Elucidation of Secondary Metabolites from Thyme Oil and Comparing its Antimicrobial Potential with Conventional Antibiotics against Uropathogens

 Abstract—GC-MS analysis of thyme oil showed the presence of various secondary metabolites comprising 13 components representing approximately 99% of the oil. The major components were carvacrol, thymol, terpinene-4-ol. The antimicrobial activity of thyme oil was assessed by disc diffusion method against uropathogens like Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus vulgaris, P. mirabilis and Staphylococcus aureus. The MIC was determined by broth microdilution method. The ZOI and MIC (%) were in the range of 19±3 mm and 0.08% (v/v equivalent) for E. coli; 14±4 mm and 0.25% for S. aureus; 16±4 mm and 0.04% for for Proteus mirabilis; 18±3 mm and 0.04% for Proteus vulgaris. Thyme oil showed low MIC values and high growth inhibition in comparison to 16 broad spectrum antibiotics tested. The result of the bioassay showed potent bactericidal properties of the oil.

A study of local turbulence and anisotropy during the afternoon and evening transitionwith an unmanned aerial system and mesoscale simulation

Abstract. Observations of turbulence are analysed for the afternoon and evening transition (AET) during the Boundary-Layer Late Afternoon and Sunset Turbulence (BLLAST) experimental field campaign that took place in Lannemezan (foothills of the Pyrenees) in summer 2011. The case of 2 July is further studied because the turbulence properties of the lower atmosphere (up to 300 m above ground level) were sampled with the Meteorological Mini Aerial Vehicle (M2AV) from turbulently mixed to stably stratified atmospheric conditions. Additionally, data from radiosoundings, 60 m tower and UHF wind profiler were taken together with the model results from a high-resolution mesoscale simulation of this case. Weak large-scale winds and clear-sky conditions were present on the studied AET case favouring the development of slope winds and mountain–plain circulations. It is found that during the AET the anisotropy of the turbulent eddies increases as the vertical motions are damped due to the stably stratified conditions. This effect is enhanced by the formation of a low-level jet after sunset. Finally, the comparison of the anisotropy ratio computed from the different sources of observations allow us to determine the most relevant scales of the motion during the AET in such a complex terrain region.
A Glancing Incidence Exafs Study of Evaporated Silver Films on Glass

A glancing incidence EXAFS experiment has been carried out with evaporated silver films on glass substrates. Prior to EXAFS data collection, a reflectivity curve was performed from which the critical angle for total external reflection of x-rays from surface were determined. The analysed EXAFS data revealed that there is a reduction in the coordination number and an increase in Debye-Waller factor compared to bulk values. These changes were explained in terms of grain size effect and the surface effects of the silver film.
Postingestive Feedback as an Elementary Determinant of Food Preference and Intake in Ruminants

Ruminants select nutritious diets from a diverse array of plant species that vary in kinds and concentrations of nutrients and toxins, and meet their nutritional requirements that vary with age, physiological state. and environmental conditions. Thus, ruminants possess a degree of nutritional wisdom in the sense that they generally select foods that meet nutritional needs and avoid foods that cause toxicosis. There is little reason to believe that nutritional wisdom occurs because animals can directly taste or smell either nutrients or toxins in foods. Instead, there is increasing evidence that neurally mediated interactions between the senses (i.e., taste and smell) and the viscera enable ruminants to sense the consequences of food ingestion, and these interactions operate in subtle but profound ways to affect food selection and intake, as well as the hedonic value of food. The sensation of being satisfied to the full (i.e., satiety) occurs when animals ingest adequate kinds and amounts of nutritious foods, and animals acquire preferences (mild to strong) for foods that cause satiety. Unpleasant feelings of physical discomfort (i.e., malaise) are caused by excesses of nutrients and toxins and by nutrient deficits, and animals acquire aversions (mild to strong) to foods that cause malaise. What constitutes excesses and deficits depends on each animal's morphology, physiology, and nutritional requirements. This does not mean that ruminants must maximize (optimize) intake of any particular nutrient or mix of nutrients within each meal or even on a daily basis, given that they can withstand departures from the normal average intake of nutrients (i.e., energy-rich substances, nitrogen, various minerals, and vitamins). Rather, hemostatic regulation needs only some increasing tendency, as a result of a gradually worsening deficit of some nutrient or of an excess of toxins or nutrients, to generate behavior to correct the disorder. Extreme states should cause herbivores to increase diet breadth and to acquire preferences for foods that rectify maladies. From an evolutionary standpoint, mechanisms that enable animals to experience feedback, sensations such as satiety and malaise, should be highly correlated with nutritional well being, toxicosis, and nutritional deficiencies, which are directly related with survival and reproduction.
Contribution of increased Agulhas leakage to tropical Atlantic warming

