Recall of Theoretical Pharmacology Knowledge by 6th Year Medical Students and Interns of Three Medical Schools in Riyadh, Saudi Arabia

The aim of this research is to provide some insights into the ability of the sixth year medical students and interns to recall theoretical knowledge of pharmacology. A cross-sectional study was conducted among students who graduated from three different medical schools in Riyadh, Saudi Arabia. A questionnaire was distributed to male and female students in 3 different colleges of medicine. The questionnaire included demographic information and ten multiple choice questions (MCQs) on basic pharmacology. Out of the 161 students, there were 39 females (24%) and 122 males (76%). A total of 36 (22%) students studied at a traditional learning school whereas 125 (78%) students studied at problem based learning (PBL) schools. The students were recruited from three universities: KSU, KSAU-HS, and KFMC-COM. In general, 31 students (19%) of the participants scored ≥ 7 out of 10, 77 students (48%) of them obtained a correct score of (4–6) out of 10, and 53 students (33%) scored less than 4. The study showed no statistically significant difference in recalling pharmacology between traditional school and problem based learning school except for those who prepared for exams. Results suggest that pharmacology is a difficult subject. Reevaluations are needed in the way of teaching pharmacology.
Research review of college students' psychological quality

Quality education forms an important content of tertiary education reform and is at the same time a basic requirement for talent cultivation in the future society. Psychological education, one constituent of the said quality education, is of great significance for the overall development of college students. In recent years, some psychologists have carried out many valuable discussions on college students' psychological quality. This paper is thus composed as a review of researches done in the past decade on the current situation of college students' psychological quality and the factors that influence it.
Resource capacities supporting thematic approach in teaching ECDE Centres in Uasin Gishu County

Teachers are important resources in the teaching and learning process and should therefore be considered alongside other learning resources. They are the best recourses to be built into a particular teaching strategy designed to achieve a specific learning practice for instance thematic approach, without which can be administrative problem to head-teachers. Without adequate resource materials, it is a drawback to the implementation of new ideas and techniques. The study sought to investigate resource capacities of ECDE centers in supporting thematic approach in teaching in early childhood development centers in Eldoret Municipality. It was guided by Kurt Lewin’s Three Stages of Change Model developed in 1954. The study adopted the Descriptive Survey research Design. The target population comprised 266 respondents comprising of 164 ECDE teachers, 82 head teachers and 20 Educational Officials. Stratified sampling was used to select thirty schools out of eighty two schools; Public and Private Schools which translated to 30% of the total sample population. Purposive sampling was used to select all the head teachers to participate in the study while random sampling was also used to select one ECDE teacher. Instrumentation included the questionnaire, interview guide and document analysis. Data was collected and analyzed using descriptive statistics. Majority of the ECDC’s have inadequate resources and capacities both physical and human required supporting the implementation of thematic approach in teaching ECD children. The head teachers who supervise the curriculum in their schools are also not ECDE compliant hence, may not have be in a position to advice the teachers concerning the approach appropriately. The study recommended that ECDCs be equipped with adequate and developmentally appropriate materials and resources.
Faculty Adoption of Teaching and Learning Technologies: Contrasting Earlier Adopters and Mainstream Faculty

The adoption of teaching and learning technologies is an innovation that challenges the structure, culture and practice of modern research universities. This paper documents quantitatively and qualitatively the attitudes, skills and behavior of the faculty related to the use of instruc- tional technology at a large Canadian research university. The data was gathered from a survey (n = 557) of teaching faculty. The data is ana- lyzed with respect to Roger's (1995) categories of adoption of innova- tion differentiating "Earlier Adopters" (EAs) from "Mainstream Faculty" (MF). The paper discusses four factors that have tended to create a "chasm" between these two groups and discusses strategies for reducing the chasm and providing support and incentive for all faculty in the adoption of instructional technologies.
Some New Fractional-Calculus Connections between Mittag–Leffler Functions

We consider the well-known Mittag–Leffler functions of one, two and three parameters, and establish some new connections between them using fractional calculus. In particular, we express the three-parameter Mittag–Leffler function as a fractional derivative of the two-parameter Mittag–Leffler function, which is in turn a fractional integral of the one-parameter Mittag–Leffler function. Hence, we derive an integral expression for the three-parameter one in terms of the one-parameter one. We discuss the importance and applications of all three Mittag–Leffler functions, with a view to potential applications of our results in making certain types of experimental data much easier to analyse.
The controlling factors of photochemical ozone production in Seoul, South Korea

