The Influence of Pursed Lip Breathing on Dyspnea, Oxygen Saturation and Activity Tolerance on COPD Patient:Systematic Review

Systematic review has the purpose to know the influence of pursed lip breathing on dyspnea, oxygen saturation and activity tolerance on COPD patients taken from 15 journals. Information related to this research was found on some databases such as MEDLINE journals, PubMed, CINAHL, Ebsco, Elsevier ScienceDirect journal respiration in which collection of abstract and research that was identified started from 2000 until the 2015. Pursed lip breathing was an effective therapy in increasing oxygen saturation up to 1.2%, decreased dyspnea and tolerance activity. Pursed lip breathing was an easy and inexpensive therapy, which might be applied in the patients’ lives with COPD to overcome gas exchange and respiratory
A cohesive total ozone data set from the SBUV(/2) satellite system

[1] The long-term data collection of total ozone estimates from the Solar Backscatter Ultraviolet Ozone Sensors (SBUV and SBUV/2) began with the launch of SBUV on NASA's Nimbus-7 spacecraft in 1978. Following this successful demonstration, the National Oceanic and Atmospheric Administration (NOAA) adopted the slightly modified SBUV/2 instruments for placement on the afternoon Polar-Orbiting Operational Environmental Satellites (POES). The SBUV/2 instruments have flown on NOAA-9, -11, -14, and -16 in the POES series, with NOAA-16 launched in late 2000. Three more instruments are scheduled for launches in the next 6 years. While the absolute calibrations of individual instruments are good, they give total ozone accuracies of approximately 2%. However, without further adjustment, such interinstrument differences pose significant problems for atmospheric ozone trend analysis. In this paper we use the differences between total ozone estimates from the instruments during periods with overlapping coverage to account for these possible calibration biases. We use the NOAA-9 SBUV/2 record as the reference standard because of the length of its record and the amount of overlap with other instruments' records. By applying adjustments to the other data sets based on these differences, a complete, unified data set is created for use in analysis of long-term changes. The monthly-averaged total ozone time series for 50°S to 50°N and the hemispheric subsets are compared to the results from two 2-D chemistry models as a demonstration of the usefulness of the unified data sets.
G/Oe. Some spikes in the deeper section of the log can be correlated with the abundance of fractures in the basalts indicating pyrrhotite or magnetite as a product of low temperature oxidation of sulfide grains as fracture-filling

During Leg 109 a set of borehole logs was measured in DSDP Hole 395A. The susceptibility log, which was run to 600 mbsf (meters below seafloor), agreed in part with the susceptibility measurements of Leg 78B obtained with a Russian logging tool. Between 150 and 200 mbsf the log shows two zones of high susceptibility (1-1.5 x 10 G/Oe). The upper zone can be attributed to a 10-m-thick layer of magnetite-rich serpentinized peridotites. The lower high susceptibility zone is due to an increase in grain size of the titanomagnetites in a unit of massive basalts. The pillow basalts, which extend from 200 to 600 mbsf, show nearly uniform susceptibility with an average of 0.2 x 10 G/Oe. Some spikes in the deeper section of the log can be correlated with the abundance of fractures in the basalts indicating pyrrhotite or magnetite as a product of low temperature oxidation of sulfide grains as fracture-filling secondary minerals.
Calendar anomalies in Pakistan stock market

Anomalies are those irregularities that cannot be defined by the standard finance theories. In this paper, we examined the existence of an intra-month effect and weekend effect in stock returns of Pakistan stock exchange. Data has been gathered from KSE-100 index which is largest and most liquid stock market in Pakistan. Daily stock index data has been gathered from November 2, 1991, through December 31, 2014, which approximates to about 23 years data. Returns on this data were calculated and calendar anomalies were examined. Our results show that there exists an intra-month effect. Similarly, the existence of the weekend effect in the stock market is also observed. Hence, Karachi stock market shows anomalous behavior in the returns.
Effects of estrogen deficiency on liver function and uterine development: assessments of Medicago sativa's activities as estrogenic, anti-lipidemic, and antioxidant agents using an ovariectomized mouse model