The upper tropical Atlantic Ocean has markedly warmed since the 1960s. It has been shown that this warming was not due to local heat fluxes, and that the trade winds that drive the coastal and equatorial upwelling have intensified rather than weakened. Remote forcing might thus have played an important role. Here model experiments are used to investigate the contribution from an increased inflow of warm Indian Ocean water through Agulhas leakage. A high-resolution hindcast experiment with interannually varying forcing for the time period 1948 to 2007, in which Agulhas leakage increases by about 45% from the 1960s to the early 2000s, reproduces the observed warming trend. To tease out the role of Agulhas leakage, a sensitivity experiment designed to only increase Agulhas leakage is used. Compared to a control simulation it shows a pronounced warming in the upper tropical Atlantic Ocean. A Lagrangian trajectory analysis confirms that a significant portion of Agulhas leakage water reaches the upper 300m of the tropical Atlantic Ocean within two decades, and that the tropical Atlantic warming in the sensitivity experiment is mainly due to water of Agulhas origin. Therefore, it is suggested that the increased trade winds since the 1960s favor upwelling of warmer subsurface waters, which in parts originate from the Agulhas, leading to higher SSTs in the tropics
Selection into Employment Sectors in Urban Ghana and Tanzania: The Role of Education

Recent debate among policy makers and researcher has centered on whether informal sector employment is a result of competitive market factors or labour market segmentation. This study contributes to the empirical literature by analysing selection into employment sectors in urban labour markets of Ghana and Tanzania using worker surveys from 2004 to 2006 in pooled sample models. Results from occupational choice models suggest both labour markets are characteristic of preference for formal sector employment with education. Results based on age differences indicate heterogeneity in job attainment as young people are found to face more challenges in accessing jobs.

OPTIMISATION OF PTA-ELISA DETECTION AND QUANTIFICATION OF BOTRYTIS CINEREA INFECTIONS IN GRAPES

Botrytis cinerea can be detected in juice pre- and postharvest using the monoclonal antibody BC-12.CA4 in plate trapped antigen-enzyme linked immunosorbent assays (PTA-ELISA). The amount of antigen predicted by PTA-ELISA was found to increase as grape juice samples were progressively diluted. This effect was also observed in B. cinereacontaminated boysenberry and blackcurrant juice samples. Detection of B. cinerea infections by PTA-ELISA was improved by incubation of grapes at 20oC for 48 h and was similar to visual assessments of infected grapes. PTA-ELISA is faster (1-3 days) than visual B. cinerea assessments (10-14 days). PTA-ELISA measurements can be standardised, removing human bias in determining B. cinerea infection levels.
Organizational Factors, Construction Risk Management andGovernment Regulations in Nigerian Construction Companies: Data Screening and Premilinary Analysis

The aim of this paper is to investigate the accumulated data pertaining to the organizational factors, construction risk management and government regulations in Nigerian construction companies. A total sample of 238 were selected from the total population of 338 contractors (i.e., contract manager, executive director, marketing manager, project manager and engineers) operating in Abuja and Lagos State construction companies in Nigeria. Therefore, a proportionate stratified random sampling approach was employed for this study to further divide the companies into different strata, and they were all picked randomly from each stratum. Furthermore, data cleaning and screening were conducted with the intent to fulfil the multivariate analysis assumptions. Hence, this study carried out various tests like missing data analysis, outliers, normality, Multicollinearity, non-response bias and common method variance with the use of Statistical Package for Social Science (SPSS) v21. Lastly, it was discovered that the data fulfil all the requirements for multivariate analysis.
First Observation of a Natural Hybrid Between Endangered Roanoke Logperch (Percina rex) and Chainback Darter (Percina navisense)

