Functional outcome of mini external fixator in hand injuries: an observational study in a tertiary care hospital

Background: Metacarpal and phalangeal fractures are one of the common fractures of the upper extremity that account for about 10% of total body fractures. The distal parts of the hand are the most common parts to be injured. Outcome is also influenced by other factors such as patient’s age, occupation, socio economic status, systemic illness, surgeon’s skill and the patient’s compliance. Methods: We are doing an observational study with 40 patients included according to the inclusion and exclusion criteria for a period of six months with age group between 20 and 60 years. We use mini external fixators with JESS clamps, 1.8 mm threaded pins and k wires. Patients were followed up periodically with required radiograph for the union of the fracture. Results: Out 40 patients, most of the patients were between the age of 21 to 40 years with male preponderance, open fractures were more when compared with closed fractures. Functional outcome was excellent and good on the higher side which was analysed with Strickland score. Radiological union were also in greater side with 17.5% of them with delayed union. Conclusions: Simple surgical technique will minimize complications and an aggressive rehabilitation will ensure best result. In general, mini external fixator is a good treatment for management of fractures with best functional outcome.  

Weed anemone menace in marine aquaria and its management

Sea anemones are coming under the Phylum Cnidaria and Class Anthozoa. Like many Cnidarians, sea anemones contain specialized cells, known as cnidocytes or nematocytes, in their body column, oral disc, pharynx, tentacles and mesenterial filaments. Sea anemones of Aiptasia genus are distributed in temperate and tropical oceans attached to any hard substratum. The genus Aiptasia includes 13 species all equipped with 96 tentacles which are filled with nematocysts to sting their prey. The name Aiptasia itself means ‘beautiful’, however in marine aquarium keeping even if few Aiptasia are found in the tank it should not be taken so lightly. A hardy species it can explode in numbers within weeks. Aiptasia is a zooxanthellate anemone and survives well in the illuminated marine aquarium due to the photosynthetic activity of its algal symbiont

Background: Pregnancy influenced issues are common among pregnant women treated by medications that causes complication in mother and fetus. The study aims to identify patients with pregnancy influenced issues like gestational diabetes mellitus, gestational hypertension, gastroesophageal reflux disease and anaemia. To assess the drug used pattern along with antibiotic therapy and to observe the above disease related complications.Methods: A hospital based prospective observational study was conducted at department of obstetrics and gynecology in Rajah Muthiah Medical College and Hospital. Totally 100 patients enrolled and data was collected using data collection form.Results: Out of 100 patients, high prevalence occurred in 26-30 years of age. Primarily gestational hypertension (39%), treated with Tab. Labetatol and complications were premature delivery, low birth weight. Anaemia (25%) cases treated with Tab. Ferrous sulphate, Iron sucrose and Folic Acid, Preterm delivery as complication. Gestational diabetes mellitus (18%) treated with Metformin and Human Insulin and complications were preterm delivery, maternal obesity, increased child weight. GERD (8%) treated with Pantoprazole, Ondansetron, Bifilac and complications were weight loss, dehydration, low birth weight. In pre-operative cases, 79% received antibiotics as monotherapy and 21% as dual therapy. In post-operative cases, 41% received antibiotics as monotherapy and 59% as dual therapy. Metronidazole (95%) given in both post and pre- operative conditions.Conclusions: The present study provides valuable insight about the overall drugs used in pregnancy related diseases and complications arise. We hope our data will make necessary recommendations to all health care professionals and pregnant women to ensure all pregnancy related safety measures were taken

End-to-end security in embedded system for modern mobile communication technologies

