The phytohormone abscisic acid(ABA)is a 15-carbon molecule that fulfills essential functions in all *** regulates many as-pects of plant life,including growth and development,seed dormancy and germination,leaf senescence,and responses to various biotic and abiotic stresses(Finkelstein 2013).Due to the latter functions,ABA is also known as the"stress phytohormone."As in the case of other hormones,the level of ABA in the cells is critical for its precise regulatory functioning.

Satluj Valley is known to have a history of landslides and related mass movement activities since the geological times. Geological and geomorphological settings combined with anthropogenic activities constitute a propensity towards slope failure. During the last two decades,the area witnessed substantial increase in athropogenic pressure,mainly due to the exploitation of hydropower potential,changing landuse pattern and population growth. In addition,a shift of the climatic patterns in the form of larger area falling under the influence of rains was observed. These natural as well as anthropogenic changes in the area have resulted in increased spatial coverage of landslide in the area. This paper documents these changes during 1990～2006.

In our simplified description‘wealth’is money(m).A kinetic theory of a gas like model of money is investigated where two agents interact(trade)selectively and exchange some amount of money between them so that sum of their money is unchanged and thus total money of all the agents remains *** probability distributions of individual money(P(m)vs.m)is seen to be influenced by certain ways of selective *** distributions shift away from Boltzmann-Gibbs like the exponential distribution,and in some cases distributions emerge with power law tails known as Pareto’s law(P(m)/m−(1+®)).The power law is also observed in some other closely related conserved and discrete models.A discussion is provided with numerical support to obtain insight into the emergence of power laws in such models.

We have investigated the electronic properties of WTe2 armchair nanoribbons with defects. WTe2 nanoribbons can be categorized depending on the edge structure in two types： armchair and zigzag. WTe2 in its bulk form has an indirect band gap but nanoribbons and nanosheets of WTe2 have direct band gaps. Interestingly, the zigzag nanoribbon is metallic while the armchair nanoribbons are semiconducting. Thus they can find applications in device fabrication. Therefore, it is very important to study the effect of defects on the electronic properties of the armchair nanoribbons as these defects can impair the device properties and characteristics. We have considered defects such as： vacancy, rough edge, wrap, ripple and twist in this work. We report the band gap variation with these defects. We have also studied the change in band gap and total energy with varying degrees of wrap, ripple and twist.
