Quality of Life after Functional Endoscopic Sinus Surgery in Patients with Chronic Rhinosinusitis  [PDF]
Sadaf Qadeer, Shabbir Akhtar, Montasir Junaid, Muhammad Sohail Halim
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2018, DOI: 10.4236/ijohns.2018.74020
Abstract: Chronic Rhinosinusitis (CRS) is a group of disorders characterized by the inflammation of mucosa of the nasal passages and paranasal sinuses. It includes chronic rhinosinusitis with polyps, CRS without polyps and Allergic Fungal Sinusitis (AFS). This debilitating disease causes negative impact on quality of life (QOL) of patients. Functional endoscopic sinus surgery (FESS) is the mainstay of surgical treatment for patients and improves QOL of patients. This subjective assessment of QOL can be measured by disease specific questionnaires. SNOT-22 questionnaire is widely used and validated questionnaire for this purpose. Prospective study was done on 54 patients. Data were collected using SNOT-22 questionnaire and filled in pre-operative period then in post-operative follow-up visits on 1st, 3rd, 6th and 12th months. Paired sample t-test was used to compare pre-operative and post-operative SNOT scores and multivariate generalized linear model was used to estimate regression parameters for SNOT scores in CRS with polyp and AFS in comparison of CRS without polyps. Out of 54 patients, 59.3% were males, mean age was 35.98, 29.6% were in CRS without polyp group, 44.4% and 25.9% were in CRS with polyps and AFS group. Recurrence occurred in 7.4%, revision surgery required in 3.7% while 22.2% had history of asthma. Paired sample t-test showed statistical significant reduction in post-operative SNOT scores. Linear model results showed SNOT scores in CRS with polyp group was significantly reduced. Thus FESS provides significant improvement in QOL of patients in chronic rhinosinusitis.

Abstract: This study pertains to the evaluation of shale gas and rock physics properties of this area with respect to its total organic content of Sember Formation, Khiproarea, Pakistan. We use well logs data for this study. The Khipro area is prominent in the Lower Indus Basin for its hydrocarbon (oil and gas) structural traps. In shale gas evaluation, TOC of Sember Formation is estimated. The analysis has been done with the help of the wire line data of the well Bilal North-01. The presence of shale gas in the study area is analyzed with the help of different techniques. Rock physics and petrophysical analysis have been done in order to get the properties of the area related to the shale gas evaluation.
Efficient Energy Performance within Smart Grid  [PDF]
Khizer Ayaz, Muhammad Sohail Sulemani, Naseer Ahmed
Smart Grid and Renewable Energy (SGRE) , 2017, DOI: 10.4236/sgre.2017.83005
Abstract: The Smart Grid, regarded as the next generation power grid, uses two-way flows of electricity and information to create a widely distributed automated energy delivery network. Energy/power plays a critical role for social, economic and industrial development. Because of industrial generalization, especially in agricultural and economical activities, the energy demand has increased rapidly in developed countries. Generation and usage of energy has direct impact on modern power grid. In this scenario energy management is a hard task because load is dynamic and we don’t have control over it. Renewable or undepleted energy resources have great applications and impact in current electric power system situation. For example it gives pollution free (green) energy which is environment and user friendly. It is cost effective; it uses natural resources for its generation and hence do not waste any coal, gas etc. There are many inducements to empower energy productivity. As current smart grid is complex and non linear in operation and design, it used an optimized method that provides maximum efficiency with minimum input. Our work depicts a case study of hybrid electric aircraft for achieving high performance.
Moderate Interpretation with Attribute Analysis and 3d Visualization for Deeper Prospects of Balkassar Field, Central Potwar, Upper Indus Basin, Pakistan  [PDF]
Farhana Masood, Zulfiqar Ahmad, Muhammad Sohail Khan
International Journal of Geosciences (IJG) , 2017, DOI: 10.4236/ijg.2017.85037
Abstract: Balkassar is an old field with considerable remaining potential. The 2d, 3d seismic and earlier vintages show that Balkassar is composed of two folds that impart heart shaped geometry. It appears likely the early Eocene age Bhadrar formation may provide commercial production with lower water cuts from the eastern lobe (yet untapped) of the structure that may have at least 30 million barrels of unrecovered oil. Horizontal drilling may have promise as an optimum technique for recovery of oil from Paleogene reservoirs. Encouraging oil indications have also been recorded from the early Permian age tobra formation from Balkassar oxy-1 that was not tested by Oxy. Tobra sandstone reservoir can have a matrix porosity approaching 8%. When fractured recoveries from it can be relatively better than the Paleogene reservoirs. The 2D and 3D seismic acquisition has confirmed that the eastern lobe (yet untapped) of the Balkassar field is structurally higher and steeper than the Western lobe which has thus far produced over 30 million barrels. The Eastern lobe thus offers good potential for recovery of oil from the Bhadrar reservoir. The entire field is likely to have potential for recovery of oil from the early Eocene aged Tobra formation. 2-d and 3-D Seismic data interpretation, attribute analysis and visualization for deeper prospect carried in Balksasar field. Tobra and Khewra formation studied for deeper potential drilling. Time contour and depth contour map shows potential for deeper prospects. Also attribute analysis and 3d visualization show good results for deeper potential of Tobra and Khewar formations. Seismic amplitude, Reflection strength, Apparent polarity attribute are visualized and interpreted to find the potential for Tobra and Khewra formation. 3-D visualization also showed positive results for Tobra and Khewra formations.

