ANTIOXIDANT AND ANTIRADICAL ACTIVITIES OF ROSA CANINA AND ROSA PIMPINELLIFOLIA FRUITS FROM WEST AZERBAIJAN

Rosa canina L. is a member of Rosaceae family, which is well-known for its high phenolic contents. These compounds are known to possess antioxidant and antiradical effects. In order to compare the antioxidant and antiradical activity of wild Rosa phenolic extracts, two wild Rosa species (Rosa canina L. and Rosa pimpinellifolia L.) were selected from Takab, Oshnavieh and Qasemloo Valley of Urmia, West Azerbaijan province, Iran, in 2011. The fruits of R. canina and R. pimpinellifolia were collected and then methanolic extracts were prepared from these fruits. The extracts' total phenolic and flavonoid contents and scavenging capacity for radicals nitric oxide, hydrogen peroxide, and DPPH were analyzed. Fruit extracts, respectively, had a range of 176.48 ± 2.71 and 225.65 ± 2.50 mg gallic acid equivalents /100 g methanolic extract in total phenolic content, 0.41± 0.02 and 2.02 ± 0.03 mg quercetin/100 g methanolic extract in total flavonoid content, 22.41 ± 0.64% and 58.10 ± 0.72% in hydrogen peroxide, 79.16 ± 0.61% and 87.78 ± 0.10% in DPPH, and 76.93 ± 2.31% and 236.76 ± 16.04% in nitric oxide radical scavenging percentage. The findings suggested that radical scavenging capacities of R. canina and R. pimpinellifola extracts in different populations positively correlated with phenolic content.

Biometrical Features of Intergeneric Hybrid between Leuciscus cephalus (L.) and Chalcalburnus chalcoides (G.) (Osteichthyes-Cyprinidae) Distributed in Lake Tödürge (Sivas-Turkey)

A total of 159 (57 Leuciscus cephalus, 47 Chalcalburnus chalcoides, 55 hybrid) specimens were collected between April 1994 and November 1997 from Lake Todurge. The identification of hybrid fishes depends on the intermediacy of the suspected hybrid specimens in characteristics that serve to discriminate the parental species. For this reason, the morphometric and meristic characteristics which present an intermediate position in the hybrid were determined. Among the morphometric (X7: standard length/height of caudal peduncle, X19: standard length/length of anal fin, X21: standard length/length of pectoral fin, X24: standard length/ventral anal distance, X38: length of upper jaw/length of lower jaw) and meristic (X41: count of soft rays in anal, X43: count of soft rays in ventral, X49: transversal scales (upper part), X51: pharyngeal teeth) characteristics were the most effective characteristics in discrimination of both parental species and the hybrids. Two linear discriminant functions that explain 100% of the total variability of the morphometric and meristic features of hybrid and both its parents were obtained. On the basis of statistical analysis, an intergeneric hybridization was determined to occur between chub (L. cephalus) and Danube bleak (C. chalcoides) in Lake Todurge (Sivas-Turkey), and chub and Danube bleak were really the parental species of this hybrid. Statistical analyses were also showed that, there was no back-crossing with one of the parental species and therefore all hybrids were F1.
Treatment of Sago Wastewater using Hybrid Anaerobic Reactor

Sago, tapioca starch, is manufactured by over 800 small-scale units located in the Salem district of the State of Tamilnadu, South India. These units generate large quantities of high-strength wastewater requiring elaborate treatment prior to disposal. The present study is an attempt to treat the sago wastewater using a hybrid reactor, which combines the advantages of both fixed-film and up-flow anaerobic sludge blanket systems. A hybrid reactor with a volume of 5.9 L was operated at organic loading rates varying from 10.4 to 24.6 kg COD/m 3 d. After 120 d of start-up, an appreciable decrease in COD and efficient removal of solids were evident. The COD removal varied from 91 to 83%. While the removal of total solids was in the range of 56 to 63%, that of volatile solids varied from 67 to 72%. The methane production during the study period was in the range of 0.11 to 0.14 L CH4/g COD-d and the percentage was from 55 to 67%. The ideal organic loading rate (OLR) was determined on the basis of tolerance of the reactor towards higher organic loading rate and it was found to be 23.4 kg COD/m 3 d. The findings of the study open new possibilities for the design of low-cost and compact on-site treatment systems
Trust of high school students in Wikipedia

