Lessons Learned

Chemotherapy for recurrent, metastatic squamous cell carcinoma of the head and neck need not be known for extreme toxicity. The weekly regimen studied here has been demonstrated to be tolerable and effective.

Background

The objective of this study was to establish the response rate, progression-free survival (PFS) and overall survival (OS), and safety profile of weekly docetaxel, platinum, and cetuximab (TPC) in patients with relapsed or metastatic squamous cell carcinoma of the head and neck (SCCHN).

Materials and Methods

Twenty-nine patients with metastatic or recurrent SCCHN with an Eastern Cooperative Oncology Group (ECOG) performance status <3 were enrolled in an institutional review board-approved phase II trial. This study permitted prior chemoradiation, radiation, and/or surgery, provided that 3 months had elapsed since the end of the potentially curative treatment. Patients received cisplatin 30 mg/m2 or carboplatin area under the curve (AUC) 2, docetaxel 30 mg/m2, and cetuximab 250 mg/m2 weekly for 3 weeks, followed by a break during the fourth week, for a 28-day cycle. Planned intrapatient dose modifications were based on individual toxicity.

Results

Twenty-seven patients received TPC and were evaluable for response and toxicity. Rates of complete response (CR), partial response (PR), and confirmed PR were 3%, 52%, and 30%, respectively. The overall objective response rate was 56%. Estimated median PFS and OS were 4.8 and 14.7 months, respectively. The rates of grade 3 and 4 worst-grade adverse events (AEs) per patient were 85% and 7%, respectively. Dose density through cycle 4 was preserved for all patients; however, treatment beyond cycle 6 with the TPC regimen proved unfeasible.

Conclusion

Weekly docetaxel, cisplatin, and cetuximab is an effective regimen for patients with metastatic or recurrent SCCHN. Response rates, PFS, and OS compare favorably with other combination chemotherapy treatments. Grade 4 toxicity rates observed in this study were substantially lower than those described with regimens using less frequent, higher-dose chemotherapy schedules.
Determination of flow stress of magnesium alloy sheet AZ31B by reverse analysis method
Authors: Ma Xinwu , Fang Wang , Zang Wenjuan
Published: March 2018

The reverse analysis method is presented to determine the flow stress of magnesium alloy sheet AZ31B based on limiting dome height tests. The determination of flow stress is treated as an optimization problem by the reverse analysis technique. The unknown coefficients in the flow stress equation are regarded as design variables, and the difference between experimental loads and corresponding predictions by the finite-element method is calculated as an objective function. The response surface method is used to solve this optimization problem, and the flow stress of the material is determined by optimal values of design variables. In this study, the flow stress of an AZ31B sheet is determined at 250°C by reverse analysis. The limiting dome height tests for AZ31B sheet are carried out and sampling points are chosen from load against stroke curve. The finite-element analysis model for the sheet forming according to the test condition is set up. The numerical simulations are performed with sample values of design variables and objective functions are calculated. The response surface equation is formulated by the regression analysis and the optimal values of design variables are obtained by minimizing the equation.
Consequences of dewatering cement mortars incorporated with ground Bayburt stone
Authors: Ince Ceren , Derogar Shahram
Published: March 2018

The detrimental effects of the rapid dewatering of cement mortars due to the interaction of wet mortar and brick substrate at the freshly mixed state in masonry construction are often addressed in the literature. The desorptivity and hence very high water releasing ability of cement mortars result in a great water loss during dewatering that significantly affects the fresh and hardened state properties of the end product. The paper therefore investigates the possible role of ground Bayburt stone incorporation in cement mortars on dewatering characteristics and the consequences of this effect at the hardened state properties of these mortars in construction practice. The paper begins with the measurement of the parameters of water transport kinetics and individually reports the effect of dewatering on the mechanical properties and durability characteristic of cement mortars incorporated with ground Bayburt stones. The results reported in this paper strongly suggest that ground Bayburt stone incorporation in cement mortars significantly compensate the degree of dewatering, and this vital feature does not only decreases the influence of dewatering on mechanical properties but also results in an enhanced durability characteristics of cement mortars.
A CFD simulation of CLSM filling with piping on Herschel–Bulkley rheological model
Authors: Zhang Xuesong , Yu Rangang , Chen Jinping
Published: March 2018

