It is theorized that enhanced thermal heating may result from exposing single-walled carbon nanotubes （SWNts） embedded in a conductive host to radiofrequency （RF） electric fields. We examine the RF-induced （13.56 MHz） heating behaviors of 95% metallic- and semiconducting-enriched SWNts （m-/s-SWNts） suspended in aqueous solutions with varying NaC1 molarity （0.001 mM-1 M）. the heating effects were only evident for host molarities below 1 mM （equivalent to 0.1 S/m） at which the s-SWNt heating rates dominated those of the m-SWNts. the heating effects were localized to aligned and aggregated ＂SWNt ropes＂ -1 cm in length that formed in suspension, parallel to the electric-field vector, during the RF exposure. For molarities above 1 mM, no enhancements were evident, owing to the large heating effects of the bulk ionic NaC1 suspensions, which were observed in previous studies. Although larger enhancement effects proportional to the host conductivity have been theoretically predicted for m-/s-SWNt suspensions, this was not observed most likely because of the aggregation and screening effects, which diminished the scattered electric field near the m-/s-SWNts. Our research may further the development of better nanoparticle heating agents for applications such as non-invasive RF-induced cancer hyperthermia.

Companies are currently immersed in a process of competitiveness, which is increasingly more complicated to achieve differentiation that can guarantee you the preference of customers and consequently the success of the organization. It becomes partly crucial for the organization to be in the dynamics of the sector and market where it operates and wants its consolidation, because value systems become strategic elemente that play a role as key factors of success in organizations seeking priority intend to increase their organizational performance. Given the above, this research seeks to get to identify strategic uses of information and communication technologies in the processes of the value chain in small commercial businesses in Mexicali, aiming to contribute to the improvement of the competitiveness of the same. It is in this sense that the technologies of information and communication have become a powerful tool that will allow them to be innovative, cost-effective and this will have an impact on the performance of the organization that will allow you to improve your service, interact with customers and suppliers, and above all more efficiently meet their own needs and organizational expectations. this research was exploratory and within the relevant findings, coming to the conclusion that it is necessary to focus more emphatically on the client; organizations have deficiencies in relation to the strategic use of ICts to streamline their billing, manufacturing, distribution, and storage of your products, activities highlighting this if they don＇t have a reconsideration in this aspect, at the risk of offset in terms of its competitors which would mean ceasing to be option on the market, stressing that this not only will be a trigger factor in mature companies, but those who need to improve their service and that they will serve as input for the conduction of processes along the value chain. the research is exploratory in nature, as evidenced in the use of the ICts

系统性红斑狼疮患者头痛患病率及其影响因素

Headache is common in systemic lupus erythematosus with reported prevalence as high as 70% . the aims of this study were: to estimate the prevalence and types of headache in a sample of patients with systemic lupus erythematosus comparing it with rheumatoid arthritis, to determine clinical and serological associations. Eighty- one systemic lupus erythematosus and 29 rheumatoid arthritis consecutive patients seen in our outpatient clinic were interviewed. Headache was evaluated using the diagnostic criteria proposed by the International Headache Society. Additional evaluations were carried out in the 81 systemic lupus erythematosus patients including depression, disease activity, lupus damage, function disability, quality of life, and severity degree using a validated scales. We analysed the following autoantibodies: anti- double stranded DNA, antinucleosomes, anti- histones, anti- ribosomal p, anti- cardiolipin antibodies, anti- β 2- glycoprotein- I (GpI), and antinuclear antibodies. Forty- one per cent of systemic lupus erythematosus and 17% of rheumatoid arthritis patients suffered from headache (p = 0.02). No significant difference for any primary headache type between the two groups was found. Frequency of headache types in systemic lupus erythematosus patients was: migraine 24% , tensional- type headache 11% , and mixed headache 5% . In systemic lupus erythematosus patients the risk factors associated with headaches were Raynaud’ s phenomenon (OR 3.6; 95% CI 1.3- 9.5; p = 0.009) and β 2GpI antibody positivity (OR 4.5; 95% CI 1.2- 16.2; p = 0.016). We conclude that headache is more common in systemic lupus erythematosus than in rheumatoid arthritis patients and was independently associated with Raynaud’ s phenomenon and β 2Gp- I antibodies.
