Experimental Analysis of Vortex Induced Vibration in the Bladeless Small Wind Turbine

Vortex-induced vibration is one of the predominant fundamental concepts for forced oscillation which attracts considerable practical engineering application for energy conversion. In this work, an oscillation of a mast arising as a result of wind force is utilized for energy conversion. The paradigm for energy conversion from vortex-induced vibration in the mast is the bladeless wind turbine. It consists of a rigid mass known as a mast, fixed in the spring of stiffness (k) and allowed to oscillate along the direction of the flow. In this work, four different types of mast have been fabricated and tested. The first is uniform tapered hollow conical mast (MAST1), the cross-section of the second is uniform tapered plus symbol (MAST2), the third is uniform tapered inversed plus symbol (MAST3) and the fourth is uniform tapered simple rectangular cross-section (MAST4). All the masts were fabricated using fiber carbon. The experiments were conducted in a versatile small wind turbine testing facility of Hindustan Institute of Technology and Science, Chennai. This test facility contained an open jet wind tunnel with variable frequency drive and other measuring instruments. The vibration sensor was located in the mast where it experienced a large oscillation in a free stream. In this experiment, an increase in wind velocity led to a terrible change in the amplitude of vibration. A vigorous oscillation was experienced in this mast at this critical frequency, when the natural frequency of the mast was synchronized with the frequency of the vortex shedding and the frequency of the oscillation of the mast. The total force in this oscillation was a summation of the body force due to the mass of the mast and vorticity force that is mainly which was the result of the shedding of the vortices. In this work, extensive studies have been carried out for Reynolds number ranging from 2.5 × 105 to 5.0 × 105. The mast length to diameter ratio of 13 was exposed to various speeds of wind and response was measured. The occurrence of the maximum oscillation in a simple rectangular mast was seen where vortex shedding due to the bluff body was large for constant mass and spring stiffness. The frequency of the oscillation at maximum amplitude of the rectangular cross-section mast was equal to the natural frequency, due to vortices shedding at critical velocity. This demonstrated the appropriateness of the simple rectangular cross-section for harnessing the low rated wind energy and its suitability for renewable energy conversion in the small bladeless wind turbine.
Evaluation of Rhodococcus equi Susceptibility to Silver Nanoparticle Antimicrobials

OF THESIS EVALUATION OF RHODOCOCCUS EQUI SUSCEPTIBILITY TO SILVER NANOPARTICLE ANTIMICROBIALS Rhodococcus equi is a significant cause of pneumonia in foals and immunocompromised humans. Antimicrobial resistance among R. equi isolates has developed as a consequence of inappropriate stewardship and bacterial evolution, leading to an increased rate of treatment failures that typically result in foal fatality. In the current study, we evaluated the efficacy of antimicrobial silver nanoparticle (AgNP) complexes in controlling R. equi growth. Previous studies characterizing AgNP-induced antibacterial effects in other Gram-positive pathogens led us to hypothesize that silver nanoparticle antimicrobials impact R. equi viability and intracellular replication. We therefore investigated the effect of silver nanoparticle complexes on R. equi growth; assessed whether silver nanoparticle complexes prevent intracellular replication of R. equi; and evaluated the safety of silver nanoparticles in host cells. The results presented here demonstrate that silver nanoparticle complexes exhibit bactericidal activity against R. equi. However, AgNP effective concentrations also induced rapid apoptosis and secondary necrosis of macrophage-like cells and equine pulmonary endothelial cells, suggesting multiple mechanisms of cytotoxicity. Overall, this study demonstrates that while silver nanoparticle-based therapeutics can effectively control R. equi proliferation, application of AgNP complexes as a treatment strategy for controlling rhodococcal disease may be limited by adverse host cellular effects.
Immunotherapy in Autoimmune Diabetes

