Evolution of broad-line emission from active galactic nuclei

Apart from viewing-dependent obscuration, intrinsic broad-line emission from active galactic nuclei (AGN) follows an evolutionary sequence: type 1 → 1.2/1.5 → 1.8/1.9 → 2a s the accretion rate on to the central black hole is decreasing. This spectral evolution is controlled, at least in part, by the parameter Lbol/M 2/3 , where Lbol is the AGN bolometric luminosity and M is the black hole mass. Both this dependence and the double-peaked profiles that emerge along the sequence arise naturally in the disc-wind scenario for the AGN broad-line region.

Compact Planar Dual Band Antenna for WLAN Application

A miniaturized dual-band microstrip antenna has been designed and analyzed for Wireless LAN application. The proposed antenna comprises a 29 × 29 mm2 radiating patch, fed by a microstrip line on a 1.6 mm thick FR4 dielectric material substrate. The antenna measurement illustrates impedance bandwidth of around 10% at 2.4 GHz resonance and 6% at 5.5 GHz resonance. The measured stable return loss and radiation patterns are presented for the proposed dual-band electrically small microstrip antenna for wireless applications.
Propolis Effect on Rodent Models of Streptozotocin - Induced Diabetic Nephropathy

Diabetic nephropathy (DN) is a frequent complication in patients with long - standing type I diabetes mellitus (DM1 ) . The current study was aimed at identifying quantitatively and qualitatively renal histopathological abnormalities that occur with streptozotocin - induced diabetes in rats and their possible reversal after the establishment of good metabolic control with propolis. Fifty healthy adult male wistar rats were used, divided into 2 groups. Group I : (10 rats Control group) and Group II: (streptozotocin - induced diabetic rats), received a single intra - peri t oneal injection of 60mg/kg. Diabetes appea red after 1 - 3 days after STZ injection. The second experimental group was divided into 4 subgroups (10 rats each) . Group I I - a: Non - treated diabetic (positive control) rats, Group II - b: Diabetic rats treated daily with Humulin insulin 5 IU/ kg/day. Group II - c: Diabetic rats treated daily with same insulin dose + propolis 0.3 g/kg . Group II - d: treated similar to group IIc but with double dose of propolis 0.6 g/kg.

Hepatoprotective effects of glycine and vitamin E, during the early phase of liver regeneration in the rat

Our objective was to demonstrate the protective effect of glycine (Gly) and vitamin E (VE) on a model of ethanol-induced acute liver injury during the early phase of liver regeneration after partial hepatectomy (PH) in rats. Fifty male Wistar rats (body weight (b.w.), 240 280 g) were divided into four groups (n = 10, each, respectively) as follows: 1) control partial hepatectomy (PH), 70%; 2) PH + ethanol (EtOH) at 1.5 g/kg b.w; 3) PH + Gly (0.6 g/kg b.w) + EtOH, and; 4) PH + VE (400 International units [IU]) + EtOH. Twenty four h after surgery, animals were killed and liver damage and oxidative stress parameters were measured. Ethanol caused a decrease in serum albumin (2.27 vs 3.12 g/dL; p < 0.05), cholesterol (31.4 vs 48.0 mg/dL; p < 0.05), Aspartate aminotransferase (AST, 70 vs 380 UI; p < 0.05), and alanine aminotransferase (ALT, 110 vs 170 UI; p < 0.05) in comparison with the PH control group, but these decreases were reverted with either Gly or VE administration. Furthermore, Gly and VE administration decreased (p < 0.05) Thiobarbituric acid reactive (TBARS) levels, stimulated superoxide dismutase (SOD) activity, and a significant restitution of liver weight was observed. Our results suggested a protective effect against liver injury with glycine and VE supplementation. Treatment with either Gly or VE causes an elevation in total SOD activity and a decrease in TBARS levels, showing a protective effect in liver regeneration on a model of ethanol-induced acute liver injury after PH in rats.
The Emotion Pictured by a Dream : An Examination of Emotions Contextualized in Dreams

There are many different ways of examining dreams from both clinical and research perspectives. Research studies have generally focused on data that can be easily quantified, thus there are any number of studies using approaches such as Hall and van de Castle’s which involves counting total words or important words in dream reports, classifying settings, characters, actions, etc. (1). There are also many global rating scales that judge the entire dream report by degrees of dreamlikeness, bizarreness, vividness, amount of detail, etc. (2) Numerous interesting results have been produced by quantitative dream research using such scales, but often something has appeared to be missing. From the clinician’s point of view what is missing is the importance of the dream for the dreamer.

