Study the Some Semen Parameters of Fertile and Infertile Male in Misan Province

Background : Infertility in human is described as a situation in which a couple (male and female) does not succeed in achieving pregnancy despite of unprotected sexual intercourse over a period of 12 months. The aim of the current study was to collect and analyses quantitative baseline data about the males suffering from the impaired infertility in Misan province. Material and Methods : semen samples have been collected and examined for 60 married male suffering from impaired fertility group and 19 health's married male as a control. Results : In regards to the mean volumes of seminal fluid and the pH values, the results showed that there were no statistically significant difference between infertile and control group. However, the results revealed the differences between the control and the infertile groups were highly significant for the total sperm count (p < 0.01). In terms of the percentage of normal and abnormal sperm morphology, were no significant differences between the control and the infertile groups. The percentage of active sperm motile was significant (p< 0.05) in the control group compared with the infertile group. While the percentage of non motile sperm was significant (p< 0.05) in non fertile males in comparison to the males in the control group. Differences between the control and the infertile groups were non-significant regarding the percentage of weakness and sluggish sperm. The varicocele was the higher percentage while hormonal disorder was the lower percentage than the other causes. The incidence of infertility was more common among men in urban population compared with infertile men in rural population with a significant difference of (p < 0.01).

NUMERICAL AND EXPERIMENTAL INVESTIGATION INTO THE EFFECTS OF VISCOSITY AND INJECTION RATE ON RELATIVE PERMEABILITY AND OIL RECOVERY

Relative permeability is one of the most basic, yet problematic, parameters used in reservoir engineering and is extremely important for predicting oil recovery. Traditionally, water-oil relative permeabilities are determined in the laboratory for a given injection rate and viscosity ratio, usually higher than those encountered in the reservoir. Then simulation studies are carried out for a different (usually lower) rate and viscosity ratio using the same relative permeability curves. The validity of this approach, to our knowledge, has not yet been fully investigated. In this paper we report the results from a series of well-characterised unsteady state water floods in bead-packs and detailed simulations performed on the same system. The aim of this study was: • to investigate the effect of oil-water viscosity ratio on relative permeability and oil recovery curves • to investigate the effect of water injection rate on relative permeability and oil recovery curves The use of bead-packs rather than cores enabled us to control the homogeneity and wettability of the porous medium and to visually observe the fluid flow patterns during each experiment. Displacements were performed at two viscosity ratios and three different injection rates and the relative permeabilities were determined using the JBN unsteady-state method. It was observed that the shape of the JBN derived relative permeabilities changed significantly with both viscosity ratio and rate. This was despite the fact that the interfacial tension and contact angle were very similar for all displacements. All measured experimental data (permeability, porosity, rate, viscosity ratio and relative permeability) were then input into a simulator in order to evaluate the possible errors that might arise in field scale simulation from using relative permeabilities determined at one rate and viscosity ratio to predict waterflood performance for a different rate and viscosity ratio. Our results indicate that, at least for the fluid system
Developing Trainee Translators’ Strategic Subcompetence Through Metacognitive Questionnaires

This paper presents a case study carried out in a two-part German-Spanish general translation course. It results from a pedagogical intervention aimed at helping first-year translation students to develop their strategic subcompetence through metacognitive questionnaires. It focuses on a single function of this subcompetence, the evaluation of trainees’ translating, which was carried out by using post-translation metacognitive questionnaires. These were meant for trainees to reflect on certain aspects of their translating. The most relevant ones were the identification of translation problems and the justification of their solutions. Both aspects were addressed by a twofold question aimed at helping students to identify adequately-solved problems and to justify their solutions. An analysis of students’ answers to this question reveals that the most frequently identified items were strategically relevant problems to do with general conventions of style and genre-specific expressions. Solutions to these problems were also the most frequently justified, and references to successfully applied translation strategies increased from one part of the course to the other as a trace of gradually developing strategic subcompetence.
Fathers and the Responsibility for Children: A Puzzle and a Tension

Drawing on a qualitative study of Canadian fathers who self-define as primary caregivers, this paper explores men's unique challenges to the gendered politics of unpaid work. While recognizing that fathers' narratives can widen our understandings of what it means to care for and take on the emotional responsibility for children, I also draw attention to the political and theoretical tensions that sit on the edges of feminist research on fathering.
DETECTION OF HIGH-FREQUENCY EEG ACTIVITY IN EPILEPTIC PATIENTS

