Research ArticleOpen accessIn the abstractCorrelation of Some Tumor Markers Between Serum and Saliva of Patients with Breast CancerHuthaifa Tarawneh, Omar AtroozBreast cancer, which affects 36% of all female oncological patients, is the most frequent cancer in the world among women. Since routine laboratory evaluation of serum can be stressful for patients, it is critical to comprehend the features and limitations of salivary test methods in order to achieve an accurate diagnosis of breast cancer. The purpose of the study is … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 12 Oct 2024 · 4,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Synthesis of a Classic, Manual GearboxRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuToday, various types of gearboxes have been introduced into the vehicles to change the way the classic manual gearboxes work, such as automatic gearboxes, semi-automatic, continuous variable, dual-clutch automatic gearboxes etc. However, most gear shifters for in-service vehicles are still classical manuals, which is why their optimal synthesis based on their dynamics and especially on optimal performance is now more … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 30 Apr 2018 · 8,642 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Simulation and Optimum Operation Strategy of a Trigeneration System Serving a HospitalFrancesco Calise, Massimo Dentice d'Accadia, Luigi Libertini et al.This paper presents a numerical analysis of a trigeneration system in a hospital, aiming at determining the cost-optimal operating strategy as a function of the energy demands to be matched. The system includes: A natural gas fired reciprocating engine, heat exchangers for waste-heat recovery, a single-stage LiBr-H2O Absorption Chiller (ACH), a cooling tower, pumps, a backup boiler, a backup vapour-compression … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 29 Aug 2016 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractDo Firm Size and Financial Performance Affect Corporate Social Responsibility Disclosure: Employees' and Environmental Dimensions?Mohammad Ebrahim NawaisehThe paper empirically tests the impact of company size and financial performance on Corporate Social Responsibility Disclosure (CSRD), from the Employees' and Environmental Dimensions perspective with reference to the disclosure frequency and quality of these dimensions among Jordanian industrial public share holding companies; whether there is an impact of firm size measured by total assets, ROA, ROE and Leverage on … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 29 Nov 2015 · 8,329 accessesView PDFCite
Research ArticleOpen accessIn the abstractDYNAMIC MODELING AND GAIN SCHEDULING CONTROL OF A CHIILLED WATER COOLING SYSTEMJun Liu, M. ZaheeruddinA dynamic model of a Chilled Water (ChW) cooling system with a stratified ChW tank was developed. A PI-based Gain Scheduling (GS) control strategy was designed to improve thermal performance of the chiller system. Five different operation strategies were simulated and the energy consumption and cost of operating the system under full load and partial load conditions were compared. The … …Energy Research Journal, Vol. 5, Issue 1 · 15 Oct 2014 · 7,015 accessesView PDFCite
Research ArticleOpen accessIn the abstractWINDOWS WEB PROXY CACHING SIMULATION: A TOOL FOR SIMULATING WEB PROXY CACHING UNDER WINDOWS OPERATING SYSTEMSWaheed Yasin, Hamidah Ibrahim, Nur Izura Udzir, Nor Asilah Wati Abdul HamidWeb caching plays a key role in improving the performance of the web by reducing the latency of delivering web objects to the users. On the other hand, a simulation tool plays a key role in studying the behavior of any network such as studying the effects of web caching on the performance of the network. The aim of this … …Journal of Computer Science, Vol. 10, Issue 8 · 7 Mar 2014 · 10,978 accessesView PDFCite
Research ArticleOpen accessIn the abstractSECURITY BREACH IN TRADING SYSTEM-COUNTERMEASURE USING IPTRACEBACKM. P. Rajakumar, V. ShanthiRecently, economic scenario is often facing security breach that has heavy impact on the financial soundness of a company particularly, stock prices on firms.
