Factors affecting people’s participation in joint forest management programmes in Kinnaur district of Himachal Pradesh, India
The present investigation examined the various factors affecting people's participation in the planning, implementation and maintenance of JFM programmes in the tribal distrct (Kinnaur) of Himachal Pradesh. In total, 10 factors were identified that influence people’s participation in Joint Forest Management (JFM) activities in the study area, which were independently affecting in all of three development blocks. District as a whole factors affecting in decreasing order were Lack of awareness about participatory forest management (66%), lack of co-ordination with forestry officials (64%), non availability of routine funds (56%), lack of training and visit programme (56%), clash between agriculture and JFM activities (54%), lack of emphasis on quick economic activities (49%), improper usufruct sharing (43%) etc. were some of major factors that influenced people’s participation. Policy and development emphasis on these factors, particularly taking into consideration the geography and need based activity in the various development blocks will increase the people’s participation in similar kind of projects
Simulation of dimensionality effects in thermal transport
The discovery of nanostructures and the development of growth and fabrication
techniques of one- and two-dimensional materials provide the possibility to
probe experimentally heat transport in low-dimensional systems. Nevertheless
measuring the thermal conductivity of these systems is extremely challenging
and subject to large uncertainties, thus hindering the chance for a direct
comparison between experiments and statistical physics models. Atomistic
simulations of realistic nanostructures provide the ideal bridge between
abstract models and experiments. After briefly introducing the state of the art
of heat transport measurement in nanostructures, and numerical techniques to
simulate realistic systems at atomistic level, we review the contribution of
lattice dynamics and molecular dynamics simulation to understanding nanoscale
thermal transport in systems with reduced dimensionality. We focus on the
effect of dimensionality in determining the phononic properties of carbon and
semiconducting nanostructures, specifically considering the cases of carbon
nanotubes, graphene and of silicon nanowires and ultra-thin membranes,
underlying analogies and differences with abstract lattice models.Comment: 30 pages, 21 figures. Review paper, to appear in the Springer Lecture

Self-Assembly for Integration of Microscale Thermoelectric Coolers
Optimum thermoelectric cooling (TEC) solutions often require the integration of component sizes inaccessible by common manufacturing techniques such as thin-film processing and robotic assembly. This work considers an application case in which small elements (100 μm to 300 μm thick) are optimal. A capillary self-assembly process is presented as a potential route to manufacturing TECs in these size ranges. A millimeter-scale demonstration of the assembly concept is presented and Monte Carlo simulation is used to study the scaling of the self-assembly approach to assemblies with more components. While assembly rate and system yield can be a challenge, several approaches are presented for increasing both rate and yield