This work deals with automated detection of high-frequency oscillations as a novel electrophysiologic biomarker of epileptogenic tissue in intracranial EEG. Visual detection of these oscillations is a timeconsuming process and is prone to reviewer bias. Epilepsy is one of the most common neurological diseases affecting 1% of population. Even though two thirds of cases are successfully treated with anti-epileptic drugs, the rest of the patients are dependent mainly on surgical procedure, which requires precise localization of pathologic focus. High-frequency oscillations have been studied over the last decade for their potential to localize the focus of pathological tissue. Initial part of this work is a summary of the current state of high-frequency oscillations research and a detailed list of detectors used in research. Within the scope of this work three high-frequency oscillation detectors were developed or enhanced. The description of the algorithms is followed by detector evaluation with regard to the concordance with expert reviewed events, feature estimation and the ability to correctly localize pathological tissue. The final part of the work provides an overview of developed visualization methods and a short summary of achieved scientific results.

Exploring the Frontier of Livelihoods Research

This article discusses the value of livelihoods studies and examines the obstacles which have prevented it from making a greater contribution to understanding the lives of poor people over the past decade. After examining the roots of the livelihoods approach, two major challenges are explored: the conceptualization of the problem of access, and how to achieve a better understanding of the mutual link between livelihood opportunities and decision-making. The article concludes that access to livelihood opportunities is governed by social relations, institutions and organizations, and that power is an important (and sometimes overlooked) explanatory variable. In discussing the issue of access to livelihood opportunities, the authors note the occurrence of both strategic and unintentional behaviour and the importance of structural factors; they discuss concepts of styles and pathways, which try to cater for structural components and regularities; and they propose livelihood trajectories as an appropriate methodology for examining these issues. In this way, the article also sets the agenda for future livelihoods research.
Recent advances and application of PD-1 blockade in sarcoma

Abstract The role of the programmed death-1 (PD-1) signaling pathway in tumor immunotherapy is becoming increasingly important, and several PD-1-blocking agents have been approved by the US Food and Drug Administration. PD-1-blocking therapy alone or in combination with other therapeutic modalities has become a standard treatment for several kinds of solid tumors. However, sarcomas are not indications for anti-PD-1 therapy. Sarcomas are a group of heterogeneous diseases that can currently only be cured by surgery at the early stage. No effective treatments exist for sarcoma patients in advanced stages. Owning to the diversity of sarcomas, it is very difficult to conduct randomized controlled clinical studies on specific subtypes of sarcomas. Although clinical studies of sarcomas continue, few breakthroughs in the treatment of sarcomas have been achieved over the past decades. This review summarizes recent progress in anti-PD-1 therapy for sarcomas. Based on the published data, PD-1 blockade may be more effective in combination with other modalities for the treatment of sarcomas. In addition, biomarkers may be used to ascertain sensitivity to PD-1 blockade in sarcoma patients.
Influences of aspect ratio and wall boundary condition on laminar Rayleigh–Bénard convection of Bingham fluids in rectangular enclosures

Purpose This paper aims to investigate the aspect ratio (AR; ratio of enclosure height:length) dependence of steady-state Rayleigh–Benard convection of Bingham fluids within rectangular enclosures for both constant wall temperature and constant wall heat flux boundary conditions. A nominal Rayleigh number range 103 ≤ Ra ≤ 105 (Ra defined based on the height) for a single representative value of nominal Prandtl number (i.e. Pr = 500) has been considered for 1/4 ≤ AR ≤ 4. Design/methodology/approach The bi-viscosity Bingham model is used to mimic Bingham fluids for Rayleigh–Benard convection of Bingham fluids in rectangular enclosures. The conservation equations of mass, momentum and energy have been solved in a coupled manner using the finite volume method where a second-order central differencing scheme is used for the diffusive terms and a second-order up-wind scheme is used for the convective terms. The well-known semi-implicit method for pressure-linked equations algorithm is used for the coupling of the pressure and velocity. Findings It has been found that buoyancy-driven flow strengthens with increasing nominal Rayleigh number Ra, but the convective transport weakens with increasing Bingham number Bn, because of additional flow resistance arising from yield stress in Bingham fluids. The relative contribution of thermal conduction (advection) to the total thermal transport strengthens (diminishes) with increasing AR for a given set of values of Ra and Pr for both Newtonian and Bingham fluids for both boundary conditions, and the thermal transport takes place purely because of conduction for tall enclosures. Originality/value Correlations for the mean Nusselt number Nu¯ have been proposed for both boundary conditions for both Newtonian and Bingham fluids using scaling arguments, and the correlations have been demonstrated to predict Nu¯ obtained from simulation data for 1/4 ≤ AR ≤ 4, 103 ≤ Ra ≤ 105 and Pr = 500.
Seed germination in the Great Basin halophyte Salsola iberica

