A Quasi experimental study to compare the effects of cool gel packs versus analgesics on post-episiotomy pain reduction in selected hospital Shimla, Himachal Pradesh, India
No full textABSTRACT
Introduction-Pain after episiotomy has reported as the common cause of maternal morbidities in postnatal period. Studies have shown that cold therapy is effective in reducing post episiotomy pain.So the study aimed to compare the effect of cool gel packs versus analgesics on post episiotomy pain reduction in order to improve nursing care practices and to provide maximum comfort to postpartum women.
Method-The research design was quasi experimental and was conducted from Dec. 2023 in obstetrics department of Indra Ghandi medical collage & Hospital Kamala Nehru State Hospital Mother &Child Shimla on 60 subjects (30 for experimental and 30 for control group) of Shimla, Himachal Pradesh. Intervention in experimental group was application of cool gel packs and in control group was administration of analgesic (as per hospital routine). The socio- Demographic sheet which was structured interview schedule was filled by investigator. Level of pain of postpartum women after normal delivery with episiotomy is assessed by using subjective and objective tool. Pre-intervention and post-intervention assessment (at 0, 30 and 60 min) was done for both the groups.
Results -The results of the study revealed that most of study subjects experienced mild to moderate level of post-episiotomy pain. Cool gel packs help in reduction of post-episiotomy pain in experimental group at 0, 30 and 60 min. With NRS, Cool gel packs were more effective in reducing post-episiotomy pain at 0 min and 30 min of time in experimental group as compared to analgesics in control group but at 60 min of time both analgesics and cool gel packs were equally effective. With BPS, Cool gel packs were more effective in reducing post-episiotomy pain at 0 min, 30 min and at 60 min. No association of post-episiotomy pain with age, parity, duration of 2nd stage of labour, sex of the child was found in the study.
Conclusion- Hence it can be concluded that Cool gel packs are more effective in reducing post episiotomy pain in comparison to analgesics up to 30 min

Adaptation, gyro-ree stabilization, and smooth angular velocity observers for attitude tracking control applications
No full texttextThis dissertation addresses the problem of rigid-body attitude tracking control under three scenarios of high relevance to many aerospace guidance and control applications: adaptive attitude-tracking control law development for a spacecraft with time-varying inertia parameters, velocity-free attitude stabilization using only vector measurements for feedback, and smooth angular velocity observer design for attitude tracking in the absence of angular velocity measurements. Inertia matrix changes in spacecraft applications often occur due to fuel depletion or mass displacement in a flexible or deployable spacecraft. As such, an adaptive attitude control algorithm that delivers consistent performance when faced with uncertain time-varying inertia parameters is of significant interest. This dissertation presents a novel adaptive control algorithm that directly compensates for inertia variations that occur as either pure functions of the control input, or as functions of time and/or the state. Another important problem considered in this dissertation pertains to rigid-body attitude stabilization of a spacecraft when only a set of inertial sensor measurements are available for feedback. A novel gyro-free attitude stabilization solution is presented that directly utilizes unit vector measurements obtained from inertial sensors without relying on observers to reconstruct the spacecraft's attitude or angular velocity. As the third major contribution of this dissertation, the problem of attitude tracking control in the absence of angular velocity measurements is investigated through angular velocity observer (estimator) design. A new angular velocity observer is presented which is smoothed and ensures asymptotic convergence of the estimation errors irrespective of the initial true states of the spacecraft. The combined implementation of a separately designed proportional-derivative type controller using estimates generated by the observer results in global asymptotic stability of the overall closed-loop tracking error dynamics. Accordingly, a separation-type property is established for the rigid-body attitude dynamics, the first such result to the author's best knowledge, using a smooth (switching-free) observer formulation.Aerospace Engineerin
A REVIEW ON MEDICINAL PLANTS FOR THE MANAGEMENT OF OSTEOPOROSIS
No full textABSTRACT
From ancient times many medicinal herbs have been reported in literature to treat osteoporosis. Natural Products are also a part of our everyday life. Right from the inception, India has a rich heritage of usage of Ayurvedic & Herbal medicines Herbal have just recently started rising on the horizon of alternative system of medicine. Ayurveda and Herbal were being practiced and used all over the world for many years but have only recently started getting legal acceptance in many countries in the world as alternative system of medicine. India is called “Botanical Garden of the world” as it is the largest producer of medicinal herbs. Out of more than 25000 plants of medicinal value, only 10 % are used for their medicinal value. Around 1800 species are systematically documented in the codified Indian systems of medicine. These herbal products are preventive, protective, nutritive and curative. This Review is made to list out the Medicinal plants, which have been reported to have Anti osteoporotic activity against various animal models.
Key words: Osteoporosis, Medicinal plants, Overeictomized rat model, Glucocorticoid induced Osteoporosis and in vitro methods.
