Tracer interrelationships in the stratosphere

Relationships between long‐lived stratospheric tracers, manifested in similar spatial structures on scales ranging from a few to several thousand kilometers, are displayed most strikingly if the mixing ratio of one is plotted against another, when the data collapse onto remarkably compact curves. Distinct curves form in the polar vortex, the midlatitude “surf zones”, and the tropics. Theory predicts such relationships for sufficiently rapid mixing along isentropic surfaces. Model results are used to illustrate the formation and seasonal evolution of distinct tracer relationships in the different regions. Using such relationships to associate departures from canonical forms with anomalous chemical or microphysical behavior must be done with care and with full awareness of the meteorological context of the data. Although the theory has been developed in the context of stratospheric tracers, the key requirement is that transport is predominantly two‐dimensional. While the theory is thus inappropriate in the troposphere, it should be applicable to transport in the ocean interior.
Development and Evaluation of an Axial Gap Motor Using Neodymium Bonded Magnet

In general, radial gap motors employing neodymium sintered permanent magnet (Nd sintered PM) are used to achieve high torque density in many applications. However, the motors are not suited to a flat, disk-like shape because the dead space, such as the coil ends, occupies most of the motor volume. Therefore, axial gap motors are frequently used for flat shape instead of radial gap motors. Nd sintered PM is a well-known high-performance magnet that has high residual magnetic flux density, but eddy current loss easily occurs in the magnet because of its high conductivity. In axial gap motors for industrial applications, it is difficult to take measures against eddy current loss of Nd sintered PM in terms of cost. Therefore, general axial gap motors employing Nd sintered PM often have unsatisfactory characteristics, such as low efficiency, even though the motor produces high torque. On the other hand, radial gap motors can take measures to suppress eddy current in PMs easily if radial gap motors employ interior permanent magnet structure. Accordingly, this paper discusses an axial gap motor employing neodymium bonded permanent magnet (Nd bonded PM) for flat shape. Compared with Nd sintered PM, Nd bonded PM has lower residual magnetic flux density, but also lower cost. In addition, Nd bonded PM has extremely low eddy current loss due to its low conductivity. It is found from three-dimensional finite element analysis and experimental results that the axial gap motor employing Nd bonded PM can achieve higher torque and higher efficiency compared with the radial gap motor employing Nd sintered PM with the same PM weight and a flat shape.
Prioritizing water supply infrastructure investments in Sri Lanka : an application of the world bank infrastructure prioritization framework

Governments are challenged to balance multiple policy goals and make difficult choices when selecting infrastructure projects for public investment, particularly since available funds are often insufficient to implement the full suite of proposals. This paper presents the application of the Infrastructure Prioritization Framework, a systematic, multi-criteria approach to infrastructure project prioritization, to inform the selection of water supply investments in Sri Lanka. A set of 28 proposed water supply projects was prioritized at the request of the National Planning Department of Sri Lanka, based on consideration of multiple goals, including improved water quality and service, network extension, service provision to poor communities, job creation, and sound financial performance. This paper reviews the Infrastructure Prioritization Framework methodology; presents the results of the prioritization exercise, including an expanded sensitivity analysis; and discusses the way forward to apply the Infrastructure Prioritization Framework to inform infrastructure investment decisions.
HEALING AND THERAPEUTIC LANDSCAPE DESIGN – EXAMPLES AND EXPERIENCE OF MEDICAL FACILITIES

Healing and therapeutic landscape design proposals are particularly suitable for medical facilities and, in general, facilities for people with health disorders, where they become a major support in difficult situations and can serve as a supplement to treatment. They do not replace medical help and different therapies, and neither do they exclude their need. However, their effects can improve and accelerate the recovery process in patients. In Slovakia, medical facilities do not often meet modern medical care requirements in terms of their technologies and equipment. For this reason, it is necessary to mainly transform hospital facilities and their exteriors in order to create the required natural foundation for patients in the form of healing and therapeutic landscape design. Using the example of the Philippe Pinel Psychiatric Hospital in Pezinok (Slovakia, Central Europe), we present a proposal for a green vegetation-scaping using the existing space, adding elements that highlight and support the therapeutic effect of the proposed space. The aim of the proposal is to create an environment that will bring positive changes for patients while serving as a relaxation space for employees.
RFID and Returnable Transport Items Management: An Activity-based Model to Assess the Costs and Benefits in the Fruit and Vegetable Supply Chain

Radio Frequency Identification (RFId) technology promises to enable substantial benefits in Returnable Transport Items management. Lured by this opportunity, some companies (e.g. Metro Group) are carrying out pilot projects, but the difficulties in quantifying the costs and benefits stemming from such applications still prevent many companies from using this technology. This paper describes an analytical model to assess the profitability of such investments, focusing on the fruit and vegetable supply chain.
A resource-based view perspective on Lean Production: a case study

