The Impact of Some Determinants of the External Financial Environment on the Financial Sustainability of Business Companies: An Analytical Study in a Sample of Companies Listed in the Iraqi Stock Exchange

The aim of the research is to analyze the level of financial sustainability in companies and the effect of some determinants of the external financial environment on the financial sustainability of Iraqi business companies. The research was based on a set of determinants (inflation, interest rates, per capita income, market share), and Fulmer model was used to measure financial sustainability. For companies and their ability to continue. The Iraq Stock Exchange was relied on as a research community, and five of the industrial companies included in it were identified as a research sample. Data contained in their financial statements for period (2010-2019). Therefore, the mechanism for building and analyzing standard models will depend on Sectional time-series data ((collected) Panel Data or longitudinal data). The results of the research showed that the research sample companies are characterized by financial sustainability. The results also showed no impact on the determinants of the external financial environment combined on the financial sustainability of the research sample companies. In relation to the analysis of the effect determinants of the external financial environment separately on the financial sustainability, the results of the research concluded that each of the variables of the interest rate and the market share of the company affect the financial sustainability of the company individually. Yet, the inflation rate and the average per capita income do not have a significant effect individually on the financial sustainability for the companies.
Algorithm study of fast and accurate time-delay estimation with fine interpolation of correlation peak

A new way of computing accurate correlation peak to increase accuracy of time-delay estimation is studied. A barrier affection caused by standard FFT calculation is reduced by calculating signal's fine spectrum with a modified Chirp z transform. A new fast algorithm of the transform FICP (Fine Interpolation of Correlation Peak) was created to compute waveform of the main correlation peak only using the main segment of the cross power spectrum. The peak can be interpolated in any accuracy without increasing calculation. The accuracy of TDE(Time-Delay Estimation) has been increased. With this way and model, interference coursed by broadband band noise can be reduced by using limited spectrum of the signal. The correlation peak will be detected precisely.
Characterisation of the Doxorubicin pump of Streptomyces peucetius : the DrrA component of the DrrAB ATP-binding cassette transporter.

The emergence of antibiotic resistant microorganisms is one of the most concerning problems in health welfare, and particularly, that of multi drug resistance. The active efflux of compounds from the cell is one of the key strategies used by microorganisms to avoid the noxious effects of toxic compounds and has become one of the most important mechanisms of multiple resistance, such transport processes being catalysed by an array of membrane associated proteins. ATP-Binding Cassette Transporters, that carry out an energy dependent active transport process by which substances cross the cell membrane on the hydrolysis of ATP, also display the ability to translocate a number of unrelated molecules, including antibiotics. These transporters have been identified as one of the largest and most widely distributed families of such transmembrane transport systems. Virtually ubiquitous in nature, ABC transporters have been found in the genomes of every organism from the simplest archea through to man. The fact that they contribute the main pathway for resistance to anticancer drugs in humans highlights their importance and urgent need to study them. In addition to the well known groups of antibiotics produced by members of the Streptomyces genus, that include aminoglycosides, tetracyclines, chloramphenicol, and some (3-lactams, which inhibit the protein synthesis or the proper formation of bacterial cell walls, the species Streptomyces peucetius produces the antibiotics doxorubicin and daunorubicin. These latter compounds are classified into the anthracyclines group and possess antitumoral activity, expanding the arsenal of compounds with different activity produced by Streptomyces. The manner, in which S. peucetius avoids the effect of the antitumorals it produces, is by pumping them out of the cells, and the system that it utilises is that of an ABC transporter. In this system two subunits are present, one of them, DrrA, a peripheral membrane protein that acts as the energy-transducing component, and the other, DrrB, the membrane carrier. This type of permease carries out export of antibiotics in an ATP-dependent manner. The expression of DrrA in E. coli proved to be a challenging enterprise as only low yields were obtained for DrrA at 16 °C, that were only improved when DrrA was fused to Thioredoxin. The over expression and purification of DrrA allowed a partial characterisation of the catalytic activity of DrrA fused to Thioredoxin, with traditional biochemical methods, complemented by additional characterisation assays in wild type DrrA. The characterisation was based on assays of the ATPase activity of Thio- DrrA and DrrA, which displayed a measurable catalytic activity compatible with a role in energising transmembrane transport. These proteins were shown to be cation dependent ATPases able of binding and hydrolysing ATP in a similar manner to the NBD proteins of well-characterised prokaryotic ABC transporters, also showing common features to other NBD's.
Numerical and Experimental Investigation of Flow Field in A 330MW Opposed Firing Boiler

In this paper, the flow field in opposed firing boiler is numerically simulated by means of k e two equations model. The simulation results indicate that the opposed firing way in this kind of boiler solves efficiently the problem of the temperature deviation at the furnace exit, which decreases greatly the possibility of tube rupture of the superheater and reheater in horizontal flueway due to exceedingly high temperature compared with that of the tangentially fired furnace. And the numerical results represent the experimental ones well. Figs 5, table 1 and refs 5.
An Interleaving Double-switch Buck-Boost Converter for PV Grid-connected Inverter