Modern mobile electronic devices such as smartphones or cell phones can now be used for distant devices such as technical systems to monitor and control. While surveillance systems do not require high standards navigating about the time of transfer of the displayed data. More real-time data are needed for a remote mobile robot transfer. Therefore, it has investigated and measured not only the possibilities of employing mobile devices. But also, the supported data transmission channels, such as UMTS, GSM, Wireless LAN, and Bluetooth. The remotecontrol system is used in many applications such as smart homes, cities, smart hospitals, etc., but it must be today updated to ensure fast-changing technology. Extensive coverage, remote control, and reliable operation in realtime in the deployment of wireless security knowledge. The home automation control system delivers significant features together with a user-friendly interface. A secure remote-based end-to-end security system NTMobile, a technique that enables NAT to provide transverse and encrypted communication from end to end. This confirmed that evaluating the performance of the system in the ECHONET lite compatible smartphone ecosystem. This gives flexibility in configuring time-sensitive industrial networks and enables them to be secured. A safe and reliable remote-control system is also conceivable under the privacy of the user

Providing Consistency in Cloud Using Read after Write Technique to Endusers

ABSTRACT: A cloud service provider maintains multiple replicas for each piece of data on geographically distributed servers. In Existing system ,there occurs conflict in shared files,if one member in the group opens the file and editing or do some operations,if another member in the group opens and modifies the same file which is being used by another one then there occurs a conflict. In existing the algorithm used is HAS,heuristic auditing strategy but in proposed we are following Read-after-write consistency allows you to build distributed systems with less latency. As touched on above, without read-after-write consistency you'll need to incorporate some kind of delay to ensure that the data you just wrote will be visible to the other parts of your system

Operation and modelling of an updraft long-stick wood gasifier

Even though biomass gasification technology has come up in the past with impressive applications, the exact details of the gasification process are yet to be completely understood quantitatively. On the basis of the experience of gasifier users with regard to the efforts and energy needed for wood chip preparation in a typical gasifier, we have embarked on the development of a gasifier suitable to work with long-stick woody biomass as the feed material to avoid major fuel preparation problems in rural settings. With this concept, a 25m 3 /hr capacity updraft gasifier was designed and constructed. Since the interest here is in exploring and validating this concept, an updraft gasifier was designed. This gasifier attains a high-energy release rate per unit area due to high inlet air velocity and activated reaction in the combustion zone. The temperature ranged from 922º C in the combustion zone to 128º C in the drying zone. In all the zones, the heat balance equations show a good fit between the theoretical and experimental values. The gasifier was operated in a batch mode, both bottom-lit (conventional) and top-lit, and the air flow and gas outflow were measured. The temperature of the raw gas was measured. The gas and air flows can be converted to the air/fuel ratio (A/F), the most important aspect of gasifier operation. A/F shows operation in a combustion mode at start-up, a gasification mode for the middle part of the run and a charcoal gasification mode at the end of the run. For modelling, the gasifier was divided into a drying zone, a pyrolysis zone, a combustion zone and a reduction zone

Partial pressure of carbon dioxide (pCO2) and air-water CO2 exchange in the tropical semidiurnal estuarine system

Time-series observations of the Vellar estuary between May 2013 and December 2019 showed clear variability with respect to space and time in the distribution of nutrients, partial pressure of carbon dioxide (pCO2) and air-water CO2 exchange. Lower and higher salinities revealed significant seasonality in estuarine pCO2, as well as variations in the seasonal pattern due to the freshwater discharges during monsoon rainfall. The pCO2 attained the highest levels (8457 µatm) during monsoon which coincided with the lowest pH (7.498) and the undersaturation of pCO2 (322 µatm) was observed with maximum pH (8.182) during pre-monsoon. The Principal Component Analysis (PCA) identified four components that accounted for 77.28 % of the total variance and explained the significant influence of nutrients, chlorophyll and temperature on pCO2 distribution. Similarly, the multiple linear regression analysis showed significant influence of environmental variables on pCO2 variability with a R2 of 0.957, SEE±230.816, p < 0.001. The surveyed area of the Vellar estuary had an overall pCO2 of 1068 µatm and was supersaturated with regard to the atmospheric pCO2 throughout the year, with an average CO2 flux of 4.13±5.59 mmol C m-2 d-1 to the atmosphere. During the study period, the Vellar estuary actively supplied 650.2 mol C m-2 Y-1 to the atmosphere. Hence, the metabolic balance of the estuarine ecosystem is aided by land derived organic carbon accompanied with freshwater flows from the Vellar river, constituting the estuary as a substantial source of atmospheric CO2
