Elucidating Structural Disorder in Ultra-Thin Bi-Rich Bismuth Oxyhalide Photocatalysts

Marks, M.J. (author), Jeppesen, Henrik (author), Nielsen, Mads Lund Nygaard (author), Kong, J. (author), Ceccato, Marcel (author), van der Veen, M.A. (author), Bøjesen, Espen Drath (author), Lock, Nina (author)

Advancing the field of photocatalysis requires the elucidation of structural properties that underpin the photocatalytic properties of promising materials. The focus of the present study is layered, Bi-rich bismuth oxyhalides, which are widely studied for photocatalytic applications yet poorly structurally understood, due to high levels of...

Climate impact mitigation potential of formation flight

Marks, Tobias (author), Dahlmann, Katrin (author), Grewe, V. (author), Gollnick, Volker (author), Linke, Florian (author), Matthes, Sigrun (author), Stumpf, Eike (author), Swaid, Majed (author), Unterstrasser, Simon (author)

The aerodynamic formation flight, which is also known as aircraft wake-surfing for efficiency (AWSE), enables aircraft to harvest the energy inherent in another aircraft’s wake vortex. As the thrust of the trailing aircraft can be reduced during cruise flight, the resulting benefit can be traded for longer flight time, larger range, less fuel...

Assessing the climate impact of formation flights

Dahlmann, K. (author), Matthes, Sigrun (author), Yamashita, H. (author), Unterstrasser, S. (author), Grewe, V. (author), Marks, Tobias (author)

An operational measure to aim for mitigation of aviation climate impact that is inspired by migrant birds is to fly in aerodynamic formation. This operational measure adapted to human aircraft would eventually save fuel and is, therefore, expected to reduce the climate impact of aviation. As this method changes beside the total emission also the...

Assessing Drinking Water Quality at the Point of Collection and within Household Storage Containers in the Hilly Rural Areas of Mid and Far-Western Nepal

Daniel, D. (author), Diener, Arnt (author), van de Vossenberg, Jack (author), Bhatta, Madan (author), Marks, Sara J. (author)

Accurate assessments of drinking water quality, household hygenic practices, and the mindset of the consumers are critical for developing effective water intervention strategies. This paper presents a microbial quality assessment of 512 samples from household water storage containers and 167 samples from points of collection (POC) in remote...

Combining sanitary inspection and water quality data in western Uganda: Lessons learned from a field trial of original and revised sanitary inspection forms

Daniel, D. (author), Gaicugi, Josphine (author), King, Richard (author), Marks, Sara J. (author), Ferrero, Giuliana (author)

Risk assessment for drinking water systems combines sanitary inspections (SI) and water quality testing and is critical for effectively managing the safety of these systems. SI forms consist of question sets relating to the presence of potential sources and pathways of contamination specific to different types of water points, piped...

Assessing the climate impact of formation flights

Dahlmann, Katrin (author), Matthes, Sigrun (author), Yamashita, Hiroshi (author), Unterstrasser, Simon (author), Grewe, V. (author), Marks, Tobias (author)

An operational measure that is inspired by migrant birds aiming toward the mitigation of aviation climate impact is to fly in aerodynamic formation. When this operational measure is adapted to commercial aircraft it saves fuel and is, therefore, expected to reduce the climate impact of aviation. Besides the total emission amount, this...

Understanding the effect of socio-economic characteristics and psychosocial factors on household water treatment practices in rural Nepal using Bayesian Belief Networks

Daniel, D. (author), Diener, Arnt (author), Pande, S. (author), Jansen, S.J.T. (author), Marks, Sara (author), Meierhofer, Regula (author), Bhatta, Madan (author), Rietveld, L.C. (author)

About 20 Million (73%) people in Nepal still do not have access to safely managed drinking water service and 22 million (79%)do not treat their drinking water before consumption. Few studies have addressed the combination of socio-economic characteristics and psychosocial factors that explain such behaviour in a probabilistic manner. In this...

Socio-environmental drivers of sustainable adoption of household water treatment in developing countries

Daniel, D. (author), Marks, Sara J. (author), Pande, S. (author), Rietveld, L.C. (author)

Household water treatment (HWT) can effectively reduce exposure to unsafe drinking water at home. Understanding the characteristics of target groups who successfully adopt HWT, such as perception about water quality and usefulness of HWT, income, or parental education, is essential for enhancing the adoption of HWT in developing countries. The...

The Apollo assembler

Marks, B.L. (author)

An assembly program has been developed so that programs written in a convenient language can be read into the Apollo digital computer. This Note explains why an assembler was decided upon and describes the rejected alternatives. The language is described in detail so that a section of the Note can act as a reference manual. Details are given of...

A digital simulation study of the relation between regularity of arrivals and congestion in a queueing system: with particular reference to runway utilization

Marks, B.L. (author)

A queueing model is considered in which the amount of bunching in the arrival times is a parameter of the system. The process was simulated on a Ferranti 'Mercury' computer, within the framework of a more general program. The model and the results are described in terms of aircraft using a runway and suggest a new aspect of terminal air traffic...

Adjustments rules for automatic tracking

Marks, B.L. (author)

A simple group of formulae are considered for the repeated adjustment of estimated aircraft tracks which are maintained in a digital computer. The adjustments are based on reports of the position of the aircraft obtained at equal time intervals in digital co-ordinate form. The group of formulae considered, called adjustment rules, are those in...
