In vitro regeneration of Basella alba L

Basella alba L. is a tropical vine used as a vegetable in some Asian and African countries. It has potential as a nontraditional crop for small family farms. A short day plant, it blooms during the fall, provided the temperatures are mild. In the southeastern U.S., the short days of fall are associated with subfreezing temperatures, and plants are killed before blooming. Attempts were made to regenerate the plant using tissue culture techniques. Several trials were conducted with different media, hormones, and explants. It was found that nodal segments on Gamborg medium regenerated shoots. Interaction studies of auxins and cytokinins indicated that its endogeneous auxin content might be high because callus proliferated in almost all treatments and roots initiated even when the medium was not supplemented with an auxin

Metaphorizing Grammar And Writing: Visual Learning In The English Classroom

My goals for this thesis include exploring how metaphors are used in the classroom and, in doing so, providing ways in which to help both teachers and students transcend their understanding. I will: (1) analyze and respond to the research on metaphors in the classroom, (2) illustrate and discuss the rationale of different metaphors I have collected from teachers as well as some I created for the English classroom, and (3) share student generated metaphors in the English classroom

Perspectives on domestic violence: case study from Karachi, Pakistan.

There is no adequate profile of domestic violence in Pakistan although this issue is frequently highlighted by the media. This case study used qualitative and quantitative methods to explore the nature and forms of domestic violence, circumstances, impact and coping mechanisms amongst selected women victims in Karachi. Violence was a continuum: all the women reported verbal abuse, often escalating into physical, emotional, sexual and economic abuse. The husband was the most common perpetrator. Women suffered in silence due to sociocultural norms, misinterpretation of religious beliefs, subordinate status, economic dependence and lack of legal redress. Besides short-term local measures, public policy informed by correct interpretation of religion can bring about a change in prevailing societal norms

Women’s health in developing countries

Healthcare priorities are different in developing and developed countries. A more effective resource allocation, complemented by efforts to implement only those practices that are effective, should be a priority for improving reproductive health services in developing countries. A large burden of gynaecological disease exists in developing countries and it is difficult to envisage serious reforms and improvements without an increase in public-sector spending. However, communities themselves could assume some responsibility for women\u27s health in ways that prioritize women\u27s own perceptions and primary needs. In this chapter we have compiled existing evidence regarding various gynaecological problems faced by women in developing countries. To name a few: sexual health issues, abortion, subfertility, cancer, and genital fistulae. We believe that there is a large knowledge gap in the area of women\u27s health in developing countries, and there is an urgent need to conduct appropriately designed studies

Critical appraisal of endometriosis management for pain and subfertility

Objective: To critically appraise current best available management of pain and subfertility ascribable to endometriosis.Methods: Medline and specialist computer databases were searched along with reference lists of known reviews and primary articles to identify cited articles not captured by electronic searches. We included all studies pertaining to treatment of pain and subfertility ascribable to endometriosis.Discussion: Medical and surgical management options for pain and subfertility are presented as Evidence-based inquiries for critically appraised topics. Each problem is presented as an answerable question followed by assessment of literature search for level of evidence. This is followed by critical appraisal of results. In the end, take-home answer to individual problem is presented in view of best available evidence.Conclusion: Evidence-based management of endometriosis provides realistic therapeutic goals and expectations for the clinicians and women experiencing pain and subfertility due to this disease. It also promotes efficient and effective use of medical and surgical options when required

Developing Lunar Flashlight and Near-Earth Asteroid Scout Flight Software Concurrently using Open-Source F Prime Flight Software Framework

NASA’s Lunar Flashlight (LF) and Near-Earth Asteroid (NEA) Scout CubeSat missions are planned to launch in 2022. Lunar Flashlight is a low-cost secondary payload concept that will map the lunar South Pole for volatiles and demonstrate several technological firsts, including the first planetary CubeSat mission to use green propulsion, and the first mission to use lasers to look for water ice. NEA Scout is a low-cost concept that will map an asteroid and demonstrate several technological firsts, including being the first CubeSat to reach an asteroid. Flight software for both CubeSat missions is based on the open-source F Prime Flight Software Product Line developed by JPL. F Prime utilizes a reusable component-based architecture with typed ports that can be interconnected to form a topology. Also, F Prime includes a set of auto-coding tools used to generate components and topologies that can be deployed for various mission specific applications. Both CubeSats share a common set of avionics for command and data handling (C&DH), telecom and power. This commonality in hardware is translated to a shared deployment in software enabling concurrent flight software development for both CubeSats. The modularity and reusability in F Prime enable such concurrent flight software development for different applications given a common set of avionics. In particular, F Prime has been used successfully to develop a common software deployment for the Sphinx C&DH platform used on both CubeSats. The common F Prime deployment for Sphinx has also been made open source to provide a starting point for any future F Prime software deployments utilizing the Sphinx platform. This paper provides a comparison between the Lunar Flashlight and NEA Scout Flight Software deployments highlighting the use of a common shared set of F Prime components developed for the Sphinx platform along with general lessons learned for CubeSat flight software development with the F Prime Framework

EFFECT OF PIGEON ORIGIN NEWCASTLE DISEASE VIRUS ON VARIOUS LIVER ENZYMES AND ASSOCIATED PATHOLOGICAL CHANGES IN EXPERIMENTALLY INFECTED PIGEONS

Newcastle disease virus (NDV) was isolated from a field outbreak in pigeons. The virus was characterized by haemagglutination test (HA) and confirmed by haemagglutination inhibition test (HAI). The pathotyping was done by mean death time (MDT), intracerebral pathogenicity index (ICPI) and intravenous pathogenicity index (IVPI). The ELD50 of the velogenic strain was 10-4.66/0.1 ml. Thirty-nine pigeons were randomly divided into three equal groups. Pigeons of one group were vaccinated with ND vaccine (LaSota strain) intraocularly after 14 days of procurement, while the other two groups served as vaccinated and non-vaccinated controls. Birds of these two groups were challenged with velogenic strain of field isolate of NDV 7 days post-vaccination. Birds were kept under observation for 15 days post-challenge. Haemorrhages and congestion were observed in trachea, lungs, liver, proventriculus and intestine of pigeons infected with NDV. Concentrations of AST, ALT and ALP did not differ among pigeons of the three groups

Single-molecule study for a graphene-based nano-position sensor

In this study we lay the groundwork for a graphene-based fundamental ruler at the nanoscale. It relies on the efficient energy-transfer mechanism between single quantum emitters and low-doped graphene monolayers. Our experiments, conducted with dibenzoterrylene (DBT) molecules, allow going beyond ensemble analysis due to the emitter photo-stability and brightness. A quantitative characterization of the fluorescence decay-rate modification is presented and compared to a simple model, showing agreement with the $d^{-4}$ dependence, a genuine manifestation of a dipole interacting with a 2D material. With DBT molecules, we can estimate a potential uncertainty in position measurements as low as 5nm in the range below 30nm
