Background: Goiter is defined as an enlargement of the thyroid gland and it had been recognized since 2700B.C. Thyroid cancer is responsible for six deaths per million persons annually. Most patients present with a palpable swelling in the neck. The finding of a clinically solitary non toxic thyroid nodule has usually being a strong indication for surgery because it is considered to be a highly suspicious sign of carcinoma. Aim of study: To evaluate the role and accuracy of history taking, physical examination and FNAC in the pre-operative diagnosis of thyroid cancer.

Background and aims: Recent estimations show us an important increase of the neoplastic disorders, especially in developed countries, cancer being the second cause of mortality after cardiovascular diseases. Diabetes mellitus type 2 is associated with an increased risk of neoplastic diseases (especially colorectal cancer, breast cancer, pancreatic cancer). The factors involved in the increase of this risk at patient with diabetes mellitus type 2 are hyperglycemia, hyperinsulinemia and high levels of the hormone insulin-like growth factor 1 (IGF-1).

In this paper, we utilize the CLRS and JCLRST properties to prove some existence theorems of common fixed point for contractive mappings in fuzzy metric spaces. Our results generalize and extend the result of Saurabh Manror and Calogero vetro [28]. An example and some applications are given to show the usability of the presented results.

The role of industry in general and mainly processing industry in maintaining economic growth is placed under the thorough point of view in this paper. Brief review of concerned literature is performed as well. Trigonometric function has been applied in measuring the structural changes in industrial sector. Practical unit of the paper deals with structural changes estimating of the structure of industry sector of Uzbekistan. Econometric analysis of industry output influence on gross domestic product has been conducted and final conclusions have been worked out in the paper.

Airplane exhaust and rocket fuel at high altitudes add small quantities of air pollutants and haze from partly combusted fuel. The high altitude haze is long-lived, regional, and transported by jet streams. The high altitude haze life-time (half-life probability) is greater than at the ground. The data on carbon dioxide emissions from international travel and Southern Asiatic mountain shields may be representative of the haze. Also, any air pollutant heavier than the ambient air exerts signature physical properties.

This paper investigates professionalism in mathematics teacher education and its influence on teacher practice in Liberia with special reference to the KRTTI and ZRTTI. In the study, we used samplesize of 100 teachers and 23 administrators. We employed a combination of both quantitative and qualitative research methods. The quantitative approach used was a self-administered questionnaire and the qualitative approaches included use of interviews and an observation guide. The study reveals the following findings: a teacher’s professional education does affect his/her practices on the job.

Energy is vital for sustaining life on earth. The scope of this paper is to study the working, sizing, optimization and control of solar-wind hybrid systems. A brief introduction to the optimization software tools namely Homer is also included. A virtual case study for designing a solar-wind hybrid system is considered. The results along with cost analysis are also presented. The case study verifies that solar-wind hybrid systems can prove to be a better option to replace the conventional sources of energy.

This paper presents a real-time driver drowsiness detection system for driving safety. Based on computer vision techniques , the driver’s face is located from a color video captured in a car. Then, face detection is employed to locate the regions of the driver’s eyes, which are used as the templates for eye tracking in subsequent frames. Finally, the tracked eye’s images are used for drowsiness detection in order to generate warning alarms. The proposed approach has three phases: Face, Eye detection and drowsiness detection.

Images of high (or) super resolution will be good to see. And having excellent clarity in all kinds of devices. Nowadays all mobile displays are not providing the users expecting clarity. Snaps taken from the mobile will be blurred (or) not clear sometimes. Reason for these problems are not using clarity lenses, shaking of mobile while taking snaps. For getting clarity in images first we should consider the pixels of the images. Pixels of an image should be very minute. If the image having very less spilt up in their pixels, then that image will look like blurred.

The aim of the present investigation is to study the peristaltic transport through the gap between coaxial tubes, where the inner tube is an endoscope and the outer tube has a sinusoidal wave travelling down to its wall. The necessary theoretical results such as viscosity, pressure gradient and friction force on the inner and outer tubes have been obtained in terms of magnetic field. Out of these theoretical results the numerical solution of pressure gradient, outer friction, inert friction and flow rate are shown graphically for the better understanding of the problem.
