Single-Phase Inverter-Control Techniques for Interfacing Renewable Energy Sources With Microgrid—Part II: Series-Connected Inverter Topology to Mitigate Voltage-Related Problems Along With Active Power Flow Control

In this paper (Part II), a control strategy for a single-phase series-connected inverter with the microgrid is proposed to interface ac loads not only to regulate the load voltage under voltage disturbances, but also to control the load power drawn from the microgrid. The inverter compensating voltage works in such a way that, irrespective of any type of disturbances in the microgrid voltage (such as sag, swell, or harmonic distortions), the load voltage is maintained at its rated voltage level with low total harmonic distortion (THD) in voltage. The proposed control strategy also facilitates a specific amount of active power flow (from renewable energy source) to the load irrespective of the microgrid voltage condition. The rest of the load power is supplied by the microgrid. To facilitate this control strategy, a spatial repetitive controller (SRC) is proposed and implemented in microgrid phase (θ) domain to make the controller independent of the microgrid frequency. The proposed controller ensures dynamic stability of the system even if there is a sudden change in the microgrid frequency. Detailed experimental results are presented to show the efficacy of the proposed series inverter system along with the controller under different operating conditions.
Personalisation and the future of adult social care: the views of Hampshire residents, submitted to the Hampshire County Council Commission of Inquiry

The personalisation agenda and the crisis in social care funding necessitate major reshaping of the adult social care system. ‘Putting People First’ requires that, by 2011, adult social care services undergo a transformation, facilitating greater choice and control for the individual and a more personalised response to their care and support needs. To help determine its approach to transformation, Hampshire County Council created a Commission of Inquiry. To find out people’s experiences of social care in relation to the personalisation agenda, their ideas on the way forward to transform services and their views on how care should be paid for in the future, the Commission put out a call for evidence across the County. This article identifies key messages submitted in response by Hampshire residents and local organisations. It highlights issues that need to be dealt with to meet the personalisation agenda including: paternalism; the relevancy of current services; provider fears; regulation; partnership; the lack of preventative services; lack of information and advice. The article reveals the diversity of views on how care should be funded. It concludes that local authorities should be mindful of the importance of engaging all stakeholders in partnership at the beginning of the process to take forward the agenda.
In vitro modulation of primate coronary vascular muscle cell reactivity by ovarian steroid hormones

Susceptibility to drug‐induced coronary vasospasm in rhesus monkeys increases after removal of the ovaries and can be normalized by adding back physiological levels of estradiol‐17β (E2) and/or natural progesterone (P) in vivo as reported recently by our group. Furthermore, the reactivity status (Ca2+ and protein kinase C responses) of freshly isolated and primary culture coronary artery vascular muscle cells (VMC) mimic the intact coronary artery responses to 5‐HT + U46619. Since coronary reactivity is maintained in the isolated VMC, we hypothesized that the reactivity state inherent in the VMC was modulated directly by ovarian steroids in vitro as in the whole animal. To test this hypothesis, we treated hyperreactive VMC from ovariectomized (ovx) monkeys in vitro with E2 or P and measured VMC reactivity to combined stimulation with 5‐HT and U46619, as determined by the amplitude and especially the duration of intracellular Ca2+ signals, as well as protein kinase C (PKC) activation/translocation. VMC were treated for 12–96 h with 3–100 pg/ml E2 (10–365 pM) and/or 0.3–3 ng/ml P (0.95–9.5 nM). Hyperreactive responses to the combination of 5‐HT and U46619 in untreated VMC were significantly and dose‐dependently reduced by treatment in vitro with physiological levels of either E2 or P for at least 24 h. Both the early transient and late sustained increases in intracellular Ca2+ and PKC translocation were blunted, and the effects of 0.2 nM E2 and 3.2 nM P were specifically antagonized by the receptor blockers ICI 182,780 (200 nM) and RU486 (15 nM), respectively. Antibodies to the estrogen receptor and progesterone receptor labeled nuclei in VMC, which were also positively labeled by a smooth muscle myosin heavy chain monoclonal antibody. These data indicate that natural ovarian steroids directly reduce hyperreactive 5‐HT and thromboxane A2‐stimulated Ca2+ and PKC responses of coronary artery VMC from surgically menopausal rhesus macaques. We hypothesize that vascular hyperreactivity, which may be a critical factor involved in the increased incidence of coronary artery vasospasm and ischemic heart disease in postmenopausal women, can be normalized by E2 and/or P through direct actions on coronary artery vascular muscle cells. —Minshall, R.

Natural Resource Booms in the Modern Era: Is the Curse Still Alive?

