Spaceflight Influences both Mucosal and Peripheral Cytokine Production in PTN-Tg and Wild Type Mice
Justin L. McCarville, Sandra T. Clarke, Padmaja Shastri, Yi Liu, Martin Kalmokoff, Stephen P. J. Brooks, Julia M. Green-Johnson
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0068961
Abstract: Spaceflight is associated with several health issues including diminished immune efficiency. Effects of long-term spaceflight on selected immune parameters of wild type (Wt) and transgenic mice over-expressing pleiotrophin under the human bone-specific osteocalcin promoter (PTN-Tg) were examined using the novel Mouse Drawer System (MDS) aboard the International Space Station (ISS) over a 91 day period. Effects of this long duration flight on PTN-Tg and Wt mice were determined in comparison to ground controls and vivarium-housed PTN-Tg and Wt mice. Levels of interleukin-2 (IL-2) and transforming growth factor-beta1 (TGF-β1) were measured in mucosal and systemic tissues of Wt and PTN-Tg mice. Colonic contents were also analyzed to assess potential effects on the gut microbiota, although no firm conclusions could be made due to constraints imposed by the MDS payload and the time of sampling. Spaceflight-associated differences were observed in colonic tissue and systemic lymph node levels of IL-2 and TGF-β1 relative to ground controls. Total colonic TGF-β1 levels were lower in Wt and PTN-Tg flight mice in comparison to ground controls. The Wt flight mouse had lower levels of IL-2 and TGF-β1 compared to the Wt ground control in both the inguinal and brachial lymph nodes, however this pattern was not consistently observed in PTN-Tg mice. Vivarium-housed Wt controls had higher levels of active TGF-β1 and IL-2 in inguinal lymph nodes relative to PTN-Tg mice. The results of this study suggest compartmentalized effects of spaceflight and on immune parameters in mice.

The glasses were investigated for room temperature density and electrical conductivity in the temperature range 300 - 523 K and in the frequency range 102 to 105 Hz. The frequency and temperature dependence of conductivity as dielectric constant are presented.

New Cloud Detection Index (CDI) for Forecasting the Extreme Rain Events  [PDF]
Niket Shastri, Kamlesh Kamlesh Pathak
Advances in Remote Sensing (ARS) , 2019, DOI: 10.4236/ars.2019.81002
Abstract:

The water vapor content and clouds play a very significant role in atmospheric conditions. This paper is derived from the new cloud detection index (CDI) which is useful to forecast extreme weather events like heavy or extreme rain. The CDI is retrieved using two crucial elements of cloud formation, the critical humidity and critical water vapor. The cloud thickness is determined by using CDI for a radiosonde site (VABB) located in Mumbai, the western part of India. The obtained results are compared with the cloud thickness required for extreme rain. The outcome of the comparison is discussed in this paper. The cloud detection index is also useful in establishing the atmospheric stability along with another four atmospheric stability indices.