Author(s): Kim, S; Jeong, D; Sanchez, D; Wang, M; Seco, R; Blake, D; Meinardi, S; Barletta, B; Hughes, S; Jung, J; Kim, D; Lee, G; Lee, M; Ahn, J; Lee, SD; Cho, G; Sung, MY; Lee, YH; Park, R | Abstract: © Taiwan Association for Aerosol Research. We present the ambient ozone and relevant observed trace gas dataset in Seoul, South Korea, during the Megacity Air Pollution Studies (MAPS)-Seoul field campaign from May to June of 2015 (MAPS-Seoul 2015). We observed two distinctive periods, one with higher and the other with lower daytime ozone levels despite mostly clear conditions for both periods. The importance of peroxy radical contributions to excess ozone production is illustrated by the substantial differences in the Leighton constant (Φ) for the two periods. Moreover, higher levels of hydroxyl radical (OH) reactivity (s–1) were observed during the high ozone episode compared to the low ozone episode by as much as ~5 s–1. The contributions of nitrogen oxides (NOx) to OH reactivity become less important than those of volatile organic compounds (VOCs) during the high ozone episode, which suggests the NOx saturated ozone production regime. It was also notable that the biogenic VOC isoprene consistently contributed the most to OH reactivity from among the observed VOCs during the afternoon throughout the whole field campaign. Finally, we ran multiple box model scenarios to evaluate the ozone production rates of three different air mixtures: a high ozone mixture, a low ozone mixture, and a simulation of the regional air quality. The results indicate that the total OH reactivity levels and the relative contributions of VOCs to NOx play critical roles in ozone production rates. The simulated air quality mixture results in lower OH reactivity, causing lower ozone production rates than those calculated for the high ozone mixture, which clearly indicates the need for further improvements in the regional model to accurately simulate ozone precursors in the region. The results of this study suggest that a comprehensive trace gas dataset combined with observations of the OH reactivity enables us to properly diagnose the photochemistry behind ozone pollution, leading to effective ozone abatement policies.
Highly asymmetric magnetic domain wall propagation due to coupling to a periodic pinning potential

Magneto-optical microscopy and magnetometry have been used to study magnetization reversal in an ultrathin magnetically soft (Pt/Co)2 ferromagnetic film coupled to an array of magnetically harder (Co/Pt)4 nanodots via a predominantly dipolar interaction across a 3 nm Pt spacer. This interaction generates a spatially periodic pinning potential for domain walls propagating through the continuous magnetic film. When reversing the applied field with respect to the static nanodot array magnetization orientation, strong asymmetries in the wall velocity and switching fields are observed. Asymmetric switching fields mean that hysteresis of the film is characterized by a large bias field of dipolar origin which is linked to the wall velocity asymmetry. This latter asymmetry, though large at low fields, vanishes at high fields where the domains become round and compact. A field-polarity-controlled transition from dendritic to compact faceted domain structures is also seen at intermediate fields and a model is proposed to interpret the transition.
Adsorption of phenol from aqueous media by an agro-waste (Hemidesmus indicus) based activated carbon.

The adsorption of phenol by an agro-waste based activated carbon prepared from the root residue of Hemidesmus Indicus (HIC) was investigated to assess its possible use as adsorbent. The effect of various factors, namely, pH, initial adsorbate concentration, adsorbent dosage and contact time were studied to identify adsorption capacity of HIC. The results were compared to that obtained from adsorption of phenol by commercial activated carbon (CAC). Adsorption data were modeled with the Langmuir and Freundlich isotherms. The kinetic models were also applied for the pseudo-first-order, pseudo-second-order, intra-particle diffusion and pore diffusion coefficients. Although HIC and CAC showed much similar isotherm models and kinetics, yet HIC was found to show much higher boundary layer effect and pore-diffusion coefficients, in relation to CAC.
An Experimental Study of Mixed, Forced, and Free Convection Heat Transfer From a Horizontal Flat Plate to Air'

The paper Wang described experiments in which a flat plate was heated nonuniformly across the width of a wind tunnel, although the data were treated as though the heating were uniform. A description of the experiments noted that a central heater. with a width of 40 percent of the channel width, was sup plemented by two guard heaters that were used to minimize the transverse heat transfer. Transverse temperature details were not given. Ordinarily this procedure is satisfactory for convective heat transfer, and a number of studies have produced acceptable results. Wang indicated that his data could be used to verify theoretical criteria that determine the conditions marking the onset of longitudinal vortex rolls in a horizontal Blasius flow. These criteria, developed by Wu and Cheng [14], apply to a flat plate heated uniformly and isothermally from below or cooled isothermally from above.
Seeded wheatgrass yield and nutritive quality on New Mexico big sagebrush range.