The Resource Based View and Lean Production focus upon value, efficiency and waste. The RBV sees firms with superior systems and structures being profitable because they have lower costs, higher quality and superior products. Lean implementation reduces cost, whilst improving quality and delivery performance, which increases customer value. A case study at SteelCo explains the implementation of Lean in terms of a resource based perspective. SteelCo’s knowledge of pipe making was combined with external knowledge of Lean Production. The team-based problem solving approach improved processes, shaped culture and helped develop a learning organisation. When a Lean philosophy had become embedded within the organisation, a process of continuous improvement generated new resources and capabilities. The Lean implementation increased productivity by 50%.
Numerical methods for plasma physics in collisional regimes

We consider the development of accurate and efficient numerical methods for the solution of the Vlasov–Landau equation describing a collisional plasma. The methods combine a Lagrangian approach for the Vlasov solver with a fast spectral method for the solution of the Landau operator. To this goal, new modified spectral methods for the Landau integral which are capable to capture correctly the Maxwellian steady state are introduced. A particular care is devoted to the construction of Implicit–Explicit and Exponential Runge–Kutta methods that permit to achieve high-order and efficient time integration of the collisional step. Several numerical tests are reported which show the high accuracy of the numerical schemes here presented.
Low latency demodulation for Atomic Force Microscopes, Part I efficient real-time integration

This paper describes methods for doing high speed, low latency, coherent demodulation of signals for dynamic or AC mode in Atomic Force Microscopes (AFMs) [1]. These demodulation methods allow the system to extract signal information in as little as one cycle of the fundamental oscillation frequency. By having so little latency, the demodulator minimizes the time delay in the servo loop for an AC mode AFM. This in turn minimizes the negative phase effects of the demodulation allowing for higher speed scanning. This part of the paper describes the mixing and integration portion of the demodulator. Part II [2] describes efficient methods for extracting magnitude and phase in real time.
Cross-cultural Boundary Dilemmas: A Graded-risk Assessment Approach

Behavioral health professionals are constantly faced with the dilemma of how to define boundaries in their relationships with clients. When working with groups from diverse cultures, defining boundaries becomes even more complex. This article urges a flexible approach, using the graded-risk model (Martinez, 2000) and a list of cultural factors for clinicians to consider. Possible benefits of reaching out to clients in concrete ways, as well as risks, are emphasized. Clients’ notions of appropriate boundaries must be considered in the decision-making process. Case examples from a refugee mental health clinic are used to elucidate a flexible approach to boundary decisions.
Ovarian mucinous tumour arising in mature cystic teratoma and associated with pseudomyxoma peritonei: report of two cases and comparison with ovarian involvement by low‐grade appendiceal mucinous tumour

Aims: It is currently accepted that primary ovarian tumours rarely, if ever, give rise to mucinous ascites/pseudomyxoma peritonei (PMP) which most commonly results from the intra‐abdominal spread of an appendiceal mucinous neoplasm. However, primary ovarian mucinous tumours of appendiceal type arising within mature cystic teratomas appear to represent an exception to this rule. In this report two further examples of this rare tumour are described, and the immunohistological phenotype including expression of MUC proteins is compared with secondary ovarian involvement by low‐grade appendiceal mucinous neoplasm. Methods: Two cases of ovarian mucinous tumour associated with mature cystic teratoma and PMP are described. The tumours were examined immunohistochemically for expression of cytokeratin (CK)7, CK20, carcinoembryonic antigen (CEA), CDX‐2, MUC2, MUC5AC and MUC6. The results were compared with four cases of ovarian neoplasia secondary to primary appendiceal low‐grade mucinous tumour. Results: The ovarian mucinous tumours associated with mature cystic teratomas were morphologically similar to those secondary to appendiceal neoplasia. They comprised irregularly distributed glands and cysts lined by tall, mucin‐rich epithelial cells exhibiting focal villoglandular architecture and low grade cytological atypia. The immunophenotype of the teratoma‐associated tumours and those secondary to appendiceal neoplasia was identical: there was strong and diffuse expression of CK20, CEA, CDX‐2, MUC2 and MUC5AC with no reactivity for the other antisera tested. Conclusions: PMP associated with primary ovarian neoplasia is rare, and probably restricted to mucinous tumours arising in mature cystic teratomas. The immunohistological findings in this study further support the view that such tumours exhibit a lower gastrointestinal and, more specifically, appendiceal phenotype. Careful examination and sampling of the ovaries may be required to demonstrate the teratomatous component of these tumours.
Glutamine Administration Modulates Lung &ggr;&dgr; T Lymphocyte Expression in Mice With Polymicrobial Sepsis