Wikipedia is an open encyclopedia: Nearly everyone can edit most of its content. Having been a key element for Wikipedia’s striking success, the open character poses a challenge to its users: How can they form an opinion about whether to trust the information? Lucassen and Schraagen (2010) have made an approach to define the criteria that are used by academic students to evaluate the trustworthiness of Wikipedia articles. This is a follow-up study to further qualify the findings of Lucassen and Schraagen with another population, namely high school students. In an experimental setting, Familiarity and Quality of the articles are manipulated. We show that high school students employ different features than academic students to assess the trustworthiness of Wikipedia articles. The most frequently used features were textual features and pictures. It is concluded that when evaluating trustworthiness of Wikipedia articles, high school students mostly rely on comparison with their own knowledge.
Improved Krill Herd Algorithm with Neighborhood Distance Concept for Optimization

Krill herd algorithm (KHA) is a novel nature inspired (NI) optimization technique that mimics the herding behavior of krill, which is a kind of fish found in nature. The mathematical model of KHA is based on three phenomena observed in the behavior of a herd of krills, which are, moment induced by other krill, fo raging motion and random physical d iffusion. These three key features of the algorithm provide a good balance between global and local search capability, which makes the algorithm very powerfu l. The objective is to minimize the distance of each krill from the food source and also from the point of highest density of the herd, which helps in convergence of population around the food source. Improvisation has been made by introducing neighborhood distance concept along with genetic reproduction mechanism in basic KH Algorithm. KHA with mutation and crossover is called as (KHAMC) and KHA with neighborhood distance concept is referred here as (KHAMCD). This paper compares the performance of the KHA with its two improved variants KHAMC and KHAMCD. The performance of the three algorithms is compared on eight benchmark functions and also on two real world economic load dispatch (ELD) problems of power system. Results are also compared with recently reported methods to establish robustness, validity and superiority of the KHA and its variant algorithms.
Role of potentials in the Aharonov-Bohm effect

There is a consensus today that the the main lesson of the Aharonov-Bohm effect is that a picture of electromagnetism based on the local action of the field strengths is not possible in quantum mechanics. Contrary to this statement it is argued here that when the source of the electromagnetic potential is treated in the framework of quantum theory, the Aharonov-Bohm effect can be explained without the notion of potentials. It is explained by local action of the field of the electron on the source of the potential. The core of the Aharonov-Bohm effect is the same as the core of quantum entanglement: the quantum wave function describes all systems together.
Effect of Nitric Oxide on Postharvest Quality and Vase Life of Cut Carnation Flower

Nitric oxide (NO) is a highly reactive signaling molecule and plays a variety of physiological roles in plants. The research on the application of NO to postharvest preservation of flowers and fruits shows great promise in recent years. However, the physiological mechanism of exogenous NO to affect cut flowers is not very clear, and NO donor treatment protected plants from damage by increasing the activity of anti-oxidative enzymes. Therefore, an experiment was conducted to study the effect of exogenous NO on the vase life and physiological basis of Dianthus caryophyllus L. ‘Tempo’. The presence of the nitric oxide increased the activities of POD, while the production of MDA content and LOX activity were obviously decreased. The results showed that exogenous NO could significantly extend the vase life of cut carnation flowers (16.9 days). The results suggest that exogenous NO could delay petal wilting in carination cut flowers, maintain water metabolism, the anti-oxidative enzymes activity and mass-eliminate reactive oxygen species (ROS) and as well as cell membrane stability.
Outlier Detection in Online Gambling

