A regional-level and dimensionless analysis for designing a domestic rainwater harvesting system (DRWHS) was developed. To consider various combinations of water demand, storage capacity, effective roof area, and rainfall in DRWHS design, two dimensionless ratios were used, namely, demand fraction and storage fraction, along with a relationship between the two ratios. Firstly, Northern Taiwan w...

A method for speciation and determination of low levels of dissolved iron in rainwater was established by coupling reverse flow injection analysis with a 2-m liquid waveguide capillary cell and spectrophotometric detection. Ferrozine solution was injected into a sample stream to form an Fe(II)-ferrozine complex with Fe(II), and the absorbance of this complex was detected at both 562 nm and 625 ...

Urban water services in the Australian Capital Territory (ACT) are currently provided through conventional centralised systems, involving large scale water distribution, wastewater collection, water and wastewater treatment. A study was conducted to assist Environment ACT in setting broad policies for future water services in Canberra. This paper presents the outcomes of a study examining the e...

We study borrowers’ optimal choice between formal and informal sources of credit in a setting with strategic default due to limited enforcement. Informal loans (e.g., from friends or relatives) can be enforced by the threat of severing social ties which hurts both the borrower and the lender, while formal loans (e.g., from banks) are enforced by requiring collateral. We show that in this settin...

This paper presents a brief overview of the Power of Numbers project (the “Project”), an independent research initiative involving 17 scholars and coordinated by Sakiko Fukuda-Parr (The New School) and Alicia Ely Yamin (Harvard University). It arose out of a shared concern amongst the 17 participating scholars with the need to more fully understand the consequences of the Millennium Development...

Exploiting the tension between two dynamics of quantum theory (QT) in Wigner's Friend thought experiment, we point out that standard QT leads to inconsistency observed probabilities measurement outcomes superobservers: Wigner and his Student. To avoid such inconsistent predictions QT, hypothesize distinct perspectives. The first one is ``absoluteness (AoM),'' is, any process an absolute event i...

With water becoming an even scarcer resource, rainwater harvesting (RWH) systems are becoming increasingly more commonplace as mechanisms to capture and store rainwater for both agricultural and domestic use. Three important engineering considerations associated with the construction of RWH systems are the capture surface area, the tank volume required for specific demand levels, and the number...

This paper explores the e ects of rainwater harvesting (RWH) on aggregate household labor supply in areas prone to droughts. Using a Brazilian survey on rainwater harvesting, we nd that having a RWH infrastructure at the homestead increases household wellbeing through three channels: (i) a direct time allocation e ect since households spend less time fetching water from distant sources, the tim...

Preparations of pooled Friend virus used in this laboratory were found to contain lactate dehydrogenase (LDH) virus. Interrelationships between these viruses and the effects of drug treatment i~ vivo and virus neutralization in vitro were studied. Both 6-mercaptopurine and streptonigrin administered to Friend virus-infected mice delayed the onset of the 10to 100-fold normal elev,%tion of plasma...
