Determination of Shape Transition Concentrations in Self-Assembled Surfactant Micelles by UV-Visible Spectrophotometry
Authors: Chen Ke , Cao Guobao , Huang Zhaoxi , Zhao Fenghui , Liu Min , Chen Yong 
Published: July 2015

AbstractIn this study, the first and second critical micelle concentration (FCMC and SCMC) were determined by recording the absorbance at various surfactant concentrations using a dye probe and ultra violet (UV)-visible spectrophotometer. This method could predict the concentrations of hexagonally packed rods and palisade layer structure of ionic surfactants. The UV-visible absorbance graphs were plotted at specific concentrations. Sodium dodecyl benzene sulfonate (SDBS) and sodium dodecyl sulfate (SDS) were used as the model surfactants, and methylene blue was used as the dye probe. The FCMC and SCMC were obtained from the concentration vs. absorbance graphs. The results are in good agreement with those obtained from the fluorescence, scattering, conductivity, and surface tension measurements.
A Study of Relationship Between Oil-Water Interfacial Dilational Rheology and Oil Recovery of Alkaline Flooding
Authors: Wang Yang , Ge Jijiang , Zheng Yufei , Jiang Ping , Zhang Guicai 
Published: July 2015

AbstractIn order to find out the influence of dilational rheology on chemical flooding systems, the dilational rheology of Zhuangxi crude oil/NaOH solutions interface was investigated by DSA100 interfacial dilatational rheometer (KRÜSS, Germany). The results show that the alkaline system, which can enhance oil recovery, mainly depends on its interfacial dilational rheology, rather than interfacial tension. The greater the interfacial dilational elasticity, the higher the oil recovery is. The greater the interfacial dilational viscosity, the lower the oil recovery is. The conclusion is consistent with the change of displacement pressure in the macro displacement experiment and the change of sweep efficiency in the microscopic displacement experiment.
Surface and Fluorescence Studies of Bis-Sulfosuccinate Anionic Gemini Surfactants Derived from Dodecanol Using Different Flexible Methylene Chains as Spacers
Authors: Singh Vinayika , Tyagi Rashmi 
Published: July 2015

AbstractAn effort has been made to synthesize, characterize and evaluate the fluorescence and surface active properties of dodecanol based bis-sulfosuccinate anionic gemini surfactants using α,ω-dibromo alkanes (BSGSLA1,4; BSGSLA1,6 and BSGSLA1,8). The chemical structures of the synthesized surfactants were confirmed by spectroscopic analytical techniques viz. elementary analysis, fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance spectroscopy (NMR). Numerous surface active properties viz. surface tension at CMC (ΥCMC), critical micelle concentration (CMC), efficiency of adsorption of surfactant (pC20), surface pressure at the CMC (πCMC), adsorption amount of surfactant (Γmax) and minimum area per molecule (Amin) were determined for synthesized surfactants. Low CMC value, larger pC20 consequently higher surface activity, higher Γmax value and lower Amin values for the surfactants with higher flexible spacer length [(CH2)8] were observed. The experimental data indicated that a gemini surfactant with a larger hydrophobic flexible spacer [(CH2)8] was more readily able to form micelles which leads to a lower CMC value, larger aggregation number, and a more closely packed micelle structure. The results also indicated that a greater aggregation number and a higher micropolarity can be achieved when concentration of gemini surfactants was increased.

Authors: Vizoso M. Teresa , Quesada Carmen 
Published: July 2015

A catalogue of types from the Herbarium of the University of Granada has not previously been compiled. As a result, a search of these collections in order to compile digital images for preservation and publication yielded a large number of formerly unrecognized types.
This dataset contains the specimen records from the catalogue of the nomenclature types of fungi and lichens in the Herbarium of the University of Granada, Spain. These herbarium specimens are included in the GDA and GDAC collections, acronyms from Index Herbariorum (Thiers 2014). At this time, the type collection of fungi and lichens contains 88 type specimens of 49 nominal taxa, most from Agaricales and the genus Cortinarius, described from the western Mediterranean, mainly Spain, by the following authors: V.Antonin, J.Ballarà, A.Bidaud, G.F.Bills, M.Bon, C.Cano, M.Casares, G.Chevassut, M.Contu, F.Esteve-Raventós, R.Galán, L.Guzmán-Dávalos, R.Henry, E.Horak, R.Mahiques, G.Malençon, P.Moënne-Loccoz, G.Moreno, A.Ortega, F.Palazón, V.N.Suárez.-Santiago, A.Vêzda, J.Vila, and M.Villareal.
For each specimen, the locality indication, species name, observation date, collector, type status, related information, associated sequences, other catalogue numbers related to each type, and image URL are recorded. The dataset is associated with an image collection named “Colección de imágenes de los tipos nomenclaturales de hongos, líquenes, musgos y algas incluidos en el Herbario de la Universidad de Granada (GDA y GDAC)” (Vizoso and Quesada 2013) which is housed and accessible at the Global Biodiversity Information Facility in Spain (GBIF.ES) Hosting and Publishing Service “Biodiversity Image Portal of Spanish collections” and is also available at the Herbarium of University of Granada institutional web (Vizoso 2014a, Vizoso 2014b). That image collection contains 113 images, of which 56 correspond to the nomenclature types of 49 taxa (47 fungi, 2 lichens), the rest of the images in this collection correspond to documents and specimens or microscopy photographs which are included in the herbarium specimens of fungi. These complement and document the process of the typification.

