Septooptic Dysplasia with an Associated Arachnoid Cyst
Authors: McLaurin-Jiang Skyler V. , Wood Julie K. , Crudo David F.
Published: November 2016

A 4-week-old male infant presented with hypothermia, hypoglycemia, and hyperbilirubinemia. His medical history was remarkable for hydrocephalus secondary to an arachnoid cyst, intermittent hypoglycemia, hypothermia, and poor feeding requiring nasogastric tube for nutrition. Physical exam revealed retrognathia, mild hypotonia, micropenis, and clinodactyly. Ophthalmologic exam demonstrated bilateral optic nerve hypoplasia (ONH). Laboratory data confirmed inadequate cortisol and growth hormone response to hypoglycemia, a low thyroxine level, and direct hyperbilirubinemia. Magnetic resonance imaging of the brain confirmed the known history of arachnoid cyst with hydrocephalus but also revealed anterior pituitary hypoplasia, absence of the posterior pituitary bright spot, a thin pituitary stalk, and bilateral optic nerve hypoplasia. A diagnosis of septooptic dysplasia (SOD) was made. Hormone replacement with hydrocortisone and levothyroxine was started with improvement in the infant’s glycemic control, thermoregulation, feeding, and cholestasis. This case reinforces the importance of careful physical examination and laboratory review in a patient with known history of arachnoid cyst which has been previously described as an associated feature of optic nerve hypoplasia and hypopituitarism.

Published: November 2016

Background. The prognostic significance of the neutrophil-to-lymphocyte ratio (NLR) in nonmetastatic renal cell carcinoma (non-mRCC) is controversial, although NLR has been established as a prognostic factor in several cancers. The objective of our study was to assess the prognostic significance of preoperative NLR in non-mRCC, based on a large, multicenter cohort analysis. Methods. Totally, 1,284 non-mRCC patients undergoing surgery were enrolled from six institutions between 2000 and 2014. Recurrence-free survival (RFS) and cancer-specific survival (CSS) were calculated, and the prognostic significance of NLR was evaluated. Results. Patients with higher NLR had larger tumors (p<0.001), higher T stage (p<0.001), worse Eastern Cooperative Oncology Group performance status (p<0.001), worse symptoms (p=0.003), sarcomatoid differentiation (p=0.004), and tumor necrosis (p<0.001). The 5-year RFS and CSS rates were significantly lower in patients with high NLR than in those with low NLR (each p<0.001). Multivariate analysis identified NLR to be an independent predictor of RFS and CSS (each p<0.05). Moreover, predictive accuracy of multivariate models for RFS and CSS increased by 2.2% and 4.2%, respectively, with NLR inclusion. Conclusions. Higher NLR was associated with worse clinical behavior of non-mRCC. Also, NLR was a significant prognostic factor of both RFS and CSS.

Authors: Kim Se Won , Lee Seung-Eun , Oh Young Lyun , Kim Seokhwi , Park Sun Hee , Kim Jae Hyeon
Published: November 2016

Nonislet cell tumor hypoglycemia (NICTH) is a rare but serious paraneoplastic syndrome in which a tumor secretes incompletely processed precursors of insulin-like growth factor-II (IGF-II), causing hypoglycemia. Here, we report an exceptional case of NICTH caused by nonfunctioning adrenocortical carcinoma in a 39-year-old male with recurrent hypoglycemia. The patient’s serum IGF-II/IGF-I ratio had increased to 27.8. The serum level of the IGF-II/IGF-I ratio was normalized after removal of the tumor, and the hypoglycemic attacks no longer occurred after the operation.
Split General Strong Nonlinear Quasi-Variational Inequality Problem
Authors: Zhao Yali , Han Dongxue
Published: November 2016

We introduce a split general strong nonlinear quasi-variational inequality problem which is a natural extension of a split general quasi-variational inequality problem, split variational inequality problem, and quasi-variational and variational inequality problems in Hilbert spaces. Using the projection method, we propose an iterative algorithm for the split general strongly nonlinear quasi-variational inequality problem and discuss the convergence criteria of the iterative algorithm. The results presented here generalized, unify, and improve many previously known results for quasi-variational and variational inequality problems.
Completeness of Ordered Fields and a Trio of Classical Series Tests
Authors: Kantrowitz Robert , Neumann Michael M.
Published: November 2016

This article explores the fate of the infinite series tests of Dirichlet, Dedekind, and Abel in the context of an arbitrary ordered field. It is shown that each of these three tests characterizes the Dedekind completeness of an Archimedean ordered field; specifically, none of the three is valid in any proper subfield of R. The argument hinges on a contractive-type property for sequences in Archimedean ordered fields that are bounded and strictly increasing. For an arbitrary ordered field, it turns out that each of the tests of Dirichlet and Dedekind is equivalent to the sequential completeness of the field.
A Novel Method for Optimal Solution of Fuzzy Chance Constraint Single-Period Inventory Model
Authors: Sahoo Anuradha , Dash J. K.
Published: November 2016

