A Review of Strategies to Increase PV Penetration Level in Smart Grids

Due to environmental concerns, power system generation is shifting from traditional fossil-fuel resources to renewable energy such as wind, solar and geothermal. Some of these technologies are very location specific while others require high upfront costs. Photovoltaic (PV) generation has become the rising star of this pack, thanks to its versatility. It can be implemented with very little upfront costs, e.g., small solar home systems, or large solar power plants can be developed to generate MWs of power. In contrast with wind or tidal generation, PV can be deployed all around the globe, albeit with varying potentials. These merits have made PV the renewable energy technology with highest installed capacity around the globe. However, PV penetration into the grid comes with its drawbacks. The inverter-interfaced nature of the PV systems significantly impacts the power system operation from protection, power flow and stability perspectives. There must be strategies to mitigate these negative impacts so that PV penetration into the grid can continue. This paper gives a thorough overview of such strategies from different research fields: such as communication, artificial intelligence, power electronics and electric vehicle charging coordination. In addition, possible research directions are given for future work.
Effects of rumen-protected methionine supplementation on growth performance, nitrogen balance, carcass characteristics, and meat quality of lambs fed diets containing buckwheat straw

Abstract: This study was conducted to determine the effects of rumen-protected methionine (RPM) supplementation on growth performance, nitrogen (N) balance, carcass traits, and meat quality of lambs fed diets containing buckwheat straw. Twenty male Tan lambs from Ningxia were housed in individual pens and were randomly assigned to five dietary treatments that were supplemented with RPM at levels of 0 (control), 1.5 (T1), 3.0 (T2), 4.5 (T3), and 6.0 g d-1 (T4). Dry matter intake was higher in T4 than control (P < 0.05). The feed:gain ratio generally reduced with increasing dietary RPM, but the lowest ratio was found in T3 (P < 0.05). Dry matter digestibility and N retention were highest in T3 (P < 0.05) while N excretion was the lowest. Carcass fat weight and grid reference tissue depth increased while drip loss decreased by supplemental RPM, and significant differences were found between T4 and control (P < 0.05). However, pH, color, cooking loss, and shear force were not affected. The results from this study demonstrated that dietary RPM supplementation may be able to improve the feed efficiency, N utilization, and meat quality of lambs; however, the optimal dose of RPM needs to be explored further.
Influential factors and barriers to opt for the uptake of HIV testing among the adult population at HIV-care admission in an area in the DR Congo: What can we learn?

Introduction: To reverse the trends of the acquired immune deficiency syndrome (AIDS) epidemic, reinforcement of personal protection and antiretroviral treatment (ART) initiation at right time are needed. The aim of the study was, a decade after expanding AIDS medical care, to explore facilitating factors or those contributing to uptake or delay of human immunodeficiency virus (HIV) testing among individuals who access voluntary counselling and testing (VCT) in an urban area of the Democratic Republic of Congo (DRC). Material and methods: A cross-sectional survey carried out among individuals attending three VCT centres in Kinshasa, DRC. Results: A total of 388 individuals with mean age 42 (9.4) years were included. Among them 34% were married, and 96% were living at home. Morbid and social events were the most important reasons cited for uptake of HIV testing in urban areas. Among the most common barriers of the HIV testing observed, stigma was the first reason significantly prevalent cited among man while fear to know the HIV status, ignorance of seropositivity concepts and the existence of VCT screening were prevalent among females. Conclusions: Two main events influencing the uptake of HIV testing and commonly known barriers to this were cited. These results generate questions about a fringe of the population, and call for further research for improved prevention policy.

The effect of self-selected music on shooting performance among young female adults

Music has been widely used in our daily life and has been particularly useful in sports and exercise settings. Many researchers have explored the benefits and different types of music during sports activity and athletic performance. This study aims to investigate the effect of self-selected music on shooting the performance and the preferred type of music they listen to during the task. This is a quasi-experimental study done among 46 female netball players. They were asked to complete 12 trials shots at three different positions in front of the netball post. They were needed to complete the shooting trial under two conditions, with and without music within a one-week interval between the two conditions. Following the completion of the shooting performance, participants were needed to rate the motivational qualities of their selected music using the Brunel Music Rating Inventory-2 (BMRI-2) questionnaire. The result shown no significant differences between the two conditions on the participants' shooting performance (p>0.05), and most of the participants preferred to use fast type music compared to slow and medium music during the sports activity. Listening to music during the shooting performance didn’t improve their skill even with the use of the participants’ selected motivational music.
Multidisciplinary Application of an External Tissue Expander Device to Improve Patient Outcomes: A Critical Review