I used meristic, mitochondrial DNA, and nuclear DNA methods to infer the most likely ancestry of a putative hybrid specimen of Percina captured in the Roanoke River of Virginia. Potential parental species included Percina rex, P. nevisense, and P. roanoka. All nine of the meristic characters that I counted for the putative hybrid were within the published ranges of counts for P. nevisense, whereas counts for five characters were outside of published ranges for either P. roanoka or P. rex. These results were consistent with pure P. nevisense ancestry as well as various hybridization scenarios. Based on analysis of 1037 bp of the ND2 mitochondrial gene, the haplotype of the putative hybrid was identical to a known P. rex haplotype, but <86% similar to the closest-matching haplotypes for either of the other two species. Bayesian admixture analysis using seven nuclear microsatellite markers indicated a high probability of P. rex or P. nevisense ancestry and a low probability of P. roanoka ancestry. Taking all evidence together, the most parsimonious explanation is that the specimen was a hybrid between P. rex and P. nevisense.

Purpose: This paper identifies collaborative management of supply chain in an IT environment as the object of study. It offers discussion on the current situation and future development of supply chain management, the basic theories of supply chain management, and the comparison between the features of centralized management and collaborative management in an IT environment. It also points out the features and advantages of collaborative management of supply chain in an IT environment. Methodology: By way of analyzing the future development of supply chain management, this paper analyzes the advantages of collaborative management over centralized management. It also explores its implications and its requirements of interaction between onstage and backstage platforms. Findings: This paper lists the seven prominent features of collaborative management of supply chain in an IT environment, including being Internet-based, virtual, interrelated, and so on. In addition, it points out its advantages, such as collaborative decision-making, system-orientation, the establishment of a new cooperative relationship, etc. Application and limitations: This paper is an attempt to call on enterprises to update their current supply management system to collaborative management of supply chain in an IT environment. In this way, they can be more competitive in terms of supply chain. But this paper focuses only on its advantages and does not offer suggestions as to how to establish such a system.
Microscopic Modelling of Active Bacterial Suspensions

We present two-dimensional simulations of chemotactic self-propelled bacteria swimming in a viscous fluid. Self-propulsion is modelled by a couple of forces of same intensity and opposite direction applied on the rigid bacterial body and on an associated region in the fluid representing the flagellar bundle. The method for solving the fluid flow and the motion of the bacteria is based on a variational formulation written on the whole domain, strongly coupling the fluid and the rigid particle problems: rigid motion is enforced by penalizing the strain rate tensor on the rigid domain, while incompressibility is treated by duality. This model allows to achieve an accurate description of fluid motion and hydrodynamic interactions in moderate to concentrated active suspensions. A mesoscopic model is also used, in which the size of the bacteria is supposed to be much smaller than the elements of fluid: the perturbation of the fluid due to propulsion and motion of the swimmers is neglected, and the fluid is only subjected to the buoyant forcing induced by the presence of the bacteria, which are denser than the fluid. Although this model does not accurately take into account hydrodynamic interactions, it is able to reproduce complex collective dynamics observed in concentrated bacterial suspensions, such as bioconvection. From a mathematical point of view, both models lead to a minimization problem which is solved with a standard Finite Element Method. In order to ensure robustness, a projection algorithm is used to deal with contacts between particles. We also reproduce chemotactic behaviour driven by oxygen: an advection-diffusion equation on the oxygen concentration is solved in the fluid domain, with a source term accounting for oxygen consumption by the bacteria. The orientations of the individual bacteria are subjected to random changes, with a frequency that depends on the surrounding oxygen concentration, in order to favor the direction of the concentration gradient.
Body mass index of adolescents: comparison among different references

Objective: To compare the performance of the references (National Health and Nutrition Examination Survey I, National Center for Health Statistics/2000, International Obesity Task Force and Pesquisa Nacional sobre Saude e Nutricao) to assess the nutritional status of children and adolescents with the new reference of body mass index values proposed by the World Health Organization in 2007. Methods: Cross-sectional study that enrolled a nonprobabilistic sample of 5,122 children and adolescents of low socioeconomic status. In the matrix study, sample size was calculated in order to identify the association between blood pressure changes and stunting in different nutritional status. This interim report relates to the comparison among different references for assessment of nutritional status. Cochran’s Q, McNemar, chi-square and Kappa statistics were used to compare the proportion of underweight and overweight by different references and the agreement among them.