A method is proposed for solving single-period inventory fuzzy probabilistic model (SPIFPM) with fuzzy demand and fuzzy storage space under a chance constraint. Our objective is to maximize the total profit for both overstock and understock situations, where the demandD~jfor each productjin the objective function is considered as a fuzzy random variable (FRV) and with the available storage space areaW~, which is also a FRV under normal distribution and exponential distribution. Initially we used the weighted sum method to consider both overstock and understock situations. Then the fuzziness of the model is removed by ranking function method and the randomness of the model is removed by chance constrained programming problem, which is a deterministic nonlinear programming problem (NLPP) model. Finally this NLPP is solved by using LINGO software. To validate and to demonstrate the results of the proposed model, numerical examples are given.
Sapovirus Gastroenteritis in Young Children Presenting as Distal Small Bowel Obstruction: A Report of 2 Cases and Literature Review
Authors: Model Lynn , Burnweit Cathy Anne
Published: November 2016

Abdominal pain and distention in children are commonly encountered problems in the pediatric emergency room. The majority of complaints are found to be due to benign entities such as gastroenteritis and constipation. What confounds these diagnoses is that young children often deliver a challenging and unreliable exam. Thus, it often becomes exceedingly problematic to differentiate these benign conditions from surgical conditions requiring prompt attention including small or large bowel obstruction, volvulus, and appendicitis. The cases highlight Sapovirus as a cause of severe abdominal distention and vomiting in children and this report is the first to describe and demonstrate the impressive radiologic findings that may be associated with this infection. Surgeons should heed this information and hesitate to emergently operate on similar children.

Published: November 2016

Nanocomposites TiO2-CdS with different relative contents of CdS (molar ratios Cd/Ti = 0.02, 0.03, 0.05, 0.1, 0.2, and 0.5) were studied. The structural, photophysical, and chemical properties were investigated using XRD, Raman spectroscopy, XPS, GSDR, and LIL. XRD and Raman results confirmed the presence of TiO2 and CdS with intensities dependent on the ratio Cd/Ti. The presence of CdSO4 was detected by XPS at the surface of all TiO2-CdS composites. The relative amount of sulphate was dependent on the CdS loading. Luminescence time-resolved spectra clearly proved the existence of an excitation transfer process from CdS to TiO2 through the luminescence emission from TiO2 after excitation of CdS at λexc=410 nm, where no direct excitation of TiO2 occurs. Photodegradation of a series of aromatic carboxylic acids—benzoic, salicylic, 4-bromobenzoic, 3-phenylpropionic, and veratric acids—showed a great enhancement in the photocatalytic efficiency of the TiO2-CdS composites, which is due, mainly, to the effect of the charge carriers’ increased lifetime. In addition, it was shown that the oxidation of CdS to CdSO4 did not result in the deactivation of the photocatalytic properties and even contributed to enhance the degradation efficiency.

Published: November 2016

Radial vibration of the circular plate is presented using wave propagation approach and classical method containing Bessel solution and Hankel solution for calculating the natural frequency theoretically. In cylindrical coordinate system, in order to obtain natural frequency, propagation and reflection matrices are deduced at the boundaries of free-free, fixed-fixed, and fixed-free using wave propagation approach. Furthermore, radial phononic crystal is constructed by connecting two materials periodically for the analysis of band phenomenon. Also, Finite Element Simulation (FEM) is adopted to verify the theoretical results. Finally, the radial and piezoelectric effects on the band are also discussed.

Authors: Kulkarni Sanjeev H. , Anil Tumkur Ramakrishnarao , Gowdar Rajakumar Dyamenally
Published: November 2016

With maturity of advanced technologies and urgent requirement for maintaining a healthy environment with reasonable price, India is moving towards a trend of generating electricity from renewable resources. Wind energy production, with its relatively safer and positive environmental characteristics, has evolved from a marginal activity into a multibillion dollar industry today. Wind energy power plants, also known as wind farms, comprise multiple wind turbines. Though there are several wind-mill clusters producing energy in different geographical locations across the world, evaluating their performance is a complex task and is an important focus for stakeholders. In this work an attempt is made to estimate the performance of wind clusters employing a multicriteria approach. Multiple factors that affect wind farm operations are analyzed by taking experts opinions, and a performance ranking of the wind farms is generated. The weights of the selection criteria are determined by pairwise comparison matrices of the Analytic Hierarchy Process (AHP). The proposed methodology evaluates wind farm performance based on technical, economic, environmental, and sociological indicators. Both qualitative and quantitative parameters were considered. Empirical data were collected through questionnaire from the selected wind farms of Belagavi district in the Indian State of Karnataka. This proposed methodology is a useful tool for cluster analysis.