Salsola iberica Sennen & Pau, a halophytic forb in the family Chenopodiaceae, is widely distributed in in- land salt deserts of Utah and widespread in North America. Experiments were conducted to determine the effects of NaCl and temperature on seed germination and their recovery of germination from saline conditions after being trans- ferred to distilled water. Seeds of S. iberica were germinated at various temperatures and at various salinities in a 12 h light : 12 h dark photoperiod to determine their germinability under these conditions. Increases in NaCl concentration progressively inhibited seed germination. Few seeds germinated at 1000 mM NaCl. Cooler temperatures significantly inhibited germination, while high night (25°C) and high day (35°C) temperature regimes showed higher germination. Rate of germination decreased with an increase in salinity. Germination rate was higher at 25-35°C and lower at 5- 15°C temperatures. Seeds were transferred from salt solutions to distilled water after 20 days, and those from low salinities recovered quickly at cooler temperature regimes. Recovery germination percentages substantially decreased with an increase in salinity and temperature.
Effect of tillage and use of organic and inorganic fertilizers on growth and yield components of maize.

Tillage is an important crop production practice which affects crop performance. It was laid out in randomized complete block design (RCBD) with three replications. An experiment was conducted during the spring and autumn crop seasons 2009-2010.The objective of the trial was to compare the effect of three different tillage regimes namely, deep tillage, conventional tillage and zero tillage, and four fertilizer levels. Results showed that plant height, 1000-grain weight, grain yield and dry matter were maximum with deep tillage as compared to conventional and zero tillage. Comparing the seasons, the overall better plant height, 1000grain weight, grain yield and dry matter were gained during autumn season due to its crop residue effect and supplemental fertilizer. Therefore, considering the environmental conditions, the deep tillage with recommended dose of organic and inorganic fertilizer performed best and provided more vegetative growth, grain yield and dry matter in maize. Residual effects and supplemental fertilizer application in maize production were greater than fresh maize production.
Is discretionary fiscal policy a mitigating mechanism that counteracts business cycle fluctuations in the European Monetary Union

The aim of the thesis is to evaluate the reaction in fiscal stance in EMU with the purpose to investigate if there is a need for discretionary fiscal policy as a stabilizing mechanism due to the existence of country-specific disparities in order to counteract business cycle fluctuations in the Monetary Union. The second objective is to analyse the role of discretionary fiscal policy during three downturns. The data range from 1992 to 2009 and consist of yearly time series. A Two-Stage Least Square model was used to calculate the reaction in cyclically ad-justed primary government balance to the variation in output gap, government debt, mone-tary gap, election year and at last to the government behaviour in response to booms and busts. Statistically significant results from both country-specific and panel data show that discretionary fiscal policy has been countercyclical since 1992 and throughout the period. From the evaluation of discretionary fiscal policy behaviour during the three downturns it is clear that the general fiscal behaviour was more procyclical for the estimation groups during the first downturn as opposed to the latest two.

Macroeconomic Uncertainty , Difference in Beliefs , and Bond Risk Premia

In this paper we study empirically the implications of macroeconomic disagreement for bond market dynamics. If there is a source of heterogeneity in the belief structure of the economy then differences in beliefs can affect equilibrium asset prices. Using survey data on a unique data set we propose a new empirically observable proxy to measure macroeconomic disagreement and find a number of novel results. First, consistent with a general equilibrium model, heterogeneity in beliefs affect the price of risk so that belief dispersion regarding the real economy, inflation, short and long term interest rates predict excess bond returns with R 2 between 21%43%. Second, macroeconomic disagreement explains the volatility of stock and bonds with high statistical significance with an R ∼ 26% in monthly projections. Third, disagreement also contains significant information trading activity: dispersion in beliefs explains the growth rate of open interest on 10 year treasury notes with R equal to 21%. Fourth, while around half the information contained in the cross-section of expectations is spanned by the yield curve, there remains large unspanned component important for bond pricing. Finally, we control for an array of alternative predictor variables and show that the information contained in the belief structure of the economy is different from either consensus views or fundamentals.

