Nidhi,Archana Kumari,Sarita Tirkey,Jay Prakash 대한폐경학회 2022 대한폐경학회지 Vol.28 No.3

Objectives: To evaluate the effect of levonorgestrel-releasing intrauterine system (LNG-IUS) on heavy menstrual bleeding in perimenopausal women.Methods: This was a prospective, observational clinical study conducted on 42 perimenopausal women with heavy menstrual bleeding who met the study eligibility criteria. LNG-IUS was inserted in the postmenstrual phase following baseline evaluation. The patients were followed up at the 4, 12, and 24 weeks. Pictorial blood assessment chart (PBAC) score, hemoglobin and serum ferritin levels, and endometrial thickness were assessed before insertion and during the follow-up visits. Results: Two patients (4.8%) were lost to follow-up, three patients (7.1%) opted for hysterectomy, two women (4.8%) experienced spontaneous expulsion and 35 (83.3%) women continued the usage. Menstrual blood loss assessed using the median PBAC score (interquartile range) significantly reduced (P < 0.001) from the pre-insertion level of 280 (246–306) to 124 (60–200) at 4 weeks to 45 (34–76) at 12 weeks and further to 32 (20–50) at the end of 24 weeks. Simultaneously, a significant (P < 0.001) improvement in the mean hemoglobin and serum ferritin levels and a significant (P < 0.001) decrease in endometrial thickness were observed. The most common side effect was spotting (50.0%) and vaginal discharge (38.1%).Conclusions: LNG-IUS causes a remarkable reduction in menstrual blood loss and marked improvement in dysmenorrhea. It also reduces anemia by improving the hemoglobin and ferritin levels. Thus, it can serve as an effective treatment option for heavy menstrual bleeding in perimenopausal women and prevent the need for a hysterectomy.

Nidhi Tyagi,Nidhi Sinha,Binay Kumar 한국물리학회 2014 Current Applied Physics Vol.14 No.2

The nonlinear optical single crystals of glycine sodium nitrate were grown by the slow evaporation method. XRD confirmed monoclinic structure. Thermal stability and melting point (225 C) were investigated. The dielectric behaviour of the crystals in the frequency range 20 Hze2 MHz at different temperatures is reported in which a ferroelectric to paraelectric phase transition at Tc ¼ 56 C is observed. The activation energies of GSN were found to be 3.615 eV, 0.593 eV and 0.0733 eV in three temperature regions of conductivity plot due to a hopping conduction mechanism. The crystal has shown high piezoelectric charge coefficient (d33) of 16 pC/N which is nearly double of observed value for gglycine single crystal. The spontaneous polarization Ps at room temperature was found to be 1.489 mC/ cm2 at applied maximum field of 26 kV/cm (1.194 mC/cm2 at 12 kV/cm) and the pyroelectric coefficient was determined to be 400 mC/m2/C. High value of squareness parameter (1.93) makes the GSN crystal suitable for switching applications. Detailed investigations of Ferro-/Piezoelectricity were observed for the first time in glycine sodium nitrate crystals which was found to preserve the ferroelectricity even after applying an electric field much higher than the saturation electric field (12e26 kV/cm). Application of GSN crystals as sensor, high power switch gears and storage memories has been established.

Adsorption and equilibrium studies of phenol and para-nitrophenol by magnetic activated carbon synthesised from cauliflower waste

Nidhi Yadav,Dhruv Narayan Maddheshiaya,Shalu Rawat,Jiwan Singh 대한환경공학회 2020 Environmental Engineering Research Vol.25 No.5

In this study, waste cauliflower leaves were used for adsorbent preparation. The waste cauliflower leaves were converted into activated carbon by pyrolysis at two different temperatures 250℃ and 500℃ with magnetic property. The prepared adsorbents were denoted as CAC-250 and CAC-500 and characterized by the use of scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The adsorbents were applied for the removal of phenol and PNP from their aqueous solutions. The adsorption of phenol was found very less by the application CAC-250, whereas by the application of CAC-500 the adsorption of both phenol and PNP was enhanced. The maximum adsorption of phenol was found 99% and that of PNP was found ~100% using CAC-500, with initial adsorbate concentration 5 ㎎/L at 25℃. The adsorption data was analysed with Langmuir, Freundlich and Temkin isotherm models and different kinetic models that are pseudo first order, pseudo second order, Elovich, intraparticle and pore diffusion model.