Authors: Saki Jasem , Foroutan-Rad Masoud , Asadpouri Reza
Published: November 2016

Background. Rodents could act as reservoir forCryptosporidiumspp. speciallyC. parvum, a zoonotic agent responsible for human infections. Since there is no information aboutCryptosporidiuminfection in rodents of Ahvaz city, southwest of Iran, hence, this survey was performed to determine the prevalence and molecular characterization ofCryptosporidiumspp. in this region.Materials and Methods. One hundred rodents were trapped from different regions of Ahvaz city. Intestine contents and fecal specimens of rodents were studied using both microscopy examination to identify oocyst and nested-polymerase chain reaction (PCR) technique for 18s rRNA gene detection. Eventually restriction fragment length polymorphism (RFLP) method usingSspIandVspIrestriction enzymes was carried out to genotype the species and then obtained results were sequenced.Results. Three out of 100 samples were diagnosed as positive and overall prevalence ofCryptosporidiumspp. was 3% using both modified Ziehl-Neelsen staining under light microscope and nested-PCR (830 bp) methods. Afterwards, PCR-RFLP was performed on positive samples andC. parvumpattern was identified. Finally PCR-RFLP findings were sequenced and presence ofC. parvumwas confirmed again.Conclusions. Our study showed rodents could be potential reservoir forC. parvum. So an integrated program for control and combat with them should be adopted and continued.

Authors: Su Miao , Yu Tengfei , Zhang Hong , Wu Yan , Wang Xiaoqin , Li Gang
Published: November 2016

This study demonstrated that glycyrrhizate (GAS) could protect HEPG2 cells against damage and apoptosis induced by H2O2 (1600 μM, 4 h). Cell viability assay revealed that GAS was noncytotoxity at concentration 125 µg/mL, and GAS (5 μg/mL, 25 μg/mL, and 125 μg/mL) protected HepG2 cells against H2O2‐induced cytotoxicity. H2O2 induced the HepG2 cells apoptosis, obvious morphologic changes were observed after Hochest 33258 staining, and more apoptotic cells were counted in flow cytometry assay compared to that of the natural group. Pretreatment GAS (5 μg/mL, 25 μg/mL, and 125 μg/mL) prior to H2O2 reverses the morphologic changes and reduced the apoptotic cells in HepG2 cells. GAS reduced the release of MDA, increased the activities of superoxide dismutase, and diminished the release of ALT and AST during oxidative stress in HepG2 cells. After Elisa kit detecting, GAS inhibited the caspase activity induced by H2O2, GAS decreased the level of caspase‐3 and caspase‐9 from mitochondria in dose‐dependent manner. Western blot results showed that pretreatment GAS upregulated the expression of Bcl‐2 and decreased the expression of Bax. These results reveal that GAS has the cytoprotection in HepG2 cells during ROS exposure by inhibiting the caspase activity in the mitochondria and influencing apoptogenic factors of the expression of Bax and Bcl‐2.

Authors: Shi Peng , Li Bin , Huo Jindong , Wen Lei
Published: November 2016

Materials corrosion study is based on plenty of contrast experiments. Traditional corrosion experiments are time-consuming and require manual corrosion grade evaluating during the experiment. To improve the efficiency of experiment, a high-throughput experiment platform is designed and accomplished. The platform mainly consists of high-throughput corrosion reaction facility, data acquisition system, and data processing system. The corrosion reaction facility supports high-throughput materials corrosion reactions under various conditions. The data acquisition system is mainly responsible for capturing the images of samples’ surface, collecting electrochemical signals, and storing them into the computer in real time. The data processing system treats the acquired data and evaluates the degree of materials corrosion in real time by program automatically. The platform not only reduces the occupation of the equipment but also improves the efficiency of sample preparation and experiment occurrence. The experimental data shows that the platform can accomplish high-throughput corrosion contrast experiment easily and reduce the time cost obviously.

Authors: Khan Farhat Ali , Zahoor Muhammad , Islam Noor Ul , Hameed Rabia
Published: November 2016

