Calcium Hardness Analysis of Water Samples Using EDXRF Technique
Calcium hardness of water samples has been determined using a method based upon the energy Dispersive X-ray fluorescence (EDXRF) technique for elemental analysis. the minimum detection limit for Ca has been found in the range 0.1-100ppm. the experimental approach and analytical method for calcium studies seem satisfactory for the purpose and can be utilized for similar investigations
Headache and seizure on postpartum day 7: late postpartum eclampsia: a case report
Historically, convulsions beginning more than 48 hours, but less than 4 weeks, after delivery, known as late postpartum eclampsia, was thought to be uncommon; however, recent evidence suggests that its incidence is increasing. In addition, the presentation of late postpartum preeclampsia-eclampsia may differ from that occurring during the pregnancy. About 40% of late eclampsia has no premonitory symptoms. This contributes to difficulty in diagnosing late postpartum preeclampsia-eclampsia in an emergency department setting. Greater awareness and knowledge of this disorder by ED physicians should improve outcomes in these potentially life-threatening cases. The authors present a case of new-onset seizures occurring 07 days postpartum. The patient presented with headache, hypertension, and generalized tonic-clonic seizures to the emergency department. Postpartum eclampsia was diagnosed and IV magnesium sulphate was administered. The patient had no further seizures and did not require long-term anticonvulsants.

Relationship of lunar phases and sex of the foetus: a retrospective study
Background: The relation of lunar phases at the time of conception to the sex of the child at birth has been touted as a method of sex selection by various birth calendars with controversial results. It is made to believe that indeed there is a relation of lunar phase at the time of conception/intercourse which results in birth of a particular gender. The purpose of this study was to examine the influence of the lunar phase on the possible relationship between lunar position at EDD/LMP and the gender of the child.Methods: One thousand and five deliveries were retrospectively analysed from 1 January 2016 to 31 December 2018 at the department of obstetrics and gynaecology of military hospital, Gwalior (latitude and longitude coordinates: 26.218287, 78.182831). Females having regular menstrual periods history around conception and in general their periods have been normal and regular were included in the study. Females having irregular menstrual periods history or having oligomenorrhoea/polymenorrhoea, ART/IVF conceptions were excluded from the study. Exact lunar phases were determined at the time of EDD and not with their LMP since that would automatically corelate well with LMP because of regularity of their periods. The actual date of birth was not considered while corelating with moon phase because of obvious reason of unexpected timing of labour.Results: The analysis revealed no significant correlation of gender of the child to lunar phases at EDD. This would indirectly corelate well with the LMP since the inclusion criterion had females having normal and regular menstrual periods.Conclusions: There is no predictable influence of the lunar phase on the gender of the baby. As expected, and in agreement with some recent studies this pervasive myth is not evidence based
Landslide susceptibility mapping using certainty factor, index of entropy and logistic regression models in GIS and their comparison at Mugling-Narayanghat road section in Nepal Himalaya.
Landslide susceptibility maps are vital for disaster management and for planning development activities in the mountainous country like Nepal. In the present study, landslide susceptibility assessment of Mugling–Narayanghat road and its surrounding area is made using bivariate (certainty factor and index of entropy) and multivariate (logistic regression) models. At first, a landslide inventory map was prepared using earlier reports and aerial photographs as well as by carrying out field survey. As a result, 321 landslides were mapped and out of which 241 (75 %) were randomly selected for building landslide susceptibility models, while the remaining 80 (25 %) were used for validating the models. The effectiveness of landslide susceptibility assessment using GIS and statistics is based on appropriate selection of the factors which play a dominant role in slope stability. In this case study, the following landslide conditioning factors were evaluated: slope gradient; slope aspect; altitude; plan curvature; lithology; land use; distance from faults, rivers and roads; topographic wetness index; stream power index; and sediment transport index. These factors were prepared from topographic map, drainage map, road map, and the geological map. Finally, the validation of landslide susceptibility map was carried out using receiver operating characteristic (ROC) curves. The ROC plot estimation results showed that the susceptibility map using index of entropy model with AUC value of 0.9016 has highest prediction accuracy of 90.16 %. Similarly, the susceptibility maps produced using logistic regression model and certainty factor model showed 86.29 and 83.57 % of prediction accuracy, respectively. Furthermore, the ROC plot showed that the success rate of all the three models performed more than 80 % accuracy (i.e. 89.15 % for IOE model, 89.10 % for LR model and 87.21 % for CF model). Hence, it is concluded that all the models employed in this study showed reasonably good accuracy in predicting the landslide susceptibility of Mugling–Narayanghat road section. These landslide susceptibility maps can be used for preliminary land use planning and hazard mitigation purpose
