Paediatric Analgesia during Inguino-Scrotal Surgery- A Pilot Study

Introduction: There are many different analgesic methods used for children undergoing inguino-scrotal surgery. Research suggests that caudal analgesia reduces the need for postoperative pain relief in these children compared with regional techniques but may increase the risk of motor block and urinary retention. This can be problematic given that these procedures are commonly performed as day cases.
A New Model for Family Owned Business Succession

The Organizational Development (OD) literature has predominantly focused on larger institutions. However, Family Owned Businesses (FOBs) also contribute significantly to the economy and to society. Historically, the success rates of FOB succession are low and questions arise as to the role and importance, if any, of the OD practitioner and scholar in aiding succession planning and transfer within FOBs. This paper explores the existing academic literature on FOB succession, and using the insight gained from assisting FOBs in successful succession, the author merges two existing models on FOB succession to create a new model, thus enhancing our approach to OD interventions in this dynamic field. The new model combines the Integrative Model of Effective FOB Succession (Le Breton-Miller, Miller, & Steier, 2008) and the FOB Knowledge Accumulation Model (Chirico, 2008) in an attempt to adopt the strengths and address the weaknesses of each approach. The effectiveness of this new model is demonstrated through the use of a case study.
Number 11 / 21 A novel model for one-dimensional morphoelasticity . Part I : Theoretical foundations by

While classical continuum theories of elasticity and viscoelasticity have long been used to describe the mechanical behaviour of solid biological tissues, they are of limited use for the description of biological tissues that undergo continuous remodelling. The structural changes to a soft tissue associated with growth and remodelling require a mathematical theory of ‘morphoelasticity’ that is more akin to plasticity than elasticity. However, previously-derived mathematical models for plasticity are difficult to apply and interpret in the context of growth and remodelling: many important concepts from the theory of plasticity do not have simple analogues in biomechanics. In this work, we describe a novel mathematical model that combines the simplicity and interpretability of classical viscoelastic models with the versatility of plasticity theory. While our focus here is on one-dimensional problems, our model builds on earlier work based on the multiplicative decomposition of the deformation gradient and can be adapted to develop a three-dimensional theory. The foundation of this work is the concept of ‘effective strain’, a measure of the difference between the current state and a hypothetical state where the tissue is mechanically relaxed. We develop one-dimensional equations for the evolution of effective strain, and discuss a number of potential applications of this theory. One significant application is the description of a contracting fibroblast-populated collagen lattice, which we further investigate in Part II.
1 Genomics and food production – the social choices

Many scientists think positively about the potential applications of genomics research in the agrofood sector. Thus it is claimed that more knowledge of the plant genome will lead to higher yields because the times for sowing, fertilising and harvesting can be more accurately defined. The same goes for knowledge about resistance to diseases or pests, and crop cultivation in salt-containing or dry soils. Genomics may also influence the processing of agricultural products into foodstuffs. For instance, increased knowledge of micro-organisms may make the transformation of agricultural products into food more efficient and environmentally friendly. Finally an increasing differentiation in food consumption may be achieved because new possibilities exist for the development of ‘custom-made’ nutritional products, those tuned to the specific health requirements of individual consumers. It is expected that, all-in-all, food genomics research will mean choices that will serve many social applications.
A SLUGGS and Gemini/GMOS combined study of the elliptical galaxy M60: wide-field photometry and kinematics of the globular cluster system

We present new wide-field photometry and spectroscopy of the globular clusters (GCs) around NGC 4649 (M60), the third brightest galaxy in the Virgo cluster. Imaging of NGC 4649 was assembled from a recently obtained Hubble Space Telescope/Advanced Camera for Surveys mosaic, and new Subaru/Suprime-Cam and archival Canada–France–Hawaii Telescope/MegaCam data. About 1200 sources were followed up spectroscopically using combined observations from three multi-object spectrographs: Keck/Deep Imaging Multi-Object Spectrograph, Gemini/Gemini Multi-Object Spectrograph and Multiple Mirror Telescope/Hectospec. We confirm 431 unique GCs belonging to NGC 4649, a factor of 3.5 larger than previous data sets and with a factor of 3 improvement in velocity precision. We confirm significant GC colour bimodality and find that the red GCs are more centrally concentrated, while the blue GCs are more spatially extended. We infer negative GC colour gradients in the innermost 20 kpc and flat gradients out to large radii. Rotation is detected along the galaxy major axis for all tracers: blue GCs, red GCs, galaxy stars and planetary nebulae. We compare the observed properties of NGC 4649 with galaxy formation models. We find that formation via a major merger between two gas-poor galaxies, followed by satellite accretion, can consistently reproduce the observations of NGC 4649 at different radii. We find no strong evidence to support an interaction between NGC 4649 and the neighbouring spiral galaxy NGC 4647. We identify interesting GC kinematic features in our data, such as counter-rotating subgroups and bumpy kinematic profiles, which encode more clues about the formation history of NGC 4649.
The classical limit of the Heisenberg and time-dependent Hartree–Fock equations: the Wick symbol of the solution