In this study cefixime and azithromycin nanoparticles were prepared by antisolvent precipitation with syringe pump (APSP) and evaporator precipitation nanosuspension (EPN) methods. The nanoparticles were characterized by XRD, FTIR, SEM, and TGA. X-ray diffraction pattern of cefixime samples showed the amorphous form, while azithromycin samples showed crystalline form. The FTIR spectra of parental drugs and synthesized nanoparticles have no major structural changes detected. The SEM images showed that nanoparticles of both drugs have submicron sized and nanosized particles. TGA analyses showed that above 30°C the decomposition of cefixime samples starts and their weight gradually decreases up to 600°C, while, in case of azithromycin, 30°C to 250°C, very small changes occur in weight; from above 250°C decomposition of the sample took place to a greater extent. The antibacterial activities of raw drugs and prepared samples of nanoparticles were determined againstStaphylococcus aureus,Shigella,E. coli, andSalmonella typhiby agar well diffusion method. Every time the nanoparticles samples showed better results than parental drugs. The dissolution rates of raw drugs and prepared nanoparticles were also determined. The results were always better for the synthesized nanoparticles than parental drug.
Speciation in Solutions of Lithium Salts in Dimethyl Sulfoxide, Propylene Carbonate, and Dimethyl Carbonate from Raman Data: A Minireview
Authors: Gorobets M. I. , Ataev M. B. , Gafurov M. M. , Kirillov S. A.
Published: November 2016

Our recent Raman studies of cation and anion solvation and ion pairing in solutions of lithium salts in dimethyl sulfoxide, propylene carbonate, and dimethyl carbonate are briefly overviewed. Special attention is paid to differences in our and existing data and concepts. As follows from our results, cation solvation numbers in solutions are low (~2) and disagree with previous measurements. This discrepancy is shown to arise from correct accounting for dimerization, hydrogen bonding, and conformation equilibria in the solvents disregarded in early studies. Another disputable question touches upon the absence of free ions in solutions of lithium salts in carbonate solvents and the statement that the charge transfer in carbonate solutions is caused by SSIPs. Direct proofs of the nature of charge carriers in the solvents studied have been obtained by means of analyses of vibrational dynamics. It has been found that collision times for free anions are short and evidence weak interactions between anions and solvent molecules. In SSIPs, collision times are an order of magnitude longer thus signifying strong interactions between anions and cations. In CIPs, collision times become shorter than in SSIPs reflecting the transformation of the structure of concentrated solutions to that of molten salts.

In the past two decades, a significant number of innovative sensing and monitoring systems based on the machine vision-based technology have been exploited in the field of structural health monitoring (SHM). This technology has some inherent distinctive advantages such as noncontact, nondestructive, long distance, high precision, immunity to electromagnetic interference, and large-range and multiple-target monitoring. A lot of machine vision-based structural dynamic measurement and structural state inspection methods have been proposed. Real-world applications are also carried out to measure the structural physical parameters such as the displacement, strain/stress, rotation, vibration, crack, and spalling. The purpose of this review article is devoted to presenting a summary of the basic theories and practical applications of the machine vision-based technology employed in structural monitoring as well as its systematic error sources and integration with other modern sensing techniques.

Published: November 2016

Not long ago, we developed a theoretical model to describe a set of chemical reactions that can potentially occur during the process of obtaining Silicon Rich Oxide (SRO) films, an off stoichiometry material, notwithstanding the technique used to grow such films. In order to elucidate the physical chemistry properties of such material, we suggested the chemical reactions that occur during the process of growing of SRO films in particular for the case of the Low Pressure Chemical Vapor Deposition (LPCVD) technique in the aforementioned model. The present paper represents a step further with respect to the previous (published) work, since it is dedicated to the calculation by Density Functional Theory (DFT) of the optical and electronic properties of the as-grown and annealed SRO structures theoretically predicted on the basis of the previous work. In this work, we suggest and evaluate either some types of molecules or resulting nanostructures and we predict theoretically, by applying the DFT, the contribution that they may have to the phenomenon of luminescence (PL), which is experimentally measured in SRO films. We evaluated the optical and electronic properties of both the as-grown and the annealed structures.
The Investigation of Nonavailability of Passive Safety Systems Effects on Small Break LOCA Sequence in AP1000 Using RELAP5 MOD 4.0
Authors: Hussain Anwar , Nawaz Amjad
Published: November 2016

The passive safety systems of AP1000 are designed to operate automatically at desired set-points. However, the unavailability or failure to operate of any of the passive safety systems will change the accident sequence and may affect reactor safety. The analysis in this study is based on some hypothetical scenarios, in which the passive safety system failure is considered during the loss of coolant accidents. Four different cases are assumed, that is, with all passive systems, without actuation of one of the accumulators, without actuation of ADS stages 1–3, and without actuation of ADS stage 4. The actuation of all safety systems at their actuation set-points provides adequate core cooling by injecting sufficient water inventory into reactor core. The LOCA with actuation of one of the accumulators cause early actuation of ADS and IRWST. In case of LOCA without ADS stages 1–3, the primary system depressurization is relatively slow and mixture level above core active region drops much earlier than IRWST actuation. The accident without ADS stage 4 actuation results in slow depressurization and mixture level above core active region drops earlier than IRWST injection. Moreover, the comparison of cladding surface temperature is performed in all cases considered in this work.