ABSTRACT This study investigated the effects of glutamine (GLN) administration on regulating lung &ggr;&dgr; T cells in polymicrobial sepsis. Mice were randomly assigned to normal group (NC), septic saline group (SS), and septic GLN group (SG). All mice were fed with chow diet. Sepsis was induced by cecal ligation and puncture (CLP). The SS and SG groups were, respectively, injected with saline and 0.75 g GLN/kg body weight once via tail vein 1 h after CLP. Mice were killed 12 and 24 h after CLP. Their lungs were collected for further analysis. The results showed that, compared with normal mice, sepsis resulted in higher lung &ggr;&dgr; T cell and neutrophil percentages and higher cytokine expressed by &ggr;&dgr; T cells. Histopathologic findings showed that the extent of inflammatory lesions of the lung alveolar was less severe in the SG group than the SS group after CLP. The SG group had a higher &ggr;&dgr; T cell percentage and lower &ggr;&dgr; T cell apoptotic rates as well as lower neutrophil numbers in the lungs. Also, interleukin 17A (IL-17A), interferon &ggr;, and IL-10 expressed by &ggr;&dgr; T cells and CXC receptor 2 expressed by neutrophils decreased in the SG group. Moreover, GLN reduced IL-17A, IL-1&bgr;, and IL-23 concentrations and myeloperoxidase activity in lung tissues. Our results suggest that GLN administration after initiation of sepsis affects lung &ggr;&dgr; T cell percentage and cytokine secretion and prevented apoptosis of &ggr;&dgr; T cells and neutrophil infiltration to the lungs, which may partly be responsible for ameliorating acute lung injury induced by sepsis.
Magnetic Fields in the Formation of Sun-Like Stars

We report high-angular-resolution measurements of polarized dust emission toward the low-mass protostellar system NGC 1333 IRAS 4A. We show that in this system the observed magnetic field morphology is in agreement with the standard theoretical models of the formation of Sun-like stars in magnetized molecular clouds at scales of a few hundred astronomical units; gravity has overcome magnetic support, and the magnetic field traces a clear hourglass shape. The magnetic field is substantially more important than turbulence in the evolution of the system, and the initial misalignment of the magnetic and spin axes may have been important in the formation of the binary system.
Analysis and design of an isolated single-stage converter achieving power-factor correction and fast regulation

This paper presents the analysis and design of an isolated single-stage converter achieving high-power-factor correction and fast regulation. By using the technique suggested by Wu et al., a buck-boost converter and a flyback converter can be integrated to form the discussed converter. The buck-boost semistage working in the discontinuous conduction mode (DCM) functions as a power-factor corrector, and the flyback semistage operating in the DCM is a voltage regulator which is controlled, theoretically, to be independent of load variation. An approximated small-signal model of the converter operating in the DCM is developed. Design of a peak-current feedback loop with an optimal proportional integral controller is also presented. A prototype is implemented to verify that the analysis and design are effective and feasible.
Towards a Multidimensional Model to Study a Critical Success Factors Affecting Continuity and Success in E-Learning Systems

E-learning constitutes an alternative to face to face traditional educational system. Unfortunately, many learners stop their online learning at its beginning. This paper aims system at exploring and identifying the critical success factors (CSFs) to predict learners' satisfaction, continuance and success in on line platform learning. We also proposed a hybrid model that classify success factors of online learning in four dimensions include the learner characteristics, the instructor characteristics, the system specificities and the social influence
Effect of Metformin or Gliclazide on Lipid Peroxidation and Antioxidant Levels in Patients with Diabetes Mellitus

Materials and Methods: In this study, we evaluated 46 patients with type 2 diabetes mellitus. The patients were divided into three groups according to their treatment modality of gliclazide, metformin, or diet. Erythrocyte glutathione peroxidase (Gpx), glutathione S-transferase (GST), and catalase (CAT) activities and malondialdehyde (MDA) and glutathione (GSH) levels of the patients were measured and compared. Results: The erythrocyte Gpx, GST, and CAT activities were significantly higher, whereas MDA levels were significantly lower in both gliclazide and metformin groups when compared with the diet group. There was no statistically significant difference between gliclazide and metformin groups in terms of activities of antioxidant enzymes and levels of MDA. In addition, GSH levels were not different among the groups. Conclusions: The data obtained in this study showed that gliclazide or metformin administration may decrease oxidative stress, and both drugs had similar effects.