Significance: Continuous external tissue expansion (CETE) is a versatile tool in soft tissue injury management, and could be an addition to the traditional reconstructive ladder. Recent Advances: This critical review discusses the principles and application of CETE, covering a company-sponsored consensus meeting on this emerging technology and highlighting the DermaClose® (Synovis Micro Companies Alliance, Inc., Birmingham, AL) device's unique approach to soft tissue injury management. There is clinical evidence to support the use of CETE in the management of a number of wound types, including fasciotomy, trauma, amputation, and flap donor sites. The device can be applied to open wounds, potentially avoiding the need for a skin graft or other more complex or invasive reconstruction options. DermaClose applies constant tension without restricting blood flow and does not require repeated tightening. Critical Issues: CETE is becoming more widely used by surgeons of different specialties, and numerous reports describing its efficacy and safety in wound management have been published. Surgeons using CETE must follow the correct technique and select patients carefully to achieve optimal outcomes. However, there is no single source of information or consensus recommendations regarding CETE application. Future Directions: Prospective evidence on the efficacy and safety of CETE in clinical practice is required to communicate the best techniques and share important experiences. This will help to solidify its place in the reconstructive ladder as a valuable additional option for surgeons.

First we study these cases at and then at .
Analysis and Design of an LCCC/S-Compensated WPT System With Constant Output Characteristics for Battery Charging Applications

The wireless power transfer (WPT) system has been extensively studied for its safety, convenience, and esthetics and has gradually been introduced into our life applications. In order to maintain battery performance, constant-current (CC) and constant-voltage (CV) charging outputs are generally regarded as the dominant charging modes. However, battery equivalent resistance changes significantly during the charging, so it is difficult to simultaneously achieve load-independent CC and CV charging outputs and zero phase angle (ZPA) condition. This article proposes a new LCCC/S topology and its corresponding parameter tuning method to obtain CC and CV charging modes at two different ZPA operating frequency points, respectively. In addition, it is worth mentioning that the receiver has only one compensation capacitor, which follows the principle that the receiver of the WPT system should remain compact and portable. Furthermore, a simple frequency modulation controller is designed to solve the problem of inaccuracies of the charging outputs due to parasitic losses of components and fluctuations of dc input voltage. Finally, a verification setup with 3-A output current in the CC mode and 48-V output voltage in the CV mode was built to validate the feasibility and rationality of the proposed LCCC/S-compensated WPT system and the corresponding control method.
Environment Sensing Based on Non-Geotagged Sensor Data

In this paper, we investigate the feasibility of environment sensing with non-geotagged sensor data. There is a need for such environment sensing with non-geotagged data to reduce the data volume and power consumption of rapidly growing networks of connected devices. We propose a straightforward method using proximity-based localization to first obtain sensor’s relative locations, and then applying a transformation to obtain their absolute locations using anchor sensors, whose location are known. First, sensors for detecting the target objects are deployed in an observation area. Each sensor transmits data including the sensor identifier to a cloud server when it detects an object nearby. The data from each sensor are not geotagged and the locations of sensors are not known in advance. In this work, we show that the information about the objects (e.g., the number of objects) in the field can be obtained by localizing the sensors based on their responses to the objects traversing the field. The key idea is that sensors simultaneously detecting the target object are in close proximity. Each time an object traverses the field, it provides information on the relative locations of the sensors. Based on the information on the relative locations of the sensors, a map of the relative or absolute locations of sensors can be constructed by solving a nonlinear optimization problem. Once the sensor location map is constructed, we can then obtain information on the objects in the field. We demonstrate the feasibility of the proposed approach with simulation experiments.
Sexually dimorphic responses to MPTP found in microglia, inflammation and gut microbiota in a progressive monkey model of Parkinson’s disease

