Slippery When Wet

This article discusses the importance of airport runway friction testing. Since the technical challenges of ensuring satisfactory braking characteristics for aircraft in all runway conditions are significant, several friction testing research programs have been developed. One program, jointly sponsored by the Federal Aviation Administration and Transport Canada, has worked to develop a consistent friction scale for similar runway conditions in differing environments and to establish reliable correlation between ground vehicle friction measurements and the braking performance of aircraft. The demand for full-width runway testing has increased as data has become easier to retrieve, transmit and analyze electronically. Manufacturers are responding to this need for more accurate and more plentiful data by creating a new generation of fiction testers to provide airport operators with better facilities to record, interpret and act upon runway friction coefficient data.
An Experiment to Explore the Potential of Simulation for Improving Ready Mixed Concrete Delivery to Construction Sites

RMCSIM, a computer simulation package developed recently, can be used to simulate ready mixed concrete delivery operations for a concrete plant delivering concrete to multiple sites. RMCSIM simulation runs were reported in Tang et al (2005). A questionnaire survey (Ying and Tang, 2003) was also conducted for inding out what strategies might improve the matching of concrete delivery between plant and sites. The survey suggested two approaches: adjusting the time interval between consecutive truckmixer arrivals, and adjusting the time at loading of truckmixers at the concrete plant. This paper reports 900 simulation results for testing these two approaches, and recommends that a site manager should specify realistic time intervals between consecutive truckmixers. Guidance on this can be referenced to Tables 3a and 3b of this paper.
Turbidity Reduction and Monitoring Strategies for Highway Construction Projects

In 2009, the United States Environmental Protection Agency (USEPA) promulgated the Effluent Limitations Guidelines and Standards for the Construction and Development Point Source Category (40 CFR Part 450), known and the “C&D Rule”, requiring turbidity monitoring for larger construction sites and establishing a numeric effluent limitation of 280 NTU. Due to subsequent legal challenges, the numeric effluent limitation and monitoring requirements were stayed. Monitoring requirements were included in the USEPA’s 2011 proposed construction general permit, but were stricken from the finalized permit. Nevertheless, in January 2012, the USEPA solicited data and information on turbidity monitoring, implying that it is considering a potential future revision and reinstatement of some kind that would require turbidity monitoring that may be subject to a numeric effluent limitation or numeric action level. This report seeks to prepare state departments of transportation (DOTs) and others planning and implementing transportation-related construction projects for this potential eventuality by providing them with information on traditional and state-of-the-art turbidity reduction and monitoring practices. Two surveys were sent to state DOTs in an effort to gain information on the current state of the practice. Survey questions covered current erosion and sediment control practices, as well as turbidity monitoring practices in use in each state. These surveys provided detailed information for state DOTs desiring to compare their programs to those of other states. An analysis of these surveys is included in Appendix A. This appendix includes a number of references to documents produced by state DOTs that may assist others in the development of their programs.
THE BEHAVIOR OF MODEL REINFORCED WALLS ON SOFT SOILS

This paper presents the results of tests with reinforced model walls built on a soft foundation soil. The walls were loaded to failure by a rigid footing located at different positions on the wall top. Internal and external displacements of the wall and footing stresses were assessed during the tests. Stiff and extensible reinforcements were used to reinforce the fill material of the wall. The results obtained showed a marked influence of the foundation soil on the deformability of the wall, failure mechanisms in the fill and strength of the system. The reinforcement stiffness and the location of the footing also affected the results obtained.
İnsani Gelişmenin Ekonomik Büyümeye Etkisi: Geçiş Ekonomileri Üzerine Bir Uygulama

: Human development is defined as the process of accessing resources necessary for a healthy and good level of life of individuals. A country's level of human development is measured by the Human Development Index, which is used as a summary measure of health, education, and income indicators representing three dimensions of human well-being. Human development, which is an important factor in measuring human well-being, is also considered an important input in economic growth. The aim of this study is to analyze the effect of human development on economic growth using the panel data from 25 transition economy countries for the period 2002-2018. In the study, two different models were established on which the economic growth series depended. In the first model, only human development series is the independent variable. In the empirical findings obtained, it was found that economic growth increased as human development increased. In the second model, the unemployment series with human development are independent variables. In the second model findings, it is understood that economic growth increases as human development increases, similar to the first model. In addition, an inverse relationship between unemployment and economic growth has been identified in this model.
Developing a standardised manufacturing process for the clinical-scale production of human mesenchymal stem cells