Free media, labour and citizenship rights in a democracy
Shaw,Padmaja;
Observatorio (OBS*) , 2011,
Abstract: india is the most populous democracy in the world. in the early years after attaining independence, as a new democracy, indian development strategy was driven by what francine frankel (2005) calls the ?the gandhian-socialist consensus? that was predominantly value oriented. frankel enumerates the areas of consensus - first, there was the general agreement that economic policy should aim for the progressive removal of inequalities in indian society, and ultimately result in the complete disappearance of class distinctions. second, the gandhians and the socialists concurred on the need to limit sharply the existing scope of the acquisitive instinct in indian economic life, and to create a new set of cooperative motives. the nehruvian socialist state envisioned a strong industrial base under state ownership (frankel, 2005) and wage labour was seen within the ethical context of productive employment and as a defining frame for good citizenship. this and the constitutional guarantee of fundamental rights helped to give legitimacy to wage labour?s expectation of citizenship rights through provision of jobs, better working conditions, better social services and healthcare. by the 1990s, after economic liberalization, the basic premises of this vision were discarded even in populist political rhetoric, while the state embraced neo-liberal ideology and economic policies. the changed economic agenda impacted severely on the working classes. primarily because of the nature of growth and specifically because of the pressure from the indian industrial houses, the policies encouraged relaxation of the already weakly implemented labour laws. this paper will examine the role media played in debating these issues. as media are event oriented and not process oriented in their coverage, coverage of labour issues is unlikely on an ordinary news day. this paper, therefore, will examine the news and opinion pieces that have appeared in mainstream media when the ceo of a multinational aut
A Study on web Applications & Protection against Vulnerabilities
Padmaja K
International Journal of Engineering Research and Applications , 2012,
Abstract: Web applications are widely adopted and their correct functioning is mission critical for many businesses. Online banking, emails, eshopping, has become an integral part of today’s life. Vulnerabilities in web application can lead to a variety of erroneous behavior at dynamic run time. We encounter the problem of forceful browsing in many web applications, username enumeration can help an attacker who attempts to use guessable passwords, such as test/test, admin/admin, guest/guest, and so on. These accounts are often created by developers for testing purposes, and many times the accounts are never disabled or the developer forgets to change the password, hacking reduces the performance or function of the application, further more, the modified system itself becomes a constraint to counter newer types of vulnerabilities that may crop up from time to time. Hence, the best solution would be to finds the steps to solve that are web-based (firewall) independent for protecting against vulnerabilities in web applications. In our work algorithm is to analyze vulnerabilities that are caused by breaking of the data dependency using problem which work efficient with existing one.
Liquid-Supported Denture & Neutral Zone for Atrophic Residual Ridges : A Case Report
Padmaja S
People's Journal of Scientific Research , 2012,
Abstract: Liquid supported denture can be a permanent solution in edentulous patients with diabetes, xerostomia andatrophied ridge. A liquid-supported denture was planned for maxillary arch and neutral zone concept for fabrication ofcontour of the polished surfaces of mandibular denture. Liquid-supported dentures will have optimal stress distributionduring masticatory function. The neutral zone technique provides muscular harmony over the denture stability. Liquidsupported denture will act as a continuous reliner for the denture and thus has an advantage over the conventionaldenture. Neutral zone technique is an alternative approach for the construction of mandibular dentures where there isatrophic ridge and a history of denture instability.

Abstract: Aim: To know the Haemato-Biochemical values of camels infested with Trypanosomiasis. Materials and Methods: A herd of 13 camels showing signs of inappetance, lethargy, going down in condition, urticarial swellings, oedema of pads and occasional shivering were examined. Blood samples were collected to screen for the trypanosomes and to record hemato-biochemical alterations. Treatment of both group I and group II was undertaken. Results: Nine camels were positive for Trypanosomes recording an incidence of 69.23%. A significant (P<0.01) increase in temperature and decrease in TEC was observed, while a significant (P<0.05) increase in TLC, neutrophils and eosinophils and significant (P<0.05) decrease in lymphocytes was noted in positive blood samples. Significant (P<0.05) decrease in blood glucose levels was recorded and one camel died due to hypoglycemic encephalopathy. Trypanosomiasis was treated successfully with Quinapyramine salts. [Vet.

International Journal of Reproduction, Contraception, Obstetrics and Gynecology , 2013, DOI: 10.5455/2320-1770.ijrcog20130954
Abstract: Hyperandrogenism is the most common endocrine disorder in reproductive age group. While 82% of the cases are due to PCOS, steroid cell tumours account for less than 1% of cases. These tumours are mostly seen in perimenopausal women and 25-30% of these tumours show malignant potential. Hysterectomy with bilateral salpingo-oophorectomy is the recommended treatment. In a young patient unilateral salpingo-oophorectomy and subsequent follow up can be offered. We present one such rare case of a young patient coming with menstrual irregularities, virilising symptoms and infertility, all features mimicking PCOS. She was diagnosed with a steroid cell tumour and successfully treated. [Int J Reprod Contracept Obstet Gynecol 2013; 2(3.000): 482-484]

Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.96070
Abstract: Personality is the psychological characteristics that make each and every individual unique. Personality is related to both traits and states, where traits are considered to be the characteristics which are there for longer period of time like temperament and states are the characteristics which are considered to be changeable like mood. Both states and traits in personality are considered to be developed at early stages in life where the hereditary psychological and social influences are the most responsible causes for the formation of the personality. This research paper will give the broad overview of how music affects to the personality and behaviour of infants.