This paper is concerned with the Wick symbol of time evolving quantum observables. The time dynamics is following either the Heisenberg equation relative to the Schrödinger Hamiltonian, or the time-dependent Hartree–Fock equation. Under very weak assumptions, we prove that the Wick symbol approximatively follows the classical mechanics laws when the semiclassical parameter h tends to zero. For the Heisenberg equation, this is a form of what is commonly called the Ehrenfest theorem. These statements have to be understood in a weaker sense than usual and in return, we do not assume that the Weyl symbol of the initial observable belongs to a class allowing the use of the Egorov theorem. 0. Introduction The aim of this paper is twofold: to prove, under minimal hypotheses, a version of Ehrenfest theorem, and to give a similar result for the time-dependent Hartree– Fock equation (TDHF). We first consider a quantum observable (bounded operator) Ah(t), (t ∈ IR, h > 0), evolving according to the Heisenberg equation associated to the Schrödinger Hamiltonian (see (1.2)). Generally speaking, the Ehrenfest theorem suggests that the average of this observable Ah(t), taken on an h-dependent coherent state, approximatively follows, for small h > 0, the classical mechanics laws [7]. The average of an observable on coherent states is related to its Wick symbol. The first goal of this work is to obtain minimal hypotheses on the initial data Ah(0), in order that the idea conveyed by Ehrenfest is asymptotically verified when h tends to 0. A precise statement of Ehrenfest theorem, using Egorov theorem for the proof, is given in [4, 13] (see also the bibliography therein). It is also noted ([4] and references therein) that the approximation by the classical mechanics laws is not valid uniformly for all time, but up to a maximal time called the Ehrenfest time. These results are obtained assuming that the family of observables (Ah(0)) is a semiclassical pseudodifferential (PDO) operator (see [13] or [17]). Our first goal is therefore to give another precise statement of Ehrenfest theorem, weaker than the one in [13], but in assuming weaker hypotheses on Ah(0) (Theorem 1.1). In particular, we do not assume that Ah(0) is a PDO operator. It is known that an operator in L(IR) is a PDO one in the standard class of Calderón and Vaillancourt, when all its iterated commutators with position and momentum operators are bounded in L(IR) (Beals characterization theorem [2]). In our work, the main assumption is that the single commutators of Ah(0) with position and momentum operators are bounded, without any hypotheses on the iterated commutators. Then we prove that, in some sense, the Received by the editors May 24, 2012.
Foraging behavior of little auks in a heterogeneous environment

The Atlantic sector of the Arctic is currently undergoing large-scale changes in the distribution of water masses in response to the pronounced positive values of the North Atlantic Oscillation. As a consequence the area surrounding little auk Alle alle colonies on Svalbard has experienced an increase in the inflow of Atlantic water. In this study, the influence of water mass dis- tribution on the foraging ecology of little auks was examined through simultaneous measurements made at colonies in Hornsund Fiord (77° 03' N, 15° 10' E) and at sea. In the colony we measured chick diets, while at sea, we assessed the distribution of foraging little auks and the zooplankton available to them within different water masses. Our results indicate that little auks feed mainly on the large copepod Calanus glacialis. They restrict their foraging activity to Arctic water that contains this cope- pod and avoid Atlantic water that contains a smaller copepod, C. finmarchicus. Little auks breeding on Svalbard may be impacted by climate change because during years when the flow of Atlantic water increases, they may be forced to forage in areas with sub-optimal conditions.
Modeling of Two-Wheeled Self-Balancing Robot Driven by DC Gearmotors