Published: November 2016

Veronicastrum axillare is a traditional medical plant in China which is widely used in folk medicine due to its versatile biological activities, especially for its anti-inflammatory effects. However, the detailed mechanism underlying this action is not clear. Here, we studied the protective effects of V. axillare against acute lung injury (ALI), and we further explored the pharmacological mechanisms of this action. We found that pretreatment with V. axillare suppressed the release of proinflammatory cytokines in the serum of ALI mice. Histological analysis of lung tissue demonstrated that V. axillare inhibited LPS-induced lung injury, improved lung morphology, and reduced the activation of nuclear factor-κB (NF-κB) in the lungs. Furthermore, the anti-inflammatory actions of V. axillare were investigated in vitro. We observed that V. axillare suppressed the mRNA expression of interleukin-1β (IL-1β), IL-6, monocyte chemotactic protein-1 (MCP-1), cyclooxygenase-2 (COX-2), and tumor necrosis factor-α (TNF-α) in RAW264.7 cells challenged with LPS. Furthermore, pretreatment of V. axillare in vitro reduced the phosphorylation of p65 and IκB-α which is activated by LPS. In conclusion, our data firstly demonstrated that the anti-inflammatory effects of V. axillare against ALI were achieved through downregulation of the NF-κB signaling pathway, thereby reducing the production of inflammatory mediators.

Published: November 2016

The widely used herbicide atrazine (ATR) can cause many adverse effects including immunotoxicity, but the underlying mechanisms are not fully understood. The current study investigated the role of oxidative stress and calcium homeostasis in ATR‐induced immunotoxicity in mice. ATR at doses of 0, 100, 200, or 400 mg/kg body weight was administered to Balb/c mice daily for 21 days by oral gavage. The studies performed 24 hr after the final exposure showed that ATR could induce the generation of reactive oxygen species in the spleen of the mice, increase the level of advanced oxidation protein product (AOPP) in the host serum, and cause the depletion of reduced glutathione in the serum, each in a dose‐related manner. In addition, DNA damage was observed in isolated splenocytes as evidenced by increase in DNA comet tail formation. ATR exposure also caused increases in intracellular Ca2+ within splenocytes. Moreover, ATR treatment led to increased expression of genes for some antioxidant enzymes, such as HO-1 and Gpx1, as well as increased expression of NF‐κB and Ref‐1 proteins in the spleen. In conclusion, it appears that oxidative stress and disruptions in calcium homeostasis might play an important role in the induction of immunotoxicity in mice by ATR.
Cardiovascular Malformations in CHARGE Syndrome with DiGeorge Phenotype: Two Case Reports
Authors: Yasuda Kazushi , Morihana Eiji , Fusazaki Naoki , Ishikawa Shiro
Published: November 2016

Both CHARGE syndrome and DiGeorge anomaly are frequently accompanied by cardiovascular malformations. Some specific cardiovascular malformations such as interrupted aortic arch type B and truncus arteriosus are frequently associated with 22q11.2 deletion syndrome, while conotruncal defects and atrioventricular septal defects are overrepresented in patients with CHARGE syndrome. CHD7 gene mutation is identified in approximately two-thirds of patients with CHARGE syndrome, and chromosomal microdeletion at 22q11.2 is found in more than 95% of patients with 22q11.2 deletion syndrome. CHARGE syndrome is occasionally accompanied by DiGeorge phenotype. We report two patients with dysmorphic features of both CHARGE syndrome and 22q11.2 deletion syndrome. Although both of the two cases did not have 22q11.2 deletion, they had typical dysmorphic features of 22q11.2 deletion syndrome including cardiovascular malformations such as interrupted aortic arch type B. They also had characteristic features of CHARGE syndrome including ear malformation, genital hypoplasia, limb malformation, and endocrinological disorders. CHD7 gene mutation was confirmed in one of the two cases. When a patient with cardiovascular malformations frequently associated with 22q11.2 deletion syndrome does not have 22q11.2 deletion, we suggest that associated malformations characteristic of CHARGE syndrome should be searched for.

Authors: Zhang Gang , Wang Chuan gang , Li Guo quan , Lin Jin zhao
Published: November 2016

A novel chaotic communication system, named Orthogonality-based Reference Modulated-Differential Chaos Shift Keying (ORM-DCSK), is proposed to enhance the performance of RM-DCSK. By designing an orthogonal chaotic generator (OCG), the intrasignal interference components in RM-DCSK are eliminated. Also, the signal frame format is expanded so the average bit energy is reduced. As a result, the proposed system has less interference in decision variables. Furthermore, to investigate the bit error rate (BER) performance over Rayleigh fading channels, the MISO-ORM-DCSK is studied. The BER expressions of the new system are derived and analyzed over AWGN channel and multipath Rayleigh fading channel. All simulation results not only show that the proposed system can obtain significant improvement but also verify the analysis in theory.
5HT3 Antagonists versus Dexamethasone in the Prevention of PONV in Patients Undergoing Laparoscopic Cholecystectomy: A Meta-Analysis of RCTs
Authors: Zhou Chengmao , Zhu Yu , Liu Zhen , Ruan Lin
Published: November 2016