The Adoption of the Traffic Violation E-payment System ( TVEPS ) of Kuwait

E-government (e-gov) has become indispensable for government modernization. Its success, however, is contingent upon its adoption by the intended users. This research used an extended version of the Unified Theory of Acceptance and Use of Technology (UTAUT) model to investigate a number of factors that are believed to affect the Kuwaiti citizens’ adoption of the traffic violation e-payment system (TVEPS). Effort expectancy and social influence were found to influence the use intention, and users’ Internet experience moderated such a relationship. However, performance expectancy did not influence the intention to use TVEPS. Facilitating condition, trust and use intention were found to influence the actual use of the system. While gender moderated the relationship between facilitating conditions and actual use of the system, awareness moderated the relationship of trust and use intention with the actual use of the system. These findings and their implications are further discussed in the paper.
Impact of Lactobacillus paracasei HD1.7 as a Starter Culture on Characteristics of Fermented Chinese Cabbage (Brassica rapa var. pekinensis)

Lactobacillus paracasei HD1.7, an isolate from Chinese fermented cabbage and producer of bacteriocin, was used as a starter culture to estimate the impact on characteristics of fermented cabbage. The results of quantitative real-time PCR showed that in Lb.paracasei HD1.7 fermented sample, the total bacteria number was significantly higher during the initial and medium stages. Lb.paracasei HD1.7 significantly increased the final concentration of lactate (7.13 g/L), mannitol (19.41 g/L) and seven amino acids while kept vitamin C more stable (43.20 mg/kg). Meanwhile, nitrite was lower than 0.16 mg/kg throughout the whole fermentation process. The fermented cabbage with Lb.paracasei HD1.7 was more favorable by consumers in terms of crisp, sourness, aroma, bitterness, stink, stale flavor and overall acceptability. Lb.paracasei HD1.7 fermented cabbage had more nutritive values and healthpromoting effects. This suggested Lb.paracasei HD1.7 a practical potential in industrially production as a starter culture of fermented cabbage and other fresh vegetables.
Effect of Chemical and Organic Fertilizers on Yield and Essential Oil of Chamomile Flower Heads

Two experiments were carried out under sandy soil conditions at the experimental station of Sekem Company, Sharkiya region, Egypt during two successive seasons of 2008/2009 and 2009/2010 to study the productivity of chamomile (Matricaria chamomilla L.) flower heads as influenced by different chemical fertilizers, compost rates and liquid compost. All compost + liquid compost treatments overcame the chemical fertilizers or compost treatments and improved the flower heads growth characters [i.e. fresh or dry weights of flower heads (g plant) and flower head diameter (cm)] and essential oil contents [% and g plant]. For various essential oil constituents increased, decreased, or did not change in M. chamomilla L. flower heads under chemical and organic fertilizers as compared with unfertilized control plants. _____________________________________________________________________________________________________________
Stem Cell Therapy for Traumatic Brain Injury: A Progress Update

Traumatic Brain Injury (TBI) is an unpleasent accident frequently encounted in daily life. Strong force suddenly destructs brain tissue and vascular struction that result in immediate tissue contusion, cellular edema and hemorrhage. The intracranial pressure is rapidly elevated, blood flow is simultaneously decreased. These events initiate various subsequent responses and amplify the severity of primary brain damage. Injured neurons, axons and tracts fail to conduct normal activity and eventually lead to a high rate of disability. Currently there is no effective pharmacological agents to completely rescue the damaged brain tissue. Stem cells have the ability of self-renew and produce differented tissues that are proposed to rebuild this impaired biological structure. In response to traumatic injury, endogenous neural stem cells in the subventricular zone and dentate gyrus are activated to produce neurogenesis and angiogenesis [1,2]. Animal studies have demonstrated that these cells are proliferated and migrate toward to the injury site. They are able to differentiate into neurons and glia and integrate with the local cells. Unfortunately, the number of new generated cells is not sufficient to reach the urgent need of the body. Transplantation is the efficient way to deliver stem cells into the injury site and solve this shortage. Preclincial animal studies were done in several disease models with different types of stem cells [3]. Clinical trials have been performed in stroke [4,5], spinal cord injury [6-8], neurodegenerative diseases [9] and other diseases [10-13]. Both preclinical and clinical trials indicate that stem cell transplantation has the potential to be used for treating patients.
Gestural coordination of Italian word-initial clusters: the case of ‘impure s’*

