Comparison of Blood Pressure in Beta Thalassemia Major Patients with that of Control

Introduction and Objectives : β-thalassemia major patients need to have repeated blood transfusions throughout their life for survival, which leads to so many complications. Heart disease is the most important complication and the main determinant of survival in these patients. Our study shows comparison of blood pressure between these patients and that of normal subjects. Material and Methods : Present study was a cross sectional type of study and consisted of 100 normal subjects (control group) and 100 patients of beta thalassemia major (study group). Blood pressure was recorded in both the groups using mercury sphygmomanometer and statistical analysis of the observations was done using Z test. Results : There was no statistically significant difference in the Systolic blood pressure (SBP) of study group as compared to control group whereas there was a difference in the Diastolic blood pressure (DBP) of study group and control group which was statistically significant (p value <0.0001). Conclusion : There was an overall reduction in the blood pressure of study group as compared to control group but the difference in SBP was statistically not significant whereas that of DBP was statistically significant. Key Words: Beta thalassemia major, Diastolic blood pressure, Systolic blood pressur

Survey of Various Methods used for Speed Calculation of a Vehicle

It is a survey paper of various method used for speed calculation of vehicles. The major purpose of vehicle speed detection is to provide a number of ways that law enforcement agencies can enforce traffic speed laws. The most famous methods include using RADAR (Radio Detection and Ranging) and LIDAR (Light Detection and Ranging) devices to detect the speed of a vehicle. RADAR use microwaves pules and LIDAR use coherent light beam for speed calculation. The SDCS (Speed Detection Camera System) and SMBI (Single Motion Blurred Image) method are also use on high traffic area to measure speed of vehicle using video stream and single image captured by stationary camera.

VUV PROPERTIES OF Eu3+- DOPED YBO3 PHOSPHOR PREPARED VIA ALDO-KETO AND SOLID-STATE PROCESS

The Eu3+ doped YBO3 was prepared by the novel aldo-keto method. The structure and VUV luminescence properties of the title compound were studied and compared to the corresponding properties of the materials prepared by a conventional solid state reaction. The use of novel aldo-keto method in preparation lowered the reaction threshold temperature by c.a. 300oC. The YBO3 phosphor from the aldo-keto method look like evenly sized spherical structures, whereas those from the solid-state process look like some agglomerates of little spheres. The Eu3+-doped YBO3 phosphors prepared by both methods showed the red emission with peak around 592, 611 and 627 nm at excitations wavelengths 147 and172 nm, which corresponds to the transitions from the excited 5D0 level to the 7FJ (J = 1, 2, 3, 4) levels of Eu3+ activators. However, the emission intensity of the Eu3+ doped YBO3 from the aldo-keto system is about 2 times as much as that from the sold-state process

EVALUATION OF BIOLOGICAL ACTIVITIES OF NANOCRYSTALLINE TETRAGONAL ZIRCONIA SYNTHESIZED VIA SOL-GEL METHOD

Objective: The objective of the following study was a synthesis of nanocrystalline tetragonal zirconia (ZrO2) using simple sol–gel method and evaluation of its structural and biological properties.Methods: The sample was characterized by X-ray powder diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Transmission Electron Microscopy (TEM) and evaluated for cell growth study using 3T3 mouse fibroblast cells and for degradation using Phosphate Buffered Saline (PBS) solution. The synthesized materials were also evaluated for their antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) bacterial strains.Results: The XRD pattern shows that the tetragonal phase of nanocrystalline zirconia was obtained at relatively low temperature i.e. 300 °C. The FESEM images showed that the prepared sample consists of particles in the range of 35-69 nm and homogenous particle size distribution. The TEM images confirmed the results shown by FESEM images. The sample of zirconia has excellent tissue biocompatibility, higher cell growth and does not show the toxicity towards normal 3T3 mouse fibroblast cells. The result of qualitative antibacterial tests revealed that the nanocrystalline zirconia had an important inhibitory activity on E. coli and S. aureus. The sample shows stability at the physiological condition and does not show degradation.Conclusion: Nanocrystalline tetragonal zirconia shows higher cell growth and efficient antibacterial activity against E. coli and S. aureus bacterial pathogen and also it is stable at the physiological condition. Hence, it can be used for various biomedical applications.Keywords: Nanocrystalline zirconia, Sol-gel route, Antimicrobial action, Biomedical applicatio

On Protection by Layout Randomization

Layout randomization is a powerful, popular technique for software protection. We present it and study it in programming-language terms. More specifically, we consider layout randomization as part of an implementation for a high-level programming language; the implementation translates this language to a lower-level language in which memory addresses are numbers. We analyze this implementation, by relating low-level attacks against the implementation to contexts in th

Individual rules for trail pattern formation in Argentine ants (Linepithema humile)

We studied the formation of trail patterns by Argentine ants exploring an empty arena. Using a novel imaging and analysis technique we estimated pheromone concentrations at all spatial positions in the experimental arena and at different times. Then we derived the response function of individual ants to pheromone concentrations by looking at correlations between concentrations and changes in speed or direction of the ants. Ants were found to turn in response to local pheromone concentrations, while their speed was largely unaffected by these concentrations. Ants did not integrate pheromone concentrations over time, with the concentration of pheromone in a 1 cm radius in front of the ant determining the turning angle. The response to pheromone was found to follow a Weber's Law, such that the difference between quantities of pheromone on the two sides of the ant divided by their sum determines the magnitude of the turning angle. This proportional response is in apparent contradiction with the well-established non-linear choice function used in the literature to model the results of binary bridge experiments in ant colonies (Deneubourg et al. 1990). However, agent based simulations implementing the Weber's Law response function led to the formation of trails and reproduced results reported in the literature. We show analytically that a sigmoidal response, analogous to that in the classical Deneubourg model for collective decision making, can be derived from the individual Weber-type response to pheromone concentrations that we have established in our experiments when directional noise around the preferred direction of movement of the ants is assumed.Comment: final version, 9 figures, submitted to Plos Computational Biology (accepted