Background. 5HT3 antagonist, an antiemetic alternative to dexamethasone, is an effective drug for the prevention of postoperative nausea and vomiting (PONV).Methods. PubMed and The Cochrane Library (from inception to June 2016) were searched for relevant RCTs (randomized controlled trials).Results. Seven trials, totaling 682 patients, were included in this meta-analysis. This meta-analysis demonstrated that 5HT3 antagonist was as effective as dexamethasone in preventing PONV (RR, 1.12; 95% CI, [0.86, 1.45];P=0.40) within 24 hours of laparoscopic cholecystectomy, and no significant heterogeneity was observed among the studies (I2=0%;P=0.98). During the early postoperative period (0–6 h), 5HT3 antagonists were superior to dexamethasone in reducing POV (RR, 0.31; 95% CI, [0.11, 0.93];P=0.04), while, in other postoperative stages (6–12 h, 12–24 h, and 0–24 h), it was not more effective in the prevention of POV than dexamethasone. And no significant difference was found in the prevention of PON between 5HT3 antagonists and dexamethasone at different postoperative periods (0–6 h, 6–12 h, 12–24 h, and 0–24 h).Conclusions.As a result, it is advisable to encourage 5HT3 antagonists as an alternative to dexamethasone for the prevention of PONV in patients undergoing laparoscopic cholecystectomy.

Authors: Yong-feng Yang , Yan-lin Wang , Hu Chen , Min-juan Wu
Published: November 2016

The rigid-flexible coupling system with a hub and concentrated mass is studied in this paper. Considering the second-order coupling of axial displacement which is caused by transverse deformation of the beam, the dynamic equations of the system are established using the second Lagrange equation and the assumed mode method. The simulation results show that the concentrated mass mainly suppresses the vibration and exhibits damping characteristics. When the nondimensional mass position parameterβ>0.67, the first natural frequency is reduced as the concentrated mass increases. Whenβ<0.67, the first natural frequency is increased as the concentrated mass increases. We also find the maximum first natural frequency nondimensional position for the concentrated mass.

Published: November 2016

The tumor lysis syndrome (TLS) is a collection of metabolic abnormalities that occur in consequence of the release of intracellular contents following lysis of tumor cells. TLS occurs spontaneously or after chemotherapy. Spontaneous TLS is uncommon occurrence in multiple myeloma (MM). We define a case of a 70-year-old woman patient who was found to have MM with spontaneous TLS, following a compression fracture of the T-12 vertebrae. While serum uric acid and phosphorous levels were high, low calcium levels were identified. There were also acute kidney injury and metabolic acidosis. Upon the diagnosis of TLS, she was treated with hydration, allopurinol, sodium bicarbonate, and calcium gluconate. The improvement of her laboratory data was observed. We submitted this case in order to draw attention to the presentation of MM with spontaneous TLS.
A Rough VIKOR-Based QFD for Prioritizing Design Attributes of Product-Related Service
Authors: Li Xiuzhen , Song Wenyan
Published: November 2016

Many manufacturers today are striving to offer high value-added product-related services (PRS) due to increasing competition and environmental pressure. PRS can reduce the negative impact on the environment, because it extends the life of products and minimizes the cost. Product and service planning has been considered as the critical factor to the success of PRS. Quality function deployment (QFD) has been recognized as an efficient planning tool which can convert customer needs (CNs) into design attributes of PRS involving product attributes (PAs) and service attributes (SAs). However, the subjective and vague information in the design of PRS with QFD may lead to inaccurate priority of PAs and SAs. To solve this problem, a novel rough VIKOR- (VIseKriterijumska Optimizaciji I Kompromisno Resenje-) based QFD is proposed. The proposed approach integrates the strength of rough number (RN) in manipulating vague concepts with less a priori information and the merit of VIKOR in structuring framework of compromise decision-making. Finally, an application in compressor-based service design is presented to illustrate the potential of the proposed method.
Radiation Crosslinking of Polyurethanes: Characterization by FTIR, TGA, SEM, XRD, and Raman Spectroscopy
Authors: Ghobashy Mohamed Mohamady , Abdeen Zizi I.
Published: November 2016