Human mesenchymal stem cells (hMSCs) are a promising candidate for cell-based therapies given their therapeutic potential and propensity to grow in vitro. However, to generate the cell numbers required for such applications, robust, reproducible and scalable manufacturing methods need to be developed. To address this challenge, the expansion of hMSCs in a microcarrier-based bioreactor system was investigated. Initial studies performed in T-flask monolayer cultures investigated the effect of key bioprocess parameters such as dissolved oxygen concentration (dO2), the level of medium exchange and the use of serum-free media. 20 % dO2 adversely impacted cell proliferation in comparison to 100 % dO2, whilst FBS-supplemented DMEM was found to be the most consistent and cost-effective cell culture medium despite the advances in serum-free cell culture media. Several microcarriers were screened in 100 mL agitated spinner flasks where Plastic P102-L was selected as the optimal microcarrier for hMSC expansion given the high cell yields obtained, its xeno-free composition and effective harvest capacity. The findings from the initial small-scale studies culminated in the successful expansion of hMSCs on Plastic P102-L microcarriers in a fully equipped 5 L stirred-tank bioreactor (2.5 L working volume), the largest reported volume for hMSC microcarrier culture to date. A maximum cell density of 1.68 x 105 cells/mL was obtained after 9 days in culture; further growth was limited by the low glucose concentration and lack of available surface area. A novel, scalable harvesting method was also developed, allowing for the successful recovery of hMSCs. Importantly, harvested hMSCs retained their immunophenotype, multipotency and ability to proliferate on tissue culture plastic.

Adaptive directional overcurrent relay coordination using ant colony optimisation

The coordination of directional overcurrent relays is most commonly studied based on a fixed network topology within an interconnected power system. Due to its complexity and non-linearity, the relay coordination is formulated as an optimisation problem. Distribution systems often suffer consequences due to the dynamic changes of network topology and operation of elements. Such changes are for example the inputs and outputs of generators, lines and loads. The consequences are reduction of sensitivity and selectivity of relays. The principal objective of this study is to coordinate the directional overcurrent relays based on adaptive protection scheme. The secondary objective is to present the formulation of ant colony algorithm and a comparison of it with the genetic algorithm.
The national evaluation of Sure Start : does area-based early intervention work?

Book synopsis: Sure Start Local Programmes (SSLPs) were a major strategic effort by New Labour towards ending child poverty. By changing the way services were delivered to children under four and their families, through targeting and empowering highly deprived small geographic areas, SSLPs were intended to enhance child, family, and community functioning. Following five years of systemic research exploring the efficacy and impact of this grand experiment, this book pulls together the results of the extensive National Evaluation of Sure Start (NESS). It reviews the history of policies pertaining to child health and well being that preceded and set the stage for Sure Start. The book provides insight into how SSLPs were expected to function and how they actually operated, both in terms of their strengths and weaknesses, and their costs. The contributors: examine the nature of the communities in which these programmes were situated and how they changed over time; present the early effects of SSLPs on children and families, with evidence highlighting some small beneficial effects and some small deleterious ones; and extract specific features of SSLPs that contributed to whether individual programmes benefited children and families, providing a guide for the revision of programmes and policies. With a foreword from Naomi Eisdenstadt, former Director of the Sure Start Programme, and a concluding chapter by Prof. Sir Michael Rutter, member of the government's scientific advisory board overseeing NESS, the book provides a critique of SSLP policy and NESS.
ASYMMETRIC LOADING DURING THE HANG POWER CLEAN - THE EFFECT THAT SIDE DOMINANCE HAS ON BARBELL POWER SYMMETRY

The vertical ground reaction force (GRF) of both feet and bar end kinematics were recorded using force platforms and high speed video simultaneously during hang power clean (HPC) performance with typical training intensities, in order to determine whether perceived handedness and ground kinetic asymmetry influenced bar end kinematics. There were significant differences between the GRF when side dominance was determined from GRF asymmetries (p≤0.05), but not when determined by perceived handedness. Similarly, there were significant differences between bar end power outputs when they were determined according to bar end asymmetries but not when determined by perceived handedness or GRF asymmetry. These results suggest mechanisms other than ground kinetic asymmetries influence bar end power output symmetry.
Unraveling the genetic basis of drought tolerance in potato