Inflammation has been linked to the development of nonmotor symptoms in Parkinson’s disease (PD), which greatly impact patients’ quality of life and can often precede motor symptoms. Suitable animal models are critical for our understanding of the mechanisms underlying disease and the associated prodromal disturbances. The neurotoxin 1- methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated monkey model is commonly seen as a “gold standard” model that closely mimics the clinical motor symptoms and the nigrostriatal dopaminergic loss of PD, however MPTP toxicity extends to other nondopaminergic regions. Yet, there are limited reports monitoring the MPTP-induced progressive central and peripheral inflammation as well as other nonmotor symptoms such as gastrointestinal function and microbiota. The main objective of this study is to gain a broader understanding of central and peripheral inflammatory dysfunction triggered by exposure to a neurotoxicant known to degenerate nigral dopaminergic neurons in order to understand the potential role of inflammation in prodromal/pre-motor features of PD-like degeneration in a progressive non-human primate model of the disease. We measured inflammatory proteins in plasma and CSF and performed [18F]FEPPA PET scans to evaluate translocator proteins (TSPO) or microglial activation in a small cohort of rhesus monkeys (n=5) given weekly low doses of MPTP (0.2-0.8 mg/kg, im). Additionally, monkeys were evaluated for working memory and executive function using various behavior tasks and for gastrointestinal hyperpermeability and microbiota composition. Monkeys were also treated with novel TNF inhibitor XPro1595 (10mg/kg, n=3) or vehicle (n=2) every three days starting 11 weeks after the initiation of MPTP to determine whether nonmotor symptoms are tied to TNF signaling and whether XPro1595 would alter inflammation and microglial behavior in a progressive model of PD. Our analyses revealed sex-dependent sensitivity to MPTP that resulted in early microglial activation by PET, acute plasma IL-6 and CSF TNF, and earlier parkinsonism as measured by motor deficits in males compared to female monkeys. Sex differences were also identified in microbiota and their metabolites and targeted short chain fatty acids at both basal levels and in response to MPTP. Both sexes displayed cognitive impairment prior to a significant motor phenotype. Importantly, XPro1595 shifted peripheral and central inflammation, and significantly reduced CD68-immunoreactivity in the colon. As such, our findings revealed a sexually dimorphic inflammatory response to chronic MPTP treatment and suggest that males may have higher vulnerability than females to inflammation-induced degeneration. If these findings reflect potential differences in humans, these sex differences have significant implications for therapeutic development of inflammatory targets in the clinic.
An Analysis of Female Identity Construction in English Advertisements

Advertisement has become an important medium for commercial promotion. The construction of female identity in advertisement has been a controversial topic among scholars at home and abroad. The discrimination in advertisements shows problems in the construction of female identity in advertisements. Although a number of studies have examined female identity and identity construction mainly in literary works, films and television, they receive little attention in the field of English advertisements. This paper analyzes problems and reasons for the construction of female identity in English advertisements, and discuss how to construct female identity from three aspects of the relationship between discourse and identity, the relationship between power and identity and self-identity consciousness. This study can raise awareness of the problem of gender discrimination in advertisements today, as well as women’s status in society and equality in gender relations. This study mainly focuses on the register of English advertisements and conducts case studies, and explores how to construct the female identity in the advertisements.

RESUMEN: El objetivo del estudio fue describir las características anatómicas y establecer hipótesis morfo-funcionales del esqueleto del miembro torácico de Mazama gouazoubira . Para ello, se utilizaron los miembros torácicos de cuatro adultos jóvenes. Los huesos se prepararon mediante ebullición y fueron blanqueados en una solución de peróxido de hidrógeno para obtener descripcion s comparativas, mediciones osteométricas y radiografías digitales. En comparación con los rumiantes domésticos, la escápula resul tó ser ancha y plana, con el acromion pequeño, el proceso coracoides muy pequeño y sin tuberosidad de la espina. El húmero se observó alargado con la diáfisis redondeada en una sección transversal y con proyecciones no articulares lisas. La ulna se unió al radi o hasta la epífisis distal y juntos formaron un espacio interóseo proximal alargado y estrecho, sin surco vascular. El esqueleto de la man o pr sentó los metacarpianos III y IV bien desarrollados y fusionados, mientras que los metacarpianos II y V resultaron rudimentarios con disp sición telemetacarpiana, filogenéticamente típico de cérvidos del Nuevo Mundo. Se encontraron cuatro dedos con tres falanges en cad uno, de los cuales, dos corresponden a los principales (III y IV) que llegan al suelo y dos son rudimentarios (II y V). Las rad iografías nos permitieron visualizar los patrones de tensiones trabeculares normales y la osteometría permitió establecer relaciones con fines comparativos. Se reconocieron las adaptaciones esqueléticas del miembro torácico para favorecer la locomoción cursorial saltato ria.
Mecanismos de funcionamento das cirurgias anti-obesidade Operational mechanisms of anti-obesity surgeries

Surgery is the long-term effective treatment for morbid obesity. The mechanisms of action could vary relating to the surgical technique employed. The gastric bypass is based in the reduction of plasmatic levels of ghrelin for post-prandial saciety. In disabsortive methods (as in Scopinaro and Duodenal Switch) the intestinal hormonal changes plays the dominant factor. There is marked increase of GLP1, GLP2 and PYY, with reduction of GIP. Regarding to type 2 Diabetes reversion, the entero-insular axis changes (due to duodenal jejunal exclusion) with elevation of GLP1 secretion has a prominent role.
Meningitis Neonatal Precoz causada por transmisión vertical de Escherichia coli productora de beta-lactamasa de espectro extendido en parto prematuro con rotura prematura de membranas

