Pinning down neutrino oscillation parameters in the 2-3 sector with a mgnetised atmospheric neutrino detector: a new study

We determine the sensitivity to neutrino oscillation parameters from a study of atmospheric neutrinos in a magnetised detector such as the ICAL at the proposed India-based Neutrino Observatory. In such a detector that can {\em separately} count $\nu_\mu$ and $\overline{\nu}_\mu$-induced events, the relatively smaller (about 5\%) uncertainties on the neutrino--anti-neutrino flux ratios translate to a constraint in the $\chi^2$ analysis that results in a significant improvement in the precision with which neutrino oscillation parameters such as $\sin^2\theta_{23}$ can be determined. Such an effect is unique to all magnetisable detectors and constitutes a great advantage in determining neutrino oscillation parameters using such detectors. Such a study has been performed for the first time here. Along with an increase in the kinematic range compared to earlier analyses, this results in sensitivities to oscillation parameters in the 2--3 sector that are comparable to or better than those from accelerator experiments where the fluxes are significantly higher. For example, the $1\sigma$ precisions on $\sin^2\theta_{23}$ and $|\Delta{m^2_{32(31)}}|$ achievable for 500 kTon yr exposure of ICAL are $\sim9\%$ and $\sim2.5\%$ respectively for both normal and inverted hierarchies. The mass hierarchy sensitivity achievable with this combination when the true hierarchy is normal (inverted) for the same exposure is $\Delta\chi^2\approx8.5$ ($\Delta\chi^2\approx9.5$)

YUGI’S CONCEPT OF GUNMAM PATIENTS REPORTING AT AYOTHIDOSS PANDITHAR HOSPITAL, NATIONAL INSTITUTE OF SIDDHA (NIS) - A CROSS SECTIONAL STUDY

According to Siddha system of medicine disease are numbered as 4448. One among them is Gunmam. Severe pain in the abdomen occurs as one of the symptoms and this makes the patient to bend forward in order to get relief from pain and hence the name is mentioned as Gunmam. As per sage Yugi, Gunmam is further classified into 8 types. The human body runs on the basis of Vatham, Pitham, Kabam and due to changes in the equilibrium of tri-dosha mankind acquires disease. As per Theraiyar Gunmam occurs due to vitiation of Vali thathu. Common symptoms of Gunmam are indigestion, vomiting, abdominal pain, abdominal distension, decrease body weight, loss of confidence. The signs and symptoms of Gunmam can be correlated to Acid Peptic Disease (APD). This study was undertaken to assess the incidence of different types of Gunmam patients reporting at OPD of Ayothidoss Pandithar Hospital. This is hospital based cross sectional study conducted in Ayothidoss Pandithar Hospital between months of May 2019 and July 2019. The study was given ethical approval by institutional Ethics Committee. The study included the completion of questionnaire which focuses on symptoms of eight types of Gunmam, thega ilakkanam, behavioural risk factors for Gunmam and physical measurements from randomly selected patients reporting to the OPD. Using Systematic random sampling method, 250 patients were selected from the OPD of Ayothidoss Pandithar Hospital. Statistical analysis was done using SPSS software. Among 250 Gunmam patients, 33.2% of subjects are Pitha thegi, 32.8% of subjects are Eri gunmam

Note on the mottled fusilier Dipterygonotus balteatus (Valenciennes, 1830) landed along Tamil Nadu coast

Unusual landing of the mottled fusilier Dipterygonotus balteatus was observed along the northern coast of Tamil Nadu during July and September 2006. Mottled fusiliers belong to the percoid family Caesionidae. While the juveniles are known to school together with other caesionids on coral reefs, the adults are usually distributed in near shore pelagic waters. D. balteatus occurs in Indo- Pacific waters, from East Africa, off Lakshadweep, Sri Lanka, Indonesia, to Philippines, Indo-China and northern Australia

Study of neutrino oscillation parameters at the INO-ICAL detector using event-by-event reconstruction

We present the reach of the proposed INO-ICAL in measuring the atmospheric-neutrino-oscillation parameters $\theta_{23}$ and $\Delta m^2_{32}$ using full event-by-event reconstruction for the first time. We also study the fluctuations in the data and their effect on the precision measurements and mass-hierarchy analysis for a five-year exposure of the 50 kton ICAL detector. We find a mean resolution of $\Delta\chi^2 \approx 2.9$, which rules out the wrong mass hierarchy of the neutrinos with a significance of approximately $1.7\sigma$. These results are similar to those to presented earlier studies that approximated the performance of the ICAL detector

COMPARATIVE EFFICACY OF CLOVE OIL AND 2-PHENOXY ETHANOL ON SERUM BIOCHEMICAL CHANGES AND HISTOLOGICAL STUDIES IN CHANNAPUNCTATUS

The aim of the present study was to investigate thecomparison of effect of clove oil and 2-phenoxy ethanol for Channapunctatus and using values of serum biochemical profile and histological tissue studies ,to assess the effects of fish exposure to that anaesthetic:A total of 60 C.punctatus of 60.23±5.02g were divided in to five groups (12 fish per each):1st treatment as control (no anaesthetic),2nd 0.2ml/1 2-phenoxy ethanol ,3rd 0.3ml/1 2-phenoxy ethanol ,4th 30mg/1 clove oil and 5th 40mg/1 clove oil.Biochemical blood profile of C.puntatus were taken 15 min and 24 hrs. After Anaesthesia induction ,the factors used to evaluate the serum biochemical profile included the glucose (GLU), total protein (TP), albumin (ALB),total globulin (GLOP), alkaline phosphatase (ALP),serum Glutamic oxaloacetic Transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), histological tissue examination of tissue like gills ,ten minutes exposure to 2-phenoxy ethanol and clove oilcaused an increase in concentration of glucose and alkaline phosphatase 15 min after Anaesthesiainduction.Histological examination showed.Capillary ectasia of gill filaments immediately after clove oil and 2-phenoxy ethanol,showed  swelling of primary and secondary lamella .Twenty –four hours after anaesthesia ,no ectasia was observed .No histopathological changes were demonstrated in gills:Our result showed that The 2-phenoxy ethanol at 0.20ml/1and clove oil at 30mg/1 concentration may be used as an efficient and safe anaesthetic for Channapunctatus. Key words: Clove oil, 2-Phenoxy ethanol,Channapunctaus,Serum biochemical profile, histological examination of tissues

Hadron energy response of the Iron Calorimeter detector at the India-based Neutrino Observatory

The results of a Monte Carlo simulation study of the hadron energy response for the magnetized Iron CALorimeter detector, ICAL, proposed to be located at the India-based Neutrino Observatory (INO) is presented. Using a GEANT4 modeling of the detector ICAL, interactions of atmospheric neutrinos with target nuclei are simulated. The detector response to hadrons propagating through it is investigated using the hadron hit multiplicity in the active detector elements. The detector response to charged pions of fixed energy is studied first, followed by the average response to the hadrons produced in atmospheric neutrino interactions using events simulated with the NUANCE event generator. The shape of the hit distribution is observed to fit the Vavilov distribution, which reduces to a Gaussian at high energies. In terms of the parameters of this distribution, we present the hadron energy resolution as a function of hadron energy, and the calibration of hadron energy as a function of the hit multiplicity. The energy resolution for hadrons is found to be in the range 85% (for 1GeV) -- 36% (for 15 GeV).Comment: 14 pages, 10 figures (24 eps files
