The End of Intellectuals
Authors: Makhlouf Peter 
Published: May 2019

Abstract
In 1979, Edward Said attended a colloquy on Middle East politics hosted by Jean-Paul Sartre and Les Temps Modernes in the apartment of Michel Foucault. He would later go on to publish his reflections on this experience in a short piece titled “Diary.” Reading this piece alongside Said’s larger oeuvre, as well as those of his predecessors Foucault and Antonio Gramsci, this article attempts to offer a theory of intellectual responsibility that may be applied to the BDS movement today. In turn, Orientalism and The Question of Palestine, published in the same year as the colloquy, offer a salient political allegory for the relation of the United States to the question of Palestine writ large when read as a dyad as they are intended to be. In closing, the article attempts to apply the theory of intellectuals derived from Said’s work by reflecting on the potential for the particular case of BDS to speak to a set of universal concerns on the Left.
The Resistance to Boycott
Authors: Sacks Jeffrey 
Published: May 2019

AbstractThis article traces the relations between the 2017 vote of the Modern Language Association (MLA) against supporting the boycott of Israeli academic institutions and the practices of reading and literary interpretation upon which the MLA is founded. It argues that the MLA's affirmation of the exteriority of literature and literature studies to boycott advances a Bildungs-centric conception of language, literature, and self-understanding, which the MLA, through its vote, expansively promotes on a global scale—across literatures and languages. And it argues that the MLA, insofar as it advocates this bildungs-centrism, participates in a history of violence—of slavery, genocide, and settler colonialism—which remains constitutive for the formation of literary fields and objects of study. In doing so this article examines a single Hebrew-language novel, S. Yizhar's Khirbet Khizeh (1949), which dramatizes, in the colonization of Palestine, the relationships between reading, literary form, and death-imparting, genocidal violence.

Published: May 2019

Abstract
Sulfamic acid functionalized PVC-coated nano-silica (NS) catalyst (NS@PVC-EDA-SO3H) was prepared via multi-step treatment processes and characterized by FT-IR, N2 adsorption-desorption, TGA/DTG, XRD, TEM, STEM-EDS, as well as acid-base back-titration. The hydroxyalkylation of phenol with formaldehyde to bisphenol F was employed to evaluate in detail its acid catalysis performances. The results indicated that the newly constructed NS@PVC-EDA-SO3H possessed richer short mesoporous to macroporous channels and highly exposed sulfamic acids and could exhibit excellent hydroxyalkylation activity and reusability owing to fast mass transfer and reaction rates for the conversion of substrates, as well as excellent structural and chemical stabilities. This new solid acid was obviously superior to the conventional homogeneous concentrated sulfuric acid and heterogeneous sulfonated resin catalysts in catalytic activity and reusability, which could achieve a remarkable formaldehyde conversion (99.9%) and selectivity of bisphenol F (94.5%) under optimal hydroxyalkylation conditions. Furthermore, it could also be recovered easily and used repeatedly at least nine times without an obvious decrease in activity.

Published: May 2019

Abstract
A colorimetric method involving a novel gold nanoparticle-curcumin system is described for determination of melamine in urine. The natural phenol curcumin can reduce chloroauric acid to form well-dispersed gold nanoparticles, while at high concentration of melamine, reduction is suppressed and blue aggregates are quickly formed, which is confirmed by UV-vis spectroscopy and TEM images. The ratio of absorbances at 673 and 546 nm increases linearly in the 0.5 to 4 ppm melamine concentration range, and the detection limit is 0.16 ppm. The assay has been applied to analyze urine samples and showed recoveries with RSDs of &lt;5%. The gold nanoparticle-curcumin based analytical system is simple for one-pot synthesis, convenient for visual detection and rapid requiring only 30 min. Therefore, it is a promising assay approach for melamine adulteration and well suited for homecare testing.

Published: May 2019

Abstract
Nanoparticles of samarium(III) oxide (Sm2O3), gadolinium(III) oxide (Gd2O3) and iron(II,III) oxide (Fe3O4), which have different roles in biomedical applications, were synthesized and embedded in biocompatible polydopamine to make them more dispersible, compatible and non-aggregate so as to fully exploit their features in the human body. Herein, the synthesis procedures of the nanoparticles with different sizes and the embedding procedures in polydopamine were investigated in comparison with coating with silica. The particles (60–100 nm diameter) of Sm2O3 and Gd2O3 synthesized by the calcination method were coated by silica shell (80–100 nm thickness) but their dispersibility in water was less. The nanosized particles (4–7 nm) of Sm2O3 and Gd2O3 synthesized by the polyol solvent method were protected by polyol to be dispersed in water. Separately, Fe3O4 nanoparticles (17 nm) were fabricated by co-precipitation reaction. Each nanoparticle was successfully embedded into spheres of polydopamine, although the preparation of composites depended on solvent amount, metal precursor amount and reaction solution pH. The co-embedding of three particles in a polydopamine sphere was also proved by elemental analysis.
Mapping of local recurrence after pancreaticoduodenectomy for distal extrahepatic cholangiocarcinoma: implications for adjuvant radiotherapy
Authors: Jung Wonguen , Kim Kyubo , Min Seog Ki , Nam Eun Mi , Lee Jeong Kyong 
Published: May 2019

