Class V myosin (myosin-V) is a cargo transporter that moves along an actin filament with large (approximately 36-nm) successive steps. It consists of two heads that each includes a motor domain and a long (23 nm) neck domain. One of the more popular models describing these steps, the hand-over-hand model, assumes the two-headed structure is imperative. However, we previously succeeded in observ...

Part 6 of the Manual on Uniform Traffic Control Devices (MUTCD) describes several types of channelizing devices to warn and guide road users through work zones, including cones, tubular markers, vertical panels, drums, barricades, and temporary raised islands. On higher speed/volume roadways, drums and/or vertical panels have been popular choices in many states due to enhanced visibility and a ...

They must be grown according to proper conditions of sanitation and handled as a food product rather than as an agricultural commodity. When sprouts are grown in accordance with the criteria proposed from within th...

This paper deals with a comparative analysis of two different packaging and transport scenarios, which exemplifies the implications of choosing between single-use and reusable packaging. In particular, transport of a batch of chemicals by means of disposable fibre drums vs. reusable steel drums is investigated from a life cycle perspective, and the associated environmental impact in terms of Gl...

This paper estimates whether female-headed households are poorer than their male-headed counterparts, using household data from the National Family Health Survey (NFHS) for the year 2005-06. I use poverty measures that reflect on people’s permanent income such as housing condition, wealth index and standard of living index, and argue that these measures could be more informative about the chron...

A B S T R A C T This study investigates the production of Quechua relative clauses by Peruvian adults and children, aged 2;8–4;7. Quechua relative clauses may be internally-headed, externally-headed or headless. Previous studies (e.g., O'Grady, 2003), suggested two outcomes: children will have less difficulty producing subject-gap relative clauses than other types; and, compared with adults, ch...

"[A] sample of 680 working women will be used to analyse the economic situation of households headed by women relative to households headed by men. The paper will compare income levels, household size and composition and employment patterns in the two sets of households. Further, the stu...
