Phenolic compounds are listed under priority pollutants by US EPA, and their concentration in effluent of coke oven industries reached to 1000 mg l-1 . However, investigation on biodegradation of phenolics from coke oven wastewater is found to be scanty. Therefore, an indigenous pseudomonas species with high toxicity tolerance and phenolic degradation abilities has been isolated from coke oven wastewater. In order to enhance the efficiency of phenol and to the study the interaction effect exists among them the significant media components are optimized employing response surface methodology (RSM) and central composite design (CCD RSM. Result reveals that MgSO4 plays considerable influence on biodegradation of phenol degradation by the indigenous pseudomonas species. Further, among the three independent variables, interaction effect between MgSO4 and FeCl3 found to be significant on degradation of phenol. The optimum values of the media constituents are as follows: 0.094 mgl-1 of NaCl, 0.019 mgl-1 FeCl3 and 0.1681 mgl-1 of MgSO4. Almost completely biodegradation of phenol is achieved at 900 mgl-1 of phenol within a short time period of 24h. Further, at this optimized culture condition almost completely degradation of phenol was achieved even at a very high initial concentration of 1500 mgl-1 within a shorter time period of 95h. Thus, indigenous Pseudomonas species found to be a potential candidate for degradation of high concentration of phenol from of coke oven wastewater

Phenolic compounds are listed under priority pollutants by US EPA, and their concentration in effluent of several industries reached to 1000 mg l-1. However, investigation on biodegradation of phenolics from coke oven wastewater is found to be scanty. Therefore, an indigenous pseudomonas species with high toxicity tolerance and phenolic degradation abilities is isolated from coke oven wastewater. In order to enhance the rate of cresol biodegradation efficiency various culture conditions; such as pH, agitation speed (RPM) and inoculums size (OD600nm) is optimized by using response surface methodology (RSM) and central composite design (CCD) . Result revealed that agitation speed and inoculums size (OD600nm) played considerable influence on phenol degradation by the indigenous pseudomonas species. Further, among the three independent variables, interaction effect between pH and agitation speed (RPM) found to be significant on degradation of phenol. At the RSM optimized settings of pH 7.5, agitation speed 168 rpm, and inoculums size 1.3 (OD600nm), almost completely biodegradation of phenol is achieved at 700 mgl-1 of phenol within a short time period of 12h. Further, at this optimized culture condition more than 99 % of phenol degradation along with 95% of toxicity removal was attained at an initial phenol concentration of 1500 mgl-1 within a shorter time period of 94h. Thus, indigenous pseudomonas species can be possible used for the treatment of coke oven wastewater.

The Impact

Fiscal councils are independent institutions that play an important role in execution of fiscal rules and budgetary discipline through their realistic and unbiased macroeconomic and budgetary analysis and projections. It is important that the fiscal councils have easy access to the media to ensure that their analyses reach the wider public, and influence creators of fiscal policy. This paper analyzes the influence of fiscal councils on budget balance and public debt in period before and after financial crisis. The member states that had functioning fiscal councils before the financial crisis, on average, manage their public finances better than those who founded them after the beginning of crisis. Additionally, supervision of the enforcements of fiscal rules from fiscal boards is already showing positive results in this short time period. Fiscal councils are extremely important to ensure a healthy basis for conducting fiscal policy and to decrease the influence of politics on public finance management.

According to the latest forecasts, it will take 10 years for the world economy to get back to “decent shape”. Some more critical estimates suggest that the whole western world will have a “colossal mess” within the next 5–10 years. Regulators of some major countries significantly and over a short time‑period changed their forecasts for the worse which means that uncertainty in the outlook for the future persists. Indeed, the intensive anti‑crisis measures have reduced the severity of the past problems, however the problems themselves have not disappeared. Moreover, some of them have become more intense — the eurocrisis, excessive debts, global liquidity glut against the backdrop of its deficit in some of market segments. As was the case prior to the crisis, derivatives and high‑risk operations with “junk” bonds grow; budget problems — “fiscal cliff” in the US — and other problems worsen. All of the above forces the regulators to take unprecedented (in their scope and nature) steps. Will they be able to tackle the problems which emerge?