Objective:
To generate a map of local recurrences after pancreaticoduodenectomy (PD) for patients with distal extrahepatic cholangiocarcinoma (DEHC) and to evaluate the adequate target volume coverage encompassing the majority of local recurrences when the clinical target volume (CTV) for pancreatic cancer was applied.

Methods:
We retrospectively reviewed the records of DEHC patients who underwent pancreaticoduodenectomy and had postoperative CT scans acquired between 1991 and 2015 available. The sites of local recurrence were delineated on individual CT scans, and then, mapping was manually performed onto template CT images. Coverage of each site of local recurrence was evaluated by applying the CTV defined according to Radiation Therapy Oncology Group (RTOG) consensus guidelines (CTVRTOG ) for target delineation in the postoperative treatment of pancreatic head cancer.

Results:
Of the 99 patients, 36 patients had a total of 62 local relapses identifiable by postoperative CT scans; the relapses were the most frequent in the choledochojejunostomy (CJ) site, 11 sites (17.7%); para-aortic area, 10 sites (16.1%), superior mesenteric artery area, 10 sites (16.1%); and portal vein area, 9 sites (14.5%). 21 sites (33.9%) were not covered by the CTVRTOG, and the most common site of local recurrence outside the CTVRTOG was the CJ site.

Conclusion:
When mapping of local relapses was evaluated according to the CTVRTOG, the choledochojejunostomy site was identified as a high-risk area of local recurrence but was insufficiently covered within the CTVRTOG. These findings may help construct a target volume for postoperative radiotherapy in DEHC.

Advances in knowledge:
Mapping local recurrences can aid in defining appropriate target volume for postoperative radiotherapy in DEHC.
Design and Dynamic Pricing of Vertically Differentiated Inventories
Authors: Stamatopoulos Ioannis , Tzamos Christos 
Published: May 2019

We study a model in which a monopoly firm designs the quality profile of its inventory and then dynamically updates its pricing menu for a finite selling horizon to maximize revenue. In a counterfactual scenario, a social planner goes through the same process to maximize total welfare. We show that in both scenarios the problem of dynamically pricing heterogeneous-quality (vertically differentiated) inventories is equivalent to that of dynamically pricing homogeneous-quality inventories, in the sense that a solution to one implies a solution to the other. Moreover, we prove a strong scarcity result, which suggests that the sale of a product drives up the prices on all remaining products, whether of higher or lower quality. We then consider product line design under a production technology that utilizes costly and potentially limited resources. We show that with unlimited (but costly) resources, the revenue maximizer undersupplies quality to all products compared with the social planner. With limited resources, we show that the revenue maximizer exhibits elitism: he overallocates (underallocates) resources on the production of high-quality (low-quality) products. However, as the volume of expected consumer arrivals increases to infinity, both the revenue maximizer and the welfare maximizer allocate resources equally across products.

Supports' Perspectives on the Social Experiences of College Students With Intellectual Disability
Authors: Prohn Seb M. , Kelley Kelly R. , Westling David L. 
Published: May 2019

AbstractAlthough postsecondary education (PSE) programs for students with intellectual disability (ID) have grown in recent years, there is little information about the social status of these students on an inclusive college campus. Because many college students without disability play a significant and enduring role in the functioning of PSE programs for students with ID, they provide an opportunity for insight into this question. This study used 3 peer-support focus groups (n = 15) to capture the observed social experiences of PSE students living and learning in a college community. The supports identified 4 foundational elements that determined whether students were more likely to be socially included or excluded. These elements were the campus environment, support, individual skills for developing and maintaining social relationships, and social self-determination. Recommendations are included which may assist postsecondary education programs in reducing social barriers and contribute to students' social inclusion in the college environment.