Abstract This paper is aimed at modelling a two-wheeled self-balancing robot driven by the geared DC motors. A mathematical model consists of two main parts, the model of robot’s mechanical structure and the model of the actuator. Linearized equations of motion are derived and the overall model of the two-wheeled self-balancing robot is represented in state-space realization for the purpose of state feedback controller design.
Comparison of species richness of light trap-collected caddisfly assemblages (Insecta: Trichoptera) using rarefaction

ConselVation value of light trap-collected caddisfly assemblages(Insecta: Trichoptera) was evaluated on the basis of their species richness. The assemblage coming from an artificial stream showed a higher conservation value based on species richness than the natural ones. In contrast, using rarefaction, the conservation value of the assemblage in the artificial stream was lower in comparison with assemblages in natural habitats. Further examples are given to demonstrate the importance of rarefaction in comparing species richness of assemblages.
SOLVING THE PROBLEM OF VEHICLE ROUTING BY EVOLUTIONARY ALGORITHM

In the presented work the vehicle routing problem is formulated, which concerns planning the collection of wastes by one garbage truck from a certain number of collection points. The garbage truck begins its route in the base point, collects the load in subsequent collection points, then drives the wastes to the disposal site (landfill or sorting plant) and returns to the another visited collection points. The filled garbage truck each time goes to the disposal site. It returns to the base after driving wastes from all collection points. Optimization model is based on genetic algorithm where individual is the whole garbage collection plan. Permutation is proposed as the code of the individual.
Moderate grazing promotes ecosystem carbon sequestration in an Alpine meadow on the Qinghai-Tibetan Plateau.

Grazing could alter plant primary production and carbon (C) storage in Alpine meadow ecosystems. The grazing optimization hypothesis (GOH) suggests that aboveground net primary production increases at a moderate grazing intensity. In this study, GOH was tested by investigating the responses of plant production and ecosystem C storage to grazing intensity. The results indicated that both the root biomass and total biomass reached the highest values in moderate grazing (MG), and the species richness, root to shoot ratio (R:S ratio) increased in MG, suggesting that more assimilates allocated from aboveground to belowground under MG. Similar plant material carbon concentrations were observed for all of the grazing intensities (i.e. , 40-50%), and the soil organic carbon (SOC) storage depended on the root biomass. The soil organic C storage and ecosystem C storage both peaked with MG, which supported GOH. Thus, moderate grazing promoted ecosystem C sequestration by altering the plant community structure, plant production and R:S ratio in the Alpine grassland.
Phytochemical Screening and Antimicrobial Evaluation of Syzygium aromaticum Extract and Essential oil

Spices and herbs have been used for thousands of centuries by many continents to enhance the flavor and aroma of foods; preserving foods and for their medicinal value. Spices are aromatic plant products which are frequently used to enhance food palatability. Most spices were originally indigenous to the tropics eg. cinnamon, pepper, clove and nutmeg (Viuda-Martos et al., 2007). Syzygium aromaticum (Clove bud) is one of the most ancient and valuable spices of the Orient (Chaieb et al., 2007) which are used as a carminative to increase hydrochloric acid in the stomach and to improve peristalsis.

Very Fast Money: High-Frequency Trading on the NASDAQ

This paper provides evidence regarding high-frequency trader (HFT) trading performance, trading costs, and effects on market efficiency using a sample of NASDAQ trades and quotes that directly identifies HFT participation. I find that HFTs engage in successful intra-day market timing, spreads are wider when HFTs provide liquidity and tighter when HFTs take liquidity, and prices incorporate information from order flow and market-wide returns more efficiently on days when HFT participation is high.
Psychodiagnostic and Psychotherapeutic Judgments: Expectation-Based Biases in Covariation Assessment.