Autoimmune diabetes is a chronic autoimmune disease caused by the loss or selective destruction of the insulin-producing cells, called pancreatic beta cells. Damage to beta cells results in an absence or insufficient production of insulin produced by the body. Most cases of autoimmune diabetes have an autoimmune basis, and the immune system mistakenly attacks and destroys beta cells. The immune system plays a critical role in controlling the development of autoimmune diabetes. Over the past years there have been significant progress and an accumulation of scientific evidence for the concept of immunotherapy. Immunotherapy for the prevention and treatment of autoimmune diabetes has become the main focus of the research community. Three regimens of immuno- therapy have been investigated: (1) Antigen-specific vaccines: Insulin-related molecules have attracted great interest in vaccine development, including the whole recombinant human GAD65 (rhGAD65) and the DiaPep277 peptide of HSP60. (2) Systemic immu- nomodulators: A large number of non–antigen-specific immunomodulators have been studied, including monoclonal anti-CD3 antibody, anti–CTLA-4 Ig, TNF-a, IFN-a, IL-1R antagonist, regulatory T cells, and dendritic cells. (3) Combination treatments: diabetes. Primary systemic immunosuppression followed by antigen-specific induction of tolerance or islet regeneration is a sound approach.
A gradient boosting approach to understanding airport runway and taxiway pavement deterioration

ABSTRACT Understanding airfield pavement deterioration is essential for airport asset management to ensure safe and efficient airport operations. This paper employs Gradient Boosting Machine (GBM) – a machine learning method – to investigate the contributions of a variety of influencing factors to runway and taxiway pavement deterioration at Chicago O’Hare International Airport. By adopting a systematic procedure consisting of model training, validation, and testing, two separate GBM models are developed to estimate Pavement Condition Index (PCI) of runways and taxiways. The models account for various input variables that are believed to affect pavement deterioration, including pavement age and material, maintenance and rehabilitation history, weather conditions, and air traffic loading effects. The developed GBM models are shown to outperform other methods (including linear regression, nonlinear regression, artificial neural networks, and random forest) in terms of model goodness-of-fit for both runway and taxiway pavements. The GBM modelling results are subsequently used to interpret the influence of individual input variables as well as their interactions on PCI, using relative importance and partial dependence plots. With promising results, the study demonstrates the use of an approach that was not previously considered in infrastructure management and can help airport agencies enhance the ability to understand airport asset performance.
All-fiber optical-self-injection stabilization of a frequency-comb quantum-dash laser

Intermode beat frequency and line-width stabilization of a 1 mm long self mode-locked frequency comb quantum dash laser emitting at 1535 nm by external all-fiber based single-cavity optical self-injection time-delay control is presented. Self-injection optical delay tuning is conducted by piezo-crystal single-mode fiber stretching. An intermode beat frequency control by 2 MHz and an intermode beat frequency line width reduction from 67 kHz to approximately 900 Hz is achieved. The experimental results are confirmed by an independent free-space stabilization experiment and stochastic time-domain modeling.
What are the Faculty Lecturers’ knowledge, Attitude and practice toward using social media's in nursing education and research?

Introduction : Social media(such as Yahoo mail, Gmail, Academic email, Facebook, YouTube, Twitter, Skype, Viber, Line, What's app, Telegram and…) has been used globally as a key vehicle for communication. Faculty workers and their roles have been reshaped and redefined by the integration of technology into the academic workplace and for facilitate their communication must be used social medias especially in education and research objectives. So the goal of this study is assessment of Faculty lecturers' knowledge, Attitude and practice toward using social media's in nursing education and research. Method and materials : This pilot study is a descriptive-analytic and questionnaire based with three dimensions (knowledge, attitude and practice of faculty lecturers about social media usage). The study participants were a total of 35 persons that 15 of them were nursing teachers and 18 of them were PhD students that co-operate with Razi nursing faculty of Kerman medical science university in third semester of 2015.after doing the validity and reliability of questionnaire (with responses of 10 PhD students before study and Cronbach alpha of internal correlation = 0.89) and after gathering data we used SPSS version 21 for analysis data.

A Literature Review of Intrathecal Morphine Analgesia in Patients Undergoing Major Open Hepato-Pancreatic-Biliary (HPB) Surgery

Context The optimal analgesic method for patients undergoing major open hepato-pancreatic-biliary surgery remains controversial. Continuous epidural infusion at the thoracic level remains the standard choice, however concerns have been raised due to associated complications. Single shot intrathecal morphine has emerged as a promising alternative offering similar analgesia with an enhanced safety profile. Evidence Acquisition This review aimed to evaluate the literature comparing intrathecal morphine analgesia to other analgesic modalities following major open hepato-pancreatic-biliary surgery. The primary outcome was pain scores at rest and on movement 24 h after surgery. Secondary outcomes were postoperative opioid consumption within 72 postoperative hours, length of stay (LOS), intra-operative fluid administration and post-operative fluid administration within 72 postoperative hours, and overall systemic complication rate within 30 postoperative days. Results Eleven trials matching the inclusion criteria were analysed. Intrathecal morphine resulted in equivalent or lower pain scores when contrasted to alternative techniques, but required higher amounts of postoperative opioid. Intrathecal morphine also offered reduced LOS and reduced fluid administration requirements to epidural analgesia, and there was no difference observed in major complication rate between analgesic modalities. Conclusions In summary the evidence suggests that intrathecal morphine may be a better first-line analgesic modality than epidural analgesia in the context of major open hepato-pancreatic-biliary surgery, but high-quality evidence supporting this is limited.
Middle matters : intermediaries and the practice of home energy retrofit