Assessment of Rock Mass Quality and Deformation Modulus by Empirical Methods along Kandiah River, KPK, Pakistan  [PDF]
Mian Sohail Akram, Kamran Mirza, Muhammad Zeeshan, Muhammad Asad Jabbar
Open Journal of Geology (OJG) , 2018, DOI: 10.4236/ojg.2018.810057
Abstract: The pivotal aim of this study is to evaluate the rock mass characterization and deformation modulus. It is vital for rock mass classification to investigate important parameters of discontinuities. Therefore, Rock Mass Rating (RMR) and Tunneling quality index (Q) classification systems are applied to analyze 22 segments along proposed tunnel routes for hydropower in Kandiah valley, Khyber Pakhtunkhwa, Pakistan. RMR revealed the range of fair to good quality rocks, whereas Q yielded poor to fair quality rocks for investigated segments of the rock mass. Besides, Em values were acquired by empirical equations and computer-aided program RocLab, and both methods presented almost similar variation trend of their results. Hence, the correlations of Em with Q and RMR were carried out with higher values of the regression coefficient. This study has scientific significance to initially understand the rock mass conditions of Kandiah valley.
Knowledge Discovery in Endangered Species Diversification
Muhammad Naeem,Sohail Asghar
International Journal of Information Technology and Computer Science , 2013,
Abstract: Classification of regional territories and countries related to endangered species has been investigated by data mining techniques and graphical modeling using an extensive data set of species. We developed the graphical models (hereafter referred to as ‘ESDI’) using cosine, jaccard similarity, K Mean clustering and cliques in graph modeling for a large number of countries. Environmental variables associated with species records were identified in context of their diversification to integration with our proposed prototype. We have shown that the problem of finding the most coherent clusters is reducible to finding maximum clique. Key findings include the urge to ameliorate communication about the loss and protection of endangered species and their concerned projects. The proposed framework is presented to serves a portal to knowledge discovery. We have concluded that the proposed framework model and its associated data mining similarity measures can be useful for investigating various scientific and management oriented questions related to protection of endangered species with emphasis on collaboration among regional countries. The rationale behind the proposed approach is that the countries which have been grouped into same clique inherit a lot of argues illustrating common reasons of their struggles towards ecological safety with minimization of perils for endangered species. The development and implementation of a regional approach based on this similar grouping address the actions that could offer significant benefits in achieving their goal for ecological policies. Other critical actions at this clique level include fortifying and elevating harmonization of legal frameworks with emphasis on prevention procedural issues; awareness realizations of endangered species issues and its priority. Such actions will eventually lead towards implementation of essential plans fulfilling co-operative expertise and common endeavors.
An Architecture for Integrated Online Analytical Mining
Muhammad Usman,Sohail Asghar
Journal of Emerging Technologies in Web Intelligence , 2011, DOI: 10.4304/jetwi.3.2.74-99
Abstract: Several works in the past proved the likelihood and interest of integrating Online Analytical Processing (OLAP) with data mining and as a result a new promising direction of Online Analytical Mining (OLAM) has emerged. In this paper, a variety of OLAM architectures in the literature were reviewed and the limitations in the previously reported work have been identified. Literature review reveals the fact that none of the previously reported OLAM architectures have integrated enhanced OLAP with data mining. This work is an attempt to enhance OLAP performance in terms of cube construction time and to improve visualization by providing interactive visual exploration of the data cube. The main aim of this paper is to propose an integrated OLAM architecture that not only overcomes the existing limitations but also extends the architecture by adding an automation layer for the schema generation. In the proposed work, hierarchical clustering has been used as the data mining technique and three types of warehouse schemas namely were automatically generated. A prototype of automatic schema generation has been developed and schema generation algorithms have been provided. In addition to this, we implemented and deployed the proposed architecture. Validation has been done by performing experiments on real life data set. Experimental results prove that the proposed architecture improves the cube construction time, empowers interactive data visualization, automate schema generation, and enable targeted analysis at the front-end. With this seamless integration a higher degree of improvement is achieved which makes significant advancement in the modern OLAM architectures.

The Professional Medical Journal , 2001,
Abstract: OBJECTIVES: a). To evaluate the etiological factors of epistaxis. b). To evaluate theimportance of nasal examination in the diagnosis. c). To compare the efficacy of varioustreatment methods. DESIGN: Prospective study. SETTING: Department of Otolaryngologyand Head Neck Surgery Nishtar Hospital Multan and Aga Khan University Hospital Karachi.MATERIALS & METHODS The study consists of a prospective evaluation of 100 patients presentingwith nasal bleeding and requiring admission. All the patients were thoroughly evaluated with a detailedhistory, physical examination, systemic examination and ENT examination and a same set of investigationswere done in all the patients. RESULTS: In our series inflammatory affections of nose and sinuses andtrauma to nose are commonest etiologies of pediatric epistaxis. Among the treatment modalitiescauterization was only effective when a bleeding point can be identified and was accessible. Comparisonof various packing materials showed Vaseline gauze to be most useful and cost effective. Submucousresection was effective in controlling bleeding after failure of nasal packing but arterial ligation was lastresort if bleeding could not be controlled with anterior and posterior nasal packing. CONCLUSIONS:Inflammation of the nose and sinuses and trauma to nose is commonest etiological factors in pediatricepistaxis. Chemical cautery is as effective as electric cautery in control of simple epistaxis where bleedingpoint can be identified. Vaseline gauze should be used for anterior nasal packing being efficacious as wellas cost effective. Submucous resection may be considered as effective step if packing fails to controlbleeding before proceeding for arterial ligation.
