Measurement of Electrical Properties as Effectiveness Appraisal of Microwave Absorption by Moulding and Core Sands Subject to Microwave Utilization
Authors: Nowak D. , Granat K. , Opyd B. 
Published: June 2014

Abstract
Within the research, carried-out were examinations of foundry rejects in form of waste moulding and core sands in order to determine effectiveness of the microwave utilization process. Presented are measurements of permittivity and loss tangent that determine behaviour of materials in electromagnetic field. Measurements were performed on a stand of waveguide resonance cavity that permits precise determination of the above-mentioned parameters with the perturbation method. Examination results of five waste moulding sands confirm that effectiveness of microwave utilization depends on electrical properties of the sandmixes (permittivity and loss tangent).

Published: June 2014

Abstract
For the evaluation of silica sands, which belongs to the most employed sands of foundry molding mixtures, there are a number of methods and techniques to characterize their quality. This implies good knowledge of their strengths and weaknesses. However, a small proportion of published results are dedicated to the impact of transport on transport routes in the foundry and the processes of dry reclamation on the properties of the silica sands, in particular on changes to the granulometry and the formation of undesirable dust sands shares, which significantly affect the properties of the sand mixture.
The aim of this contribution is the evaluation of inclination of the silica sand to crush (the formation of dust, change the granulometry) according to the newly developed methodology with regard to its nature of sand (genesis, the shape of the grains, the character of the surface).

Background Nepalese population includes a wide variety of ethnic groups namely, the Brahmin, Chettri, Dalit, Gurung, Newar, Puns, Magar Dalits population in Nepal are a traditionally victimised, underprivileged community who have been obliged to lag at the base of the public constitution in Nepal. Dalits Nepalese has poor income, education and other human development indicators. They are often landless and much poorer than the dominant caste population like the Brahmins, chetris, newars. The main objective of the study was to find out the commonest psychiatric disorder found in the poor Dalit Nepalese population in western development region of Nepal for which hospitalization is required. Method The study was a cross sectional study carried out between 1st October- 31st March 2010 at Psychiatric ward in Manipal Teaching hospital. The diagnosis of the disease was based on ICD-10 (Tenth revision) Classification of mental and behavioral disorders, Diagnostic Criteria for Research.. Results Among all the psychiatric diseases Schizophrenia, Schizotypal and Delusion Disorders 30.6% was the commonest disease seen in the Dalit Population followed by Mental and behavioral disorder due to Psychoactive Substance abuse 20.8%. Psychiatric diseases were more common in male patients 52.8%. 87.5% of the cases were <40 yrs of age, 72.2% of the patients were Hindus by religion followed by Christian 27.8%. 87.5% of the patients were unemployed and 84.7% of the patients were having monthly income <10000/month. 45.8% of the patients were students followed by housewife 34.7%. Mental and behavioural disorder due to Psychoactive Substance abuse F10-19 was found more prevalent in males [OR 8.320,95%(CI(1.717, 40.311)] as compared to female patients among the Dalit patients Conclusion Among the low socio-economic class Dalits Schizophrenia was the commonest psychiatric disorder followed by Mental and behavioral disorder due to Psychoactive Substance abuse. Psychiatric illnesses are mediated by poverty, unemployment and dearth of family income which leads to psychiatric illness among dalit Nepalese population. Interventions should target these factors to minimise the load of various psychiatric illness among poor Dalit Nepalese population.

Abstract
Nowadays there is a widespread phenomenon of dairy residue, which causes a great deal of waste. To solve this problem, the copolymer of fluorinated acrylate resin was synthesized and the resisting fluid film was prepared. The proprieties of the fluorinated acrylate resin coatings were characterized by scanning electron microscope (SEM), measuring the contact angle of the droplet liquid on the surface of the coating, the influence of acidic environment, the adhesion to substrate material, and analyzing thermogravimetry (TG) and Gas Chromatography (GC). It was found that the fluorinated acrylate resin film is a kind of resisting fluid film with excellent property and it is safe, nontoxic and readily biodegradable. So it was said a very potential dairy packaging material.
A Study on the Mechanical Property and 3D Fiber Distribution in Injection Molded Glass Fiber Reinforced PA66

Published: June 2014

Abstract
Polyamide66 (PA66) is being widely used for automobile part and other applications. In many cases, PA66 is reinforced with glass fiber to enhance its mechanical properties. In this study, the mechanical properties and glass fiber distributions in injection molded part have been investigated for glass fiber reinforced PA66. Two shapes of glass fibers, circular and flat, were used for the glass fiber reinforced PA66. X-ray microtomography (micro-CT) was used to observe the glass fiber distributions in the PA66 composites. Micro-CT photos were taken in three directions to observe the three-dimensional glass fiber distributions in the injection molded specimens. Investigation of the mechanical properties in relation to the glass fiber orientation revealed that the orientation of the fibers enhanced the mechanical properties. Glass fibers with smaller diameters resulted in better mechanical properties. Circular glass fiber reinforced PA66 exhibited better mechanical properties than flat glass fiber reinforced PA66. The skin layer showed that the glass fibers strongly orientated to the flow direction while glass fibers in the core layer orientated perpendicular to the flow direction because of fountain flows. Glass fibers in the core layer also oriented to the width direction of the flow. Consequently, glass fibers in this core region oriented three dimensionally. Full three-dimensional model of glass fiber orientation was proposed in this paper.
Feeding an Extruder of a Modified Feed Zone Design with Poly(vinyl chloride) Pellets of Variable Geometric Properties
Authors: Sikora J. W. 
Published: June 2014

