A generic problem encountered in process improvement involves simultaneous optimization of multiple responses (so-called 'critical response/output characteristics'). These types of problems are also referred to as 'multiple response optimization (MRO) problems'. The primary goal of any process improvement initiative is to determine the best process(More)
The developmental profiles of gamma-aminobutyric acid (GABA), its biosynthesizing enzyme L-glutamic acid decarboxylase (GAD) and its degradating enzymes gamma-aminobutyric acid-alpha-ketoglutaric acid transaminase (GABA-T) and succinic semialdehyde dehydrogenase (SSADH) in four different regions of human fetal brains have been evaluated. The GABA pathway(More)
Axon collaterals emerging from the vasopressinergic neurons of the supraoptic (SON) and paraventricular (PVN) nuclei and recurving back towards their respective nuclei have been previously reported. Since such axon collaterals can play a role in the neuromodulation of SON and PVN, these nuclei have been further investigated immunohistochemically under the(More)
BACKGROUND In this study, the measurement of job stress of electric overhead traveling crane operators and quantification of the effects of operator and workplace characteristics on job stress were assessed. METHODS Job stress was measured on five subscales: employee empowerment, role overload, role ambiguity, rule violation, and job hazard. The(More)
Mandibular resection following surgical treatment for neoplastic lesions of the oral cavity leads to numerous complications including altered mandibular movements, disfigurement, difficult in swallowing, impaired speech and articulation, and deviation of the mandible towards the resected site. Various prosthetic methods are employed to reduce or minimize(More)
BACKGROUND One out of every two children sustains a dental injury most often between 8 and 10 years of age. Majority of these teeth subsequently become non-vital and most often with immature apex. Management of these teeth is an enormous challenge for lack of apical stop. Calcium hydroxide in various formulations has maximum literature support in favor of(More)