In order to study and predict the flowing behaviour of controlled low-strength material (CLSM) slurry filling with piping transportation, a three-dimensional computational fluid dynamics simulation is carried out based on the Herschel–Bulkley (H-B) rheological model. The simulation is validated by L-pipe flow experiments of CLSM on the flow time and flow pattern. The analysis results show that it is reliable to use the H-B model to simulate the flow of the CLSM slurry. On this basis, simulations are performed to predict the dynamic characteristics of CLSM slurry filling with piping transportation and analyse the velocity distribution and pressure variation in pipeline. The simulation results are consistent with the basic law of power flow, which proves the rationality and effectiveness of the method. The study on the filling characteristics of CLSM slurry pipeline lays a theoretical foundation for the realisation of low-cost, safe and efficient filling of abandoned pipelines.

Authors: Punetha Piyush , Samanta Manojit , Mohanty Piyush
Published: March 2018

An accurate evaluation of interface friction between two geosynthetics under dynamic loading conditions is vital for the seismic design of landfills, flood protection systems and so on. This paper presents the results of an experimental investigation conducted on different geosynthetic–geosynthetic interfaces involving geomembrane and geotextile under static and dynamic loading conditions, using direct shear and shake table tests. The effect of normal stress, sliding velocity, frequency and the number of cycles on the dynamic coefficient of friction for the geosynthetic–geosynthetic interfaces has been investigated using a fixed-block set-up on a shake table. The results show that the dynamic coefficient of friction for geomembrane–geomembrane interfaces decreases with an increase in normal stress, sliding velocity and frequency. The dynamic coefficient of friction for geotextile–geotextile interfaces decreases with an increase in normal stress and frequency, while it increases with an increase in sliding velocity. However, the number of cycles has a negligible effect on the shear behaviour of all the interfaces tested.

Abstract             It
is approved that artificial neural networks are considerably effective in
analyzing flows in which traditional methods and statics are inadequate to
solve. In this article, we use a two-layer feedforward network with tan-sigmoid
transmission function in input and output layers with PISA of Turkey and
Organisation for Economic Cooperation and Development (OECD) science level
values. OECD Programme for International Student Assessment (PISA) surveys
reading, mathematical and scientific literacy levels every three years. The
PISA assessment works on young people’s ability to apply their knowledge and
skills to real-life problems and situations rather than on how much
curriculum-based knowledge they have. Assessments are made on three core fields
reading literacy, mathematical literacy and scientific literacy. The conclusion
is that PISA is an important global benchmarking tool, but that bureaucrats and
the media need to use the rich data that have been collected  together 
with  information  about  
their  academic performance.
According to statistical evaluations, regression value of ANN was higher than
value of regression methods.Keywords: PISA, Artificial Neural Networks, Regression

Published: March 2018

In this study, a new composite material containing polyacrylamide (PAA) and diatomite
(D) was developed and characterized for effective removal of Methylene Blue
(MB) dye in aquatic medium. The obtained new composite material, polyacrylamide-diatomite (PAA-D) was characterized by
point zero charge (PZC), FTIR analysis. The adsorption properties of new composite
material were investigated comprehensively and experimental variables were
optimized such as concentration, pH, temperature, time and ionic strength.
Experimental data were evaluated by using theoretical adsorption models. The
maximum adsorption capacity of material was calculated as 0.019 mol kg−1
by considering Langmuir equation. The constants calculated from Freundlich and
DR model were found as 0.075 and 0.034, respectively. Adsorption kinetic was
also explained with pseudo second order and intra particular diffusion models.
Experimental studies were showed that adsorption was endothermic and occurred
spontaneously. New developed material can be used as potential adsorbent in
order to removal of methylene blue from various medium such as wastewater.

The aim of this study was to investigation of in

vitro cytotoxic and genotoxic effects of infusion and decoction aqueous

extracts obtained from Rosmarinus officinalis, Lavandula stoechas

L. and Tilia cordata Mill. on human peripheral blood lymphocytes. For this purpose, lymphocytes taken from 3

females, were treated with aqueous extracts of R. officinalis (1.5 and 3

mg/ml),  L. stoechas (0,4 and 1,2

mg/ml) and T. cordata (1 mg/ml and 3 mg/ml) for 48 hours. PBS was used

as negative control and Mitomycin C (MMC) (0,25 μg/ml) was used as positive

control in experiments. Cytotoxic effect of extracts on lymphocytes was

determined by calculating mitotic index. Also, chromosome aberrations

micronucleus formations were determined. 

