Published: September 2014

We measured nutrient distribution of Picea likiangensis (Franchet) E. Pritzel var. balfouriana trees growing in a plantation by field investigations, sample tree and plot harvest in West Sichuan, Southwest China. Based on the results in this study, the total biomass of plant compartments in plantation ecosystem was 114Â 829.1 kg haâ1. Tree, shrub, herb, bryophyte and litter layers accounted for 93.9%, 0.9%, 0.02%, 0.04%, 5.2%, respectively. The total biomass of tree layers was 107Â 817.1 kg haâ1. Needles, branches, stem wood, stem bark and roots accounted for 13.2%, 19.7%, 42.3%, 10.0% and 14.8%, respectively. The concentration of the nutrients was generally highest in the actively growing parts of the trees (e.g. needles) and lowest in the structural and not actively growing parts (e.g. stem wood). On the other hand, the concentrations of N, P, K and Mg were generally higher in the current year needles and branches than in the older needles and branches. These nutrient concentrations were also higher in the upper stem wood and bark than in the lower stem wood and bark, and in small roots than in large roots, whereas the opposite patterns were observed for the concentration of Ca in these compartments. The results will be helpful in understanding the nutrient behavior in a highly productive forest plantation and thereby providing decisive information for their sustainable management.

AbstractOnly a limited number of cytotoxic drugs have shown activity in metastatic colorectal carcinoma. Patupilone is a novel agent with promising activity in this common cancer. Diarrhea represents the dose-limiting toxicity of patupilone. Measurement of intestinal permeability is one of the potential methods of non-invasive laboratory assessment of gastrointestinal toxicity.We have assessed intestinal permeability by measuring absorption of lactulose, mannitol and xylose in 27 previously treated patients with metastatic colorectal cancer enrolled in a phase I trial of patupilone.Lactulose/mannitol and lactulose/xylose ratios increased after the treatment. Significantly higher lactulose/mannitol ratio was observed in patients who had severe diarrhea. Moreover, patients who subsequently had an adverse event of grade 3 or higher had significantly higher baseline lactulose/mannitol or lactulose/xylose ratios.Measurement of intestinal permeability using the lactulose/mannitol test may represent a biomarker for the monitoring, or even prediction of toxicity of cytotoxic drugs, including patupilone.

AbstractThe interaction of light and sound waves at the micro and nanoscale has attracted considerable interest in recent years. The main reason is that this interaction is responsible for a wide variety of intriguing physical phenomena, ranging from the laser-induced cooling of a micromechanical resonator down to its ground state to the management of the speed of guided light pulses by exciting sound waves. A common feature of all these phenomena is the feasibility to tightly confine photons and phonons of similar wavelengths in a very small volume. Amongst the different structures that enable such confinement, optomechanical or phoxonic crystals, which are periodic structures displaying forbidden frequency band gaps for light and sound waves, have revealed themselves as the most appropriate candidates to host nanoscale structures where the light-sound interaction can be boosted. In this review, we describe the theoretical tools that allow the modeling of the interaction between photons and acoustic phonons in nanoscale structures, namely cavities and waveguides, with special emphasis in phoxonic crystal structures. First, we start by summarizing the different optomechanical or phoxonic crystal structures proposed so far and discuss their main advantages and limitations. Then, we describe the different mechanisms that make light interact with sound, and show how to treat them from a theoretical point of view. We then illustrate the different photon-phonon interaction processes with numerical simulations in realistic phoxonic cavities and waveguides. Finally, we introduce some possible applications which can take enormous benefit from the enhanced interaction between light and sound at the nanoscale.
Forced Displacement in Colombia: What Determines Expulsion and Reception in Municipalities?
Authors: Dueñas Ximena , Palacios Paola , Zuluaga Blanca 
Published: September 2014

AbstractThis document explores the expulsion and reception determinants of displaced people among Colombian municipalities. For this purpose, we use fixed effects panel data estimations for the period 2004–2009, with municipality year as the unit of analysis. To the best of our knowledge, this is the first paper in Colombia that focuses on reception and the first one using panel data at municipal level to explain expulsion and reception. We find that, contrary to what one may expect, some independent variables affect both expulsion and reception of displaced people in the same direction; for instance, municipalities where homicide rates and conflict intensity are high, are associated with both higher reception and expulsion rates. In addition to the conventional panel data estimation, we also run a fixed effect vector decomposition to identify the explicit effects of certain time-invariant variables.

Physician health and wellness is a critical issue gaining national attention because of the high prevalence of physician burnout. Pediatricians and pediatric trainees experience burnout at levels equivalent to other medical specialties, highlighting a need for more effective efforts to promote health and well-being in the pediatric community. This report will provide an overview of physician burnout, an update on work in the field of preventive physician health and wellness, and a discussion of emerging initiatives that have potential to promote health at all levels of pediatric training.
Pediatricians are uniquely positioned to lead this movement nationally, in part because of the emphasis placed on wellness in the Pediatric Milestone Project, a joint collaboration between the Accreditation Council for Graduate Medical Education and the American Board of Pediatrics. Updated core competencies calling for a balanced approach to health, including focus on nutrition, exercise, mindfulness, and effective stress management, signal a paradigm shift and send the message that it is time for pediatricians to cultivate a culture of wellness better aligned with their responsibilities as role models and congruent with advances in pediatric training.
Rather than reviewing programs in place to address substance abuse and other serious conditions in distressed physicians, this article focuses on forward progress in the field, with an emphasis on the need for prevention and anticipation of predictable stressors related to burnout in medical training and practice. Examples of positive progress and several programs designed to promote physician health and wellness are reviewed. Areas where more research is needed are highlighted.