We report on an articulatory study which uses an electromagnetic articulograph to investigate word-initial consonant clusters in Italian. In particular, we investigate clusters involving a sibilant, such as in spina ‘thorn’. The status of the sibilant in such clusters, referred to as ‘impure s’, is an unresolved problem for the syllable phonology of Italian. Coordination patterns of the gestural targets of consonantal and vocalic gestures reveal a structural difference between obstruent–liquid clusters, e.g. /pr/, and sibilant–obstruent clusters, e.g. /sp/. Whereas in /pr/, both /p/ and /r/ have distinct coordination patterns as compared to either /p/ or /r/ as a single consonant in the same (word-initial) position, this is not the case for /sp/. Here the /p/ patterns like a single consonant: /p/ in spina patterns with /p/ in Pina (proper name). Thus, although /s/ in spina constitutes a word onset, there is evidence against it being part of a syllable onset.
Effect of Additive Tamoxifen Citrate to SMART Medium on Human Sperm Parameters during In vitro Sperm Activation

This study was aimed to investigate the effect of addition of tamoxifen citrate on the outcome of in vitro human sperm activation. One hundred semen samples for fertile and infertile men were randomly collected from the subjects at the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies / AlNahrain University. The mean age was (32.21± 0.83) years and mean duration of infertility was (5.26 ± 0.41) years. Before using centrifugation swim-up technique, the washed samples were divided into three groups: control group (G1) without tamoxifen citrate, while in the second(G2) and third(G3) group, two concentrations oftamoxifen citrate (20μg/mL and 40μg/mL) respectively were added post-activation enriched with SMART medium. Macroscopic examination of semen included: Semen liquefaction time, semen pH, semen viscosity and semen volume, while microscopic examination of semen included: sperm concentration, motility, morphology, agglutination and cells other than spermatozoa. The results showed significant (P<0.05) increased in sperm motility, progressive sperm motility and normal sperm morphology of post-activation as compared with preactivation. Among treated groups, a significant (P<0.05) decreased was found in sperm concentration, immotile sperm and total progressive sperm, while a significant (P<0.05) increased was observed in progressive sperm motility and normal sperm morphology in (G3) as compared with others groups. Based on the results of this study, it can be concluded that the addition of 40μg/mL of tamoxifen citrate to washed sperms can improve sperm motility.
Within-pair similarity in migration route and female winter foraging effort predict pair breeding performance in a monogamous seabird

In long-lived monogamous animals, pair bond strength and durability are usually associated with higher fitness. However, whether pairs maximise fitness during the non-breeding season by maintaining contact during the winter or, instead, prioritise individual condition is unclear. Using geolocators recording spatial (light) and behavioural (immersion) data, we tracked pairs of the long-term monogamous Atlantic puffin Fratercula arctica during the non-breeding season to determine whether and how migratory strategies were related to future pair breeding performance and whether within-pair similarity in migratory movements or individual behaviour best predicted future fitness. While pair members migrated separately, their routes were similar in the first part of the non-breeding season but diverged later on; nonetheless, pairs showed synchrony in their return to the breeding colony in spring. Pairs following more similar routes bred earlier and had a higher breeding success the following spring. However, female (but not male) winter foraging effort was also a strong predictor of subsequent fitness, being associated with future timing of breeding and reproductive success. Overall, females had higher daily energy expenditure than males, especially in the late winter when their route diverged from their partner's and they foraged more than males. Our study reveals that female winter foraging, probably linked to pre-breeding condition, may be more critical for fitness than maintaining the pair bond outside of the breeding season. However, even without contact between mates, pairs can benefit from following similar migration routes and synchronise their returns, but the mechanisms linking these processes remain unclear.
Learning to Read and Spell English Words by Chinese Students