Does Growth Attract FDI?
Authors: Iamsiraroj Sasi , Doucouliagos Hristos 
Published: July 2015

AbstractFDI is seen widely as a vital source of investment, technology transfer, and growth. The factors that attract FDI have been a longstanding source of debate. The authors present a comprehensive assessment of the accumulated evidence on one factor, the success of economic growth in attracting FDI. Meta-regression analysis is applied to 946 estimates from 140 empirical studies. The results confirm that, on average, economic growth is an important determinant of FDI. Overall, there is a positive correlation between growth and FDI and this is much larger among single country case studies than with cross-country analysis.
Lessons Learnt from Metal-On-Metal Hip Arthroplasties will Lead to Safer Innovation for all Medical Devices

Published: July 2015

Metal-on-metal bearings were re-popularised in the late 1990s with the introduction of modern hip resurfacing. Large diameter (LD) metal-on-metal (MoM) hips became more prevalent and have been the least successful group of hip implants ever used. They were rapidly adopted from 2004 until the British Hip Society stopped their use in 2012. Well functioning MoM hip results (including the BHR and Metasul) are hidden in the mire of poor results from the group of all MoM bearings. We have reviewed what happened and we make 3 observations. Firstly, collaboration between surgeons and then between surgeons and other disciplines, first identified and then solved the clinical management problems. Secondly, the problems with MoM hips occurred because hip simulation was inadequate at predicting performance in patients. They gave no indications of the biological effects of wear in the human environment. Lastly, retrieval of failed implants was essential to understanding why failure occurred. These lessons must never be forgotten and must form the basis by which new or altered implants are introduced and how they should be monitored. This will enable safer innovation for patients, surgeons and manufacturers. The problems with MoM hips will not have been in vain.

Published: July 2015

Intradermal wound closure is controversial in primary total hip arthroplasty. Randomised, controlled trials in wound closure following a total hip arthroplasty (THA) are scarce. Our hypothesis was that skin staples closure would be related to a similar complication rate and operative time as intradermal closure with polypropylene. From September 2011 to May 2012, 231 THAs in 219 patients with an average age of 62 years old (range: 21-91) were performed. No differences were observed in both groups according to sex, age, BMI and comorbidities (p = 0,82). Cases were divided into 3 groups according to medical factors that influence wound healing: group 1 (no medical history, 70.5%), group 2 (diabetes, tobacco smokers, obesity, corticosteroids, rheumatoid disease, 25%) and group 3 (organ transplantation, neoplastic patients or 2 or factors of group 2, 4.5%). Once randomised using a computer-generated method, all patients remained within the group to which they were allocated to wound closure with skin staples (Leukosan® SkinStapler PTW-35, BSN, Germany) that were used in 112 THAs in 105 patients (48%), or continuous 3.0 intradermal non-absorbable polypropylene suture (Prolene™ 0, Ethicon Inc. Somerville, New Jersey, USA) in 119 THA's in 115 patients (52%). A 3.8% wound complication rate was observed in this series, with a 2.1% complication rate for the group that was closed with skin staples and a 1.7% rate for the group with intradermal suture (p = 0.7). All the complications were treated conservatively except for one acute deep infection (0.4%) that was successfully treated with debridement, component retention and intravenous antibiotics. There were no differences in both groups related to operative time or wound length. In these series of primary elective THAs, skin staples were associated with a similar complication rate to an intradermal closure technique.

