Polyol Silver Nanowire Synthesis and the Outlook for a Green Process

Silver nanowires (AgNWs) have a broad range of applications including nanoelectronics, energy conversion, health care, solar cells, touch screens, sensors and biosensors, wearable electronics, and drug delivery systems. As their characteristics depend strongly on their size and morphology, it is essential to find the optimal and most cost-effective synthesis method with precise control over the size and morphology of the wires. Various methods for AgNW synthesis have been reported along with process optimization and novel techniques to increase the yield and aspect ratios of synthesized AgNWs. The most promising processes for synthesis of AgNWs are wet chemical techniques, in which the polyol process is low cost and simple and provides high yield compared to other chemical methods. Reaction mechanism is one of the most important factors in strategies to control the process. Our purpose here is to provide an overview on the main findings regarding synthesis, preparation, and characterization of AgNWs. Recent efforts in the polyol synthesis of AgNWs are summarized with respect to product morphology and size, reaction conditions, and characterization techniques. The effect of essential factors such as reagent concentration and preparation, temperature, and reaction atmosphere that control the size, morphology, and yield of synthesized AgNWs is reviewed. Moreover, a review on the novel modified polyol process and reactor design such as continuous millifluidic and flow reactors to increase the yield of synthesized AgNWs on large scales is provided. The most recent proposed growth mechanisms and kinetics behind the polyol process are addressed. Finally, comparatively few available studies in green and sustainable development of 1D silver nanostructures through the application of natural products with inherent growth termination, stabilization, and capping characteristics are reviewed to provide an avenue to natural synthesis pathways to AgNWs. Future directions in both chemical and green synthesis approaches of AgNWs are addressed.
OutSystems Compiler Optimizations

Ideally, compilers should produce target code that is as good as can be written by hand. Unfortunately, this goal cannot be achieved in the usual case, and it’s up to the optimizer to do its best job in approximating this ideal situation. Traditional optimizing compilers have advanced to the point where the do an excellent job of optimizing a single procedure. Accordingly, optimization research has begun to focus on interprocedural analysis and optimization. And for OutSystems, the lack of inter-procedural optimizations represents a weakness in supporting large-scale applications, with complex inter-procedural relationships and modularity requirements. In this paper, we present a case study of optimizations in the OutSystems Platform compiler. It is presented the theoretic background behind optimization techniques, and it is given focus on designing an inter-procedural optimizer for the current OutSystems compiler.
FAM64A Promotes Osteosarcoma Cell Growth and Metastasis and Is Mediated by miR-493

Aberrant expression of FAM64A was correlated with cell proliferation in various cancer types. We examined the expression of FAM64A and the upstream gene miR-493 in OS. The functions of miR-493 were revealed through extensive experiments. We found an increase of FAM64A gene and protein in OS tissues. Overexpression of FAM64A resulted in promoting tumor proliferation, migration, and invasion. The miR-493 targeted and negatively regulated FAM64A. Our data showed that upregulation of FAM64A in OS correlated with poor prognosis.
MODELLING OF FULLERENE PRODUCTION BY THE ELECTRIC ARC-DISCHARGE METHOD

The molecules from fullerene family are rapidly becoming a part of our daily lives due to the wide range of their unique properties and extensive field of their potential applications. High demand for these materials revealed a necessity to understand the process of fullerene growth in order to optimize their production. Since the fabrication technique has a large influence on the material proper-ties, several methods have been suggested. The focus of this seminar will be electric-arc discharge method, where fullerens are formed by vaporizing graphite electrodes in a low pressure gas atmosphere. Detailed understanding of growth mechanisms in the arc discharge reactor requires the development of a mathematical model that approximates the physical behaviour of nonequilibrium plasma coupled with nonlinear chemical systems. In this seminar several such models from various authors ([1], [2], [3]) are presented along with chemical kinetics model [Scott, 2004], that describes nucleation and growth of carbon clusters and fullerens. In addition, a complementing literature review on the subject is performed. The majority of the contents in chapters 3, 4 and subchapters 5.1, 5.2 and 7.1 have been taken from the review of Nataša Grlj [4]. These chapters have been only slightly modified and complemented.
Effects of Direct Renin Blockade on Renal & Systemic Hemodynamics and on RAAS Activity, in Weight Excess and Hypertension