Abstract We investigated the effects of Medicago sativa supplementation on the lipid profiles and antioxidant capacities of ovariectomized mice. The study was performed on white Swiss female mice that were divided into five groups: control, treated with Medicago sativa (0.75 g/kg/day), ovariectomized, ovariectomized treated with β-estradiol (1 μg/day) or with Medicago sativa. The mice were sacrificed after 3 and 8 weeks of treatment. Ovariectomy induced a decrease in overall growth, uterine atrophy, and hyperlipidemia demonstrated by increased cholesterol, triglycerides, and decreased HDL. We have shown the involvement of oxidative stress in this hepatic lesion proven by increased levels of TBARS, GPX, and GSH, and decreased levels of SOD and catalase. Treatment with Medicago sativa restores lipid balance, the activity of antioxidant enzymes and improves lipid peroxidation. This is probably due to the richness of this plant in polyphenols and flavonoids considered as an antioxidant and phytoestrogenic elements.
Proper Orthogonal Decomposition and Spectral Analysis of a Wall-Mounted Square Cylinder Wake

The flow patterns over a finite square cylinder of aspect ratio of 3 were analyzed experimentally in a subsonic wind tunnel using the time-resolved particle image velocimetry (TR - PIV) techniques. The near wake flow structures and vortex shedding characteristics were investigated using mean flow analysis, spectral analysis and proper orthogonal decomposition (POD). The cylinders were fixed on a elliptical leading edge flat plate, creating a boundary layer which interacted with the cylinder wake. The 2D PIV measurements were conducted at a low horizontal plane, z/h = 0.3, to investigate possible boundary layer interactions. Due to the complexity of the phenomena, the flow was characterized both in terms of average behavior and time-resolved velocity fields. Both symmetrical and anti-symmetrical vortices structures occur in the cylinder wake, which can be identified based on the coefficients of the first four POD modes. The results indicated that the alternating Karman vortex structures are dominant, described by the first two POD modes.
A Direct Forcing Immersed Boundary Method Based Lattice Boltzmann Method to Simulate Flows with Complex Geometry

In the present study, a lattice Boltzmann method based new immersed boundary technique is proposed for simulating two-dimensional viscous incompressible flows interacting with stationary and moving solid boundaries. The lattice Boltzmann method with known force field is used to simulate the flow where the complex geometry is immersed inside the computational domain. This is achieved via direct-momentum forcing on a Cartesian grid by combining “solid-body forcing” at solid nodes and interpolation on neighboring fluid nodes. The proposed method is examined by simulating decaying vortex, 2D flow over an asymmetrically placed cylinder, and in-line oscillating cylinder in a fluid at rest. Numerical simulations indicate that this method is second order accurate, and all the numerical results are compatible with the benchmark solutions.
First Cryomodule Test at AMTF Hall for The European X-ray Free Electron Laser (XFEL)

The Accelerator Module Test Facility (AMTF) at DESY in Hamburg is dedicated to the tests of RF cavities and accelerating cryomodules for the European X-ray Free Electron Laser (XFEL). The AMTF hall is equipped with two vertical cryostats, which are used for RF cavities testing and three test benches that will be used for tests of the accelerating cryomodules. Recently, the first cryomodule teststand (XATB3) was commissioned and the first XFEL cryomodule (XM-2) was tested by team of physicists, engineers and technicians from The Henryk Niewodniczanski Institute of Nuclear Physics Polish Academy of Sciences in Krakow, Poland, as a part of Polish in-kind contribution to XFEL. This paper describes the preparation for the cryomodule test, differences with the old teststands CryoModule Test Bench (CMTB), the cryomodule test and the test procedure updates done at the AMTF test bench. The first test of the accelerating cryomodule on the AMTF was successfully performed and the preliminary test results are presented.
Consumer Preferences for Pasture-Raised Animal Products: Results from Michigan

The pasture-based model of agriculture potentially offers opportunities for small- and medium-scale livestock producers in local, regional, and national markets. Our data indicate that many consumers value the attributes associated with locally produced pasture-raised products. We used ordered probit and binary probit analyses of these data to identify the demographic segments that showed the greatest interest in these attributes. This interest suggests a broad education and marketing effort to articulate salient attributes and to differentiate and increase the availability of these products in the marketplace.
Entrepreneurial Orientation and Effectiveness of Small and Medium Agro-Based Enterprises (SMAEs) in Malaysia - Mediating Effect of Knowledge and Network Strategies

This paper aims to explore the mediating role of knowledge and networking on entrepreneurial orientation (EO)-performance relationship among the small and medium agro-based enterprises (SMAEs) in Malaysia. The concept is somewhat vague thus knowledge-base and networking strategies are some basic features to understand in the relationships. EO, knowledge and network were entrepreneurial capabilities under the purview of the resource
A Variance-Ratio Test of Random Walk in International Stock Markets

