EVALUATING THE EFFECT OF INDUSTRIAL EFFLUENTS ON CHEMICAL COMPOSITION OF SOIL IN VILLAGE DINGI, DISTRICT HARIPUR

The present report is an outcome of research work conducted in Dingi village, District Haripur in 2012. The research aimed to assess and analyze the effects of industrial effluents on the soil fertility of the village, investigate contributing factors responsible for soil pollution and underlying causes creating the problems. Data analysis revealed that area had problems pertaining to water and soil quality. The key factors affecting soil fertility were the careless discharge of the untreated industrial effluents from Hattar Industrial Estate (HIE) into the natural stream passing through village. The results were compared with the soil standards set by the World Wide Fund for Nature (WWF) and European Committee Commission (ECC) and all of these were exceeding the permissible limits and affecting the soil fertility. The soils were found not fit for agriculture. The investigation highlighted the need to take some effective steps to manage the monitoring program set for checking of industries by the government according to set rules and regulation

Similarities Between Classical Timelike Geodesics in a Naked Reissner-Nordstrom Singularity Background and the Behaviour of Electrons in Quantum Theory

It is generally assumed that naked singularities must be physically excluded, as they could otherwise introduce unpredictable influences in their future null cones. Considering geodesics for a naked Reissner-Nordstrom singularity, it is found that the singularity is effectively clothed by its repulsive nature. Regarding electron as naked singularity, the size of the clothed singularity (electron) turns out to be classical electro-magnetic radius of the electron, to an observer falling freely from infinity, initially at rest. The size shrinks for an observer falling freely from infinity, with a positive initial velocity. For geodetic parameters corresponding to negative energy there are trapped geodesics. The similarity of this picture with that arising in the Quantum Theory is discussed.Comment: 8 pages, 6 figure

Differences in delivery of prehospital ambulance care comparing non-white versus white patients with suspected cardiac chest pain: cross-sectional study

Introduction Quality implies equitable care irrespective of ethnicity. There have been few previous studies investigating quality of prehospital cardiac care by ethnicity. We aimed to investigate whether prehospital care for suspected cardiac pain varied by ethnicity. Methods We conducted a cross-sectional analysis of retrospective electronic clinical data for patients with chest pain over one year (August 2011 to July 2012) extracted from a single regional ambulance service. This included patient demographic data (ethnicity, age, sex, deprivation), clinical measurements (blood pressure, respiratory rate, pain assessment, temperature, blood glucose, oxygen saturation), drugs (aspirin, nitroglycerin, Entonox, morphine) and outcomes such as transportation to hospital or referral to primary care. We used multivariate regression to investigate differences in care by ethnicity comparing non-white with white patients. Results There were 7046 patients with suspected cardiac chest pain, with 4825 who had ethnicity recorded including 4661 (96.6%) white, 164 (3.4%) non-white (2221 patients had missing data for ethnicity). Non-white patients were similar in sex (p=0.63) and socioeconomic group (p=0.07) but significantly younger in age (p<0.001) than white patients. After correcting for age, sex, socioeconomic status and whether transported to hospital, non-white patients were similar to white patients in recording of blood pressure, pain score or electrocardiogram but significantly more likely to have temperature (77.4 vs.69.8%), blood glucose (78.7 vs. 69.4%), and oxygen saturation (85.4 vs. 80.7%) recorded. There were no differences in aspirin, nitroglycerin, Entonox or morphine treatment but non-white patients were less likely than white patients to be transported to hospital (93.3 vs. 94.4, p=0.02). Conclusion We found differences in prehospital ambulance care for non-white compared with white patients with cardiac pain that could be due to recording bias, varying clinical condition or provider management. Further analysis should involve larger and more complete datasets to explore ethnic differences in greater detail

Leadership, innovation and engagement in quality improvement in the Ambulance Services Cardiovascular Quality Initiative: cross sectional study

Introduction: Clinical leadership and organisational culture are important contextual factors for successful Quality Improvement (QI) programmes. The relationship between these and with organisational performance is complex and poorly understood. We aimed to explore the relationship between leadership, culture of innovation, and clinical engagement in QI for organisations participating in a large-scale national ambulance Quality Improvement Collaborative (QIC). Methods: We used a cross sectional survey design. An online questionnaire was distributed to 22,117 frontline ambulance staff across all 12 ambulance services in England. Scores (0-100%) were derived for each key aspect: clinical leadership; culture of innovation; use of QI methods; and effectiveness of QI methods. Responses to an open-ended question were analysed and complemented the quantitative findings. Results: There were 2,743 (12%) responses from 11 of 12 participating ambulance services. Despite only a small proportion of responders (3%) being directly involved with ASCQI, leadership behaviour was significantly higher for ASCQI members than for non-ASCQI members. Involvement in ASCQI was not significantly associated with responders’ perceptions of the culture of innovation of their organisation, which was generally considered to be poor. ASCQI members were significantly more likely to use QI methods but overall uptake of QI methods was low. The use of QI methods was also significantly associated with leadership behaviour and service tenure. Limitations: There was a low response rate, although sufficient responses to enable comparison of those who participated in ASCQI with those who did not. Conclusion and recommendations: Although participants reported a lack of organisational culture of innovation, considered a prerequisite for QI, the collaborative achieved significant wide-scale improvements in prehospital care for myocardial infarction and stroke. We postulate that improvement was mediated through a ‘QI subculture’ developed from ASCQI’s distributed leadership and network. Further research is needed to understand success factors for QI in different complex healthcare environments

Asymptotic Behaviour of the Proper Length and Volume of the Schwarzschild Singularity

Though popular presentations give the Schwarzschild singularity as a point it is known that it is spacelike and not timelike. Thus it has a "length" and is not a "point". In fact, its length must necessarily be infinite. It has been proved that the proper length of the Qadir-Wheeler suture model goes to infinity [1], while its proper volume shrinks to zero, and the asymptotic behaviour of the length and volume have been calculated. That model consists of two Friedmann sections connected by a Schwarzschild "suture". The question arises whether a similar analysis could provide the asymptotic behaviour of the Schwarzschild black hole near the singularity. It is proved here that, unlike the behaviour for the suture model, for the Schwarzschild essential singularity $\Delta s$ $\thicksim$ $K^{1/3}\ln K$ and $V\thicksim$ $K^{-1}\ln K$, where $K$ is the mean extrinsic curvature, or the York time.Comment: 13 pages, 1 figur

Technologies and solutions for location-based services in smart cities: past, present, and future

Location-based services (LBS) in smart cities have drastically altered the way cities operate, giving a new dimension to the life of citizens. LBS rely on location of a device, where proximity estimation remains at its core. The applications of LBS range from social networking and marketing to vehicle-toeverything communications. In many of these applications, there is an increasing need and trend to learn the physical distance between nearby devices. This paper elaborates upon the current needs of proximity estimation in LBS and compares them against the available Localization and Proximity (LP) finding technologies (LP technologies in short). These technologies are compared for their accuracies and performance based on various different parameters, including latency, energy consumption, security, complexity, and throughput. Hereafter, a classification of these technologies, based on various different smart city applications, is presented. Finally, we discuss some emerging LP technologies that enable proximity estimation in LBS and present some future research areas