Diversity and seasonal fluctuations in dung beetle (Coleoptera) community in Kurukshetra, India

Nidhi KAKKAR,Sanjeev K. GUPTA 한국곤충학회 2010 Entomological Research Vol.40 No.3

Five pitfall traps baited with 150–200 g of fresh cattle dung were installed for 24 h at weekly intervals. A total of 991 dung beetles from 11 genera, 31 species and three subfamilies was obtained. The community was dominated by Oniticellus spinipes individuals by 32.3%. Ten species appeared only once during the collection period and species composition and dominance changed throughout the period. The overall pattern we detected in the organization of the dung beetle community is that the species richness, abundance and diversity rise in September and the 2nd week of October. The dung beetle community was found to be affected by season.

An Efficient Opportunistic Routing Protocol in Underwater Communication

Nidhi Rajpoot,Rajendra Singh Kushwah 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.6

For many years, opportunistic networks have gain fame in research and industry as a natural evolution of mobile ad hoc networks (MANETs). It is a more common concept of delay tolerant networks, which opens a thrilling path for connecting nodes opportunistically and communicates wirelessly and at the similar time expands the possibilities for real-life application problems. Presented ad hoc routing protocols, although robust to quickly changing network topology, suppose the being there of a connected path from source to destination. In this proposed system, we make a base station (BS1) on the upper layer of water. It is situated where signal strength is good. It will get the connection either by RSU (Road Side Unit) or by satellite. When it will get connected by RSU or satellite, sonar waves of base station amplifiers. Another base station (BS2) is situated under water at some distance from BS1 & gets radio waves by base station & its Sonar waves gets amplified.

Seasonal distribution and prevalence of dung beetles (Coleoptera: Scarabaeidae) in Kurukshetra, Northern India

Nidhi Kakkar 한국곤충학회 2010 Entomological Research Vol.40 No.6

A total of 8306 individuals as 29 species from 3 subfamilies (Hybosorinae, Aphodiinae, Scarabaeinae) were trapped by pitfall bait trapping. The maximum number of species of Scarabaeinae (68.97%) and number of individuals of Aphodiinae (56.84%) take part in the formation of a community. The number of species, number of individuals, diversity and dominance changes throughout the season. Seasonal prevalence of 82.76% of species and 50.81% of individuals was found in June. Aphodius campestris was found to be more attracted to the pitfall bait traps. The beetle community found in May shows the maximum Shannon's Diversity Index (2.46) but Margalef's Diversity Index was highest in August (3.06). Environmental factors play an important role in the occurrence and abundance of dung beetles. In the present study non-significant but positive correlations between temperature and species richness, abundance and diversity were found. Percent relative humidity showed a positive correlation with abundance only, and negative correlations with species richness and diversity.

Hydro-Priming Methods for Initiation of Metabolic Process and Synchronization of Germination in Mung Bean (Vigna Radiata L.) Seeds

Nidhi Shukla,Himani Kuntal,Asheesh Shanker,Satyendra Nath Sharma 한국작물학회 2018 Journal of crop science and biotechnology Vol.21 No.2

Seed priming is a commercially applied technique for improving seed vigor under variable field conditions. The present study was carried out to optimize the methods (direct: soaking in water 1:1 W/V and indirect: preconditioning under high RH ≥ 85%) and duration (hours)of hydro-priming, attempting to correlate the critical seed water content with priming-induced metabolic-restart in dry mungbean (Vigna radiataL.)seeds. Although the rate of water absorption and the amount of water absorbed was more by direct compared to the indirect imbibition method, the priming-induced germination responses were identical after 6hof priming treatment. The seed water content absorbed during this period was crucial for initiating the chain of biochemical events, required for early synchronized germination in primed seeds which was evident by improved membrane permeability, high activity of catalase and superoxide dismutase, and more integrated chloroplast and mitochondria in primed seeds. We demonstrate that the critical water content, required for priming-induced benefits for germination vigor, is a relative unit with respect to the duration of priming and the rate of water absorption. Seed priming is a co-ordinately regulated mechanism for controlling germination capacity of seeds by modifying the permeability characteristics of biological membranes and enzyme activity. This study helps to enhance our understanding on the potential of seed priming for synchronized germination and early seedling establishment in the field and beneficial for the resource poor farming community for better return of their limited financial/farm resources under variable environmental/field conditions.
