Electrically modulated photoluminescence in ferroelectric liquid crystal

Electrical modulation and switching of photoluminescence (PL) have been demonstrated in pure deformed helix ferroelectric liquid crystal (DHFLC) material. The PL intensity increases and peak position shifts towards lower wavelength above a threshold voltage which continues up to a saturation voltage. This is attributed to the helix unwinding phenomenon in the DHFLC on the application of an electric field. Moreover, the PL intensity could be switched between high intensity (field-on) and low intensity (field-off) positions. These studies would add a new dimension to ferroelectric liquid crystal's application in the area of optical devices.Comment: 4 figure

A study on health profile of geriatric population in an urban slum of bijapur

Background: Advances in medical field have increased the longevity of people by reducing morbidity and mortality to a great extent. With the increase in longevity, problems related to old age have also increased. These problems are more confounded by social factors. Objective: To assess the various health problems faced by elderly people and suggest the remedial measures so that effective preventive and promotive measures can be implemented. Methodology: Community based cross-sectional study of the elderly persons residing in an urban slum of Bijapur. Results: Among acute health problems most common were arthritis (39%) and bronchitis (20.8%). Most common chronic illness observed was respiratory illness 19% (COPD and asthma) fallowed by visual impairment (11.5%), arthritis (11.1%), and hypertension (9.1%) Mini Mental State Examination (MMSE) showed that majority of respondents 297 (60%) were having the normal score. Conclusion: The pattern of geriatric health problems have different characteristics and hence require a specific type of screening programme based on the finding of various geriatric health studies

The study of left ventricular relaxation and filling abnormalities in acute coronary syndrome by doppler echocardiography

Objectives: To study the left ventricular relaxation and filling abnormalities by doppler echocardiography and prognosis of acute coronary syndrome. Methods:  Fifty patients of acute coronary syndrome were included in the study. The left ventricular diastolic dysfunction was studied using doppler transmitral velocities within the apical 4- chambers view (1st study-on the day of admission and 2nd study- after one week). The various parameters studied were peak E (peak rapid filling velocity), peak A (atrial contraction wave), E/A ratio, E-DT (E- deceleration time), IVRT (isovolumetric relaxation time), S-wave (systolic forward flow wave), D-wave (diastolic forward flow wave) and AR-wave (atrial reversal wave). Results: Of 50 patients studied 3 had normal, 36 patients had impaired relaxation, 5 patients had pseudo-normalization, 4 patients reversible and 2 patients irreversible restrictive filling on the day of admission (1st study). In the 2nd study (after one week) 16 were normal, 20 patients had impaired relaxation, 5 patients had pseudo-normalization, 6 patients had reversible and 2 patients had irreversible restrictive filling. Conclusion: Doppler echocardiographic assessment of left ventricular diastolic dysfunction in the setting of acute coronary syndrome helps in the management and provides independent noninvasive prognostic information

STUDY OF SERUM HOMOCYSTEINE LEVELS IN CEREBROVASCULAR ACCIDENT

Background: Stroke is the second most common cause of death and major cause of disability worldwide. Plasma homocysteine concentration is one of the emerging modifiable risk factor for stroke. The objective of this study was to evaluate the fasting homocysteine level in different type of stroke (Ischemia & Hemorrhage). MATERIAL & METHOD: The present study is case control study in which 90 patients with diagnosis of stroke (intracerebral infarct & hemorrhage) were enrolled and fasting serum homocysteine were measured in all and its comparison was done with matched healthy controls. Result: In study group the mean serum homocysteine level is 31.47±39.89µmol/L and in control group 16.62±22.08µmol/L, it indicates that serum homocysteine level is highly significantly raised (P value < 0.0001) in cases of stroke compared with control patients. However there is no significant difference in homocysteine level between intracerebral infarct and intracerebral hemorrhage (P= 0.5817). There is significant relationship of raised serum homocysteine level with hypertension & smoking. Conclusion: The present study revealed that hyperhomocysteinemia appears to be an important risk factor for cerebrovascular accidents. It is therefore important to use serum homocysteine level as an important tool to investigate all cases of cerebrovascular accidents and also in those who are at risk of developing stroke

Medicine Research in India: A Scientometric Assessment of Publications during 2009 – 2018

The purpose of this paper is to qualitative analyse of medicine research output using select scientometric indicators with the aim of identifying top preparing countries, subject subthemes, organisations, authors and journals in the area. The present study has examined 29153 publications in medicine research, the present study deals with the Assessment of Indian medicine research output as reflected in Web of Science (WOS) database for the period 2009 to 2018 for identifying the research output in the field of medicine literature. It also provides a comparative evaluation and performance of different types of scientometric indicators, such as number of publications, number of citations, relative growth, doubling time, activity index and collaboration from India. The Indian medicine research has increased exponentially over the last decade

Memory effect in weakly anchored surfaces of deformed helix ferroelectric liquid crystals

A wide-range memory effect in deformed helix ferroelectric liquid crystals (DHFLCs) has been investigated by electro-optical and textural methods. A comparative study has been performed on strongly and weakly anchored surfaces of DHFLC cells. The saturation voltage has been compared in both types of cells by studying the variation of tilt angle and spontaneous polarization with applied voltage. The long-lasting memory effect has been observed in untreated (weakly anchored) cells. It has been proposed that perfect memory in DHFLC cells without any surface treatment is due to the possibility of the absence of depolarization and ionic charges over the surfaces of the cells

Enhancement of seed germination in stored seeds using different pre-sowing treatments in Bauhinia purpurea L.

Bauhinia purpurea L. is one of the important avenue tree species used in garden, road side plantations and other places. Fresh seed produce good germination upto 75 to 100 per cent. Seeds of this species stored for five months produced less germination (38.00 %) and it could be due to seed dormancy. Hence, the present study was carried out to evaluate different seed treatments to enhance seed germination in stored seeds of B. purpurea. Treatment like soaking seeds in hot water for 2 min to 5 min followed by overnight soaking in normal water resultedin highest germination of about 59.00 per cent over control (40.00%). Significant variation for germination parameters such as mean daily germination, germination rate index and germination value as well as early seedling vigour was recorded among different pre-sowing treatments in stored seeds