Aim The combination of weight excess and hypertension significantly contributes to cardiovascular risk and progressive kidney damage. An unfavorable renal hemodynamic profile is thought to contribute to this increased risk and may be ameliorated by direct renin inhibition (DRI). The aim of this trial was to assess the effect of DRI on renal and systemic hemodynamics and on RAAS activity, in men with weight excess and hypertension. Methods A randomized, double-blind, cross-over clinical trial to determine the effect of DRI (aliskiren 300 mg/day), with angiotensin converting enzyme inhibition (ACEi; ramipril 10 mg/day) as a positive control, on renal and systemic hemodynamics, and on RAAS activity (n = 15).
Evaluation of nutrition knowledge using the komPAN questionnaire in acute coronary syndrome patients hospitalized in an invasive cardiology unit A preliminary report

Introduction. Cardiovascular diseases are the major cause of mortality in Poland. Thus, both primary and secondary prevention should include lifestyle modification, including proper nutrition. The aim of the study was to examine dietary habits and nutritional beliefs for the purpose of evaluating the nutrition knowledge of cardiac patients after an acute coronary syndrome [ACS; non-ST-segment myocardial infarction (NSTEMI) and ST-segment myocardial infarction (STE -MI)] undergoing invasive treatment. Material and methods. The study included 100 patients, including 35 women and 65 men aged 53.43 ± 10.11 years [mean ± standard deviation (SD)], admitted urgently due to ACS to the 2 nd Department of Cardiology. The study used part C of the questionnaire: “Nutrition Beliefs” that consisted of 25 statements assessing nutrition knowledge. For each correct answer (“True” or “False”), 1 point was assigned, and for an incorrect answer or “Hard to say”, 0 points were assigned. Then, the points were added up. Results. It was found that only 20.8% (N = 21) of subjects followed dietary recommendations as advised by a physician. The majority of respondents were diagnosed with an excessive body mass: obesity in 35.4% (N = 35) of subjects, and overweight in 38.4% (N = 38) of subjects. Nutritional self-assessment was reported to be at a good level in 71.3% of pa tients (N = 72). However, the actual nutrition knowledge was found to be at a good level in only 6.9% (N = 7) of subjects. Conclusion. Patient nutrition knowledge as assessed using the komPAN questionnaire was found to be mostly at a sa tisfactory level, despite high self-assessment results provided by the respondents. There is a great need for regular nutrition education.

Comparison of national strategies in France, Germany and Switzerland for DRR and cross-border crisis management

The ESPREssO project (funded by the European Union’s Horizon 2020 research and innovation programme, under Grant Agreement No. 700342) prioritises the need for overcoming barriers to disaster risk reduction (DRR) in Europe, with cross-border crisis management identified as one of its three central challenges. In this paper, we present a synthesis of the different legal, policy and scientific approaches to DRR in France, Germany and Switzerland, through work carried out for the ESPREssO project on the basis of stakeholder interviews and an analysis of legal and policy references. A comparison of these three differing DRR strategies is then carried out, focusing specifically on resulting impacts for cross-border crisis management, capitalizing on lessons learned from the tri-national border region Upper Rhine Valley to complete the analysis. © 2017 The Authors.

The diversity and richness of archaea in the northern continental slope of South China Sea

[Objective] The archaea are recognized as key players participating in the global biogeochemical cycles in marine sediments. The knowledge upon community structure and metabolic functions of archaea is the basis to understand their potential contributions on the biogeochemical cycles globally. [Methods] Archaeal diversity in the sediments of three areas at the northern continental slope of SCS was surveyed using high-through sequencing for 16S rRNA gene. [Results] The major archaeal groups in the sediments was found to include Bathyarchaeota, Thermoplasmata, Woesearchaeota (DHVEG-6), Thaumarchaeota (Marine Group I), Lokiarchaeota and Marine Hydrothermal Vent Group (MHVG), also with low abundant of AK8, Marine Benthic Group A and Terrestrial Hot Spring Crenarchaeota Group (THSCG). Anaerobic methane oxidation (AOM) microbes (Anaerobic methanotrophic archaea, ANME), mainly ANME-1, ANME-2ab and ANME-2c were also found in the potential gas hydrate zone. Methyl coenzyme-M reductase alpha subunit (mcrA) gene, which encodes the key enzyme in methane metabolism, was also recovered from these sites, implying potentially active methane cycling. Quantitative PCR results showed that the abundance for bacterial 16S rRNA gene, archaeal 16S rRNA gene and mcrA gene were 10−10 copies/g (wet weight), 10−10 copies/g (wet weight) and 10−10 copies/g (wet weight), respectively. [Conclusion] These results revealed high diversity of archaea and rich microbial recourses in SCS sediments, layed the foundation for further analysis and understanding of archaeal mediated carbon cycling in the sediments of SCS.
Formation of Au-Si eutectic on silicon surface