Establishment, yield, and nutritional quality of 'Nordan' crested wheatgrass (Agropyron desertorum [Fischer ex Link] Schultes), 'Fairway' crested wheatgrass (Agropyron cristatum [L.] Gaertner), 'Arriba' western wheatgrass (Pascopyrum smithii [Rydb.] A. Love), 'Luna' pubescent wheatgrass (Thinopyrum intermedium subsp. barbulatum [Schur.] Barkw. and D.R. Dewey), and 'Largo' tall wheatgrass (T. ponticum [Pod] Barkw. and D.R. Dewey) were evaluated on big sagebrush range (Artemisia tridentata Nutt. tridentata) in northcentral New Mexico during a 5-year study. All the above wheatgrasses showed high initial densities and long-term persistence. Wheatgrass yields across years and seasons during the last 2 years of study averaged 760 kg/ha compared to forage yields of 355 kg/ha on surrounding ungrazed native rangeland. There were no differences (P > .05) among wheatgrasses in standing crop of current year's growth during spring, summer, or fall. Crude protein concentrations did not differ (P > .05) among wheatgrasses with seasonal advance. However, all the wheatgrasses showed a consistent decline in nutritional quality from spring to summer to fall. All the wheatgrasses we studied will provide high-quality, spring (mid-April to mid-June) forage for livestock. During summer, use of native range is advantageous because it contains a high component of warm season grasses and forbs. Interseeding shrubs in wheatgrass seedings could reduce protein supplementation costs in winter.
Resource Allocation: Targeting Funding for Maximum Impact. Policy Brief.

Key Points: Targeted resource allocation especially benefits disadvantaged children. Although some early literature reviews suggest that additional school expenditures do not consistently improve student outcomes (Hanushek, 1989, 1994), other studies indicate that more resources can have a significant impact on the achievement of minority and disadvantaged students (Krueger, 2000; Finn & Achilles, 1990). These differences suggest that resource allocation does matter for many students — and that states and policymakers may benefit from a closer examination of where their resources are being spent.
Dynamic Capabilities as a Precursor to Corporate Innovation and Competitive Advantage: The Role of Human Capital

This paper presents a critical review of literature on the relationship between dynamic capabilities and innovation, and between innovation and competitive advantage of firms. It further explores the e ect that human capital has on these relationships.Theories of dynamic capabilities, resource-based view and resource advantage theory were used to support the literature provided for in the study. Relevance to innovation. The literature presented shows that dynamic capabilities supports innovation as the business environment changes and provides the foundation of firm-level competitive advantage. Various empirical studies highlighted demonstrate that to attain innovative performance, firms must be able to mobilize their resources and capabilities and dynamically align them with the changing environmental opportunities and customer needs.
Modelling of Social Key Performance Indicators of Corporate Sustainability Performance

Corporate social performance is discussed in this paper. The aim of this article is to propose indicators of social performance in the context of corporate sustainability. Relevance of the proposal has been verified through a questionnaire that focused on large manufacturing companies in the Czech Republic. Using statistical methods, it was found that a basic set of sixteen indicators can be replaced by six key performance indicators – Percentage of employees covered by collective agreement, Wage discrimination, Occupational diseases, Violations of ethical code, Expenditures on identifying and ensuring customer satisfaction and Percentage of products and services assessed for their influence on health and safety of customers. These results aim to contribute to both academy and corporate practitioners, who want to improve corporate social performance and through the use of key performance indicators to support transparency and sustainability of their business. This study, however, has some limitations. The key performance indicators are designed specifically for large manufacturing companies of group 27.1 CZ‑NACE.
Radar detection of signals with unknown parameters in K-distributed clutter

The detection of signals with unknown parameters in correlated K-distributed noise, using the generalised Neyman-Pearson strategy is considered. The a priori uncertainty on the signal is removed by performing a maximum likelihood estimate of the unknown parameters. The resulting receivers can be regarded as a generalisation of the conventional detector, but for a zero-memory nonlinearity depending on the amplitude probability density function of the noise as well as on the number of integrated pulses. It is shown that the performance for uncorrelated observations is unaffected by the specific signal pattern, but depends only on the signal-to-noise ratio; moreover, the effect of the clutter correlation on the performance can be accounted for simply by a detection gain. A performance assessment, carried out by computer simulation, shows that the proposed receivers significantly outperform conventional ones as the noise amplitude probability density function markedly deviates from the Rayleigh law. It also shows that the generalised Neyman-Pearson strategy is a suitable means of circumventing the uncertainty on wanted target echos since the operating characteristics of the receivers for the case of signals with unknown parameters closely follow those of the receiver for a completely known signal.
Stability and adaptability of upland rice genotypes