Over the past several decades, researchers in finance, economics and other related fields conduct extensive studies to examine whether stock prices follow random walk. They, using various statistical techniques, often document mixed findings. In this paper, we test random walk hypothesis using the relatively fresh data, 34 MSCI country indexes from January 5, 1988 to December 28, 2010. We find that majority of these markets (25 out of 34 markets) follow random walk. Results, however, indicate that 4 out of 9 emerging and developing countries follow non-random walk.
The Effect of Gender-Targeted Conditional Cash Transfers on Household Expenditures: Evidence from a Randomized Experiment

This article studies the differential effect of targeting cash transfers to men or women on household expenditure on non-durables. We study a policy intervention in the Republic of North Macedonia that offers cash transfers to poor households, conditional on having their children attending secondary school. The recipient is randomised across municipalities, with payments targeted to either the mother or the father of the child. Targeting transfers to women increases the expenditure share on food by 4 to 5 percentage points. At low levels of food expenditure, there is a shift towards a more nutritious diet.

Policy implications are then derived.
Relationship Marketing: a New Approach to Marketing in the Third Millennium

Because of strong competition, fragmentation of markets, short life cycles of products and increasing customer awareness and complexity, the necessity of relationship marketing approach is felt more than ever. Relationship marketing involves creating, maintaining, and enhancing strong relationships with customers and other stakeholders. A relationship orientation implies that the focus of marketing is on retaining customers by maintaining and strengthening win-win relationships over time. Relationship marketing is more about maintaining existing customers than to attract new customers and it is just in contrast to the transactional marketing. This article first describes the concept of relationship marketing and views it from two American and European perspective. The reason for emergence of relationship marketing and its historical roots is presented and finally the most important relationship marketing models which are presented by various experts has been analyzed. Organizations and companies, using relationship marketing approach can gain competitive advantages and increase customer satisfaction and loyalty. Since customer retention, loyalty and satisfaction are crucial to survive business, so today using an approach that better achieves these goals is highly regarded. Relationship marketing as a new approach has proven in theory and practice that it is one of the most successful approaches.
Cervical human papillomavirus among women in Guangdong, China 2008‐2017: Implication for screening and vaccination

Our study aimed to analyze genotype‐specific, age‐specific prevalence, and year‐on‐year trend of cervical human papillomavirus (HPV) detection among women in Guangdong, China 2008 to 2017. A total of 199 963 women attending the gynecological department and 11 999 women attending the medical examination center at Guangdong Women and Children Hospital were included. Prevalent HPV detection significantly differed between these two groups of women (20.16% vs 17.25%; P < .001). HPV genotypes of these two populations have a large overlap, with HPV52, 16, 58, CP8304, and 53 being the dominant subtypes among gynecological outpatients and HPV52, CP8304, 58, 53, and 16 among women receiving physical examinations. The distribution of prevalent HPV detection showed a bimodal pattern across age groups among these two populations. However, prevalent HPV detection among these two populations exhibited different trends from 2008 to 2017. Our study demonstrated that prevalent HPV detection among women in Guangdong is associated with age and different from that among women from other regions of China. Our study may provide valuable data to inform cervical cancer screening and HPV vaccination programs for women in this province.
Fluid Optimization in Liver Surgery

Background: A previous study investigated the value of adding a dietitian to a geriatric discharge Liaison-Team. The scope of this study was to explore the possible economic savings of this. Methods: Patients, 70+ and at nutritional risk, were randomized to receive discharge Liaison-Team either with (intervention group, IG) or without a dietitian (control group, CG). The IG received three home visits by the dietitian during a 12-week period. Data included in the economic analysis was time spent by the dietitian, use of oral nutritional supplements (ONS) and number of hospitalization days. Results: Of the 71 included patients, 34 were in the IG, 30 patients received all three dietitian visits. Cumulated number of hospitalization days was 172 in the IG and 415 in the CG. Use of ONS was 48% in the IG and 17% in the CG (P=0.001). Estimated cost for the dietitian and ONS combined in the IG was €9,416 compared to €1,150 (ONS only) in the CG. For hospitalizations, estimated cost was €92,020 in the IG and €220,025 in the CG. Cost savings added up to €3,048 per patient in the IG. Conclusion: Adding a dietitian to a geriatric discharge Liaison-Team decreased health care costs. Study’s purposes: To reduce bleeding, hepatectomies are usually performed maintaining low central pressure (CVP) combined with extrahepatic control flow and this management can lead hemodynamic instability and reduction in oxygen delivery. This study analyzes hemodynamic changes and so the derived fluid management, in patients undergoing liver resection, through the Vigileo/FloTrac system. Basic procedures: Seventeen patients were included. Low CVP, below 4 mmHg, was reached by loop diuretics. Hemodynamic parameters were recorded and blood gas analysis was also performed. At the end of resection, fluid replacement was carried out with 500 ml of crystalloid solution in 20 minutes evaluating changes in CVP, Cardiac Index (CI) and Stroke Volume Variation (SVV). Main findings: During Pringle maneuver, Cardiac Index resulted stable through a modification in heart rate and vascular resistances (p<0.01). Only SVV significantly changed during Pringle maneuver (p=0.03) and not CVP (p=0.8). In all patients the oxygen delivery was maintained upper 600 ml/min/m2. Fluid optimization was performed with 1917 ml ± 1161 ml of crystalloid solution with a significant reduction in SVV (p<0.01) about 7% despite a CVP of 5 mmHg. Conclusions: We suppose that SVV can replace CVP in major hepatectomy management. Regarded results we can conclude that a good peripheral perfusion can be reached also with a fluid restrictive regimen avoiding overload and postoperative edema.
Evidence for an intermediate-mass black hole in the globular cluster NGC 6624