This study examined the structural relationships between (a) the latent independent constructs of orthographic and lexical knowledge and phonological sensitivity and (b) the effect of these constructs on the latent construct of literacy manifested by reading aloud and spelling regular and exception English words in 156 Cantonese-speaking Chinese students (M age = 10.8 years) who were learning English as a second language in Hong Kong. Three carefully designed and item-analyzed indicators subserved the construct of orthographic and lexical knowledge, and another three indicators subserved the construct of phonological sensitivity. Our hypothesis of greater contribution of word-specific orthographic and lexical knowledge than phonological sensitivity to learning to read and spell English words in these Chinese children was supported by results from multiple regression, principal component analyses and especially by structural equation modeling. The various goodness-of-fit dexes showed the appropriateness of the indicators in measuring the latent constructs as well as the relationships among these constructs.
Magnetism of "Zn,Co…O thin films probed by x-ray absorption spectroscopies

We report on the electronic and magnetic properties of Co-doped ZnO thin films investigated by x-ray absorption spectroscopies and element selective magnetometry. For a low Co concentration (around 5%), we evidence a paramagnetic phase clearly correlated to Co2+ ions substituted to Zn in the ZnO matrix. For higher Co concentrations (around 25%), we demonstrate the coexistence of both paramagnetic and ferromagnetic phases. The use of advanced element and orbital selective techniques allows us through the distinct spectral signature of Co in ionic or metallic states to assign the ferromagnetic phase to the presence of Co in a metallic state as a consequence of Co metal clustering in our films.
GPS scintillation effects associated with polar cap patches and substorm auroral activity: direct comparison

We directly compare the relative GPS scintillation levels associated with regions of enhanced plasma irregularities called auroral arcs, polar cap patches, and auroral blobs that frequently occur in the polar ionosphere. On January 13, 2013 from Ny-Alesund, several polar cap patches were observed to exit the polar cap into the auroral oval, and were then termed auroral blobs. This gave us an unprecedented opportunity to compare the relative scintillation levels associated with these three phenomena. The blobs were associated with the strongest phase scintillation (σ ϕ ), followed by patches and arcs, with σ ϕ up to 0.6, 0.5, and 0.1 rad, respectively. Our observations indicate that most patches in the nightside polar cap have produced significant scintillations, but not all of them. Since the blobs are formed after patches merged into auroral regions, in space weather predictions of GPS scintillations, it will be important to enable predictions of patches exiting the polar cap.
Solid lipid nanoparticles of stearic acid for the drug delivery of paliperidone

Paliperidone is an antipsychotic drug having poor water solubility and bioavailability. Solid lipid nanoparticles of stearic acid loaded with paliperidone were prepared to enhance the bioavailability. Spherical nanoparticles of stearic acid containing paliperidone were prepared with a surfactant, biz. Gelucire® 50/13 forming a stabilizing layer over the nanoparticles. The particle size of the SLNs was found to exponentially decrease with the increase in surfactant concentration. Dynamic light scattering (DLS), transmission electron microscopy (TEM) and atomic force microscopy (AFM) imaging revealed that the average particle size of SLNs was 230 ± 30 nm. Fourier transform infra-red spectroscopy (FTIR), X-ray diffraction (XRD) and differential scanning calorimetry (DSC) analysis revealed that there was no chemical interaction between the ingredients of the SLNs. However, molecular dispersion of the paliperidone in the stearic acid matrix led to a reduction in the crystallinity of stearic acid. The entrapment efficiency of paliperidone in the lipid was calculated as 42.4 (% w/w). The corresponding % drug loading was calculated as 4.1 (% w/w) of the total lipid content. A controlled release pattern was observed in the in vitro release kinetics studies. In vitro cell culture studies against RAW 264.7 murine macrophages revealed that the paliperidone loaded SLNs have some cytotoxicity. But the observed toxicity was not concentration dependent as there was at least 60% viability of the cells in the concentration range of 30–120 μg ml−1.
The Relationship between Firearm Ownership and Violent Crime

Criminologists and other researchers have attempted to understand whether there is a connection between firearm prevalence and crime. Some experts have argued that prevalence of firearms increases crime, while others have argued it reduces crime. The purpose of this study was to further investigate and clarify this relationship. The current analysis used suicide by firearm as a proxy for firearm ownership. Examining violent crime, homicide, rape, robbery, and assault for 1,997 counties in the United States, the findings indicate that increased prevalence of firearms was associated with increased violent crime, homicide, rape, robbery, and assault. The results of this study suggest that a decrease in prevalence of firearms has the potential to decrease violent crime in the United States. 1 Grand View University 2 Iowa State University Corresponding Author: mmoore@grandview.edu