The aim of this study was to identify upland rice genotypes with high stability and adaptability by the GGE biplot method based on the predicted genotypic and phenotypic values. Of the 20 genotypes evaluated, 14 were lines developed by the cooperative program for rice improvement of Minas Gerais and six were controls. The GGE biplot analysis showed that cultivar BRS Pepita and MG1097 were closest to the ideal genotype. In the comparison of the fixed with the random models (% G + GE, prediction error sum of squares and correlation), it was observed that the use of phenotypic means in all comparative parameters indicated a lower predictive potential under simulated imbalance than the use of predicted genotypic values. The conclusion was drawn that BRS Pepita and MG1097 are ideal genotypes for southern Minas Gerais and that the predictive power of the phenotypic means underlying the study of stability and adaptability is lower than of genotypic means.
THE EFFECT OF INFRARED RADIATION IN MODIFYING NUTRITIONAL AND MECHANICAL PROPERTIES OF GRASS PEA SEEDS

The aim of this work was to evaluate the effect of exposure of grass pea seeds to IR (infrared) radiation applied at varying time intervals on their mechanical properties, trypsin inhibitor activity, and reactive lysine content. Grass pea seeds cv. Derek were exposed to IR radiation at 180°C for 30, 60, 90, 120, and 180 s, respectively. Compared with that of raw seeds, IR heating of grass pea seeds reduced trypsin inhibitor activity. Reactive lysine proved to be relatively stable in the applied heating conditions. In addition, the process led to the reduction in the value of breaking load required for the destruction of a single seed, which may facilitate further processing, for example, flaking. Therefore, IR heating can be used in processing grass pea seeds.
The Valley of Death, the Technology Pork Barrel, and Public Support for Large Demonstration Projects

Moving non-incremental innovations from the pilot scale to full commercial scale raises questions about the need and implementation of public support. Heuristics from the literature put policy makers in a dilemma between addressing a market failure and acknowledging a government failure: incentives for private investments in large scale demonstrations are weak (the valley of death) but the track record of governance in large demonstration projects is poor (the technology pork barrel). We reassess these arguments in the literature, particularly as to how they apply to sup- porting demonstration projects for decarbonizing industry. Conditions for the valley of death exist with: low appropriability, large chunky investments, unproven reliability, and uncertain future markets. We build a data set of 511 demonstration projects in nine technology areas and code characteristics for each project, including timing, motivations, and scale. We argue that the literature and the results from the case studies have five main implications for policy makers in making decisions about demonstration support. Policy makers should consider: 1) prioritizing learning, 2) iterative upscaling, 3) private sector engagement, 4) broad knowledge dissemination, and 5) making demand pull robust.
Effectiveness of Split-Plot Design over Randomized Complete Block Design in Some Experiments

One of the main features that distinguish split-plot experiments from other experiments is that they involve two types of experimental errors; the whole plot (WP) error and the split-plot (SP) error. This research paper compared the effectiveness of split-plot design (SPD) over randomized complete block design (RCBD). The data used for comparison is a 2 1 x 5 2 split-plot experiment with three replicates. It is been carried out to evaluate the threshing efficiency of an improved sorghum thresher; the three factors considered in the experiment are the feed at two different rates, moisture content at five different levels and speed at five different rates. The data is analyzed as split-plot and as randomized complete block design and their ANOVA results and relative efficiency (RE) statistic values were compared. The result reveals the effectiveness of split-plot design over randomized complete block design. Key words : SPD, SP error, WP error, RCBD, Relative Efficiency
Using Topology Optimization to Reduce Stress Concentration Factor in a Plate with a Hole

This paper focuses on reducing stress concentration in a plate with a hole. For this purpose, a novel Reliever Topological Material Elimination (RTME) approach was introduced which uses the topology optimization technique to specify the best areas to remove material in order to refine flow of stress and reduce the Stress Concentration Factor (SCF), consequently. Using the Solid Isotropic Material with Penalization (SIMP) method, topology optimization was formulated. Three major elimination areas were determined from material elimination patterns observed in topology optimization. Two possible RTME cases were proposed numerically. To evaluate the efficiency of the method, finite element analyses were conducted for one previous technique and the results werediscussed. In addition, the results of finite element analysis were validated by some experimental tests. According to the final results, RTME approach gives up to 35.5% stress reduction, 44% SCF mitigation, and decrease about 28% of the initial volume. In comparison with the previous technique, using RTME is more effective in decreasing the SCF and weight of the plate, simultaneously.
