Performance Analysis Of Iot-Based Healthcare Heterogeneous Delay-Sensitive Multi-Server Priority Queuing System, Barbara Kabwiga Asingwire, Alexander Ngenzi, Louis Sibomana, Charles Kabiri

All Rsif Scholars' Publications

Previous studies have considered scheduling schemes for Internet of Things (IoT)-based healthcare systems like First Come First Served (FCFS), and Shortest Job First (SJF). However, these scheduling schemes have limitations that range from large requests starving short requests, process starvation that results in long time to complete if short processes are continuously added, and performing poorly under overloaded conditions. To address the mentioned challenges, this paper proposes an analytical model of a prioritized scheme that provides service differentiation in terms of delay sensitive packets receiving service before delay tolerant packets and also in terms of packet size with the short …

Nanobodies: Their Potential For Applications In Biotechnology, Diagnosis And Antiviral Properties In Africa; Focus On Application In Agriculture, Faith Njeri Njeru, Paul Mbogo Kusolwab

All Rsif Scholars' Publications

Antibodies are key elements in routine immunological tests, having a long history in detection of plant pathogens due to their specificity, reliability and fast performance. Heavy chain-only antibodies (HCAbs), circulating in the blood of camels are IgG isotypes that lack the light (L) chains and the heavy (H) chain is depleted of the first constant domain (CH1). The HCAbs interact with the antigen by virtue of only one single variable domain, referred to as VHH or nanobody (Nb). Owing to their unique properties: nanometer scale size, robust structure, stable and soluble behaviour in aqueous solution, high affinity and specificity for …

Drunk Drivers Are A Moving Time Bomb: Should States Impose Liability On Both Social Hosts And Commercial Establishments Whose Intoxicated Guests And Patrons Subsequently Cause Injuries Or Death To Innocent Third Parties, Tracey B. Carter

Law Faculty Scholarship

This Article examines whether states should impose civil liability not only on commercial alcohol vendors under dram shop statutes, but also on social hosts whose intoxicated guests subsequently cause injury or death to innocent third parties. Drawing upon national drunk-driving statistics, historical development of dram shop laws, and comparative analysis of state approaches—particularly in Southeastern jurisdictions—the Article evaluates the effectiveness and limitations of existing liability frameworks. While most states recognize statutory liability for commercial establishments that serve visibly intoxicated persons or minors, many decline to extend comparable liability to social hosts serving adult guests. The Article analyzes the policy arguments …