In September 2007 an experiment on a Si(100) sample with a Au film around 40Å thick deposited on top was carried out under Ultra High Vacuum at the European Synchrotron Radiation Facility in Grenoble. The measurements mainly involved x-ray diffraction techniques to probe the behaviour of the surface as the temperature was changed and increased above the eutectic melting point. The study of such eutectic has a very high technological importance for applications such as the growth on nanowires. The presence of a highly reproducibe crystalline layer sitting on top of a liquid surface was observed, confirming previous literature.
Statistical Time Estimates for Deepwater Completions in the Gulf of Mexico: Integration of Neural Networking and Distribution Modeling

Predicting completion time in deepwater wells is an imminent necessity in the modern well construction cycle. The primary objective of this paper is to present a novel integrated approach of statistical analysis and neural network models to identify well characteristics and their impact on total time to complete a well. Using a neural network, fifteen crucial attributes from the Dodson Database were used in this study and analyzed for relative impact with respect to time. These attributes included primary parameters such as well depth and interval number. Wells in the database were assigned a value, depending on their fifteen attributes, that correlated to length of time to complete. The program designated prospect wells a value using the same time weighted impact system, as well as the same impact parameters. Wells within the database with most similar values to the prospects were used in the statistical analysis for total completion time. Actual data were used for fifteen parameters in the program for “Dark Star,” “Liberty,” and “Terrapin” to test the reliability of the statistical analysis. Estimates for “Dark Star” and “Liberty,” which were completed in 2014, were within 5% of field completion time. “Terrapin” is yet to be completed; however, the programs estimate was within 3% of the Approval For Expenditure (AFE). With access to the data provided by Stone Energy as one of the active operators in GOM, this paper presents a valuable methodology to estimate completion time.
Virtual mass in accelerated bubbly flows

This paper addresses the important issue of virtual mass force concept in accelerated bubbly flows. Firstly, a literature review about virtual mass modeling is presented, since most references to virtual mass are focused on its effects on numerical stability calculation, but almost no mention are made to its effect on the actual flow computations. Results show that the inclusion of virtual mass in its correct form leads to great differences in differential pressure calculations and are of fundamental importance in order to agree with experimental results. Commercial package CFX4.4 was used to perform the simulations and various models for the virtual mass force were implemented, using the FORTRAN user routines, and compared among them and with the experimental data of Lewis & Davidson (1985). The influence of the virtual mass coefficient was also investigated. The theoretical value of 0.5 calculated for a sphere in an infinite medium has shown not to be adequate for high void fractions (>15%). A form of this coefficient varying with void fraction was implemented, showing better agreement with experimental data.
Chapter 6 Your Story is My Story: Examining the Research Literature on Black Women in Teacher Education

Research literature examining the experiences of faculty of color, particularly women in higher education, reveals a pattern of institutional and attitudinal barriers, which is directly linked to successful recruitment and retention of learners and faculty of color (Brayboy, B. M. (2003). The implementation of diversity in predominately White colleges and universities. Journal of Black Studies, 34(1), 72–87; Gregory, 2001; Hughes, R. L. , & Howard-Hamilton, M. F. (2003).

Bolton, MA: Anker Publishers; Turner, 2002; Watson & Shealey, 2010). This chapter provides a review of the recent and relevant research on Black women in teacher education. In addition, the authors conducted a review of research specifically addressing the experiences of Black women in teacher education during the last 10 years. Findings from this summative analysis highlight recent research on the experiences of Black women faculty and shed light on the implications for future research as well as leadership and program development.
The use of cannabinoids in Parkinson’s disease

Parkinson’s disease (PD) is a very common neurodegenerative disorder in the elderly for which there is no current cure. The neuropathological hallmark is the loss of dopaminergic cells in the substantia nigra pars compacta. Current treatments use L-DOPA and dopamine agonists to replace the lack of dopamine, however such treatments have significant limitations and side effects, thus, the need for more effective therapeutics is critical. Cannabinoids (CBs), which include ∆9-tetrahydrocannabinol, cannabidiol and ∆9-tetrahydrocannabivarin, target the endocannabinoid (ECB) system, which is highly involved in dopaminergic functions. The endocannabinoid system undergoes extensive changes in PD such as upregulation of the ECB anandamide, in addition to variations in the concentration of CB receptors. These changes can be modified and corrected using CB1 and CB2 receptor ligands and by modulating the levels of the ECB catabolic enzyme fatty acid amide hydrolase (FAAH), in order to increase endogenous anandamide (AEA) levels. Therefore, CBs may represent a valid therapeutic alternative to treat PD. CB drugs may not only treat the symptoms of the disease, but may also help slow down disease progression. Nevertheless, with regards to motor symptoms of PD such as rigidity, bradykinesia, postural instability, resting tremors and levodopa-induced dyskinesia, evidence of the therapeutic effect of CBs is somewhat inconsistent. Although only evidence in the preclinical phase, more promising results have been seen in general regarding the neuroprotective effect of CBs, as well as in relation to sleep, depression and pain.
CARCINOMA DE CÉLULAS ESCAMOSAS EN CANINOS DE CULIACÁN, SINALOA, MÉXICO: ESTUDIO RETROSPECTIVO (2006-2014) Squamous Cell Carcinoma in Dogs from Culiacan, Sinaloa, Mexico: Retrospective Review (2006-2014)