Se comunica el caso de un recién nacido producto de un parto prematuro con rotura prematura de membranas, que desarrolló precozmente meningitis neonatal por Escherichia coli productora de beta-lactamasa de espectro extendido. Los cultivos en líquido céfalo raquídeo y sangre neonatal fueron tempranamente positivos para esta bacteria. No obstante no aislarse este microorganismo en la madre, los hallazgos de la biopsia placentaria y la precocidad de la infección neonatal son determinantes en señalar que se trató de infección intraamniótica con transmisión vertical al neonato. La meningitis neonatal fue tratada con meropenem y el niño se dio de alta en buenas condiciones después de 41 días de hospitalización. Las guías perinatales actuales, preconizan el tamizaje de muestras vaginales para la prevención del parto prematuro y de los resultados adversos asociados a infección bacteriana ascendente durante el embarazo.

Metabolic stress and high intensity exercise

Received: February 14, 2017; Accepted: February 25, 2017; Published: February 28, 2017 Exercise-induced catecholamine responses are related to exercise intensity and are affected by the preceding training regimen. Although most investigations of catecholamine responses to training have utilized aerobic exercise models, it is likely that anaerobic training regimens will produce a considerably different physiological profile. Furthermore, depending on the acute resistance exercise variables (i.e., choice of exercise, order of exercise, rest intervals, load, volume of exercise), considerable physiological variation exists between different exercise protocols. To date, few studies have investigated catecholamine responses to an anaerobic overtraining models.
Study of placental weight in normal and pre-eclamptic pregnancies and its correlation with birth weight

Background: Placenta reflects the well being of the fetus and continuously undergoes a change in weight and function, to support the development of the fetus. The aim of this study was to assess and correlate the weight of placenta and fetal birth weight in normotensive and hypertensive pregnancies. Materials and Methods: Fifty placenta each of normotensive and pre-eclamptic pregnancies were studied (n=100). After delivery, weight of placenta and fetal weight was recorded using weighing machine. Results: In this study, 68.19% cases of low birth weight babies were found in pre-eclamptic group. Mean placental weight was 454.24 ± 47.52 grams and mean fetal weight was 2633.6 ± 302.2 grams in normal group. Whereas, in pre-eclamptic group, mean placental weight was 406.32 ± 59.33 grams and mean fetal weight was 2435.2 ± 280.56 grams. Mean placental and fetal weight were significantly lower in pre-eclamptic group, whereas, feto-placental weight ratio was significantly higher in pre-eclamptic group. A significant positive correlation was found between placental and fetal birth weight (r = 0.975, p<0.0001) in normal and (r = 0.971, p<0.0001) in pre-eclamptic group. Conclusion: Pre-eclamptic pregnancies significantly reduce placental weight. These changes may be due to placental insufficiencies as a result of compromised uteroplacental blood flow in pre-eclamptic pregnancies. The present study shows a strong positive correlation between placental and fetal weight. So, the knowledge of this correlation will be tremendously useful in the early assessment of placental insufficiencies and also the state of fetal well being.
A clinical case of intricate tracheal disease and asthma

Context : Asthma is the most common inflammatory disease of the airways in children. The term problematic asthma is used to describe children with chronic symptoms or acute severe exacerbations, or both, not responding to standard asthma therapy. Case Presentation : We describe the case of a 5 years old girl with a history of recurrent respiratory infections and asthma since the first months of life, with a poor response to conventional therapies (antibiotics, high dose corticosteroids combined with long-acting β2 agonists and oral leukotriene-receptor antagonists). In some cases she needed hospitalization for the important respiratory engagement and radiological findings of pulmonary consolidations, predominantly localized to the right lung. Computed tomography angiography (CTA), described a mild tracheobronchomalacia caused by the right innominate artery compression and a dense tissue mediastinal extrinsic compression of the main bronchus of the middle lobe, defined a Middle Lobe Syndrome (MLS). Evidence Acquisition : MLS is defined as a recurrent or chronic collapse or infection of the middle lobe of the right lung. There is often a history of multiple treatments with antibiotics and anti-asthmatic drugs for ‘‘recurrent pneumonia’’ or ‘‘asthma’’, as in our patient. Chest X-ray is the first-line diagnostic tool, especially on the lateral view. CT-scan and bronchoscopy are considered useful for diagnosis or treatment. Treatment depends on etiology of MLS. Conclusion : In case of severe asthma symptoms co-morbidities must be evaluated. MLS is frequently unrecognized in children and thinking of it is a prerequisite for diagnosis, especially when recurrent respiratory infections or asthma symptoms are predominantly localized to the right lung.