Authors: Saunders Alicia F. , Root Jenny R. , Jimenez Bree A. 
Published: May 2019

Abstract
There is very limited research on inclusive mathematics instruction for students with extensive support needs (i.e., moderate to severe intellectual disability, autism, multiple disabilities) and this is a critical area of need. The purpose of this article is to propose a framework for mathematics instruction for students with extensive support needs in inclusive settings using practices that have been found effective in more restrictive settings, combined with the limited findings on effective inclusive practices for students with extensive support needs. A conceptual model for mathematics instruction for students with extensive support needs is illustrated and described. The proposed model provides guidance for collaborative teams and key stakeholders when planning for mathematics instruction in inclusive settings. Barriers to including students with extensive support needs in general education mathematics settings are discussed and recommendations for overcoming these barriers are described.
Impregnation of Fibrous Materials with Lc Polyesters and Blends on Their Base

Published: May 2019

Abstract
Impregnation and infiltration of fibrous materials by LC copolyester melts and the blends with viscous thermo-plastic polysulphone were quantitatively described as unsteady and steady stages in terms of rheological characteristics of the melts using an equivalent capillary model. Addition of LC polyester to viscous thermoplastic melt noticeably enhances impregnation condition. Study of the melt flow through various capillaries demonstrated a development of the melt slippage at high shear rate along the capillary walls. Slippage phenomena may be important at the initial stage of impregnation but can be neglected for final stage due to low shear rate in the last case. On the other hand, at those conditions a yield stress of the melt may considerably complicate the impregnation process due to a drastic viscosity increase.
Rheology of Reactive Polymer Blends: Separation of Mixing and Reatcion Steps
Authors: Muller R. , Bouquey M. , Mauguière F. , Schlatter G. , Serra C. , Terrisse J. 
Published: May 2019

Abstract
The crosslinking reaction in various types of polymer blends was followed by rheological measurements. Miscible polymers with controlled glass transition temperature, chain length and number of functional units per chain were synthesized by bulk radical copolymerization. Other experiments were carried out on immiscible systems based on commercial polymers. Blends were either prepared in a batch mixer or directly in the parallel-plate geometry of a rotational rheometer. Due to the low glass transition or melting temperature of most blend components, it was usually possible to separate the mixing step which was carried out at low temperature from the crosslinking reaction which was followed by small amplitude dynamic measurements at higher temperatures. The influence of several parameters on the reaction was studied, in particular : the reaction temperature, the amount of shear during the mixing step (or mixing time), the number of functional units per chain in each blend component and the blend composition. For the miscible blends, a master curve for the dependence of the elastic modulus G’ as a function of reaction time could be drawn for different functionalities and blend compositions.
Rheological Characterization of Bentonite Suspensions and Oil-In-Water Emulsions Loaded With Bentonite
Authors: Bekkour K. , Ern H. , Scrivener O. 
Published: May 2019

Abstract
With stress controlled rheometer we investigate the behavior for different concentrations, of paraffin oil-in-water emulsions, bentonite suspensions as well as charged bentonite emulsions. We were particularly interested in how aging affects the rheological properties. Using a structural model, we correlate the macroscopic experimental results to the fluid microstructure characteristic parameters and we calculate the emulsions and suspensions mean characteristic unit size. The comparison of these mean particle diameters with those obtained by microscopy and light-scattering measurements confirms the soundness of such procedure to estimate the structural characteristics, the effective concentrations and the effective mean particle diameter of oil-in-water emulsions and bentonite suspensions.

Authors: Kitano Takeschi , Hashmi S.A.R. , Chand Navin 
Published: May 2019

Abstract
Dynamic rheological parameters such as storage modulus, G’, loss modulus, G”, and dynamic viscosity, h’, at 200°C were studied for Kevlar fibres, glass fibres and their hybrids reinforced linear low density polyethylene (LLDPE). Parallel plate rheometer was employed for these tests. G’, G” and h’ increased with the increased reinforcement and angular frequency, w. Two sets of reinforcement, 10 and 20 vol.% of fibres are used in LLDPE. The composition of fibres in hybrid composites was varied. The replacement of glass fibres with Kevlar increases the values of G’, G” and h’. The values of these rheological parameters also increased with the thickness of the composite. This increase was associated with the decreased average orientation of fibres present in the composite. The effects of the change in strain amplitude on G’ and G” is also studied and reported here.
Numerical Studies of the Effect of Constitutive Model Parameters as Reflecting Polymer Molecular Structure on Extrudate Swell
Authors: Nithi-Uthai Nattapong , Manas-Zloczower Ica 
Published: May 2019

Abstract
PolyFlow, a software package based on the finite element method was employed to simulate the extrudate swell for polybutadiene of various molecular weight (Mw) and molecular weight distribution (MWD). We calculated the relaxation spectra for the different samples and then inserted the spectra into a standard K-BKZ constitutive model used in the numerical simulations. Accurate predictions of MWD confirm the completeness of frequency range in the oscillatory shear experimental data. In turn, the wholeness of relaxation spectra as substantiated by MWD predictions, sustain the level of confidence when using constitutive models based on these spectra. We demonstrate the importance of using the full range of relaxation spectrum rather than a short range around typical shear rates for the accuracy of the numerical predictions. We found extrudate swell ratio (ESR) to be strongly dependent on MWD and stress conditions at the die exit.