A General Survey on Rushing Attack in MANETs
MANETs (Mobile Ad hoc Network) is a kind of network in which all the nodes are connected via wireless link. There is no fixed infrastructure because of which any node can join or leave the network at any point time. There is no central monitoring system. All the nodes are working as host as well as client at the same time. This makes the network vulnerable to different kind of attacks. Standard routing protocols are also not that secured to protect the network from all probable attacks. Attacker may attack the network and disrupt the network services abruptly. Some of the common attacks in MANETs are Rushing attack, Black hole attack, Sybil attack, Neighbor attack and Jellyfish attack etc. In this paper we are trying to accumulate different probabilities of getting rushing attack in MANETs. And also discuss about different counter measures to prevent as well as to detect rushing attack.Keywords:Rushing attack, MANETs, Security, Denial of Service (DoS), Security threat
A large fibroma polyp of labia majora
Fibroepithelial stromal polyps are benign proliferations which are usually polypoid or pedunculated, and less than 5cm in size. They are generally single lesions but can be multiple during pregnancy. They can be polypoid or pedunculated and are usually solitary. Symptoms usually include bleeding, discharge and general discomfort with sensation of a mass. They typically have a central fibrovascular core and contain stellate and multinucleated stromal cells which are best seen beneath the surface epithelium. True myxoid stroma is absent. Although vulvovaginal fibroepithelial stromal polyps are well documented, a giant variant such as the one authors report here is rather rare. To the knowledge, present case is the largest fibroepithelial stromal polyp compared to others reported in the literature
Misplaced IUCD: a case report
Contraception is a national emergency, essential in a developing country like India. Intrauterine contraceptive devices (IUCDs) are amongst the most frequently used methods of contraception. The patients with misplaced IUCDs may present with pregnancies or ‘lost strings’ or they may remain asymptomatic and/ or may have recurrent pregnancy losses and may become pregnant as in our case
An update of electro surgery devices options in minimal invasive surgery: a review
The rate and variety of advances in energy sealing technology in the last two decades has heralded new opportunities in laparoscopic and minimally invasive surgery. Reduced operating times, lower postoperative pain scores, and shorter length of stay are offset by the additional cost of such instruments. Critical to obtaining optimal clinical effects and reducing potential complications, is a thorough understanding of the proper use of each energy modality. No single device has shown a significant superiority over the other. However best combination to have is harmonic along with ligasure or perhaps now the latest wireless sonicision with ligasure to undertake most of the surgeries. Thunderbeat has advantages like faster cutting speed and minimal instrument changes. Ferromagnetic wand is the fastest available instrument with unique features. Argon beam coagulation has certain specific uses and is best for fulguration and it is definitely advantageous to have it in OT. Sonicision offered wireless ergonomics and better manoeuvrability, cheapest VSD was the conventional bipolar
Effect of rock weathering, clay mineralogy, and geological structures in the formation of large landslide, a case study from Dumre Besei landslide, Lesser Himalaya Nepal
The Dumre Besi landslide is one of the largest and most problematic failures on the Mugling-Narayanghat Highway in central Nepal. Though it was triggered by the monsoon rain of 2003, geological structures and rock weathering have played a key role in its initiation and further aggravation. The slide is also controlled to some extent by the groundwater and rugged topography with high slope angles. The landslide zone comprises thinly laminated light grey siltstone with numerous crosscutting quartz veins, grey metasandstone (quartzite), bluish grey to white phyllite, black carbonaceous slate, and dolomite. A thrust fault passes through the centre of the landslide, creating a thick deposit of loose, weathered rock material, and the fault has developed a very thick shattered zone where weathering is very intense. Using field and laboratory analyses, the rocks in the landslide zone can be divided into five zones based on the severity of weathering: none, slight, moderate, severe, and complete. Laboratory analyses showed that the chemically weathered rocks are significantly rich in smectite and vermiculite. Out of these, smectite is the most critical one, as it swells when wet. The formation mechanism of the clay minerals was analysed by various techniques, including X-ray diffraction, X-ray fluorescence, and thin-section analysis, and it was found that most of them were derived from weathering of rock. The clay minerals significantly reduced the rock strength and facilitated the extensive failure of Dumre Besi. The wide fault zone with deeply weathered and clay-rich debris is also responsible for the formation of debris flows in the monsoon season.ArticleLANDSLIDES. 10(1):1-13 (2013)journal articl