Background: Potato is highly valued as a food security crop but is sensitive to drought stress. A relatively small reduction of the optimum amount of water can already result in a significant reduction in tuber yield. Therefore, unravelling the genetic basis of drought tolerance is important in order to enhance tolerance to drought in potato. We have evaluated a diploid potato backcross mapping population for drought tolerance under field conditions. Water application was withheld at the stage of tuber initiation. At the end of the drought stress period, we collected data on a number of morphological and physiological traits.Results: The potato population showed significant reduction in several growth traits measured, as well as in tuber yield. We applied quantitative trait locus (QTL) analysis to find genomic regions underlying these drought tolerance traits. We found 60 QTL for several of the traits measured under well-watered and drought stress conditions. From the total number of QTLs identified, 21 were detected under water stress conditions while 39 QTLs were identified under well-watered conditions. Drought specific QTLs for tuber fresh yield was detected on chromosome 7, 9 and 12.Conclusions: There is genetic variation in potato for drought tolerance and QTLs discovered for drought tolerance traits in this study can aid in improving potato for drought tolerance.
FATIGUE CLASSIFICATION OF WELDED JOINTS IN ORTHOTROPIC STEEL BRIDGE DECKS

The TRRL has carried out a number of investigations to assess the fatigue performance of welded joints in orthotropic bridge decks. The assessment method is based on the UK design code, BS 5400 part 10. Stresses due to traffic loading were obtained from static load tests on trial deck panels in the laboratory under a single wheel load, and on bridges using a two axle test vehicle. This report describes constant amplitude fatigue tests carried out on some of the main types of welded joint in two designs of deck panel used on bridges in the UK and elsewhere. The test results were used to assign the joints to the appropriate weld class in the design code. The joints tested were: the longitudinal stiffener (trough) to deck; alternative types of trough to crossbeam; trough splice; crossbeam to deck; longitudinal web to deck; and deck plate butt welds. For most joints the test specimen and loading were designed to simulate the passage of single wheels over the joint and fatigue strength can be expressed in terms of stress in the plate adjacent to the weld. It was found that several of the joints could be upgraded compared to the BS 5400 classifications, but inspection and quality assurance requirements are likely to limit the weld class which can be used for joints on bridges.
An Empirical Study on Factors Affecting Employee Loyalty in the Wood Processing Industry

In general, human resources are important aspects of any organization. In order to gain the loyalty of employees and stabilize the human resources department, management must always consider employee loyalty. In this study, the author seeks to determine which reward structure best promotes affects job satisfaction among employees, including the influence level of incentives, the support of superiors and promotions among hierarchical positions, and thereby most impacts their loyalty to the company. Using a theoretical foundation and practical studies on job satisfaction and employee loyalty, the author built a five-point Likert scale to determine the reward structure as well as the influencing level of each factor on employee loyalty. Additionally, this study determines the level of influence of three factors—Rewards, Empowerment, and Hierarchical Position—on the job satisfaction of employees, The interaction of job satisfaction and employee loyalty is a statistically significant indication of employee loyalty. In practical terms, this study illustrates the factors that affect the satisfaction of employees working at GiaVinh Co., Ltd.
Prevalence of ADHD symptoms and their correlations with mental health-related variables among medical student

Objectives Attention deficit hyperactivity disorder (ADHD) is a neurobehavioral development disorder contributed to social difficulties and affective problems. ADHD was evidently related to perceived stress, internet addiction and depression, leading to academic problems. However, ADHD symptoms among young medical student remains underreported. This study aimed to investigate the prevalence of ADHD and explore the association between ADHD symptoms and mental health-related conditions among medical students. Results Among 124 participants of first year medical students in Chiang Mai University, Thailand, 78 (62.9%) were female. The average age was 18.7 (SD 0.7). Thirty-one (25%) were considered as having ADHD symptoms based on the Adult ADHD Self-Report Scale screener (ASRS). The group with ADHD symptoms showed higher scores on the internet addiction test core (t = 3.27, p = .001), perceived stress scale (t = 2.94, p = .004) and Rosenberg Self-esteem Scale (t = 3.04, p = .003). No difference was found between groups regarding depression and perceived social support scores. However, the total score of ASRS appeared to significantly correlate with all these mental health- related variables. The relatively high prevalent may have contributed to invalid items of ASRS, for which a new or revised scale is needed.
A New Genus of Hemigobius Generic Group Goby Based on Morphological and Molecular Evidence, with Description of a New Species