Data mining is field that is increasing in importance and width of application day by day. A sub-domain of data mining, the anomaly detection is also rising in importance the last years. Although discovered a long time ago, the last 5 or 10 years the uses of anomaly detection are increasing, therefore making it a useful technique to discover fraud, network intrusions, medicine side effects and many other useful anomalies within a wide set of data. The task of this master thesis is to find a more optimal anomaly detection technique to uncover fraudulent use or addictive playing in the transaction data of online gambling websites. This work is conducted on behalf of a Swedish company that is occupied in the field of data mining. For the needs of this work an anomaly detection method has been adapted, implemented and tested. The evaluation of this method is done by comparing the results it brings with the anomaly detection technique currently used for the same purpose.
Organic Photovoltaic Cells Based on PbPc Nanocolumns Prepared by Glancing Angle Deposition

Organic small material lead phthalocyanine (PbPc) nanocolumns were prepared via glancing angle deposition (GLAD) on indium tin oxide (ITO) coated glass substrates. Organic electron acceptor materials fullerene (C60) was evaporated onto the nanocolumn PbPc thin films to prepare heterojunction structure ITO/PbPc/C60/Bphen/Al organic photovoltaic cells (OPVs). It is worthwhile to mention that C60 molecules firstly fill the voids between PbPc nanocolumns and then form impact C60 layer. The interpenetrating electron donor/acceptor structure effectively enhances interface between electron donor and electron acceptor, which is beneficial to exciton dissociation. The short circuit current density (Jsc) of organic photovoltaic devices (OPVs) based on PbPc nanocolumn was increased from 1.19 mA/cm2 to 1.74 mA/cm2, which should be attributed to the increase of interface between donor and acceptor. The effect of illumination intensity on the performance of OPVs was investigated by controlling the distance between light source and sample, and the Jsc of two kind of OPVs was increased along with the increase of illumination intensity.
Hospital Income Loss due to Incomplete Clinical Documentation: A Survey of Service Items and Potential Causes in the Iranian Teaching Hospitals

Background and Objectives: Many Iranian public hospitals are faced with serious financial challenges such as shortage of income and heavy debts. Nevertheless, many of the healthcare services are often remained unearned for not being included in the clinical records or patient bill, resulting in considerable loss of legitimate hospital in‌come. Given the limited studies in this area in Iran, the present study aimed to survey the undocumented healthcare services which are potentially income-generating, and the factors contributing to the deficient documentation. Methods: A cross-sectional retrospective study was conducted. A sample of 400 clinical records was selected from six hospitals affiliated with Shahid Beheshti University of Medical Sciences in proportion to the number of hospital beds and the rate of discharges. A checklist was developed to record the delivered healthcare services, which were incompletely documented or neglected in the patients’ bills. Using a researcher-made questionnaire, we also asked the opinions of financial managers, the income managers, the chief operators, and other personnel of the discharge unit, with regards to the human resources factors influencing clinical documentation and accounting. The tariffs for the health services were calculated based on the corresponding K value, extracted from the Cali‌fornia Book of relative values of diagnostic and therapeutic services. Data were summarized and analyzed using descriptive statistical methods. Findings: NG tube insertion; CVP insertion, lumbar puncture, pleural tap and cut down were the five most frequently neglected medical services in the clinical records. Overall, 998 services for the amount of 75 million Rls were not documented. Only a minority of the personnel of the finance departments had a background of education in accounting. In addition, the majority of financial department personnel had not attended any train‌ing course related to the documentation of healthcare services and discharge process. On average, 20 medical records are examined on a daily basis by a single operator in the pre-discharge stage, ranging from 13 to 25 records. In addition, the employees of the discharge units were found to have the dual task of examining clinical records and discharging the patients. Conclusions: Our study identified a number of potentially income-generating healthcare services that are often left unearned in Iranian hospitals. Identification of these services may help prevention of the associated income loss in future. We also identified a number of factors that may contribute to inaccurate documentation of health‌care services. The importance of issue and the possible existence of other factors contributing to incomplete clinical documentation and hospital income loss recommend further large-scale studies.
Upper Tithonian Ammonites and Floras from the Chicama Basin, Northern Peruvian Andes