ABSTRACT This paper considers three clinical judgment biases in clinical inference: (1) illusory correlation bias, the report by clinicians of a correlation between psychodiagnostic test signs and patient's symptoms which are not correlated or are correlated to a smaller degree than that reported; (2) labeling hies, the tendency of exposure to diagnositc labels to influence clinician's inferences about patients in such a way as to confirm the original label in the clinician's diagnosis; and (3) therapy outcome bias, the clinicians' belief that therapeutic, techniques toward which they are favorably predisposed are more effective in remediating patients' symptoms than are alternative treatment strategies, even when research has shown that their favored strategies have no advantage over alternative therapies. Alloy and Tabachnik's theoretical model for understanding people'r covariation assessments is applied to clinicians' diagnostic and therapy decisions in an attempt to formulate a covariation perspective for understanding clinical judgments. Evidence is presented which demonstrates that clinicians' judgments are influenced jointly by expectations and situational information. It is argued that often when covariation judgments go awry, they have been biased by clinicians' a priori expectations. The implications of the illusory correlation, labeling, and therapy outcome biases for clinical practice are considered, and the issues of accuracy, rationality, and utility in evaluating the impact of such biases are discussed. Possible strategies for debiasing inaccurate diagnostic and therapeutic inferences are suggested. (NRB)
Comparing Tropospheric Warming in Climate Models and Satellite Data

AbstractUpdated and improved satellite retrievals of the temperature of the mid-to-upper troposphere (TMT) are used to address key questions about the size and significance of TMT trends, agreement with model-derived TMT values, and whether models and satellite data show similar vertical profiles of warming. A recent study claimed that TMT trends over 1979 and 2015 are 3 times larger in climate models than in satellite data but did not correct for the contribution TMT trends receive from stratospheric cooling. Here, it is shown that the average ratio of modeled and observed TMT trends is sensitive to both satellite data uncertainties and model–data differences in stratospheric cooling. When the impact of lower-stratospheric cooling on TMT is accounted for, and when the most recent versions of satellite datasets are used, the previously claimed ratio of three between simulated and observed near-global TMT trends is reduced to approximately 1.7. Next, the validity of the statement that satellite data show n.

Estimation of signal attenuation in the 60 GHZ band with an analog BiCMOS passive filter

Prediction of millimeter(mm)-wave radio signals can be beneficial in recreating and repeating atmospheric conditions in a controlled, laboratory environment. A path-loss model has been proposed that accounts for free-space losses, oxygen absorption, reflection and diffraction losses, and rain-rate attenuation at mm-wave frequencies. Two variable passive low-pass-integrated circuit filter structures for attenuation in the 57–64 GHz unlicensed frequency band have been proposed, designed, simulated, prototyped in a 130-nm SiGe bipolar complementary metal-oxide semiconductor process, and measured. The filters are based on the Butterworth and Chebyshev low-pass filter topologies and investigate the possibility of using the structures to perform amplitude attenuation of mm-wave frequencies over a short distance. Both filters are designed and matched for direct coupling with equivalent circuit models of dipole antennas operating in this frequency band. Full integration therefore allows prediction of atmospheric losses on an analog, real-time, basis without the requirement of down-converting (sampling) to analyze high-frequency signals through a digital architecture. On-wafer probe measurements were performed to limit parasitic interference from bonding wires and enclosed packaging.
Teaching and Learning Economics through Cinema

In July 2006 the author and a small team of colleagues received funding from the Economics Network of the Higher Education Authority to enable the development of a new module which aims to teach economics through the arts, in particular through the use of cinema and literature . The idea of teaching economics with cinema is not new, and is practiced in a number of educational institutions in the United States. The approach used in that country is, however, quite different from the one proposed here and used in the pilot study. In the United State, modules are usually run in the students’ first year presenting a variety of fundamental economic concepts such as opportunity cost, scarcity, aymmetric information and illustrating them using films (see, for example, Leet and Houser (2003)). The approach developed here is, in a sense, the reverse of that process since it is the medium of cinema which is allowed to inform and suggest the economic concepts that can be discussed through this medium. As a consequence, the range of topics covered is much wider and the approach also allows coverage of unconventional topics such as the economics of charities, dowries and the economics of crime.
AGN/Starburst Connection

Two main physical processes characterize the activity in the nuclear region of active galaxies: an intense star formation (starburst, SB) and an Active Galactic Nucleus (AGN). While the existence of a starburst-AGN connection is undisputed, still it is not clear which process dominates the energetic output in both local and high redshift Universe. Moreover there is no consensus on whether AGN fueling is synchronous with star formation or follows it during a post-starburst phase. Here I first review how to disentangle the relative SB-AGN contribution, then I focus on the physical and geometrical properties of the circumnuclear environment.
