Survey on Network Coding for Multiple Cloud Storage

Reliability of data can be provided by maintaining redundancy in multiple cloud storage nodes. The simplest form of providing redundancy is replication, where it involves directly replicating data to multiple clouds. However, replication technique involves high computational cost and monetary cost is high when retrieving data in the multiple cloud environments. Therefore, striping data across multiple cloud storage is one of the best solution for providing redundancy and repair cost is very less when compared to replication. There exists many codes, which performs striping of data, erasure coding is an example where provides good redundancy. However, the erasure codes perform recovery of whole file rather a single block. Therefore new design problem arises when erasure codes are used. However, regenerating codes shows better solution for this problem. DOI: 10.17762/ijritcc2321-8169.15031

In vitro shoot multiplication and conservation of Caralluma bhupenderiana Sarkaria - an endangered medicinal plant from South India

An efficient protocol was described for the rapid in vitro multiplication of an endangered medicinal plant, Caralluma bhupenderiana Sarkaria, via enhanced axillary bud proliferation from nodal explants collected from young shoots of six-months-old plant. The physiological effects of growth regulators [6- Benzyladenine (BA), kinetin (Kn), 2-Isopentyl adenine (2iP), zeatin (Zn), indole-3-acetic acid (IAA), indole-3-butyric acid (IBA)], different strengths of Murashige and Skoog (MS) medium and various pH levels on in vitro morphogenesis were investigated. The highest number (8.40 + 0.50) of shoots and the maximum average shoot length (3.2 ± 0.31 cm) were recorded on MS medium supplemented with BA (8.87 μM) at pH 5.8. Rooting was best achieved on half-strength MS medium augmented with NAA (2.69 μM). The plantlets regenerated in vitro with well-developed shoot and roots were successfully established in pots containing peat mass and garden manure in 1:1 ratio and grown in a greenhouse with 80% survival rate. The regenerated plants did not show any immediate detectable phenotypic variation.Key words: Apocynaceae, asclepiadoideae, conservation, micro-propagation, endangered, Caralluma bhupenderiana

The missing intrauterine device

The Intrauterine Contraceptive Device (IUD) is an acceptable and common form of contraception worldwide. The objective of this study was to report the case of an asymptomatic missing intrauterine contraceptive (IUD) inserted to prevent intrauterine adhesions after synechiolysis. A patient presented with missing IUD threads. Ultrasound of the pelvis showed an empty uterine cavity with the missing IUD probably anterior to the uterus. We present a stepwise approach in the management of the “lost IUD”, where the strings of the device are not visible at the time of speculum examination. We suggest first determining sonographically whether the IUD is within the cavity. If it is in situ, options for retrieval are including hysteroscopic retrieval. If the IUD is not within the cavity, X-rays are recommended. The device will not be present on X-ray if expulsion has occurred. If the device is present on the X-ray, cystoscopic or laparoscopic retrieval is required. IUD-providers should not only screen potential users and insert IUD correctly, but also ensure adequate follow-up with localization

AmnioQuick® Duo+ for diagnosis of premature fetal membranes rupture

Background: Failure to identify women with premature fetal membranes rupture associated with infectious morbidities. Evaluation of the accuracy of AmnioQuick® Duo+ in diagnosing premature fetal membranes rupture compared to conventional diagnostic tests was the aim of this study.Methods: 220 pregnant women ≥37 and <39 weeks` gestation studied and classified into two groups; study group (premature fetal membranes rupture) and control group (no premature fetal membranes rupture). Participants examined by trans-abdominal ultrasound (TAS) and vaginal speculum to visualize amnion leaking and for collection of samples for fern, nitrazine and AmnioQuick® Duo+ tests on admission. A final diagnosis whether the studied women had PROM or not at the initial presentation made after delivery.Results: Sensitivity and specificity of the AmnioQuick® Duo+ to diagnose PROM was 93.6% and 86.4%; respectively compared with 72.7% and 80.9%; respectively for fern test and 76.4% and 83.6%; respectively for nitrazine test. Positive predictive value, negative predictive value and accuracy of AmnioQuick® Duo+ to detect PROM were 87.3%, 93.1% and 90%; respectively compared with 79.2%, 74.8% and 76.8%; respectively for fern test and 82.4%, 77.97% and 80%; respectively for nitrazine test. AmnioQuick® Duo+ test had higher accuracy to detect premature fetal membranes rupture compared to conventional diagnostic tests.Conclusions: AmnioQuick® Duo+ is accurate bedside immunoassay test, better than the individual conventional diagnostic tests and can used as complementary test to improve the management of women with women premature fetal membranes rupture