Gamma radiation can be used for enhancing the physical properties of polyurethane (PU). Radiation was used to crosslink a polyurethane at room temperature; four samples of the PU solid film are irradiated at variable four radiation doses 0, 50, 100, and 150 kGy under vacuum conditions. Crosslinking radiation is more common than oxidative degradation and crosslinking is believed to be more efficient in the soft segment of PU. The structure of the PUs is performed by Fourier transform infrared (FTIR-ATR), Thermogravimetric Analysis (TGA-DTG), and X-ray Diffraction (XRD) which have been used to investigate the effect of gamma radiation on the polyurethane (PU). The results showed that the radiation crosslinking of polyurethanes improved the thermal stability and the crystallinity. The microstructure modifications of polyurethane samples have also been studied as a function of the dose using the scanning electron microscope (SEM). The effects of gamma irradiation on the color changes of polyurethane were observed. The irradiated PUs have conjugated structure and are capable of emitting purple fluorescence.
Bench-Scale Flushing Experiments for Remediation of Hg-Contaminated Groundwater
Authors: Jeen Sung-Wook
Published: November 2016

Bench-scale laboratory column experiments were conducted to determine the desorption characteristics of Hg in the aquifer material from an area of known elevated Hg concentrations in groundwater under flushing conditions. The experimental results showed that columns packed with perched aquifer material (PA) showed flushing of Hg, with the general decline of effluent Hg concentrations over time (from 0.05–0.1 mg/L in the beginning to 0.0001–0.003 mg/L at the end of the experiment). Columns with lower aquifer material (LA) showed nondetectable level of effluent Hg throughout the experiment. Possibility of redissolution/desorption of Hg after static condition (for the duration of 18 days) was tested, showing only slight rebound of Hg concentrations after equilibration. The results suggest that removal of up to 20% of Hg inventory in the sediment could be achievable for the duration of the experiments (about 10 pore volumes). The results also indicate that the treated water from the water treatment plant was more effective compared to deionized water, probably due to complexing agents contained in the treated water.
Syriac Christological Dialogues and the Transmission of Theodotus of Ancyra’s Contra Nestorium
Authors: Frenkel Luise Marion
Published: November 2016

This article analyses the context of the Syriac translation of a refutation of Nestorian excerpts attributed to Theodotus of Ancyra and preserved (with lacunae) in Ms. British Library Add. 17,148, and compares the work with the transmission and translation of the texts attributed to him. The article examines the reception of Cyrillian dialogues as a form of anti-Nestorian invective in Greek, Syriac and Arabic literary communities, and discusses the possibly concomitant composition of soghyatha such as that ‘of Cyril and Nestorius’ in Syriac intellectual cultures.
Eusebius’ Historia Ecclesiastica in Syriac and Latin: A First Comparison
Authors: Noce Carla
Published: November 2016

The contemporary fifth-century Latin and Syriac translations of Eusebius’ Historia Ecclesiastica provide a great opportunity for a close comparison which both highlights the different linguistic and cultural patterns underlying the translations produced by Rufinus and the Syriac translator and also reveals many similarities between them. This article is not concerned with using the translations to reconstruct the original Greek text, but with trying to understand, by the analysis of some selected parallel passages, the theological, ideological and cultural characteristics of the Latin and Syriac contexts into which Eusebius’ Historia Ecclesiastica was translated.

The ‘foremost ornithological mystery of Costa Rica’: Amazilia alfaroana Underwood, 1896
Authors: KIRWAN GUY M. , COLLAR NIGEL J.
Published: November 2016

The hummingbird Amazilia alfaroana is known from a single specimen, collected on the Volcán de Miravalles, in north-west Costa Rica, in September 1895. Since the early 20th century, the taxon has been almost always been treated as a subspecies of Indigo-capped Hummingbird A. cyanifrons, which is otherwise endemic to Colombia, although it has also been tentatively suggested that the holotype might represent a hybrid between two unnamed species of trochilids. Our detailed analysis of the specimen reveals species-level differences between A. alfaroana and A. cyanifrons, and no evidence of characters that might suggest a hybrid between two species known to occur in the relevant region. Until molecular techniques have been brought to bear, we believe that A. alfaroana is best treated as a possibly now extinct species.
A new subterranean Iberian Cephennium with unusually modified metatrochanters (Coleoptera, Staphylinidae, Scydmaeninae)
Authors: JAŁOSZYŃSKI PAWEŁ , STRUYVE TIM
Published: November 2016

Cephennium (Geodytes) gladiator sp. n. is described from north-western Spain (Galicia). This is the first known species of Cephennium (and Cephenniini) with males showing monstrously modified metatrochanters in the form of blade-like projections as long as 3/4 of femora. Similar modifications in Scydmaeninae were known previously only among Oriental and South Pacific Glandulariini. Morphological structures of the new species and its placement in the subgenus Geodytes are discussed.

