Short-Term Fatigue Damage Of Tethers Of Long-Span Floating Cable Supported Bridges Under Harsh Waves, Deokhee Won, Keesei Lee, Young-Jong Kang, Seungjun Kim

Journal of Marine Science and Technology–Taiwan

A floating bridge can be effectively used for sea-crossing in deep water. Because the superstructure of the bridge is supported by floating substructures with pontoons, the conventional fixed piers, towers, foundations, and piles are not required. Instead, a rational mooring system can be used to strictly maintain the target position of the floating substructures against environmental loads, including winds, waves, and currents. Recently, long-span cable-supported bridges with floating towers were investigated and found to overcome the limitations of conventional cable-supported bridges, when used as sea-crossing infrastructure. To design the moorings for very large floating structures, the structural safety should be …

Physics: Faculty Publications

Quantum fluctuations in the effective spin-1/2 layered structure triangular-lattice quantum Heisenberg antiferromagnet Ba₃CoSb₂O₉ lift the classical degeneracy of the antiferromagnetic ground state in magnetic field, producing a series of novel spin structures for magnetic fields applied within the crystallographic ab plane, including a celebrated collinear ‘up-up-down’ spin ordering with magnetization equal to 1/3 of the saturation magnetization over an extended field range. Theoretically unresolved, however, are the effects of interlayer antferromagnetic coupling and transverse magnetic fields on the ground states of this system. Additional magnetic-field-induced phase transitions are theoretically expected and in some cases have …

Dynamic Behavior Of A Long-Span Cable-Stayed Bridge With Floating Towers After The Sudden Failure Of Tethers And Cables Under Irregular Waves, Minseo Jang, Yunwoo Lee, Seungjun Kim, Young-Jong Kang

Journal of Marine Science and Technology–Taiwan

Cable-supported bridges with floating towers do not require fixed piers at the seabed. Therefore, innovative conceptual models have been continuously developed to overcome the limitations of conventional bridges in deep waters. The main floating tower that supports superstructures using stay cables is balanced by the buoyancy of floaters moored by tethers. The applicability of floating bridges should be verified by evaluating the overall stability considering the tether design. Here, various cases of the sudden failure of tethers and stay cables under the environmental conditions of a 100-year return period are simulated in a time-domain. The floating cable-stayed bridges are subjected …

Sea Level Rise In Indonesia: The Drivers And The Combined Impacts From Land Subsidence, Triana Karlina, Wahyudi A'An Johan

ASEAN Journal on Science and Technology for Development

Sea level changes play an important role as an indicator of climate change. However, without climate change, the sea level itself shows strong regional patterns, both in space and time, that could deviate significantly from global averages. The spatial variability of sea level changes in Indonesia can be divided based on its drivers, i.e., climatic and seasonal weather-driven and non-climatic and geological-driven. Seasonally, the sea level in Indonesia is generally high in northwest monsoon and low in southeast monsoon. Nevertheless, there is a possibility of extreme natural phenomenon influences that generate anomalies and a thermosteric process that also affects the …

ASEAN Journal on Science and Technology for Development

The emission of greenhouse gases, including high CO2 and other materials, initiates global warming and climate change. Atmospheric CO2 that affects the carbonate system of seawater causes ocean acidification (OA). OA affects marine organisms directly, as well as humans economically and ecologically. Considering the high impact of OA and following the United Nations' Sustainable Development Goals, systematic research and monitoring of OA is necessary in Indonesia, whose seas play an important role in this emerging phenomenon. This review discusses the urgency of OA monitoring systems and suggests carbonate system monitoring, as well as carbon biogeochemistry. OA significantly affects marine production …

The Long Shadow Of Jacobson V. Massachusetts: Public Health, Fundamental Rights, And The Courts, Daniel Farber

San Diego Law Review

The COVID-19 pandemic struck the United States in early 2020. The coronavirus prompted public health mandates without precedent for at least a century. Some states almost entirely locked down. These measures inevitably impinged on activities that the Constitution would normally protect. In confronting these cases, many courts have turned to a 1905 Supreme Court case decision, Jacobson v. Massachusetts, often considered the leading case in public health law. There is little agreement, however, about how that decision fits into the current framework of constitutional law. As a result, courts have differed widely in the degree of deference they give …

We Are All Gig Workers Now: Online Platforms, Freelancers & The Battles Over Employment Status & Rights During The Covid-19 Pandemic, Orly Lobel

