FePc Adsorption on the Moire Superstructure of Graphene Intercalated with a Cobalt Layer

The moire superstructure of graphene grown on metals can drive the assembly of molecular architectures, such as iron–phthalocyanine (FePc) molecules, allowing for the production of artificial molecular configurations. A detailed analysis of the Gr/Co interaction upon intercalation (including a modeling of the resulting moire pattern) is performed here by density functional theory, which provides an accurate description of the template as a function of the corrugation parameters. The theoretical results are a preliminary step to describe the interaction process of the FePc molecules adsorption on the Gr/Co system. Core level photoemission and absorption spectroscopies have been employed to control the preferential adsorption regions of the FePc on the graphene moire superstructure and the interaction of the central Fe ion with the underlying Co. Our results show that, upon molecular adsorption, the distance of C atoms from the Co template mainly drives the strength of the molecules-substrate interaction, t.
A Search for Alternative Solvent To Hexane During Neem Oil Extraction

The growing environmental concerns on the toxicity and flammability of hexane motivate the need to obtain a more environmentally friendly solvent capable of extracting as much oil as hexane or even more, while giving acceptable oil quality. This study therefore investigated the possibility of replacing Hexane with either Ethanol or the mixtures of both in the extraction of Neem Oil from Neem seed. It was observed that as the extraction time increased, oil yield increased, though there was little or no increase in oil yield at 5hours and 6 hours of operations. At different extraction time, Hexane produced oil yields greater than that obtained from Ethanol. Hence, Ethanol did not prove to be a good replacement for Hexane, even at higher temperature of 75C for Ethanol. Optimum temperature of extraction was found to be 55C. Surprisingly, mixtures of Ethanol and Hexane gave commendable results. Particularly, Ethanol-Hexane mixtures of 60/40, 50/50, and 40/60 % (volume proportions) gave better oil yields of 44%, 43% and 41.2% respectively than that of Hexane (40.25%) at the 6 hours of operation, thereby making the combinations good substitutes for Hexane.

A preliminary study into the potential of mayflies (Ephemeroptera: Baetidae and Caenidae) as bio-indicators of stream health in Fiji

flowing through an area of tropical lowland rainfor est and urban streams running through residential and indus trial areas. The two rural streams were Waisila Stream l ocated within the Colo-I-Suva Forest Reserve approximately 6 km from Suva and the Savura water catchment within the forested area of the upper Wailoku River. The two urban streams were the Nabua stream where it runs through an army barracks and the Nabukalou creek running directly through Suva city centre. Mayfly nymphs were sampled from riffles in each stream by lifting ten rocks and vigorously brushing the surface of each with a soft brush while a fine-mesh net was held down stream. All mayfly nymph specimens were preserved in 80% ethanol until being examined under a dissecting microscope and identified to family leve l according to Dean and Suter (1996). Five samples of nymphs were collected from five replicate sites in each stream (approximately 10m of stream length) on each stream. The samples collected within each site wer e then pooled.
The distributive impact of terms of trade shocks

The halving of oil prices, which happened in a short period between late 2014 and the first months of 2015, has generated major terms of trade losses for oil exporting countries. Even if the oil producing sector normally employs a small group of workers and oil export revenues tend to be concentrated in a few firms and in government accounts, these relative price changes have economy-wide effects and significant distributive impacts. This paper describes and quantifies the channels of transmission from the drop in oil prices, to changes in welfare distribution at the household level. Using a macro-micro simulation model, the paper assesses how this shock affects poverty, inequality, and shared prosperity for the case of the Russian Federation. The oil price reduction generates a reverse Dutch disease that impacts sectoral employment, factor returns, and consumption prices. It causes a contraction of employment and wages in more skill-intensive (non-tradable) sectors, and a reduction in consumption prices that is more pronounced for nonfood than for food goods. When these shifts are mapped to changes in incomes at the micro level, all households are affected. Poverty rates could increase by 1 to 4 percentage points, depending on the poverty line used. At the US$10 a day threshold, for example, 4.1 million additional people fall into poverty. Along the consumption distribution, richer people are affected more than those in the bottom 40 percent. However, this minor progressive impact may be reversed due to increases in unemployment and cuts in social programs (transfers).
Perception, Cognition, and Response: A Recognition Systems Analysis of Avian Egg Rejection

