Henry P. Kendall
Henry Plimpton Kendall (January 15, 1878 – November 3, 1959) was a New England entrepreneur, industrialist, and philanthropist from Walpole, Massachusetts. He is considered one of the pioneers of scientific management.[1] Kendall was born in 1878 in Charlestown, Massachusetts, son of Henry Lucien Kendall en Clara Idella (Plimpton) Kendal. After attending the Lawrenceville School, boarding

SERS for the Detection of Foodborne Pathogenic Bacteria
Detection of foodborne pathogens at an early stage is very important to control food quality and improve medical response. Rapid detection of foodborne pathogens with high sensitivity and specificity is becoming an urgent requirement in health safety, medical diagnostics, environmental safety, and controlling food quality. Surface-enhanced Raman spectroscopy (SERS) is a real-time detection method that depends on the inelastic scattering of excitation light and molecular resonance, and has been applied to different applications for detecting and classifying various pathogens.

Basic Principles of Atomic Force Microscopy
Visualization of biomedical samples in their native environments at the microscopic scale is crucial for studying fundamental principles and discovering biomedical systems with complex interaction. The study of dynamic biological processes requires a microscope system with multiple modalities, high spatial/temporal resolution, large imaging ranges, versatile imaging environments and ideally in-situ manipulation capabilities. Development of new Atomic Force Microscopy (AFM) capabilities has made it such a powerful tool for biological and biomedical research.

Main Technological Challenges in Implementing Holographic-Type Communication
Holographic-type communication (HTC) permits new levels of engagement between remote users. It is anticipated that it will give a very immersive experience while enhancing the sense of spatial co-presence. In addition to the newly revealed advantages, however, stringent system requirements are imposed, such as multi-sensory and multi-dimensional data capture and reproduction, ultra-lightweight processing, ultra-low-latency transmission, realistic avatar embodiment conveying gestures and facial expressions, support for an arbitrary number of participants, etc.

Direct and Indirect Solar Gain Systems
The energy crisis, the risk of interruptions or irregular supplies of conventional energy carriers, and the need to protect the environment stimulate the search for new solutions to improve the heat balance of buildings with the use of solar energy. Based on the criterion of the storage, distribution, and discharge time of stored heat, passive solar gain solutions can be divided into direct and indirect solar gain systems.

Microfluidic Devices for HIV Diagnosis at Point-of-Care Settings
Human immunodeficiency virus (HIV) is a global epidemic; however, many individuals are able to obtain treatment and manage their condition. Progression to acquired immunodeficiency syndrome (AIDS) occurs during late-stage HIV infection, which compromises the immune system, making it susceptible to infections. While there is no cure, antiretroviral therapy can be used provided that detection occurs, preferably during the early phase. However, the detection of HIV is expensive and resource-intensive when tested with conventional methods, such as flow cytometry, polymerase chain reaction (PCR), or enzyme-linked immunosorbent assays (ELISA). Improving disease detection in resource-constrained areas requires equipment that is affordable, portable, and can deliver rapid results. Microfluidic devices have transformed many benchtop techniques to on-chip detection for portable and rapid point-of-care (POC) testing. These devices are cost-effective, sensitive, and rapid and can be used in areas lacking resources. Moreover, their functionality can rival their benchtop counterparts, making them efficient for disease detection.

Sinking of the Dalniy Vostok
The Russia n-flagged fishing trawler Dalniy Vostok (Russian: «Дальний Восток» [ˈdalʲnʲɪj vɐsˈtok]; “Far East”) sank on 1 April 2015, off Russia’s Kamchatka Peninsula in the Sea of Okhotsk. Fifty-seven of the ship’s 132 crew members were confirmed dead, with rescue operations underway for survivors. The freezer trawler sank 183 nautical miles (330 kilometers) west of Krutogorovsky, a settlement in Kamchatka’s Sobolevsky District. Sixty-three crew members were rescued by other fishing vessels, and 12 remain missing. Although recovery efforts continued on April 3, the TASS news agency reported that it was believed that the missing drowned in the engine room, and that all survivors had been rescued.

Buck-Boost DC-DC Converters for Fuel Cell Applications
The use of fuel cells in DC microgrids has been receiving a lot of attention from researchers and industry since both technologies can deliver clean energy with little to no environmental impact. To effectively integrate fuel cells in DC microgrids, a power converter that can equate the fuel cell’s voltage with the DC microgrid’s reference voltage is required. Based on the typical output voltages of fuel cells, buck-boost topologies are commonly used in this type of application. This work compiles, compares and describes different DC-DC buck-boost topologies that have been introduced in the literature over the past few years.