Abstract
This study provides the preliminary report about first occurrence of orthorhombic 11C pyrrhotite (Fe(1-x)S) from the Sudetes, Poland. Samples of pyrrhotite-containing two-pyroxene gabbro were found in a classic pegmatite locality in Michałkowa near Walim in the Góry Sowie Block. Based on microscopic methods, pyrrhotite is associated with pentlandite, chalcopyrite, chromite, ilmenite, gersdorffite, magnetite, biotite, magnesiohornblende, clinochlore, lizardite and talc. X-Ray diffraction (XRD) indicate that pyrrhotite has orthorhombic 11C structure and it is characterized by: a = 3.433(9) Å, b = 5.99(2) Å, c = 5.7432(5) Å, β = 90º and d102 = 2.06906 Å. Mössbauer studies confirmed the XRD data. Pyrrhotite has three sextets with hyperfine parameter values 30.8 T for sextet A, 27.9 T and 25.8 T for sextets B and C respectively, indicating orthorhombic structure, the composition near Fe10S11 and x = 0.0909

A Comprehensive Mathematical Programming Model for Minimizing Costs in A Multiple-Item Reverse Supply Chain with Sensitivity Analysis
Authors: Mahmoudi Hoda , Fazlollahtabar Hamed 
Published: September 2014

Abstract
These instructions give you guidelines for preparing papers for IFAC conferences. A reverse supply chain is configured by a sequence of elements forming a continuous process to treat return-products until they are properly recovered or disposed. The activities in a reverse supply chain include collection, cleaning, disassembly, test and sorting, storage, transport, and recovery operations. This paper presents a mathematical programming model with the objective of minimizing the total costs of reverse supply chain including transportation, fixed opening, operation, maintenance and remanufacturing costs of centers. The proposed model considers the design of a multi-layer, multi-product reverse supply chain that consists of returning, disassembly, processing, recycling, remanufacturing, materials and distribution centers. This integer linear programming model is solved by using Lingo 9 software and the results are reported. Finally, a sensitivity analysis of the proposed model is also presented.

Abstract

Background and Aims: Resting metabolic rate (RMR) is important to estimate energy requirements. Our aim was to investigate the RMR in newly diagnosed type 2 diabetic (T2DM) patients with metabolic syndrome (MS) in relation with obesity, gender, some adipokines and insulin resistance parameters. Material and Methods: 138 newly diagnosed T2DM adults were evaluated for anthropometric, clinical, biochemical parameters, and RMR. The group was subdivided according to body mass index and MS presence. Results: Determined RMR (RMRd), predicted RMR (RMRp), oxygen consumption and carbon dioxide production at rest were significantly lower for subjects with BMI < 30 kg/m2 compared to subjects with BMI ≥ 30 kg/m2 (p<0.001). RMRd positively correlated with fat-free mass (p < 0.001), waist (p < 0.001), BMI (p < 0.001), insulinemia (p = 0.021) and negatively with age (p < 0.001) and adiponectin (p = 0.027). The percent of determined from predicted RMR in subjects with MS was lower than in those without MS, but only for men (p< 0.005). Conclusions: Subjects with T2DM and MS have significantly lower than predicted RMR, compared to those without MS, indicating that they may have an energy sparing metabolism. Gender influences the energy metabolism and may play a particular role in energy the metabolism of people with T2DM and MS.

Abstract

Background and Aims: Diabetes mellitus (DM) is a chronic disease which can evolve towards devastating micro and macro-vascular complications. Chronic kidney disease (CKD) is a worldwide public health problem, with adverse outcomes of kidney failure, cardiovascular disease (CVD) and premature death. The aim of our study was to evaluate the prognosis in patients with DM and CKD, depending on estimated glomerular filtration rate (eGFR) and albuminuria, according to the classification of Clinical Practice Guideline for the Evaluation and Management of Chronic Kidney Disease (KDIGO) from 2013 Materials and Methods: The study was epidemiological, transversal, non interventional type, with 600 subjects unselected patients divided into three subgroups: 200 patients with T1DM, 200 patients with T2DM and 200 age matched subjects without DM. The recorded data have been analyzed using the Statistic Package for Social Sciences (SPSS), the 17.00 software (IBM Corporation, Armonk, NY, United States of America). Results:. We found a statistically significant difference among the three study groups (p < 0.0001) regarding the prognosis of CKD. Conclusions: DM represents an important risk factor for the appearance of CKD but also a negative prognosis factor for the patients with CKD.