To claim and understand the uniqueness of any physical, chemical, or biological system, it is necessary to use the same set of approaches, tools, and analyses to probe other systems. Accordingly, to assess whether and how people are unique in their perceptual, cognitive, and behavioural skills and algorithms when making decisions, a parallel set of studies is required to examine how human and non-human animals would respond. This thesis provides a structured experimental analysis of each of the recognition system’s components; perception, cognition, and response; in the context of avian brood parasitism. The study species are several potential hosts of brood parasitic birds but an explicit aim of this work to provide a reference for future studies on how to probe the perceptual, cognitive, and response traits in non-verbal experimental paradigms, including non-hosts and working with people. Hosts of avian brood parasites represent a powerful experimental system in which to study well defined and evolutionarily relevant behavioural decision: brood parasitic birds lay their eggs in other nests and the costs of parental care and reduced reproductive success are borne by the hosts. Hosts, in turn, may reject costly parasitism by ejecting foreign progeny or deserting parasitized nests. The cues used by hosts to perceive, recognize, discriminate, and respond to foreign eggs have been well studied in a variety of avian host-parasite systems. How, in turn, the hosts’ sensory and cognitive processes receive, sort through, and determine the behavioural responses to these cues, remains mostly unclear. The main chapters of the thesis set out to describe the results of two unpublished studies on hosts’ recognition systems. The first study uses artificial colour manipulation of hosts’ own eggs to determine whether specific colours are perceived similarly to trigger rejection behaviours, irrespective of the presence of hosts’ own eggs in the nest. The results suggest that foreign egg colours are perceived similarly and rejection is triggered through comparisons with internal filters, or recognition templates, even when hosts’ own eggs are not present. The second study also uses artificial colour manipulation to assess the hosts’ specific behaviours to foreign eggs and reveals that relative patterns of egg ejection and nest desertion are indicative of hosts’ responses to foreign eggs. These results provide detailed new information for our understanding of parasitic birds’ impacts on hosts’ perceptual processes. It is also the aim of this thesis that these studies may also be used as starting points towards a sample set of methodological and analytical tools to determine whether and how other species, including people, may use similar perceptual, cognitive, and behavioural decision rules to detect foreign items in odd-egg-out paradigms.
Determining the Optimal Number of Cluster Suppliers under Supply Failure Risks

As the risk of supply disruption becomes an important concern for a purchasing company, determining the optimal number of suppliers becomes a top priority in making purchasing decisions to address the supply risk to the manufacturer’s operation. Furthermore, the recently increasing co-location of dedicated supplier clusters has been observed for wider development to reduce supplier numbers, increasing geographical proximity within supply chain networks However, previous studies only discussed the risks of supply disruption in terms of super and unique events, neglecting the probability of the occurrence of a localised semi-super event , which can disrupt all suppliers in a specific geographical location. The present study extends the existing models, allowing a more realistic decision-making process according to the optimal number of cluster suppliers by considering the partial loss associated with independent supply risks in specific geographical regions, which constitute the important components of the overall supply disruption risk. Model comparison and sensitive analysis are conducted on the proposed model. The results indicate that the optimal solution is significantly influenced by the supplier failure probabilities in geographical regions when the ratio of loss versus variable operational cost increases.
Crop diversity and nutrition in west java

Small‐scale, subsistence agriculture in Java has an exceptional diversity of interplanted crops — a diversity that is declining as farm sizes decrease due to population growth and greater emphasis is placed on the most profitable crops for an expanding market economy. The nutritional consequences of these changes can be examined by examining interrelationships between household economic status, market involvement, dietary preferences, crops employed, crop yields and food consumption. The large quantity of rice in the Javanese diet frequently leads to deficiencies in the production and consumption of calcium, iron, riboflavin and vitamin A. Mixed‐cropping fields and homegardens are the major source of these critical vitamins and minerals. The production of these vitamins and minerals is greater in fields and gardens with a greater diversity of interplanted crops. Some Javanese families do not have sufficient land to produce all the food they need. In addition to the vitamins and minerals mentioned above, c.
Effects of Various Simulation Conditions on Latent-Trait Estimates: A Simulation Study

The aim of this simulation study, determine the relationship between true latent scores and estimated latent scores by including various control variables and different statistical models. The study also aimed to compare the statistical models and determine the effects of different distribution types, response formats and sample sizes on latent score estimations. 108 different data bases, comprised of three different distribution types (positively skewed, normal, negatively skewed), three response formats (three-, five- and seven-level likert) and four different sample sizes (100, 250, 500, 1000) were used in the present study. Results show that, distribution types and response formats, in almost all simulations, have significant effect on determination coefficients. When the general performance of the models are evaluated, it can be said that MR and GRM display a better performance than the other models. Particularly in situations when the distribution is either negatively or positively skewed and when the sample size is small, these models display a rather good performance.
Erectile dysfunction: The interest of the scientific community