All extracts considerably decreased the

cell division in lymphocytes depending on the increased concentration in

comparison with control groups (p<0,01). Also cells in metaphase decreased.

Thus, no chromosomal aberration was observed in lymphocytes. However, extract

treatments induced the formation of micronucleus in lymphocytes when compared

to control groups (p<0,01). 3 mg/ml decoction extracts of L. stoechas and

T. cordata showed the highest cytotoxic effect on lymphocytes, and the

highest genotoxic effect appeared after 48 h treatment with 1.2 mg/ml decoction

extract of L. stoechas.

Authors: Singh Ajit Kumar , Narula Gagan Kumar , Nambiar Bala Chandran , Bedi Parvinder Singh , S. Deeparani , Rajkhowa Moloy
Published: March 2018

Background: A growing body of evidence has shown Tranexamic Acid (TXA) is effective in decreasing perioperative blood loss and transfusion requirements in both primary and revision joint arthroplasty. TXA is a synthetic drug which limits blood loss through inhibition of fibrinolysis and clot degradation. It helps reduce requirement of colloids and crystalloids and hence provides better haemodynamic stability. The aim of this study was to detect the effect of tranexamic acid on coagulation parameters and effect on bleeding in knee replacement surgeries performed under tourniquet.Methods: Patients undergone surgeries of Total Knee Replacement (TKR) performed under tourniquet were included in the study. A single dosage of 20 mg/kg per body weight of tranexamic acid was administered after application of a tourniquet. Three times blood sample was collected, and coagulation parameters were recorded and compared. The first sample was collected at the time of TXA injection and application of a tourniquet, second after 4 hours and third after 24 hours post TXA injection. Coagulation parameters noted were analyzed using Statistical analysis by SPSS software. All parameters were compared in relation to baseline i.e. at the time of TXA injection.Results: On comparison of demographic profile, morbidity, sofa score and hemodynamic parameters there was the insignificant difference (P > 0.05). Repeated measures of ANOVA at 95% Confidential Interval P value was 0.000 which is less than the significant level that is 0.05 so that value of Platelet Function (PF), Activated Coagulation Time (ACT) and Clot Rate (CR) at 0 hrs, 04 hrs and 24 hrs was statistically significant. Correlation between blood loss and difference of the value of ACT at 0 hrs and 04 hrs is a small negative correlation but statistically nonsignificant (P value is 0.359).Conclusions: After TXA administration there is a change in coagulation parameters like an Activated Coagulation Time (ACT), Platelet Function (PF), and Clot Rate (CR) measured at three intervals, hence it can be a guide to detect early derangement in the coagulation profile in a patient undergoing knee replace surgery. TXA correlation between blood loss with changes in parameters of coagulation i.e. ACT, PF and CR were noted but not significant.

Application of Emerging-State Actor Theory: Analysis of Intervention & Containment Policies Using the ISIS Case
Authors: Clancy Timothy
Published: March 2018

This paper builds upon a theory of emerging-state actors using ISIS as a case study. This paper seeks to apply the theory in analyzing intervention & containment policies to use against emerging-state actors, using ISIS as the case study. Two baseline scenarios are used for evaluation – one replicating the historical foreign intervention against ISIS and a counter-factual where no foreign intervention occurred. Eleven contemporary military policies were tested against these baseline in isolation, combination, at different timing windows and under hypothetical “best case” conditions as well as operationally constrained. Insights of these tests include the influence of ethnographic envelopes, timing windows. Finally, a policy based on emerging-state actor theory is tested performing substantially better across primary measures than other policies or the historical baseline. This is compared against a falsified-policy designed to disprove that emerging-state actor theory contributed to the benefits. This paper’s contributions are a practical application of system dynamics simulations and systems-thinking to current problems, generate insights into the dynamics of emerging-state actors and intervention strategies, and demonstrate utility for future application of the underlying simulation in other scenarios involving non-state actor irregular conflict including terrorism, insurgents, or emerging-state actors.

