Do Multiple Isolated Vertebral Thoracolumbar Transverse Process Fractures Increase the Risk of Ligamentous Injury and Surgical Intervention in the Setting of Trauma?  [PDF]
Nickalus Khan, Jonathan Reding, Matthew Gilbert, Michael S. Muhlbauer, L. Madison Michael
Open Journal of Modern Neurosurgery (OJMN) , 2018, DOI: 10.4236/ojmn.2018.81006
Abstract: Background: Isolated thoracolumbar vertebral transverse process fractures (TPF) are often considered a stable injury. However, the use of advanced imaging such as magnetic resonance imaging and spine specialist consultation are often ordered as part of the routine workup of these fractures. The routine ordering of advanced imaging, spine specialist consultation, and delayed mobilization causes unnecessary economic and clinical burdens to patients and the overall healthcare system. Purpose: To determine if a higher number of isolated TPFs (iTPFs) lead to an increase in ligamentous injury to the spine, and whether ligamentous injury—if present—requires surgical intervention. Methods: The retrospective review was performed from 2009 to 2015, using a surgical trauma database to identify patients with greater than 3 isolated TPF (iTPF) to determine if iTPF leads to an increase in ligamentous injury to the spine and if this increase leads to increased surgical intervention. Results: A total of 102 patients were identified with complete follow up at 6 - 8 weeks post injury. The majority of the included patients suffered from blunt trauma. There was a small rate of ligamentous injury (n = 7, 7%) that did not require additional treatment. None of the fractures included were considered unstable. None of the patients included required surgical intervention during their hospital visit or in follow up visits. Conclusion: iTPFs are a stable injury to the thoracolumbar spine. There is a small rate of associated ligamentous injury that does not change the management or require further interventions. Thoracolumbar iTPFs do not automatically need spine specialist consultation and advanced imaging techniques.
Supported TritonX-100 Polyaniline Nano-Porous Electrically Active Film onto Indium-Tin-Oxide Probe for Sensors Application  [PDF]
Raju Khan
Advances in Chemical Engineering and Science (ACES) , 2011, DOI: 10.4236/aces.2011.13021
Abstract: Supported tritonX100 polyaniline nano-porous electrically active film has been fabricated successfully onto indium-tin-oxide conducting probe using electrochemical polymerization process. The doping of TX-100 in the polymeric network of PANI was suggested using cyclic voltammeter, UV-vis spectroscopy, and Fourier Transform Infrared spectroscopy. The change in the surface morphology of PANI thin film due to incorporation of tritonX-100 was investigated using Atomic Forced Microscopy and porosity has been confirmed scanning electron microscopy, respectively. The surface morphology, uniformly disperse hexagonal close packing of TX-100 in PANI matrices due to the incorporation of TX-100 in polymeric network of PANI was confirmed by Atomic Force Microscopy. The electrical conductivity of PANI-TX-100 increases from 1.06 x 10-2 S/cm-1 to 4.95 x 10-2 S/cm-1 as the amount of TX-100 increases during the polymerization. The change in the morphology and electrical conductivity of PANI due to incorporation of TX-100 prove as a promising material for the sensing application.
A Novel, Safe Way of Removing Non-Deflatable Bladder Catheter  [PDF]
Ziauddin Khan, Umair Tahir Khan, Imran Khan, Tahir Naeem Khan
Open Journal of Urology (OJU) , 2012, DOI: 10.4236/oju.2012.24044
Abstract: Non-deflated balloon of a transurethral inserted bladder catheter is a problem that could be difficult to manage, especially in males. A variety of methods have been described to puncture the balloon and remove the catheter, though these can be associated with complications. We illustrate a simple and a safe method to overcome this problem using a flexible cystoscope under local anaesthesia.
Book Review on Pakistan and the New Nuclear Taboo: Regional Deterrence and the International Arms Control Regime  [PDF]
Zafar Khan
Advances in Historical Studies (AHS) , 2013, DOI: 10.4236/ahs.2013.21001
Abstract: Pakistan has always been the focus of international community, strategists, analysts, and academic scholars on various issues more especially on the nuclear issue since Pakistan has embarked its journey from covert to overt nuclearisation of South Asia. Any work in relation to Pakistan’s nuclear weapons program ranging from its nuclear policy to its nuclear security has gained a great significance in the realm of politics and international studies. Rizwana Abbasi’s maiden volume entitled, Pakistan and the New Nuclear Taboo: Regional Deterrence and the International Arms Control Regime is a welcome contribution that would certainly be embraced by the Pakistani security planners and strategic community in general and the wider international audience in particular. The key aim of this book is that norms, values, and regime still matter despite the presence and influence of hard core realism and neo-realism.