ion) theoretical ideas about skills and techniques with other actors who have the capacity to decode, adopt or reconfigure the skill (Shove et al., 2012). This all takes on particular relevance when contemplating the adoption of new ways of configuring a home in aid of reduced energy consumption. These might include conceptualizing the house as an interconnected system of materials, functions and technologies, novel ideas about framing exterior walls to minimize thermal bridging, or designing roofs to reflect, rather than absorb sunlight that might overheat a home's interior space. Thermal bridging for example, occurs when heat moves into or out of conditioned space via pathways formed by solid and contiguous materials with relatively higher thermal conductivity (Globe Advisors,
Hyperbolic CORDIC-Based Architecture for Computing Logarithm and Its Implementation

We present a CORDIC (Coordinate Rotation Digital Computer)-based method to compute the logarithm function with base 2 and validate this method by software simulation and hardware implementation. Technically, we overcome the limitation of traditional hyperbolic CORDIC and transform it based on the idea of generalized hyperbolic CORDIC so that it can be used to compute <inline-formula> <tex-math notation="LaTeX">$log_{2}x\;(x\;\epsilon \;[1,2))$ </tex-math></inline-formula>. The proposed method requires only simple shift-and-add operations and has a great tradeoff between precision (or speed) and area. In MATLAB, we provide different precisions corresponding to the iterations of the transformed CORDIC for user needs. Using a pipelined structure and setting the number of iterations to be 16 (the average relative error is <inline-formula> <tex-math notation="LaTeX">$2.09\times 10^{-6}$ </tex-math></inline-formula>), we implement an example hardware circuit. Synthesized under the SMIC 65nm CMOS technology, the circuit has an area of 24100 <inline-formula> <tex-math notation="LaTeX">$\mu m^{2}$ </tex-math></inline-formula> and computation time of 11.1 ns, which can save 31.04% area and improve 6.92% computation speed averagely compared with existing methods.
Investigation of Microbiota in Health and Disease of Poultry

The microbiotas play vital roles in health and diseases of both humans and animals. 16S rRNA genes sequence analysis is one of the most popular and commonly used methods in the analysis of microbiotas associated with hosts. In this dissertation, the microbiotas of chickens (broilers, breeders, and layers) and turkeys were evaluated by 16S rRNA gene sequencing. Characterization of the culturable subpopulations of Lactobacillus in the chicken gut can serve as a valuable resource for probiotic development. In Chapter 2, Lactobacillus subpopulations recovered on MRS from chicken gut were defined comprehensively for the first time using 16S rRNA gene profiling, where they varied with different regions (cecum vs. ileum) and locations (lumen vs. mucosa) with in the same region. In Chapter 3, we investigated the effect of cell densities as determined by varying levels of sample dilution on the culture-enriched microbiota profiles using MRS agar medium as a model system. The dilution levels of original samples was found to alter the resulting culture-enriched microbiota profiles via unknown density-dependent mechanisms. In chapter 4, Bacillus isolates (B. subtilis and B. amyloliquefaciens) were used to evaluate their therapeutic and prophylactic effects against Salmonella Enteritidis, and found their potentialities to reduce S. Enteritidis colonization and improve the intestinal health in broiler chickens possibly through altering the composition and functions of gut microbiota. In chapter 5, we investigated the cecal microbiota and egg production in two strains of Hy-Line (Brown and W36) housed in conventional cages (CC) and enriched colony cages (EC), and noticed differences in egg production and cecal microbiota between strains and housing types. In chapter 6, we performed a comprehensive survey of the litter microbiotas using booty swab samples in the 5 commercial turkey farms of the Northwest Arkansas. The litter microbiotas were found to differ between farms, and flocks which were further affected by the ages of turkeys. In Chapter 7, we developed and evaluated the nested TaqMan probe based qPCR assay for the quantitative detection of Clostridium septicum that targets the alpha toxin gene (csa).