Abstract
Parenteral nutrition (PN) represents an alternative or additional approach when other nutrition routes are not succeeding or when using other routes is not possible or would be unsafe. The main goal of PN is to deliver a nutrient mixture closely related to requirements in a safe manner and without complications. The concentration of parenteral solutions (PS) determines their osmolarity, according to which, the solutions will be infused by peripheral or central venous access. The solutions used in central PN contain more glucose, which, together with amino acids and electrolytes, determines a hyperosmolar solution, which has to be administered in a large caliber vein. Central venous access may be maintained over long periods of time. In peripheral PN there are used solutions with a lower concentration of dextrose in order to obtain (solutions with the) an osmolarity lower than 900 mOsm/L, which can be administered in a peripheral vein. Peripheral PN is used over short periods of time because of the limited tolerance for a long term of peripheral veins. PN is an efficient method to ensure the nutritional support which can be associated with numerous complications, some of them severe, with lethal potential. Patients with PN need a daily physical examination and laboratory tests.

Radiological diagnosis of rectocutaneous fistulas in a cat - a case report
Authors: Łojszczyk-Szczepaniak Anna , Komsta Renata , Dębiak Piotr , Barbara Lisiak 
Published: September 2014

Abscess and perirectal fistulas are common in humans but not so in animals. Fistulas located in tissues surrounding the anus are usually described in the course of furunculosis in dogs. This study presents the case of a one-year-old cat in which two rectocutaneous fistulas had formed. This process was a result of the chronic inflammation of tissues around the base of the tail due to the drainage of an abscess. The animal was referred for radiological examination with clinical signs of dyschezia. Faecal material was discharged only through the fistulas situated on both sides of the tail. The aim of the radiological examination was to preoperatively determine the course of the fistula tract and to identify their internal openings. Fistulography revealed that both fistulas were connected with each other and with the rectal lumen. Their external opening was located at the height of the 4th caudal vertebra, 1.5 cm (fistula on the right) and 2 cm (fistula on the left) from the wall of the rectum. The fistula located on the right side branched cranially. The rectal lumen in this area was significantly narrowed. Abscess formation resulting in the development of rectocutaneous fistulas has not yet been described in dogs or cats. In the present case, fistulography made it possible to identify directly the source and course of the fistula canal. This examination should be complemented by other diagnostic modalities, such as a contrast examination of the gastrointerstinal tract, ultrasound evaluation, and magnetic resonance imaging.

Published: September 2014

Abstract
This work studies the effects of Zn/Cu ratio and silicon on the improvement of mechanical properties, tarnish and corrosion resistance of 940 silver alloys. The silver alloys to be investigated are divided into 2 groups. The group 1 alloys are Ag-Cu-Zn alloys. The group 2 alloys are Ag-Cu-Zn-0.02Si alloys. The microstructures of all alloys to be tested look similar and consist of a Ag-rich matrix (α phase) and Cu-rich eutectic structure (α + β phase). The proportion of eutectic structure decreases by increasing Zn/Cu ratio. Increasing Zn/Cu ratio significantly decreases hardness, ultimate tensile strength, but markedly increases elongation. Addition of 0.02wt.- %Si to Ag-Cu-Zn alloys has no effect on hardness and ultimate tensile strength, but decreases elongation. The tarnish and corrosion resistance of Ag-Cu-Zn alloys in 1 % NaCl solution at 298 K significantly increases with increasing Zn/Cu ratio. Addition of silicon also improves tarnish resistance.
Experimental Investigation of the Corrosion Mechanism of Cemented Soils in Magnesium Sulfate Solution

Published: September 2014

Abstract
Soils stabilized by cement are found to be influenced by the environmental condition such as acid rain, seawater invasion, or industrial pollution. These adverse effects will lead to the deterioration of a structure. In order to study the process of corrosion effects including the changes of the corrosion rate of the surface, compression strength of the cemented soils and the Mg2+ and SO4
2− ion concentrations of the corrosive solutions have been determined. A series of experiments were conducted on the cemented soil blocks cured with different concentrations of MgSO4 solution. Specifically, the experimental work includes photo documentation, compressive strength tests and measurements of Mg2+ and SO4
2− ion concentrations. The test results show that the rate of corrosion for the sample surface increases with increasing concentration of the corrosive solution, while, the compressive strength decreases accordingly. Moreover, the corrosion rate degree intensifies with corrosion time. Chemical analysis of the corrosive environment indicates that CaSO4 reacts with the cemented soil, resulting in crystallizing corrosion products of 3 CaO ×Al2O3×3 CaSO4×32 H2O and CaCO3×CaSO4× CaSiO3×15 H2O. Mg(OH)2 reacts with 3 CaO ×2 SiO2×3 H2O (C-S-H) and forms new dissolving corrosive reactants such as MgO ×SiO2×H2O (M-S-H). It is concluded that the corrosion of cemented soils in MgSO4 solution is a complex reaction involving the resolving and crystallizing corrosive processes. Finally, a strength model for cemented soils is proposed based on the relationship between the compressive strength and the concentrations of Mg2+ and SO4
2− ions.
