Ethibond suture in uterus: an unusual cause for secondary sterility

Failure to conceive two years after the LSCS, the patient was being investigated. Hysteroscopy revealed the presence of Ethibond suture in the uterine cavity attached to the lower part of the previous LSCS scar. The presence of this foreign body was acting as an intra-uterine contraceptive device responsible for failure of contraception. The presence of foreign body in the uterus such as bone pieces left after previous abortion, presence of suture of cervical circlage etc. have been reported. But the presence of Ethibond suture in the uterine cavity resulting in secondary sterility is being reported for the first time

FORMULATION DEVELOPMENT AND CHARACTERIZATION OF GASTRORETENTIVE DRUG DELIVERY SYSTEMS OF LORATADINE

Objective: The main objective of the research work is to develop a single unit non-effervescent drug delivery system of Loratadine (LTD) by direct compression process to prolong the gastric residence time (GRT). Methods: LTD non-effervescent tablets were prepared with different polymers like hydroxypropyl methylcellulose (HPMC) K15M, HPMC K100M (i.e.: 1:1, 1:2, 1:3) as release retardants. Glyceryl behenate (Compritol 888 ATO) and Glyceryl palmitostearate (Precirol ATO 5) were used (1:1, 1:2, 1:3) as low-density lipids to impart buoyancy for longer period. Results: The drug (LTD) and excipient (i.e. HPMC, low-density lipid aids, etc.,) interaction studies were carried out by Fourier Transform Infrared Spectroscopy (FTIR) and there was no likely interaction involving them. The developed LTD floating matrix tablets were characterized by pre and post-compression parameters and all results were, found within the pharmacopoeial limits. The cumulative percentage of drug release ranges from 56.87±0.25 % (F12) to 99.87±0.09 % (F2). The drug release profiles of the all formulations (F1 to F12) were subjected to various pharmacokinetic parameters and the optimized formulation (F3) followed the Korsmeyer Peppas (R2=0.996) model with non-Fickian diffusion (n>0.5). The obtained data by radiographic images of F3 formulation showed the GRT is 6±0.5 h (n=3). Conclusion: Hence, from all evaluation studies, it was evident that F3 formulation was optimized (99.82±1.63 % drug release in 12 h)

Design and Analysis of a Novel Low Complexity and Low Power Ping Lock Arbiter by using EGDI based CMOS Technique

Network-on-chip (NoC) provides solution to overcome the complications of the on-chip interconnect architecture in multi-core systems. It mainly consists of router, links and network interface. An essential component of on-chip router is an arbiter that significantly impacts the performance of the router. The arbiter should provide fast and fair arbitration when it is placed in Critical Path Delay (CPD) systems. The main aim of this research work is to design a novel arbiter for an effective network scheduler in complex real time applications. At the same time resource allocation and power consumption should be very low. Previously, a novel gate level Ping Lock Arbiter (PLA) is designed to overcome the limited fair arbitration in Improved Ping Pong Arbiter (IPPA) with less delay. But the chip size and power consumption are very high. To overcome this problem, an Effective Gate Diffusion Input (EGDI) logic based CMOS scheme is used to design a novel Compact Ping Lock Arbiter (CPLA).  The proposed CPLA is compared with the existing PLA based on static CMOS scheme. The comparison between the conventional and proposed arbiter is carried out to analyze the area, delay and power by using Tanner Tool 14.1 with 250nm and 45nm. The results show that the proposed NPLA achieves low power and consumes less than the existing ping lock arbiter

A Comprehensive Analysis of Literature Reported Mac and Phy Enhancements of Zigbee and its Alliances

Wireless communication is one of the most required technologies by the common man. The strength of this technology is rigorously progressing towards several novel directions in establishing personal wireless networks mounted over on low power consuming systems. The cutting-edge communication technologies like bluetooth, WIFI and ZigBee significantly play a prime role to cater the basic needs of any individual. ZigBee is one such evolutionary technology steadily getting its popularity in establishing personal wireless networks which is built on small and low-power digital radios. Zigbee defines the physical and MAC layers built on IEEE standard. This paper presents a comprehensive survey of literature reported MAC and PHY enhancements of ZigBee and its contemporary technologies with respect to performance, power consumption, scheduling, resource management and timing and address binding. The work also discusses on the areas of ZigBee MAC and PHY towards their design for specific applications

