Cardiac dysfunction in cirrhotic portal hypertension with or without ascites Sunil Dadhich a
No full textAbstract Background Alteration of cardiovascular functions in patients with liver cirrhosis has been described and it correlates with severity of hepatic failure. But cardiac functions by conventional 2-dimensional (2-D) echocardiography has limitations. Th e aim of the study was to evaluate cardiac systolic and diastolic functions in liver cirrhosis patients with or without ascites by tissue Doppler imaging and conventional 2-D-echocardiography
1-6Improved Optical Properties of Tin Antimony Sulphide Thin Films for Photovoltaics
No full textAbstract Tin antimony sulphide thin films have been synthesized as an absorber layer for solar cells. These films are deposited by vacuum thermal evaporation on glass substrate at a pressure of 10 -5 torr. The films are then annealed at different temperatures in argon atmosphere. XRD analysis reveals that both as deposited and annealed films are found to be in polycrystalline phase. The crystallinity of the films is significantly enhanced with increasing annealing temperatures. The quantum efficiency is higher in the visible and near infrared region for the annealed films whereas the quantum efficiency of as deposited film is comparatively lower. The transmittance of the annealed films is found to be decreasing with increasing temperatures. The thickness and band gap of the films are measured by ellipsometric data. The absorption coefficient of the films is significantly higher (~10 5 cm -1 ), which is very important factor regarding solar conversion efficiency. Hot point probe measurements show that the films possess ntype electrical conductivity

Hippocampal-prefrontal circuit and disrupted functional activity in psychiatric and neurodegenerative disorders. Biomed Res. Intern. Volume 2015 article ID 810548
No full textIn rodents, the hippocampus has been studied extensively as part of a brain system responsible for learning and memory, and the prefrontal cortex (PFC) participates in numerous cognitive functions including working memory, flexibility, decision making, and rewarding learning. The neuronal projections from the hippocampus, either directly or indirectly, to the PFC, referred to as the hippocampal-prefrontal cortex (Hip-PFC) circuit, play a critical role in cognitive and emotional regulation and memory consolidation. Although in certain psychiatric and neurodegenerative diseases, structural connectivity viewed by imaging techniques has been consistently found to be associated with clinical phenotype and disease severity, the focus has moved towards the investigation of connectivity correlates of molecular pathology and coupling of oscillation. Moreover, functional and structural connectivity measures have been emerging as potential intermediate biomarkers for neuronal disorders. In this review, we summarize progress on the anatomic, molecular, and electrophysiological characters of the Hip-PFC circuit in cognition and emotion processes with an emphasis on oscillation and functional connectivity, revealing a disrupted Hip-PFC connectivity and electrical activity in psychiatric and neurodegenerative disorders as a promising candidate of neural marker for neuronal disorders
A POLYNOMIAL CHARACTERIZATION OF CONGRUENCE CLASSES
No full textAbstract Let V be a regular and permutable variety and A = (A, F ) ∈ V. Let ∅ = C ⊆ A. We get an explicite list L of polynomials such that C is a congruence class of some θ ∈ Con A iff C is closed under all terms of L. Morevover, if V is of a finite similarity type, L is finite. If also A ∈ V is finite, all polynomials of L can be considered to be unary. We get a formula for the estimation of card L. The problem of deciding whether C is a congruence class is a finite algebra is in N P but for A ∈ V it is in P . Mathematics Subject Classification: 08A30, 08A40, 08B05, 68Q25 Let A = (A, F ) be an algebra, let ∅ = C ⊆ A. It was proved by A. I. Mal 'cev [5] that C is a class of some θ ∈ Con A if and only if either τ (C) ∩ C = ∅ or τ (C) ⊆ C for any translation of A. Let us recall that by a translation is in [5] meant a unary polynomial. Although this characterization is simple and very useful thourough general algebra, its disadvantage is that an algebra A = (A, F ) can have an infinite number of unary polynomials even if A or F are finite. We are going to give another polynomial characterization of congruence classes for algebras of regular and permutable varieties where for F finite we need only a finite set of testing polynomials. Recall that an algebra A = (A, F ) is regular if θ = Φ for θ, Φ ∈ Con A whenever they have a congruence class in common. A is permutable if θ • Φ = Φ • θ for every θ, Φ ∈ Con A. A variety V is regular or permutable if each A ∈ V has this property. The following Mal'cev type characterization was derived independently i
Effects of Context on Time-Compressed Speech Intelligibili& in Older Adults