Published: March 2018

The past two decades has seen a growing demand for high-power, high-voltage utility scale inverters mostly fueled by the integration of large solar PV and wind farms. Multilevel inverters have emerged as the industry choice for these megawatt range inverters because their reduced voltage stress, capable of generating an almost sinusoidal voltage, in-built redundancy, among others. This paper present a new Switched-Source Multilevel Inverter (SS MLI) architecture. The new inverter show superior over existing topologies. It has reduced voltage stress on the semiconductor, uses less number of switches –reduced size/weight/cost and increased efficiency. The new SSMLI is comprised of two voltage sources (V1, V2) and 6 switches. It is capable of generating 5-level output voltage in symmetric modes (i.e., V1 = V2), and 7-level output voltage in asymmetric modes (i.e., V1 ≠ V2). To demonstrate the validity of the proposed inverter, simulations results using MATLAB® /Simulink® for 5- and 7-level output voltages are presented . The simulations are also verified experimentally using a laboratory prototype.
IWRM as a System Approach to Water Security: Evidence from the Awash River Basin of Ethiopia
Authors: Hailu Reta , Tolossa Degefa , Alemu Getnet
Published: March 2018

Integrated Water Resources Management (IWRM) is one of the system thinking approaches emerged in the 1990s. Since then it has been applied in various countries and contexts. However, the implementation of the IWRM is contested. There are paucity of literature and guidelines as to how the concept can be operationalized. In Ethiopia, there is no evidence that IWRM is successfully instituted. Particularly, IWRM has never been implemented in the Awash River Basin. The study generated data from household and institutional surveys, in-depth interviews, focused group discussions, workshops, and secondary sources. Multiple sources of data were triangulated and thematically summarized. We found that pragmatic water resources management through system approach helps to recognize river basin as a bigger system in which the natural and human systems function. This resolves the problem of fragmentations among among various actors, sectors, interest and priorities. That it facilitates the coordination of various subsystems. The operationalization of IWRM as a system to secure water resources require the establishment and/or strengthening of the interactions of various systems, subsystems, and the elements within the entire basin system. Finally, enabling institutional environments should be considered as a medium of realizing IWRM.
Reparación y escucha del sujeto-víctima: discursos y prácticas en la intervención psicosocial con víctimas del conflicto armado en Colombia
Authors: Castro-Sardi Ximena , Olano Juliana
Published: March 2018

En el actual escenario colombiano de posconflicto se enmarcan los procesos de reparación integral a las víctimas del conflicto armado, lo que demanda la creación de dispositivos asistenciales que posibilitan la rehabilitación psicosocial y la integración social de aquellos que han sido vulnerados en sus derechos. Objetivo: Esta investigación se propone analizar las concepciones que los agentes interventores que trabajan en los dispositivos de atención a víctimas construyen en torno a esta población, así como los discursos que orientan sus prácticas de intervención. Método: Mediante una metodología cualitativa de nueve entrevistas en profundidad se recogieron las concepciones, representaciones y prácticas de dichos agentes. Resultados: Los hallazgos muestran que la concepción dominante entre los interventores es la de la víctima como sujeto sufriente y que sus prácticas de intervención responden apenas marginalmente al tratamiento del sufrimiento de las víctimas, ya que en las prácticas descritas prevalece la dimensión jurídica y la de empleabilidad, a través de intervenciones padronizadas. Conclusiones: Finalmente se discuten y proponen algunos de los desafíos que estos equipos de trabajo enfrentan en los procesos de atención y acompañamiento a esta población vulnerable. © Universidad Católica Luis Amigó - Revista Colombiana de Ciencias Sociales.