DIREITO REGULATÓRIO COMPORTAMENTAL: VIDA SELVAGEM E SUSTENTABILIDADE NO CONTEXTO DA AGENDA 2030

O estudo parte da identificacao da baixa adesao as normas de protecao ambiental, o que fez com que a Organizacao das Nacoes Unidas elaborasse uma lista de objetivos para o atingimento do desenvolvimento sustentavel. Nessa conjuntura, constata-se que as normas juridicas ja postas nao sao suficientes para proteger o meio ambiente e a vida selvagem, especialmente em relacao a caca no Brasil. O prognostico que se visa confirmar e que a utilizacao de novos instrumentos postos ao legislador e ao regulador, pautados na compreensao da Economia Comportamental, que pode ser compreendida como um novo direito regulatorio comportamental, esta apta a trazer ganhos na protecao efetiva do meio ambiente e da vida selvagem, utilizando-se da nocao central de pressao social. Cass Sunstein e Richard Thaler, com a interligacao de direito e Economia Comportamental, servem de lastro teorico para investigar a aplicacao do que conceituaram como paternalismo-libertario e sua viabilidade nesta nova categoria de direito a ser produzida âmbito da regulacao ambiental, neste vies comportamental. Conclui-se que essa nova fase da regulacao, para alem das normas deonticas e do soft law, traz uma complementacao a esses modelos ja consagrados (dever-ser e analise do custo-beneficio), possibilitando novas estrategias para que se atinjam com eficacia as metas da Agenda 2030 para o desenvolvimento sustentavel, o respeito a vida selvagem e ao meio ambiente.
Womens Status, Household Structure and the Utilization of Maternal Health Services in Haryana (India)

In developing world, women suffer from complications of pre gnancy and delivery and maternal health care service utilization is much below the acceptable level. Maternal an d child welfare goals couldnt be achieved without improving the status of women in the family and society as well. An effort has been mad e in this study to assess the effect of womens status, and hous e ld structure on utilization of maternal health care services i n Haryana. Methods:Data was taken from the third round of National Family Health Survey (NFHS-III) which is a national representative survey of women in the 15-49 years age groups. The sample used for this study comprised those women who had at least one birt h in five year prior to the survey. To estimate the effect of the wom ens status and household structure variables on maternal he alth s rvice utilization three outcome variables were used which were us e of antenatal care services, place of delivery and use of ass ist nce during delivery by health professional. Moreover, dichotomous va riable i.e. place of residence was used to control for the acc ssibility and availability of maternal health services. Logistic regres sion technique was practiced to estimate models of the outco me variables. Separate models were also done for the urban and rural women s ince this group differs in many ways. In addition to this a pro bability model was done to estimate the probability of use of the servi c s by selected variables from the logistic regression mode l. Result:The result showed that only 34% of the women births in India ta ke place in health facilities while 66% received assistance during delivery from skilled provider. Utilization of mate rnal health services was significantly low among rural women as compared to their urban counterparts. In the logistic regression model e ucational status of the mother, maternal autonomy and hou se ld wealth were found to be strong indicators of utilization of materna l health care services in Haryana. Antenatal care use was fou nd to be a strong indicator of place of delivery and received assistan ce during delivery by a skilled provider. Women with seconda ry/higher level of education have substantially higher probabilities of re ceiving assistance from a modem source at delivery compared with women with primary education. Conclusion:-To increase womens utilization of basic health care service s and improve maternal health in Haryana some crucial steps should be taken on educating women and strengthening antena tal care services. Great attention should be given to the mos t vulnerable group of women in the state this includes those who are living in rural areas with no education and in the low economic statu group.
Do steroids trigger mania in multiple sclerosis? Not always!

Bipolar disorder and MS co-occur at a relatively higher rate. A 25-year old woman with a 7-year history of MS was admitted to our hospital with right side weakness. During the examination, she showed some manic behavior patterns and diagnosed as ‘bipolar disorder-manic episode’ by her psychiatrists. She was recommended for high dose steroids for her attack and antipsychotics for the manic episode but she refused the latter. Unexpectedly at the third day of steroid treatment, instead of being exacerbated, almost all of the manic symptoms disappeared. In the literature, this is the first report of a MS patient with bipolar disorder whose manic symptoms were cured after receiving steroids. (Turkish Journal of Neurology 2015; 21:68-70)
