Response of Grape Rootstocks to Soil Moisture Stress

Studies on root and shoot morphology, endogenous hormones and water use efficiency in five grape rootstocks namely Dogridge, 1613 C, Salt Creek, St. George and Vitis champinii clone (VC Clone) at three levels of moisture stress viz., no stress (100% irrigation), 50% stress (50% irrigation) and 100% stress (without irrigation) for 14 days revealed that Dogridge and Salt Creek rootstocks maintained the highest ratios of root to shoot length and root to shoot dry weight as compared to other rootstocks. Water use efficiency increased with increased soil moisture stress and was the highest in Dogridge and Salt Creek. The abscisic acid content in the leaves of Dogridge was maximum at 50% stress followed by that of Salt Creek. Similarly the cytokinin content (both t-ZR and DHZR) was minimum in Dogridge and Salt Creek at 50% stress while it was maximum in 1613 C and St.George. The root to shoot length ratio was positively correlated with ABA content under moisture stress conditions. The higher levels of abscisic acid content in Dogridge and Salt Creek under soil moisture stress suggested their better drought tolerance capacity through a reduction of stomatal conductance and increased water use efficiency

Effect of Muons on the Phase Transition in Magnetised Proto-Neutron Star Matter

We study the effect of inclusion of muons and the muon neutrinos on the phase transition from nuclear to quark matter in a magnetised proto-neutron star and compare our results with those obtained by us without the muons. We find that the inclusion of muons changes slightly the nuclear density at which transition occurs.However the dependence of this transition density on various chemical potentials, temperature and the magnetic field remains quantitatively the same.Comment: LaTex2e file with four postscript figure

Extracellular vesicle-mediated transfer of processed and functional RNY5 RNA

Extracellular vesicles (EVs) have been proposed as a means to promote intercellular communication. We show that when human primary cells are exposed to cancer cell EVs, rapid cell death of the primary cells is observed, while cancer cells treated with primary or cancer cell EVs do not display this response. The active agents that trigger cell death are 29- to 31-nucleotide (nt) or 22- to 23-nt processed fragments of an 83-nt primary transcript of the human RNY5 gene that are highly likely to be formed within the EVs. Primary cells treated with either cancer cell EVs, deproteinized total RNA from either primary or cancer cell EVs, or synthetic versions of 31- and 23-nt fragments trigger rapid cell death in a dose-dependent manner. The transfer of processed RNY5 fragments through EVs may reflect a novel strategy used by cancer cells toward the establishment of a favorable microenvironment for their proliferation and invasion

Analysis of medication errors in medicine ward of medical college teaching hospital, Mandya

Background: Medication errors are one of the most common types of medical error that is seen in hospitalised patients. Since medication error is one of the growing concerns of healthcare issue and have implications on patient safety, the purpose of this study was to identify medication error and in turn would help to create awareness among healthcare professionals and provide safety to the patients.Methods: Study was initiated after obtaining approval from the Institutional Ethics Committee. The study was done for a period of 1 year between June 2016 and May 2017. Clinical data and data regarding the medication that was prescribed, transcribed, dispensed, administered was collected and was analysed for various types of medication errors during the different stages of medication use process.Results: A total of 351 subjects were recruited in the study for assessing medication error. About 2,283 drugs were prescribed among 351 patients. Maximum number of drugs was administered through parenteral route (50.3%). Medication error was most common during the prescribing stage (51.4%) followed by transcribing stage (39.1%), administration stage (6.9%), and dispensing stage (2.6%). On an average 6 drugs were prescribed per patient. Total of about 5411 errors have occurred out of which 98.8% of errors were preventable, 1.2% of errors were non-preventable. Cardiovascular system (21.9%) and endocrine and renal system (21.9%) was commonly affected due to the medication errors.Conclusions: Medication errors are one of the commonest problems of the healthcare system should be identified and documented and their causes should be studied in order to develop systems that minimize the recurrence

Assessment of Radon in groundwater and associated human risk from Sankarabarani River Sub Basin, Southern India

Radon (222Rn) and associated human risk assessment in groundwater from quaternary shallow aquifers of Sankarabarani River sub basin, Southern India has been attempted by considering 41 groundwater samples and analysed for 222Rn using scintillation Radon monitoring system. The Radon ranges between 0.140±0.01 Bq l-1 to 7.869±0.33 Bq l-1 with an average of 1.797±0.12Bq l-1 and found to be within the maximum contamination level of Environmental Protection Agency (11.1 Bq l-1). The doses of ingestion and inhalation calculated for radon varies between 0.709 µSv y-1 to 39.933µSv y-1 with an average of 9.121µSv y-1which is within the prescribed dose limit of 100µSv y-1 by World Health Organisation. Uranium speciation attempted suggests saturated Haiweeite and Soddyite as sources for uranium/radon into the aquifer systems. The Eh-pH diagram suggests uraninite solubility within the pH ranges 6 to 8 within the groundwater environment

Unpolarized light in quantum optics

We present a new derivation of the unpolarized quantum states of light, whose general form was first derived by Prakash and Chandra [Phys. Rev. A 4, 796 (1971)]. Our derivation makes use of some basic group theory, is straightforward, and offers some new insights.Comment: 3 pages, REVTeX, presented at ICQO'200
