Background: The Pakistan Atomic Energy Commission Cancer Registry (PAECCR) program has made availability of a common cancer incidence database possible in Pakistan. The cancer incidence data from nuclear medicine and oncology institutes were gathered and presented. Materials and Methods: The cancer incidence data for the last 30 years (1984-2014) are included to describe a data set of male and female patients. The data analysis concerning occurrence, trends of common cancers in male and female patients, stage-wise distribution, and mortality/follow-up cases is also incorporated for the last 10 years (2004-2014). Results: The total population of provincial capital Lahore is 9,800,000. The total number of cancer cases was 80,390 (males 32,156, females 48,134). The crude incidence rates in PAECCR areas were 580.8/$10^5$ during 2010 to 885.4/$10^5$ in 2014 (males 354.1/$10^5$, females 530.1/$10^5$). The cancer incidence rates for head and neck (15.70%), brain tumors (10.5%), and non-Hodgkin lymphoma (NHL, 9.53%) were found to be the highest in male patients, whereas breast cancer (46.7%), ovary tumors (6.80%), and cervix (6.31%) cancer incidence rates were observed to be the most common in female patients. The age range distribution of diagnosed and treated patients in conjunction with the percentage contribution of cancer patients from 15 different cities of Punjab province treated at the Institute of Nuclear Medicine and Oncology, Lahore are also included. Leukemia was found to be the most common cancer for the age group of 1-12 years. It has been identified that the maximum number of diagnosed cases were found in the age range of 51-60 years for males and 41-50 years for female cancer patients. Conclusions: Overall cancer incidence of the thirty years demonstrated that head and neck and breast cancers in males and in females respectively are the most common cancers in Punjab province in Pakistan, at rates almost the highest in Asia, requiring especial attention. The incidence of brain, NHL, and prostate cancers among males and ovarian and cervix cancers among females have increased rapidly. These data from a major population of Punjab province should be helpful for implementation of appropriate planning, prevention and cancer control measures and for determination of risk factors within the country.
Implementation of User Authentication as a Service for Cloud Network
Masood Shah,Abdul Salam Shah,Imran Ijaz 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.10
There are so many security risks for the users of cloud computing, but still the organizations are switching towards the cloud. The cloud provides data protection and a huge amount of memory usage remotely or virtually. The organization has not adopted the cloud computing completely due to some security issues. The research in cloud computing has more focus on privacy and security in the new categorization attack surface. User authentication is the additional overhead for the companies besides the management of availability of cloud services. This paper is based on the proposed model to provide central authentication technique so that secured access of resources can be provided to users instead of adopting some unordered user authentication techniques. The model is also implemented as a prototype.

Optimal Design Parameters of Stiffeners for Improving Seismic Performance of Links in EBFs
Masood Mojarad,Maryam Daei,Mehrdad Hejazi 한국강구조학회 2020 International Journal of Steel Structures Vol.20 No.5
In eccentrically braced frames (EBFs), the link beam is the main factor determining the behavior of this type of system. In order to enhance the ductility and delaying the web and fl ange buckling, the link beam is reinforced using intermediate web stiff eners to improve its performance and energy dissipation capacity. The web stiff eners spacing criteria is based on short links under pure shear, which have been applied without considering the bending eff ect on intermediate links. In this paper, fi rst the eff ects of stiff ener details and section geometry on the link behavior are investigated using fi nite element modeling, and then by proposing an optimization model, new spacing is proposed for stiff eners of intermediate links that is also consistent with bending distribution, and enhances the performance of intermediate links signifi cantly. To further investigate the results of the optimization model and sensitivity analyses results, the behavior of a total of 52 short, intermediate and long links with diff erent lengths and sections is simulated and investigated under cyclic loading based on ANSI/AISC 341-10 (Seismic provisions for structural steel buildings, Chicago, American Institute of Steel Construction, 2010) using ABAQUS. The results show that the section geometry in W-beams aff ects the stiff eners spacing and thereby, the behavior of intermediate and long links. According to the obtained results in short links, stiff eners spacing are very conservative and can be increased, and for intermediate links, adjusting the stiff eners spacing based on the proposed optimization model can signifi cantly enhance the performance of the link beam.