Abstract
The extrusion process is greatly affected by both feed zone geometry and dimensions of pellets fed into the hopper. The paper presents the results of studies undertaken to investigate the effect of both the dimensions of a feed pocket made in the barrel below the feed opening and pellet length on the single-screw extrusion process for plasticized poly(vinyl chloride). The dependencies of the extrudate temperature, extruder screw torque, polymer mass flow rate and unit energy consumption supplied to the extruder on the above mentioned variable factors were determined. It has been found that the most advantageous solution for the investigated screw speed range is to run the extrusion process at the highest screw speeds possible, feed the extruder with pellets whose length is similar to their diameter, and use the feed pocket in the barrel.

Published: June 2014

Abstract
A study of reinforcement mechanism of multi-walled carbon nanotubes (MWCNT) in nitrile rubber (NBR) matrix was carried out. Attempts to enhance the dispersion degree of MWCNT and the NBR-MWCNT interaction were conducted using numerous approaches, namely, sonication and chemical treatments of MWCNT with nitric acid (HNO3), nitric-sulfuric acid mixture (HNO3/H2SO4) and potassium permanganate (KMnO4). Rheological behavior, dynamic properties and electrical properties of MWCNT/NBR vulcanizates were monitored. Results gained reveal the magnitude of Payne effect increases with MWCNT content and mixing time. The expanded MWCNT and continuous-network formation are observed with an increase in mixing time, yielding enhanced mechanical properties and electrical properties. With MWCNT modification, a significant reduction in the state-of-mix of MWCNT composites is exhibited. SEM results demonstrate the highest magnitude of MWCNT dispersion in the system with HNO3, but relatively poor interaction with NBR. The HNO3/H2SO4 or KMnO4 system demonstrates poor MWCNT dispersion after treatment which is probably due to the compaction of MWCNT during the drying stage after the chemical treatment process, giving the detrimental effect to mechanical and electrical properties of vulcanizates.
Mold Filling Simulation Dependence on Material Data Input for Injection Molding Process of Natural Rubber Compound
Authors: Khang T. H. , Ariff Z. M. 
Published: June 2014

Abstract
The influence of material data input towards the mold filling behavior of a natural rubber compound during an injection molding process was investigated. A commercial injection molding software (Cadmould) was utilized in evaluating the effect of using experimentally obtained material data on the mold filling progression in comparison to the actual injection molding procedure. The experimental rheological data were measured using a capillary rheometer and subsequently, the Carreau and Cross models were used to acquire the rheological parameters by curve fitting and extrapolation procedures. The cure kinetics data were obtained by employing a cure rheometer technique along with utilization of empirical approach through application of mathematical models proposed by Claxton–Liska and Deng–Isayev. It was discovered that the acquired data were able to function as reliable material data input as they were comparable with related data available in the software materials' database. Verification of the simulated filling profiles by experimental short shots specimens showed that the software Rubber Package was able to predict the realistic filling behavior of the formulated natural rubber compound inside the mold cavity when the measured material data were utilized. Whereas, the usage of available material data from the software database failed to model the mold filling progression of the prepared natural rubber compound.
Optimum Design of Balancing Systems with Real Springs
Authors: Ciupitu Liviu 
Published: June 2014

The static balancing of the weight forces of any mechanical system which is not working in horizontal plane is considered in order to decrease the acting power. From practical point of view two main ways of balancing could be taken into consideration: by mass redistribution of components and/or by adding counterweights, and by elastic forces of the springs or of the gases.The first solution is not always possible due to the clearance diagram of mechanical systems and due to increasing of the dynamic stresses of components. Second solution is more and more used to various mechanical systems and many constructive solutions were proposed in last time. The complexity of balancing systems with springs comes from the need of using zero-free length springs.In any case the mathematical model has not a unique solution. Present paper is continuing a former paper of author and is presenting a method to find the optimum solution of the simplest elastic system which is using a real spring. Design variables are the position of spring’s joints, as well as the constructional parameters of a real spring.
Optimal use of corticosteroids in nephrology
Authors: Sprangers Ben 
Published: June 2014

Abstract
The usage of corticosteroids is widespread in nephrology both in the treatment of patients with native kidney diseases and of patients who have received a kidney transplant. In glomerular diseases, steroids are part of most immunosuppressive regimens applied nowadays, and only few steroid-free immunosuppressive regimens have been reported on. It is my hope that - with the introduction of more targeted therapies - corticosteroid dosage can be reduced or eliminated completely in the future. Although corticosteroids have been the mainstay in the immunosuppressive treatment of patients who received a kidney transplant, there has been a long-standing interest in steroid avoidance and withdrawal (SAW). However, there is an ongoing debate whether SAW can be considered to be the standard of care in kidney transplantation at this moment.
Long-term survivors in advanced non-small cell lung cancer treated sequentially with cytostatic drugs and erlotinib: A retrospective study
Authors: Grigorescu Alexandru Calin 
Published: June 2014