No full textAbstract: Recent studies have shown conflicting results on speech intelligibility tests using high rates of speech (timecompressed) for older listeners. Possible explanations are differences in context as well m in time-compression algorithms. The purpose of this study was to compare the speech understanding of older listeners on the R-SP~low predictability sentences with the high context CST sentences at three different rates of speech using one single time-compression algorithm, BACKGROUN
The neurotoxicity and safety of treatment with cefepime in patients with renal failure. Nephrol Dial Transplant 2008
No full textAbstract Background: Cases of cefepime neurotoxicity have been Sporadically reported in patients with renal failure. The neurotoxicity of cefepime might be underestimated and the frequency of its neurotoxic effects may be insufficiently recognized. Methods: We retrospectively reviewed the files of patients with renal failure who were treated with cefepime and who developed neurological complications. Results: All 8 patients developed decreased conscience, confusion, agitation, global aphasia, myoclonus, choreaathetosis, convulsions and coma. The latency, the period between the start of treatment and neurologicaldeterioration, was 4,75 ± 2,55 days (range: 1-10 days). All patients died 17 ± 14,7 days (range: 1-42 days) after becoming symptomatic. Three of them died shortly after neurological deterioration. Five patients developed a neurological "tableau" with global aphasia. Three patients showed clinical improvement after the discontinuation of cefepime. Electroencephalography revealed diffuse slow-wave activity (delta) and triphasic sharp wave activity. These findings confirm the possible neurotoxicity of treatment with cefepime in patients with renal failure. In none of the deceased patients have we been able to directly demonstrate a causal relationship between neurotoxicity and mortality. However, when a patient treated with cefepime develops neurological deterioration or aphasia, one must be aware of cefepime's potential neurotoxicity and treatment should be stopped. Conclusion: We recommend that, in view of the high and unexplained mortality, the use of cefepime in patients with kidney failure should be carefully considered
No full textAbstract Violence against women is a global problem of great magnitude. After laying out some sample data on violence against women, I argue that this violence, and its ongoing threat, interferes with every major capability in a woman's life. Next, I argue that it is the capabilities approach we need, if we are to describe the damage done by such violence in the most perspicuous way and make the most helpful recommendations for dealing with it. But the capabilities approach will be helpful in this area only if it develops effective arguments against cultural relativism and in favor of a context-sensitive universalism, and only if it is willing to make some claims, albeit humble and revisable, about which capabilities are most deserving of state protection, as fundamental entitlements of all citizens. Finally, I sketch some possible implications of the capability approach for public policy in this area. Key words: Women, Violence, Capabilities, Universalism, Relativism Violence and the threat of violence No woman in the world is secure against violence. Throughout the world, women's bodies are vulnerable to a range of violent assaults that include domestic violence, rape within marriage, rape by acquaintances or dates, rape by strangers, rape in wars and communal conflicts, honor killing, trafficking and forced prostitution, child sexual abuse, female infanticide, female genital mutilation, and sex-selective abortion. Other practices that are not as obviously violent also contribute to the atmosphere of threat in which all women live the entirety of their lives: sexual harassment, stalking, threats of violence, deprivation of bodily liberty, the undernutrition of girls. The United Nations Declaration on the Elimination of Violence against Women (1994) defines violence against women as ''any act of gender-based violence that results in, or is likely to result in, physical, sexual or psychological harm or suffering to women, including threats of such acts, coercion or arbitrary deprivation of liberty, whethe
Obligations and Rights of Licensor and Licensee in a Patent Licence Obligations and Rights of Licensor and Licensee in a Patent Licence
No full textAbstract This paper discusses one of the different aspects of licensing agreement to exploit patented technology. Such licensing agreements are important when considering technology transfers to developing countries. The study addresses whether the current Libyan legal framework are able to accommodate such licences in terms of identifying the right and obligations of the parties. Of course, the license agreement is the main source of these obligations based on the rule of a contract makes the law among parties. Thus, the patent holder is expected to take all necessary actions to convey the patentable invention and allow the licensee to manufacture the licensed technology. The licensee, on the other hand, is expected to pay royalties and exploit the licensed technology. The parties must agree on terms and conditions to rule such agreements because of the absence of special regulations governing such agreements