Background Ductal carcinoma in situ (DCIS) is a heterogeneous disease that has not been investigated as widely as invasive breast cancer. Thus, the search for biomarkers capable of identifying DCIS lesions that may recur or progress to invasive cancer is ongoing. Although conventional steroid hormone receptors, cell proliferation and other important tumor markers have been extensively studied in invasive tumors, little is known about the role played by androgen receptors (ARs), widely expressed in breast cancer, in DCIS. Methods We performed a retrospective study in a series of 43 DCIS patients treated with quadrantectomy only and followed up for a period ranging from 5 to 13 years, to evaluate the prognostic relevance of conventional biomarkers (estrogen receptor [ER], progesterone receptor [PgR], Ki67, human epidermal growth factor receptor 2 [HER2]) and AR. Results Our findings showed that AR and ER were not independent prognostic variables and that an AR/ER ratio cutoff of 1.13 showed a sensitivity of 75% and a specificity of 94% in predicting in situ relapse or progression to the invasive phenotype. Moreover, while the variables considered singly showed area under the curve (AUC) values ranging from 0.52% to 0.77%, the AR/ER ratio reached a very high AUC (0.92%). Conclusions These preliminary results highlight the potentially important role of AR and ER and, in particular, of their ratio, as prognostic indicators of DCIS evolution.

Introduction Secondary lymphoblastic leukemia has been rarely reported in patients with multiple myeloma. Case Reports We report 3 cases of secondary lymphoblastic leukemia in multiple myeloma patients. They shared a similar phenotype of myeloma cells and secondary lymphoblasts. The chemotherapy treatments in the 3 patients were complex due to various factors. Conclusions Multiple immune defects caused by exposure to a variety of agents can play an important role in the development of secondary lymphoblastic leukemia. Microscopic morphology and flow cytometry are important means to detect secondary malignancies in multiple myeloma. Further clinical, experimental and genetic studies of secondary malignancies in multiple myeloma will be necessary in the future.

Aims To investigate clinicopathologic characteristics, therapeutic methods, and prognostic factors in women with synchronous primary endometrial and ovarian cancers (SEOCs). Methods A retrospective review of 2 cancer registry databases in Turkey was conducted to identify patients diagnosed with SEOCs between January 1995 and December 2012. Patients with recurrent, metastatic, and metachronously occurring tumors were excluded. Multivariate logistic regression models were used to identify prognostic predictors for progression-free survival (PFS) and overall survival (OS). Results The analysis included 63 women with SEOCs. Seventy-six percent of the patients had stage I endometrial cancer, and 60% of the patients had stage I ovarian cancer. Thirty-seven patients (58.7%) had endometrioid/endometrioid histology. Optimal cytoreduction was obtained in 47 (74.6%) patients. Recurrence developed in 17 patients (27%). Multivariate analysis confirmed lymphovascular space invasion (LVSI) as an independent poor prognostic factor for OS (odds ratio [OR] 3.1, p = 0.045), whereas early-stage disease and optimal cytoreduction were found to be independent good prognostic factors for both PFS (OR 12.85, p<0.001 and OR 4.58, p = 0.004, respectively) and OS (OR 7.31, p = 0.002 and OR 2.95, p = 0.028, respectively). The 3- and 5-year OS rates were 74% and 69%, respectively. Conclusions Our study demonstrated that optimal cytoreduction, early-stage disease, and LVSI are the most significant factors affecting survival in women with SEOC.

Aim To assess patient perception toward oral chemotherapy for solid tumors, the Italian Association of Medical Oncology performed a large multi-institutional national survey. Methods A 17-item anonymous questionnaire including 7 general and 10 investigational questions with free-text, single-choice, or multiple-choice answers was administered. Analysis of response distribution according to predefined factors was described by summary measures and conducted by χ2 test and other nonparametric tests. Results From January to June 2010, 581 patients completed the questionnaire; data of 404 patients constituted the final study sample. Three groups could be distinguished according to treatment: IV chemotherapy (IV group, n = 313), oral chemotherapy (oral group, n = 48), or combined therapy (combined group, n = 43). Thirty-one (72%) patients in the combined group and 187 (60%) in the IV group expressed preference for oral therapy (p = 0.028). Limitations in family and work commitment were more frequently perceived by patients on IV than oral chemotherapy (147 (47%) vs 14 (29%) patients, p<0.05, and 134 (43%) vs 11 (23%) patients, p<0.05). A total of 134 (43%) patients on IV chemotherapy versus 15 (31%) patients in the oral group did not point out any limitation for number of tablets per day (p = 0.004). Conclusions We observed a propensity from the patient perspective in favor of oral chemotherapy that was considered to have a lower impact on family and work commitments than IV chemotherapy. The treatment that patients were taking when the questionnaire was administered likely influenced their perception and related results.