Erectile dysfunction (ED) (impotence) can be define d as a partial or total inability to achieve erecti on, an inconsistent ability to do so, or a tendency to sustain only brief erections. The interest of the scientific community in studies about ED is evident and is increasing. The aim of this work was to evaluate the number of publications (NP) in ED usin g the databank PubMed in the period between1950 to January 2011 determining the NP, in each year, i n ED (NP-ED) and in impotence (NP-IM) alone or together (NP-ED-IM). The total NP-ED or NP-IM was a ssociated with Viagra (NP-ED-V or NP-IM-V), or Levitra ((NP-ED-L or NP-IM-L), or Cialis (NP-ED-C o r NP-IM-C) or physiotherapy (NP-ED-Physio or NP- IM-Physio). The results showed a growing interest o f the scientific community in ED. Viagra has been most cited drug and the physiotherapy is cited sinc e 1991 to treat ED. The findings reported reveal th e relevance of the PubMed to evaluate the scientific interest in specific subjects. Furthermore, the knowledge of these findings would be relevant to ve rify the scientific interest in ED that has undesirable impacts in our Society.
Assessing Small and Medium-Sized Farmers' Willingness to Produce Alternative Biofuel Feedstocks

The study assessed the willingness of small and medium-sized farmers to produce alternative biofuel crops in Louisiana and Mississippi. Data were collected from a random sample of 304 participants. The results revealed that the majority of the respondents were males, African Americans, over 50 years, part-time farmers, and a third earned less than $1,000 per year from farming. Most of the respondents (75%) indicated an interest in alternative fuel development, and 72% do not use alternative fuels in their operations. Also, a majority of respondents (83%) indicated that they would like to learn more about opportunities for alternative fuel development; 90% were in favor of alternative fuel development, and 87% were in favor of using alternative fuel on-farm. These results will be used to develop outreach programs to increase adoption of alternative crops in Louisiana and Mississippi; thus, increasing the potential for profitability for small and medium-sized farmers.
The relationship between radio power at 22 and 43 GHz and black hole properties of AGN in elliptical galaxies

We investigate the relationship between radio power and properties related to active galactic nuclei (AGNs). Radio power at 1.4 or 5 GHz, which has been used in many studies, can be affected by synchrotron self-absorption and free-free absorption in a dense region. On the other hand, these absorption effects get smaller at higher frequencies. Thus, we performed simultaneous observations at 22 and 43 GHz using the Korean VLBI Network (KVN) radio telescope based on a sample of 305 AGN candidates residing in elliptical galaxies from the overlap between the Sloan Digital Sky Survey (SDSS) Data Release 7 and Faint Images of the Radio Sky at Twenty-Centimeters (FIRST). About 37% and 22% of the galaxies are detected at 22 and 43 GHz, respectively. Assuming no flux variability between the FIRST and KVN observations, spectral indices were derived from FIRST and KVN data and we found that over 70% of the detected galaxies have flat or inverted spectra, implying the presence of optically thick compact regions near the centres of the galaxies. Core radio power does not show a clear dependence on black hole mass at either low (1.4 GHz) or high (22 and 43 GHz) frequencies. However, we found that the luminosity of the [OIII] λ5007 emission line and the Eddington ratio correlate with radio power more closely at high frequencies than at low frequencies. This suggests that radio observation at high frequencies can be an appropriate tool for unveiling the innermost region. In addition, the luminosity of the [OIII] λ5007 emission line and the Eddington ratio can be used as a tracer of AGN activity. Our study suggests a causal connection between high frequency radio power and optical properties of AGNs.
Dynamic Brazilian Test for Mechanical Characterization of Ceramic Ballistic Protection

The aim of this work is to identify the tensile strength of alumina (Corbit98), by performing Brazilian tests at different loading rate. In this kind of test, generally used for brittle material in static loading conditions, a cylindrical specimen is diametrically compressed and failure is generated in the middle of the component as a consequence of a positive tensile stress. In this work, this experimental technique was applied also in dynamic loading conditions by using a setup based on the Split Hopkinson Pressure Bar. Due to the properties of the investigated material, among which are high hardness, high compressive strength, and brittle behaviour, some precautions were needed to assure the validity of the tests. Digital Image Correlation techniques were applied for the analysis of high framerate videos.
Read my lips: The case against election promises