The global boom in hydrocarbon, metal and mineral prices since the year 2000 created huge economic rents - rents which, once invested, were widely expected to promote productivity growth in other parts of the booming economies, creating a lasting legacy of the boom years. This paper asks whether this has happened. To properly address this question the empirical strategy must look behind the veil of the booming sector because that, by definition, will boom in a boom. So the paper considers new data on GDP per person outside of the resource sector. Despite having vast sums to invest, GDP growth per-capita outside of the booming sectors appears on average to have been no faster during the boom years than before. The paper finds no country in which (non-resource) growth per-person has been statistically significantly higher during the boom years. In some Gulf states, oil rents have financed a migration-facilitated economic expansion with small or negative productivity gains. Overall, there is little evidence the booms have left behind the anticipated productivity transformation in the domestic economies. It appears that current policies are, overall, prooving insufficient to spur lasting development outside resource intensive sectors.
Rotor cage faults detection in induction motors by Motor Current Demodulation Analysis

Dynamic rotor faults of induction motors, mainly broken or cracked rotor bars and dynamic rotor eccentricity, cause stator currents modulation. The detailed motor current analysis revealed meaningful phase modulation and its relation to amplitude modulation at increasing motor load and inertia load It is shown, that by increasing motor load mainly phase modulation increases and by increasing inertia load a phase shift between both modulations currents changes. This influences the MCSA spectral sidebands amplitudes and therefore it is not possible to determine the real fault size. The paper introduces a new method of motor current amplitude demodulation analysis -MCDA and shows that spectral amplitudes almost do not change with increasing load and inertia load Moreover MCDA directly analyzes fault signals without great motor stator current and increases resolution both in amplitude and frequency domains, facilitates and precises evaluation. Two demodulation methods using Hilbert transform and space transform are introduced
Wireless sensor networks and safe protocols for user tracking in human-robot cooperative workspaces

Workers protection in collaborative industrial robotics application represents the predominant aspect of robot safety in production systems. Flexible production systems and multimodal human-robot interactions often encompass cooperative tasks that are performed in fenceless configurations. Collaborative open workspaces enable, in fact, a workflow of continuously interchangeable tasks done by operators or by robot at close distance or using hand-guided modes. Layout and workflow optimization may, in fact, require a co-presence in some shared spaces whose safeguarding (e.g. robot speed limitations, distances) is conservatively restricted by the current standards. In such scenarios, the tracking of operators is mandatory for the overall assessment of the system safety. In this work, a combination of wireless sensing technologies, highly robust wireless protocols and safe computation over a standard ethernet IP (black channel) concur to improve the functional safety of a cooperative robotic system. The system architecture and data framework are in particular discussed with reference to the properties of the communication protocols implementing the safety layer.
Improvement of Contractile Function in Isolated Cardiomyocytes From Ischemia-Reperfusion Rats by Ginkgolide B Pretreatment

Ginkgo biloba extract is an important natural product for treatment of cerebral and cardiovascular diseases, whereas ginkgolide B (GB) is a main component of it. Its effects on ischemic heart and ventricular contractile function in Sprague-Dawley male rats are unclear yet. In the present study, we investigated the function of isolated hearts subjected to ischemia-reperfusion (IR) with or without GB pretreatment by using Millar transducer instruments. We also tested the left ventricular cardiomyocyte shortening amplitude after IR with different concentrations of GB pretreatment for 0.1, 1.0, 2.0, 5.0, and 10.0 μM. The infarct size was tested by triphenyltetrazolium chloride. The release of lactate dehydrogenase (LDH) in the coronary effluent was determined with LDH kit. The expressions of Bcl-2 and Bax were assessed by Western blotting. We found that GB improved the function of left ventricle from IR injury and decreased infarct size and the release of LDH. The cardiomyocyte shortening amplitude depended on different concentrations of GB, which increased significantly at 2.0 μM GB (P < 0.01). The expression of protein Bcl-2 was upregulated by GB and the ratio of Bax to Bcl-2 was decreased by GB. Our results showed that GB can partly prevent IR injury in rat heart.
Funding Resilient Infrastructure in New Jersey: Attitudes Following a Natural Disaster

Recent major natural disasters in New Jersey have demonstrated the need to increase 33 the resilience of transportation infrastructure. This research examines public attitudes 34 towards revenue sources that can be dedicated to protecting vulnerable areas, most 35 notably the transportation linkages on which the state depends. A statewide survey was 36 conducted to gather data about four months following Superstorm Sandy, the costliest 37 natural disaster in the state’s history. The authors' objective was to sample public attitudes while 38 the impacts of the disaster were still fresh. The authors found little support for temporary tax 39 increases to improve resiliency, with the most positive support for taxing visitors (i.e., a 40 hotel and recreational tax) and for a 30-year bond measure (i.e., taxing the future). This 41 observation seemingly contradicts broad support for investing in new infrastructure, as 42 well as maintaining and protecting existing infrastructure. Multivariate analysis to 43 understand the underlying attitudes towards raising revenue found that more left-leaning 44 or communitarian attitudes are associated with more support for gasoline, income, or 45 sales taxes devoted to improving vulnerability. Those who supported investment in 46 transit and protecting infrastructure also were more likely to support these taxes. There 47 was no parallel finding of factors associated with taxing visitors or issuing bonds.
A simple vascular calcification score predicts cardiovascular risk in haemodialysis patients.