Purpose Recent epidemiological data have confirmed the increasing problem of antimicrobial resistance not only for hospitalized, healthcare-associated patients, but also for outpatients. In particular, the progressive increase in resistance to broad-spectrum antibiotics, such as third-generation cephalosporins, fluoroquinolones or carbapenems in Enterobacteriaceae, is an alarming situation for all urologists and general practitioners. Here, we aimed to review the epidemiological data of multidrug-resistant bacteria in the urological setting, in order to summarize all diagnostic and therapeutic recommendations to use in everyday clinical practice. Methods We collected all recent publications from Medline and Cochrane Library from January 2000 to December 2013. Moreover, data from the abstracts presented at the EAU and AUA Congresses during the last 5 years have also been analyzed. All papers were evaluated by an expert panel on urological infections on behalf of the Italian Urological Association (SIU). Results Fluoroquinolone and other antibiotic-resistant bacteria prevalence is normally very high in the lower urinary tract infection patients. In particular, multidrug-resistant bacteria prevalence in urological practice contributes to infectious morbidity increasing the financial costs to healthcare system. The expert panel on urological infections on behalf of the Italian Urological Association formulated new diagnostic pathway and therapeutic protocol in patients affected by urological tract infections due to multidrug-resistant bacteria. Conclusions The recent emergence of multidrug-resistant pathogens is an alarming public health issue also in urological practice with socioeconomic importance. Our practice should be revised on the basis of these new acquisitions.
Publication Productivity in the Supply Chain Management Discipline: 2011–13

Published: July 2015

AbstractThis article continues an established series of analyses across 48 years of institutional research productivity in supply chain management (SCM) journals, ranking the top 25 schools producing SCM research in 2011–13, in comparison to previous editions of the study. The current results illustrate that a core set of SCM academic institutions consistently retain strong research productivity, ranking in the top 10 across decades. However, there is significant variability in the remaining top 25 in comparison to previous editions, which is corroborated by an analysis of the concentration (i.e., diversity) of authors in the discipline that indicates that a greater number of authors and institutions continue to contribute SCM publications. However, this diversity is concentrated primarily among North American institutions as international institutions are not increasing publication productivity in the established journal set. Ultimately, the combined results provide a benchmark of the current status of the SCM discipline and present insights into its continued maturation.
Coping Strategies for Overcoming Constrained Supply Chain Technology: An Exploratory Study

Published: July 2015

AbstractConditions experienced in developing countries are characterized by high levels of uncertainty and differ considerably from those encountered in developed countries. Specifically, operational environments in developing countries constrain the supply chain technology (SCT) used by firms to manage supply chain operations. Hence, it is reasonable to conjecture that firm's operating in these types of environments might rely on and use SCT and the information they provide to manage their supply chain operations differently from firms in less constraining environments. To explore this phenomenon we conducted a grounded theory study collecting interview data from 46 logistics and supply chain managers at 16 firms across India, one of the largest and most dynamic of the developing countries. Our analysis of the data establishes that SCT constraints arise from external, internal, and relationship conditions. Emerging from the data we observed managerial emphasis on a phenomenon whereby management utilizes coping strategies to relax constraints that adversely affect their use of SCT. While our findings also revealed human intervention as a negative externality arising from the use of coping strategies, we found that management were aware of this externality and were actively addressing it as part of their efforts to relax the constraints on SCT.
Human Activity-Understanding: A Multilayer Approach Combining Body Movements and Contextual Descriptors Analysis
Authors: Granata Consuelo , Ibanez Aurélien , Bidaud Philippe 
Published: July 2015

A deep understanding of human activity is key to successful human-robot interaction (HRI). The translation of sensed human behavioural signals/cues and context descriptors into an encoded human activity remains a challenge because of the complex nature of human actions. In this paper, we propose a multilayer framework for the understanding of human activity to be implemented in a mobile robot. It consists of a perception layer which exploits a D-RGB-based skeleton tracking output used to simulate a physical model of virtual human dynamics in order to compensate for the inaccuracy and inconsistency of the raw data. A multi-support vector machine (MSVM) model trained with features describing the human motor coordination through temporal segments in combination with environment descriptors (object affordance) is used to recognize each sub-activity (classification layer). The interpretation of sequences of classified elementary actions is based on discrete hidden Markov models (DHMMs) (interpretation layer). The framework assessment was performed on the Cornell Activity Dataset (CAD-120) [ 1 ]. The performances of our method are comparable with those presented in [ 2 ] and clearly show the relevance of this model-based approach.