Published: November 2016

Three new species of the earthworm genus Zapatadrilus are described from Tamaulipas, Mexico: Zapatadrilus aurelius sp. nov., Zapatadrilus huastecus sp. nov., and Zapatadrilus montezumensis sp. nov. Delimitation of the new species was supported by morphological and molecular (genetic distances) evidence. Diagnostic characters of the three new species include: tubulo-racemose prostates in segments 18 and 20, penial setae absent, typhlosole present and intestine beginning in 17/18. Z. montezumensis sp. nov. is separated by its metandric condition, Z. aurelius sp. nov. by the last hearts in 13 and Z. huastecus sp. nov. by the shape of the spermathecae and patterns of genital markings.
A new deepwater legskate, Sinobatis kotlyari n. sp. (Rajiformes, Anacanthobatidae) from the southeastern Indian Ocean on Broken Ridge
Authors: STEHMANN MATTHIAS F. W. , WEIGMANN SIMON
Published: November 2016

Sinobatis kotlyari n. sp. is described, based on the nearly adult 331 mm TL holotype male from 1400 m depth in the southeastern Indian Ocean at Broken Ridge. The new species is assigned to Sinobatis due to mainly characters of its clasper and cranium fontanelle distinguishing it from congeners and other anacanthobatid skates with clasper features known. It further differs from its morphologically closest congener, S. borneensis, which is only known from the northwestern Pacific Ocean, e.g. in larger maturing size, longer snout and head, the absence of a snout filament and skin fold on tail, a longer caudal fin, and in colouration. The two congeners known from the eastern Indian Ocean, S. bulbicauda and S. cae-rulea, mature at much larger size, grow to larger maximum size and differ in numerous morphometric and meristic           characters, as well as in colouration. The type locality appears to be very remote as compared with other Indian Ocean legskates, which have primarily been found on continental and insular slopes.
High-temperature constitutive model for three-dimensional needled C/C-SiC composite under tensile loading
Authors: Xie Junbo , Fang Guodong , Chen Zhen , Liang Jun
Published: November 2016

Tensile experiments of three-dimensional needled C/C-SiC composite from room temperature to 1800℃ were performed to investigate tensile behavior. The damage characteristics and macroscopic mechanical behavior of the composite are relevant to the testing temperature and off-axis angles of the tensile loading. The tensile strength increased while the modulus decreased with the increase of temperature. A high-temperature nonlinear constitutive model was established to analyze the nonlinear stress–strain relationship of the composite. Plastic strain accumulation and stiffness degeneration were described by the plasticity and damage theories. The effect of temperature on the tensile behavior of the composite was particularly considered in this model by introducing a thermal damage variable. The proposed constitutive model can predict the stress–strain behavior of the material subjected to different off-axis tensile load, and at different temperatures. Fairly good agreement was achieved between the predicted and experimental results.

Published: November 2016

This paper provides overall comparisons of the static results of an Air Force Research Laboratory exploration into the state of the art of existing technology in composite progressive damage analysis. In this study, blind and re-calibration bench-marking exercises were performed using nine different composite progressive damage analysis codes on unnotched and notched (open-hole) composite coupons under both static and fatigue loading. This paper summarizes the results of the static portion of this program. Comparisons are made herein of specimen stiffness and strength predictions against each other and the test data. Overall percent error data is presented, as well as a list of observations and lessons learned during this year-long effort.
Attenuation of dilatational wave in ferromagnetic shape memory alloy polyurethane polymer composites

Published: November 2016

The ferromagnetic shape memory alloy polyurethane, Ni-Mn-Ga-PU, polymer composites absorb more mechanical energy than the conventional materials used for vibration damping applications. The vibration damping has been investigated using the custom-made experimental setup. The computed resonance peak values are in agreement with the experimental data. The dilatational wave decreases at high frequencies which is consistent with the theory of resonance frequency. The previously free end of the system increases the amplitude stress for an appreciable static load but loss appears to be very small. The 20% ferromagnetic shape memory alloy in polyurethane absorbs much more energy than the pure polyurethane due to the movement of twin boundaries present in Ni-Mn-Ga. The Ni-Mn-Ga-PU polymer composites of this nature can be a suitable candidate for acoustic attenuation applications.
Knowing About Racial Stereotypes Versus Believing Them
Authors: Nasir Na’ilah Suad , McKinney de Royston Maxine , O’Connor Kathleen , Wischnia Sarah
Published: November 2016

Despite post-racial rhetoric, stereotypes remain salient for American youth. We surveyed 150 elementary and middle schoolers in Northern California and conducted case studies of 12 students. Findings showed that (a) students hold school-related stereotypes that get stronger in middle school, (b) African American and Latino students experience greater divergence between stereotype awareness about their group and endorsement than other students, and (c) students who eschewed the applicability of stereotypes to them demonstrated higher engagement and achievement in math. This study has implications for studying race in schools and mathematics, and the need for urban educators to facilitate racialized counter-narratives.
