Rupture of non-communicating horn of a bicornuate uterus

A primigravida at 20 weeks GA was referred as a case of bleeding P/V with an USG report showing intra-uterine foetal demise. Accordingly we induce her with misoprostol followed by ethacrydine lactate but there was no progress. On repeat USG here we saw there was rupture of a horn of uterus with abortus free in peritoneal cavity. On laparotomy there was 1 litre of hemoperitoneum with abortus lying free inside. There was rupture of a non-commnicating horn of a bicornuate uterus which was excised and uterine wall repaired

A Study on Genotoxic Potential of Acephate in Clarias batrachus

Acephate is an insecticide made up of organophosphates. It is applied to food crops, citrus trees, on golf courses, in commercial or institutional buildings, and as a seed treatment. Products containing acephate can be purchased as tablets, liquids, granules, powders, and water-soluble packs. Acephate 75% brand name-Asataf insecticide manufactured by TATA RALLIS was used for the test. The solvent used was glass double distilled (g.d.d.) water. Fresh water catfish    Clarias batrachus were collected from local water bodies of Cuttack district. All the fishes were acclimatized for fifteen days in laboratory aquaria containing 30L dechlorinated tap water prior to the initiation of the experiment. The peripheral blood smear slides were prepared from the blood collected by caudal incision in accordance with Al-Sabti (1986) and Das and Nanda (1986) with some modifications which were prepared animals were sacrificed after 24, 48 and 72 hours of Exposure and were used for each treatment group in both types of administrations (IP and dermal). The increased concentration of acephate directly affects our biological fish sample i.e. Clarias batrachus. Acephate is causing serious problems in fish as per our genotoxicity study of acephate on Clarias batrachus. Clarias batrachus is a commonly found fish species in fresh water habitat which includes ponds, ditches, wetlands and rice fields of India specially in Odisha.The irrational use of pesticides containing acephate in agriculture cause harmful effects on Clarias batrachus, which is a most important species of fish for maintaining the aquatic diversity

A rare case of broad ligament pregnancy diagnosed at 36 weeks of gestation incidentally during laparotomy

Pregnancy in the broad ligament is a rare form of ectopic abdominal pregnancy with a high risk of maternal mortality. Ultrasound examination may help in the early diagnosis but mostly the diagnosis is established during surgery. We are reporting a case of broad ligament pregnancy diagnosed incidentally during laparotomy. She had uneventful postoperative recovery.

EVALUATION OF SERUM NITRIC OXIDE IN ESSENTIAL HYPERTENSION AND ITS CORRELATION WITH SEVERITY OF DISEASE

ABSTRACTObjective: Hypertension is the most common cardiovascular disease and one of the most important public health concerns all over the world. Primaryor essential hypertension is the major form of arterial hypertension without any definitive cause. It results from increase vascular tone and resistancewhich may be confined to the lower level of endothelial derived relaxing factor such as nitric oxide (NO). Hence, the objective of this study is to findout whether any correlation exists between the concentrations of serum NO (nitrite) and essential hypertensive patients categorized according to theJoint National Committee 7 classification.Methods: We selected age- and sex-matched 24 healthy individuals as controls and 35 essential hypertensive patients as cases. Out of 35 cases, 24were included in stage 1 and 11 in stage 2 of essential hypertension. We estimated serum NO levels in study groups basing on the principle of Griessreaction.Results: We observed reduction in mean serum NO level in cases which was statistically highly significant as compared to controls (8.14±0.33 vs.13.53±0.38 µmol/L, p<0.001) and also in stage 2 patients when compared with stage 1 patients (5.97±0.31 vs. 9.15±0.28 µmol/L, p<0.001). Inhypertensive patients, serum NO showed a highly significant inverse correlation to both systolic (r=−0.89, p<0.001) as well as diastolic (r=−0.64,p<0.001) blood pressure.Conclusion: Thus, we can conclude that lower level of serum NO can be an important causative factor in the progress of essential hypertension.Keywords: Essential hypertension, Endothelial-derived relaxing factor, Nitric oxide, Joint National Committee 7

Machine Learning-Based Cooperative Spectrum Sensing in A Generalized α-κ-μ Fading Channel

An improvement in spectrum usage is possible with the help of a cognitive radio network, which allows secondary users’ access to the unused licensed frequency band of a primary user. Thus, spectrum sensing is a fundamental concept in cognitive radio networks. In recent years, Cooperative spectrum sensing using machine learning has garnered a great deal of attention as a technique of enhancing sensing capability. In this study, K-means clustering is taken into consideration for the purpose of analyzing the effectiveness of cooperative spectrum sensing in a generalized α-κ-μ fading channel. The proposed approach is examined using receiver operating characteristic curves to determine its performance. The effectiveness of the proposed strategy is contrasted with that of the existing detection techniques such as Cooperating spectrum sensing based on energy detection and OR-fusion-based cooperative spectrum sensing for fading channels κ-μ, α-κ-μ. As demonstrated by results, the proposed method outshines an existing method in terms of comparison parameters, as determined by simulation results in the MATLAB version