Drought tolerance in MnSOD transgenic Hevea brasiliensis in a dry sub-humid environment

One year old bud-grafted plants of MnSOD transgenic Hevea lines (L1 and L2) and an untransformed line of clone RRII 105 were used in the present study to evaluate their physiological performance in a dry sub-humid environment by withholding irrigation and to assess the recovery by re-watering. The dry matter partitioning was more towards the root in transgenic lines (55% and 60% in Ll and L2, respectively) but, was less in the untransformed RRII 105 (43%). After six days of moisture stress in polybags, pre-dawn leaf water potential and relative water content declined in all the lines, however, transgenic line L1 showed higher tissue water content throughout the drought as well as recovery period. Chlorophyll content did not show any significant reduction. Net photosynthetic rate (PN) declined rapidly and it reached near zero on the third day of drought imposition except for line L1, which showed lesser decline in PN. The decline in stomatal conductance (gs) was more rapid than PN in all the lines. On re-watering, recovery of PN and gs was better in the transgenic lines than untransformed RRII 105, which did not recover fully from the drought impact. Antioxidant enzymes, superoxide dismutase and peroxidase did not show a definite trend in their activities in these lines. However, it was found that the transgenic line L1 had better drought tolerant capacity in terms of lesser inhibition of photosynthetic rate under drought and faster recovery on re-watering

Innovative programme for creating entrepreneurs: Success stories in sea food micro enterprises

Krishi Vigyan Kendra (Ernakulam) formulated a special training programme with an intention to create micro -sea food entrepreneurs. There was no stipulated time for the training programme, instead it continued till the selected entrepreneurs become successful. Follow up services are also being given to the successful entrepreneurs. Selection of the trainees was based on their accessibility to the raw material and availability of space for processing, packing and forwarding. The programme covered all aspects of initiating a sea food enterprise. The syllabus covered selection of good quality raw fish at a cheaper price from the auctioning centers near Kochi. The first lesson was to learn the process of fish auctioning. Subsequently, the candidates were trained in the transportation of bulk quantity of fish without quality degradation followed by temporary storage and scientific cutting and cleaning. Selection of quality additives like spices, oil etc. in bulk quantities in cheaper price and their storage were covered. Introduction of processing gadgets, labor & time management, product formulation, packing, attractive label designing, designing of trademark, registration of trademark, the importance of branding etc. were covered. In addition, the statutory licenses and certificates required for the industry and step by step procedure to obtain the same were also included in the syllabus. Tie-ups were made with retail marketing outlets and test marketing of the products were done by the participating trainees. Methods in finding out the marketing channels and waste utilization were also covered. Two entrepreneurs started products under their own brand name. The products are fish pickle, squid pickle, dry prawn roast, prawn chutney powder and ready to cook dry prawn. One entrepreneur started exporting dry prawn products and prawn wafers

Mental illness, poverty and stigma in India: a case-control study

Objective: To assess the effect of experienced stigma on depth of multidimensional poverty of persons with severe mentalillness(PSMI) in Delhi, India, controlling for gender, age and caste. Design: Matching case(hospital)–control(population) study. Setting:University Hospital (cases) and National Capital Region (controls),India. Participants: A case–control study was conducted from November 2011 to June 2012. 647 cases diagnosed with schizophreniaor affective disorders were recruited and 647 individuals of same age,sex and location of residence were matched as controls at a ratio of 1:2:1. Individuals who refused consent or provided incomplete interview were excluded. Main outcome measures: Higher risk of poverty due to stigma among PSMI. Results :38.5% of PSMI compared with 22.2%of controls were found poor on six dimensions or more. The difference in multidimensional poverty index was 69% between groups with employment and income of the main contributors. Multidimensional poverty was strongly associated with stigma(OR 2.60,95%CI 1.27 to 5.31) ,scheduled castes/scheduled tribes/other backward castes(2.39,1.39 to 4.08),mental illness (2.07,1.25 to 3.41)and female gender(1.87,1.36 to 2.58).A significant interaction between stigma,mental illness and gender or caste indicates female PSMI or PSMI from ‘lower castes’ were more likely to be poor due to stigma than male controls(p\u3c0.001)or controls from other castes(p\u3c0.001). Conclusions: Public stigma and multidimensional poverty linked to SMI are pervasive and intertwined.In particular for low caste and women,it is a strong predictor of poverty.Exclusion from employment linked to negative attitudes and lack of income are the highest contributors to multidimensional poverty,increasing the burden for the family. Mental health professionals need to be aware of and address these issues