Comparison between the Personality Dimensions of Delinquents and Non-Delinquents of Khyber Pukhtunkhwa (KPK), Pakistan  [PDF]
Sehrish Khan
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.25027
Abstract: This study was an attempt to find out the comparison between the personality dimensions of delinquents and non delinquents of Khyber Pukhtonkhwa (KPK). Eysenck personality Questionnaire (junior) (Urdu Version 2007) was administered on the sample of 400 (Delinquents = 200, non-delinquents = 200). Delinquents were the inmates in different jails of KPK while non-delinquents
were the students of different colleges of KPK. It was hypothesized that the delinquents will score higher on all the four dimensions of Eysenck personality scale as compared to non delinquents. Findings of the study confirmed the said hypothesis. It was proved that delinquents have higher scores of psychoticism, neuroticism, extraversion, and lie as compared to non-delinquents. The findings of this study can help the parents, teachers, and the law departments to focus on the construction of healthy personality so that the rate of crimes among adolescents can be minimized.
Head Teachers’ Beliefs and Practices about Teaching and Learning in Pakistani Public Schools  [PDF]
Asif Khan
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.622237
Abstract: Very limited research focusing on instructional contribution of Pakistani public school administrators has emerged from the educational landscape of Pakistan. Therefore, the present study highlights some of the core issues related to the instructional contribution of two head teachers situated in public schools. While focusing on instruction-related practices, the two case studies particularly examine the head teachers’ engagements in supervisory processes and in-school capacity development initiatives. The study notes that despite the presence of required human and physical resources, the two head teachers make limited contributions towards the instructional quality of their respective schools. A vague understanding about their roles, a limited capacity building opportunities, and an absence of an accountability mechanism prevent the two head teachers from becoming more involved in the said processes. The study maintains that a new organizational culture needs to be introduced that re-conceptualizes the role of Pakistani head teachers while emphasizing the above-mentioned factors.
On Some I-Convergent Double Sequence Spaces Defined by a Modulus Function  [PDF]
Vakeel. A. Khan, Nazneen Khan
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.55A006
Abstract: In 2000, Kostyrko, Salat, and Wilczynski introduced and studied the concept of I-convergence of sequences in metric spaces where I is an ideal. The concept of I-convergence has a wide application in the field of Number Theory, trigonometric series, summability theory, probability theory, optimization and approximation theory. In this article we introduce the double sequence spaces \"\" and \"\",for a modulus function f and study some of the properties of these spaces.

Can Simple Preoperative Hemoglobin Testing Screen Symptomatic Anemia in Patients Undergoing Ambulatory Surgeries in Third World Countries?  [PDF]
Sobia Khan, Mueen Ullah Khan, Khalid Samad
Open Journal of Anesthesiology (OJAnes) , 2012, DOI: 10.4236/ojanes.2012.24034
Abstract: Background: Patients coming for ambulatory surgeries are mostly healthy adults and asymptomatic anemia in these patients is rare. According to international standards, perioperative period is not an appropriate setting to screen and investigate the cause of asymptomatic anemia, but in third world countries where iron deficiency is rampant, it is generally required as per local hospitals policy to test hemoglobin levels prior to any surgery in order to prevent morbidity. The purpose of our study is to look at the prevalence of anemia in patient undergoing minor elective ambulatory surgeries. Method: This was a cross sectional observational study conducted at tertiary care unit, Karachi, Pakistan. A total of 385 ASA-I (American Society of Anesthesiologist) and II patient’s age ranged 18 - 60 years, scheduled for day care surgical procedures were enrolled in the study. Results: Anemia was detected in 74 (19.2%) patients and its prevalence was found to be higher in females and in patients above 50 years of age. However, the presence of anemia did not have any influence on the perioperative outcomes or management. Conclusion: The routine preoperative hemoglobin testing does not have any effect on the perioperative outcomes in asymptomatic patients who are planned for elective day care surgeries.
Instability of Thermally Conducting Self-Gravitating Systems  [PDF]
Shaista Shaikh, Aiyub Khan
Journal of Modern Physics (JMP) , 2010, DOI: 10.4236/jmp.2010.110010
Abstract: The gravitational instability of a thermally conducting self-gravitating system permeated by a uniform and oblique magnetic field has been analyzed in the framework of Tsallis’ nonextensive theory for possible mod-ifications in the Jeans’ instability criterion. It is concluded that the instability criterion is indeed modified into one that depends explicitly on the nonextensive parameter. The influence of thermal conductivity on the system stability is also examined.

Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.37062
Abstract: Environmental degradation and unethical human intervention in the natural system has increased the concern for the betterment of healthy living. The deterioration of aquatic system is commonplace in the developing world. The present paper shows the trace elements (Ni, Zn, Fe, Pb, Cd, Co, Cu and Mn) concentrations in the drinking water of Aligarh city and their possible effect on the health of the inhabitants. The higher concen- tration of some elements in the drinking water and the poor health of inhabitants are found correlated. The statistical analysis of the data shows positive correlation between some elements. The principal component analysis of the data gives four factors with significance level of 42%, 29%, 15% and 12% respectively.