PSR B1820−30A is located in the globular cluster NGC 6624 and is the closest known pulsar to the centre of any globular cluster. We present more than 25 yr of high-precision timing observations of this millisecond pulsar and obtain four rotational frequency time derivative measurements. Modelling these higher order derivatives as being due to orbital motion, we find solutions that indicate the pulsar is in either a low-eccentricity (0.33 e 0.4) smaller orbit with a low-mass companion (such as a main-sequence star, white dwarf, neutron star or stellar mass black hole) or a high-eccentricity (e 0.9) larger orbit with a massive companion. The cluster mass properties and the observed properties of 4U 1820−30 and the other pulsars in the cluster argue against the low-eccentricity possibility. The high-eccentricity solution reveals that the pulsar is most likely orbiting around an intermediate-mass black hole (IMBH) of mass >7500 M located at the cluster centre. A gravitational model for the globular cluster, which includes such a central BH, predicts an acceleration that is commensurate with that measured for the pulsar. It further predicts that the model-dependent minimum mass of the IMBH is ∼60 000 M. Accounting for the associated contribution to the observed period derivative indicates that the γ-ray efficiency of the pulsar should be between 0.08 and 0.2. Our results suggest that other globular clusters may also contain central BHs and they may be revealed by the study of new pulsars found sufficiently close to their centres.
Wave Transformation Over Submerged Obstacles In Finite Water Depths

A two-dimensional boundary value problem of interaction of linear waves with a submerged obstacle has been solved using the Green's Identity formula to evaluate its wave reflection characteristics. The effect of the height and length of the submerged rectangular harrier on its reflection characteristics is investigated. In addition, the effect of end corners of rectangular obstacles on the oscillating nature of the reflection coefficient has been clearly brought out by comparing it with the reflection coefficients obtained for trapezoidal and half-cylindrical obstacles.
Does Wal‐Mart Sell Inferior Goods?

I estimate the aggregate income elasticity of Wal-Mart's and Target's revenues using quarterly data for 1997-2006. I find that Wal-Mart's revenues increase during bad times, whereas Target's revenues decrease, consistent with Wal-Mart selling "inferior goods" in the technical sense of the term. An upper bound on the aggregate income elasticity of demand for Wal-Mart's wares is -0.5.

The Effect of Second Language Learning Anxiety on Reading Comprehension of Iranian University Students

This study is aimed at investigating the general foreign language classroom anxiety levels of Iranian university students through administering Horwitz scale (FLCAS) in addition to examining their reading anxiety through replicating Saito’s reading comprehension anxiety scale (FLRAS). The researchers further checked the former by developing and performing a new five–point Likert type questionnaire (IFLRAS). The psychometric properties of this scale were measured and evaluated, in the first place, to confirm its reliability and validity. To carry out this study, 507 male and female university students of different major types were randomly selected from two national universities (Tehran and Shahed). Also, their reading comprehension anxiety was compared with regard to various variables such as gender, major type (indicating their language proficiency, since more proficient students are apt to be admitted in scientific and technical fields for which higher English entrance mark is required in Iran) and university (which is an indication of length of foreign language instruction, one vs. two semesters of General English course). The data were analyzed using SPSS software. The results obtained through applying Pearson Product Moment correlation, T-test, One way ANOVA, Levene and Scheffe tests revealed that there is a positive relationship between General foreign language classroom anxiety and reading comprehension anxiety(r=0.54). Furthermore, gender can positively affect students’ reading anxiety (t=-2.09). Students of different major types have different reading anxiety levels F(4,491)=6.965 p<0.01. Two universities are also distinct concerning reading comprehension anxiety levels of their students (t=-2.2o).