San Diego Law Review

Since the early days of the Coronavirus pandemic, unemployment rates leapt to the highest they have been since 1975. Congress passed the Coronavirus Aid, Relief, and Economic Security (CARES) Act in March 2020, a $2 trillion relief package, offering augmented unemployment relief not only to employees but also to the self-employed, including gig workers. The Families First Coronavirus Response Act (FFCRA) was passed to provide sick leave in the form of tax credits that also extended to the self-employed. Beyond the governmental responses, platform companies offered new limited relief to their workers in the form of sick leave, even as …

Covid-19 And Preventing Harm To Vulnerable Children, Jessica K. Heldman, Margaret A. Dalton, Robert C. Fellmeth

San Diego Law Review

Although COVID-19 mercifully seems to affect children less severely than adults, children are far from immune from the impacts of the virus. Public health orders closing schools and businesses, cancelling events, and keeping children at home have been disruptive and distressing to many children and families. But for children who rely on government entities for protection, care, custody, and services, the effects of the public health orders can be devastating. COVID-19 and the response to it has serious implications for the safety, well-being, and development of these vulnerable children—those within the child welfare, juvenile justice, and special education systems. All …

More Than A Mask: Stay-At-Home Orders And Religious Freedom, Dorit Rubinstein Reiss, Madeline Thomas

San Diego Law Review

COVID-19 has changed our legal universe. Many states are responding by issuing stay-at-home orders, and as cases rise, may have to prohibit gatherings again. One issue states and courts have to grapple with is the relationship between stay-at-home orders and religion. Stay-at-home orders that require closing down churches may be challenged as violating the First Amendment’s guarantee of religious freedom. Under our current jurisprudence, these cases may be handled under a highly deferential standard or under strict scrutiny—depending on the specific order in question, as well as on whether the state has a Religious Freedom Restoration Act (RFRA). We recommend, …

Crisis Standards Of Care And State Liability Shields, Valerie Gutmann Koch

San Diego Law Review

The COVID-19 pandemic has overwhelmed many U.S. systems—including the already-strained medical system—intended to protect and care for its citizens. In the United States, New York became the first epicenter of the pandemic, accounting for approximately five percent of global COVID-19 cases by March 2020. Hospitals, health care providers, and policymakers soon recognized that, in New York and beyond, they faced a bleak reality that—if the spread of the virus could not be controlled—there would soon not be enough ventilators for all patients who needed them, despite hospitals practicing “surge capacity” to reduce the need for ventilators by canceling or postponing …

The Covid Cases: A Preliminary Assessment Of Judicial Review Of Public Health Powers During A Partisan And Polarized Pandemic, Wendy E. Parmet

San Diego Law Review

In response to the very real possibility that there will be insufficient resources to properly respond to the COVID-19 pandemic, states have been developing crisis standard of care plans, which may authorize the prioritization of patients for scarce resources based on changing circumstances and increased demands. Due to the dearth of necessary resources and trained professionals during a public health emergency, the standard of care that clinicians may be able to provide during the COVID-19 pandemic may, by necessity, depart significantly from standard nonemergency medical practice. Adhering to crisis standards of care may expose health care providers and entities to …

Prisons And Pandemics, Camila Strassle, Benjamin E. Berkman

San Diego Law Review

This Article focuses on how to balance public health, public safety, and incarcerated people’s legal rights when implementing a program for early release from confinement. Ethical, epidemiological, and legal arguments all point to a need for an immediate reduction in the incarcerated population. However, this leaves open several points of reasonable disagreement about how to manage early release. These include how to set priorities for processing and releasing individuals across the country. For example, officials could prioritize screening individuals who are housed in facilities that have been hit hard by infection; or by screening individuals who have a safe place …

Parental Responsibility Of Children Crime In Indonesian Criminal Adat Law, Ahmad Irzal Fardiansyah, Sigid Suseno, Mien Rukmini, Lies Sulistiani

Jurnal Hukum & Pembangunan

Children who are in conflict with the law cannot be separated from the responsibilities of parents as the first party in the childs environment. The relationship between parents and children is a harmonized relationship from a strong emotional connection on the basis of blood relations. This situation makes parents unable to release and be released responsibility for their childrens behavior. When children are faced with the law, policies to take over the responsibility of supervising children from parents, by denying that parents actually have the opportunity to deal with the problems of children who are dealing with the law are …