Helping Patients with Mental Illness Engage in Their Transitional Care

Background: As many as 40% of individuals with behavioral health challenges (BHCs) that require hospitalization—such as psychotic disorders, affective disorders, and severe anxiety disorders—do not attend any outpatient visits in the 30 days following discharge. 1 Objectives: We examined engagement focused care (EFC) versus treatment as usual (TAU) in a university-based transitional care clinic (TCC) with a 90-day program serving individuals with BHCs who were discharged from hospitals and emergency departments (EDs). EFC included a unique group intake process, designed to get individuals into care rapidly, and a coach for shared decision making (SDM). Methods: We approached individuals for study either before hospital discharge or upon arrival to the TCC, following referral. Assessments of quality of life, symptomatology, and SDM preferences were conducted at an initial assessment, at 3 months (corresponding to the end of TCC treatment), and 6 months post-TCC discharge. We assessed communication among participants and providers at each TCC visit and we assessed service utilization during and post-TCC for inpatient, outpatient, emergency, and hospital services as well as in criminal justice contexts. Results: For the primary outcome—ie, subjective quality of life from the Quality of Life Interview—465 patients were randomized, 326 completed an initial assessment, 274 were lost to follow-up (139 of these never even received an initial assessment), and 191 had an initial and at least 1 follow-up assessment and were included in the primary repeated measures analysis of covariance for mixed models. Mean subjective quality of life scores were 3.88 (CI 95%, 3.73-4.02) and 3.78 (CI 95%, 3.56-4.00) for EFC and TAU, respectively, at initial assessment; 4.33 (CI 95%, 4.14-4.52) and 4.04 (CI 95%, 3.78-4.29) at 3 months; and 4.48 (CI 95%, 4.26-4.70) and 4.19 (CI 95%, 3.93-4.45) at 6 months. The mixed effects regression, examining impact on subjective quality of life, yielded significant effects of group (ie, EFC vs TAU) at 3 months (F1,216 =
GENETIC VARIABILITY AND CORRELATION STUDIES IN BIRD OF PARADISE GENOTYPES FOR FLOWER AND YIELD PARAMETERS DURING 2011

Experiment was conducted to study the genetic variability and association among the yield component traits in Bird of paradise. All the genotypes showed considerable amount of variation in their mean performances with respect to the characters studied, indicates presence of sufficient variability and scope for further selection and breeding superior and desirable genotypes. Large differences between GCV and PCV were observed in flower stalk girth (19.73 and 23.15%), vase life (19.92 and 21.71%) and number of bracts (39.04 and 42.64%), indicating the role of environment in expression of these traits. The magnitude of variability parameters were all high for suckers/hill (2.80 and 3.44) compared to flowers/hill (0.57 and 1.07), indicating wide variability for suckers/hill. All flowering characters exhibited high heritability coupled with high genetic advance over per cent mean indicating the predominance of additive components. Thus direct selection helps in improving the characters. Number of flowers per hill showed positive and significant correlations with plant height (0.478 and 0.293), stem girth (0.283 and 0.172), leaf width (0.204 and 0.162), leaf length (0.568 and 0.291), number of leaves per plant (0.640 and 0.275) and number of suckers per hill (0.766 and 0.976) at genotypic and phenotypic levels. Among the genotypes studied, number of suckers exhibited significantly high positive association with number of flowers. Thus, suggesting the possibility of simultaneous selection for this character.
Detection and phenotypic characterization of methicillin-resistant Staphylococcus aureus from clinical and community samples in Abakaliki, Ebonyi State, Nigeria

Objective The objective of this study was to isolate and phenotypically characterize methicillin-resistant Staphylococcus aureus (MRSA)from clinical and community samples in Abakaliki, Nigeria. Methods A total of 709 clinical (303) and community samples (406) samples were obtained for this study. MRSA isolates were detected using Kirby-Bauer disc diffusion method with the inclusion of 1 µg oxacillin and cefoxitin antibiotic disc. The isolates were screened for the β-lactamase production using nitrocefin sticks. Results A total of 44 MRSA isolates were obtained from the samples with prevalence frequency of 22.6 % and 20.8 % from clinical and community samples respectively. The clinical isolates were completely resistant (100 %) to ceftazidime, tetracycline and penicillin. Gentamicin and ciprofloxacin were the most effective antibiotics against the clinical and community isolates respectively with a susceptibility frequency of 63.2 % and 80 %. Exactly 38.1 % and 24.2 % of the clinical and community S. aureus isolates were positive for beta-lactamase production respectively. The HA-MRSA and CA-MRSA isolates had MARI values within the range of 0.3 to 1.0. Conclusion This present findings of multi-drug resistance MRSA is very worrisome as it further highlights the pressing need to keep a strict watch on MRSA emerging from this study area.
