In the next chapters we are going to give an overview of the main WIMP search strategies, which fall in three big categories: • Direct searches probe the scattering cross section of WIMPs with nuclei, by looking for nuclear recoils in some target material in a low background environment. When a WIMP of the galactic halo passes through the target, it may scatter off a nucleus, whose recoil will ...

This review on weakly interacting massive particle (WIMP) dark matter direct detection focuses on experimental approaches and the corresponding physics basics. The presentation is intended to provide a quick and concise introduction for non-specialists to this fast evolving topic of astroparticle physics.
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
We have developed an improved method for the analysis of human urine for 1-hydroxypyrene (1-HOP), an accepted biomarker of polycyclic aromatic hydrocarbon uptake. This method takes advantage of commercially available 96-well format devices, which expedite sample preparation before quantitation by HPLC with fluorescence detection. In addition to improved speed of analysis, which is critical for ...
lurestan province is petroliferous area. the reserved oil are in ilam and sarvak (cretaceous ) and kangan ( lower triassic ) and dalan (permian) formations. the lurestan area had high exploration activity but contribution of source rocks in hydrocarbon accumulations isn’t clear. in this paper essential elements and process of hydrocarbon accumulation are introduced. candidate source rocks ar...
faults/fractures detection is an essential step of the full field study in hydrocarbon reservoir. definition of exact location of these structural events is a critical step to optimize location of the development wells. despite of the fast development of the geo science technology and oil industry in recent years, detection of the small geological events such as faults and fractures in some of ...
