2 μA M-1 cm-2) were obtained with two level scaffolds made with 500 nm nanoparticles, indicating that the pore sizes can be adjusted using different size of nanoparticles for the respective applications.

Abstract
Reentry drilling operations have been one of the most popular means for field development over the past decade. Many of the wells in mature fields tend to suffer from low productivity which would require reentry operations to increase reservoir contact and extend the life of the well. This has been preferable, in many cases, to drilling a completely new well from surface with all the associated costs and risks present in crowded old fields.
Reentry drilling operations would normally require slimming down of the well design or the use of newly introduced expandable technologies to maintain similar hole sizes. The use of expandable technologies requires hole enlargement before running the liner. Running and expanding a liner string requires a smooth wellbore with minimal doglegs and tortuosity. A bad quality wellbore will lead to challenges that may result in not being able to run the expandable string to bottom, getting stuck or not fully expanding the liner. Past experiences have shown that utilizing a conventional motor and bent sub assembly to drill the 6 1/8-in. hole, and then run a 7-in. or 7 3/8-in. hole opening assembly has proven to be time consuming and may require under-reaming the same section more than once. The result is a borehole with an inconstant hole diameter, excessive doglegs and high tortuosity due to shifting between sliding and rotary mode. This phenomenon is significantly reduced when using a rotary steerable system (RSS) due to the continuous rotation of the string during directional drilling.
In an effort to optimize the reentry operations, Saudi Aramco and the service company utilized a highly sophisticated drilling assembly combining hole-opening technology, high-build-rate RSS and measurements-/logging-while-drilling (MWD/LWD) tools. This was the first time such an assembly has been utilized for this particular application worldwide. The goal was to sidetrack, drill, and enlarge the section in one run, producing a well geometry suitable for landing and expanding the solid expandable tubular. The first application drilled and underreamed the 6 1/8-in. × 7 3/8-in. hole from the kick off point to total depth using Schlumberger's high-dogleg RSS system. As a result, the 5 1/2-in. expandable liner was run to bottom, cemented, and expanded successfully.
So far, this system has been successfully run twice in Saudi Aramco reentry operations. In both cases, utilizing the combined drilling system has proven to improve wellbore quality and reduce the well delivery time by an average of 4 operating days.