Wuhanlinigobius, a new genus of Hemigobius generic group would been established and assigned from Mugilogobius polylepis Wu and Ni, 1985. Mugilogobius polylepis has been regarded as belong to genus Eugnathogobius based on lacking head pores and representing longitudinal sensory papillae in previous taxonomic study. However, we compared the osteological features of Mugilogobius polylepis Wu and Ni, 1985 and Eugnathogobius microps Smith, 1931 as well as the molecular phylogenetic analysis based on the mtDNA ND5, Cyt-b genes and D-loop region. The molecular phylogenetic tree including 9 related Hemigobius generic group reveal that this new genus represents an independent clade which is well separate from other related Hemigobius generic group. The papillae pattern, osteological features and molecular evidence strongly conclude that Eugnathogobius polylepis should be a new genus of Hemigobius generic group, on the other hand, an additional new species of Wuhanlinigobius also will be described herein, and the diagnostic key of this new genus will be provided in this paper.
Addressing pedagogical solitude : a realist evaluation of organisation development at a German higher education institution

To establish a culture of collegial exchange about teaching and learning among its academic staff, a German higher education institution is running a seemingly quite successful organisation development (OD) programme, comprising professional learning communities, conferences and other interventions. But how fit for purpose is the programme? A formative realist evaluation is conducted to establish whether and why the programme works for whom and in what circumstances. On the basis of Coleman’s (1987; 1990) social macro-micro-macro scheme, a programme theory is developed and generalised as a framework for theorising, planning, visualising and evaluating OD. Pawson & Tilley’s (1997) Realistic Evaluation is chosen as research methodology, modified to match the programme theory’s structure and applied to a large data pool covering the OD programme’s first four years. Using an explanatory sequential mixed methods research design involving path analysis, content analysis and realist interviews, the programme theory is tested and gradually refined. The detailed realist evaluation reveals a number of problems at the level of the social mechanisms on which the OD programme’s effectiveness and sustainability depend. Unintended self-selection mechanisms limit the programme’s prospective fitness for purpose. Also the programme’s own history and organisational ramifications interfere with its regular functioning. Various possibilities for improvements are considered and thoughts on the programme’s transferability to other contexts are offered. The thesis concludes with critical reflections on Realistic Evaluation.
Effects of honeybee (apis mellifera) venom on redox balance, biochemical and hematological profile in diabetic rats: A preliminary study

: The treatment of diseases with honeybee venom (apitoxin) is a branch of apitherapy, which has yet to find substantial scientific support. In this present study, we used apitoxin to investigate its effects on diabetes mellitus (DM) in rats. The use of apitoxin injection on single-dose streptozotocin (STZ)-treated rat model was selected, and the study took 28 days. Fasting blood glucose (FBG) was measured weekly. Biochemical and hematological parameters, oxidative stress markers, and insulin levels were measured from the blood samples provided on the last day of the study, and the DNA damage marker (8-OHdG) was measured from urine samples. We found that apitoxin increased malondialdehyde (MDA) and carbonylated protein (PCO), and decreased glutathione (GSH) levels significantly. Additionally, apitoxin increased nitric oxide (NOx) levels significantly in diabetic rats. The findings suggest that apitoxin increases oxidative stress to some extent. Apitoxin had no significant effect on plasma insulin levels. Apitoxin apparently caused small decreases in FBG levels. Apitoxin appears to cause an increase in aspartate aminotransferase (AST), and an increase in the number of platelets (PLT) and granulocytes (GRAN) in diabetic rats. Consequently, the possible antidiabetic effect of apitoxin on DM could only be supported at the preliminary level and presented with speculation in this state of the study. honeybee venom, plasma insulin concentration, redox system, streptozotocin-induced diabetes mellitus
Silicon Integrated Nanophotonic Devices for On-Chip Multi-Mode Interconnects

Mode-division multiplexing (MDM) technology has drawn tremendous attention for its ability to expand the link capacity within a single-wavelength carrier, paving the way for large-scale on-chip data communications. In the MDM system, the signals are carried by a series of higher-order modes in a multi-mode bus waveguide. Hence, it is essential to develop on-chip mode-handling devices. Silicon-on-insulator (SOI) has been considered as a promising platform to realize MDM since it provides an ultra-high-index contrast and mature fabrication processes. In this paper, we review the recent progresses on silicon integrated nanophotonic devices for MDM applications. We firstly discuss the working principles and device configurations of mode (de)multiplexers. In the second section, we summarize the multi-mode routing devices, including multi-mode bends, multi-mode crossings and multi-mode splitters. The inverse-designed multi-mode devices are then discussed in the third section. We also provide a discussion about the emerging reconfigurable MDM devices in the fourth section. Finally, we offer our outlook of the development prospects for on-chip multi-mode photonics.
