Abstract

The rocks of the Archaean basement complex and the overlying sedimentary sequences in the southern parts of the Bundelkhand in Lalitpur-Jhansi region, Uttar Pradesh are divided into tectonic blocks, within which broad but distinct stratigraphic units are recognised and classified. Recent mapping suggests that the entire area was subject to two major phases of sedimentary-volcanic process before regional granitisation during the Archaean. Granitisation, in preferred tectonic block, led to the development of an intra-cratonic belt controlled between lineaments, within which the younger Bijawar-Vindhyan basins developed.

The results of exploration done so far suggest that base-metals, gold, uranium and possible nickel mineralisation occurs within the different stratigraphic-tectonic environments recognised in this area.

Abstract

This article explores the process by which young adults shape their early stages of adult life. The analysis is carried out for a society which is traditional in nature and under the wave of contemporary societal changes. The young people’s transition into marriage is analyzed to examine whether the practice of early marriage still prevails in the traditional society or is governed by the law of normative sequencing of life cycle, that is education, employment, and marriage. Using age-wise retrospective primary data, the determinants of marriage timing are also analysed here.

Abstract

In the present study Shri Devi Bhavan Dairy farm Complex was selected for the energy auditing. It consists of three sections (i) Dairy farm, (ii) School, (iii) Temple Complex. The survey was carried out for the basic data collection regarding energy demands and resources availability in all the sections. The data was analyzed for determining total energy demand and resources availability in all sections. The survey of major activities related to use of thermal, electrical, mechanical and human energy was conducted and total energy demand and energy use pattern was also studied in this selected area. The data for energy demands and resource availability in Devi Bhavan Dairy farm Complex were collected with the help of well structured questionnaire developed for the purpose. The type of energy sources utilized in the dairy farm complex was electrical, thermal, mechanical and manual. The electrical energy was the only source of energy used in School and Temple Complex. The value of manual, electrical, thermal and mechanical energy required per month for dairy farm was 5997.6, 1509.2, 27600 and 9540 MJ/Month respectively. In case of school and temple complex demand of electrical energy per month was 2216.16 and 5715.36 MJ/Month respectively.

Abstract

Introduction: High band pass filtering of evoked potentials have produced the results of decreased early High frequency oscillations (HFOs) in previous studies of migraine patients. However, in most of these studies, the study population has been heterogeneous. The only study till date which used homogenous drug naive group of patients has actually produced contradictory results to the previous studies showing. Aim: We aimed to clarify the status of HFO amplitudes and latencies in drug-naive newly diagnosed patients. Methods: In the present study, we evaluated the 20 newly diagnosed and drug naive migraine patients using electrophysiological assessments using Somatosensory evoked potentials (SSEPs) and compared their SSEP parameters with those of the healthy age and gender matched normal controls. Median nerve SSEP was obtained by standard protocols. High frequency oscillations were extracted from the broad-band evoked potentials by digitally filtering using high pass filtering at 450Hz-1KHz. Early HFOs were identified when occurred before the N20 peak. Results: No differences were observed in the broad-band SSEPs i.e., N20 amplitudes and latencies. The maximal peak to peak amplitudes in the drug naïve migraineurs in between the attacks for the early HFOs (occurring before the N20 peak) were significantly smaller than the normal controls (p=0.046). The number of negative peaks were also fewer in the migraineurs in a statistically nonsignificant way. Discussion: This is the first HFO study on a homogenous population of migraineurs which shows decreased early HFOs, thus implicating weaker thalamocortical activity and contradicting the results by Lai et al¹.