Charactered with noninverting and step up/down conversion,the double-switch Buck-Boost converter is suit for the front stage of the two-stage photovoltaic (PV) grid-connected inverter. But,the large inductor is needed in conventional control strategy,and the sophisticated control logic and difficult compensation technique for smooth transitions are included in combinatorial control strategy. In order to reduce the inductor and simplify the control logic,an interleaving control strategy was proposed. The operation principle of the proposed control strategy and the characteristics were analyzed,and several indexes in different control strategies were compared. Finally,the interleaving operation principle was verified by a 3 kW two-stage PV grid-connected inverter prototype.

Human movement patterns of different racial-ethnic and economic groups in U.S. top 50 populated cities: What can social media tell us about isolation?

ABSTRACT Many studies have proven that human movement patterns are strongly impacted by individual socioeconomic and demographic background. While many efforts have been made on exploring the influences of age and gender on movement patterns using social media, this study aims to analyse and compare the movement patterns among different racial-ethnic and economic groups using social media (i.e. geotagged tweets) from the U.S. top 50 populated cities. Results show that there are significant differences in number of activity zones and median travel distance across cities and demographic groups, and that power-laws tend to be captured in both spatial and demographic aspects. Additionally, the analysis of outbound-city travels demonstrates that some cities have slightly stronger interaction with others, and that economically disadvantaged populations and racial-ethnic minorities are more restricted in long distance travels, indicating that their spatial mobility is more limited to the local scale. Lastly, an economically-segregated movement pattern is discovered – upper-class neighbourhoods are mostly visited by the upper-class, while lower-class neighbourhoods are mainly accessed by the lower-class – but some racial-ethnic groups can diversify this segregated pattern in the local scale.
Effects of Earnings Management to Corporate Tax Avoidance

Among vital expenses of the company, that affect profits and shareholders value, is corporate income tax (CIT). And among ways to maximize market value, firm management consider to intervene firm profits to save tax costs to cause after tax return rate to go up to attract investment. The study purpose is analyzing effects from earnings management on tax avoidance level of listed firms on Vietnam stock market. By using multivariate regression analysis, the study results show us that when earnings management higher, the level of corporate income tax avoidance will be higher. One of the earnings management goals is to increase the rate of return after taxes in order to maximize shareholder value and attract investment. Therefore, managers will focus on adjusting profits to the most profitable and maximum income tax saving. This research studies the effect of earnings management to corporate income tax avoidance in Vietnam. To examine this relationship, we examined the impact of discretionary accruals on the effective tax rate with a sample of 496 firm – years in the period of 2016-2018. The research results find a positive relationship between earnings management and corporate income tax avoidance, i.e., the more profit-adjusting behaviors companies have through discretionary actuals, the lower the effective tax rate will be. LAst but not least, impact factors on income tax include inventory and capital intensity and firm size whereas non0imapct factors include external auditors type and leverage.
Simulation on Flow Control for Drag Reduction of Revolution Body Using Bionic Dimpled Surface

Numerical simulations on drag reductions for the dimpled and the smooth revolution bodies were performed and compared with SST k-ω turbulence model,to explain the reasons of friction and base drag reductions on the bionic dimpled surface and the control behaviors to boundary layer near wall of the revolution body.The simulated results show that the dimpled surface arranged on the rearward of the revolution body reduces the skin friction drag by 8.05%,the base drag by 1.9% and the total drag by 6.24% at Mach number 0.4;the dimpled surface reduces the skin friction drag through reducing the velocity gradient and turbulent intensity,and reduces the base drag through weakening the pumping action on the flow behind the revolution body caused by the external flow;the flow control behavior on boundary layer produced by dimpled surface displays that the low speed rotating vortexes in the dimples like vortex cushions,which segregate the external flow and the revolution body;and the low speed rotating vortexes forming in the bottom of dimples can produce negative skin friction against to the other area,which can be considered a accessional impetus.

Laboratory performance of warm mix asphalt with high RAP content

Road construction using warm-mix asphalt (WMA) has been rapidly gaining popularity in the United States. The number of WMA projects constructed has grown aggressively and steadily. Parallel to this rapid growth in WMA construction is the attention placed on usage of high percent of reclaimed asphalt pavement (RAP) in asphalt construction. A laboratory investigation took place on the behavior of high RAP mixes with three WMA technologies: water foaming, a chemical additive, and an organic additive. The work included mix design, moisture damage evaluation, and rutting evaluation using the Indirect Tensile Tester, Superpave Shear Tester (SST) and Model Mobile Load Simulator Third Scale (MMLS3). This research indicates that it is possible to produce WMA with sufficient moisture damage and rutting resistance. However, a mix design established for hot mix asphalt (HMA) does not necessarily produce satisfactory performance when used with WMA, and it is important that moisture damage and rutting susceptibility of WMA be evaluated for any mix design even though that mix design might have demonstrated satisfactory performance for HMA. Optimum binder content developed from HMA could be applied to WMA but air void must be checked for WMA at the design number of gyrations to ensure it does not differ significantly from the HMA design air void. A difference in air void of no more than ±0.75 percent is recommended. Larger differences in air void require adjustments to the binder content.