The 3000 meters-thick Chicama Group is the infilling of a basin which was opened during late Tithonian time in the western platform of Northern Peru. The lithology and sedimentology express the evolution from slope apron to slope deposits (Punta Moreno Formation), then to prodelta or basinal facies (Sapotal Formation), and finally to nearshore and deltaic environments ending with fluvial deposits (Tinajones Formation). Ammonites were found mainly in the upper part of the Punta Moreno and in the Sapotal Formations. Micracanthoceras is steadily present, and is associated with genera known in Tethyan Europe and Mexican-Andean areas (Proniceras. Duranaites, ? Protacanthodiscus), with genera so far unknown in South America (Moravisphinctes, Zittelia) and with classical components of peripacific regions (Parodontoceras). The fauna is ascribed to the Alternans zone of the Andean biochronological standard, which is probably equivalent to the Microcanthum zone of Europe, of early Late Tithonian age. Plants remains occur somewhat higher in the section (Upper Punta Moreno, Sapotal and Tinajones Formations). Bennettitales (Ptilophvllum acutifolium. Otozamites) are dominant, associated with less abundant Caytoniales (Sacenoneris) and Coniferales (Cumessinocladus). This assemblage is similar to the Late Jurassic/Early Cretaceous paleofloras from Gondwanaland.
Effective anisotropic velocity model from surface monitoring of microseismic events

We develop a methodology to obtain a consistent velocity model from calibration shots or microseismicity observed on a buried array. Using a layered 1D isotropic model derived from checkshots as an initial velocity model, we invert P‐wave arrival times to obtain effective anisotropic parameters with a vertical axis of symmetry (VTI). The nonlinear inversion uses iteration between linearized inversion for anisotropic parameters and origin times or depths, which is specific to microseismic monitoring. We apply this technique to multiple microseismic events from several treatments within a buried array. The joint inversion of selected events shows a largely reduced RMS error indicating that we can obtain robust estimates of anisotropic parameters, however we do not show improved source locations. For joint inversion of multiple microseismic events we obtained Thomsen anisotropic parameters ε of 0.15 and δ of 0.05, which are consistent with values observed in active seismic surveys. These values allow us to locate microseismic events from multiple hydraulic fracture treatments separated across thousands of metres with a single velocity model. As a result, we invert the effective anisotropy for the buried array region and are able to provide a more consistent microseismicity mapping for past and future hydraulic fracture stimulations.
Low-fat Wet Distillers Grains and Beef Quality

A low-fat (4.72%) wet distillers grain (LFWDG) diet was compared to a traditional wet distillers grain with solubles (WDGS) diet and a corn-based diet. All wet distillers diets increased polyunsaturated fatty acids in comparison to the control. The LFWDG diet caused greater oxidative rancidity and had a decreased shelf life; however, there was no change in sensory properties. The LFWDG diet evaluated in this study caused decreased oxidative stability of the muscle compared to the TWDGS and the control diets.
Investigating relationships between and within entry pathways on a sport related programme and the degree outcome obtained

Abstract Research within Higher Education in the United Kingdom has reported conflicting findings when investigating the relationship between undergraduate entry routes and gender, with successful performances across the degree cycle. This paper adds to this body of knowledge and examines the relationship between entry routes and gender on student outcomes in a sport related degree at an UK HE institution. Students’ demographic data, entry qualifications and grade point averages (GPAs) across the 3-year degree programme were retrospectively analysed. In relation to entry routes the findings of this study revealed that no significant difference existed between entry level qualifications and all outcomes measures. Indicating that although entry routes into HE may differ this did not impact on student success for those who completed the programme. Further findings revealed significant differences (p < 0.05) between genders, in that females outperformed their male counterparts at levels 5, 6 dissertation and final GPA. Additionally, females were also more likely to achieve a first degree qualification. This study adds further weight to findings which have shown gender differences but in contrast adds to the complexity of predicting successful performances from entry qualifications.
Difiusion Limit for the Vlasov-Maxwell-Fokker-Planck System