Improved power conversion efficiency of hybrid solar cells with ITO/ZnO seed layer/ZnO NRs/ZnS QDs/P3HT/PCBM/Ag structure was obtained by optimizing the growth period of ZnO nanorods (NRs). ZnO NRs were grown using a hydrothermal method on ZnO seed layers, while ZnS quantum dots (QDs) (average thickness about 24 nm) were fabricated on the ZnO NRs by the successive ionic layer adsorption and reaction (SILAR) technique. Morphology, crystalline structure and optical absorption of layers were analyzed by a scanning electron microscope (SEM), X-ray diffraction (XRD) and UV-Visible absorption spectra, respectively. The XRD results implied that ZnS QDs were in the cubic phase (sphalerite). Other experimental results showed that the maximum power conversion efficiency of 4.09% was obtained for a device based on ZnO NR10 under an illumination of one Sun (AM 1.5G, 100 mW/cm2).

The aim of present study was to evaluate the stability and toxicity of different doses of liposomal melphalan in rabbit eyes and to investigate the pathological and electrophysiological changes after administration of different doses of free form of melphalan. Liposomes containing melphalan were prepared by solvent evaporation method and mean size of these liposomes and encapsulation efficacy of nanoliposomes were determined. In albino rabbits, intravitreal injections of 10, 20, and 40 lg doses of liposomal melphalan and Alkeran as the commercial product was performed. The rabbits were euthanized at days 2, 7, 14, and 28, and the eyes were enucleated. Vitreous and aqueous samples and electrophysiological recordings were obtained before euthanization. Histological examination was performed after enucleation. Particle size of prepared liposomes was 143.6 ± 3.2 nm. Liposomes have protected melphalan completely from any undesirable release or hydrolysis for 48 h. In a histopathological study, signs of retinal toxicity were found in all doses in the liposomal group at least at one time point during the study. In melphalan injected eyes, histopathological toxicity was found in the 40 lg dose. Extensive variability was found in electrophysiological recordings, and significant waveform changes were found in all injected eyes at least on one occasion during the study. Intraocular administration of liposomal melphalan cannot prolong the drug clearance time of this drug in the vitreous humor. In the 40 lg injected eyes, significant retinal atrophic changes were detected in all eyes throughout the study, and electrophysiological results were consistent with histopathological findings.

In this article, we reported the structural and conductive properties of benzene derivatives/carboxylated zigzag SWCNTs. It was noticed that the carboxylated carbon nanotubes were appropriate adsorbents for benzene derivatives. We presented novel density of states and band structures for modified SWCNTs by both carboxylic group and benzene derivatives. The result showed that nitrobenzene/COOH-SWCNT comprising superb electronic properties can be effectually applied for electronic devices and solar cells, instead of aniline/SWCNT combined system.

Masood Kargar,Mahmood Rabani Bidgoli 국제구조공학회 2018 Steel and Composite Structures, An International J Vol.27 No.4
In this research, vibration and smart control analysis of a concrete foundation reinforced by SiO<sub>2</sub> nanoparticles and covered by piezoelectric layer on soil medium is investigated. The soil medium is simulated with spring constants and the Mori-Tanaka low is used for obtaining the material properties of nano-composite structure and considering agglomeration effects. With considering first order shear deformation theory, the total potential energy of system is calculated and by means of Hamilton.s principle in three displacement directions and electric potential, the six coupled equilibrium equations are obtained. Also, based an analytical method, the frequency of system is calculated. The effects of applied voltage, volume percent and agglomeration of SiO<sub>2</sub> nanoparticles, soil medium and geometrical parameters of structure are shown on the frequency of system. Results show that with applying negative voltage, the frequency of structure is increased.
Bootstrap Correlation Analysis of Function Point Elements
Masood Uzzafer 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.3
This research work investigates the correlation of software function point elements using bootstrap simulation. The correlation of software function point elements plays an important role in understanding the software size; the correlation among function point elements suggests that they measure the same attribute of a software project. Bootstrapping is an effective method to study the statistical properties of correlation coefficients; bootstrap produces a histogram of the possible values of correlation coefficients, which helps to understand the range and spread of the correlation among different function point elements, rater then generating a single point estimate of the correlation.
