Impact of Climate, Climate Change and Modern Technology on Wheat Production in Nepal: A Case Study at Bhairahawa
Janak Lal Nayava,Rabi Singh,Madan Raj Bhatta
Journal of Hydrology and Meteorology , 2009, DOI: 10.3126/jhm.v6i1.5479
Abstract: The relation between climate and wheat production in Nepal was studied for the period 1970/71-2007/08. Due to the topographical differences within short north-south span of the country, Nepal has wide variety of climatic condition. About 70 to 90% of the rainfall occurs during the summer monsoon months (June to September) in Nepal and the rest of the months are almost dry. Wheat is cultivated during the dry winter period and therefore, the supplementary irrigation plays a vital role in its cultivation. Varieties of wheat have been developed to suit the local climatic conditions. Due to the availability of improved seeds, modern cultivation practice and a supplementary irrigation; the wheat cultivation has increased substantially throughout Nepal. The national area and production of wheat has remarkably increased from 228,000 ha to 706,481 ha and 193360 mt to 1,572,065 mt during 1970/71 to 2007/2008 respectively. Future planning to increase the wheat production in Nepal should give due consideration to the effect of global warming also. The present rate of annual increase of temperature was 0.06°C in Nepal. Trends of temperature rise were not uniform in Nepal. An increase of annual temperature at Bhairahawa during 1970-2008 was only 0.018°C. However, the wheat growing seasons at Bhairahawa, the trend of annual maximum temperature during November to April was -0.0068°C during the study period. Though modern facilities such as irrigation, improved seeds and fertilizers are available to some extent, weather and climate still plays an important role in the increase of area and production of wheat in Nepal

“Women are the pillars of Our Culture”: Bohna as a resurgent cloth among the Dhimal
Janak Rai
Dhaulagiri Journal of Sociology and Anthropology , 2014, DOI: 10.3126/dsaj.v8i0.10724
Abstract: Bohna is the traditional ethnic dress woven and worn by Dhimal women. It is an everyday dress which Dhimal women wear it in all kinds of social spaces and events: home, fields, markets, cinema halls, colleges, mela, and other places. In the recent decades, with the resurgence of indigenous political movements and Dhimals’ localized social movements for revival of their customary practices, bohna has emerged as a powerful marker of Dhimal indigenous identity. This paper examines the historical, cultural and political embeddedness of bohna in Dhimal society. The paper highlights the creative agency of Dhimal women by showing how weaving and exchange of bohna recreate and connect the embedded relations of affection, exchange and mutual obligations between Dhimal women.
Maximal small extensions of o-minimal structures
Janak Ramakrishnan
Mathematics , 2007, DOI: 10.1002/malq.200910102
Abstract: A proper elementary extension of a model is called small if it realizes no new types over any finite set in the base model. We answer a question of Marker, and show that it is possible to have an o-minimal structure with a maximal small extension. Our construction yields such a structure for any cardinality. We show that in some cases, notably when the base structure is countable, the maximal small extension has maximal possible cardinality.
Functions continuous on curves in o-minimal structures
Janak Ramakrishnan
Mathematics , 2009,
Abstract: We give necessary and sufficient conditions on a non-oscillatory curve in an o-minimal field such that, for any bounded definable function, the germ of the function on an initial segment of the curve can be continuously extended to a closed definable set. This situation is translated into a question about types: What are the conditions on an $n$-type such that, for any bounded definable function, there is a definable set containing the type on which the function is continuous, and can be extended continuously to the set's closure? All such types are definable, and we give the precise conditions that are equivalent to existence of a desired definable set.
Uniform bounds on growth in o-minimal structures
Janak Ramakrishnan
Mathematics , 2007, DOI: 10.1002/malq.200910031
Abstract: We prove that a function definable with parameters in an o-minimal structure is bounded away from infinity as its argument goes to infinity by a function definable without parameters, and that this new function can be chosen independently of the parameters in the original function. This generalizes a result in a paper of Friedman and Miller. Moreover, this remains true if the argument is taken to approach any element of the structure (or plus/minus infinity), and the function has limit any element of the structure (or plus/minus infinity).
Definable linear orders definably embed into lexicographic orders in o-minimal structures
Janak Ramakrishnan
Mathematics , 2010,
Abstract: We completely characterize definable linear orders in o-minimal structures expanding groups. For example, let (P,<_p) be a linear order definable in the real field R. Then (P,<_p) embeds definably in (R^{n+1},<_l), where <_l is the lexicographic order and n is the o-minimal dimension of P. This improves a result of Onshuus and Steinhorn in the o-minimal group context.
Multiple Density Subdural Hematomas  [PDF]
Divye Prakash Tiwari, Vivek Sharma, Janak Raj
Open Journal of Modern Neurosurgery (OJMN) , 2014, DOI: 10.4236/ojmn.2014.41004
Abstract: The chronic subdural hematoma is a well known entity in old age and the treatment is very challenging. Treatment protocol depends upon the radiological finding. The loculation and multilayering indicates the bleeding at multiple times and respectively found in 13.2% and 13.6%, which was more common in patients more than 75 years. Burr hole evacuation was the treatment of choice except in recurrent cases where craniotomy was performed.
Stationary Solutions of a Mathematical Model for Formation of Coral Patterns  [PDF]
Lekam Watte Somathilake, Janak R. Wedagedera
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.66100
Abstract: A reaction-diffusion type mathematical model for growth of corals in a tank is considered. In this paper, we study stationary problem of the model subject to the homogeneous Neumann boundary conditions. We derive some existence results of the non-constant solutions of the stationary problem based on Priori estimations and Topological Degree theory. The existence of non-constant stationary solutions implies the existence of spatially variant time invariant solutions for the model.