Abstract
Objectives: This retrospective study analyzed long-term survivor patients with advanced nonsmall cell lung cancer (NSCLC) stage IIIB and IV with the aim to find the common characteristics of this group of patients. Materials and Methods: Clinical records of 76 long-term survivor patients with advanced NSCLC who took over three series of chemotherapy and had Erlotinib in one therapeutic lines. The main criterion for selection for this study was survival over 2 years. We sought to establish some features of long-term survivors, survival according to the number of lines of chemotherapy, survival by administration of Erlotinib. The Student t-test was used for calculation of P value when the data allowed this calculation and Kaplan Mayer curve was used for survival calculation. Discussions and conclusions: Relatively small number of patients cannot afford to obtain results with a high confidence interval and very heterogeneous patient characteristics were not in the favor of the creation a prototype of long-term survivors. We have found that the trend of longer survival of our patients with advanced NSCLC may be due to using multiple lines of chemotherapy and Erlotinib in the treatment strategy for these patients. Some of our conclusions are similar to other retrospective study.

SummaryAcute pulmonary embolism (PE) is a serious complication in association with malignant diseases. We describe the successful treatment of PE applying a systemic thrombolytic therapy in a 4-year-old boy with acute lymphoblastic leukaemia.The thrombolytic therapy with recombinant tissue plasminogen activator (rtPA) 0.1 mg/ kg bodyweight per hour for six hours was continued for six days without important side effects. In particular no bleeding complications were observed. Computed tomography with contrast revealed a remarkable regression of the central PE. Without further delays the chemotherapy was resumed.
Laboratory Compliance With the American Society of Clinical Oncology/College of American Pathologists Human Epidermal Growth Factor Receptor 2 Testing Guidelines: A 3-Year Comparison of Validation Procedures
Authors: Dyhdalo Kathryn S. , Fitzgibbons Patrick L. , Goldsmith Jeffery D. , Souers Rhona J. , Nakhleh Raouf E. 
Published: June 2014

Context.—The American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) published guidelines in 2007 regarding testing accuracy, interpretation, and reporting of results for HER2 studies. A 2008 survey identified areas needing improved compliance.Objective.—To reassess laboratory response to those guidelines following a full accreditation cycle for an updated snapshot of laboratory practices regarding ASCO/CAP guidelines.Design.—In 2011, a survey was distributed with the HER2 immunohistochemistry (IHC) proficiency testing program identical to the 2008 survey.Results.—Of the 1150 surveys sent, 977 (85.0%) were returned, comparable to the original survey response in 2008 (757 of 907; 83.5%). New participants submitted 124 of 977 (12.7%) surveys. The median laboratory accession rate was 14 788 cases with 211 HER2 tests performed annually. Testing was validated with fluorescence in situ hybridization in 49.1% (443 of 902) of the laboratories; 26.3% (224 of 853) of the laboratories used another IHC assay. The median number of cases to validate fluorescence in situ hybridization (n = 40) and IHC (n = 27) was similar to those in 2008. Ninety-five percent concordance with fluorescence in situ hybridization was achieved by 76.5% (254 of 332) of laboratories for IHC− findings and 70.4% (233 of 331) for IHC+ cases. Ninety-five percent concordance with another IHC assay was achieved by 71.1% (118 of 168) of the laboratories for negative findings and 69.6% (112 of 161) of the laboratories for positive cases. The proportion of laboratories interpreting HER2 IHC using ASCO/CAP guidelines (86.6% [798 of 921] in 2011; 83.8% [605 of 722] in 2008) remains similar.Conclusions.—Although fixation time improvements have been made, assay validation deficiencies still exist. The results of this survey were shared within the CAP, including the Laboratory Accreditation Program and the ASCO/CAP panel revising the HER2 guidelines published in October 2013. The Laboratory Accreditation Program checklist was changed to strengthen HER2 validation practices.
Le manifeste en danse
Authors: Sintès Guillaume 
Published: June 2014

Force est de constater que la pratique du manifeste en danse ne s’inscrit pas dans une tradition discursive importante, que ce soit en termes de production ou d’analyse critique. À vrai dire, les exemples qui ont marqué, durablement (ou pas), le champ chorégraphique français se comptent sur les doigts d’une main.
Il conviendra d’analyser l’évolution d’une pratique qui, si elle reprend les codes identitaires du genre, fonctionne à rebours des autres disciplines artistiques : délaissant une démarche singulière, menée au sein d’un groupe, au profit d’un mouvement collectif prônant la revendication d’une politique culturelle chorégraphique large, et oscillant entre acte de légitimation d’un art (et non d’une esthétique) et volonté d’institutionnalisation et de structuration du champ.
