An Analysis of the Marketing Activities of Xiaomi Mobile
(Daffodil International University, 2019-01-12) Saha, Sudipta
This temporary position report depends on my entry level position program as it is required for the BBA program. Xiaomi Corporation in Bangladesh presently comprises the center of the nation's administration data framework.Consumer loyalty's is a standout amongst the most crucial impressions of the movement toward headway and advancement for this organization. The accomplishment of the consumer loyalty's is the key input to enhance benefit quality. The report has composed in three parts.First section including early on part of the report, there I notice principle goal of the report. The fundamental target of the report is to investigate the consumer loyalty's of the Organization as entirety. In setting up this report I utilize both essential and auxiliary information.The second part where I examine subtleties data about Xiaomi versatile and statistical surveying about Xiaomi's. Also, distinguished its action and item class of Xiaomi versatile.The third section manages a few discoveries the issues and give a few proposals to tackled the issues which are drawn by investigation of entire report. At that point I closed my report saying a few proposals and avocations which may assist Xiaomi's with reducing its present issues.
Beryllium sulfide monolayer as a biosensor for early lung disease detection
(Department of Electrical and Electronic Engineering (EEE), BUET, 2025-04-15) Saha, Sudipta; Kawsar Alam, Dr. Md.
Considerable attention has been directed towards the prognosis of lung diseases primarily due to their high prevalence. Despite advancements in detection technologies, current methods such as computed tomography, chest radiographs, bold proteomic patterns, nuclear magnetic resonance, and positron emission tomography still face limitations in detecting diseases related to the lungs. Consequently, there is a need for swift, non-invasive and economically feasible detection methods. Our study explores the interaction between BeS monolayer and breathe biomarkers related to lung disease utilizing the density functional theory (DFT) method. Through comprehensive DFT analysis, including electronic properties analysis, charge transfer evaluations, work function, optical properties assessment and recovery times, the feasibility and efficiency of BeS as a VOC (volatile organic compound) detection are investigated. Findings reveal significant changes in bandgap upon VOC adsorption, with notable alteration in work function for selective compounds. Optical property analyses demonstrate the potential for selective detection of biomarkers within specific wavelength ranges. Moreover, the study evaluates the impact of electric fields and strain on VOC-2D BeS interaction. Furthermore, the desorption of these VOCs from the BeS surface can be achieved through a heating process or under the illumination of UV light. This feature enables the reusability of the 2D material for biosensing applications. These findings highlight the potential of the BeS monolayer as a promising material for the sensitive and selective detection of breath biomarkers related to lung disease.
Extraction of peptides and proteins from senna tora seeds and determination of its antimicrobial activity
(Brac University, 2019-08) Saha, Sudipta; Yasmin, Hasina
Senna tora (L.) Roxb is a plant of Liguminosae family and this family is known to be rich in protein content. The objective of this study is to extract and quantify the amount of peptides and proteins present in Senna tora seeds as well as to analyze its antimicrobial efficacy and these experiments has been done for the first time on Senna tora seeds. To extract the peptides and proteins a cold extraction buffer was used and their presence was determined by SDS-page and its concentration was quantified by Lowry method. Antimicrobial efficacy of the extracted peptides & proteins and methanolic crude extract of the seeds were examined against both gram positive and gram negative bacteria. No antimicrobial activity was found for peptides and proteins but the methanolic crude extract formed clear zone against E.coli and Pseudomonas aeruginosa.
Online Prescription and Drug Management System
(Daffodil International University, 2019-12) Saha, Sudipta; Hossain, Mohammad Nazmul
Our project title is “Online Prescription and Drug Management System” which is a web based application specially for efficient medicine distribution. The modern world is always accelerating forward and looking for various new methods in order to gain access to every form of freedom possible. The greatest form of freedom provided to man in the modern century is through use of the Internet for various tasks. And considering this as a great advantage a large number of people are now moving on to the Internet in order to get medicine or medication. Our aim is to propose a secure and safer Prescribing System that allows prescriptions’ authentication and protects the patient data, keeping their identity confidential.