In this paper we study the difiusion limit of the Vlasov-Maxwell-Fokker-Planck System. Here, we generalize the one and one half dimensional case, obtained in (5) to the case of several space dimen- sions using global renormalized solutions. The limit equation consists in a Drift-Difiusion equation where the drift velocity is deflned by means of the Maxwell relation.
Advances in Engineering Education Survey Tools for Faculty to Quickly Assess Multidisciplinary Team Dynamics in Capstone Courses

Many engineering faculty have limited skills and/or assessment tools to evaluate team dynamics in multidisciplinary team-based capstone courses. Rapidly deployable tools are needed here to provide proactive feedback to teams to facilitate deeper learning. Two surveys were developed based on industrial and organizational psychology theories around desired high performance industry characteristics. A case study experiment was conducted in an architectural engineering capstone. Here, these surveys were deployed in conjunction with traditional qualitative verbal feedback and technical assessments. Results presented here suggest that capstone teams exhibit high-functioning attributes of effective teams based on the course formulation. Team dynamics evolved as the course progressed naturally and with the help of faculty based on the survey results. Discussions in this paper detail survey development, implementation, and sampled trends to represent how to use and interpret the survey output. Furthermore, best practices for implementing these ideas in other courses is touched on. Evidence is presented to support the surveys as a tool and to show correlations between the results and other technical assignments.
Firm Size and Profitability: A Study of Listed Manufacturing Firms in Sri Lanka

The purpose of this study is to explore the effects of firm size on profitability of quoted manufacturing firms in Sri Lanka. In this study, data of 15 companies which were active in Colombo Stock Exchange (CSE) between the years 2008 to 2012 has been used. As indicators of firm profitability, Return on Assets and Net Profit have been used whereas Total Assets and Total Sales have been utilized as indicators of firm size. Correlation and regression methods have been used in the empirical analysis. There is no indicative relationship between firm size and profitability of listed manufacturing firms, the findings reveal. In addition, the results showed that firm size has no profound impact on profitability of the listed manufacturing firms in Sri Lanka.
AmpC beta-lactamase production among Pseudomonas aeruginosa and Proteus mirabilis isolates at the Komfo Anokye Teaching Hospital , Kumasi , Ghana

Extended spectrum β-lactamases (ESBLs) are frequently reported in Ghana, but AmpC bacteria reports are scanty. This study determines the prevalence of AmpC Pseudomonas aeruginosa and Proteus mirabilis clinical isolates at the Komfo Anokye Teaching Hospital (KATH), Kumasi, where ESBL and AmpC are not routinely tested. Non-duplicate 245 isolates comprising 187 (76.3%) P. aeruginosa and 58 (23.7%) P. mirabilis were tested for AmpC and ESBL production using the modified three-dimensional test method and the double disc synergy test (DDST) methods, respectively. The proportion of the 245 isolates producing AmpC β-lactamase was 93 (38.0%) and 79 (32.2%) produced ESBL. AmpC producers confirmed 49 (52.7%) as inducible and 44 (47.3%) non-inducible AmpC producers. P. aeruginosa and P. mirabilis that produced AmpC were 84 (44.9%) and 9 (15.5%), respectively. ESBL production was 41 (21.9%) in P. aeruginosa and 38 (65.6%) in P. mirabilis. Co-producers of AmpC together with ESBL were 7.3%. Both enzyme were detectable in 13 (7.0%) of P. aeruginosa and 5 (8.6%) of P. mirabilis. AmpC and ESBL are detectable in high proportions among P. aeruginosa and P. mirabilis isolates at KATH and the Kumasi community. This emphasizes the need to start testing for both enzymes to guide therapeutics.