The aim of this study was to determine the frequency and risk factors associated with Squamous Cell Carcinoma (SCC) in dogs. A retrospective descriptive study was carried out at the Pathology Laboratory, Faculty of Veterinary Medicine and Animal Husbandry, Sinaloa Autonomous University. From January 2006 to December 2014, a total of 108 cytological samples obtained through Fine Needle Aspiration Biopsy and stained with Papanicolaou were selected. Fifty two additional samples from skin biopsies of dogs embedded in paraffin and stained with Hematoxilyn-Eosin, were also selected. Information concerning the following variables was collected: age, gender, anatomical location of presentation, coat color and breed. The study showed that in Culiacan the frequency of SCC in dogs with cutaneous neoplasia was 20%. It was also found that the associated risk factors were as follows: white coat, prepuce as anatomical location, male gender, Bull terriers as for breed and two to four years old. This study agrees with results from other authors, who have also found similar results as for coat color, anatomical location and breed. However, with respect to the variable age, it was noticed that dogs were younger, compared to those previously reported with SCC.
A diagnostic immunohistochemical panel for challenging cases of high-grade urothelial carcinoma versus high-grade prostatic adenocarcinoma

Background Although the differentiation between high-grade urothelial carcinoma (UC) and high-grade prostatic carcinoma (PC), especially in small biopsies, is challenging, a definite diagnosis is mandatory as the distinction between both entities has significant impact on the patient management. Aim The aim of the present study was to identify the best immunohistochemical marker(s) that can differentiate between these two entities. Materials and methods We applied an immunohistochemical panel using the newly described marker GATA3 (GATA binding protein 3), as well as p63, CK7, and CK20 as UC markers and the newly discovered marker AMACR (&agr;-methylacyl-CoA-racemase) with prostate-specific antigen (PSA) as a PC marker. This study was conducted on 38 high-grade UC cases and 34 high-grade PC cases. Results GATA3 was a highly specific UC marker with diffuse staining pattern, specificity of 100% and diagnostic accuracy of 91.6%. It was followed by p63, which showed patchy staining, specificity of 100% and diagnostic accuracy of 83.7%. CK7 showed either diffuse or patchy staining with specificity of 91.2% and diagnostic accuracy of 80.6%. CK20 showed mostly patchy staining, with a much less diagnostic accuracy of 68% than those of all other UC markers that were used. Regarding PC, PSA showed high specificity (97.4%) and high diagnostic accuracy (95.8%). AMACR showed a specificity of 73.7% for PC and diagnostic accuracy of 84.7%, but it was more sensitive compared with PSA and its results does not vary in high grades. Statistical analysis revealed that combined GATA3/AMACR panel has the best diagnostic characteristics. Conclusion We concluded that the newly discovered marker GATA3 with AMACR are the best preliminary panel to be applied in the challenging cases of high-grade UC and PC.
Assembly Line Education: A Novel Educational Technique for Today's Learners

Background Education is undergoing a transformation. The traditional passive lectures are failing to capture and inspire the new generation of learners who value more active and collaborative learning techniques. Objective We sought to create a novel educational technique to integrate into our curriculum that would be more personalized, employ more active learning and collaboration, and allow for an effective assessment of resident strengths and weaknesses. Discussion We created a monthly assembly line education academic half-day that evolved to replace one of the typical in-classroom didactics each month. Faculty run small-group simulation rooms, procedure workshops, competitive ultrasound, and wellness stations through which residents and medical students rotate. Conclusion This novel education technique resulted in a more personalized approach that increased resident interest, sparked the creation of a very popular MedEd-Simulation elective, and allowed the faculty to gain a better sense of resident strengths and deficiencies.
