To maintain a strategic distance from this condition and to enhance the personal satisfaction powerful waste administration is utilized. In proposed framework, squander container is checked with the sensors and GSM framework. An android application is utilized to screen data with respect to squander independent of area.

Muon-induced neutrons do not explain the DAMA data
We present an accurate model of the muon-induced background in the DAMA/LIBRA
experiment. Our work challenges proposed mechanisms which seek to explain the
observed DAMA signal modulation with muon-induced backgrounds. Muon generation
and transport are performed using the MUSIC/MUSUN code, and subsequent
interactions in the vicinity of the DAMA detector cavern are simulated with
Geant4. We estimate the total muon-induced neutron flux in the detector cavern
to be cm s. We predict
counts/day/kg/keV, which accounts for less than of
the DAMA signal modulation amplitude.Comment: 6 pages, 4 figures, accepted for publication in PR

First CNGS events detected by LVD
The CERN Neutrino to Gran Sasso (CNGS) project aims to produce a high energy,
wide band beam at CERN and send it toward the INFN Gran Sasso
National Laboratory (LNGS), 732 km away. Its main goal is the observation of
the appearance, through neutrino flavour oscillation. The beam
started its operation in August 2006 for about 12 days: a total amount of
protons were delivered to the target. The LVD detector, installed
in hall A of the LNGS and mainly dedicated to the study of supernova neutrinos,
was fully operating during the whole CNGS running time. A total number of 569
events were detected in coincidence with the beam spill time. This is in good
agreement with the expected number of events from Montecarlo simulations.Comment: Accepted for publication by the European Physical Journal C ; 7

On-line recognition of supernova neutrino bursts in the LVD detector
In this paper we show the capabilities of the Large Volume Detector (INFN
Gran Sasso National Laboratory) to identify a neutrino burst associated to a
supernova explosion, in the absence of an "external trigger", e.g., an optical
observation. We describe how the detector trigger and event selection have been
optimized for this purpose, and we detail the algorithm used for the on-line
burst recognition. The on-line sensitivity of the detector is defined and
discussed in terms of supernova distance and electron anti-neutrino intensity
at the source.Comment: Accepted for pubblication on Astroparticle Physics. 13 pages, 10

BUCCAL DRUG DELIVERY: A TECHNICAL APPROACH
Over the last few years Pharmaceutical scientists are trying to explore transdermal and transmucosal routes as an alternative to injections. Buccal delivery of the desired drug using mucoadhesive polymers has been the subject of interest since the early 1980s. Conventional dosage forms for delivery of drugs via the oral mucosa include solutions, erodible or chewable, buccal or sublingual tablets and capsules. Unfortunately, a major portion of the drug in these systems may be unavailable due to involuntary swallowing and a very short residence time, because of mastication, speech etc and hence sustained release is usually not within the scope of such Formulations and development of Novel bioadhesive dosage forms for mucosal delivery of drugs that attempt to overcome these limitations. We formulated buccal drug delivery, The buccal cavity was found to be the most convenient and easily accessible site for the delivery of therapeutic agents for both local and systemic delivery as retentive dosage forms. Because buccal Adhesive drug delivery system prolong the residence time of the dosage form at the site of application or absorption and facilitate an intimate contact of the dosage form with the limited absorption surface and thus contribute to improved better therapeutic efficacy of the drug. Buccal administration of drugs provides a convenient route of administration for both systemic and local drug actions. Buccal drug delivery has gained significant attention and momentum since it offers remarkable advantages. This review article is an overview of buccal drug delivery systems encompassing a review of oral mucosa, active ingredient delivered via buccal route by different mucoadhesive formulations. Including, commercial technologies and future prospects of this route of drug delivery are discussed
Search for low energy neutrinos in correlation with the 8 events observed by the EXPLORER and NAUTILUS detectors in 2001
We report on a search for low-energy neutrino (antineutrino) bursts in
correlation with the 8 time coincident events observed by the gravitational
waves detectors EXPLORER and NAUTILUS (GWD) during the year 2001. The search,
conducted with the LVD detector (INFN Gran Sasso National Laboratory, Italy),
has considered several neutrino reactions, corresponding to different neutrino
species, and a wide range of time intervals around the (GWD) observed events.
No evidence for statistically significant correlated signals in LVD has been
found. Assuming two different origins for neutrino emission, the cooling of a
neutron star from a core-collapse supernova or from coalescing neutron stars
and the accretion of shocked matter, and taking into account neutrino
oscillations, we derive limits to the total energy emitted in neutrinos and to
the amount of accreting mass, respectively.Comment: Accepted for publication in Astronomy and Astrophysic
Study of single muons with the Large Volume Detector at Gran Sasso Laboratory
The present study is based on the sample of about 3 mln single muons observed
by LVD at underground Gran Sasso Laboratory during 36500 live hours from June
1992 to February 1998. We have measured the muon intensity at slant depths from
3 km w.e. to 20 km w.e. Most events are high energy downward muons produced by
meson decay in the atmosphere. The analysis of these muons has revealed the
power index of pion and kaon spectrum: 2.76 \pm 0.05. The reminders are
horizontal muons produced by the neutrino interactions in the rock surrounding
LVD. The value of this flux is obtained. The results are compared with Monte
Carlo simulations and the world data.Comment: 13 pages, 2 figures, accepted for publication in "Physics of Atomic

Neutrino hierarchy from CP-blind observables with high density magnetized detectors
High density magnetized detectors are well suited to exploit the outstanding
purity and intensities of novel neutrino sources like Neutrino Factories and
Beta Beams. They can also provide independent measurements of leptonic mixing
parameters through the observation of atmospheric muon-neutrinos. In this
paper, we discuss the combination of these observables from a multi-kton iron
detector and a high energy Beta Beam; in particular, we demonstrate that even
with moderate detector granularities the neutrino mass hierarchy can be
determined for values greater than 4.Comment: 16 pages, 7 figures. Added a new section discussing systematic errors
(sec 5.2); sec.5.1 and 4 have been extended. Version to appear in EPJ
Upper Limit on the Prompt Muon Flux Derived from the LVD Underground Experiment
We present the analysis of the muon events with all muon multiplicities
collected during 21804 hours of operation of the first LVD tower. The measured
depth-angular distribution of muon intensities has been used to obtain the
normalization factor, A, the power index, gamma, of the primary all-nucleon
spectrum and the ratio, R_c, of prompt muon flux to that of pi-mesons - the
main parameters which determine the spectrum of cosmic ray muons at the sea
level. The value of gamma = 2.77 +/- 0.05 (68% C.L.) and R_c < 2.0 x 10^-3 (95%
C.L.) have been obtained. The upper limit to the prompt muon flux favours the
models of charm production based on QGSM and the dual parton model.Comment: 10 pages, 4 figures, RevTex. To appear in Phys. Rev.