Coding Schemes for Distributed Storage Systems: Implementation and Improvements

Distributed data storage systems are used to store data reliably over a distributed collection of storage locations, called peers. Coding schemes are used to store a portion of the data in the peers ensuring the complete retrieval of data, during peer failures. This has applications in various areas like Wireless Networks, Sensor Networks etc. In this framework we consider a large file to be stored in a distributed manner over few peers of limited capacity. Each peer stores a portion of the coded data, without the knowledge of the contents of other peers. Random Coding is one of the coding schemes used for this. In [1] coding coefficients are chosen randomly from a finite field to encode the data. The encoding is basically a linear combination of file pieces (pieces are elements of finite fields). The data downloader downloads these coded data from several peers and decodes to get the original data. The decoding is basically solving a system of linear equations over a finite field, which is the most time consuming step in the whole process. We give a simple C++ implementation of the schemes in [1] and plot the results. We are trying to find a scheme where coding vectors can be chosen such that the decoding complexity is reduced significantly. Also in a dynamic setting where nodes enter and leave system intermittently, are discussed

కేజు సాగు కొరకు స్థలం ఎంపిక మరియు నీటి నాణ్యత (Site selection and water quality requirements for cage culture)

Site selection and water quality is one of the most important factors that determine construction costs, operating costs, production and mortality. Before establishing a cage culture site make sure the water body chosen will support the increased biological demand. This can be done by prior knowledge on the environmental/ hydro-biological parameters of the site or by conducting a field survey

కేజు సాగుకు చేపజాతుల ఎంపిక (Species selection for cage culture)

Interest in cage culture has been revived as an alternative crop for farmers outside traditional fish farming areas and in areas with topography not conducive to construction of ponds. The selection of the appropriate species of fish is necessary for the success of cage culture system. Species selected for farming in floating net-cages should meet the necessary criteria for being a cultivable species

Reproductive biology of the commercially important Uroteuthis (Photololigo) duvaucelii (d’ Orbigny [in 1835) off Mangalore, south-west coast of India

Uroteuthis (Photololigo) duvaucelii is one of the commercially important inshore squid resources off the south-west coast of India. Length-weight relationship for this species indicated no significant difference between the sexes and hence, the relationship for both the sexes was represented with the common equation W = 0.4624 L2.1158. U. (P.) duvaucelii spawned throughout the year with peak spawning in May. Absolute fecundity ranged from 1,545 to 13,585 eggs with an average of 7,554 eggs. Size at first maturity indicated that females matured earlier at 70 mm DML (dorsal mantle length) whereas males matured little later at 90 mm DML. Males were observed to be dominant during most of the study period with overall male to female ratio of 1:0.93. Seasonal and size dependent variations in sex ratio were distinct

Length-weight relationship of selected commercially important marine fishes from east coast of India

The paper deals with length-weight relationship (LWR) of selected commercially important marine fishes from the east-coast of India. Samples were collected fortnightly from experimental fishing using trawl operated at depth up to 70 M off Vishakhapatnam coast on the east-coast of India during 2015-17. Measurements of total length (TL) (nearest to 0.1 cm) and body weight (nearest to 0.1 g) of individual fish were taken. The LWR showed good fit with r2 values ranging from 0.975 for Lepturacanthus savala Cuvier, 1829 to 0.999 for Upeneus vittatus Forsskål, 1775. The ‘b’ values ranged from 2.618 for Photopectoralis bindus Valenciennes, 1835 to 3.186 for L. savala Cuvier, 1829

Sea erosion along the Andhra Pradesh coast

Andhra Pradesh with a coastline of around 974 km has frequently been affected by cyclones and inundated by storm surges. Sea erosion is noticed at Visakhapatnam, Bhimunipatnam and in the East and West Godavari districts. Vishakhapatnam coast is facing erosion since long specially at Ramakrishna Beach. In 2013 and 2014, the cyclones ‘Phailin’ and ‘Hudhud’ further hastened erosion of the Ramakrishna Beach, severely damaging the adjacent protection wall and road. Uppada village which is 22 kilometres away from Kakinada also faces severe erosion. The Kakinada-Uppada road is gradually disappearing due to shoreline erosion