Objetivo: analizar las condiciones en las que se desarrolla el oficio del editor de los grandes grupos en Argentina. Método: el corpus de datos cualitativos proviene de 40 entrevistas en profundidad a editores y otros agentes de editoriales de Argentina. Esta técnica se complementó con observaciones y fuentes secundarias del sector. Resultados: la financiarización del sector editorial latinoamericano introdujo la necesidad de maximizar ganancias, lo cual promovió cambios en los modos de producción y circulación y en las maneras de hacer y pensar de los editores. Estos cambios se observan en transformaciones en los planteles y en la adquisición de un horizonte comercial en la dinámica laboral. Las exigencias comerciales conviven con apuestas simbólicas que impactan en la construcción del oficio. Conclusiones: la tensión entre la lógica comercial y la cultural permite sostener que la articulación entre prácticas concretas, herramientas técnicas, trayectorias y saberes heredados les brinda a los editores una capacidad de “estar en el mundo” en un espacio no exento de contradicciones que caracteriza a la dinámica actual de producción de libros. © Universidad Católica Luis Amigó - Revista Colombiana de Ciencias Sociales.

Authors: Mompremier Rojacques , Fuentes Mariles Óscar Arturo , Becerril Bravo José Elías , Ghebremichael Kebreab
Published: March 2018

This paper presents the analysis of the variation of haloacetic acids (HAAs) for different pipe materials in a distribution system. The work involved an experimental study on a simulated distribution system assembled in the Hydraulic Laboratory of the Engineering Institute at the National Autonomous University of Mexico (Instituto de Ingeniería UNAM). Two different scenarios were investigated based on different pipe materials, variation of temperature and initial chlorine concentrations (4.0 and 4.5 mg/L). Feed water with varying amounts of organic content was dosed with varying amounts of chlorine concentration. Water samples were collected from different locations in the distribution system and analyzed for physicochemical properties and HAAs determination. The results of this research demonstrated that the concentration of HAAs in the different segments of the distribution systems varied depending on pipe material, initial chlorine concentration, pH, residence time and the presence of natural organic matter.

Authors: Almeida Laryssa Garcia de , Vianna João Batista Macedo
Published: March 2018

Introdução: O termo Acidente Vascular Cerebral é usado para designar uma doença vascular, que ocorre em uma área cerebral e resulta em déficit neurológico focal ou global. Corresponde à importante causa de morbidade e mortalidade em adultos de meia-idade e idosos. No Brasil, são registradas cerca de 100 mil mortes por Acidente Vascular Cerebral anualmente. Mesmo com a alta taxa de mortalidade, ainda existem poucos estudos epidemiológicos sobre essa doença. Objetivos: Determinar o perfil epidemiológico dos pacientes internados por Acidente Vascular Cerebral em um hospital de ensino. Métodos: Foi realizado estudo de coorte transversal, que analisou 166 prontuários de pacientes internados por Acidente Vascular Cerebral no Hospital Escola de Itajubá (MG), no período de março de 2016 a fevereiro de 2017.

Authors: Nanda Shweta , Som Bhupender K
Published: March 2018

A Medical Wearable Device provides vital sign monitoring. Therefore, it involves monitoring of one or more of the following or any other physiological vital that has application in fitness monitoring and medical diagnostic such as; blood glucose level; blood pressure; pulse rate; electrocardiograph (ECG) patterns; respiration rate; respiration effectiveness (e.g., blood oxygen saturation). Hence the Medical Wearable Devices are extremely useful precautionary gadgets. A number of such devices are available in market these days. Despite of their usefulness they are not very popular in India. This may be due to low level of awareness. As Metropolitan cities is primary market for such gadgets.

This paper focuses on the awareness level of the medical wearable devices in Delhi-NCR and studies awareness with respect to suitable demographics. Further, this paper identifies the key parameters in role of the education, qualification and purchase power parity for adoption of this device. The insights drawn from the vast health literature helps to develop the behavioral conceptual framework which becomes the basis to gather the primary data.

Authors: Sujadi Sujadi , Hasibuan Hasrul Abdi , Purba Abdul Razak , Lubis Mahmud Irvan
Published: March 2018

Twenty four Cameroon accessions have been planted in Adolina oil palm seed garden area in 2010 and have been analyzed their fatty acid, iodine value and beta carotene contents to reveal their genetic variability. Analysis of variance results for fatty acid, iodine value and beta carotene content characters show that there are significant differences for palmitat, stearat, oleat, linoleat acid, iodine value and beta carotene content. Fatty acid content, iodine value and beta carotene content showed medium to high broad sense variability which verify that there is a high genetic impact of these characters. Ten Cameroon accessions with beta carotene content more than 1.000 ppm have been identified and can be used as future breeding material for IOPRI in gaining new varieties with beta carotene content more than 1.000 ppm. In addition there is one accession showed iodine value more than 57.1 Wijs which has a potential used as crossing material in obtaining new superior varieties which have high iodine values. In outline there are negative correlation( in one side) between palmitat acid with stearat, oleat acid and iodine value in other side.
Magic state parity-checker with pre-distilled components
Authors: Campbell Earl T. , Howard Mark
Published: March 2018