BACKGROUND Cardiovascular morbidity and mortality are highly prevalent in haemodialysis (HD) patients and have been recently associated with vascular calcifications. The objective of our study was to assess the value of a simple vascular calcification score for the prediction of cardiovascular death, cardiovascular hospitalizations and fatal and non-fatal cardiovascular events in HD patients, and to correlate this score with cardiovascular disease and with other known predictors of vascular disease. METHODS In this observational, prospective study 123 chronic HD patients (75 males and 48 females; 20% diabetic) were included, who were on low-flux HD treatment for 46.6+/-52 months (mean+/-SD). We set up a simple vascular calcification score based on plain radiographic films of pelvis and hands. Brachial pulse pressure and mean arterial pressure (MAP) were measured and cardiovascular events and hospitalization episodes were assessed. RESULTS During an observational period of 37 months there were 17 cardiovascular deaths; 28 patients needed cardiovascular hospitalizations and 32 patients suffered fatal and non-fatal cardiovascular events. Coronary artery disease was diagnosed in 43 patients (35%), peripheral arterial disease in 33 patients (26.8%), cerebrovascular disease in 16 patients (13%) and vascular disease (coronary artery disease or peripheral arterial disease or cerebral vascular disease) in 61 patients (49.6%). By binary logistic regression, diabetes (P = 0.01), male sex (P<0.001), age (P = 0.02), HD duration (P = 0.02) and MAP (P = 0.03) were independently associated with a vascular score > or =3. This score > or =3 was independently associated with coronary artery disease (P = 0.008), peripheral arterial disease (P<0.001) and vascular disease (P = 0.001). Patients with a vascular calcification score > or =3 had a 3.9-fold higher risk of cardiovascular mortality (P = 0.03), a 2.8-fold higher risk of cardiovascular hospitalizations (P = 0.02) and a 2.3-fold higher risk of fatal or non-fatal cardiovascular events (P = 0.04). CONCLUSIONS The present vascular calcification scoring represents a simple tool for the assessment of cardiovascular risk related with vascular calcifications in chronic HD patients.
Software as a Service - Common Service Bus (SAAS-CSB)

Software-as-a-Service (SaaS) is a form of cloud computing that relieves the user from the concern of hardware, software installation and management. It is an emerging business model that delivers software applications to the users through Web-based technology. Software vendors have varying requirements and SaaS applications most typically support such requirements. The various applications used by unique customers in a single instance are known as Multi-Tenancy. There would be a delay in service when the user sends the data from multiple applications to multiple destinations and from multiple applications to single destination due to the use of single CSB. This problem can be overcome by using multiple CSB concepts and hence multiple senders can efficiently send their data to multiple receivers at the same time. The multiple clouds are monitored and managed by the SaaS-CSB portal. The idea of SaaS-CSB Portal is to provide a single pane of glass for the user to consume and govern any service from any cloud. Thus, SaaS-CSB application allows companies to save their IT cost and valuable time.
Stability of extemporaneously prepared rifaximin oral suspensions.

PURPOSE The stability of extemporaneously prepared rifaximin oral suspensions was studied. METHODS An oral suspension of rifaximin 20 mg/mL was prepared by thoroughly grinding six 200-mg tablets of rifaximin in a glass mortar. Thirty milliliters of Ora-Plus and 30 mL of either Ora-Sweet or Ora-Sweet SF were mixed and added to the powder to make a final volume of 60 mL. Three identical samples of each formulation were prepared and placed in 2-oz amber plastic bottles with child-resistant caps and were stored at room temperature (23-25 degrees C). A 1-mL sample was withdrawn from each of the six bottles with a micropipette immediately after preparation and at 7, 15, 30, and 60 days. After further dilution to an expected concentration of 20 microg/mL with mobile phase, the samples were assayed in duplicate using stability-indicating high-performance liquid chromatography. The samples were visually examined for any color change and pH was tested on each day of analysis. Stability was determined by evaluating the percentage of the initial concentration remaining at each time point and defined as retention of at least 90% of the initial concentration of rifaximin. RESULTS At least 99% of the initial rifaximin remained throughout the 60-day study period in both preparations. There were no detectable changes in color, odor, taste, or pH and no visible microbial growth in any sample. CONCLUSION Extemporaneously prepared suspensions of rifaximin 20 mg/mL in 1:1 mixtures of Ora-Plus with either Ora-Sweet or Ora-Sweet SF were stable for at least 60 days when stored in 2-oz amber plastic bottles at room temperature.
Association of –2548 G/A Polymorphism in the Leptin Gene with Preeclampsia/Pregnancy-Induced Hypertension

