An eight month old male infant with protein energy malnutrition was admitted in the hospital with the history of repeated attacks of convulsion since four months of age. He was also suffering from frequent attacks of cough and cold since 6 months of age which was marked prior to admission. The infant had fair complexion, sparse fuzzy wooly hair with marked trunkal hypotonia. He had also mental ...

This paper documents tax-minimizing investment, in which firms accelerate capital purchases near fiscal year-end to reduce taxes. Between 1984 and 2013, average investment in the fourth fiscal quarter (Q4) is 37% higher than the average of the first three fiscal quarters. Q4 investment spikes also occur internationally. We use research designs based on variation in firm tax positions and the 19...

Menkes kinky hair disease is a rare X-linked recessive disease nearly exclusively affecting males who present at 2-3 months of age due to abnormal functioning of copper-dependent enzymes due to deficiency of copper. Here, we describe a completely worked-up case of a 4-month-old male infant with very typical history and radiological features confirmed by biochemical and trichoanalysis. The initi...

Using a first-principles approach based on density-functional theory, we find that a large tetragonal strain can be induced in PbTiO3 by application of a negative hydrostatic pressure. The structural parameters and the dielectric and dynamical properties are found to change abruptly near a crossover pressure, displaying a ‘‘kinky’’ behavior suggestive of proximity to a phase transition. Analogo...

"Black-short ears-kinky tail-rodless" mice, controlled by "pink eyed-dilute-brown" mice, were tested on an inclined plane in order to determine if they are photically sensitive, and, if so, to get a quantitative expression for their visual receptivity. Rodless and control animals were tested in the dark to obtain an expression for normal geotropic orientation. Light was then introduced to modif...