Objective: To study the effect of short-term use of oral contraceptive pills on intra-ocular pressures of women of childbearing age.   Methods: It was a comparative observational study, conducted at Arif memorial teaching hospital and Allied hospital Faisalabad for a period of six months. Hundred female subjects were divided into two groups of 50 each. Group A, included females, who had been taking oral contraceptive pills (OCP) for more than 6 months and less than 36 months. Group B, included 50 age-matched controls, who had never used OCP. Ophthalmic and systemic history was taken. Careful Slit lamp examination was performed and intraocular pressures (IOP) were measured using Goldman Applanation tonometer. Fundus examination was done to rule out any posterior segment disease. After collection of data, we analyzed and compared the intra ocular pressures between the two groups by using ANOVA in SPSS version 21.   Results: Average duration of using OCP was 14.9 months. There was no significant difference of Cup to Disc ratios between the two groups (p= 0.109). However, significant difference was noted between the IOP of OCP group and controls. (p=0.000). Conclusion: OCP significantly increase IOP even when used for short time period.

AbstractThe COVID-19 pandemic has forced governments to impose major restrictions on individual freedom in order to stop the spread of the virus. With the successful development of a vaccine, these restrictions are likely to become obsolete—on the condition that people get vaccinated. However, parts of the population have reservations against vaccination. While this is not a recent phenomenon, it might prove a critical one in the context of current attempts to manage the COVID-19 pandemic. Consequently, the task of designing policies suitable for attaining high levels of vaccination deserves enhanced attention. In this study, we use data from the Eurobarometer survey fielded in March 2019. They show that 39% of Europeans consider vaccines to cause the diseases which they should protect against, that 50% believe vaccines have serious side effects, that 32% think that vaccines weaken the immune system, and that 10% do not believe vaccines are tested rigorously before authorization. We find that—even when controlling for important individual-level factors—ideological extremism on both ends of the spectrum explains skepticism of vaccination. We conclude that policymakers must either politicize the issue or form broad alliances among parties and societal groups in order to increase trust in and public support for the vaccines in general and for vaccines against COVID-19 in particular, since the latter were developed in a very short time period and resulted—in particular in case of the AstraZeneca vaccine—in reservations because of the effectiveness and side effects of the new vaccines.

AbstractThe present study investigated the influence of related and unrelated emotions on judgments about a news article. An experimental study was designed to manipulate both the relatedness of an elicited emotion (i. e., anger) to the news article and processing depth. Following mood and emotion effects theory, related anger was expected to have a stronger effect on judgments about the media message than unrelated anger. Processing depth was expected to moderate this effect. The results showed a main effect of relatedness and a main effect of processing depth, but the interaction effect was not found. Implications of the findings for understanding how emotions influence the processing of media stimuli are discussed.

Abstract Background Platypnoea–orthodeoxia syndrome (POS) is an uncommon condition characterized by dyspnoea and arterial desaturation in the standing or sitting position that improves in the supine position. Case summary We report two cases of POS caused by an atrial septal defect (ASD) and a patent foramen ovale (PFO). Both cases reported a recent decrease in body weight of more than 10 kg in a short time period. Transoesophageal echocardiography (TOE) with agitated saline bubble study revealed and a large amount of contrast bubble through the ASD (Patient 1) or the PFO (Patient 2) from the right atrium to the left atrium in the sitting position. Both patients were diagnosed by the finding of positional dyspnoea and the results of TOE using agitated saline bubble contrast. Discussion Taken together, their presentations suggest that weight loss in a short time period could be a pathogenic factor for POS.

This article briefly reviews American and British literature on welfare dynamics and examines the concepts of welfare dependency and ‘dependency culture’ with particular reference to lone parents. Using UK benefit data sets, the welfare dynamics of lone mothers are examined to explore the extent to which they inform the debates. Evidence from Housing Benefits data show that even over a relatively short time period, there is significant turnover in the benefits-dependent lone parent population with movement in and out of income support as well as movement into other family structures. Younger lone parents and owner-occupiers tend to leave the data set while older lone parents and council tenants are most likely to stay. Some owner-occupier lone parents may be relatively well off and on income support for a relatively short time between separation and a financial settlement being reached. They may also represent a more highly educated and highly skilled group with easier access to the labour market than renters. Any policy moves paralleling those in the United States to time limit benefit will disproportionately affect older lone parents.

World War I advanced the development of aviation from the concept of flight to the use of aircraft on the battlefield. Fighter planes advanced technologically as the war progressed. Fighter pilot aces Francesco Baracca and Manfred von Richthofen (the Red Baron) were two of the most famous pilots of this time period. These courageous fighter aces skillfully maneuvered their SPAD and Albatros planes, respectively, while battling enemies and scoring aerial victories that contributed to the course of the war. The media thrilled the public with their depictions of the heroic feats of fighter pilots such as Baracca and the Red Baron. Despite their aerial prowess, both pilots would eventually be shot down in combat. Although the accounts of their deaths are debated, it is undeniable that both were victims of traumatic head injury.