A novel hybrid password authentication scheme based on text and image

Considering the popularity and wide deployment of text passwords, we predict that they will be used as a prevalent authentication mechanism for many years to come. Thus, we have carried out studies on mechanisms to enhance text passwords. These studies suggest that password space and memorability should be improved, with an additional mechanism based on images. The combination of text and images increases resistance to some password attacks, such as brute force and observing attacks. We propose a hybrid authentication scheme integrating text and recognition-based graphical passwords. This authentication scheme can reduce the phishing attacks because if users are deceived to share their key passwords, there is still a chance to save the complete password as attackers do not know the users' image preferences. In addition to the security aspect, the proposed authentication scheme increases memorability as it does not require users to remember long and complex passwords. Thus, with the proposed scheme users will be able to create strong passwords without sacrificing usability. The hybrid scheme also offers an enjoyable sign-in/log-in experience to users

Implementation and evaluation of the Helping Babies Breathe curriculum in three resource limited settings: does Helping Babies Breathe save lives? A study protocol

Background: Neonatal deaths account for over 40% of all under-5 year deaths; their reduction is increasingly critical for achieving Millennium Development Goal 4. An estimated 3 million newborns die annually during their first month of life; half of these deaths occur during delivery or within 24 hours. Every year, 6 million babies require help to breathe immediately after birth. Resuscitation training to help babies breathe and prevent/manage birth asphyxia is not routine in low-middle income facility settings. Helping Babies Breathe (HBB), a simulation-training program for babies wherever they are born, was developed for use in low-middle income countries. We evaluated whether HBB training of facility birth attendants reduces perinatal mortality in the Eunice Kennedy Shriver National Institute of Child Health and Human Development’s Global Network research sites. Methods/design: We hypothesize that a two-year prospective pre-post study to evaluate the impact of a facility-based training package, including HBB and essential newborn care, will reduce all perinatal mortality (fresh stillbirth or neonatal death prior to 7 days) among the Global Network’s Maternal Neonatal Health Registry births ≥1500 grams in the study clusters served by the facilities. We will also evaluate the effectiveness of the HBB training program changing on facility-based perinatal mortality and resuscitation practices. Seventy-one health facilities serving 52 geographically-defined study clusters in Belgaum and Nagpur, India, and Eldoret, Kenya, and 30,000 women will be included. Primary outcome data will be collected by staff not involved in the HBB intervention. Additional data on resuscitations, resuscitation debriefings, death audits, quality monitoring and improvement will be collected. HBB training will include training of MTs, facility level birth attendants, and quality monitoring and improvement activities. Discussion: Our study will evaluate the effect of a HBB/ENC training and quality monitoring and improvement package on perinatal mortality using a large multicenter design and approach in 71 resource-limited health facilities, leveraging an existing birth registry to provide neonatal outcomes through day 7. The study will provide the evidence base, lessons learned, and best practices that will be essential to guiding future policy and investment in neonatal resuscitation.

Ancestral roles of the Fam20C family of secreted protein kinases revealed in C. elegans.

Fam20C is a secreted protein kinase mutated in Raine syndrome, a human skeletal disorder. In vertebrates, bone and enamel proteins are major Fam20C substrates. However, Fam20 kinases are conserved in invertebrates lacking bone and enamel, suggesting other ancestral functions. We show that FAMK-1, the Caenorhabditis elegans Fam20C orthologue, contributes to fertility, embryogenesis, and development. These functions are not fulfilled when FAMK-1 is retained in the early secretory pathway. During embryogenesis, FAMK-1 maintains intercellular partitions and prevents multinucleation; notably, temperature elevation or lowering cortical stiffness reduces requirement for FAMK-1 in these contexts. FAMK-1 is expressed in multiple adult tissues that undergo repeated mechanical strain, and selective expression in the spermatheca restores fertility. Informatic, biochemical, and functional analysis implicate lectins as FAMK-1 substrates. These findings suggest that FAMK-1 phosphorylation of substrates, including lectins, in the late secretory pathway is important in embryonic and tissue contexts where cells are subjected to mechanical strain