Authors: Atak Gunay Baydar , Bayraktar Emine , Mehmetoglu Ülkü 
Published: May 2019

Abstract
In this study, enantiomerically pure (S)-1-phenylethanol was produced via asymmetric bioreduction of acetophenone. Ispir bean (Phaseolus vulgaris) was used as an alcohol dehydrogenase (ADH) source since whole cells are cheaper than isolated enzymes. Acetone powder methodology was applied for biocatalyst. Glucose was used as a cosubstrate in-order to regenerate cofactor (NADPH). The reactions were carried out in an orbital shaker whose temperature and agitation rate can be controlled. (S)-1-phenylethanol concentration was analyzed by HPLC using a Chiralcel OB column. Effects of the reaction time, substrate concentration, cosubstrate concentration and biocatalyst concentration on the (S)-1-phenylethanol production were investigated using Response Surface Methodology (RSM). 36 h bioreduction time, 6 mM acetophenone concentration, 25.15 mM glucose concentration, and 175 mg/mL biocatalyst concentration were determined as optimum values. In these conditions, 2.4 mM (S)-1-phenylethanol was obtained in phosphate buffer (pH=7.0) at 30°C with >99% enantiomeric excess.

Published: May 2019

Abstract

Objective
To estimate the prevalence of overweight and obesity among a cohort of children with type 1 diabetes mellitus (T1DM) and its metabolic consequences.

Methods
This was a cross-sectional study conducted in the Pediatric Diabetic Clinic at Shaare Zedek Medical Center and Clalit Health Care Services. Background information was taken from the patients’ files. Anthropometric measures, blood pressure, waist and hip circumference (WC and HC), hemoglobin A1c (HbA1c) and lipid profile were recorded. The prevalence of metabolic derangements was compared between normal and overweight children.

Results
The study included 96 patients with type 1 diabetes, mean age 14.1 ± 3.7 years, mean diabetes duration 3.9 ± 3 and mean HbA1c level 8.1 ± 1.4% (65 mmol/mol). Thirty-seven percent of the study population were overweight and of them 11.5% were obese. In the overweight group, the high-density lipoprotein (HDL) levels were significantly lower and systolic blood pressure (SBP) and diastolic blood pressure (DBP) values were higher compared with normal weight participants. Multivariate analysis showed that BMI and age at study affected SBP and HDL levels, while age at study and HbA1c levels affected DBP. Female patients were significantly overweight compared to males and had higher low-density lipoprotein (LDL) and cholesterol levels. Waist-to-hip ratio, an indicator of central obesity, was abnormally high among overweight males and females.

Conclusions
In our cohort of children with type 1 diabetes, there were a significant number of overweight children, with a higher prevalence in females. Components of metabolic syndrome were more prevalent among overweight and obese diabetic individuals.
Effect of chemical additives on softness components of hygiene paper
Authors: Park Jung Yoon , Melani Lili , Lee Hyeonggyu , Kim Hyoung Jin 
Published: May 2019

Abstract
Chemical additives are used singly or in combination to impart functionality to hygiene paper (suggested). In particular, in the hygiene paper making process, dry strength agent, wet strength agent, softener, and other are widely used. The effects of chemical additives on the softness components were evaluated. In the case of surface softness, there was no change in MMD according to the addition of dry and wet strength agents. The MMD (mean deviation from the average friction of coefficient) was decreased by adding a softener, which is the purpose of its addition to the hygiene paper making process. The softness and wet strength were improved when the wet strength agent was added before the softener. In addition, lotion treatment was applied to the surface of tissue paper. The surface softness component of non-silicone-based lotion was similar or improved, which may overcome the problems of silicon-based lotion.
Theological Critiques of Natural Theology: A reply to Andrew Moore
Authors: Loke Andrew Ter Ern 
Published: May 2019

Summary
In leading academic publications, Oxford theologian Andrew Moore has systematically developed new objections to natural theology based on Karl Barth’s methodological arguments, historical considerations as well as theological considerations related to Scriptural passages such as Romans 1:18 ff, the noetic effects of sin, whether natural theology leads to the God who has revealed himself in Christ, the work of the Holy Spirit, and attitudes such as humility and self-denial. I demonstrate the inadequacy of his methodological and historical arguments and show that the numerous Scriptural passages cited by Moore do not really support his objections, and that Moore neglects other passages (e. g. Acts 14:15–17, 17:22–31) which contradict his arguments. I defend the value of natural theology as the first of a two-step approach which (1) shows that there is a Creator God (2) shows that this God has revealed himself in Christ.