Magic states are eigenstates of non-Pauli operators. One way of suppressing errors present in magic states is to perform parity measurements in their non-Pauli eigenbasis and postselect on even parity. Here we develop new protocols based on non-Pauli parity checking, where the measurements are implemented with the aid of pre-distilled multiqubit resource states. This leads to a two step process: pre-distillation of multiqubit resource states, followed by implementation of the parity check. These protocols can prepare single-qubit magic states that enable direct injection of single-qubit axial rotations without subsequent gate-synthesis and its associated overhead. We show our protocols are more efficient than all previous comparable protocols with quadratic error reduction, including the protocols of Bravyi and Haah.

On strong summability and convergence
Authors: Malkowsky Eberhard
Published: March 2018

We give a survey of the recent results concerning the fundamental topological
properties of spaces of stronly summable and convergent sequences, their ?-
and continuous duals, and the characterizations of classes of linear
operators between them. Furthermore we demonstrate how the Hausdorff measure
of noncompactness can be used in the characterization of classes of compact
operators between the spaces of strongly summable and bounded sequences.
A new Ф-generalized quasi metric space with some fixed point results and applications
Authors: Abbas Mujahid , Leyew Bahru , Khan Safeer
Published: March 2018

In this paper, the concept of a new ?-generalized quasi metric space is
introduced. A number of well-known quasi metric spaces are retrieved from
?-generalized quasi metric space. Some general fixed point theorems in a
?-generalized quasi metric spaces are proved, which generalize, modify and
unify some existing fixed point theorems in the literature. We also give
applications of our results to obtain fixed points for contraction mappings
in the domain of words and to prove the existence of periodic solutions of
delay differential equations.
A fixed point problem under a finite number of equality constraints involving a Ciric operator
Authors: Rakocevic Vladimir , Samet Bessem
Published: March 2018

Let (E,???) be a Banach space with a cone P. Let T,?i : E ? E (i = 1,2,...,r)
be a finite number of mappings. We obtain sufficient conditions for
the existence of solutions to the problem {(Tx = x, ?i(x)=0E, i=1,2,..., r,
where 0E is the zero vector of E, and T is a mapping satisfying a
Ciric-contraction. Some interesting consequences are deduced from our
main results.
From graphical metric spaces to fixed point theory in binary related distance spaces
Authors: Roldán López , Shahzad Naseer
Published: March 2018

Very recently, many fixed point results have been introduced in the setting
of graphical metric spaces. Due to their intimate links, such works also deal
with metric spaces endowed with partial orders. As the reachability
relationship in any directed graph (containing all cycles) is a reflexive
transitive relation (that is, a preorder), but it is not necessarily a
partial order, results on graphical metric spaces are independent from
statements on ordered metric spaces. The main aim of this paper is to show
that fixed point theorems in the setting of graphical metric spaces can be
directly deduced from their corresponding results on measurable spaces
endowed with a binary relation. Finally, we also describe the main advantages
of involving this last class of spaces.

Common fixed points of (α-ψ)- generalized rational multivalued contractions in dislocated quasi b-metric spaces and applications
Authors: Abbas Mujahid , Rakocevic Vladimir , Leyew Bahru
Published: March 2018

In this paper, the concept of (?-?)-generalized rational contraction
multivalued operator is introduced and then the existence of common fixed
points of such mapping in complete dislocated quasi bmetric spaces is
obtained. Some examples are presented to show that the results proved herein
are potential generalization and extension of comparable existing results in
the literature. We also study Ulam-Hyers stability of fixed point problems
of (?-?)-generalized rational contraction multivalued operator. We also
obtain some common fixed point results for single and multivalued mappings
in a complete dq b-metric space endowed with a partial order. As an
application, the existence of a continuous solution of an integral equation
under appropriate assumptions is obtained.
