Some new results on irradiation characteristics of synthetic quartz crystals and their application to radiation hardening

The paper reports some new results on irradiation characteristics of synthetic quartz crystals and their application to radiation hardening. The present results show how the frequency shift in quartz crystals can be influenced by heat processing prior to irradiation and how this procedure can lead to radiation hardening for obtaining precise frequencies and time intervals from quartz oscillators in space

Some new results on the frequency characteristics on quartz crystals irradiated by ionizing and particle radiations

The frequency behavior of AT-cut quartz crystals irradiated by X -, gamma rays and fast neutrons. Initial instability in frequency for gamma and neutron irradiated crystals was found. All the different radiations first give a negative frequency shift at lower doses which are followed by positive frequency shift for increased doses. Results are explained in terms of the fundamental crystal structure. Applications of the frequency results for radiation hardening are proposed

Road Expansion and Urban Highways: Consequences Outweigh Benefits in Kathmandu

Rapid urbanization has transformed Kathmandu Valley, Nepal, one of the fastest growing metropolitan regions in South Asia. This urbanization, in turn, is leading to considerable social, economic, and environmental stress. The region has seen unplanned growth despite continued planning exercises. In 2011, in response to the rapid urbanization then Prime Minster Baburam Bhattarai initiated road expansion throughout the city to reduce traffic congestion. By mid 2015, it was clear that the road expansion induced greater demand leading to further traffic congestion rather than alleviating the problem. Today, non-motorized (pedestrians and bicycle) road users are more unsafe on the roads than ever before, and the plight of public transport users has remained the same. Traffic congestion has become a more serious problem. Air pollution associated with road construction and an increasing number of vehicles has turned the Kathmandu Valley into a dust bowl with potential for serious human health consequences. Along with road expansion, the government’s inability to regulate land use has contributed to Kathmandu’s current urban sprawl. Road expansion done without proper planning has threatened traditional settlements, many with heritage sites, and led to loss of public spaces and temple courtyards to make space for increasing demand for parking. Another major landscape change has been the building of concrete embankments and exclusive motor roads along the river corridors. The road expansion campaign is still ongoing and is a top priority of the government’s efforts to reduce congestion and improve urban transportation. It is high time the government of Nepal rethinks its vehicle-centric urban transport policy and adopts policy where mobility of people is prioritized. Urban transport planning should work to build a more equitable and inclusive city while addressing accessibility, safety, and environmental health risks of its growing urban population.

Rural Nonfarm Employment and Incomes in the Himalayas

Nonfarm activities generate on average about 60 percent of rural households incomes in the Himalayas. This paper analyzes the determinants of participation in nonfarm activities and of nonfarm incomes across rural households. A unique data set collected in the Himalayan region of India allows us to deal with the heterogeneity of rural nonfarm activities by using aggregations into categories that are useful both analytically and for policy purposes. We conduct an empirical inquiry that reveals that education plays a major role in accessing more remunerative nonfarm employment. Other household assets and characteristics such as land, social status, and geographical location also play a role.Nonfarm employment, Rural households, Incomes, education, India
