Dama Technologies specializes in the manufacture of machines which are able to process glass, ceramics and other hard-brittle materials at high precision. One of the highlights of the program is the five-axis, USG 500 ultrasound-assisted grinder, in which a hightorque Lehmann EA 520.L rotary table functions as a swiveling machine table. It contains a high-speed torque axis, which was manufactur...

We examine the effect of some uncertainties in the input astrophysical parameters on direct detection searches for WIMPs in the Galactic halo. We concentrate on the possible WIMP annual modulation signal recently reported by the DAMA Collaboration. We find that allowing for a reasonable uncertainty in a WIMP Maxwellian velocity distribution leads to significantly relaxed constraints on the WIMP...

One IGEX Ge double-beta decay detector is currently operating in the Canfranc Underground Laboratory in a search for dark matter WIMPs, through the Ge nuclear recoil produced by the WIMP elastic scattering. A new exclusion plot, σ(m), has been derived for WIMP-nucleon spin-independent interactions. To obtain this result, 40 days of data from the IGEX detector (energy threshold Ethr ∼ 4 keV), re...

We review the records of 79 tetanus patients in two hospitals (one tertiary and one secondary level) in Owo, Ondo state, Nigeria from 1997 to 2006. The male: female ratio was 3:1. Ages were 14-70 years (mean 33.25 years, SD ±16.76). The overall case fatality rate (CFR), 32.91%, did was not significantly different in the two hospitals. CFR for men was 32.10% and for women 35.29%. The main factor...

DDoS (Distributed Denial of Service) attack is being the most extensive danger and difficulty to defense. A new kind of DDoS attack named DRDoS (Distributed Reflector Denial of Service) appears in recent years, which is more dangerous than DDoS attack because it is in stronger disguise. In this paper, the principle of DRDoS attack is studied and the network traffic is analyzed by fuzzy associat...

Experimental observations and theoretical arguments at Galaxy and larger scales have suggested that a large fraction of the Universe is composed by Dark Matter particles. This has motivated the DAMA experimental efforts to investigate the presence of such particles in the galactic halo by exploiting a model independent signature and very highly radiopure setup in deep underground. Few introduct...

The diet choice of large herbivores is influenced by the presence of nutrients and toxins in available plants. It is generally assumed that herbivores ingest food that contains higher amounts of nutrients and lower amounts of toxins than the average of the food available. We studied the effects of quality and relative abundance on food choice in fallow deer, Dama dama. Preferences for and avers...
