Neurological deterioration sometimes follows removal of cerebro-spinal fluid by lumbar puncture below a spinal block caused by a tumour. Experience has shown that similar impaction of a spinal intradural tumour may occur following the draining of hydrocephalus. We have used the term "upward spinal coning " to describe this and report four cases in which impaction of an intradural metastasis occ...

Does Mental Productivity Decline with Age? Evidence from Chess Players We use data on international chess tournaments to study the relationship between age and mental productivity in a brain-intensive profession. We show that less talented players tend to leave the game in the earliest phases of their career. When the effects of age on productivity vary with unobserved ability, commonly used fi...

The 2014 Indian general election marked a single party – the Bharatiya Janata Party, winning a majority of seats in Lok Sabha, the first time since the 1984 election. The Congress, the other main national party, suffered its worst ever defeat. This election was termed by some as a 'critical election' signalling the advent of a new phase of a ‘BJP dominated’ party system in India. In this paper,...

The samples were treated with the recommended dose of malathion, rate phosphine, powders and extracts each (ficus, camphor, clove), powder copper nanoparticles untreated seed as a control treatment. Treated stored in different packages (Jute, Plastic Polyethylene) for months. most important results can be summarized follows: Increasing storage periods wheat up to months significantly affected e...

To evaluate deterioration of oat seeds during storage, we analyzed oxygen radicals, antioxidant enzyme activity, proline content, and gene transcript levels in oat seeds with different moisture contents (MCs; 4, 16, and 28% w/w) during storage for 0, 6, and 12 months (CK, LT-6, and LT-12 treatments, respectively) at 4°C. The germination percentage decreased significantly with higher seed MCs an...

Seed priming (controlled hydration followed by drying) is used to alleviate high temperature inhibition of germination and improve seedling emergence of lettuce (Lactuca sativa L.) and other species. However, seed priming can also reduce the longevity of seeds during dry storage. Alternative drying methods [i.e., slow drying or moisture content reduction (MCR) before drying] can extend seed lon...