An Investigation Of Cloud Processes Relevant To Climate Sensitivity

Based on the Fourth Assessment Report of the IPCC, cloud feedbacks are the largest source of uncertainty in predicting the Earth's climate response to CO2 radiative forcing. Various global climate models estimate that this response amplifies the initial CO2 forcing by a factor between 2 and 5. The research in this dissertation aims to better understand cloud processes that have been identified as critical for understanding cloud feedbacks. The three topics pursued are characterization of the ice fall speed in cirrus clouds, ice nucleation in cirrus clouds and ground-based remote sensing of cloud properties in ice clouds and mixed phase clouds.Studies have shown that the ice fall speed determines one of the most important climate feedback processes. The mass weighted ice fall speed (Vm) in mid-latitude cirrus clouds is computed from in-situ measurements of ice particle area and number concentration by the 2 Dimensional Stereo (2D-S) probe. Vm is parameterized in terms of cloud temperature (T) and ice water content (IWC) and also by relating Vm to ice particle effective diameter (De). Mid-latitude cirrus cloud data is also used to investigate two classes of ice nucleation: homogeneous and heterogeneous processes. Better understanding the role these two categories play in ice production is crucial for predicting cirrus cloud properties and the impact of aerosol particles on cirrus clouds in GCMs. The temperature dependence of the ice particle size distribution, number concentration-to-ice water content ratio, ice particle shape and fall speed all provide important clues revealing the relative roles of these nucleation categories.Lastly an exploratory remote sensing methodology is presented to retrieve cloud properties in ice clouds and mixed-phase clouds by using data from the Atmospheric Emitted Radiance Interferometer (AERI) and the Milli-Meter Cloud Radar (MMCR) in the Arctic

Variations in hydro-chemical properties and source insights of coalbed methane produced water of Raniganj Coalfield, Jharkhand, India

The production of coalbed methane is increasing rapidly in Raniganj coalfield of India. The present statistics of methane gas production and produced water is about 1.7 mmscmd (million metric standard cubic meter per day) and 12160 m3/day respectively from 560 CBM wells. The major concerns are challenges related to CBM produced water treatment, it's handling, uses for various purposes and its proper disposal is yet to be resolved, considering physico-chemical parameters, socio-economic, environmental and techno-commercial aspects. In view of this, a detailed study of CBM produced water of Raniganj coalfield has been carried out to evaluate hydro-chemical variations, quantity, quality, related aquifer characteristics, options of treatment, suitable beneficial uses and disposal. The large amount of TDS is the major concern contributed by cations andanions like Na+, Ca2+ and HCO3−. The trace metal content obtained through Inductively Coupled Plasma Mass Spectrometry (ICPMS) analyses such as Fe2+, Mn2+, Zn2+, Sr2+and Al3+ varies from 0.12 to 0.94, 0.002 to 0.651, 0.001 to 0.041, 0.005 to 0.801 and 0.002–0.092 mg/l respectively. Atomic absorption spectroscopy (AAS) was used for cations (Na+, K+, Mg2+ and Ca2+) distribution found ranged from 289 to 1136, 0.00 to 0.94, 0.18 to 1.82 and 10.2–21.2 mg/l respectively, whereas, anions (SO42−, F−, Cl−, NO3− and HCO3−) were determined using Ion Chromatography (IC), found varying from 0.14 to 1.62, 1.042 to 4.862, 114.42 to 565.21, 7.41 to 70.4 and 1923.4–3129.4 mg/l respectively. The CBM produced water is classified as Na+–K+–CO32-–HCO3- and Na+–HCO3- type attributed to different rock formations of aquifers and deeper coal seams. TDS and trace metals concentrations are controlled by depositional environment, local marine transgression occurred during the Sakmarian - Artinskian geological period and inherited from groundwater mineral interactions. The results of proposed model for quality parameter prediction signifies TDS content is observed to be low during the initial five years of production and gradually increases with time. The similar trend is shown by HCO3−, Na+, SO42−, F−, Cl− and NO3− signifying the rock interaction and alterations is the only source of minerals and ions. Initially, the shallow aquifer water having interaction with fresh water recharge dilutes the concentrations of different water quality parameters, but as production continues, the concentration of constituents directly controlled by formation rocks and may increase until it reaches the saturation point. The continuous drawdown of water from a large number of CBM wells changing the regional static hydrological balance including a drainage system and it may take long spells to recuperate its original levels. This study can be utilized in designing treatment processes, beneficial uses and exploring the new water resources in Raniganj coalfield