Based on the analysis, some possible solutions for these issues are listed, and some important research tendencies of these approaches are presented. Lastly, the achievements on emergency evacuation modeling are concluded, and some attentive questions in actual evacuation modeling are given.
Heterosis counteracts hybrid breakdown to forestall speciation by parallel natural selection

In contrast to ecological speciation, where reproductive isolation evolves as a consequence of divergent natural selection, speciation by parallel natural selection has been less thoroughly studied. To test whether parallel evolution drives speciation, we leveraged the repeated evolution of benthic and limnetic ecotypes of threespine stickleback fish and estimated fitness for pure crosses and within-ecotype hybrids in semi-natural ponds and in laboratory aquaria. In ponds, we detected hybrid breakdown in both ecotypes but this was counterbalanced by heterosis and the strength of post-zygotic isolation was nil. In aquaria, we detected heterosis only in limnetic crosses and breakdown in neither ecotype, suggesting that hybrid incompatibilities are environment-dependent for both ecotypes and that heterosis is environment-dependent in benthic crosses. Heterosis and breakdown were 3× greater in limnetic crosses than in benthic crosses, contrasting the prediction that the fitness consequences of hybridization should be greater in crosses among more derived ecotypes. Consistent with a primary role for stochastic processes, patterns differed among crosses between populations from different lakes. Yet, we observed qualitatively similar patterns of heterosis and hybrid breakdown in benthic crosses and limnetic crosses when averaging the lake pairs, suggesting that the outcome of hybridization is repeatable in a general sense.
A Primitive for Manual Hatching

In art, hatching means drawing patterns of roughly parallel lines. Even with skill and time, an artist can find these patterns difficult to create and edit. Our new artistic primitive—the hatching shape—facilitates hatching for an artist drawing from imagination. A hatching shape comprises a mask and three fields: width, spacing, and direction. Streamline advection uses these fields to create hatching marks. A hatching shape also contains barrier curves: deliberate discontinuities useful for drawing complex forms. We explain several operations on hatching shapes, such as the multi-dir operation, an easy way to depict 3D form using a hatching shape’s direction field. We also explain the modifications to streamline advection necessary to produce hatching marks from a hatching shape.
Impact of Total Ischemic Time on the Recovery of Regional Wall Motion Abnormality after STEMI in the Modern Reperfusion Era

Background Total ischemic time (TIT) is an important factor for predicting mortality among patients with ST-segment elevation myocardial infarction (STEMI). However, the correlation between TIT and the extent of wall motion abnormality has not been well studied. Therefore, we investigated changes in the wall motion score index (WMSI) value based on TIT in STEMI patients who underwent primary percutaneous coronary intervention (PCI) and subsequent transthoracic echocardiography. Methods STEMI patients who underwent primary PCI and follow-up coronary angiography were analyzed after the exclusion of cases of in-stent restenosis (ISR). WMSI values were calculated by dividing the sum of scores by the number of segments visualized. Results A total of 189 patients underwent primary PCI for STEMI, and 151 had no ISR with a median follow-up of 12.3 months. TIT was 180 (117–369) minutes in a subset of 151 patients (mean age of 62 years; 76% male). Among patients without ISR, 109 (72%) demonstrated a decrease in the WMSI value during the follow-up period. The WMSI values of patients with TITs of 180 minutes or less were significantly decreased relative to those among patients with TITs of greater than 180 minutes (p=0.020). Among patients with TITs of 180 minutes or less, the TIT was significantly shorter among those with a reduction in the WMSI value than among those with an increase in the WMSI value (106 [81–124] vs. 133 [100–151] minutes; p=0.018). TIT was an independent predictor for a reduction in the WMSI value among these patients (adjusted hazard ratio: 0.976 (0.957–0.995); p=0.016). Conclusions In the modern reperfusion era of STEMI, patients with TITs of 180 minutes or less experienced a significant degree of recovery from regional wall motion abnormalities.
An Introduction of Aperture Coupled Microstrip Slot Antenna

A microstrip slot antenna is very small and lightweight still it has the problem of back radiation due to which power loss occurs and the SAR increases. To reduce the back lobe a technique introduces i.e. aperture coupled microstrip slot antenna which reduces the back lobe as well as increases the bandwidth of the antenna. Aperture coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture.