We study a model in which politicians differ in their ability to im- plement some policy. In an election, candidates make binding promises regarding the plans they will implement. These serve as a signal of true ability. In equilibrium, candidates make overambitious promises. The candidate with the highest ability wins. Yet, the electorate may be better off having a random candidate implement her best plan, rather than seeing the election winner implementing an overambitious plan. This is more likely if the distribution of abilities is skewed toward high values, in the case of private benefits from being elected, or if parties select candidates.
The Effect of CRM System on Sales Man-agement Control: A Case Study

Whereas prior research has paid little attention to the effect of CRM system on internal process control, this case study illustrates control-related CRM usage by investigating how effective sales management control through CRM and why. Results show that the CRM application can strengthen formal control and informal control simultaneously. These control modes are made feasible by enhanced outcome measurability, task programmability, and process visibility of sales work brought by CRM. CRM also sets the benchmark of sales ideals and serves as an effective self-management tool.
Corporate dividend decisions and dividend smoothing: New evidence from an empirical study of Turkish firms

Purpose - The purpose of this paper is to investigate the impact of regulations, reforms and legal environment on dividend policy in a different institutional setting. Particularly, it examines the firm-level cash dividend behaviour of publicly listed firms in Turkey in the post-2003 period, since there were major economic and structural reforms as well as significant regulatory changes of dividend payout rules imposed by the supervisory bodies. Design/methodology/approach - The paper focuses on a recent large panel data set of 264 Istanbul Stock Exchange (ISE)-listed firms over a ten-year period 2003-2012. First, it employs a modified specification of Lintner’s (1956) partial adjustment model for analysis regarding target payout ratio and dividend smoothing. Second, it performs a logit model for analysis in identifying the link between financial characteristics and the likelihood of paying dividends. Findings - The results show that ISE firms now follow the same determinants as suggested by Lintner. They, indeed, have long-term payout ratios and adjust their cash dividends by a moderate level of smoothing, and therefore adopt stable dividend policies (although less stable policies compared to their counterparts in the developed US market) as a signalling mechanism over the period 2003-2012. Moreover, the results also report that ownership structure concentration affects the target payout ratio and dividend smoothing in the Turkish market. In addition, the results further show that more profitable, more mature and larger sized ISE firms are more likely to pay cash dividends, whereas ISE firms with higher investment opportunities and more debt are less likely to distribute cash dividends in the post-2003 period. Originality/value - To the best of authors’ knowledge, this paper is the first major research that examines the implications of reforms and regulations on cash dividend payments and dividend smoothing over time in Turkey during its market integration process in the post-2003 period.
THE MODERATOR EFFECT OF INCOME AND SOCIAL STATUS, SOCIAL CONNECTEDNESS AND PHYSICAL ACTIVITY ON HEALTHY AGEING AMONGST OLDER ADULTS IN IBADAN METROPOLIS, NIGERIA

Old age is a developmental period of declining health and functioning. Developmental psychologists argued that living actively and successfully after the age of 65 implies healthy lifestyle habits that start as early as possible in life. Thus, it becomes imperative to examine the factors that could predict healthy ageing. This study investigated the moderating influence of income and social status, social connectedness and physical activity on healthy ageing among older adults. A total sample of 48 males and 39 females (87 subjects) between 65 and 80 years who participated in the study were volunteers recruited from institutions such as community centers, welfare centers, and church programmes for adults in Ibadan metropolis. Descriptive research design of correlation type was used in the study. Four standardized scales were administered to the respondents and the data obtained was analyzed using Pearson Product Moment Correlation (PPMC) and Multiple Regression analysis. Three research questions were raised and answered in the study. The result showed that healthy ageing significantly correlated with income and social status (r = .783; p<.05), social connectedness (r = .693; p<.05) and physical activity (r = .863; p<.05), independent variables (income and social status, social connectedness and physical activity) have significant effect on the healthy ageing of older adults(R =.711 & R 2 =.674) which means that the independent variables accounted for 67.4% in the prediction of healthy ageing. Each of the independent variables made a significant contribution to the prediction of healthy ageing and in term of magnitude of contribution, social connectedness made the most significant contribution (Beta= .663; t= .856; p<0.05) to the prediction while other variables made significant contributions in the following order: income and social status (Beta= .283; t= .503; p<0.05) and physical activity (Beta= .154; t= .375; p<0.05). Based on the finding of the study, it was recommended that older people should maintain social connection with family and friends. Government should adopt measures that could improve the economy of the country.