Objectives. To investigate −2548 G/A polymorphism of LEP gene, plasma leptin and soluble leptin receptor in preeclampsia/pregnancy induced hypertension. Methods. Sixty-two patients and 63 controls (normal pregnancies) studied in the third trimester. Leptin and soluble leptin receptor measured by enzyme immunosorbent assay and −2548 G/A polymorphism by polymerase chain reaction followed by restriction enzyme digestion. Results. Frequency of the AA genotype was significantly (p < 0.001) higher in patients. The A allele conferred a relative risk of 1.67 for the disease (p < 0.0001). Preeclampsia/pregnancy induced hypertension significantly (p < 0.001 to 0.0001) affected leptin and soluble leptin receptor concentrations, free leptin index and leptin normalized to body mass index. Genotype significantly (p < 0.05) influenced only the soluble leptin receptor concentrations. Conclusions. Preeclampsia/pregnancy induced hypertension appears to be associated with higher circulating leptin and lower SLR levels, and with the AA genotype of −2548 G/A polymorphism of the leptin gene.
Application of non-intrusive polynomial chaos expansion in probabilistic power flow with truncated random variables

In this paper, the authors apply a surrogate model-based method for probabilistic power flow (PPF) in the power system subject to truncated random variables. Due to a growing number of uncertainty sources are being brought into the modern power system, the traditional deterministic power flow analysis lacks its ability to recognize the realistic states of power systems, and thus turns to PPF for help. However, the PPF analysis is still facing several challenges: the computational effort required by the traditional simulation method is prohibitively expensive; and the modeling of uncertainty sources needs the improvement on both distribution type selection and parameter evaluation. The novelty of this work lies in taking advantage of both general polynomial chaos (gPC) expansion and ordinary least squares (OLS) to deal with PPF in presence of the truncated random variables. The performance of the proposed method is verified on the IEEE 30-Bus test system, considering uncertain factors brought by active power at load buses. In different test scenarios, the proposed method shows sound performances at the cost of less computational effort, compared to the traditional approach.
Statistical characterization of the dynamic human body communication channel at 45MHz

The dynamic human body communication (HBC) propagation channel at 45 MHz was statistical characterized in this paper. A large amount of measurement data has been gathered in practical environment with real activities -treadmill running at different speeds in a lab room. The received power between two lower legs was acquired from three volunteers, with more than 60,000 snap shot of data in total. The statistical analyses confirmed that the HBC propagation channel at 45 MHz followed the Gamma and Lognormal distributions at the slower (2 km/h and 4 km/h) and faster (6 km/h and 8 km/h) running activities, respectively. The channel is insensitive to body motion with the maximum average fade duration is 0.0413 s and the most averaging bad channel duration time being less than 60 ms with the percentage of the bad channel duration time being less than 4.35%.
Biochemical Targets of the Isoflavone Genistein in Tumor Cell Lines

Abstract Dietary intake of soy is associated with a decreased risk of both hormone-dependent and hormone-independent cancers. It has been proposed that genistein, the predominant isoflavone in soy foods, is responsible for this effect. In this review, the potential mechanisms of action of genistein at the cellular level are critically examined to determine which are physiologically relevant. We concluded that (i) only those mechanisms requiring genistein concentrations below 5 μg/ml (18 μM) should be considered, and (ii) more emphasis should be placed on the effects of genistein on events in normal cells or those from the early stages of the cancer process.

Multiscale feature detection of multispectral remotely sensed imagery in wavelet domain

This paper develops a new representation to detect the edge features on multispectral remotely sensed imagery which is based on the concept of combining dyadic wavelet transform of Mallat with first fundamental form. The dyadic wavelet transform can be applied to produce the multiscale edge detection, and making use of the first fundamental form is for edge detection of multispectral images. The representation provides a local measure for the contrast of a multispectral image at different scales. A variety of experiments by using the IKONOS images and Quick Bird images of Nanjing area are presented to demonstrate the representation efficient. It is shown from the results that the edge information of the objects, i.e. road, factory, paddy, can be detected clearly from coarse to fine at different scale levels. The technique of detecting edge information on the multispectral image is demonstrated to be beneficial to using the numerous data of multispectral remotely sensed imagery. And the multiscale edge detection method paves the way for developing the applications of object-oriented method in remote sensing.