The $^8$Li$(n,\gamma)$$^9$Li reaction plays a critical role in several reaction chains leading to the nucleosynthesis of $A>12$ nuclei. Due to unstable nature of $^8$Li and the unavailability of neutron targets, direct measurements of this reaction are exceedingly difficult. Only upper limits of this cross section, provided by the indirect experiments, have been obtained so far. In this work, we use the Gamow shell model (GSM) in the coupled-channel representation (GSM-CC) to study the properties of $^9$Li and the radiative capture reaction $^8$Li$(n,\gamma)$$^9$Li. In GSM-CC calculations, a translationally invariant Hamiltonian is used with a finite-range two-body interaction tuned to reproduce the low-energy spectra of $^{8-9}$Li. In the calculation of $^8$Li$(n,\gamma)$$^9$Li cross section, all relevant E1, M1, and E2 transitions from the initial continuum states to the final bound states ${3/2}_1^-$, ${1/2}_1^-$ and the resonance ${5/2}_1^-$ of $^9$Li are included. The GSM-CC approach reproduces the experimental low-energy spectrum, neutron emission threshold, and spectroscopic factors in $^9$Li. The calculated reaction rate is consistent with the experimental upper limit of the reaction rate obtained in the indirect measurements at stellar energies. The GSM-CC calculations suggest that the $^8$Li$(n,\gamma)$$^9$Li reaction can reduce heavy-element production via the main chain $^7$Li($n,\gamma$)$^8$Li($\alpha,n$)$^{11}$B($n,\gamma$)$^{12}$B($\beta^+$)$^{12}$C. Major contribution to the calculated cross section is given by the direct E1 transition to the ground state of $^8$Li. The contribution of excited states to the reaction rate does not exceed $\sim$18% of the total reaction rate.
Streptozotocin dose-response curve in tilapia, a glucose-responsive teleost fish.

Streptozotocin (STZ) causes beta cell necrosis and insulin-dependent diabetes in many species. The specificity of this beta cell toxin relates to its structure as an alkylating agent with an attached glucose moiety. STZ uptake by rodent beta cells appears to be via the GLUT-2 glucose transporter. Teleost fish, in general, are severely glucose intolerant. The effects of STZ were examined in tilapia, a teleost fish with highly glucose-responsive islets. Fasted tilapia were given 0, 100, 150, 200, 250, 300, or 350 mg/kg STZ iv. Plasma glucose levels were followed for 72 h and the fish autopsied. Histological sections of islets were stained by immunoperoxidase for tilapia insulin. Severe hyperglycemia was seen in 20, 80, and 100% of fish receiving 250, 300, and 350 mg/kg doses; however, sections of islets showed only partial degranulation with no evidence of beta cell necrosis. Another group of fish receiving the highest dose were followed longer to determine whether beta cell necrosis and permanent hyperglycemia ensued. All fish died or were killed within 9 days because of severe hepatic failure characterized by hepatic necrosis, jaundice, and ascites; islet morphology was relatively normal suggesting, even in a glucose-sensitive species, that fish islets either do not take up STZ or are highly resistant to its "diabetogenic" effects. Tilapia may thus be a useful model to elucidate mechanisms of action of STZ. Furthermore, STZ may provide important insights into differences in glucose uptake and metabolism by mammalian and piscine beta cells.
Applications of Optical Current and Voltage Sensors in High-Voltage Systems

Various applications of optical current and voltage sensors are explored. Wide bandwidth, linearity, high accuracy, and light weight of these sensors make this technology suitable for numerous applications: high-accuracy wide dynamic range revenue metering, regular protection applications, capacitor bank unbalance protection (low ratio CTs), current measurement in HVDC systems, and power quality monitoring including measurement of harmonics near static VAR compensators and fast transient measurements. The fiber optic CT with a unique flexible head packaging (rope-shaped wrap-around sensor head) has novel application in generator monitoring and protection. Due to their light weight and ease of deployment, both the flexible-head optical CT and the optical VT are great tools as portable calibration systems for live in-situ calibration and monitoring applications
Corporate governance and audit fees: Evidence from a developing country

In this paper, we investigate the effect of board and audit committee quality on the audit fees in the context of developing country of Pakistan. We us five years data of KSE-100 index companies listed on Pakistan Stock Exchange. To draw the inference, we use the Partial Least Square based Structural Equation Modeling. We find that effective board quality (measured through board size, board independence, CEO duality, chairperson independence, board equity holding, and board diligence) is positively associated with external auditor fees. This finding suggests that, high quality board demands higher quality audit to have further assurance on the quality of financial reporting. While, we find audit committee effectiveness (measured through audit committee size, audit committee independence, and audit committee diligence) reduces the external audit fee, which supports our notion that, the high quality audit committee will ensure reliable financial reporting which reduces external auditor’s efforts that result in lower audit fees.