Property Value, Urban Quality and Maintenance Condition: A Hedonic Analysis in the City of Naples, Italy

The article examines the relationship between property value and level of conservation of public urban space. While many studies have examined the effect of proximity of open space, parks, and trees on property value, there has been few examination of how projects of urban revitalization and ordinary and extraordinary maintenances of public spaces can influence property values. While intuition can suggest that a low level of quality and maintenance of a public space can negatively affect property value, even if the standard requirement of public spaces and services are meet, this yet to be empirically proven.We proposes the application of a new econometric models for quantitative analysis of the characteristics of real estate property (Generalized Additive Model), to assess the impact of maintenance condition on property values, due to the better prevision that these functions can obtain in a real estate market context.The control of the formal and logical adequacy of the proposed theoretical model is referred to the case study under analysis, in the city of Naples. The results obtained show that a well preserved urban environment influences property price by approximately 6%. The experimental test of the model has provided results that, by reason of their formal consistency with the results obtained in other contexts, can be considered representative of the effectiveness of the methodology proposed.
Safety Effects of Fixed Automated Spray Technology Systems

Fixed automated spray technology (FAST) has emerged as a solution to provide quick, effective service delivery to high-risk locations prone to icy conditions or with high traffic volumes. The Colorado Department of Transportation has installed and used FAST on bridges since 1998, with 32 units currently installed on bridges around the state. There is some concern regarding the effectiveness of FAST in reducing accidents during winter weather. Previous studies of FAST have considered the changes to crash occurrence following deployment, but these studies were basic and compared seasonal figures or rates without accounting for site conditions. To address this shortcoming, an observational before–after study with the empirical Bayes technique was used to determine the effect of FAST systems on crash frequencies. The results revealed that at sites where crashes were reduced, FAST systems contributed to an annual reduction of 2% on multilane rural highways, 16% to 70% on urban Interstates, 31% to 57% on rural Interstates, and 19% to 40% on interchange ramps between Interstates. However, at some sites, safety deteriorated with an increase in crashes. Although the precise causes of such increases are not completely clear, they may have been the result of increased traffic, systems not being maintained properly, or systems applying fluids in improper amounts or at the wrong time. On the basis of the collective results, high-traffic, high-crash severity locations are most suitable for FAST deployment.

The Influence of Compassion Satisfaction and its Effect on the Nurse-Patient Relationship

Background: Nurse caring is the most influential dimension of predicting patient advocacy, outcomes, and overall satisfaction. A nurse with compassion satisfaction is more able to provide a caring atmosphere in healthcare. Objectives: The purpose of this integrative literature review is to analyze the impact of compassion satisfaction on nurses and the nurse-patient relationship. Method: The integrative literature review for this study included searches of CINAHL, PubMed, and PsychInfo. A search using the keywords “(compassion fatigue OR compassion satisfaction) AND (nursing practice OR nursing staff)”. Results: Compassion satisfaction had a significant impact on the success of nurses in healthcare. Demographic and work environment were major factors in determining the level of compassion satisfaction of a nursing staff. A direct correlation was found between a nurse’s ability to care and patient satisfaction. This correlation lead to a more successful nurse-patient relationship and better patient outcomes. Conclusion: Fostering compassion satisfaction and providing the framework to prevent compassion fatigue will improve nurse caring and potentially provide a sustained improvement in the nurse-patient relationship.

The role of the principal, teachers and students in restoring the culture of learning, teaching and service (COLT) in black secondary schools in the Pretoria region

Political and social instability over many years has led to a crisis in the South African education system. One of the crucial changes and challenges that the new democracy faces is to reconstruct a society and an education system that will be able to establish a culture conducive to learning, teaching and services in schools (COLT). This article examines factors that have led to a loss of the culture of learning and teaching (COLT) in South African schools, and the characteristics of a positive culture expected by principals, teachers and students. Results indicate that although principals are attempting to influence this culture, there is little support for such changes from teachers and students.
